ABSTRACT:
This invention relates to melt extruded latent contractable elastic filaments which are formed by melt extruding certain segmented crosslinked thermoplastic polymers to form filaments, which filaments, when heat processed at elevated temperatures, significantly contract to yield an elastic filament. This invention also relates to the formation of composite covered yarn comprising said latent contractable melt extruded filaments. In addition, this invention relates to processes for forming articles from said latent contractable filaments or covered yarns comprising said contractable filaments and subsequently contracting said yarns to form an elastic article.
