摘要： A polyethylene terephthalate-based woven hook-and-loop fastener which contains, as a woven base fabric, a fabric having a multifilament yarn made of polyethylene terephthalate as a warp yarn and a polyester-based heat-fusible multifilament yarn as a weft yarn, in which a monofilament yarn made of polyethylene terephthalate is woven in parallel with the warp yarn into the woven base fabric, a hook-shaped engaging element formed from the monofilament yarn and rising from the surface of the woven base fabric exists on the surface of the woven base fabric, and a root of the hook-shaped engaging element is fixed to the woven base fabric by a melt-solidified product of a heat-fusible component of the heat-fusible multifilament yarn, in which a melting peak temperature of the warp yarn by DSC measurement is in a range of 251.0 to 257.5° C.

摘要： A conductive hook-and-loop fastener that has a high engagement force, undergoes less decrease in conductivity even after repeated engagement and release, and is significantly flexible. The conductive hook-and-loop fastener includes a base cloth containing a woven fabric, having existing on one surface thereof plural loop engagement elements including a multifilament yarn including as at least a part thereof a conductive filament, and the multifilament yarn constituting the loop engagement elements is inwoven in a warp direction of the woven fabric.

摘要： A polyester woven-fabric hook-and-loop fastener has a warp yarn thickness Tb which is 0.94 times or less of a warp yarn thickness Ts. A selvage area having a constant width is present on two opposite ends, continuously in a line form in the warp direction, without misalignment in the weft direction. As a result, when the polyester woven-fabric hook-and-loop fastener is sewn onto a garment or the like, a sewing thread sewn to the selvage area is in a straight line without meandering, and thus a sewn product excellent in appearance can be obtained.
