Abstract:
A coated textile system comprising a fibrous substrate coated by an elastomer mixed with inorganic particles provides good drape and bending with very high cut resistance. The substrate can include conventional and/or high performance fibers. The elastomer includes particles of at least two sizes, and in embodiments three or more sizes, which fill in gaps between the largest particles and prevent a blade from pushing the particles aside and passing between them. The coating can be applied directly to the substrate, or pre-formed and adhered thereto. Particles can be pigmented, to impart a color to the textile. Pin holes formed by the particles and/or by mechanical manipulation can increase MVT. An elastomeric cover layer can enhance grip and/or reduce MVT. A plurality of layers of coated textile can be combined, in embodiments attached only about their perimeters, to provide even higher levels of cut resistance without sacrifice of bendability.

Abstract:
A vinyl floor covering is provided wherein the vinyl floor covering comprises a carrier which comprises a nonwoven layer of fibers containing thermoplastic fibers and high modulus threads extending in the longitudinal direction of the vinyl floor covering for eliminating wrinkles in the vinyl floor covering and for preventing the formation of printing errors and/or surface irregularities in the vinyl floor covering.
Abstract:
A variety of methods of improving the dyeability and printability of fabrics comprising or consisting essentially of high tenacity fibers having a tensile breaking strength of at least about 10g/Denier are disclosed. Such methods can results in fabrics, yarns, and/or fiber bundles having an improved ability to be dyed and/or printed with a printed pattern (e.g., a camouflage pattern), when compared to typical high tenacity fiber-based fabrics known in the prior art. The fabrics can have dyeability characteristics enabling them to be dyed with a variety of commercially relevant fabric dyes, such that the fabrics, after exposure to the dyes, are characterized by an essentially visually uniform dyed color density. In one embodiment, a dyeable fiber bundle, which can be utilized to form dyeable yarns and fabrics which comprises at least about 5 % of high tenacity fibers having a tensile breaking strength of at last about 10g/Denier is disclosed. Also disclosed is a method for pre-washing roll stock of fabrics comprising or consisting essentially of high tenacity fibers in order to improve the level of cut, puncture, or tear resistance of the fabrics subsequent to the pre-wash and before assembly of the fabrics into articles of apparel. A variety of fabrics including high tenacity fibers having a tensile breaking strengths of at least about 10g/Denier, as produced by or treated by such methods are also disclosed.
Abstract:
A flame-retardant coated fabric article of a single layer of fabric containing glass fibers and natural or synthetic fibers one side of which is covered by a thermoplastic polyvinyl halide composition to impart the desired diapability, hand, and tailorability properties to the article. The glass fibers provide strength to the article so that, when the article placed under tension forces and exposed to fire or a flame, it does not tear apart due to the tension forces as the coating burns, thus providing a barrier to the penetration of flame through the article. The coating also is capable of forming a char which contributes to the effectiveness of the flame barrier.
Abstract:
A shrapnel containment system is provided which is adapted to be installed at an interior of a building wall to contain shrapnel from a blast, the system including a panel made of a layer of elastomeric material and fastener elements to fasten the layer to a wall of a structure, with the panel optionally including a fabric reinforcing layer. A method for producing the panel is also provided.
Abstract:
An asphalt coated structural article comprises a substrate having an ionic charge coated on one side with a layer of asphaltic material and coated on the other side with a coating having essentially the same ionic charge as the substrate. The present invention is a waterproofing barrier which may be used as a roofing underlayment for concrete files or to waterproof the basement walls of a building structure.
Abstract:
The present disclosure describes puncture-resistant fabric layers comprising woven fabrics with unique, densely-woven structures. For example, such a fabric layer ca comprise a high cover factor woven fabric having a fill yarn cover factor of at least about 75 % of full and a warp yarn cover factor of at least about 100 % of full formed of a plurality of fill yarns and a plurality of warp yarns, wherein the weight per unit length of the fill yarns is less than the weight per unit length of the warp yarns. Such constructions can, in some embodiments, consist essentially of high tenacity fibers having a tensile breaking strength of at least about 10g/Denier. Such high cover, small fill yarn constructions enable the disclosed fabrics to be woven to have a decreased overall weight per unit surface area and an improved tensile balance, when compared to known high cover factor, densely woven fabric constructions. Also disclosed are various techniques for forming light weight yarns comprising or consisting essentially of high tenacity fibers for forming the small fill yarns and/or warp yarns of the high cover factor, small fill yarn-constructed fabrics disclosed. The high cover factor, small fill yarn-constructed woven fabrics can, in some embodiments, comprise or consist essentially of natural and/or synthetic fibers having a tensile breaking strength less than about 10 g/Denier, yielding densely woven fabrics with improved puncture, cut, and tear resistance when compared to fabrics formed of the same materials but with conventional woven constructions.
Abstract:
A variety of embodiments of layered and laminated fabric systems, each, preferably, including a puncture-resistant layer are disclosed. The puncture-resistant layer(s) of the layered systems can, in some embodiments, comprise or consist essentially of high tenacity fibers having a tensile breaking strength of at least about 10 g/Denier. The puncture-resistant layer(s) can be combined with one or more additional layers providing one or more desirable attributes of an article of apparel for use in, for example, rugged outerwear (e.g., dyeability, printability, soft hand, breatheability, abrasion resistance, etc.). The puncture-resistant layers can comprise fabrics or non fabrics and, when comprising a fabric, can comprise a woven or non-woven fabric (e.g., felts and knitted fabrics). In some embodiments, puncture-resistant layers of the multi-layer constructions and systems can comprise intimate blend fabrics comprising two or more different fiber types and/or high cover factor, small fill yarn fabrics or, in other embodiments, can comprise one or more conventionally constructed puncture-resistant layer(s).
