Abstract

See full text

A method for making a sheet material adapted to be cut into smaller ravel resistant pieces to form portions of a fastener by intersecting (e.g., weaving or knitting) portions of base yarns to form a backing, with at least some of the base yarns being bonded yarns including a first portion formed of a polymeric structural material and a second portion formed of a thermoplastic binding material having a significantly lower melting temperature than the softening temperature of the structural material. Portions of pile yarns are entwined in the backing with the entwined portions of the pile yarns contacting at least one of the bonding yarns, while other portions of the pile yarn project from the backing to form loops or hooks. The backing is heated to soften the binding material so that it flows and, upon cooling, adheres to adjacent portions of the yarns, thereby anchoring the pile yarns in the backing.
