overflow-wrap: break-word !important;">氨纶纤维（简称PU纤维），属于聚氨酯类结构，具有高延伸性、低弹性模量和高弹性回复率，此外，氨纶还具有优良的化学稳定性和热稳定性，它比乳胶丝更耐化学降解，软化温度约在200℃以上。氨纶纤维耐汗、耐海水并耐各种干洗剂和大多数防晒油。长期暴露在日光下或在氯漂白剂中也会退色，但退色程度随氨纶的类型而不同，差异很大。用含氨纶织物制作的服装保型性好，尺寸稳定，无压迫感，穿着舒适。通常只要加入2%～10%的氨纶，即可使内衣柔软贴身、舒适美观，使运动装合体柔软、活动自如，使时装和休闲装具有良好的悬垂性、保型性和时尚性。因此，氨纶是发展高弹性纺织品必不可少的纤维。 </span></p></section><section style="margin: 0px 8px;
