Description




FIELD OF THE INVENTION




The present invention relates to protective garments. More specifically, this invention relates to padded protective garments.




BACKGROUND




Disposable protective garments worn by workers prevent liquids or dust from reaching the skin, thereby preventing skin irritation or damage. Besides being liquid or particulate barriers, these garments may also be breathable permitting greater comfort. The desirability of disposing of the garments after use is due to the relatively high cost of washing them.




Often workers wear disposable protective garments when cleaning in wet environments, such as the interiors of brewery vessels. Unfortunately, a fall may result during cleaning. Consequently, workers often wear separate, individual pads over the garments providing a cushion if a fall should occur. In addition, it may be desirable for workers to wear separate, individual pads over disposable garments during other jobs as well, such as finishing floors or painting.




Unfortunately, the wearing of separate individual pads suffers several disadvantages. Putting the pads on takes time, thereby lengthening the completion of the job. In addition, some workers may not wear some or all of the pads, thereby increasing their risk of injury. Furthermore, often these pads are constructed from a material that absorbs liquids. When the pads absorb liquid, this liquid becomes concentrated on the garment, thereby increasing the risk of the liquid penetrating the garment and reaching the worker's skin.




Accordingly, a disposable protective garment that improves worker efficiency and protection will improve over conventional protective garments.




DEFINITIONS




As used herein, the term “nonwoven web” refers to a web that has a structure of individual fibers or filaments that are interlaid, but not in an identifiable repeating manner. Nonwoven webs have been, in the past, formed by a variety of processes known to those skilled in the art such as, for example, meltblowing, spunbonding and bonded carded web processes.




As used herein, the term “spunbonded web” refers to a web of small diameter fibers and/or filaments that are formed by extruding a molten thermoplastic material as filaments from a plurality of fine, usually circular, capillaries in a spinneret with the diameter of the extruded filaments then being rapidly reduced, for example, by non-eductive or eductive fluid-drawing or other well known spunbonding mechanisms. The production of spunbonded nonwoven webs is illustrated in patents such as Appel, et al., U.S. Pat. No. 4,340,563; Dorschner et al., U.S. Pat. No. 3,692,618; Kinney, U.S. Pat. Nos. 3,338,992 and 3,341,394; Levy, U.S. Pat. No. 3,276,944; Peterson, U.S. Pat. No. 3,502,538; Hartman, U.S. Pat. No. 3,502,763; Dobo et al., U.S. Pat. No. 3,542,615; and Harmon, Canadian Pat. No. 803,714.




As used herein, the term “meltblown fibers” means fibers formed by extruding a molten thermoplastic material through a plurality of fine, usually circular, die capillaries as molten threads or filaments into a high-velocity gas (e.g. air) stream that attenuates the filaments of molten thermoplastic material to reduce their diameters, which may be to microfiber diameter. Thereafter, the meltblown fibers are carried by the high-velocity gas stream and deposited on a collecting surface to form a web of randomly disbursed meltblown fibers. The meltblown process is well-known and is described in various patents and publications, including NRL Report 4364, “Manufacture of Super-Fine Organic Fibers” by V. A. Wendt, E. L. Boone, and C. D. Fluharty; NRL Report 5265, “An Improved device for the Formation of Super-Fine Thermoplastic Fibers” by K. D. Lawrence, R. T. Lukas, and J. A. Young; and U.S. Pat. No. 3,849,241, issued Nov. 19, 1974, to Buntin, et al.




As used herein, the term “microfibers” means small diameter fibers having an average diameter not greater than about 100 microns, for example, having a diameter of from about 0.5 microns to about 50 microns, more specifically microfibers may also have an average diameter of from about 1 micron to about 20 microns. Microfibers having an average diameter of about 3 microns or less are commonly referred to as ultra-fine microfibers. A description of an exemplary process of making ultra-fine microfibers may be found in, for example, U.S. Pat. No. 5,213,881, entitled “A Nonwoven Web With Improved Barrier Properties”, incorporated herein by reference in its entirety.




As used herein, the term “sheet” refers to a material that may be a film, nonwoven web, woven fabric, knit fabric, or laminates of the like.




As used herein, the term “disposable” is not limited to single use articles, but also refers to articles that can be discarded after only a few uses. Generally, a disposable article is not intended to be cleaned by automated devices, such as a washing machine.




As used herein, the term “garment” is any article of clothing, such as a glove, sleeve protector, apron, shirt, pants, shoe, coat or coverall.




As used herein, the term “pad” refers to a cushionlike mass of soft material used as filling or for protection against falling, jarring, scraping, or other injury. A pad may be constructed from any suitable material, such as foams, textiles, fibers, plastics, bubble-pack, bulky cloth, wadding, or elastic materials, such as those disclosed in U.S. Pat. No. 4,720,415, to Vander Wielen et al., and U.S. Pat. No. 5,624,729, to Cohen et al., which disclosures are hereby incorporated by reference.




As used herein, the term “pocket” refers to at least one piece of material that secures an article, such as a pad, to a garment.




As used herein, the term “closure mechanism” is a device used to close and open a garment permitting a person to wear and remove the garment. Examples of closure mechanisms include zippers, button fasteners, clip fasteners, snap fasteners, magnetic fasteners, and hook and loop connectors.




As used herein, the term “machine direction” refers to the planar dimension of a nonwoven fibrous web, which is in the direction of travel during web formation.




As used herein, the term “cross-machine direction” refers to the planar dimension of a nonwoven fibrous web, which is the direction perpendicular to the machine direction.




As used herein, the term “liquid resistant” refers to material having a hydrostatic head of at least about 25 centimeters as determined in accordance with the standard hydrostatic pressure test AATCC TM No. 127-1980.




As used herein, the term “breathable” refers to material having a Frazier porosity of at least about 25 cubic feet per minute per square foot (cfm/ft


2


) as determined in accordance with the standard Frazier porosity test Federal Test Method 5450, Standard no. 191A or a Moisture Vapor Transmission Rate (MVTR) of at least about 500 grams per square meter per 24 hours (g/m


2


/24 h) as determined in accordance with the standard MVTR test method ASTM E96-80.




As used herein, the term “particle resistant” refers to a fabric having a useful level of resistance to penetration by particulates. Resistance to penetration by particulates may be measured by determining the air filter retention of dry particles and can be expressed as a particles holdout efficiency. More specifically, particle hold-out efficiency refers to the efficiency of a material at preventing the passage of particles of a certain size range through the material. Particle holdout efficiency may be measured by determining the air filter retention of dry particles utilizing tests such as, for example, IBR Test Method No. E-217, Revision G (Jan. 15, 1991) performed by InterBasic Resources, Inc. of Grass Lake, Michigan. Generally, a high particle holdout efficiency is desirable for barrier materials/fabrics. Desirably, a particle resistant material should have a particle hold-out efficiency of at least about 40 percent for particles having a diameter greater than about 0.1 micron.




As used herein, the term “polymer” generally includes homopolymers, copolymers, such as block, graft, random and alternating copolymers, terpolymers, and blends and modifications thereof. Furthermore, unless otherwise specifically limited, the term “polymer” shall include all possible geometrical configurations of the material. These configurations include isotactic, syndiotactic and random symmetries.




As used herein, the term “consisting essentially of” does not exclude the presence of additional materials that do not significantly affect the desired characteristics of a given composition or product. Exemplary materials of this sort would include pigments, antioxidants, stabilizers, surfactants, waxes, flow promoters, optical brightners, antistats, particulates or materials added to enhance processability of a composition.




As used herein, the term “couple” includes, but not limited to, joining, connecting, fastening, linking, or associating two things integrally, interstitially, directly, or indirectly together. Coupling includes using means such as stitching, ultrasonic bonding, solvent welding, adhesives, adhesive tapes, mechanical fasteners, snaps, hook and loop connectors, clips, thermal bonding, or securing an article to a member using an intermediate mechanism, such as a pocket coupled to the member.

DETAILED DESCRIPTION




Referring now to the drawings, wherein the reference numerals designate corresponding structure throughout the views, and referring in particular to

FIGS. 1-2

, there is shown (not necessarily to scale) an exemplary improved disposable padded protective garment


100


.




Referring to

FIG. 1

, the garment


100


includes a body section


104


, first and second arm sections


108


and


112


, and first and second leg sections


116


and


120


. The exemplary garment


100


takes the form of a coverall, such as the coveralls disclosed in U.S. Pat. No. 5,487,189, entitled, “Coveralls Having Reduced Seams and Seamless Shoulder Construction And Method Of Manufacture”, issued Jan. 30, 1996, to Bell and whose disclosure is hereby incorporated by reference. However, the garment


100


could also take the form of other articles of clothing, such as a coat, gowns, pants, or garments. Other exemplary garments are disclosed in U.S. Pat. No. 4,670,193, to Morell et al. and U.S. Pat. No. 5,509,142, which disclosures are hereby incorporated by reference.




The garment


100


further includes a first arm cuff


130


, a second arm cuff


132


, a collar


134


, and a closure mechanism


136


. The garment


100


could also include hood, boots, elastic waist, and/or elastic ankle cuffs. The garment also has e exterior


124


and an interior


128


.




The garment


100


is constructed from a sheet material


140


that includes a first side


150


on the exterior


124


and a second side


160


on the interior


128


of the garment


100


.




The sheet material


140


may be constructed from at least one bonded carded web, spunbonded filament web, or meltblown fiber web. Also, the sheet material


140


may include at least one knit material, woven material, or film.




The sheet material


140


may be formed from polymers, ethylene and at least one vinyl monomer copolymer, ethylene and n-butyl acrylate copolymer, cellulosic material, or acrylic resins. These compounds may be blended together. Examples of polymers may include polyamides, polyolefins, polyesters, polyvinyl alcohols, polyurethanes, polyvinyl chlorides, polyfluorocarbons, polystyrenes, and caprolactams. Examples of an ethylene and vinyl monomer copolymer may include poly(ethylene vinyl acetates). If the sheet material


140


is formed from a polyolefin, the polyolefin may be polyethylene, polypropylene, polybutene, ethylene copolymers, propylene copolymers and butene copolymers.




The sheet material


140


may have a basis weight ranging from about 15 grams per square meter (hereinafter may be abbreviated as “gsm”) to about 300 gsm. Furthermore, the sheet material


140


may have a basis weight ranging from about 20 gsm to about 100 gsm. Desirably, the sheet material


140


may have a basis weight ranging from about 40 gsm to about 75 gsm. More desirably, the sheet material


140


may have a basis weight of about 44 gsm, about 61 gsm, or about 75 gsm.




The sheet material


140


may have a thickness less than about 12 millimeter (hereinafter may be abbreviated as “mil”). Furthermore, the sheet material


140


may have a thickness less than about 5 millimeter. Desirably, the sheet material


140


may have a thickness less than about 0.40 millimeter. More desirably, the sheet material may have a thickness of about 0.36 millimeter or about 0.33 millimeter.




An exemplary substance for the sheet material


140


is a spunbonded polypropylene continuous filament web. This web can be formed utilizing a conventional spunbonding process and is available from the Kimberly-Clark Corporation, Neenah, Wisconsin.




Another exemplary substance for the sheet material


140


is a high pulp content spunbonded continuous filament composite. Such a composite may have a wide range of basis weights and can be composed of about 84 percent, by weight, pulp and about 16 percent, by weight, spunbonded polypropylene continuous filament web. This composite can be formed essentially as described in U.S. Pat. No. 5,284,703, by C. H. Everhart, et al., entitled “High Pulp Content Nonwoven Composite Fabric”, which disclosure is hereby incorporated by reference.




Yet another exemplary substance for the sheet material


140


may be a through-air bonded carded web, such as, for example a through-air bonded carded web composed of about 60 percent, by weight, polyester staple fibers and about 40 percent, by weight, bi-component polyethylene/polyester staple fibers. The web may be formed utilizing conventional carding equipment and thermally bonding the fibers utilizing a conventional heated through-air treatment or point bonding.




Generally, the sheet material


140


may be treated with compositions improving resistance to liquid and reducing static buildup, such as Zepel® and Zelec® available from E. I. du Pont De Nemours, or treated with compositions, such as hydrophilic surfactants.




Alternatively, the sheet material


140


may include multiple layers manufactured from the previously described polymers, copolymers, cellulosic materials, and resins forming a seamless laminate having desirable barrier properties.




For example, a useful multi-layer sheet material


140


may include at least one web of meltblown fibers, which may include meltblown microfibers, with at least one spunbonded continuous filament web. Another exemplary multi-layer sheet material


140


may include layers of spunbonded continuous filaments webs, meltblown fiber webs, a bonded carded web or other nonwoven fabric, resulting in an inexpensive sheet material


140


fairly well suited for disposable products.




Still another useful multi-layer sheet material


140


may consist of a three-layer fabric, incorporated into a garment, which is available from the Kimberly-Clark Corporation under the trade designation KLEENGUARD®. The three-layer fabric includes a first outer ply of a spunbonded web, a middle ply of a meltblown web, and a second outer ply of a spunbonded web (hereinafter may be abbreviated as “SMS”). These plies may be joined together by conventional thermal bonding techniques. If the SMS includes a polyolefin, it may be a random block copolymer of propylene and ethylene, which contains about 3 percent or more, by weight, ethylene. The fibers and/or filaments may be formed from blends that contain various pigments, additives, strengthening agents, and flow modifiers. Such fabrics are described in U.S. Pat. Nos. 4,041,203, 4,374,888, and 4,753,843, which disclosures are hereby incorporated by reference. Those patents are assigned to the Kimberly-Clark Corporation, the assignee of the present invention.




The multi-layer sheet material


140


may have a total basis weight of between about 15 gsm to about 300 gsm. For example, the multi-layer sheet material


140


may have a basis weight ranging from about 40 gsm to about 175 gsm. Desirably, the multi-layer sheet material


140


may have a basis weight ranging from about 50 gsm to about 150 gsm.




For example, the multi-layer sheet material


140


may be a multi-layer nonwoven web of SMS construction, where each layer has a basis weight from about 9 gsm to about 70 gsm. Desirably, each layer may have a basis weight of from about 12 gsm to about 34 gsm. More desirably, each layer may have a basis weight of from about 14 gsm to about 27 gsm.




Desirably, the multi-layer sheet material


140


includes at least one film layer. Generally, the film will have a thickness ranging from about 0.025 mil to about 5.0 mil. For example, the film will have a thickness ranging from about 0.5 mil to about 3.0 mil. Desirably, the film will have a thickness ranging from about 1.0 mil to about 2.5 mil.




The films may be applied by extrusion coating the substrates and then passing the superposed materials through the nip of smooth calendar rolls. The films may be formed so they would create a layer on the substrate having a desired thickness.




Still another exemplary multi-layer sheet material


140


used for the present invention is a laminated fabric constructed by bonding together at least one layer of a nonwoven web with at least one layer of a film.




Generally, this laminated fabric may have a basis weight ranging from about 15 gsm to about 300 gsm. For example, the laminated fabric may have a basis weight ranging from about 20 gsm to about 150 gsm. As another example, the laminated fabric may have a basis weight ranging from about 20 gsm to about 75 gsm. Although the basis weight of the laminate will vary depending on the materials used, lower basis weight materials are desirable for comfort and conformability, while higher basis weight materials are desirable for toughness and durability. The laminated fabric permits combinations of materials providing high strength at relatively low basis weights.




Referring to

FIG. 2

, the garment


100


includes a plurality of pockets


170


and a plurality of pads


290


. The plurality of pockets


170


and the plurality of pads


290


may be constructed from the previously described polymers, copolymers, cellulosic materials, and resins as the sheet material


140


. It should be understood that any number of pockets and pads may be utilized with the garment


100


. For example, it is possible that only one pad and/or pocket may be utilized with the garment


100


.




The plurality of pockets


170


provides a means for coupling the plurality of pads


290


and includes a first elbow pocket


180


, a second elbow pocket


190


, a tailbone pocket


200


, a first knee pocket


220


, and a second knee pocket


230


, and the plurality of pads


290


includes a first elbow pad


294


, a second elbow pad


298


, a first knee pad


302


, a second knee pad


306


, and a tailbone pad


310


. The plurality of pockets


170


and pads


290


are exemplified as being substantially rectangular, but may be of any shape or size. Furthermore, the plurality of pockets


170


and pads


290


are desirably positioned in the interior


128


of the garment


100


, although they may also be positioned on the exterior


124


of the garment


100


as well. In addition, the plurality of pockets


170


may be positioned at the same location on the interior


128


and exterior


124


of the garment


100


.




The first and second elbow pockets


180


and


190


are substantially identical, as well as the first and second knee pockets


220


and


230


. Consequently, only the first elbow pocket


180


and the first knee pocket


220


will be described in detail hereinafter.




The first elbow pocket


180


may include a first side


182


, a second side


184


, a third side


186


, and a fourth side


188


. Desirably, the first side


182


, second side


184


, and third side


186


are coupled, for example stitched, to the sheet material


140


. This permits inserting and removing of the first elbow pad


294


. Only stitching three sides


182


,


184


, and


186


to the sheet material


140


minimizes thread holes, which may allow moisture to enter the interior


128


of the garment


100


. Alternatively, the fourth side


188


may be coupled to the sheet material


140


substantially permanently securing the first elbow pad


294


to the sheet material


140


.




The tailbone pocket


200


may include a first side


202


, a second side


204


, a third side


206


, and a fourth side


208


. Desirably, the first side


202


, second side


204


, and third side


206


are coupled, for example stitched, to the sheet material


140


. This permits inserting and removing of the tailbone pad


310


. In addition, at least one adhesive strip


210


may be used to further secure the tailbone pad


310


within the pocket


200


. Although only one adhesive strip


210


secures the tailbone pad


310


, it is contemplated that other adhesive strips may be utilized to secure the other pads as well. Alternatively, the fourth side


208


may be coupled to the sheet material


140


substantially permanently securing the tailbone pad


310


to the sheet material


140


.




The first knee pocket


220


may include a first side


222


, a second side


224


, a third side


226


, and a fourth side


228


. Desirably, the first side


222


, second side


224


, and third side


226


are coupled, for example stitched, to the sheet material


140


. This permits inserting and removing of the first knee pad


302


. Alternatively, the fourth side


228


may be coupled to the sheet material


140


substantially permanently securing the first knee pad


302


to the sheet material


140


.




Referring to

FIG. 3

, an alternative pocket


240


may include a first portion


244


and a second portion


264


. The first portion


244


may include a first side


248


, a second side


252


, and a third side


256


. Means for coupling, such as stitches


260


, secure these sides


248


,


252


, and


256


to the sheet material


140


creating a first opening


258


. The second portion


264


may include a first side


268


, a second side


272


, and a third side


276


. Stitches


280


secure these sides


268


,


272


, and


276


to the sheet material


140


creating a second opening


278


. The second opening


278


is within the first portion


244


, thereby creating an overlap. After manipulating a pad, such as the first elbow pad


294


, back and forth through both openings


258


and


278


, the pad will remain relatively secure within the pocket


240


.




Alternatively, the means for coupling the plurality of pads


290


may include using any suitable means, such as stitching, ultrasonic bonding, solvent welding, adhesives, adhesive tapes, mechanical fasteners, snaps, hook and loop connectors, clips, or thermal bonding.




The plurality of pads


290


may be constructed from any suitable material, such as foams, textiles, fibers, or plastics. Referring to

FIGS. 4 and 5

, one suitable material includes a first member


320


and a second member


340


. Both members


320


and


340


have substantially the same composition and form substantially the same structure. Consequently, only the composition and structure of the first member


320


will be described in detail hereinafter.




The first member


320


may be formed from polyethylene co-extruded with a nylon core creating a first substantially planar surface


324


and a second surface


326


forming a plurality of bubbles


328


. One example of this material is sold under the trade designation AIRCAP® RECYCLED BARRIER BUBBLE™ Cushioning Material by Sealed Air Corporation, Packaging Products Division, 201 Mayhill St., Saddle Brook, N.J. 07663.




The plurality of bubbles


328


may be varied in size, although one desired member


320


has each bubble


330


having a diameter D of 1.27 centimeter and a height H of 1.27 centimeter. Furthermore, each bubble


330


encapsulates a substance, typically air. However, other fluids or materials, such as solid granules, may be used. In addition, the pressure within the plurality of bubbles


330


may also be varied.




In one desired embodiment, each pad of the plurality of pads


290


includes a first member


320


positioned with its plurality of bubbles


328


facing a plurality of bubbles


352


formed on a second surface


348


of the second member


340


. Desirably, the plurality of bubbles


328


are offset and interlocked with the plurality of bubbles


352


. As a result, the respective planar surfaces


324


and


344


of the first member


320


and second member


340


are directed outwards. The members


320


and


340


may be coupled using any suitable means, such as adhesives, to form a pad.
