  • 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.

  • 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.
