  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 yarns comprising the latent contractable melt extruded filaments. In addition, this invention relates to processes for forming articles from the latent contractable filaments or covered yarns comprising the contractable filaments and subsequently contracting the yarns to form an elastic article.

  本发明涉及熔融挤出潜缩弹性长丝，这种长丝是通过熔融挤出某些分段交联热塑性聚合物形成的，当在高温下进行热处理时，这些长丝会明显收缩，从而产生弹性长丝。本发明还涉及复合包覆纱线的形成，该纱线由可潜伏收缩的熔融挤出长丝组成。此外，本发明还涉及用潜伏可收缩长丝或由可收缩长丝组成的包覆纱线形成物品的工艺，以及随后收缩纱线以形成弹性物品的工艺。
