Abstract:
The present invention provides protective goods, for example arctic clothing which allows long-time working even under the low temperature environment; said protective goods being characterized by excellent workability, heat-insulation and anti-static feature, without being hardened and embrittled, especially at the temperature of -10 degrees Celsius or below, further, under the environment of very low temperature such levels as -30 degrees Celsius or -60 degrees Celsius, furthermore even under the environment of extremely-low temperature on the level of -100 to -250 degrees Celsius. Protective goods made from a multiple-layer composite cloth, characterized in that said composite cloth comprises a surface fabric, an intermediate fibrous-insulator and a lining fabric, mainly composed of aramid fiber, respectively, wherein 1) said surface fabric and said lining fabric, comprises meta-aramid fiber by weight of 50 to 100 percent, para-aramid fiber by weight of 0 to 10 percent and other flame-retardant fiber by weight of 0 to 40 percent, with provision that total weight-percent of meta-aramid fiber, para-aramid fiber and other flame-retardant fiber, is 100; 2) said intermediate fibrous-insulator comprises a multiple-laminated felt made from aramid fiber; and 3) electro-conductive yarns (a) are arranged along lengthwise direction of said surface fabric at a density of 1 to 5 per inch and additional electro-conductive yarns and/or tapes (b) are arranged along the direction intersecting said lengthwise direction to form contact points with said electro-conductive yarns (a), whereby triboelectric charge on the outside surface of said protective goods is less than 0.6 micro-coulomb/m2.
Abstract:
A composite fabric having inner and outer layers and a middle layer therebetween. The inner and outer layers may be the same or different and each layer is made up of a plurality of sub-layers. The individual sub-layers are resin bonded substantially unidirectional anti-ballistic non-woven fibers. The same or a different number of sub-layers may be used as the inner and outer layers, respectively. The middle layer is made up of a plurality of woven fabric sub-layers. Each sub-layer is a woven fabric, comprising anti-ballistic fibers or yarns, which has been calendared to an extent sufficient to flatten the sub-layer fabric and to spread the fibers of the woven yarns into the void spaces created by the weaving.
Abstract:
Composite materials having favorable acoustic and vibration damping properties, while maintaining or improving other composite mechanical properties, include an interleaf layer comprising at least two different nonwoven materials in a specific sequence such that a gradient is formed in the z direction upon curing or an interleaf with a compositional gradient within its structure such that a resin interpenetration gradient is achieved upon curing. Composite materials that contain multilayered nonwoven interleaves are useful, for example, in structures found in aircrafts, such as fuselage skins, stringers and frames. Also contemplated are methods of making the composite material and the structures and aircrafts that contain the composite material.
Abstract:
A roofing underlayment comprising a top layer, a bottom layer and a water-sealing composition layer positioned between the top layer and the bottom layer wherein the water-sealing composition consists essentially of at least 80 weight percent of a copolymer of ethylene and at least one comonomer selected from the group consisting of alkyl acrylate, alkyl methacrylate and vinyl acetate is disclosed. The top and bottom layers independently comprise a fabric selected from the group consisting of nonwoven polypropylene, nonwoven polyethylene, nonwoven polyethylene terephthalate, woven polypropylene, woven polyethylene, spunbond polypropylene, and spunbond polyester. The roofing underlayment may optionally comprise additional layers.
Abstract:
The present invention contemplates a method of forming a textile laminate or composite fabric from a plurality of woven fabric layers, with the method contemplating use of a three-dimensional image transfer device to facilitate efficient and commercially viable use of the method. Herein is disclosed a method of forming an imaged textile laminate or composite compound fabric, the fabric having a first textile fabric layer (11) comprising a plurality of interwoven warp and weft yarns and at least one other textile fabric layer (10), the lamination of the fabric layers and imaging of the construct occurring on a three-dimensional image transfer device (18). The image transfer device (18) has a foraminous, image-forming surface comprising a regular pattern of three-dimensional surface elements.
