An example of such a product is the Fumakila mitt sold in Japan. The search for improved gloves and mitts for cleaning has continued.
This invention relates to cleaning articles, such as cloths, gloves, and mitts. The cleaning articles described herein are useful for cleaning various objects, including, but not limited to vehicles, such as cars.
There are numerous non-limiting embodiments of the present invention. In one non-limiting embodiment, a cleaning article is disclosed that is in the form of a glove or mitt which comprises a body portion having an opening therein. The glove or mitt is sized and configured to receive at least a portion of a human hand in the opening. The body portion comprises a first face or side that is worn or held adjacent to the front of the user's hand, and at least a partial second face or side that is worn adjacent to the back of the user's hand. The cleaning article may be provided with properties such as wet strength so that it is suitable for a wet cleaning operation, such as for washing a car by hand. In this embodiment, at least one of the first side and the second side comprises a cleaning surface comprising a three-dimensional structure. The three-dimensional structure is comprised of a plurality of strips of material that are joined to the body portion. There may be one or more layers of strips of material that are stacked on top of one another. In some embodiments, the width of at least some of the strips of material are greater than ⅛ inch (about 3 mm), or alternatively, greater than or equal to about 4.5 mm, or alternatively, greater than or equal to about 3/16 inches (about 4.8 mm).
In another non-limiting embodiment, the cleaning article has an apertured outer surface (or “topsheet”) that comprises its cleaning surface. In this embodiment, the apertured cleaning surface can comprise an apertured nonwoven fabric, or an apertured film. In this embodiment, the cleaning article may comprise a secondary component (or “secondary material”) underneath the cleaning surface. The secondary component is considered to be “underneath” the cleaning surface, when the cleaning article is oriented with its cleaning surface facing upward. The secondary component may, but need not, serve one or more of the following functions: a cushioning function; a spacing function; an absorbent function; a soil capturing function; and/or a lathering function for lathering a cleaning composition. The secondary component can comprise a number of different types of materials, including but not limited to: a batting, single or multiple layers of fibrous material or webs made by various methods or combinations of methods. Such materials may include, but are not limited to the following: air laid, carded, carded thermally bonded, hydroentangled, spunmelt, meltblown materials, and the like. The secondary component can also comprise other synthetic and/or natural based materials in other forms such as foam structures.
In another non-limiting embodiment, the cleaning article comprises a body portion having an opening therein, the body portion being sized and configured to receive at least a portion of a human hand in the opening with fingers positioned adjacent a finger area of the body portion. The body portion comprises a first side having a total surface and a second side having a total surface, wherein at least one of the first and second sides comprises a first region defining a first surface and a second region defining a second surface. The first region comprises a substantially planar material, and the first surface is less than about 90% of the total surface of the side comprising the first region. The first region is visually distinct from the second region.
In a further non-limiting embodiment, the cleaning article comprises a body portion having an opening therein, the body portion being sized and configured to receive at least a portion of the human hand in the opening with fingers positioned adjacent a finger area of the body portion. The body portion comprises a first side, a second side, and a finger positioning portion located within the finger area of the body portion and connecting the first side with the second side. The finger positioning portion defines first, second and third finger regions at least partially separated by the finger positioning portion.
The cleaning article may have a liquid (e.g., water) resistant or liquid impervious liner or backsheet. In the case of cleaning articles in the form of a glove or mitt, the liner may comprise an inner liner that at least partially lines the inside of the same. In other embodiments, at least a portion of the cleaning article may be made liquid resistant or liquid impervious in manners other than by providing the same with a liner. For example, at least a portion of the cleaning article may be made liquid resistant or liquid impervious by providing at least a portion of the materials comprising the same with an inner liquid resistant or liquid impervious coating.
In other embodiments, the cleaning article need not comprise a portion that completely covers the back of the user's hand, as in the case of a glove or mitt. In other embodiments, for example, the cleaning article can be in the form of a wipe that does not have any portions covering the back of the user's hand. In other embodiments, the cleaning article can have a portion that only covers (or is merely worn adjacent to) part of the back of the user's hand. One example of such an embodiment is one in which the cleaning article is similar in form to a wipe, but which has a portion at one end thereof into which the wearer can slip the top portions of their fingers, which only covers (or is merely worn adjacent to) part of the back of the user's hand. Such embodiments may cover, for example only: the backs of the user's fingers; the backs of the top portion of the user's fingers; or a portion of the back of the user's hand, but not all of the back of the user's hand.
The cleaning articles described herein can be of a type that is intended for a single use (disposable), or of a type intended for more than one use. Numerous other embodiments are also possible, including, but not limited to those described in the following detailed description. The present invention also includes the methods of making the cleaning articles described herein.
The present invention will become more readily apparent when considered in reference to the following description and when taken in conjunction with the accompanying drawings.
While the specification concludes with claims particularly pointing out and distinctly claiming the subject matter which is regarded as forming the present invention, it is believed that the invention will be better understood from the following description taken in conjunction with the accompanying drawings, in which:
This invention relates to cleaning articles, such as cloths, gloves, and mitts. The cleaning articles described herein are useful for cleaning various objects, including, but not limited to vehicles, such as cars. The present invention also includes the methods of making the cleaning articles described herein.
The cleaning article 20 shown in
In the embodiment shown in
The strips of material 30 can be disposed in any suitable orientation. As shown in
There can be any suitable number of strips 30, and the strips 30 can be provided in any suitable arrangement. As shown in
In the embodiment shown in
The term “joined”, as used in this specification, encompasses configurations in which an element is directly secured to another element by affixing the element directly to the other element; configurations in which the element is indirectly secured to the other element by affixing the element to intermediate member(s) which in turn are affixed to the other element; and configurations in which one element is integral with another element, i.e., one element is essentially part of the other element.
The strips of material 30 can comprise any suitable material. Suitable materials include, but are not limited to: woven and nonwoven webs, and polymeric materials such as apertured films, foams, scrims, and netting. Suitable woven and nonwoven materials can be comprised at least partially of fibers derived from natural sources (e.g., pulp, cotton, wool, rayon, viscose fibers), synthetic fibers (e.g., polyester, polypropylene, nylon, aramid, polyethylene, polylactic acid, and biodegradable fibers) or from a combination of natural and synthetic fibers. Synthetic fibers, if present, may be in any suitable form, including, but not limited to in the form of bi-component fibers, splittable fibers, and/or microfibers.
In one non-limiting embodiment, the strips of material 30 comprise a nonwoven fabric (or “nonwoven material”). The nonwoven fabric can comprise any suitable type of nonwoven fabric. The nonwoven fabric comprising the strips of material 30 can be described by the process by which it is made. The strips of material 30 can be made by a number of different processes. These include, but are not limited to: air laid, wet laid, meltblown, spunbonded, carded, thermally bonded, air-through bonded, powder bonded, latex bonded, solvent bonded, spunlaced, and combinations of the foregoing. In certain embodiments, the nonwoven fabric can comprise a spunbond polypropylene having a basis weight of between about 15-80 g/m2, which is made of at least some fibers having a denier of between about 1-4. In one embodiment, a 45 grams/m2 polypropylene fiber spunbonded/meltblown/spunbonded hydroentangled (or “SMS”) nonwoven batting with 1.4 denier spun fibers known as AVSPUN™ obtained from Avgol Ltd. of Holon, Israel, can be used. Such a material is described in greater detail in Avgol's U.S. Patent Publication US 2004/0010894 A1.
If desired, the materials forming the strips 30 may be further processed prior to forming the cleaning article 20. The materials forming the strips 30 may be further processed by printing, mechanical deformation, area densification or other methods known in the art to impart additional properties such as but not limited to color, abrasion and texture. Examples of post processing technologies that may be used are described in the following patent publications: US 2004/0131820 A1 (PCT WO 04/058117 A1), and PCT WO 04/049,061.
The strips of material 30 can be of any suitable dimensions. By way of example, the strips 30 can range in length from greater than or equal to about ¼ inch to about 2 inches (about (5 cm), or more, and in width from greater than ⅛ inch (about 3 mm), or alternatively, greater than or equal to about 4.5 mm, or alternatively, greater than or equal to about 3/16 inches (about 4.8 mm) to about 1 inch (about 2.5 cm), or more. In certain embodiments, the strips of material 30 may have a width that is greater than about twice the thickness of the strips of material, or any multiple of their thickness greater than two. In certain embodiments, the strips of material 30 have a length of about 0.5-1.5 inch (about 1.3-3.8 cm), a width of about 0.1-0.4 inch (about 0.3-1 cm), and a thickness of about 0.01-0.02 inch (about 0.3-0.5 mm).
The strips 30 may also be provided with other features. In some embodiments, the strips 30 may be provided with slit or frayed ends (for example, a wide strip could be provided with a free distal end 30B that has one or more (e.g., multiple) slits therein to form fingers, branches, or the like). In these, or other embodiments, slits can also be provided along the side edges of the strips 30 (that is, along the lengths of the strips 30). In addition, in other embodiments, any of the portions of the strips 30 that are described herein as having slits formed therein, could alternatively be cut in other manners, such as with a curvilinear cut, or a serrated cut to form zig-zag or saw-toothed edge on the same.

In some embodiments, it may be desirable for the outer layer 38 and inner layer 40 to be comprised of certain materials that are resistant to conditions encountered during cleaning processes. That is, it may be desirable to use materials that do not attract soils during use, such as cellulose-based materials, which have an anionically charged surface. For example, sponges and other types of cleaning implements that are comprised of cellulosic materials may be subject to increased soiling when used with soaps that contain certain cationic polymers in certain concentration levels. In such cases, therefore, it may be desirable for the cleaning article 20 to be comprised of at least some materials that have cationically charged surfaces, such as polyester. Such a cleaning article 20 can, for example, be comprised either entirely of polyester, or from a blend of polyester and some other material, such as polypropylene.
In one non-limiting embodiment, the outer layer 38 comprises a nonwoven fabric or material. The nonwoven fabric can comprise any suitable type of nonwoven fabric. The nonwoven fabric outer layer 38 can, for example, comprise any of the types of nonwoven fabrics described herein as being suitable for use as the strips 30, though the same types of nonwoven fabrics need not be used for both the outer layer 38 and the strips 30. Such materials include the Avgol Ltd. material, and the post processed materials described above.
In certain embodiments, at least a portion of the inner layer 40 is liquid resistant or liquid impervious. This will allow the user's hand to stay dry and free from being soiled when using the cleaning article, such as when cleaning a car. In the embodiment shown, the entire inner layer 40 is liquid impervious. The inner layer 40 can comprise any suitable liquid resistant or liquid impervious material. The inner layer 40 may comprise a woven or nonwoven material, polymeric films such as thermoplastic films of polyethylene or polypropylene, or composite materials such as a film-coated nonwoven material. In one non-limiting embodiment, the inner layer comprises a film such as described in U.S. Pat. No. 5,518,801 entitled “Web Materials Exhibiting Elastic-Like Behavior” which issued to Chappell, et al. on May 21, 1996.
In the embodiment shown in
The components of the first and second portions, 34 and 36, of the body portion 22 and the strips of material 30 can be joined together in any suitable manner. Suitable manners include, but are not limited to, by adhesives, thermal bonding, thermal-mechanical bonding, mechanical, and ultrasonic bonding. The layers of the first and second body portions, 34 and 36, can be joined together over any suitable portion or portions of their faces in any suitable manner. It may be desirable for these portions to be joined in a manner that preserves their flexibility. The first and second portions, 34 and 36, of the body portion 22 can also be joined to each other at, or adjacent to their peripheries to provide an opening for the user's hand.
The strips 30 can be joined to the body portion 22 in any suitable manner. Suitable manners include, but are not limited to, by adhesives, thermal bonding, thermal-mechanical bonding, mechanical, and ultrasonic bonding. As shown in

Numerous other embodiments are possible.
The cleaning article 20 shown in
The topsheet 46 of the cleaning article shown in
It may be desirable, in the case of an article for washing vehicles, for the apertured topsheet 46 to be made from materials that are sufficiently soft so as not to scratch the surface of the vehicle being washed. Apertured films and apertured nonwoven materials may provide these properties. Nonwoven materials comprise a fabric assembly having structural integrity that are formed by continuous or discontinuous structural elements comprising strands or fibers that are held together in random or ordered (e.g., parallel, etc.) array. The strands or fibers can be held together by (a) mechanical interlocking (e.g., as a consequence of needling or hydroentangling, etc.) in the case of thermoplastic fibers, heat-induced bonding (i.e., fusing), or (b) an impregnation or coating of a bonding agent.
Suitable apertured formed films are described in U.S. Pat. No. 3,929,135, entitled “Absorptive Structures Having Tapered Capillaries”, which issued to Thompson on Dec. 30, 1975; U.S. Pat. No. 4,324,246 entitled “Disposable Absorbent Article Having A Stain Resistant Topsheet”, which issued to Mullane, et al. on Apr. 13, 1982; U.S. Pat. No. 4,342,314 entitled “Resilient Plastic Web Exhibiting Fiber-Like Properties”, which issued to Radel, et al. on Aug. 3, 1982; U.S. Pat. No. 4,463,045 entitled “Macroscopically Expanded Three-Dimensional Plastic Web Exhibiting Non-Glossy Visible Surface and Cloth-Like Tactile Impression”, which issued to Ahr, et al. on Jul. 31, 1984; U.S. Pat. No. 4,637,819 entitled “Macroscopically Expanded Three-Dimensional Polymeric Web for Transmitting Both Dynamically Deposited and Statically Contacted Fluids From One Surface to the Other”, which issued to Ouellette, et al. on Jan. 20, 1987; U.S. Pat. Nos. 4,609,518 and 4,629,643 both issued to Curro, et al. on Sep. 2, 1986 and Dec. 16, 1986, respectively; U.S. Pat. No. 5,006,394 entitled “Multilayer Polymeric Film” issued to Baird on Apr. 9, 1991; and U.S. patent application Ser. No. 08/442,935 entitled “Fluid Transport Webs Exhibiting Surface Energy Gradients” filed in the name of Ouellette, et al. on May 31, 1995 (PCT Publication WO 96/00548, published Jan. 11, 1996). One suitable apertured formed film topsheet for the topsheet 46 is the formed film described in one or more of the above patents and marketed on sanitary napkins by The Procter & Gamble Company of Cincinnati, Ohio as the “DRI-WEAVE” topsheet. In addition, apertured spunlace materials can be obtained from BBA Nonwovens.
If the apertured topsheet 46 comprises a nonwoven material, the apertured topsheet 46 can comprise any suitable nonwoven material. In the embodiment shown in
Apertured nonwoven materials may also be distinguished from scrim materials in several other respects. While scrims also have apertures, scrims are often formed from continuous length intersecting structural elements that have circular cross-sections. The structural elements of scrims will often form raised nodes where they intersect and are welded together, while nonwoven materials often have structural elements that intersect, but at less pronounced, generally planar points of intersection. It is believed that, in some cases, the nodes of some scrim materials can scratch some surfaces, such as the surfaces of a vehicle. Also, scrims may tend to have too high of an open area, thereby allowing soil to easily come into contact with the surface of the vehicle.
The apertured topsheet 46 can have any suitable amount of open area. The apertured topsheet 46 may have between about 20 and about 80% open area, alternatively between about 30 and about 70% open area, or alternatively, between about 40 and about 60% open area. The apertures may permit water (and/or a cleaning composition) and/or soil particles to pass through their openings and into the underlying secondary component material directly beneath, thereby preventing direct interaction between these soil particles and the surface of the vehicle.
Suitable underlying materials that can be used in combination with an apertured topsheet 46 include, but are not limited to, high loft nonwoven polymeric battings having a basis weight of 40 grams/m2 (gsm) and above. Such materials are available from Polymer Group Incorporated (“PGI”) of Mooresville, N.C., U.S.A. In one embodiment, a 75 grams/m2 polypropylene, polyester, PE/PP bicomponent fiber nonwoven batting from PGI that is made by carding and then through air bonded can be used.
The secondary component 48, which is best seen in
In embodiments in which it is desirable for the secondary component 48 to be capable of absorbing and/or retaining liquids, the secondary component 48 may be manufactured from a wide variety of materials, including those commonly used in absorbent articles. Suitable absorbent materials comminuted wood pulp which is generally referred to as airfelt. Examples of other suitable absorbent materials include cotton fibers or cotton lintels, creped cellulose wadding; meltblown polymers including coform; chemically stiffened, modified or cross-linked cellulosic fibers; synthetic fibers such as crimped polyester fibers; peat moss; tissue including tissue wraps and tissue laminates; absorbent foams; absorbent sponges; superabsorbent polymers (in fibrous and particulate form); absorbent gelling materials; or any equivalent material or combinations of materials, or mixtures of these. Absorbent materials may comprise folded tissues, cotton batts, woven materials, nonwoven webs, rayon including needle punched rayon, and thin layers of foam. The secondary component 48 may comprise a single material or a combination of materials.
The first impervious liner 50, second impervious liner 52, and backing layer 54 can comprise any suitable materials. Suitable materials include, but are not limited to, those materials specified for use as the inner layer and outer layer, respectively, of the embodiment shown in
In other alternative embodiments, the cleaning article need not be in the form of a glove or mitt that is worn on a portion of a user's hand. In such other embodiments, for instance, the cleaning article can be used in conjunction with a handle, or holder. Such a cleaning article could be configured to fit into an opening such as that into which the user's hand is inserted in the embodiments described above. In addition, in the embodiment shown in
In other embodiments, the cleaning article 20 need not comprise a portion that completely covers the back of the user's hand, as in the case of a glove or mitt. In other embodiments, for example, the cleaning article can be in the form of a wipe that does not have any portions covering the back of the user's hand. In other embodiments, the cleaning article can have a portion that only covers (or is merely worn adjacent to) part of the back of the user's hand. One example of such an embodiment is one in which the cleaning article is similar in form to a wipe, but which has a portion at one end thereof into which the wearer can slip the top portions of their fingers, which only covers (or is merely worn adjacent to) part of the back of the user's hand. Such embodiments may cover, for example only: the backs of the user's fingers; the backs of the top portion of the user's fingers; or the a portion of the back of the user's hand, but not all of the back of the user's hand.
Additional embodiments of the cleaning article 20 are shown in
As in the previously described embodiments, the body portion 22 has a first side and a second side, with each of these sides having a total surface. In the presently described embodiments of the cleaning article, at least one of the first and second sides comprises a first region defining a first surface and a second region defining a second surface, with the first region comprising a substantially planar material. Within the description of the embodiments of
In order to facilitate the recognition of the visual distinction, for example to obtain enhanced cleaning functionality, at the first region of substantially planar material, the surface of the first region of substantially planar material comprises less than about 90% of the total surface of the at least one side on which it is provided. In additional embodiments, the surface of the first region comprises less than about 50% of the total surface of the at least one side on which it is provided, or alternatively, less than about 33% of the total surface of the at least one side on which it is provided, or alternatively, less than about 25% of the total surface of the at least one side on which it is provided. The first region of substantially planar material can be located at any desired location on one or both sides of the body portion. In one embodiment, the first region is located in the finger area 70 of the body portion. The first region of substantially planar material can cover substantially the entire finger area as shown by the first region 72 of substantially planar material included in the cleaning article of
The first region of substantially planar material may be provided on either the first side 26 of the body portion or on the second side 28 of the body portion, or on both sides, as desired. For example, in the embodiment of
As described, the first region of substantially planar material is visually distinct from the second region of the side on which it is provided. Thus, with reference to
The substantially planar material of the first region may be any material which provides a desired cleaning functionality. In one embodiment, the enhanced cleaning functionality is an ability to remove soil by application of increased pressure in the first region. Examples of suitable materials include any of the woven and non-woven materials previously described herein, including, but not limited to, various natural and/or synthetic woven and non-woven materials. As indicated, the substantially planar material is typically in a sheet form and may be formed, for example, from polyolefin, polyester, rayon, viscose, cotton, or the like, including mixtures thereof, or from other materials known in the art. In one specific embodiment, the first region is formed from a 60 gsm nonwoven material comprising 70% rayon and 30% polyethylene terephthalate (PET), impregnated with acrylic resin and having a blue and white pattern. In another specific embodiment, the first region is formed from an 80 gsm nonwoven material comprising 90% viscose and 10% PET, impregnated with acrylic resin and having a blue and white pattern.
In a specific embodiment, the substantially planar material is sufficiently abrasive to remove soil from a surface to be cleaned without causing visually perceptible scratching of the surface, i.e., scratches which are visible to the naked eye. In a more specific embodiment, the planar material is sufficiently abrasive to remove soil from a car clearcoat surface without causing visually perceptible scratching of the surface. In a preferred embodiment, the planar material is sufficiently abrasive to remove tough soils, i.e., those typically difficult to remove with gentle wiping, such as tar, bugs, bird droppings, and the like, without causing visually perceptible scratching of the surface. Various techniques may be employed to assess if a substantially planar material meets these abrasiveness limitations. One suitable method is described as follows, but other methods may be employed as well.
In one test method, 4×12 inch ACT Laboratories' test panels, coated black paint and clearcoat, are soiled with a consumer relevant bug soil (for instance, a type of cricket soil could be used), baked and cleaned with the abrasive material. Alternatively, real bug soils obtained from ACT panels attached to consumer vehicles can be used. Bug soil is splattered onto test panels such that it represents visually what bug soil looks like on consumers' vehicles. Soiled panels are placed on a baking sheet and baked in a convection oven to simulate realistic heating that can occur on vehicle surfaces. The panels are then cooled. In the cleaning procedure, the test panel is placed on a stand at a 5° angle in a sink and spray rinsed with a 50 psi dynamic nozzle from a 3 foot distance, starting at the top of the panel and moving down. The substantially planar material is dipped in a soap solution and used to scrub the bug debris until the debris is removed. A nonlimiting example of a soap solution is a dilution of Mr. Clean™ AutoDry™ Carwash refill soap in ordinary tap water at a ratio of 1 part soap to 100 parts of ordinary tap water. The panel is then rinsed as described, followed by rinsing with distilled water and air drying. Once dry, the panel is visually inspected with the naked human eye to determine if the debris has been removed and if any scratching is detectable to the naked eye. Removal of the debris with no visually perceptible scratching warrants a passing grade, while failure to remove the debris or removal with visually perceptible scratching warrants a failing grade. In one embodiment, the substantially planar material employed in the first region exhibits a passing grade when evaluated according to this method.
In one embodiment, the planar material comprises an apertured material, for example a woven or nonwoven material provided with apertures. In a more specific embodiment, the apertured material is provided with apertures having an average opening dimension of at least about 0.5 mm, at least about 0.75 mm, at least about 1 mm, or at least about 1.25 mm. The apertured material may be provided with apertures having openings of any of a variety of shapes, including oval, circular, polygonal, including diamond, square, etc., half-moon, or slit shape, or mixtures thereof. In one specific embodiment, the apertured material is provided with apertures of diamond shape.
As in the previously described embodiments, the body portion 22 has a first side and a second side, with the second side 28 being shown in each of
In the embodiment of
While embodiments of
The finger welds which may be used to form the finger positioning portions may be formed by heat sealing, ultrasonic welding, adhesive sealing, stitching, and/or any other technique known in the art for adhering materials of the type used in forming the first side and the second side of the body portion. In the event that a side of the body portion is formed from two or more layers, it is only necessary that the innermost layer of the first side and the innermost layer of the second side are adhered to one another. In a further embodiment however, the welds extend through all layers of each side of the body portion.
The cleaning articles described herein can be manufactured in any suitable manner. The cleaning articles can be made by machine, by hand, or partially by machine and partially by hand. The cleaning article shown in the various figures can be made in a number of different manners. In one non-limiting embodiment, the cleaning article shown in
The strips of material 30 may be attached to the body portion 22 at any suitable step in the process of making the cleaning article. It may be desirable to supply one or more layers of material that will be cut to form the strips of material 30. The layer(s) of material may either be cut before, or after, they are joined to the material that will underlie the strips of material 30 in the finished cleaning article. In some embodiments, it is desirable to at least partially cut the layer(s) or material into strips before they are joined to the material that will underlie the strips of material 30 in the finished cleaning article, for ease of manufacture.
It may be desirable to leave some portions of the layer(s) of material uncut in order more easily join the same to the material that will underlie the strips of material 30 in the finished cleaning article. For example, rather than having to control and attach a plurality of strips of material to the material that will underlie the strips of material 30 in the finished cleaning article, it may be desirable to leave a portion of the layer(s) of material uncut forming an uncut region in the same. This uncut region can then be used to control and join more than one strip of material to the material that will underlie the strips of material 30 in the finished cleaning article. For instance, in the embodiment shown in
In some cases, it is desirable to attach the strips to the first portion of the body portion 22 before the first and second portions of the body portion are joined together. In other cases, the strips of material 30 may be attached to the first portion of the body portion 22 after the first and second portions of the body portion are joined together.
The cleaning article 20 can be made in any suitable manner on a manufacturing line. In some embodiments of the method of making the cleaning article, the components that will be assembled into the cleaning articles may be oriented on the manufacturing line in a manner with the portions of the components that will form the transverse centerline of the cleaning article are oriented in the direction of the movement of the product on the manufacturing line (that is, in the “machine direction” or “MD”). In other words, the transverse centerline T of the products being manufactured will point in the machine direction, and the longitudinal centerline, L, of the products will point in a direction perpendicular thereto. In other embodiments of the method of making the cleaning article, the components being assembled may be oriented in a direction so that the transverse centerline is perpendicular to the machine direction (that is, oriented in the “cross-machine direction” or “CD”) and the longitudinal centerline, L, is oriented in the machine direction. It may be desirable, for ease of manufacture, for the components of the cleaning article 20 to be assembled with strips of material 30 oriented with their lengths running in the machine direction. Thus, if the cleaning article 20 has strips of material 30 oriented in the transverse direction, it may be desirable for the components of the cleaning article 20 to be assembled in an orientation where components are oriented so that the transverse centerline of the finished article will be traveling in the machine direction. However, it is also possible for the components of the cleaning article 20 to be assembled with strips of material 30 oriented with their lengths running in the cross-machine direction.
