MELT-SPUN ELASTOESTER MULTIFILAMENT YARNS.

摘要

This invention relates to a method of melt-spinning a polyether ester thermoplastic elastomer under commercially viable conditions to produce an elastoester multifilament yarn, wherein the polyether ester thermoplastic elastomer is a polytrimethylene ether ester comprising a polytrimethylene ether dicarboxylate ester soft segment and hard segment selected from a trimethylene dicarboxylate ester and/or a tetramethylene dicarboxylate ester hard segment.
