摘要:
A composite fabric, multi-layer protective panel alternative to an exclusively fine denier, continuous filament yarn protective fabric, multi-layer protective panel. Fabric layers consist of warp and fill sheets of continuous filament yarn of relatively higher denier at a relatively lower cover factor that have their yarns interlocked in a woven pattern by overlapping warp and fill sheets of staple yarns of relatively lower denier, thus raising effective cover factor. Staple yarns have a conspicuous amount of hairiness for greater yarn stability. Ballistic performance is enhanced by depositing a molten mass of fiber material and protruding staple fiber filament ends on a striking projectile upon impact on outer layers, and transporting the additional mass into the panel with a higher coefficient of friction.

In one particular embodiment, the disclosure is directed to a conveyor belt including a set of warp knitted yams (106) configured in warp-oriented wales and a set of weft insert yams (102) inserted in the set of warp-oriented wales. The set of weft insert yarns have a cross-sectional aspect ratio at least about 2:1.

The inventive woven cloth (1) is based on high-strength yarns, in particular fibreglass yarns, is used for reinforcing parts moulded by resin transfer moulding (RTM) and comprises threads (3) which are disposed in a weft direction and are not perpendicular to a warp threads (2). Said woven cloth is characterised in that a ratio Tc?Dc/ Tt?Dt ranges from 0.2 to 0.8, wherein Tc is a warp thread number (2), Tt is weft tread number (3), Dc is the number of warp threads (2) per length unit,?Dt is the number of weft threads per length unit.

A composite construction comprising a mat structure comprising a plurality of layers, each layer comprising plurality of fibers, a multiplicity of embedded fiber elements extending in anchored relation at least partially across the thickness dimension of the mat structure such that at least a portion of the embedded fiber elements project outwardly from the mat structure and the projecting portions define at least a partial surface covering across a first side of the mat structure, and a substrate layer disposed in layered relation to the mat structure in contacting, bonding relation with said first side of the mat structure such that at least a percentage of said portion of embedded fiber elements projecting outwardly from the mat structure is at least partially bonded or embedded into a surface portion of the substrate layer. The composite is adapted for bonding to a substrate layer.

Disclosed herein is a fabric to be used for restraint devices having both internal pressure-holding capability or low air permeability and mountability or wearer comfort, especially for air belts suitable for practical use. The fabric to be used for restraint devices includes a coated woven fabric obtained by coating, with a resin, at least one surface of a woven fabric containing multifilaments, each of which is composed of microfibers each having a fineness of 0.05 to 1 dtex, wherein the thickness of the coated woven fabric is in the range of 0.10 to 0.25 mm.
摘要:
A polyester fabric having a total cover factor of not lower than 1500 and a mass per unit area of not higher than 45 g/m 2 , wherein said polyester fabric is composed of polyester multifilament A yarns having a total fineness of not higher than 25 dtex (decitex) and a single yarn fineness of not higher than 2.0 dtex and multifilament B yarns having a total fineness of not lower than 35 dtex, wherein the arrangements of the respective yarns in the warp and weft directions are such that the yarn constitution ratio "B yarn/A yarn" is 1/4 to 1/20 (number of yarns-to-number of yarns ratio) and wherein the A yarn-to-B yarn pitches are not longer than 7 mm. The polyester fabric is light in weight, high in density and flexible by using extra-fine polyester multifilaments finer as compared with the conventional polyester multifilaments and, at the same time, has a sufficient level of tear strength.
