ABSTRACT OF THE DISCLOSURE This invention relates to a latent contractable melt extruded segmented, inherently elastic, physically cross-linked polyester-polyester or polyester-polyether thermoplastic polymer filament characterized by containing interspersed relatively hard segments and relatively soft segments, which contracts at least 15% in length when sub- jected to an elevated temperature, as compared to the length of the melt extruded filament prior to contraction to yield an elastic filament. In addition, this invention relates to processes for forming covered yarns from the above filaments. Yet further, this invention relates to processes for forming articles from the latent contractable filaments, which can be processed in a non-stretched mode, as a conventional yarn, and when processed into an article, can be contracted to pro- vide an elastic article.
