Polyethylene terephthalate-based hook-and-loop fastener and method for manufacturing same

A polyethylene terephthalate-based woven hook-and-loop fastener, which comprises, 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, wherein 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 polyester-based heat-fusible multifilament yarn, wherein a melting peak temperature of the warp yarn by DSC measurement is in a range of 251.0 to 257.5° C., and

• wherein a molecular weight distribution (Mw/Mn) of the polyethylene terephthalate constituting the warp yarn is in a range of 4.0 to 4.5.
