    Abstract: A multilayer woven industrial fabric comprises at least two layers of weft yarns interwoven with at least one system of warp yarns. At least some of the machine side (MS) weft yarns are arranged as complementary pairs, such that for each pair, the members follow mutually complementary paths, and exchange positions with each other so that, in the MS surface, the path of a pair of weft yarns appears to be that of a single yarn. The complementary weft yarns interweave only with the MS warp yarns and do not appear in the paper side. The unique MS weft yarn arrangement allows for the use of smaller yarns, while increasing fabric stiffness and dimensional stability, and is applicable to any multi-layer fabric design which includes at least two layers of weft yarns and one system of warp yarns.

  • Patent number: 8129294
    Abstract: Novel woven materials, producible by a new weaving method, are described that comprise single or doubled warps and wefts in the form of tapes that are preferably partially stabilized type of fibrous tape. These fibres are caused to occur in a non-linear arrangement during the weaving process. The non-linear fibres can be subsequently straightened by pulling the tape longitudinally. The doubled warps and wefts comprise disconnected tapes. Such separateness of constituent tapes of doubled warp and weft tapes enables them to be slid/slipped relative to each other by pulling longitudinally and laterally without causing any alteration in the woven structure. These novel fabrics solve the problem of uneven fibre distribution and orientation arising from crumples/wrinkles due to compression and stretches due to extension, at the inner and outer sides respectively, when tape-woven fabrics are curved into shapes.

  • Publication number: 20110097959
    Abstract: Disclosed are water-dispersible fibers derived from sulfopolyesters having a Tg of at least 25° C. The fibers may contain a single sulfopolyester or a blend of a sulfopolyester with a water-dispersible or water-nondispersible polymer. Also disclosed are multicomponent fibers comprising a water dispersible sulfopolyester having a Tg of at least 57° C. and a water non-dispersible polymer. The multicomponent fibers may be used to produce microdenier fibers. Fibrous articles may be produced from the water-dispersible fibers, multicomponent fibers, and microdenier fibers. The fibrous articles include water-dispersible and microdenier nonwoven webs, fabrics, and multilayered articles such as wipes, gauze, tissue, diapers, panty liners, sanitary napkins, bandages, and surgical dressings. Also disclosed is a process for water-dispersible fibers, nonwoven fabrics, and microdenier webs.

  • Publication number: 20110092123
    Abstract: Disclosed are multicomponent fibers derived from a blend of a sulfopolyester with a water non-dispersible polymer wherein the as-spun denier is less than about 6 and wherein the water dispersible sulfopolyester exhibits a melt viscosity of less than 12,000 poise measured at 240° C. at a strain rate of 1 rad/sec, and wherein the sulfopolyester comprising less than about 25 mole % of residues of at least one sulfomonomer, based on the total moles of diacid or diol residues. The multicomponent fiber is capable of being drawn at a relatively high fiber speed, particularly at least about 2000 m/min, and may be used to produce microdenier fibers. Fibrous articles may be produced from the multicomponent fibers and microdenier fibers. Also disclosed is a process for multicomponent fibers, nonwoven fabrics, and microdenier webs.

  • Patent number: 7892990
    Abstract: A press pad is provided for use in a laminate press. The pad includes a woven fabric of heat resistant strands wherein at least either the warp or the weft has a core made up of a plurality of strands within a sheath of an elastomeric material, and the other is made up of metal strands. Within the scale of the press pad, the strands making up the core lie substantially parallel to one another and to the longitudinal axis of the core. In use, therefore, when pressurized in the laminate press, the core structure collapses as the strands making up the core move relative to one another and the core tends to flatten out. This increases the springiness and compensation ability of the press pad without any loss of heat transfer ability.

  • Patent number: 7820945
    Abstract: Disclosed is a heating fabric comprising a heating fabric element made by weaving woof fibers and warp fibers, a pair of conductive parts being a plain fabric made by a weaving method to extend from one side edge of the heating fabric element, for supplying electric power to the heating fabric element, wherein electrode fibers are woven in rows as warp threads in the conductive parts and a heating fiber is intermittently woven as woof threads at predetermined intervals so as to be conductive with the conductive parts, and wherein the heating fiber is woven in a zigzag pattern on the other side of the plain fabric of the conductive parts, in which one end of the heating fiber is woven into the conductive part, and a portion of the other end of the heating fiber is not woven into the conductive part, thereby forming a jumping portion having a length longer than a width of the conductive part, the jumping portion jumping over the conductive part so as not to be conductive with the conductive part.
