  • Patent number: 10590570
    Abstract: A woven fabric that is advantageously used for sportswear, and has a high tear strength, maintains a low air-permeability, and has a good abrasion resistance while the fabric is lightweight and thin. The woven fabric comprises a synthetic multifilament comprising a modified monofilament having a filament transverse cross-section of a substantially quadrilateral shape, wherein: the synthetic multifilament has a total fineness 5 to 60 dtex; the modified monofilament has a single yarn fineness of 1.0 to 7.5 dtex; the woven fabric includes the synthetic multifilament in an amount of 45% or more by mass relative to 100% by mass of the woven fabric; and an average contact length where the modified monofilament touches a modified monofilament adjacent thereto is 8 to 40 ?m on a cross-section in a direction perpendicular to the synthetic multifilament.

  • Patent number: 10323341
    Abstract: An object of the present invention is to provide a highly air-permeable woven fabric whose air permeability does not easily deteriorate even after repetitive washing and which has a good fabric quality. The woven fabric of the present invention comprises warp threads constituted by substantially quadrilateral shaped filaments and weft threads constituted by substantially quadrilateral shaped filaments. The warp threads and the weft threads overlap each other in an alternating manner forming crossover points comprising front threads and back threads, such that the warp threads and the weft threads alternate constituting the front threads. The crossover points comprise first crossover points and second crossover points. The first crossover points are the crossover points where the substantially quadrilateral shaped filaments constituting the front threads are aligned in a line.

  • Patent number: 9783916
    Abstract: Provided is a woven fabric which is suitable for use as a covering fabric for down garments, down jackets, bedclothes, sleeping bags, etc. The woven fabric is lightweight and thin, has a high tear strength, and can retain low air permeability even after laundering. The woven fabric is constituted of synthetic multifilament yarns. The woven fabric is characterized in that at least one side thereof has been calendered and the monofilaments in at least part of the synthetic multifilament yarns have been thereby compressed in a stacked state. The woven fabric is further characterized in that the monofilaments are fibers having an unusual cross-section, the degree of unusualness of the cross section as determined before calendering being 2.0-6.0, that the synthetic multifilament yarns have a fineness of 7-44 dtex, and that the woven fabric has a cover factor of 1,300-2,200.

  • Patent number: 9670605
    Abstract: Provided is a fabric that is favorably used for a side cloth of a down wear, a down jacket, a futon, a sleeping bag or some other, and that is light, thin and high in tear strength and can further keep a low air permeability after washed. The high-density fabric of the present invention that can attain the purpose is a fabric including a synthetic fiber that has a fineness of 28 dtex or less, and having a total cover factor ranging from 1700 to 2200. In this fabric, multifilaments are present in each of which monofilaments are arranged in the form of two layers in at least one direction of warp and weft directions. Furthermore, the fabric has a cover factor ranging from 700 to 900 in at least one direction of the warp and weft directions which has the multifilaments present.

  • Publication number: 20110195229
    Abstract: The invention provides a moisture-permeable waterproof fabric which not only has a tear strength at a practical level but also is light, thin, soft in texture and excellent in moisture permeability and waterproofness. The moisture-permeable waterproof fabric is a fabric in which two urethane resin layers are coated at least on one surface of a woven fabric, wherein a first urethane resin layer is a porous urethane resin layer which is discontinuously coated on the surface of the woven fabric to fill recesses of a weave crimp but not to cover at least a part of projections of the weave crimp; and a second urethane resin layer is a hydrophilic urethane resin layer which is continuously coated on the first urethane resin layer and the projections of the weave crimp.
