Spandex fiber with copolymer soft segment
Abstract
A elastic fibers are formed from spandex polymer that is prepared by reacting a glycol prepared from a tetrahydrofuran/3-methyltetrahydrofuran copolymer with a diisocyanate and then chain extending the thusly capped glycol with a particular mixture of diamines. The fibers have a highly desirable combination of power, hot-wet creep and heat-set efficiency and can be prepared at high spinning and windup speeds.
