1. A polyester woven-fabric hook-and-loop fastener, comprising:
a woven base fabric formed of a warp yarn and a weft yarn, and
a yarn for engaging elements, woven in parallel to the warp yarn of the base fabric,
the yarn for engaging elements forming a number of loop-shaped engaging elements, hook-shaped engaging elements, or both that rise up from a front surface of the base fabric,
each of the warp yarn, the weft yarn, and the yarn for engaging elements being of a polyester fiber,
the weft yarn containing a heat-fusible fiber,
the engaging elements each being fused at a root thereof to the heat-fusible fiber to thus be fixed to the base fabric, and
the polyester woven-fabric hook-and-loop fastener satisfying requirements (1) and (2) described below:
(1) the warp yarn alternately runs over and under the weft yarn with the weft yarn interposed therebetween, and a thickness Tb thereof in a base fabric thickness direction at a point where the warp yarn is the most subducted toward a base fabric rear surface side is 0.94 times or less a thickness Ts thereof in the base fabric thickness direction at a point where the warp yarn is the most floated toward a base fabric front surface side, and
(2) a selvage area having no engaging elements is present continuously in a warp direction on each of two opposite ends parallel to the warp yarn on the base fabric front surface side.
