  The best mode for carrying out the present invention will be described below with reference to the drawings. The same elements in the various figures are given the same reference numerals.

  Reference will now be made in detail to various embodiments of the invention. Such embodiments are provided for illustration of the invention and are not intended to limit the invention. Indeed, those skilled in the art will appreciate that various modifications and variations can be made by reading this specification and viewing the drawings.

  FIG. 1 shows a schematic cutaway perspective view of a layer of protective composite fabric 105 according to one embodiment of the present invention.

  The protective composite fabric 105 can have, for example, a microflex fabric layer 120 adjacent to a metal mesh layer 125, with both layers sandwiched between intermediate layers 122.

  The intermediate layer 122 can be, for example, the outer protective layer 115 and the inner protective layer 110. The inner and outer protective layers shall be any fabric suitable for wearing as clothing, including but not limited to fabrics woven from cotton, wool, silk, linen, polyester or combinations thereof. Can do.

  In a preferred embodiment, the microflex fabric layer 120 is preferably made of woven para-aramid yarn. Para-aramid yarn is well known and is trade name Kevlar ™, E.I. in Wilmington, Delaware. I. sold by du Pont de Nemours and Company and sold by Teijin Aramid, Arnhem, the Netherlands under the trade name Twaron ™. Woven para-aramid fabrics are widely used in bulletproof vests because of their high resistance to ballistic intrusion. However, such fabrics are susceptible to puncture-type penetration, particularly cutting and tearing penetration and needle penetration.

  The metal mesh layer 125 is preferably a woven metal mesh, more preferably a woven mesh of stainless steel fibers having a diameter of 0.2 mm or less and a mesh opening of 0.45 mm or less. Such a mesh has been found to have good resistance to cut and tear penetration and needle penetration, for example against Andrewsen on June 24, 2003, which is incorporated herein by reference in its entirety. Although it is a protective glove etc. which are described in the US Patent 6,581,212 issued, it is used for the protective clothing which is not limited to this. However, the number of metal mesh layers 125 of the type described above that may be required, for example, to provide adequate puncture penetration, is not as flexible as desired or is more difficult to manufacture. It can result in clothing that can be expensive, such as but not limited to protective gloves.

  In considering a method of improving protective clothing such as gloves, it has been found that a trial fabric combination combining a microflex fabric layer 120 and a metal mesh layer 125 has unexpected properties. It was found that the fracture resistance of the combined layers was 30-40% greater than expected from the additive combination of the fracture resistance of the two individual layers. This surprising and unexpected discovery makes it possible to build lightweight, cheap and more likely garments from composite materials.

  The exact mechanism of this unexpected improvement in the material properties of the composite material may not yet be fully understood, but several factors can be important.

  It is well known that the ballistic stopping force of the polyaramid material is a result of absorbing the kinetic energy of the flying object that collides. For example, when a bullet hits the fabric, the polyaramid strands break and absorb kinetic energy as they try to penetrate the material. The strand essentially adheres to the bullet and absorbs the kinetic energy of the bullet as it is stretched to the point of failure. In order to maximize the interaction between the bullet and the material, polyaramid fabric manufacturers try to make the polyaramid fibers as small as possible to increase the “working surface” of the fibers that interact with the bullets. To do.

  A preferred Kevlar® fabric for use in a bulletproof vest is made, for example, from Kevlar® 29 yarn. Kevlar 29 yarn is made of about 1000 fibers wound together to form a yarn having a denier of about 1,500 dtex. ("Denier" is a standard measurement of filament dimensions and is a term used more loosely simply as "filament size." The unit "dtex" is an internationally recognized dimension of yarn or filament. Scale, the weight of a yarn or filament in grams of 10,000 meters). A 1000 filament yarn with a 1500 dtex denier implies that the individual fiber denier is about 1.5 dtex.

  Yarn for weaving bulletproof vests recommended by Teijin Aramid is the company's Twaron ™ microfilament yarn. The company's 2040 microfilament fiber consists of, for example, 500 fibers, wound together into a yarn with a 550 dtex denier, which means the fiber denier is 1.1 dtex. The company also supplies an ultra micro version of Twaron ™, a yarn with 500 filaments and 550 dtex fiber denier, which means that the filament denier is 0.55 dtex. The synergistic effect of the puncture resistance of the microflex fabric layer 120 and the metal mesh layer 125 may be more pronounced when the fiber size of the para-aramid fiber is minimal. This may suggest some kind of interaction that occurs between the two layers during a puncture attack. This interaction is, for example, that para-aramid fibers penetrate or pass through the metal fibers of the mesh. The kinetic energy consumed in stretching the para-aramid fibers through the mesh may be an explanation of the synergistic behavior of the two layers that results in a surprisingly good puncture resistance when the two layers are combined as a composite material.

  Thus, in a preferred embodiment of the present invention, the para-aramid fiber is a poly-p-phenylene terephthalamide fiber having a fiber denier of 2 dtex or less, which is bundled into yarns having 500 or more fibers for weaving. The yarn has a strength at break of 200 N or more, a tensile strength at break of 2.3 mN / tex or more and an elongation at break of 3.4% to 3.8%. In a more preferred embodiment of the invention, the fiber denier can be 1.1 dtex or less, and the most preferred embodiment can have a fiber denier of 0.55 dtex or less.

  In a preferred embodiment, the microflex fabric layer 120 and the metal mesh layer 125 can be sandwiched between the outer protective layer 115 and the inner protective layer 110, the inner protective layer and the outer protective layer being sewn or bonded. Can be secured by other joining mechanisms such as welding, stapling, or combinations thereof.

  FIG. 2 shows a schematic plan view of protective glove 170 and a schematic cross-sectional view of selected portion 180 of glove 170 according to one embodiment of the present invention.

  A partial cross section 180 of the glove is shown as taken on line 175. The glove partial cross section 180 shows a glove upper portion 185 and a glove lower portion 190 separated by a space 195 for the hand. The top 185 of the glove is shown as having an outer protective layer 205 and an inner protective layer 210 with a plurality of metal mesh layers 125 and microflex fabric layers 120 sandwiched therebetween. The lower portion 190 of the glove is also shown with the metal mesh layer 125 and the microflex fabric layer 120 sandwiched between the outer protective layer 205 and the inner protective layer 210. In both the top and bottom of the glove, the inner protective layer 210 is shown closest to the hand space 195 and the microflex fabric layer 120 is shown proximate to the inner protective layer 210. Such an arrangement can provide a material suitable for resisting a puncture attack from the outside of the glove, for example.

  FIG. 2 shows four metal mesh layers 125 and one microflex fabric layer 120.

  Such an arrangement can result in an economical glove that meets a specific performance level, such as, but not limited to, the EN 388 test for abrasion resistance, blade cutting resistance, tear resistance and puncture resistance. There can be other arrangements that can be more advantageous in terms of factors such as cost, performance, flexibility and comfort, or some combination thereof.

  The composite material can have, for example, a plurality of microflex fabric layers 120 and metal mesh layers 125 that are alternately arranged with each other. Such an arrangement can, for example, increase the assumed synergy between the above layers.

  The composite can have, for example, one or more microflex fabric layers 120 adjacent to both the outer protective layer 205 and the inner protective layer 210 of either or both of the glove top 185 and glove lower portion 190. Such an arrangement can increase resistance to rupture inside the glove due to bending, for example.

  FIG. 3 shows a schematic plan view of the cut-out of the image 130 according to one embodiment of the present invention.

  The elephant form 130 includes, for example, a first palm having an integral thumb extension 140 that can be attached to a second palm region 145 having one or more finger extensions 150 via a lower palm edge 155. Region 135 may be included. The attachment of the first palm region 135 to the second palm region 145 can be performed, for example, via the lower palm edge 155.

  In a preferred embodiment of the present invention, the fabric cut into the elephant 130 can be positioned such that one or more finger extensions 150 are biased 165 with respect to the direction 160 of the finger extensions. Such a configuration has the advantage of increasing the flexibility of the fingers of the glove.

  In a preferred embodiment of the elephant form 130, the shape is such that when the fabric is positioned such that one or more finger extensions are biased relative to the direction of the finger extension, the thumb extension 140 is also of the thumb extension. It is like being biased with respect to direction 162.

  In preferred embodiments, bias cutting is used only for metal mesh layer 125 because bias cutting tends to generate more waste. However, there may be situations where the additional flexibility provided by bias cutting is a preferred method even for one or more microflex fabric layers 120. For example, in applications that require multiple microflex fabric layers 120, the combined effect of many layers can provide a fabric that is too strong in a particular direction, and bias of one or more microflex fabric layers 120 can occur. Trimming can provide a more acceptable and wearable garment.

  FIG. 4 shows a schematic plan view of the folded elephant morphology layer 215 of one embodiment of the present invention.

  The folded elephant morph layer 215 is shown as a structure that is folded along the lower palm edge 155 joining the two palm regions of the elephant form and is ready for use in a glove. The folded elephant morphology layer 215 has the additional advantage that the palm region of the glove, which can be the most vulnerable part of the glove to puncture, has a double layer of metal mesh.

  FIG. 5 shows a schematic diagram of bias cutting on the woven fabric 230.

  As shown, the bias cut 165 is about 45 degrees for both the warp yarn 220 and the weft yarn 225 of the woven fabric.

  FIG. 6 shows a schematic exploded perspective view of some components of the protective vest 260 of one embodiment of the present invention.

  As shown in FIG. 6, the chest or back of the protective vest 260 includes an outer protective layer 115, a plurality of microflex layers 240 adjacent to the outer protective layer 115, a plurality of metal mesh layers 245, and an inner protective layer 110. Can have.

  If the garment is worn with the inner protective layer 110 closest to the wearer, this arrangement may provide good protection against ballistic attacks on the wearer.

  The outer and inner protective layers can be made of a suitable wearable fabric such as but not limited to cotton, denim, wool, silk, linen, bamboo, or combinations thereof.

  The plurality of microflex layers 240 can be joined together by stitches that extend across the interior 255. In contrast, a plurality of metal mesh layers 245 can be joined together by peripheral stitching 250. Bonding can also be accomplished by means such as, but not limited to, gluing, welding, stapling, or combinations thereof.

  In a preferred embodiment, the plurality of metal mesh layers 24 can also have one or more microflex fabric layers 120 attached to them by peripheral stitches 250. These layers can be on either side or on both sides of the plurality of metal mesh layers 245. The microflex fabric layer 120 attached to the peripheral stitch 250 can provide enhanced protection against puncture attacks, such as piercing, cutting, tearing and needle attacks, or combinations thereof.

  In a preferred embodiment of the present invention, there can be between 20 and 28 layers of microflex fabric layer 120 and between 8 and 12 layers of metal mesh layer 125, and in a more preferred embodiment, 24 layers of micro layers. There are a flex fabric layer 120 and ten metal mesh layers 125.

  However, those skilled in the art will appreciate that the protective composite fabric shown in FIG. 6 and described above can be used in a variety of other protective clothing. For example, trousers or leggings incorporating such materials can provide significant protection against puncture attacks such as, for example, but not limited to, an industrial cutting machine, such as a chainsaw. Similarly, this material or variations thereof can be incorporated into other protective clothing items such as, but not limited to, shoes, boots, gloves, headgear or sleeves.

  FIG. 7 shows a schematic plan view of para-aramid / metal fiber cloth 265 according to one embodiment of the present invention.

  As described above, the Applicant has found an unexpected 30-40% increase in puncture resistance when the microflex fabric layer 120 is combined with the metal mesh layer 125. One speculation is that this unexpected increase is due to such a combination, and even during slow drilling, more of the para-aramid fibers are not sheared but broken into the longitudinal axis of the fibers. Which results in being stretched along or broken.

  Para-aramid fibers typically have a tensile strength that is about 36% higher than steel fibers of comparable dimensions. Para-aramid typically has only a density of about 18% that of steel, thus providing the advantage of a tensile strength of about 5 times, which is why it is often referred to as "5 times the strength of steel". However, paraamide fibers typically have a shear strength of only about 24% of the shear strength of steel. This means that it is very easy to cut or tear with a sharp instrument or needle. The expectation for an unexpected 30-40% increase in puncture resistance when the microflex fabric layer 120 is combined with the metal mesh layer 125 is that the paraamide fibers are bent and then stretched through the metal mesh. Thereby, a part of the excellent tensile strength of the para-aramid fiber is effective even for low-speed puncture, cutting or needle attack.

  Thus, a similar synergy of the properties of metal and para-aramid fibers is possible by weaving the fibers into a single layer fabric.

  In the interwoven para-aramid / metal fiber cloth 265 shown in FIG. 7, the cloth has warp para-aramid yarn fibers 272 and warp metal fibers 277 alternately, and alternately weft para-aramid yarn fibers 270 and weft metal fibers 275. Have However, those skilled in the art can use composites of alternative types to make composite materials that are all, but not limited to, all weft yarns are para-aramid fibers and all warp yarns are metal fibers, or vice versa. . In addition to the plain weave shape shown in FIG. 7, basket weave, twill weave, or statin weave, or combinations thereof, as advantageous results for protection to material ratio or cost advantage may be obtained. Other well-known weave shapes can be used without limitation.

  In a preferred embodiment, the interwoven para-aramid / metal fiber woven fabric 265 can be made from para-aramid yarns consisting of a plurality of individual poly-p-phenylene terephthalamide fibers having a denier of 2 dtex or less, wherein the metal fibers are: Stainless steel fibers having a diameter of 0.2 mm or less can be used.

  In a further preferred embodiment of the present invention, the interwoven para-aramid / metal fiber woven fabric 265 can be woven so that the mesh opening is 0.45 mm or less.

  FIG. 8 shows a schematic plan view of the folded elephant morphological layer of one embodiment of the present invention having a truncated thumb extension and a truncated finger extension.

  The folded elephant morphological layer 215 of FIG. 8 is shown as having a first palm region 135 having a truncated thumb extension 142. This configuration connects to a second palm region (not shown in this view) that can have one or more finger extensions 150 and one or more fringe finger extensions 152 attached thereto. Can be folded at the lower palm edge 155.

  The purpose of having one or more metal mesh layers or one or more para-aramid layers of protective material with either a truncated finger extension or a truncated thumb extension is to provide additional flexibility of the wearer's corresponding finger. It can be possible. The gloves can be used, for example, by an investigator who wants to use a gun while wearing gloves. Having more flexibility and less bulk on the glove thumb and forefinger, for example, allows the wearer to more easily hold and fire the pistol.

  In an alternative version of a glove with a fringe guard, there may be additional material portions that are sized and shaped to cover the remaining portion of the thumb but to be separated from the remaining elephant form. In this way, flexibility can be maintained while providing protection for most of the thumb and fingers.

  FIG. 9A shows a schematic plan view of a fan-shaped three-point glove form 280 of one embodiment of the present invention.

  As shown, the three-point glove form 280 can have a thumb piece in a fan glove form 281, a finger piece in a fan glove form 282 and a palm piece in a fan glove form 283. The fan-shaped three-point glove form 280 can be used to cut either or both of the microflex fabric layer or the metal mesh layer. In a preferred embodiment, the fan-shaped three-point glove configuration 280 can be arranged such that either or both of the thumb extension and the finger extension are biased for reasons described above.

  FIG. 9B shows a schematic plan view of an assembled fan-shaped three-point glove shape 285 of one embodiment of the present invention. Thumb piece 281, finger piece 282 and palm piece 283 may be stitched, glued, stapled, welded, spot glued, spot stitched, spot welded or any combination thereof, by any suitable means, including but not limited to: . These pieces can be held in place by appropriately shaped inner and outer protective layers that can additionally or alternatively be joined to the perimeter, for example by means of stitches, or can be joined by stitching extending across the interior of the shape. Can be done.
