Definitions

  • the invention relates to a human wearable glove made of a composite, protective material, and more particularly to a human wearable glove made of a combination of layers of stainless steel mesh and layers of woven, para-aramid fibers and the use of that composite fabric in constructing protective garments.
  • Fabrics woven from para-aramid synthetic fibers such as, but not limited to, KevlarTM, display exceptional resistance to ballistic puncture and have been used successfully to construct light weight, bullet proof body armor.
  • the materials are, however, only of average resistance to cut and slash attacks and to puncture by needles.
  • the para-aramid based body armor therefore, provides good protection against gun attacks, but is not particularly effective against knife or needle threats.
  • What is needed is a light-weight fabric that provides a combination of high resistance to ballistic puncture, cut and slash attacks and puncture attacks, and which can be readily used to fabricate light weight, flexible garments such as, but not limited to, gloves and attack proof vests.
  • the projectile is eventually decelerated to harmless velocity through a combination of transfer of momentum to the masses and the elastic and plastic tensile deformation of the fibers.
  • One or more layers of the composite material can be assembled to form body protective armor (“bullet-proof vest”) or property protective armor, the number and characteristics of the layers being adjusted according to the specific ballistic threat anticipated.
  • the present invention pertains to an inventive glove made of a composite, protective material, as disclosed herein.
  • the unexpectedly effective composite material of the present invention therefore, combines high levels of ballistic, cut, stab and needle protection while being sufficiently lightweight and flexible for use in wearable protective garments.
  • one or microflex layers may be placed in proximity with one or more layers of metallic mesh layer, sandwiched between an inner and an outer protective layer that may be joined at the periphery of the protective layers.
  • the microflex layers are preferably made of a woven para-aramid yarn, where the individual fibers in the yarn comprise fibers having a denier of less than or equal to 2 dtex and more preferably a denier of 0.55 dtex.
  • the para-aramid fibers are preferably comprised of poly-p-phenylene terephthalamide and may have a tenacity of at least 10 cN/dtex, an elongation at break of at least 2.7% and an initial modulus of at least 300 cN/dtex, and may be formed into a yarn of 500 or more fibers for weaving.
  • the metallic mesh layers are preferably woven from stainless steel fibers having a diameter of 0.2 mm or less and may have a mesh aperture of 0.45 mm or less.
  • the number and arrangement of the micromesh and metallic mesh layers may be adjusted in various ways to suit the material for its use in the manufacture of various wearable protective garments such as, but not limited to, gloves, attack resistant vests, protective trousers and protective leggings.
  • Figure 1 shows a schematic cut-away isometric view of the layers of a protective, composite fabric 105 as used in one embodiment of the present invention.
  • the protective, composite fabric 105 may, for instance, have a microflex fabric layer 120 adjacent to a metal mesh layer 125 with both layers sandwiched between intermediate layers 122.
  • the intermediate layers 122 may, for instance, be an outer protective layer 115 and an inner protective layer 110.
  • the inner and outer protective layers may be any fabric suitable for wearing in a garment such as, but not limited to, a fabric woven from cotton, wool, silk, linen, polyester or some combination thereof.
  • the microflex fabric layer 120 is preferably made of woven para-aramid yarn. Para-aramid yarns are well-known and sold by, for instance, E. I.
  • Woven para-aramid fabrics have become widely used in body-armor because of their high resistance to ballistic penetration. Such fabrics are, however, susceptible to puncture type penetration, particularly cut and slash penetration and to needle stick penetration.
  • the metal mesh layer 125 is preferably a woven metallic mesh, and more preferably a woven mesh of stainless steel fibers having a diameter of 0.2 mm or less and a mesh aperture of 0.45 mm or less.
  • a mesh has been found to have good resistance to cut and slash penetration and to needle stick penetration, and has been used in protective garments such as, but not limited to, protective gloves, as described in, for instance, US Patent 6,581,212 issued to Andresen on June 24, 2003 .
  • the number of metal mesh layers 125 of the type described above may be needed to provide, for instance, adequate puncture penetration may result in garments such as, but not limited to, protective gloves, that may not have as much flexibility as desired or may be more costly to produce than desired.
  • KevlarTM fabric used for bullet proof vests in, for instance, made from Kevlar 29 yarn.
  • Kevlar 29 yarn is made of approximately 1000 fibers wound together to form a yarn having a denier of approximately 1,500 dtex.
  • the unit "dtex” is an internationally recognized measure of yarn or filament size and is the weight in grams of 10,000 meters of the yarn or filament).
  • a 1000 filament yarn having a denier of 1,500 dtex implies a denier for the individual fibers of about 1.5 dtex.
  • Teijin Aramid's recommended yarn for weaving into bullet proof vest is their TwaronTM Microfilament yarn.
  • Their 2040 Microfilament fiber for instance, consists of 500 fibers wound together for a yarn having a dernier of 550 dtex, implying a fiber dernier of 1.1 dtex. They also supply an Ultra Micro version of TwaronTM that is a yarn having 500 filaments and a fiber dernier of 550 dtex, implying a filament dernier of 0.55 dtex.
  • the puncture resistance synergy of the microflex fabric layers 120 and the metal mesh layers 125 may be more pronounced when the fiber size of the para-aramid fibers is smallest. This may be indicative of some interaction occurring between the two layers during a puncture attack.
  • This interaction may, for instance, be the para-aramid fibers being forced through or past the metal fibers of the mesh.
  • the kinetic energy expended in stretching the para-aramid fibers through the mesh may be the explanation for the synergistic behavior of the two layers that produces the surprisingly better puncture resistance of when the two are combined as a composite material.
  • the para-aramid fibers may, therefore, be poly-p-phenylene terephthalamide fibers having a fiber dernier of 2 dtex or less that may be bundled, for weaving, into a yarn having 500 or more fibers, with the yarn having a strength at break of 200 N or more, a tenacity at break of 2.3 mN/tex or more and an elongation at break of between 3.4% and 3.8%.
  • the fiber dernier may be 1.1 dtex or less, and a most preferred embodiment may have a fiber dernier of 0.55 dtex or less.
  • the microflex fabric layers 120 and the metal mesh layers 125 may be sandwiched between an outer protective layer 115 and an inner protective layer 110, and the inner and outer protective layers may be joined at a periphery of a garment piece by, for instance, stitching or by some other joining mechanism such as, but not limited to, gluing, welding, stapling or some combination thereof.
  • Figure 2 shows a schematic plan view of a protective glove 170 of one embodiment of the present invention, and a schematic cross-section of a selected portion 180 of the glove 170.
  • the partial cross section 180 of the glove is shown as taken on a line 175.
  • the partial cross section 180 of a glove shows a top portion 185 of a glove and a lower portion 190 of a glove separated by a space 195 for a hand.
  • the top portion 185 of the glove is shown as having an outer protective layer 205 and an inner protective layer 210 between which are sandwiched a plurality of metal mesh layers 125 and a microflex fabric layer 120.
  • the lower portion 190 of a glove is similarly shown with the metal mesh layers 125 and the microflex fabric layers 120 sandwiched between an outer protective layer 205 and an inner protective layer 210.
  • the inner protective layer 210 is shown closest to the space 195 for a hand and the microflex fabric layers 120 are shown proximate to the inner protective layer 210.
  • Such an arrangement may, for instance, provide a material well suited to resisting puncture attack from the outside of the glove.
  • Figure 2 shows four metal mesh layers 125 and one microflex fabric layers 120.
  • the composite material may, for instance, have a plurality of microflex fabric layers 120 and metal mesh layers 125 that may be alternated with each other. Such an arrangement may, for instance, increase the hypothesized synergy between the layers described above.
  • the composite material may, for instance, have one or more layers of microflex fabric layers 120 adjacent to both the outer protective layer 205 and the inner protective layer 210 on either or both of the top portion 185 of a glove and the lower portion 190 of a glove. Such an arrangement may, for instance, increase the resistance of the inside of the glove to rupturing through flexing.
  • Figure 3 shows a schematic, plan view of an elephant-pattern 130 cut-out of one embodiment of the present invention.
  • the elephant-pattern 130 may, for instance, have a first palm region 135 with an integral thumb extension 140 that may be attached via a lower palm edge 155, to a second palm region 145 having one or more finger extensions 150.
  • the attachment of the first palm region 135 to the second palm region 145 may, for instance, be via a lower palm edge 155.
  • the fabric to be cut into the elephant-pattern 130 may be arranged such that one or more of the finger extensions 150 are bias-cut 165 with respect to a direction 160 of that finger extension. Such an arrangement may have the advantage of increased flexibility of the finger portion of the glove.
  • the shape is such that when the fabric is arranged such that one or more of the finger extensions is bias-cut with respect to the direction of that finger extension, the thumb extension 140 is also bias cut with respect to a direction 162 of the thumb extension.
  • the bias-cut may only be used for the metal mesh layers 125 as bias-cutting tends to produce more waste. There may, however, be situations where the additional flexibility introduced by bias-cutting makes it a preferred method even for one or more of the microflex fabric layers 120. For instance, in an application required multiple microflex fabric layers 120, the combined effect of many layers may be to provide a fabric that is too stiff in a particular direction and bias-cutting of one or more of the microflex fabric layers 120 may provide a more acceptable and wearable garment.
  • Figure 4 shows a schematic, plan view of a folded, elephant pattern layer 215 of one embodiment of the present invention.
  • the folded, elephant pattern layer 215 is shown folded along a lower palm edge 155 that joins the two palm regions of the elephant pattern so that the structure is now ready to be used in a glove.
  • the folded, elephant pattern layer 215 has the added advantage that the palm region of the glove, which may be the most vulnerable portion of the glove with respect to puncture, has a double layer of metal mesh.
  • Figure 5 shows a schematic view of a bias-cut on a woven fabric 230.
  • the bias-cut 165 is at approximately forty-five degrees with respect to both the warp thread 220 and the weft thread 225 of the woven fabric.
  • Figure 6 shows a schematic, exploded isometric view of the components of a portion of a protective vest 260 of one embodiment of the present invention.
  • a chest or back portion of a protective vest 260 may have 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.
  • this arrangement may provide good protection against a ballistic attack on the wearer.
  • the outer and inner protective layers may be made of a suitably wearable fabric such as, but not limited to, cotton, denim, wool, silk, linen, bamboo, or some combination thereof.
  • the plurality of microflex layers 240 may be joined to each other by stitching extending across the interior 255.
  • the plurality of metal mesh layers 245 may, in contrast, be joined to each other by being peripherally sewn 250.
  • the joining may also or instead be accomplished by a means such as, but not limited to, gluing, welding, stapling, or some combination thereof.
  • the plurality of metal mesh layers 245 may also have one or more microflex fabric layers 120 attached to them by being peripherally sewn 250. These layers may be on either side of the plurality of metal mesh layers 245 or on both sides.
  • the microflex fabric layers 120 peripherally attached to the peripherally sewn 250 may, for instance, provide enhanced protection against puncture attacks such as, but not limited to, stab, cut, slash and needle attacks, or some combination thereof.
  • microflex fabric layers 120 and between 8 and 12 metal mesh layers 125 there may be between 20 and 28 microflex fabric layers 120 and between 8 and 12 metal mesh layers 125, and in a more preferred embodiment there are 24 microflex fabric layers 120 and 10 metal mesh layers 125.
  • the protective, composite fabric illustrated in Figure 6 and described above may be used in a variety of other protective garments.
  • trousers or legging made incorporating such a material may, for instance, offer significant protection against puncture attacks such as those of industrial cutting machinery such as, but not limited to, a chain-saw.
  • the material, or variants of it may be incorporated into other items of protective apparel such as, but not limited to, shoes, boots, gloves, head-gear or sleeves.
  • Figure 7 shows a schematic plan view of an inter-woven para-aramid/metal fiber fabric 265 of one embodiment of the present invention.
  • Para-aramid fibers typically have a tensile strength of about 36% more than an equivalent dimensioned steel fiber. As para-aramids are typically only about 18% as dense as steel, this gives them a tensile strength advantage of about a factor of 5, which is why they are often cited as being "five times as strong as steel". However, para-amid fiber typically have a shear strength that is only about 24% of that of steel. This means that they are much easier to cut or to stab through with either a sharp instrument or a needle. A conjecture for the unexpected 30-40% increase in the puncture resistance when microflex fabric layers 120 are combined with metal mesh layers 125 is that the para-amid fibers are being bent and then stretched through the metal mesh. This would allow a fraction of their superior tensile strength to come into effect even in resisting a low velocity puncture, cut or needle attack.
  • a similar synergy of the properties of metal and para-aramid fibers may, therefore, also be possible by weaving the fibers into a single layer of fabric.
  • the fabric has alternating warp para-aramid yarn fibers 272 and warp metal fibers 277 as well as alternating weft para-aramid yarn fibers 270 and weft metal fibers 275.
  • alternating warp para-aramid yarn fibers 272 and warp metal fibers 277 as well as alternating weft para-aramid yarn fibers 270 and weft metal fibers 275.
  • alternate types of weaving could also be used to create such a composite such as, but not limited to, having all para-aramid yarn weft fibers and all metal warp fibers, or vice versa.
  • the inter-woven para-aramid/metal fiber fabric 265 may be made of para-aramid yarn made of a plurality of individual poly-p-phenylene terephthalamide fibers having a denier of 2 dtex or less, while the metal fibers may be stainless steel fibers having a diameter of 0.2 mm or less.
  • the inter-woven para-aramid/metal fiber fabric 265 may be woven such the mesh aperture is 0.45 mm or less.
  • Figure 8 shows a schematic, plan view of a folded, elephant pattern layer of one embodiment of the present invention having a truncated thumb extension and truncated finger extensions.
  • the folded, elephant pattern layer 215 of Figure 8 is shown as having a first palm region 135 with a truncated thumb extension 142.
  • the pattern may be folded at a lower palm edge 155 that may be connected to a second palm region (not shown in this view) that may have one or more finger extensions 150 and one or more truncated finger extensions 152 attached to it.
  • a purpose of having one or more metal mesh layers or one more para-aramid layers of the protective material having either a truncated finger or thumb extension may be to allow additional flexibility of a wearer's corresponding digits.
  • the glove may, for instance, be used by an agent wanting to use a firearm while wearing the glove. Having additional flexibility and less bulk in the thumb and index fingers of a glove may, for instance, allow a wearer to hold and fire a pistol more easily.
  • Figure 9A shows a schematic, plan view of a fan, 3-piece glove pattern 280 cut-out of one embodiment of the present invention.
  • the fan, 3-piece glove pattern 280 may have a thumb piece of a fan glove pattern 281, a fingers piece of a fan glove pattern 282 and a palm piece of a fan glove pattern 283.
  • the fan, 3-piece glove pattern 280 may be used to cut either microflex fabric layers or metal mesh layers, or both.
  • the fan, 3-piece glove pattern 280 pieces may be arranged such that either, or both, of the thumb and finger extensions are bias-cut for reasons such as those described above.
  • Figure 9B shows a schematic, plan view of an assembled fan, 3-piece glove pattern 285 of one embodiment of the present invention.
  • the thumb piece 281, the fingers piece 282 and the palm piece 283 may be assembled together by any suitable means such as, but not limited to, stitching, gluing, stapling, welding, spot gluing, spot stitching, spot welding or some combination thereof.
  • the pieces may also, or instead, be held in place by suitably shaped inner and outer protective layers that may be joined peripherally by, for instance, stitching, or which may be joined by stitching that extends across the interior of the pattern.
  • Figure 10A shows a schematic, plan view of a turkey, 3-piece glove pattern 290 cut-out of one embodiment of the present invention.
  • the turkey, 3-piece glove pattern 290 may have a thumb piece of a turkey glove pattern 291, a fingers piece of a turkey glove pattern 292 and a palm piece of a turkey glove pattern 293.
  • the fan, 3-piece glove pattern 290 may be used to cut either microflex fabric layers or metal mesh layers, or both.
  • the turkey, 3-piece glove pattern 290 pieces may be arranged such that either, or both, of the thumb and finger extensions are bias-cut for reasons such as those described above.
  • Figure 10B shows a schematic, plan view of an assembled turkey, 3-piece glove pattern second pivot 295 of one embodiment of the present invention.

  • the pieces may also, or instead, be held in place by suitably shaped inner and outer protective layers that may be joined peripherally by, for instance, stitching, or which may be joined by stitching that extends across the interior of the pattern.
  • the inner and outer linings may also be joined directly to the inner and outer groups of fabric bundles.
  • the inner and outer microflex bundles may be made of microflex fabric layers of woven para-aramid yarn, and may comprise para-aramid yarn having some or all of the characteristics of the types of para-aramid yarns and fibers detailed above.
  • the inner and outer metal mesh bundles may be made of woven stainless steel fibers, and may comprise metal mesh layers having fiber composition and characteristics of some or all of the metal meshes described above.
  • each of the inner and outer microflex bundles and the inner and outer metal mesh bundle may have 3 to 8 layers of fabric.
  • each of the inner and outer microflex bundles and the inner and outer metal mesh bundle may have 5 layers of fabric, with the microflex layers being woven from para-aramid fibers that may be poly-p-phenylene terephthalamide fibers having a fiber dernier of 2 dtex or less that may be bundled, for weaving, into a yarn having 500 or more fibers, and the metal mesh layer being made of woven mesh of stainless steel fibers having a diameter of 0.2 mm or less and a mesh aperture of 0.45 mm or less.
  • the protective pants 305 may include regions of extra protection such as, but not limited to, the knee region of additional protection 310 and/or the crotch region of additional protection 315. Having regions of extra protection may, for instance, allow garments to be made cost effectively while providing the desired levels of protection in the regions most in need of protection.
