Abstract
An elongate webbing has opposed longitudinal edges formed from warp and fill yarns interwoven together, and a catch cord for interconnecting the fill yarns adjacent one of the longitudinal edges. The catch cord is fabricated from a yarn having a component with a melting point lower than the warp and fill yarns for bonding of the catch cord with the warp and fill yarns when being subjected to a melting temperature sufficient to melt the catch cord but not the warp and fill yarns. More specifically, the catch cord is fabricated from a bicomponent yarn having a plurality of individual filaments, each filament having a core and an outer sheath. The melting point of the sheath of each filament is lower than that of its core. The core of each filament is preferably fabricated from polyester having a melting point at about 489.degree. F., and the sheath of each filament is fabricated from a group consisting of nylon-6, polypropylene, or polyethylene, or any other material having a lower melting point than the melting point of the core.
