Abstract:
1. A hook surface fastener comprising: a base fabric; and hook engaging elements formed on the base fabric, wherein: the base fabric is a woven fabric comprising warp yarns, weft yarns and fibers constituting the hook engaging elements, and the warp yarns and the fibers constituting the hook engaging elements are polyphenylene sulfide fibers; the polyphenylene sulfide fibers constituting the hook engaging elements have a crystal orientation of 85.0 to 90.0% and a crystallinity of 32.0 to 42.0%; the weft yarns are substantially non-twisted, paralleled yarns comprising polyphenylene sulfide fibers and heat-fusible fibers having a melting point or a softening point each being 230° C. or lower; a ratio of the heat-fusible fibers to the fibers constituting the base fabric is 10 to 25% by weight wherein the fibers constituting the base fabric are total of the warp yarns and the weft yarns exclusive of the fibers constituting the hook engaging elements, and the fibers constituting the hook engaging elements are anchored to the base fabric by fusion of the heat-fusible fibers; substantially no resin coat layer is provided on a back surface of the base fabric; the polyphenylene sulfide fibers constituting the hook engaging elements are monofilaments of 200 to 600 dtex; and the fibers constituting the hook engaging elements are included in the base fabric as a part of the warp yarns.
