Microporous polypropylene hollow fiber membranes were prepared by the melt spinning and cold stretching (MSCS) method.
采用熔融挤出拉伸法制备了聚丙烯中空纤维膜。

At first, we produced the polyethylene microporous hollow fiber membrane by ascending melting filature and made micropore by drawing.
首先，用向上熔融纺丝和拉伸致孔法制得聚乙烯中空纤维膜。
