Woven fabric surface fastener having hook-shaped engaging element, and method for manufacturing same

Abstract

A woven-fabric hook-and-loop fastener including: a woven base fabric made of a woven-fabric made of a warp yarn and a weft yarn; a yarn for hook-shaped engaging elements made of a polyethylene terephthalate-based monofilament yarn woven into the woven base fabric in parallel with the warp yarn; and a plurality of the hook-shaped engaging elements formed from the yarn for the hook-shaped engaging elements and rising from a front face of the woven base fabric, on a front face side of the woven base fabric, in which a height of the hook-shaped engaging elements satisfies condition (1) described below and a hook shape of the hook-shaped engaging elements satisfies condition (2) described below: (1) 90% or more of the hook-shaped engaging elements present on the face of the base fabric have a height in a range of 0.975 to 1.025 times an average height (Ha) of the hook-shaped engaging elements; and (2) 90% or more of the hook-shaped engaging elements present on the face of the base fabric have a lateral-direction spread (W) of the hook-shaped engaging elements within a range of 0.7 to 0.8 times with respect to the height (H) of the hook-shaped engaging elements.
