由基本上连续的熔纺纤维形成的无纺网幅是从具有偏斜分子量分 布和低于3.5的多分散性的聚丙烯均聚物形成的。
A nonwoven web formed of substantially continuous spunmelt fibers is formed from a homopolymer of polypropylene having a skewed molecular weight distribution and a polydispersity of less than 3.5.
高相对分子质量聚乙烯的增塑熔纺，由于聚合物浓度较高，大分子缠结多，纤维超拉伸比较困难，难以达到高强度。
Plasticized melt - spun HMWPE fiber is hard to draw to high strength because of high HMWPE content and more molecular tangle in as-spun fibers.
纺粘法纤维取向度比熔喷纤维高，纤维均匀。
Spunbonded fiber has more even fiber diameter and higher molecular orientation than that of melt blown fiber.
