This invention relates to a process for forming composite yarns comprising an elastic filament and at least one relatively inelastic filament, which process comprises entangling a latent-contractable elastomer producing polymer filament with a relatively inelastic filament while the latent-contractable filament is relatively unelongated (less than tension maintained 100% elongation) or preferably substantially unelongated (merely taut) to produce a composite yarn which can be formed into a yarn package with minimum stored energy compared to conventional elastomeric yarn packages and which yarn can be processed (e.g., knitted or woven) into goods on equipment normally employed for non-elastic fiber processing; and yet which composite yarn upon actuation of the latent contraction within the polymeric filament provides a composite yarn which is elastic.
