Polyester-based woven hook-and-loop fastener and production method therefor

Abstract

A polyester-based woven hook-and-loop fastener including: a woven-fabric and engaging elements, in which the woven-fabric in which a polyethylene terephthalate-based multifilament yarn is a warp yarn and a polyester-based heat-fusible multifilament yarn is a weft yarn is a woven base fabric, a yarn for the engaging elements made of at least one kind selected from the group consisting of a polyethylene terephthalate-based monofilament yarn and a polyester-based multifilament yarn, is woven in parallel to the warp yarn into the woven base fabric, the engaging elements that are formed of the yarn for the engaging elements, that are made of at least one kind selected from the group consisting of a large number of hook shapes and loop shapes, and that rise up from a front face of the woven base fabric, exist on the front face of the woven base fabric, bases of the engaging elements are fixed to the woven base fabric by a melt-solidified material of a heat-fusible component of the polyester-based heat-fusible multifilament yarn, and the polyethylene terephthalate-based multifilament yarn is made of a copolymerized polyethylene terephthalate containing, as copolymerization components, 1.0 to 2.0 mol % of isophthalic acid with respect to a total amount of dicarboxylic acids and 2.0 to 3.5 mol % of diethylene glycol with respect to a total amount of diols.
