POLYURETHANE UREA ELASTIC FIBER

摘要

Disclosed is a polyurethane urea elastic fiber containing 5-40% by weight of a polyurethane compound, wherein the compression deformation starting temperature determined by thermomechanical analysis (TMA) is not less than 150° C. but not more than 180° C. and time for thermal cutting at 180° C. is not less than 30 seconds.
