HIGHLY AIR-PERMEABLE WOVEN FABRIC RESISTANT TO WASHING

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. The second crossover points are the crossover points where at least 60% of the substantially quadrilateral shaped filaments constituting the front threads are aligned in a line. The rest of the substantially quadrilateral shaped filaments constituting the front threads overlap above and below in a thickness direction of the woven fabric, wherein, in a structure constituting five warp threads, six weft threads, and 30 crossover points, the total number of the first crossover points among thirty crossover points is not less than 10% and not more than 90%.

Woven fabric

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.
