DISCOLORATION-RESISTANT SPANDEX

摘要

An improved fiber or film of a polyether-based spandex polymer composition provides increased heat set efficiency and greater discoloration resistance to the fiber or film. The polymer composition contains zinc oxide and a polyhydroxy additive selected from certain sugars, reduced sugars and/or polyhydroxy urethanes formed from these sugars or reduced sugars and an organic diisocyanate.
