烟滤嘴用聚丙烯膜裂纤维的研制 第Ⅰ报 原料对聚丙烯膜裂纤维的制造及其结构和性能的影响

THE DEVELOPMENT OF POLYPROPYLENE SPLIT FIBRE FOR CIGARETTE TIPS Pt.Ⅰ. The Influence of Raw Materials on the Production, Structure and Property of PP Split Fibrs

本文讨论了不同熔流指数PP及改性剂对股裂纤维制备的影响,认为制备膜裂纤维用的PP熔流指数应低于5,且在原料中混入一定量TiO_2和LDPE对制备膜裂纤维更有利。

The influences of PP chips having different melt indices and the modify agents on manufacture of PP split fibre are discussed.It is shown that the MI of PP chips used should be less than 5 and blending a certain amount of Tio2 and LDPE with PP is of great advantage in the production of PP split fibre.
