The present disclosure generally relates to disposable diaper having absorbent cores comprising superabsorbent polymer particles which are immobilized by adhesive. The absorbent core is attached to the backsheet of the disposable diaper only in certain attachment zones to reduce see-through and the formation of tension lines on the backsheet.
The use of superabsorbent polymer material in disposable diapers is generally known. The use of superabsorbent polymer material facilitates disposable diapers having a thinner absorbent core versus the use of absorbent materials such as fluff pulp, especially while the disposable diaper is in the dry state.
Today, most disposable diapers which are commercially available still have absorbent cores containing a mixture of so-called airfelt (cellulose fibers) and superabsorbent polymer particles. The cellulose fibers comprised by the absorbent core generally hold the superabsorbent polymer particles in place as the cellulose fibers entangle the particles such that the particles are trapped between the cellulose fibers. This generally does not result in a complete immobilization of the superabsorbent polymer particles, as the particles still may have some degree of freedom to move within the interstices between the cellulose fibers. However, the superabsorbent polymer particles are held in the desired position to a sufficiently satisfying degree.
Using higher amounts of superabsorbent polymer particles is desirable as it enables thinner absorbent cores. However, in absorbent cores having high amounts of superabsorbent polymer particles and little or no airfelt, the superabsorbent polymer particles can no longer be held in place in the interstices between the cellulose fibers, as the ratio of superabsorbent polymer particles to cellulose fibers is too high. Therefore, in absorbent cores having very high amounts of superabsorbent polymer particles (such as >80%), the particles have to be immobilized by some other means. One way to facilitate immobilization is the use of adhesive, such as hot melt adhesive. The hot melt adhesive may be applied as a fine, fibrous network within the absorbent core. Further, in absorbent cores having a high percentage of superabsorbent polymer material and little or no airfelt the superabsorbent polymer material is often sandwiched between carrier substrates. The carrier substrates are typically nonwoven webs.
Absorbent cores having relatively high amounts of superabsorbent polymer particles immobilized by hot melt adhesive and having little or no airfelt have few to no interstices (e.g. those provided between cellulose fibers). Thus, there is no available “free space” within the absorbent core into which the superabsorbent polymer particles can expand upon absorption of liquid. In these absorbent cores the superabsorbent polymer particles, upon swelling, will exert a certain force onto the nonwoven webs, which typically enwrap and encompass the superabsorbent polymer particles. Consequently, the nonwoven webs will also elongate in order to accommodate for the additional space needed by the swelling superabsorbent polymer particles within the absorbent core.
It has been found that an elongated and somewhat strained absorbent core, when incorporated in a disposable diaper, which has been attached onto a wearer, may result in a strained appearance of the backsheet, leading e.g. to the formation of tension lines or wrinkles Such tensed appearance may give raise to concerns by wearers or—if the wearers are babies or toddles—by the caretakers regarding the overall quality and especially the capacity of the disposable diaper. The tensed appearance may be perceived as an indication that the disposable diaper has reached its maximum load and needs to be replaced even if in fact a considerable amount of absorbent capacity is still available. The caretakers or wearers may thus attempt to change the diaper even if the absorbent core may still have the capacity to absorb further gushes of urine.
There is thus a need for disposable diapers with absorbent cores having high amounts of superabsorbent polymer particles and little to no airfelt, wherein, when only partly loaded with liquid, the backsheet may not have a strained appearance, especially when attached onto a wearer.
The present disclosure generally relates to a disposable diaper comprising a backsheet, a topsheet and therein between an absorbent core. The absorbent core has a longitudinal direction with a longitudinal axis and perpendicular thereto a lateral direction with a transverse axis, and the absorbent core further has a front region, a back region and a crotch region therein between and a front lateral edge, an opposing back lateral edge, and longitudinally extending side edges.
The absorbent core comprises superabsorbent polymer particles, which are immobilized by a first core adhesive. The absorbent core is attached to the backsheet according to one of the following options:
The absorbent core is attached to backsheet of the disposable diaper in attachment zones adjacent to the front lateral edge and the back lateral edge of the absorbent core and the absorbent core is unattached to the backsheet in any other region; or
The absorbent core is attached to the backsheet of the disposable diaper in the crotch region of the absorbent core in one or more than one attachment zone(s) on or adjacent to the longitudinal axis of the absorbent core, wherein the one or more than one attachment zone(s) cover from 0.2% to 3% of the total surface area of the absorbent core, and the absorbent core is unattached to the backsheet in any other region; or
The absorbent core is attached to the backsheet of the disposable diaper in the crotch region of the absorbent core in attachment zones adjacent to the longitudinal side edges of the absorbent core and the absorbent core is unattached to the backsheet in any other region; or
The absorbent core is attached to the backsheet of the disposable diaper in combinations of any of the attachment zones of a) to c) and the absorbent core is unattached to the backsheet in any other region.
Definitions
“Absorbent core” means a structure that is disposed between a topsheet and a backsheet of a disposable diaper for absorbing and containing liquid received by the disposable diaper.
“Airfelt” is used herein to refer to comminuted wood pulp, which is a form of cellulose fibers (absorbent fibers).
“Diaper” refers to an absorbent article generally worn by infants and incontinent persons about the lower torso so as to encircle the waist and legs of the wearer and which is specifically adapted to receive and contain urinary and fecal waste. For the present disclosure, the term “diaper” is considered to encompass “diaper pants”.
“Diaper-pant”, as used herein, refers to disposable garments having a waist opening and leg openings designed for infant or adult wearers. A diaper-pant may be placed in position on the wearer by inserting the wearer's legs into the leg openings and sliding the pant into position about a wearer's lower torso. A diaper-pant may be preformed by any suitable technique including, but not limited to, joining together portions of the article using refastenable and/or non-refastenable bonds (e.g., seam, weld, adhesive, cohesive bond, fastener, etc.). A diaper-pant may be preformed anywhere along the circumference of the article (e.g., side fastened, front waist fastened). The terms “diaper-pant” is also commonly referred to as “prefastened diaper,” “pull-on diaper,” “training pant,” and “pant”.
“Disposable” is used in its ordinary sense to mean an article that is disposed or discarded after a limited number of usage events over varying lengths of time, for example, less than 10 events, less than 5 events, or less than 2 events. A disposable absorbent article is most often disposed after single use.
“Hot melt adhesive” as used herein refers to adhesives in alignment with the description given in “Adhesion and Adhesives Technology: An Introduction” by Alphonsus V. Pocius (Hanser publishers Munich, 1997). Therein a hot melt is defined as an adhesive applied from the melt and gaining strength upon solidification.
“Non-elastic” as used herein refers to a backsheet which does not recover by more than 20% if subjected to the following test:
A rectangular piece of backsheet material (such as a film or a nonwoven or—if the backsheet comprises a film and a nonwoven web—both materials taken together in the configuration in which they are used as backsheet material) having a width of 2.54 cm and a length of 25.4 cm is maintained in a vertical position by holding the piece along its upper 2.54 cm wide edge along its complete width. A force of 10 N is applied onto the opposite lower edge along the complete width of the material for 1 minute at 25° C.
Immediately after one minute, the length of the piece is measured while the force is still applied and the degree of elongation is calculated by subtracting the initial length (10 inch) from the length measured after one minute.
Immediately after the length of the rectangular piece has been measured, the force is removed and the piece is laid down flat on a table for 5 minutes (at 25° C.) to be able to recover. Immediately after 5 minutes, the length of the piece is measured again and the degree of elongation is calculated by subtracting the initial length (25.4 cm) from the length after 5 minutes.
The elongation after one minute while the force has been is compared to the elongation after the piece has been laid down flat on a table for 5 minutes: If the elongation does not recover by more than 20%, the material or element is considered to be “non-elastic”.
“Highly non-elastic” as used herein refers to a material or element, which is either “non-extensible” or which does not recover by more than 10% if subjected to the test set out above for “non-elastic”.
A “nonwoven web” is a manufactured sheet or web of directionally or randomly orientated fibers, bonded by friction, and/or cohesion and/or adhesion, excluding paper and products which are woven, knitted, tufted, stitch-bonded incorporating binding yarns or filaments, or felted by wet-milling, whether or not additionally needled. The fibers may be of natural or man-made origin and may be staple or continuous filaments or be formed in situ. Commercially available fibers have diameters ranging from less than about 0.001 mm to more than about 0.2 mm and they come in several different forms such as short fibers (known as staple, or chopped), continuous single fibers (filaments or monofilaments), untwisted bundles of continuous filaments, and twisted bundles of continuous filaments (yarn). Nonwoven webs can be formed by many processes such as meltblowing, spunbonding, solvent spinning, electrospinning, carding and airlaying. Nonwoven webs may be bonded by heat and/or pressure or may be adhesively bonded. Bonding may be limited to certain areas of the nonwoven web (point bonding). Nonwoven webs may also be hydro-entangled or needle-punched. The basis weight of nonwoven webs is usually expressed in grams per square meter (gsm).
“Superabsorbent polymer particles” as used herein refers to substantially water-insoluble polymer particles that can absorb at least 5 times their weight of an aqueous 0.9% saline solution as measured using the Centrifuge Retention Capacity test (Edana 441.2-01). “Superabsorbent polymer particles” refer to an absorbent polymer material which is in particulate form so as to be flowable in the dry state.
Disposable Diaper
The chassis 12 of the disposable diaper 10 in
The leg cuffs 24 and the elastic waist feature 26 may each typically comprise elastic members 28 such as elastic strands. One end portion of the disposable diaper 10 is configured as a front waist region 30 of the disposable diaper 10. An opposite end portion of the disposable diaper 10 is configured as a back waist region 32 of the disposable diaper 10. An intermediate portion of the disposable diaper 10 is configured as a crotch region 34, which extends longitudinally between the first and second waist regions 30 and 32. The waist regions 30 and 32 may include elastic elements such that they gather about the waist of the wearer to provide improved fit and containment (elastic waist feature 26). The crotch region 34 is that portion of the disposable diaper 10 which, when the disposable diaper 10 is worn, is generally positioned between the wearer's legs.
The disposable diaper 10 is depicted in
In order to keep the disposable diaper 10 in place about the wearer, at least a portion of the first waist region 30 may be attached by the fastening member 46 to at least a portion of the second waist region 32 to form leg opening(s) and an article waist. To this end, according to certain embodiments, the disposable diaper 10 may be provided with a re-closable fastening system or may alternatively be provided in the form of a disposable diaper-pant. When the absorbent article is a disposable diaper, it may comprise a re-closable fastening system joined to the chassis for securing the disposable diaper to a wearer. The fastening system may include at least one fastening member 46 and at least one landing zone 48. When the absorbent article is a disposable diaper-pant, the article may comprise two side panels on each waist region 30, 32 joined to the chassis along the longitudinal edges of the side panels which face towards the longitudinal axis 36. The side panels of the front waist region 30 are further joined to the respective side panels of the back waist region 32 along their longitudinal edges facing away from the longitudinal axis 36 to form a pant.
A cross section of
The acquisition system 50 may comprise a single layer or multiple layers (not shown), such as an upper acquisition layer facing towards the wearer and a lower acquisition layer facing the garment of the wearer. According to a certain embodiment, the acquisition system 50 may function to receive a surge of liquid, such as a gush of urine. In other words, the acquisition system 50 may serve as a temporary reservoir for liquid until the absorbent core 14 can absorb the liquid.
In a certain embodiment, the acquisition system 50 may comprise chemically cross-linked cellulose fibers and/or nonwoven webs.
Absorbent Core
The absorbent core of the present disclosure has a longitudinal direction with a longitudinal axis and perpendicular thereto a lateral direction with a transverse axis. The longitudinal axis is substantially parallel to the longitudinal axis of the disposable diaper and the lateral direction is substantially parallel to the transverse axis of the disposable diaper. The absorbent core further has a front region, a back region and a crotch region therein between and a front lateral edge, an opposing back lateral edge, and longitudinally extending side edges. The absorbent core may comprise a first, lower and a second, upper carrier substrate, and superabsorbent polymer particles placed onto the first carrier substrate or between the first and second carrier substrate. The superabsorbent polymer particles are immobilized by a first core adhesive.
The front zone of the absorbent core represents one third of the absorbent core extending from the front edge of the absorbent core along the longitudinal axis towards the crotch region. The front zone is placed towards the front waist edge of the disposable diaper. The back zone represents one third of the absorbent core extending from the back edge along the longitudinal axis towards the crotch region. The back zone is placed towards the back waist edge of the disposable diaper. The crotch zone represents the remaining third of the absorbent core and extending between the front zone and the back zone. The complete length of the absorbent core is defined as longest extension of the absorbent core along or parallel to the longitudinal axis of the absorbent core. The absorbent core of the present disclosure may be rectangular. In one embodiment, the crotch region of the laminate absorbent core has a narrower width than the front and back regions of the absorbent core, while the front and back edge of the absorbent core still form a straight line.
In one embodiment superabsorbent polymer particles 66 are disposed on the first carrier substrate 64, and the first core adhesive 94 is disposed on the superabsorbent polymer particles 66. Typically the first core adhesive 94 is a hot melt adhesive. In one embodiment the first core adhesive 94 forms a fibrous layer which is at least partially in contact with the superabsorbent polymer particles 66 and partially in contact with the first carrier substrate 64. A second core adhesive (not shown) may be deposited on the first carrier substrate 64 before the application of the superabsorbent polymer particles 66 for enhancing adhesion of the superabsorbent polymer particles 66 and/or of the first core adhesive 94 to the first carrier substrate 64.
The first carrier substrate 64 may be dimensioned such that, after the superabsorbent polymer particles 66 and the first 94 have been applied, the first carrier substrate 64 is folded over onto itself with the superabsorbent polymer particles 66 and the first core adhesive 94 facing inwardly and the first carrier substrate 64 surrounding the superabsorbent polymer particles 66 and the first core adhesive 94. The area of the first carrier substrate 64, which is folded over, may be free of superabsorbent polymer particles 66 and the first core adhesive 94 prior to being folded over. Alternatively, the area of the first carrier substrate 64, which is folded over, may also comprise superabsorbent polymer particles 66 and a first core adhesive, such that upon folding, the two layers of superabsorbent polymer particles 66 are overlaying each other, with the first core adhesive being sandwiched between the two layers of superabsorbent polymer particles. The superabsorbent polymer particles 66 may be applied in clusters to form land areas 92 and junction areas 96 as is explained below in more detail. Also, the first core adhesive 94 may only be applied to those areas, where the first carrier substrate 64 is folded over. Upon folding, the first core adhesive 94 will also come into contact with the superabsorbent polymer particles 66 of the area, which is not folded over, thus immobilizing the superabsorbent polymer particles 66 of this area.
Alternatively to folding the first carrier substrate 64 over, the absorbent core 14 may also include a second carrier substrate 72. In still another embodiment, the absorbent core may not comprise a second carrier substrate. In this embodiment, the components of the disposable diaper 10 being placed on top of the absorbent core 14 are in direct contact with the superabsorbent polymer particles 66 and the first core adhesive 94.
The first carrier substrate 64, in use of the disposable diaper 10, is facing towards the garment of the wearer and the optional second carrier substrate 72, in use of the disposable diaper, is facing towards the wearer. The optional second carrier substrate 72 may be a nonwoven web or may, alternatively, be a tissue. The first carrier substrate 64 may be a nonwoven web, or may, alternatively be a tissue or a film. The first and second carrier substrate 64, 72 may be made of the same material or they may be made of different material. In embodiments wherein the first and second carrier substrate 64, 72 are both nonwoven webs, these nonwoven webs may be the same nonwoven webs ore they may differ from each other, e.g. with regard to their basis weight, hydrophilicity, air permeability or number and/or type of layers comprised by the nonwoven webs. The type of layers may be spunbonded layers or meltblown layers. The nonwoven webs may also be carded webs made of staple fibers, and the carded webs may or may not comprise binder material. The nonwoven webs may also be hydro-entangled or needle-punched.
The absorbent core 14 may be substantially free of airfelt. The absorbent core 14 typically comprises less than 5% by weight of airfelt, more typically less than 2% by weight and most typically is airfelt free. The absorbent core may not include an acquisition system 50, a topsheet 18, or a backsheet 20 of the disposable diaper 10. In one embodiment, the absorbent core 14 would consist essentially of the first and optional second carrier substrate 64, 72, the superabsorbent polymer particles 66, the first core adhesive 94, and optionally the second core adhesive. “Consist essentially of” in this respect means that these components make up at least 98% by weight of the absorbent core, alternatively at least 99% by weight.
The superabsorbent polymer particles 66 may be substantially continuously distributed within the superabsorbent polymer particles area of the absorbent core 14. “Superabsorbent polymer particle area” as used herein refers to the area (on the wearer facing surface) of the absorbent core which is comprises superabsorbent polymer particles. The areas adjacent the longitudinal side edges and the areas adjacent to the front and back lateral edges of the absorbent core may be free of superabsorbent polymer particles to allow for attaching the edges of the first carrier substrate 64 to the edges of the optional second carrier substrate 72 (or, in the absence of a second carrier substrate 64, the edges of the first carrier substrate may be attached to a layer above the absorbent core 14, such as a layer of the acquisition system 50). Also, the absorbent core 14 may comprise channels, i.e. areas which are substantially free of superabsorbent polymer particles 66 and which are not provided adjacent the edges of the absorbent core 14 but in some other location. “Substantially free of superabsorbent polymer particles”, as used herein, means that e.g. due to process-related reasons, a small, negligible amount of superabsorbent polymer particles may be present in the gaps, which however does not contribute to the overall functionality. The term “substantially free of superabsorbent polymer particles” encompasses “free of superabsorbent polymer particles”. However, for the present disclosure, the “superabsorbent polymer particle area” comprises at least 80% of the surface area of the absorbent core, alternatively at least 85% or at least 90%.
“Substantially continuously distributed” as used herein means that within the superabsorbent polymer particle area, the first carrier substrate 64 and optional second carrier substrate 72 (or the first substrate and the layer provided on top of the absorbent core 14 towards the wearer, such as a layer of the acquisition system 50) are separated by a multiplicity of superabsorbent polymer particles 66. It is recognized that there may be minor incidental contact areas between the first carrier substrate 64 and second carrier substrate 72 (or the first carrier substrate 64 and the component provided on top of the absorbent core 14 towards the wearer, such as the acquisition system 50) within the superabsorbent polymer particle area. Such incidental contact areas are due to unintentional manufacturing artifacts.
The absorbent core of the present disclosure may comprise—or may consist of—two layers. A first absorbent core layer 60 is shown in
In embodiments having a first and a second absorbent core layer, the first absorbent core layer 60 may comprise the first carrier substrate 64 and a first layer of superabsorbent polymer particles 66, wherein the superabsorbent polymer particles 66 are immobilized by a first core adhesive 94. Optionally, the first absorbent core layer 60 may comprise a second core adhesive (not shown). A second core adhesive may be deposited on the first carrier substrate 64 before the application of the superabsorbent polymer particles 66 for enhancing adhesion of the superabsorbent polymer particles 66 and/or of the first core adhesive 94 to the first carrier substrate 64. The first core adhesive 94 may be applied on the superabsorbent polymer particle layer as a fibrous layer, such that a fibrous network is formed.
The second absorbent core layer 62 of such embodiments comprises a second carrier substrate 72 and a second layer of superabsorbent polymer particles 66, wherein the superabsorbent polymer particles 66 may be immobilized by a first core adhesive 94. Optionally, the second absorbent core layer 62 may comprise a second core adhesive (not shown). A second core adhesive may be deposited on the second carrier substrate 72 before the application of the superabsorbent polymer particles 66 for enhancing adhesion of the superabsorbent polymer particles 66 and/or of the first core adhesive 94 to the second carrier substrate 72. The first core adhesive 94 may be applied on the superabsorbent polymer particle layer as a fibrous layer, such that a fibrous network is formed.
Once the first and second absorbent core layer 60, 62 is formed, the two absorbent core layers are combined with their respective carrier substrates 64, 72 facing outwardly and sandwiching the superabsorbent polymer particles 66 between them to form the absorbent core 14.
In one embodiment, a further substrate (not shown), such as a tissue or nonwoven web is positioned in between the first and second absorbent core layer. However, it is desired that no such substrates are positioned between the first and second absorbent core layer and that the first layer of superabsorbent polymer particles is separated from the second layer of superabsorbent polymer particles only the a fibrous layer of first core adhesive.
By applying the first core adhesive 94 as a fibrous layer, the first core adhesive 94 entangles the superabsorbent polymer particles 66, and thereby immobilizes the particles. In a further aspect, the first core adhesive 94 bonds to the carrier substrate 64 and thus affixes the superabsorbent polymer particles 66 to the carrier substrate 64. In another embodiment, the first core adhesive 68 may also penetrate to a certain extent into the carrier substrate 64, thus providing for further immobilization and affixation.
As already explained above, the first and second carrier substrates 64 and 72 may be adhered to one another with adhesive about the periphery to form an envelope about the superabsorbent polymer particles 66 to hold the superabsorbent polymer particles 66 within the absorbent core 14.
As best seen in
The first and second absorbent core layers 60 and 62 may be combined together to form the absorbent core 14 with the absorbent core layers being offset such that the superabsorbent polymer particles 66 on the first carrier substrate 64 and the superabsorbent polymer particles 66 on the second carrier substrate 72 taken in combination are substantially continuously distributed across the superabsorbent polymer particle area. In a certain embodiment, the superabsorbent polymer particles 66 are substantially continuously distributed across the superabsorbent polymer particle area while the superabsorbent polymer particles 66 of the respective first and second absorbent core layer alone are discontinuously distributed across the first and second carrier substrates 64 and 72 in clusters 90. In a certain embodiment, the absorbent core layers may be offset such that the land areas 92 of the first absorbent core layer 60 face the junction areas 96 of the second absorbent core layer 62 and the land areas 92 of the second absorbent core layer 62 face the junction areas 96 of the first absorbent core layer 60. When the land areas 92 and junction areas 96 are appropriately sized and arranged, the resulting combination of superabsorbent polymer particles 66 are a substantially continuous layer of superabsorbent polymer particles across the superabsorbent polymer particle area of the absorbent core 14.
According to the present disclosure, the superabsorbent polymer particles is typically present in an amount greater than about 85% by weight of the absorbent core, or greater than about 90% by weight of the absorbent core, or greater than about 95% by weight of the absorbent core. Also, the superabsorbent polymer particles may present more than 95% of the absorbent material comprised by the absorbent core. The absorbent core may comprise less than 5% of airfelt (i.e. cellulose fibers). Typical absorbent materials are superabsorbent polymer particles, airfelt (i.e. cellulose fibers) and—less frequently used—absorbent foams. Typically, the absorbent core comprises from 50 g/m2 to 2200 g/m2 of the superabsorbent polymer particles, from 100 g/m2 to 1500 g/m2 or even from 200 g/m2 to 1200 g/m2.
According to the present disclosure, the amount of superabsorbent polymer particles may or may not vary along the length of the absorbent core, typically the absorbent core being profiled in its longitudinal direction. It has been found that, for disposable diapers, the liquid discharge occurs predominately in the front half of the disposable diaper. The front half of the absorbent core 14 should therefore comprise most of the absorbent capacity of the absorbent core. Thus, the front half of the absorbent core 14 may comprise more than about 60% by weight of the total amount of superabsorbent polymer particles comprised by the absorbent core, or more than about 65% by weight, 70% by weight, 75% by weight, 80% by weight, 85% by weight, or 90% by weight of the superabsorbent polymer particles.
Typically the first core adhesive may serve to at least partially immobilize the superabsorbent polymer particles both in dry and wet state. The first core adhesive can be disposed essentially uniformly within the absorbent particulate polymer particles between the superabsorbent polymer particles. However, typically the first core adhesive 94 may be provided as a fibrous layer which is at least partially in contact with the superabsorbent polymer particles 66 and partially in contact with the first carrier substrate 64 and—if present—the optional second carrier substrate 72. Typically, the first core adhesive 94 forms a fibrous network over the superabsorbent polymer particles 66 of each absorbent core layer. As for example illustrated in
The first core adhesive may 94 provide cavities to cover the superabsorbent polymer particles, and thereby immobilizes this material. In a further aspect, the first core adhesive bonds to the carrier substrate(s) and thus affixes the superabsorbent polymer particles to the carrier substrate(s). Of course, while the first core adhesives disclosed herein provide an improved wet immobilization (i.e., immobilization of superabsorbent polymer particles when the disposable diaper and thus the absorbent core at least partially is wetted), these first core adhesives may also provide a good immobilization of superabsorbent polymer particles when the absorbent core is dry.
Superabsorbent Polymer Particles
The superabsorbent polymer particles may be of numerous shapes. The term “particles” refers to granules, fibers, flakes, spheres, powders, platelets and other shapes and forms known to persons skilled in the art of superabsorbent polymer particles. E.g. the particles can be in the form of granules or beads, having a particle size from about 10 μm to about 1000 μm, alternatively from about 100 μm to about 1000 μm, alternatively from about 150 μm to about 850 μm and alternatively from about 150 μm to about 500 μm. In another embodiment, the superabsorbent polymer particles can be in the shape of fibers, i.e. elongated, acicular superabsorbent polymer particles. In those embodiments, the superabsorbent polymer fibers have a minor dimension (i.e. diameter of the fiber) of less than about 1 mm, usually less than about 500 μm, and alternatively less than 250 μm down to 50 μm. The length of the fibers may be about 3 mm to about 100 mm. The fibers can also be in the form of a long filament that can be woven.
Some superabsorbent polymer particles of the present disclosure are spherical-like particles. According to the present disclosure and in contrast to fibers, “spherical-like particles” have a longest and a smallest dimension with a particulate ratio of longest to smallest particle dimension in the range of 1-5, where a value of 1 would equate a perfectly spherical particle and 5 would allow for some deviation from such a spherical particle.
The superabsorbent polymer particle materials useful in the present disclosure include a variety of water-insoluble, but water-swellable polymers capable of absorbing large quantities of fluids. Such polymers materials are generally known in the art and include all those well-known polymers used or deemed useful in the context of disposable absorbent article technology.
Example polymer materials for use in making superabsorbent polymer particles are slightly network cross linked polymers of partially neutralized polyacrylic acids and starch derivatives thereof. Starch-based superabsorbent polymer particles are also encompassed in the present disclosure. The superabsorbent polymer particles may comprise from 25% to 95% by weight, alternatively from 50% to 80% by weight neutralized, slightly network cross-linked, polyacrylic acid. Network cross-linking renders the polymer substantially water-insoluble and, in part, determines the absorptive capacity and extractable polymer content characteristics of the superabsorbent polymer particles.
While the superabsorbent polymer particles may be of one type (i.e., homogeneous), mixtures of polymers can also be used in the present disclosure. The superabsorbent polymer particles can also comprise mixtures with low levels of one or more additives, such as for example powdered silica, surfactants, adhesive, binders, and the like. Furthermore, the superabsorbent polymer particles can comprise a gradient in particle size or can comprise a certain range of particle size.
Many of the formerly known superabsorbent polymer particles exhibited gel blocking “Gel blocking” occurs when particles made of the superabsorbent polymer materials are wetted and the particles swell so as to inhibit fluid transmission to other zones or regions of the absorbent structure. Wetting of these other regions of the absorbent core therefore takes place via a very slow diffusion process. In practical terms, this means acquisition of fluids by the absorbent structure is much slower than the rate at which fluids are discharged, especially in gush situations. Leakage from the disposable diaper can take place well before the superabsorbent polymer particles in the absorbent core are even close to being fully saturated or before the fluid can diffuse or wick past the “blocking” particles into the rest of the absorbent core.
One commonly applied way to reduce gel blocking is to make the particles stiffer, which enables the superabsorbent polymer particles to retain their original shape thus creating or maintaining void spaces between the particles. A well-known method to increase stiffness is to covalently and/or ionically cross-link the carboxyl groups exposed on the surface of the superabsorbent polymer particles. This method is commonly referred to as surface cross-linking
First and Second Core Adhesive
The first and optional second core adhesive comprised by the absorbent core may be a hot melt adhesive. In certain embodiments, the first core adhesive is a hot melt adhesive whereas the second core adhesive may be another type of adhesive. The average basis weight of first plus optional second core adhesive in the absorbent core may be from 0.5 g/m2 to 30 g/m2, between 1 g/m2 to 15 g/m2, between 1 g/m2 and 10 g/m2 or even between 1.5 g/m2 and 5 g/m2.
The first core adhesive serves to at least partially immobilize the superabsorbent polymer particles of the absorbent core, both in dry and wet condition.
Without wishing to be bound by theory, it has been found that those hot melt adhesives which are most useful for immobilizing the superabsorbent polymer particles combine good cohesion and good adhesion behavior. Good adhesion may promote good contact between the hot melt adhesive and the superabsorbent polymer particles and the carrier substrates. Good cohesion reduces the likelihood that the adhesive breaks, in particular in response to external forces, and namely in response to strain. When the absorbent core absorbs liquid, the superabsorbent polymer particles swells and subjects the hot melt adhesive to external forces. The hot melt adhesive may allow for such swelling, without breaking and without imparting too many compressive forces, which would restrain the absorbent particulate polymer particles from swelling.
In accordance with present disclosure the hot melt adhesive may comprise, in its entirety, a single thermoplastic polymer or a blend of thermoplastic polymers, having a softening point, as determined by the ASTM Method D-36-95 “Ring and Ball”, in the range between 50° C. and 300° C., or alternatively the hot melt adhesive may comprise at least one thermoplastic polymer in combination with other thermoplastic diluents such as tackifying resins, plasticizers and additives such as antioxidants.
In certain embodiments, the thermoplastic polymer typically has a weight average molecular weight (Mw) of more than 10,000 and a glass transition temperature (Tg) usually below room temperature (25° C.), or of less than 22° C., or less than 18° C., or less than 15° C. In certain embodiments Tg may be above 0° C.>Tg. In embodiments where the thermoplastic polymer has more than one Tg the values given refer to the lowest glass transition temperature. The thermoplastic polymer may also have a softening point, as determined by the ASTM Method D-36-95 “Ring and Ball”, in the range between 50° C. and 300° C. In some embodiments the Mw of the thermoplastic polymer is less than 10000000.
In certain embodiments, typical concentrations of the thermoplastic polymer in a hot melt adhesive are in the range of about 20% to about 40% by weight of the hot melt adhesive.
Exemplary polymers are (styrenic) block copolymers including A-B-A triblock structures, A-B diblock structures and (A-B)n radial block copolymer structures wherein the A blocks are non-elastomeric polymer blocks, typically comprising polystyrene, and the B blocks are unsaturated conjugated diene or (partly) hydrogenated versions of such. The B block is typically isoprene, butadiene, ethylene/butylene (hydrogenated butadiene), ethylene/propylene (hydrogenated isoprene), and mixtures thereof.
Other suitable thermoplastic polymers that may be employed are metallocene polyolefins, which are ethylene polymers prepared using single-site or metallocene catalysts. Therein, at least one comonomer can be polymerized with ethylene to make a copolymer, terpolymer or higher order polymer. Also applicable are amorphous polyolefins or amorphous polyalphaolefins (APAO) which are homopolymers, copolymers or terpolymers of C2 to C8 alpha olefins.
In exemplary embodiments, the tackifying resin has typically a Mw below 5,000 and a Tg usually above room temperature (25° C.), typical concentrations of the tackifying resin in a hot melt are in the range of about 30% to about 60% by weight of the hot melt adhesive. In certain embodiments the tackifying resin has an Mw of more than 1,000.
The plasticizer has a low Mw of typically less than 1,000 and a Tg below room temperature, with a typical concentration of about 0% to about 15% by weight of the hot melt adhesive. In certain embodiments the plasticizer has an Mw of more than 100.
In certain embodiments, the first and/or second core adhesive is hot melt adhesive present in the form of fibers. In some embodiments, the fibers will have an average thickness of about 1 to about 50 micrometers or about 1 to about 35 micrometers and an average length of about 5 mm to about 50 mm or about 5 mm to about 30 mm.
The absorbent core may also comprise a second core adhesive which is not illustrated in the figures. The second core adhesive may be deposited on the carrier substrate before application of the superabsorbent polymer particles on the carrier substrate for enhancing adhesion of the superabsorbent polymer particles and the first core adhesive to the respective carrier substrate. The second core adhesive may also aid in immobilizing the superabsorbent polymer particles and may be the same adhesive as the first core adhesive or may be different from the first core adhesive. The second core adhesive may also be a hot melt adhesive. An example of commercially available second core adhesive is H. B. Fuller Co. (St. Paul, Minn.) Product No. HL-1620-B. The second core adhesive may be applied to the carrier substrate(s) by any suitable means, but according to certain embodiments, may be applied in about 0.5 to about 1 mm wide slots spaced about 0.5 to about 2 mm apart.
Attachment of Absorbent Core to Backsheet
If a disposable diaper is applied onto a wearer, the disposable diaper will take a curved shape in order to conform to the wearer (i.e. the diaper will not be flattened out but will be bent with the front and back waist regions of the diaper lying against the waist of the wearer and the crotch region of the diaper being placed against the crotch region of the wearer). Moreover, the diaper is subjected to a certain degree of bending along lines which are substantially parallel to the longitudinal axis of the diaper between the wearer legs and towards the front waist region. Such bending results in buckling of the diaper, i.e. the diaper is bulged outwardly in the crotch region and in at least parts of the front waist region.
Upon applying the disposable diaper onto a wearer by bending it, the surface areas of the disposable diaper is altered as follows versus a flattened out diaper: While the upper, wearer-facing surface (i.e. the topsheet) is upset and upended, the lower, garment-facing surface (i.e. the backsheet) is elongated. The same applies for the absorbent core within the disposable diaper: The upper, wearer-facing surface (such as the second, upper carrier substrate) is upset and upended while the lower, garment-facing surface (such as the first, lower carrier substrate) is elongated.
In the vast majority of disposable diapers on the market today, the absorbent core comprises a considerable amount of cellulose fibers (airfelt). The superabsorbent polymer particles comprised in these absorbent cores are mixed with the cellulose fibers and the particles are thus held in place in the interstices between the cellulose fibers. Generally, no adhesive is used to immobilize the superabsorbent polymer particles. Overall, these absorbent cores have a rather plastic characteristic. If such diapers undergo the bending described above when the disposable diaper is applied onto a wearer, the material within the absorbent core is able to compensate at least some of the upending of the upper surface and the elongation of the lower surface by migration of cellulose fibers and superabsorbent polymer particles within the core.
Also, when the disposable diaper gets wetted and the superabsorbent polymer particles swell and expand, the superabsorbent polymer particles can to a certain extent swell within the interstices of the cellulose fibers. Hence, the volume increase of the absorbent core as a whole is less than the volume increase of the superabsorbent polymer particles because the dry absorbent core provides some free space into which the particles can expand.
In an absorbent core of the present disclosure, which comprises little or no airfelt and wherein the superabsorbent polymer particles are immobilized by an adhesive, the absorbent core has a much more elastic characteristic compared to the conventional absorbent core described above. As the superabsorbent polymer particles are immobilized much stronger than superabsorbent polymer particles which are simply mixed within a cellulose fiber matrix, the superabsorbent polymer particles cannot migrate within the absorbent core when the disposable diaper is applied onto a wearer. Therefore, the buckling of the upper, wearer-facing surface as well as the elongation of the lower, garment-facing surface is much more pronounced as in conventional, airfelt-containing disposable diapers.
Also, as the disposable diaper is wetted, the superabsorbent polymer particles swell and expand. Contrary to a conventional, airfelt-containing absorbent core, an absorbent core having little or no airfelt may not provide any “free space” in the interstices between the cellulose fibers, into which the superabsorbent polymer particles can expand. Thus, the absorbent core as a whole will expand and swell much earlier (i.e. much longer before the absorption capacity limit of the absorbent core is reached) and will expand much more compared to a conventional absorbent core. Such expansion increases the strain applied onto the lower, garment-facing surface (such as the lower carrier substrate) of the absorbent core and, in turn, increases the strain applied onto the backsheet. Consequently, the lower, garment-facing surface of the absorbent core as well as the backsheet will elongate further upon wetting of the diaper.
As a consequence of the elongation of the wearer-facing surface, the absorbent core is firmly pressed against the backsheet of the disposable diaper. Upon absorption of urine and runny feces, the absorbent core is stained and, due to the dense contact between the absorbent core and the backsheet, the staining may be visible through the backsheet, especially if the basis weight of the backsheet material is low and/or if the backsheet has a little or no printing. This see-through of stains has a negative impact on consumer acceptance of the disposable diaper, as it is perceived as low quality. Moreover, the see-through is often interpreted as indicating wet-through, i.e. the absorbent core is perceived as being soaked with liquid, signaling that the absorbent core has reached its capacity maximum—even if in fact the diaper is far from reaching its maximum capacity. Also the backsheet may be perceived as being wet upon visual inspection of the disposable diaper.
Furthermore, upon elongation and straining of the backsheet, the backsheet tends to buckle and form wrinkles and tension lines. These tension lines and wrinkles are interpreted by consumers as signals that the absorbent capacity of the disposable diaper is exhausted and the diaper needs to be changed. This effect may occur long before the actual capacity limit of the diaper is reached.
The inventors have found that the above explained disadvantages can be reduced if the attachment of absorbent core to backsheet is altered: In conventional, airfelt-containing disposable diapers as well as in commercially available disposable diapers having little or no airfelt (e.g. Pampers “Active Fit” sold in Germany in May 2011), the absorbent core is adhesively attached to the backsheet over the complete garment-facing surface of the absorbent core (hence, e.g. the first carrier substrate of the absorbent core). This does not necessarily mean that 100% of the surface area of the carrier substrate are covered with adhesive but it may be that the adhesive, such as hot melt adhesive, is applied in small spirals and these spirals are applied all over the carrier substrate.
If the absorbent core is adhesively attached to the backsheet over essentially the whole area of the absorbent core, the absorbent core cannot move and expand independently from the backsheet. Consequently, as the absorbent core expands upon swelling of the superabsorbent polymer particles, the backsheet will also have to expand.
It has been found that this drawback can be reduced if the absorbent core is not attached to the backsheet over the whole absorbent core surface. If the absorbent core is attached to the backsheet only in certain, limited areas, and if these areas are carefully and meaningfully chosen, the formation of buckles and wrinkles in the backsheet can be reduced. Also, see-through of urine stains from the absorbent core through the backsheet can be reduced.
According to the present disclosure, the absorbent core is attached to the backsheet in any of the following locations:
If the absorbent core is attached to the backsheet according to option a), the attachment zones adjacent the front lateral edge and the back lateral edge of the absorbent core may be provided only in the corners of the absorbent core, leaving the remaining area adjacent the front lateral edge and the back lateral edge of the absorbent core unattached to the backsheet. The “remaining area” refers to 70%, or 80% of the width of the absorbent core in the area adjacent to the front and back lateral edges. The one or more attachment zone(s) of option a) or d) may cover from 0.2% to 3%, alternatively from 0.5% to 2%, or from 0.5% to 1.5%, or from 0.2% to 1.5% or from 0.2% to 1% of the total surface area of the absorbent core. These percentages refer to the totality of all attachment zones taken together.
In embodiments according to option a), the absorbent core may be attached to the backsheet in one attachment zone adjacent to the front lateral edge and in one attachment zone adjacent to the back lateral edge of the absorbent core and may be unattached to the backsheet in any other region. Alternatively, the absorbent core may be attached to the backsheet in two, three or more attachment zones adjacent to the front lateral edge and in two, three or more attachment zones adjacent to the back lateral edge of the absorbent core and may be unattached to the backsheet in any other region. In still another alternative, the absorbent core may be attached to the backsheet in one attachment zone adjacent to the front lateral edge of the absorbent core and in two, three or more attachment zones adjacent to the back lateral edge and be unattached to the backsheet in any other region; or may be attached to the backsheet in two, three or more attachment zones adjacent to the front lateral edge of the absorbent core and in one attachment zone adjacent to the back lateral edge and be unattached to the backsheet in any other region.
In embodiments according to option c), the absorbent core may be attached to the backsheet in one attachment zone adjacent to one longitudinal side edge and in one attachment zone adjacent to the respective other longitudinal side edge and may be unattached to the backsheet in any other region. Alternatively, the absorbent core may be attached to the backsheet in two, three or more attachment zones adjacent to one longitudinal side edge and in two, three or more attachment zones adjacent to the respective other longitudinal side edge of the absorbent core and may be unattached to the backsheet in any other region. In still another alternative, the absorbent core may be attached to the backsheet in one attachment zone adjacent to one longitudinal side edge of the absorbent core and in two, three or more attachment zones adjacent to the respective other longitudinal side edge and be unattached to the backsheet in any other region.
If the absorbent core is attached to the backsheet according to option b), the one or more attachment zone(s) in the crotch region may have a longitudinal direction substantially parallel to the longitudinal direction of the absorbent core and may have a lateral direction substantially parallel to the lateral direction of the absorbent core. The ratio between longitudinal direction and lateral direction of the one or more attachment zone(s) may be from 0.5 to 2.0, or from 2.0 to 0.5, or from 0.5 to 1.0, or from 1.0 to 0.5. The one or more attachment zone(s) of option b) cover from 0.2% to 3%, alternatively from 0.5% to 2%, or from 0.5% to 1.5%, or from 0.2% to 1.5% or from 0.2% to 1% of the total surface area of the absorbent core. These percentages refer to the totality of all attachment zones taken together. Also, if the absorbent core is attached to the backsheet according to option b), the disposable diaper may further comprise a wetness indicator with the wetness indicator being placed between the absorbent core and the backsheet in at least one of the one or more attachment zone(s) in the crotch region of the absorbent core on or adjacent to the longitudinal axis of the absorbent core.
The term “adjacent to the front lateral edge and the back lateral edge of the absorbent core”, as used herein, means a distance of less than 15%, or less than 10%, or less than 5% (based on the total length of the absorbent core) inwardly, starting from the front lateral edge (for attachment zone(s) adjacent to the front lateral edge) and back lateral edge (for attachment zone(s) adjacent to the back lateral edge), respectively, and extending along or parallel to the longitudinal axis of the absorbent core towards the crotch zone.
The term “adjacent to the longitudinal axis of the absorbent core”, as used herein, means that the attachment zone is either on the longitudinal axis or is at a distance of less than 15%, or less than 10%, or less than 5% (based on the total width of the absorbent core) away from the longitudinal axis towards the left or right longitudinal side edge. For embodiments having more than one attachment zone adjacent to the longitudinal axis of the absorbent core, the attachment zones may be at a distance of less than 15%, or less than 10%, or less than 5% (based on the total width of the absorbent core) away from the longitudinal axis towards the left and right longitudinal side edge.
The term “adjacent to the longitudinal side edges of the absorbent core” as used herein, means a distance of less than 15%, or less than 10%, or less than 5% (based on the total width of the absorbent core) inwardly, starting from the left and right longitudinal edge, respectively, and extending along or parallel to the transverse axis of the absorbent core towards the crotch zone.
The total surface area of the absorbent core is defined by the x- and y-dimension of the absorbent core. Any potential unevenness of the surface and irregularities of thickness (i.e. in the z-direction) is not taken into account. The x-,y-dimension of the absorbent core is determined while the absorbent core is lying flat on a table with not stress or strain applied (this also applies for potentially extensible absorbent cores). If needed, elastically contracting elements that otherwise would apply strain to the absorbent core can be carefully removed prior to lying the absorbent core flat on a table.
Attaching the absorbent core to the backsheet according to any of options a) to d) above, the absorbent core, while expanding upon liquid absorption, may slide relative to the backsheet, thus the absorbent core may expand largely independently from the backsheet and not forcing the backsheet to expand together with the absorbent core. Hence, the formation of wrinkles and tension lines in the backsheet can be reduced. Also, see-through of urine strains through the backsheet can be reduced (as the absorbent core is not held as closely against the backsheet as in embodiments where the absorbent core is attached to the backsheet over the whole absorbent core area). This is believed to be due to the formation of a small air-cushion between the absorbent core and the backsheet, which cannot be formed in areas, where the absorbent core is closely attached (e.g. by adhesive) to the backsheet. To reduce see-through, a very small air-cushion is believed to be sufficient. For visualizing the reduction of see-through, the test method set out below can be used. This test method allows a qualitative visualization with the naked eye (i.e. without the need for microscope or the like).
In the disposable diapers of the present disclosure, the topsheet may be sealed to the backsheet along the perimeter of the topsheet and backsheet, i.e. outside the areas, where the absorbent core is encased between the topsheet and backsheet. To allow the absorbent core to expand between the topsheet and backsheet, the topsheet may be sealed to the backsheet at a distance away from the perimeter of the absorbent core, especially in the transverse direction, i.e. along the longitudinal side edges of the absorbent core. The seal between the topsheet and the backsheet along the longitudinal side edges of the absorbent core may be such, that the width of the absorbent core is less than 90%, alternatively less than 85% of the width between the longitudinal side edge seals between the topsheet and the backsheet. If the width of the absorbent core and/or the width between the longitudinal side edge seals between the topsheet and the backsheet varies along the length of the disposable diaper, the width of the absorbent core may be less than 90%, alternatively less than 85% of the width between the longitudinal side edge seals between the topsheet and the backsheet at every location along the length of the disposable diaper.
Attaching the absorbent core to the backsheet in attachment zones adjacent to the front lateral edge and the back lateral edge of the absorbent core or in attachment zones adjacent to the longitudinal side edges of the absorbent core has the benefit, that the absorbent core cannot twist or even roll over in the disposable diaper, as it is held in place in more than one location. This is especially advantageous for certain manufacturing processes, where individual absorbent cores are placed onto an endless web of backsheet material (which is cut into individual backsheets only at a later stage in the manufacturing process). The topsheet is placed on top of the absorbent core only after the absorbent core has been placed onto the endless backsheet material, typically in form of an endless web of topsheet material, which is cut into individual topsheets at a later stage together with the backsheet. Hence, at a certain stage, the absorbent core is lying on top of the backsheet with no overlying components. The absorbent core, besides being attached to the endless web of backsheet material in the attachment zones, is typically held onto the backsheet by a vacuum, which is underneath the backsheet. However, at this stage, there is a risk that the absorbent core lifts from the backsheet especially in high speed manufacturing processes. Thus, attaching the absorbent core to the backsheet in more than one attachment zone, as is the case in option a), c) and d) set out above, bears a reduced risk of absorbent core lift up versus option b), wherein the absorbent core is attached to the backsheet only in one location.
However, attaching the absorbent core to the backsheet only in one location is nevertheless possible, if the manufacturing process is adapted accordingly (i.e. higher vacuum, slower speed of manufacturing line, or joining the absorbent core and the topsheet onto the backsheet at the same time.). Attaching the absorbent core to the backsheet according to option b), i.e. only in one attachment zone has the advantage that expansion of the wetted absorbent core is not hindered both parallel to the longitudinal axis and parallel to the transverse axis of the absorbent core.
Once the topsheet has been placed on top of the absorbent core, the topsheet can be sealed to the backsheet around the perimeter of the topsheet and backsheet, which can be done prior to or after cutting the endless topsheet and backsheet material into individual topsheets and backsheets. Also, the topsheet may be attached to the absorbent core once the topsheet has been put onto the absorbent core.
As see—through is reduced, the present disclosure allow using low basis weight backsheet materials. The backsheet of the disposable diaper of the present disclosure may consist of a film and optionally one or more nonwoven webs. The basis weight of the backsheet including film and optional nonwoven webs may be less than 70 g/m2, or may be from 25 g/m2 to 70 g/m2, or from 25 g/m2 to 60 g/m2 or from 25 g/m2 to 50 g/m2. The film (without nonwoven webs) may have a basis weight of less than 25 g/m2, or from 10 g/m2 to 25 g/m2, or from 10 g/m2 to 20 g/m2. The optional nonwoven webs may have a basis weight of less than 40 g/m2, or from 10 g/m2 to 30 g/m2, or from 10 g/m2 to 25 g/m2 (in embodiments having more than one nonwoven web, these values represent the sum for all nonwoven webs taken together).
Also, according to the present disclosure, the backsheet may be white and may have a printed area (with non-white colors) of less than 50%, or less than 30% in the area which is coincident with the front region and crotch region of the absorbent core.
The backsheet of the disposable diaper of the present disclosure may not be elastic. Non-elastic materials are generally less expensive compared to elastic materials and given that the absorbent core is able to expand independently from the backsheet to some extent, it is not necessary that the backsheet is elastic. Hence, the backsheet of the present disclosure may be non-elastic or highly non-elastic.
The absorbent core may be attached to the topsheet of the disposable diaper. As the topsheet is typically only attached to the backsheet at the perimeter of the topsheet and backsheet, such attachment to the topsheet will not adversely affect the advantages of the present disclosure, namely reduced see-through and reduced formation of wrinkles and tension lines in the backsheet. The absorbent core may be attached to the topsheet at least in the front region and in the crotch region of the absorbent core. The absorbent core may be directly attached to the topsheet. Alternatively, in disposable diapers having an acquisition system between the topsheet and the absorbent core, the absorbent core may be attached to the acquisition system, which in turn is attached to the topsheet. Attachment of absorbent core to the topsheet or acquisition system may be done adhesively, for example using hot melt adhesive.
Attachment of the absorbent core to the backsheet according to the present disclosure may be done with adhesive, optionally a hot melt adhesive. The attachment is directly between the absorbent core and the backsheet. If the absorbent core has a first carrier substrate, the attachment is between the garment-facing surface of the lower carrier substrate and the wearer-facing surface of the backsheet.
The absorbent core of the present disclosure may comprise one or more channels, i.e. areas which are substantially free of superabsorbent polymer particles and which are not provided adjacent the edges of the absorbent core but in some other location. “Substantially free of superabsorbent polymer particles”, as used herein, means that e.g. due to process-related reasons, a small, negligible amount of superabsorbent polymer particles may be present in the gaps, which however does not contribute to the overall functionality. The term “substantially free of superabsorbent polymer particles” encompasses “free of superabsorbent polymer particles”. The channels may be provided in the crotch region and/or in the front region of the absorbent core. The channels are elongated and may have a width to length ratio of 1 to 20, or 1 to 15, or 1 to 10, or 1 to 5, or 1 to 3. The channels may be straight or may be curved. Such channels can further help to improve the conformity of the disposable diaper, i.e. the diaper conforms better to the wearer. This can further help to reduce the tension lines and wrinkles of the backsheet discussed above. If the absorbent core comprises one or more channels, the attachment zones, where the absorbent core is attached to the backsheet, may be outside the area(s) which is (are) provided with the one or more channels. The channels may not extend onto the front and back lateral edges and longitudinal edges of the absorbent core.
The absorbent core of the present disclosure may further have a first carrier substrate, which is the substrate of the absorbent core that is lying directly on top of the backsheet. If the absorbent core comprises one or more channels, first carrier substrate may be water permeable (at 25° C. and 50% RH) (such as a tissue web or a water permeable nonwoven web). In such embodiments, a certain amount of liquid (urine) may penetrate through the complete thickness of the absorbent core and may be distributed in the space between the absorbent core and the backsheet. Thus, liquid distribution may be improved, as the liquid may spread between the absorbent core and the backsheet to other, more remote areas where it can be absorbed by the absorbent core. Taken in combination with the attachment zones of the present disclosure, where the absorbent core is attached to the backsheet and is left unattached to the backsheet in any other region, the liquid between the absorbent core and the backsheet can spread relatively unobstructed. However, in these absorbent cores, the size of the one or more channels has to be chosen carefully to ensure that the amount of liquid passing through the thickness of the absorbent core in the space between the absorbent core and the backsheet does not become too extensive.
Test Method to Visualize Backsheet See-Through
This method visualizes the see-through of stains through the backsheet of a disposable diaper. The test can be carried out with disposable diapers having different pattern and extent absorbent core attachment to backsheet to qualitatively visualize the differences. The load protocol used is for disposable diapers typically designated for wearers having a weight in the range of 8 to 13 kg±20% (such as Pampers “Active Fit”, Size 4 or other Pampers baby diapers Size 4, Huggies baby diapers Size 4 and baby diapers Size 4 of most other tradenames).
Apparatus Load Protocol
The test apparatus is shown in
A slab of open-cell polyurethane foam 114 with dimensions 508×152×25 mm is wrapped in polyethylene film and placed in the bottom of the trough 111 in such a way that the edges of the foam 114 and the trough 111 are aligned, and the upper surface of the polyethylene film is smooth and free of seams, wrinkles or imperfections. The polyurethane foam 114 has a compressive modulus of 0.48 psi. A reference line is drawn across the width of the upper surface of the polyethylene cover 152 mm (6.0 inches) from one end (the front edge) parallel to the transverse centerline using an indelible marker.
A rectilinear polycarbonate top plate 115 has a nominal thickness of 12.5 mm (0.5 inch), a length of 508 mm (20.0 inches), and a width of 146 mm (5.75 inches). A 51 mm (2.0 inch) diameter hole is bored in the center of the top plate 115 (i.e. the center of the hole is located at the intersection of the longitudinal and transverse axes of the upper surface of the top plate 115). A polycarbonate cylinder 116 with an outside diameter of 51 mm (2.0 inches), an internal diameter of 37.5 mm (1.5 inches) and a height of 102 mm (4.0 inches) is glued into the hole in the top plate 115 so that the bottom edge of the cylinder 116 is flush with the lower surface of the top plate 115 and the cylinder 116 protrudes vertically 89 mm (3.5 inches) above the upper surface of the top plate 115, and the seam between the cylinder 116 and the top plate 115 is watertight. An annular recess 117 with a height of 2 mm and a diameter of 44.5 mm (1.75 inches) is machined into the bottom internal edge of the cylinder 116. Two 1 mm diameter holes are drilled at a 45° angle to the upper surface of the top plate 115 so that the holes intersect the inner surface of the cylinder 116 immediately above the recess 117 and are at opposite sides of the cylinder 116 (i.e. 180° apart). Two stainless steel wires 118 having a diameter of 1 mm are glued into the holes in a watertight fashion so that one end of each wire is flush with the inner cylinder wall and the other end protrudes from the upper surface of the top plate 115. These wires are referred to as electrodes herein below. A reference line is scribed across the width of the top plate 115 152 mm (6.0 inches) from the front edge parallel to the transverse centerline. The top plate 1415/cylinder 116 assembly has a weight of approximately 1180 grams.
Two steel weights each weighing 0.9 Kg and measuring 127 mm (5 inches) wide, 50 mm (1.97 inches) deep, and approximately 16 mm (0.63 inches tall) are also required.
Procedure
All testing is carried out at 23±2° C. and 35±15% relative humidity.
The polycarbonate trough 111 containing the wrapped foam slab 114 is placed on a suitable flat horizontal surface. A disposable absorbent product is removed from its packaging and the cuff elastics are cut at suitable intervals to allow the product to lay flat. The product is weighed to within ±0.1 grams on a suitable top-loading balance then placed on the covered foam slab 114 in the acquisition apparatus with the front waist edge of the product aligned with the reference mark on the polyethylene cover. The product is centered along the longitudinal centerline of the apparatus with the topsheet (body-side) of the product facing upwards and the rear waist edge toward the rear end of the foam slab 114. The top plate 115 is placed on top of the product with the protruding cylinder facing upwards. The scribed reference line is aligned with the front waist edge of the product and the rear end of the top plate 115 is aligned with the rear edge of the foam slab 114. The two 0.9 Kg weights are then gently placed onto the top plate 115 so that the width of each weight is parallel to the transverse centerline of the top plate, and each weight is 83 mm (3.25 inches) from the front or rear edge of the top plate 115.
A suitable electrical circuit is connected to the two electrodes to detect the presence of an electrically conductive fluid between them.
A suitable pump; e.g. Model 7520-00 supplied by Cole Parmer Instruments, Chicago, USA, or equivalent; is set up to discharge a 0.9 mass % aqueous solution of sodium chloride through a flexible plastic tube having an internal diameter of 4.8 mm ( 3/16 inch), e.g. Tygon® R-3603 or equivalent. The 0.9% NaCl solution is stained with Indigo carmine (C16H8N2Na2O8S2) by Merck (104724 Indigocarmin C.I. 73015), using 40 mg per liter of 0.9% NaCl solution. The end portion of the tube is clamped vertically so that it is centered within the cylinder 116 attached to the top plate 115 with the discharge end of the tube facing downwards and located 50 mm (2 inches) below the upper edge of the cylinder 116. The pump is operated via a timer and is pre-calibrated to discharge a gush of 90.0 ml of the 0.9% saline solution at a rate of 15 ml/sec.
The pump is activated and a timer started immediately upon activation. The pump delivers 90 mL of 0.9% NaCl solution to the cylinder 116 at a rate of 15 ml/sec, then stops. As test fluid is introduced to the cylinder 116, it typically builds up on top of the absorbent structure to some extent. This fluid completes an electrical circuit between the two electrodes in the cylinder. After the gush has been delivered, the meniscus of the solution drops as the fluid is absorbed into the structure. When the electrical circuit is broken due to the absence of free fluid between the electrodes in the cylinder, the time is noted.
The acquisition time for a particular gush is the time interval between activation of the pump for that gush, and the point at which the electrical circuit is broken.
Four gushes are delivered to the product in this fashion; each gush is 90 ml and is delivered at 15 ml/sec. The time interval between the beginnings of each gush is 300 seconds.
