  • Patent number: 6148871
    Abstract: A textile fabric comprises a plurality of weft yarns extending generally in a weft direction and a plurality of flat film warp yarns extending generally in a warp direction. The warp yarns are interwoven with the weft yarns in a series of identical repeating units of a predetermined weave pattern. The flat film warp yarns, which are preferably between about 10 and 40 .mu.m in thickness and 0.010 and 0.025 inches in width, are preferably interwoven with the weft yarns such that, in each of the identical repeating units, the weft yarns are interwoven as coupled pairs, such that a first yarn of each of the coupled pairs follows the same interweaving pattern relative to each of the flat film warp yarns as a second yarn of that pair. This configuration, known as a "double-pick" configuration, can produce a fabric that has acceptable appearance and feel, but at a considerably lower cost than typical textile fabrics of comparable weight because of the presence of the flat film warp yarns.

  • Patent number: 5958804
    Abstract: The invention provides fabrics having improved ballistic performance and processes for making the same. The fabrics include a network of consolidated multifilament yarns formed of high strength filaments. At least a portion of the high strength filaments of the yarns, are temporarily locked together to provide a substantially stable, flattened cross-sectional configuration to the yarns. The resultant fabrics are capable of absorbing an impact from a projectile, i.e., a bullet or shrapnel, directed toward the fabric and substantially decreasing its velocity. The fabric can also provide slippage or movement of the yarns relative to one another to dissipate the energy of impact of a projectile across a greater surface area of the fabric.

    Abstract: A smooth elastic stretch fabric which is plain woven with weft and/or warp yarns that include combination yarns which comprise a partially oriented synthetic crystalline polymer yarn combined with an elastomeric core wherein the smooth fabric (i.e., a non-crepe effect) is the result of a tight weave characterized by the reciprocal of the warp apparent fractional cover (i.e., 1/WaAFC) being in the range between about 1.13 and about 2.06. The fabric is stretched, heat set and finished under particular conditions to provide the resultant fabric with an elastic stretch of more than about 10% and dimensions about equal to the as-woven dimensions.

The conductive filaments used in this process have higher elongations to break, and carpets tufted from the yarns of the process show improved anti-static properties.

  • Patent number: 5097872
    Abstract: A woven work fabric includes a first set of monofilament yarns that extend in a first direction and a second set of monofilament yarns that are interwoven with the first set of yarns and that extend in a second direction that is transverse to the first set of yarns. Each of the monofilaments in one of the sets of yarns has a cross section that has a substantially "X"-shaped configuration, and that is deformed during the weaving of the yarn sets wherein a relatively flat outer exposed surface is formed on each of the monofilament yarns in the one set of yarns.

  • Patent number: 5091247
    Abstract: Woven geotextile grid for earth reinforcement applications. The grid is formed of woven fabric which is coated with a suitable polyvinylchloride or other plastic coating. The fabric is formed of a plurality of spaced-apart pick yarn bundles which are interwoven with a plurality of spaced-apart warp yarn bundles. The pick yarn bundles are held in place in the warp yarn bundles with locking yarns which run parallel to the pick yarns and which are positioned adjacent to the edges of the pick yarn bundles. The warp yarns extend between the pick yarn bundles and locking yarns to lock the pick yarn bundles into place. A plurality of pairs of leno yarns oriented parallel to the warp yarns additionally strengthen the fabric by interlocking with one another in the spaces between pick yarn bundles and locking yarns. The result is a grid which has wide lateral and longitudinal members that lock together to form large interstices through which soil and water may penetrate.

  • Patent number: 5054524
    Abstract: A solid-color weave pattern belt comprising a weave in which warps are arranged at such a high density that wefts are substantially hidden behind the warps. The weave comprises a 2/2 twill weave having four warp threading phases with warp threading arrangement units selected from three kinds of units formed by omitting one to three warp threading phases from the four warp threading phases. A plurality of at least one warp threading arrangement units are successively adjacent to each other, thereby forming an uneven weave pattern of wefts substantially hidden behind the warps on the surface of the belt.

  • Patent number: 4926910
    Abstract: A radio-frequency reflective surface is made of a fabric woven from a yarn having an effective coefficient of thermal expansion of substantially zero over a useful temperature range. The yarn comprises a metallic filament around which non-metallic rovings are wound. The coefficients of thermal expansion of the filament and the roving material are related to each other so that mechanical strain thermally induced in the filament by changes in temperature is counteracted by mechanical strain theremally induced in the rovings. Intermodulation products at yarn intersections of the fabric are substantially zero.

  • Patent number: 4756714
    Abstract: Textile yarns are treated with a sizing composition which, when dried and cured, remains durably bound to the yarn throughout wet finishing operations and subsequent use. The sizing composition comprises an aqueous self-crosslinking emulsion copolymer derived from at least one ethylenically unsaturated monomer and a latent-crosslinking monomer. The sizing composition may also include a water soluble or dispersible film forming polymer and a reactive resin. The durable size coating beneficially contributes to both the physical and the aesthetic properties of the yarn and fabrics formed therefrom.
