摘要： The present invention provides melt processable, bleach resistant durable fibers having an elastic recovery above 50% after extension to 160% elongation and a stress relaxation below 50% after extension to 150% for 30 minuets which are formed from a soft polyurethane elastomer. This elastomer is comprised of (a) from 75 to 90% weight of a polydiene diol having up to about two terminal hydroxyl groups per molecule and a number average molecular weight between 500 and 20,000, (b) from 9 to 25% weight of a diisocyanate, and (c) from 0.8% to 5% weight of a chain extender which is a low molecular weight aliphatic diol, or a mixture of the low molecular weight aliphatic diol and from 0.1 to 4.0 mol % of a diamine wherein the hard segment content of the polyurethane elastomer is from about 10 to about 30% weight. The present invention further provides a polyurethane elastomer.
