Abstract

A cord comprises a braided sheath of strands having an outer surface, an inner surface, and a central hollow portion defined by the inner surface and having a volume and a core within the central hollow portion of the tubular braided sheath, such that when the cord is in a relaxed state the tubular braided sheath has a cylindrical shape and a relaxed volume of the central hollow portion wherein the core does not fill the relaxed volume of the central hollow portion of the tubular braided sheath; when the cord is in a longitudinal tensioned state, the tubular braided sheath elongates under the longitudinal tension such that a tensioned volume of at least a part of the central hollow portion of the tubular braided sheath is less than the relaxed volume; and the inner surface of the tubular braided sheath of tensioned volume contacts and cinches a surface of the core.

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.
