Abstract
A protective garment configured to facilitate easy donning of the garment is described. The sleeves and legs are shorted and held in a donning configuration by releaseably affixing at least a portion of upper and lower segments of the interior surface of each limb. This allows the garment to be handled and donned by the wearer, without the wearer touching an exterior surface of the garment. A method of preparing a protective garment for donning and a method of donning such a garment is also disclosed.

DETAILED DESCRIPTION
(11) The present invention pertains to a limited-use protective garment having a design that allows the garment to be configured into a donning configuration to facilitate easy donning of the garment. Such garments are of particular interest to work areas and industries such as, for example, healthcare, home improvement do-it-yourself, chemical, industrial, sanitation, cleanrooms, and other similar applications.
(12) In part,
(13) The manufacture of such garments 10 may be in accordance with known automated, semi-automated, or hand assembly procedures. It is desired that the protective garment 10 contains the fewest practical number of panels, portions or sections in order to reduce the number of seams in the garment for better barrier properties and to simplify the manufacturing steps. However, it is contemplated that the protective garment 10 may contain sections, panels, or portions of barrier fabrics that may have different degrees of strength to customize the coverall for a particular application. For example, the sleeve portions 18, 20 or other portions (e.g., leg portions, shoulder portions or back portions of the coveralls) may include double layers of barrier fabrics with very high levels of strength and toughness. Examples of the type of garments 10 contemplated may be found in U.S. Pat. No. 5,487,189 to Bell, which is herein incorporated by reference, and in those garments available from Kimberly-Clark Corporation (Roswell, Ga.) sold under the KLEENGUARD brand.
(14) Desirably, the left sleeve 18 may be an integral part of the left body panel 14 (i.e., the left body panel 14 cut to form a left sleeve 18). It is contemplated that the left sleeve 18 may be a separate piece of material that may be joined to the upper left body panel 26 by a seam (not shown). In the same way, it is desirable that the right sleeve 20 may be an integral part of the right body panel 16 (i.e., the right body panel 16 cut to form a right sleeve 20). It is contemplated that the right sleeve 20 may be a separate piece of material that may be joined to the upper right body panel 28 by a seam (not shown). A closure means 48 joins the left body panel 14 to the right body panel 16 on the front 10 of the garment 10. As shown in
(15) In the garment 10 illustrated in
(16) Desirably, the legs 22, 24 are formed in a way similar to the formation of the sleeves 18, 20. Desirably, the left leg 22 may be an integral part of the left body panel 14 (i.e., the left body panel 14 cut to form a left leg 22). It is contemplated that the left leg 22 may be a separate piece of material that may be joined to the left body panel 14 by a seam (not shown). In the same way, it is desirable that the right leg 24 may be an integral part of the right body panel 16 (i.e., the right body panel 16 cut to form a right leg 24). It is contemplated that the right leg 24 may be a separate piece of material that may be joined to the right body panel 16 by a seam (not shown).
(17) Desirably, the left body panel 14 and the right body panel 16 are constructed such that the left and right upper sections 26, 28 and the left and right leg sections 22, 24 of the garment 10 corresponding to the left and right body panels 14, 16 are each made from single, or integral, pieces of material. Although less desirable, it is contemplated that seams (not shown) may be used to join the upper sections 26, 28 to the leg sections 22, 24, to join the sleeves 18, 20 to the upper sections 26, 28, or to join combinations thereof.
(18) The seams used to form the garment 10 may be any type of seam that are appropriate in forming such garments. Such seams must be appropriate for the materials used in forming the garment 10, the strength required, and the level of security and protection that is desired. Typical seams used for such garments 10 include serged, sewn, bound, taped, welded, and heat sealed seams. Bound seams 241 (as shown in

(21) For the garment 10 illustrated in
(22) Similarly, the sheaths 34 present within the legs 22, 24 extend above the knee 23 of the garment 10 and the anchor strip 32 is anchored at an anchor point 35 at the end of the sheath 34, within the sleeves 18, 20. The manufacturer configures the garment 10 in the foreshortened configuration of
(23) The anchor points 35 may be any bonding means, attachment means, or structure that holds the anchor strip 32 in place such that the limbs of the garment 10 may be foreshortened (gathered) to facilitate easy donning. For example, the anchor points 35 may be an adhesive that attaches the end of the strip 32 to the sheath 34. Alternatively, the strip 32 may be physically stitched to the sheath 34 at the anchor point 35. Instead of an adhesive or stitch, or possibly in addition to such, the strip 32 may be attached to the sheath 34 by an ultrasonic bond.
(24) The sheath 34 and anchor strip 32 are constructed to cooperate to allow the limbs of the garment 10 to be foreshortened, keep the garment 10 in such a donning configuration prior to donning, and allow the wearer to re-lengthen the sleeves 18, 20 and legs 22, 24 while the garment 10 is being donned. To that end, the sheath 34 and anchor strip 32 are constructed with cooperative dimensions (i.e., compatible relative cross-sectional areas) such that the sheath 34 can pass along the anchor strip 32, but not pass so easily that the garment 10 cannot be held in the donning configuration prior to donning. To ensure elimination of the possibility of linting, all of seams of the sheath 34, anchor strip 32, and the garment 10 may be bound, or raw edges of the materials used may be otherwise encased. Finally, the sheaths 34 may be tubular structures that are attached to the interior surface 101 of the garment 10 or they may instead be extensions of the edge of the garment material, at the garment seams, which is pulled over back upon itself to form the sheath 34.
(25) While the sheaths 34 and anchor strips 32 of
(26)
(27) Instead of being anchored at a point 35 at the end of the sheath 34 within the interior of the garment 10, as illustrated in
(28) Additionally, the embodiment of
(29) The garments 10 illustrated in
(30) One skilled in the art would be able to see how various design and component combinations of the sheaths 34, 134, anchor strips 32, 132, donning loops 36, 136, and anchor points 35, 135 could be configured to produce variations of the inventive foreshortening structures. Such foreshortening structures provide the garment 10 with the ability to form a foreshortened donning configuration that facilitates easy donning of the garment.
(31) Such a garment 10 may be packaged by any means and/or method that allows for the wearer to easily access the garment 10 for donning, while ensuring that the wearer does not touch an exterior surface 103 of the garment 10. One exemplary method of preparing the garment 10 for donning may include the first step of first foreshortening the sleeves 18, 20 and legs 22, 24 of the garment 10. As discussed above for the garment 10 illustrated in
(32) Next, with the front side 12 of the garment 10 laying against a table, the gathered sleeves 118, 120 may then be folded toward the back side 13 of the garment. Similarly, the gathered legs 122, 124 may then be folded up toward the back side 13 of the garment 10, on top of the folded gathered sleeves 118, 120. Finally, the partially folded garment 10 may be flipped over such that the closure means 48 is facing upwards. The closure means 48 may be opened and the left and right opening flaps 50, 52 may be pulled open and around to the back 13 of the partially folded garment 10 such that only the interior surface 101 of the garment 10 is exposed on the outside of the folded garment.
(33) This method of folding of the garment 10 is only one potential method of folding the garment 10. Other methods that foreshortened the sleeves 118, 120 and the legs 122, 124 and fold the garment 10 such that the interior surface 101 is made available to the wearer during subsequent unfolding and donning are also contemplated. One skilled in the art would see how a different order of folding steps, numbers of folds, desired final folded dimensions, and other such considerations, may contribute to different methods of folding up the garment 10.
(34) Additionally, it may additionally be desirable to tuck the donning loops 36 into the wrist openings 92, 94 of the gathered sleeves 118, 120 and the ankle openings 96, 98 of the gathered legs 122, 124 such that the donning loops 36 are available on the inside of the garment 10 when the wearer later dons such a garment 10. It may also be desirable to tuck the anchor strips 32, 132 inside the gathered sleeve 118, 120 and gathered legs 122, 124 such that the wearer may be able to grasp them for greater control of the garment 10 limbs while donning the garment 10. Finally, such garments 10 are typically laundered and dried to remove any excessive particulates that may be present from the garment manufacturing process. This step would likely need to occur before the folding steps.
(35) Once folded, the garment 10 may be packaged in any method as known to package such garments 10 to form a protective garment package to be delivered to the wearer. Typically, the folded garment 10 may be placed in a bag and the bag sealed to form a garment package. It may be desired that the garment package be sterilized by any sterilization as is known for such products. Additionally, it may be desirable that the air within the bag be removed during packaging, such that the garment is vacuum-packed, prior to such sterilization.
(36) The garment 10 is configured such that the wearer of the garment may easily don the garment 10 without touching an exterior surface 103 of the garment and without letting any portion of the garment touch the floor. The wearer first grasps the interior surface 101 of the folded garment in such a way as to allow gravity to unfold the garment 10 into the donning configuration, such as illustrated in
(37) Next, the wearer inserts one of their arms into the appropriate sleeve (18 or 20) of the garment 10, making sure that that their hand engages the corresponding donning loop 36. The donning loop 36 may be engaged with the hand, the thumb, and/or finger. This is then repeated for the wearer's other arm. As the wearer extends their arms into the sleeves 18, 20 and pulls the garment shoulders 62 over their own shoulders, the gathered sleeves 118, 120 will lengthen to the length of the wearer's arms and provide the wearer with the appropriate arm fit. The wearer then completes the donning of the garment 10 by closing the closing means 48.
(38) In some embodiments, where the anchor strip 32 is designed to extend out of the sleeve and leg openings 92, 94, 96, 98 once the garment 10 is donned, the anchor strip 32 may provide an additional advantage in doffing the garment. When the wearer wishes to doff such a garment 10, he or she may grasp the exposed anchor strip 32 with a free hand and pull their hand or foot through the associated garment opening. Such a feature may be helpful in situations in which the wearer does not wish to touch the exterior surface 103 of the garment 10 after it has been worn.
(39) Another solution that facilitates easy donning of such a sterile garment 10 by orienting the garment 10 in a donning configuration is illustrated in
(40) In this embodiment of the garment 10, each of the sleeves 18, 20 has a lower sleeve segment 201 and an upper sleeve segment 203. The lower sleeve segment 201 is a part of the sleeve 18, 20 distal to the body portions 14, 16 and proximate to the sleeve openings 92, 94. The upper sleeve segment 203 is a part of the sleeve 18, 20 proximate to the body portions 14, 16 and distal to the sleeve openings 92, 94. Together, the segment lengths 202, 204 of the lower sleeve segment 201 and the upper sleeve segment 203 account for the total length 206 of the sleeve. As a reference point, each sleeve 18, 20 has a sleeve midpoint 205 that is located at the point along each sleeve length 206, approximately equidistant from the sleeve opening 92, 94 and the underarm 207 of the garment 10. The underarm 207 being where each sleeve 18, 20 meets the body portions 14, 16 of the garment 10. The lower and upper sleeve segments 201, 203 may be equal in length, such that the lower sleeve segment 201 would be the portion of the sleeve 18, 20 that lies below the sleeve midpoint 205 and the upper sleeve segment 203 would resultantly be the portion of the sleeve 18, 20 that lies above the sleeve midpoint 205.
(41) Alternatively, the lower and upper sleeve segments 201, 203 may have different lengths. The lower sleeve segment length 202 may be greater than the upper sleeve segment length 204. Alternatively, the lower sleeve segment length 202 may be less than the upper sleeve segment length 204. The upper sleeve segment length 302 may be approximately 25 percent or greater of the total sleeve length 206. In some embodiments, the upper sleeve segment length 204 may be 33 percent or greater, 50 percent or greater, between 33 percent and 75 percent, or between 33 percent and 66 percent of the total sleeve length 206.
(42) Similarly, each of the leg 22, 24 has a lower leg segment 211 and an upper leg segment 213. The lower leg segment 211 is a part of the leg 22, 24 distal to the body portions 14, 16 and proximate to the leg openings 96, 98. The upper leg segment 213 is a part of the leg 22, 24 proximate to the body portions 14, 16 and distal to the leg openings 96, 98. Together, the lengths 212, 214 of the lower leg segment 211 and the upper leg segment 213 account for the total length 216 of the leg. As a reference point, each leg 22, 24 has a leg midpoint 215 that is located at the point along the leg length 216, approximately equidistant from the leg opening 92, 94 and the crotch 217 of the garment 10. The crotch 217 being where each leg 22, 24 meets the body portions 14, 16 of the garment 10. The lower and upper leg segments 211, 213 may be equal in length, such that the lower leg segment 211 would be the portion of the leg 22, 24 that lies below the leg midpoint 215 and the upper leg segment 213 would resultantly be the portion of the leg 22, 24 that lies above the leg midpoint 215.
(43) Alternatively, the lower and upper leg segments 211, 213 may have different lengths. The lower leg segment length 212 may be greater than the upper leg segment length 214. Alternatively, the lower leg segment length 212 may be less than the upper leg segment length 214. The upper leg segment length 214 may be approximately 25 percent or greater of the total leg length 216. In some embodiments, the upper leg segment length 214 may be 33 percent or greater, 50 percent or greater, between 33 percent and 75 percent, or between 33 percent and 66 percent of the total leg length 216.
(44) As discussed above, the donning configuration (as shown in
(45) In the donning configuration, a lower portion of the interior surface 101 of each limb is releaseably affixed to an upper portion of the interior surface 101 of that same limb. As used herein, the term releaseably affixed refers to the limbs being held with enough tenacity to maintain the donning configuration during packaging, transport, removal from the packaging, shaking out of the garment 10 by the wearer, and initiation of the donning process. However, releaseably affixed also refers to the affixed point 235 simultaneously being weak enough such that the affixed point 235 is undone during the donning process of the garment 10; the affixed point 235 should be released without damage to the materials of the garment 10 and without the need for the wearer to manipulate the affixed point 235 more than would occur during the normal movement, or process, of physically donning the garment 10. In other words, releaseably affixed refers to the affixed point 235 being strong enough to hold the garment 10 in its donning configuration until the garment 10 is donned and will also readily release each limb of the garment 10 as the wearer inserts their arms and legs into the garment 10.
(46) As shown in
(47) In both the sleeves 18, 20 and legs 22, 24, it is the interior surfaces 101 of the limbs that are releaseably affixed together to form the donning configuration. This ensures that as the wearer inserts their legs and arms into the garment 10, the wearer will only contact the interior surface 101 of the garment 10 and will avoid contact with the exterior surface 103. As the wearer puts their feet into the shortened legs 222, 224, their foot will push against an interior surface 101 of the garment 10. In the embodiment illustrated in
(48) Similarly, in the embodiment of
(49) In the embodiment illustrated in
(50) Alternatively, or additionally, the garment 10 may be designed such that continuous portions (not shown) along the length of the interior surface 101 of the limbs may be releaseably affixed. Such continuous portions, may extend the entire length of the lower and upper segments 201, 211, 203, 213, or may be multiple continuous lengths along a portion of the segment lengths 202, 204, 212, 214.
(51) The point at which the limbs are releaseably affixed in the donning configuration may be positioned to provide a desired shortened limb 218, 220, 222, 224 configuration. For example, the garment 10 illustrated in
(52) In the same way, the embodiment illustrated in
(53) Alternative placement of the affixed point(s) 235 and resultant shortened limb donning configurations are illustrated in
(54) In
(55) One skilled in the art would recognize that different combinations of placement of one or more affixed points 235 may be utilized to provide the desired donning configuration. Various configurations of one or more affixed points 235 may be utilized to provide shortened sleeves 218, 220, shortened legs 222, 224, or both that are any shortened length 219, 223 that is desired. Preferably, the shortened sleeve length 219 will be approximately equal to or less than two-thirds of the full sleeve length 206 and the shortened leg length 223 will be approximately equal to or less than two-thirds the full leg length 216. The shortened sleeve lengths 219 may be approximately equal to or less than 50 percent of the full sleeve length 206 and the shortened leg length 223 may be approximately equal to or less than 50 percent of the full leg length 216.
(56) One skilled in the art would also recognize that the number of internal folds within the shortened limb and the orientation of those folds may be configured as desired. As discussed above, it may be desirable that the shortened limb is not allowed to intrude into the body portions 14, 16 when in the donning configuration. Also, as previously discussed, it may be desired to present more folds 251, 252 of materials to the shortened limbs in the donning configuration such that the hand or foot of the wearer is more likely to push against such folds 251, 252 when donning the garment 10 and thus prevent the wearer from prematurely pushing their hand or foot through the garment openings 92, 94, 96, 98.
(57) Again, the interior surfaces 101 of the limbs of the garment 10 are releaseably affixed in a shortened configuration to form the donning configuration of the garment 10. In the donning configuration at least a portion of the lower segment of each limb is releaseably affixed to at least a portion of the upper segment of that same limb. As discussed above, the limb is releaseably affixed in such a way that the garment 10 is held in its donning configuration during packaging, shipping, unpacking, unfolding, shaking by the wearer, and other handling that may occur up until the garment 10 is donned. When the garment 10 is donned, the affixed point 235 should then release the lower segment from the upper segment of the garment limb as the wearer inserts their leg or arm into the garment limb during the donning of the garment 10. The donning configuration of the garment 10 is released as the garment 10 is donned without the wearer having manipulate the garment 10 to any greater degree than occurs by insertion of their legs and arms into the garment 10. Additionally, the affixed point 235 should release the garment 10 from its donning configuration without damaging the garment 10.
(58) The sleeve 18 illustrated in
(59) One typical fastener 231 and cooperative fastener 233 combination, as shown in
(60) Alternatively, the garment 10 may be releaseably affixed with the use of a lone fastener 231 that releaseably affixes the upper segment to the lower segment of the interior surface 101 of the particular limb. An example of such a garment 10 utilizing a lone fastener 231 is shown in
(61) Such fasteners 231 and cooperative fasteners 233, if present, should be made of a material, and be of a type, that is compatible for the material of the garment 10, compatible with the sterilization technique utilized (if sterilization used), and appropriate for the environment in which the garment 10 is used. One skilled in the art would understand that any combination of types of fasteners 231 and cooperative fasteners 233, number of such fasteners 231, and position of such fasteners 231 may be utilized to address the particular garment 10 design and garment use that may be desired.
(62) Such a garment 10 may be packaged by any means and/or method that allows for the wearer to easily access the garment 10 for donning, while ensuring that the wearer does not touch an exterior surface 103 of the garment 10. One exemplary method of preparing the garment 10 for donning may include the first step of shortening the sleeves 18, 20 and legs 22, 24 of the garment 10. As discussed above for the garment 10 illustrated in
(63) Next, with the front side 12 of the garment 10 laying against a table, the shortened sleeves 218, 220 may then be folded toward the back side 13 of the garment. Similarly, the shortened legs 222, 224 may then be folded up toward the back side 13 of the garment 10, on top of the folded shortened sleeves 218, 220. Finally, the partially folded garment 10 may be flipped over such that the closure means 48 is facing upwards. The closure means 48 may be opened and the left and right opening flaps 50, 52 may be pulled open and around to the back 13 of the partially folded garment 10 such that only the interior surface 101 of the garment 10 is exposed on the outside of the folded garment.
(64) This method of folding of the garment 10 is only one potential method of folding the garment 10. Other methods that shortened the sleeves 218, 220 and the legs 222, 224 and fold the garment 10 such that the interior surface 101 is made available to the wearer during subsequent unfolding and donning are also contemplated. One skilled in the art would see how a different order of folding steps, numbers of folds, desired final folded dimensions, and other such considerations, may contribute to different methods of folding up the garment 10.
(65) Additionally, such garments 10 are typically laundered and dried to remove any excessive particulates that may be present from the garment manufacturing process. This step would likely need to occur before the folding steps.
(66) Once folded, the garment 10 may be packaged in any method as known to package such garments 10 to form a protective garment package to be delivered to the wearer. Typically, the folded garment 10 may be placed in a bag and the bag sealed to form a garment package. It may be desired that the garment package be sterilized by any sterilization as is known for such products. Additionally, it may be desirable that the air within the bag be removed during packaging, such that the garment is vacuum-packed, prior to such sterilization.
(67) The garment 10 may be configured such that the wearer of the garment may easily don the garment 10 without touching an exterior surface 103 of the garment and without letting any portion of the garment touch the floor. The wearer first grasps the interior surface 101 of the folded garment in such a way as to allow gravity to unfold the garment 10 into the donning configuration, such as illustrated in
(68) The wearer then inserts one of their feet into the appropriate leg (22 or 24) of the garment 10, making sure that the foot presses against the interior folds and/or the gathered opening 96, 98 of the shortened leg 222, 224. As the wearer continues to extend their leg, pressing their foot against the interior folds and/or gathered opening, the lower segment 211 of the leg 22, 24 is released from its upper segment 213. The wearer then extends their foot through the leg opening 96, 98 and engages the donning loop 36, if present. This is then repeated for the wearer's other leg. As the wearer pulls up on the body portions 14, 16 of the garment 10, the shortened legs 222, 224 of the garment 10 will lengthen to length of the wearer's legs and provide the wearer with the appropriate leg fit.
(69) Next, the wearer inserts one of their arms into the appropriate sleeve (18 or 20) of the garment 10, making sure that the hand presses against the interior folds and/or the gathered opening 92, 94 of the shortened arm 218, 220. As the wearer continues to extend their arm, pressing their hand against the interior folds and/or gathered opening 92, 94, the lower segment 201 of the arm is released from its upper segment 203. The wearer then extends their hand through the hand opening 92, 94 and engages the donning loop 36, if present. This is then repeated for the wearers other arm. As the wearer extends their arms into the sleeves 18, 20 and pulls the garment shoulders 62 over their own shoulders, the shortened sleeves 218, 220 will lengthen to the length of the wearer's arms and provide the wearer with the appropriate arm fit. The wearer then completes the donning of the garment 10 by closing the closing means 48 and securing the closure flap 49 over the closing means 48.
(70) The garment 10 may also include other additional features. In
(71) The closure means 48 of the garment 10 may include any type of fastener as are common for such protective garments. Desirably, the closure means 48 will be a mechanical closure device, such as a standard zipper for barrier protection. However, it is contemplated that other fasteners such as hook-and-loop fasteners, snaps, re-sealable tapes, or other similar fasteners may be used, depending on the level of protection required of the garment 10. Additionally, as illustrated in
(72) The garment 10 may alternatively incorporate an obliquely oriented opening with an associated fastener, across the front torso region of the garment, instead of a conventional vertical opening for entry into the garment. For example, a zipper may start at the shoulder and proceed diagonally across the torso down to the upper thigh region. This allows the torso of the garment to be opened wide. An angled zipper that starts away from the neck of the wearer may be less irritating.
(73) Colors, symbols, words, logos, or other such indicia may be employed to communicate a particular message, such as the relative level of protection, or to provide distinctive appearance as a style element. Colors may be applied to the material of the entire garment 10, individual portions of the garment 10, or as fabric piping along seams, around pockets or leggings, or in distinctive patterns. A logo denoting branding or level of protection may be located on the garment 10. Color may be added to the closure means for communication and appearance purposes.
(74) Such indicia may be utilized in the garment 10 to help the wearer identify the interior surface 101 of the garment 10, or particular area of the interior surface 101, where the wearer should grasp the garment 10 while donning the garment 10. For example, the material that is used to make the garment 10 may be of different color, or color shade, on one side versus the other side of the material. Garments made of such a material would then have a different color, or shade, on the interior surfaces of the garment versus the exterior surfaces 103. Alternatively, or additionally, a symbol or a word may be printed on the interior surface 101 of the garment 10 indicating the optimal place for the wearer to grasp the garment 10 for easy donning.
(75) Generally speaking, the manufacture of such garments may be in accordance with known automated, semi-automated, or hand assembly procedures. For example, attachment of the various portions of the garment may be achieved utilizing sewing or stitching, ultrasonic bonding, solvent welding, adhesives, thermal bonding and similar techniques.
(76) All materials used in the protective garment 10 have barrier properties that meet industrial standards for their respective designated level of protection. The garment materials are generally breathable and liquid resistant barrier materials. The breathability of the material increases the comfort of someone wearing such a garment, especially if the garment is worn under high heat index conditions, vigorous physical activity, or long periods of time. Various suitable woven and non-woven barrier materials are known and used in the art for garments such as surgical gowns, coveralls, industrial protective garments, and the like. All such materials are within the scope of the present disclosure.
(77) The material used to form the garment may be one or more bonded carded webs, webs of spunbonded fibers, webs of meltblown fibers, webs of spunlaced fibers, webs of other nonwoven materials, one or more knit or woven materials, one or more films, and combinations thereof. The material may be formed from polymers such as, for example, polyamides, polyolefins, polyesters, polyvinyl alcohols, polyurethanes, polyvinyl chlorides, polyfluorocarbons, polystyrenes, caprolactams, copolymers of ethylene and at least one vinyl monomer, copolymers of ethylene and n-butyl acrylate, and cellulosic and acrylic resins, and mixtures and blends of the same. If the material is formed from a polyolefin, the polyolefin may be polyethylene, polypropylene, polybutene, ethylene copolymers, propylene copolymers and butene copolymers.
(78) Multiple layers of seamless sheet material may be joined into a seamless laminate and used to form garments having desirable barrier properties. Laminates can be formed by combining layers of seamless sheet materials with each other and/or forming or depositing layers of such materials on each other. For example, the material may be a laminate of two or more nonwoven webs. As a further example, the material may be a laminate of at least one web of spunbonded fibers and at least one web of meltblown fibers and mixtures thereof.
(79) For example, useful multi-layer materials may be made by joining at least one web of meltblown fibers (which may include meltblown microfibers) with at least one spunbonded continuous filament web. An exemplary multi-layer seamless material useful for making the protective garment of the present invention is a nonwoven laminated fabric constructed by bonding together layers of spunbonded continuous filaments webs and webs of meltblown fibers (which may include meltblown microfibers) and may also include a bonded carded web or other nonwoven fabric.
(80) An exemplary three-layer fabric having a first outer ply of a spunbonded web, a middle ply of a meltblown web, and a second outer ply of a spunbonded web may be referred to in shorthand notation as SMS. Such fabrics are described in detail in U.S. Pat. Nos. 4,041,203, 4,374,888, and 4,753, 843, all of which patents are assigned to the Kimberly-Clark Corporation, the assignee of the present invention.
(81) An exemplary material which could be used for the manufacture of protective garment 10 is laminated fabric constructed by bonding together at least one layer of a nonwoven web with at least one layer of a film. Generally speaking, the film layer may range in thickness from about 0.25 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.
(82) Exemplary film layers include films formed from polymers which may include polyamides, polyolefins, polyesters, polyvinyl alcohols, polyurethanes, polyvinyl chlorides, polyfluorocarbons, polystyrenes, caprolactams, copolymers of ethylene and at least one vinyl monomer, copolymers of ethylene and n-butyl acrylate, and cellulosic and acrylic resins. If the film layer is made of a polyolefin, the polyolefin may be polyethylene, polypropylene, polybutene, ethylene copolymers, propylene copolymers and butene copolymers and blends of the above.
(83) The seamless sheet material of the garment 10 may have a basis weight ranging from about 15 gsm (i.e., grams per square meter) to about 300 gsm. For example, the seamless sheet material may have a basis weight ranging from about 20 gsm to about 100 gsm. Desirably, the material may have a basis weight ranging from about 20 gsm to about 75 gsm.
(84) For example, the material may be made from various forms of calendared nonwoven materials, such as Dupont Tyvek brand high-density polyethylene materials. Garments made of Tyvek have been used for hazardous environments or for general, non-hazardous, industrial use. Examples of uses for hazardous environments include protection against water-based acids, bases, salts and splashes of certain liquids, such as pesticides and herbicides. The garments also provide a reliable barrier against exposure to harmful dry particles, such as lead dust, asbestos and particles contaminated with radiation. Non-hazardous, industrial uses include wearing the garments for dirty jobs at factories, workshops, engineering plants, farms and construction sites.
(85) The resistance hydrostatic pressure (hydrohead) of the protective articles will depend, in part, on the particular kind of material from which the article is constructed. The garment may be designed to have a liquid hydrohead resistance of at least about 15, 17 or 20 millibars, up to about 180, 187, or 200 millibars, inclusive of all range combinations thereinbetween. More commonly, the garment may have a hydrohead resistance of about 25 or 30 to about 115 millibars, preferably between about 45 to about 110 millibars, and more preferably between about 50 millibars to about 95 millibars of pressure.
(86) The air permeability of the garment materials, may range from at least about 2 cubic feet per meter (cfm) up to about 47 or 50 cfm, inclusive of all range combinations thereinbetween. More typically, the air permeability may be in the range from about 5 or 10 cfm to about 43 or 45 cfm, and preferably between about 15, 17, 20, or 25 cfm to about 40 or 42 cfm.
(87) The garment may have a moisture vapor transmission rate (MVTR) of up to about 4700 g/m.sup.2/24 hours, more typically about between about 2700 or 3600 MVTR to about 4500 or 4600 MVTR. The protective garment may protect the wearer resistance of about 9-100% against dry particle barrier intrusion of a particle size of 0.3-05 microns.
(88) The garment may be made from a material that provides a barrier to dust and microparticulates (e.g., ranging in size from about 0.05-0.10 microns or larger (see, e.g., U.S. Pat. No. 5,491,753) or light-splash fluids. The materials of the garment may also be electret-treated to generate a localized electrostatic charge within the fibers of the nonwoven web (e.g., U.S. Pat. No. 5,401,446 to Tsai). For example, these materials may be treated with compositions such as Zepel and Zelec, available from E. I. du Pont De Nemours, located in Wilmington, Del.
(89) The present invention has been described in general and in detail by way of examples. Persons of skill in the art understand that the invention is not limited to the specific embodiments disclosed. Modification and variations of the general concept may be made without departing from the scope of the invention as defined by the following claims or equivalents, including, equivalent components.
