什么是固體腈綸紗？固體腈綸紗的主要成分是什么

固體腈綸紗是(shi)(shi)重(zhong)要的(de)紡織面料，有(you)“合成羊毛(mao)”之(zhi)稱。彈性(xing)(xing)較(jiao)好(hao)，僅次于滌綸，比錦綸高約2倍，有(you)較(jiao)好(hao)的(de)保形性(xing)(xing)。 腈綸的(de)耐(nai)光性(xing)(xing)是(shi)(shi)所(suo)有(you)合成纖維中的(de)露天(tian)暴曬(shai)一年(nian)，強度(du)僅降(jiang)20％。 因(yin)為腈綸紗蓬(peng)松性(xing)(xing)好(hao)、手感柔軟(ruan)，常用(yong)(yong)來制作毛(mao)線、地毯等；因(yin)為有(you)良(liang)好(hao)的(de)耐(nai)氣候性(xing)(xing)和防霉(mei)、防蛀性(xing)(xing)能，還可(ke)以(yi)純紡或者(zhe)與天(tian)然纖維混紡，廣泛(fan)用(yong)(yong)于各種蓬(peng)布、裝飾、和產業領域、窗簾等行業；因(yin)為其保暖性(xing)(xing)好(hao)，也用(yong)(yong)來做服裝、長毛(mao)絨(rong)、人造毛(mao)皮等。
