Abstract
A water-soluble male-type molded hook-and-loop fastener includes a substrate and a plurality of male-type engaging elements, arranged in rows, protruding from the substrate surface. The engaging elements have a shape rising from the substrate surface and curving mid-course in a row direction, or a shape rising from the substrate surface, branching forward and backward mid-course in the row direction and curving in the row direction, with tip portions oriented toward the substrate surface in either shape. The substrate and the engaging elements both contain a mixture of a polyvinyl alcohol, 5 to 30 parts by mass of a polyhydric alcohol- or ethylene oxide-based polymer, and 3 to 20 parts by mass of a layered inorganic particle, based on 100 parts by mass of the polyvinyl alcohol. The polyvinyl alcohol has a degree of polymerization of 300 to 700 and a degree of saponification of 60 to 80% by mole.
