  • Patent number: 6716778
    Abstract: The invention discloses a textile laminate (1, 400, 450) with a first layer (5) comprising a waterproof and preferably breathable functional layer (10, 20) and a second layer (30) comprising at least a first component and a second component. The first component is stable to a first temperature and the second component melts at a lower second temperature. In one embodiment of the invention, the first component is polyester and the second component may be a thermoplastic such as copolyester, polyamide, copolyamide or polyethylene. The textile laminate (1) is particularly advantageous when two of such laminates (1, 400, 450) have to be joined or fused together. In this case a waterproof seam is created at the seam (500) between the two laminates (1, 400, 500).

    Abstract: A thermoplastic spatial fabric application includes at least two chemical fibers having different melting points. The chemical fibers are processed by a weaving technology, so that the chemical fibers may be intersected and formed, thereby forming a spatial fabric having multiple layers. In addition, the spatial fabric may be treated by a heating process, so that the chemical fiber having a lower melting point may be melted to form a layer having a greater strength and stiffness, and the chemical fiber having a higher melting point may maintain the original features to form a layer having an excellent softness, permeability and elasticity, thereby forming a spatial fabric product with predetermined physical features. Accordingly, the physical features (such as the stiffness, elasticity, softness or the like) of the spatial fabric may be designed previously so as to satisfy the practical requirements.

  • Patent number: 6187436
    Abstract: A water-retentive sheath manufactured from a cellulose based fiber of high water-retentivity. The cellulose based fiber of high water rententivity includes a component of a non-cellulose based material of high absorbency uniformly contained in a cellulose fiber and a single component of cellulose; and these two components are attached together side by side. The cellulose fiber can be viscose rayon and the non-cellulose based material of high absorbency can be polyacrylate salt.

  • Patent number: 6069204
    Abstract: The present invention is directed to a monofilament made from a blend of a polyester having a polyhydric alcohol of 1,4-cyclohexane-dimethanol, a polyamide, and a polyolefin. This blend is useful as an article of paper making machine clothing when the blend is in the form of a fiber structure. Particularly, this blend is useful in spiral fabrics having good dry-heat strength and hydrolysis resistance.

  • Patent number: 6020275
    Abstract: Bonded composite open mesh structural textiles are formed of woven textile. The textile is formed from at least two, and preferably three, components. The first component, or load bearing member, is a high tenacity, high modulus, low elongation mono- or multifilament yarn. The second component is a polymer in yarn or other form which will encapsulate and bond yarns at the junctions to strengthen the junctions. The third component is an optional effect or bulking yarn. In the woven textile, a plurality of warp yarns are woven with a plurality of weft (fill) yarns. The weave preferably includes a half-cross or full-cross leno weave. At least a portion of the warp and weft yarns are first component load bearing yarns. The polymer component is used as required for the bonding properties necessary for the finished product, and especially to provide improved junction or joint strength.

  • Patent number: 6007911
    Abstract: Industrial fabrics which contain thermoplastic weft or filling filaments characterized by having at least one segment of the filament's cross sectional area consisting of a foamed polymer are described. The unfoamed segment or segments of the filament contribute axial strength while the foamed segment or segments of the filament contribute to radial compressibility. Industrial fabrics utilizing these filaments have reduced permeability, reduced weft denier, and improved fabric rigidity.

  • Patent number: 6008146
    Abstract: An improved composite material of high temperature and chemical resistant material and polytetrafluoroethylene (PTFE) is provided. The composite material incorporates a coherent strand of commingled filaments of fiberglass and PTFE which is far more resistant to flex, abrasion, and chemical attack than conventional materials. Preferably filaments of expanded PTFE tow yarn and filaments of PTFE are combined through a process of air-jet texturing. Fabrics made from the composite fibers are combined with thermosetting phenolic or epoxy resins to produce pleated cartridge filter elements exhibiting superior performance in high temperature and corrosive environments.

  • Patent number: 5985999
    Abstract: This invention concerns a composition comprising a blend of polyolefin with the reaction of a functionalized polyolefin and polyetheramine in which the polyetheramine is grafted into the functionalized polyolefin in a customary mixing apparatus. A process for producing the reaction product of functionalized polypropylene and polyetheramine by melting with polypropylene in a customary mixing apparatus is also disclosed. Blends of the present invention are advantageously useful to prepare paintable automotive body parts. This invention further includes dyeable polyolefin compositions containing the reaction product of functionalized polyolefin and polyetheramine. Dyeable polyolefin fibers, including polypropylene fibers, are disclosed, which may be made by melt spinning, and which may be employed to make woven and non-woven fabric.
