分子式:
CAS号:

性质:指纤维轴向有细管状空腔的化纤。按其作用分两类:①絮片用,中空度要求不高,约30%~100%,主要追求轻而保暖,为了提高其回弹率,还可制成偏芯中空纤维,经热处理而形成三维卷曲;②分离膜用,中空度和截面圆整度要求高,膜壁微孔及其分布有一定要求,还可涂一层或两层不同超薄分离层,以提高分离效果和选择性。制法有(1)采用环形中空、C形或偏心中空喷丝板通过熔纺(涤纶等)或溶液纺成纤;(2)用中空型(个别用C形)喷丝板,通过干湿纺或熔纺成纤,有些中心部还需通入空气或不同组成的凝固液,制成系列产品。可用于冬装、被褥和衬垫用絮片等;组装成微滤、超滤、透析、气体分离、反渗透及蒸发渗透器等。
