利用传统设备生产低强高伸聚丙烯短纤维

USING TRADITIONAL EQUIPMENT TO PRODUCE LOW TENACITY HIGH ELONGATION POLYPROPYLENE STAPLE

利用传统设备生产非织造布用低强高伸聚丙烯短纤维，探讨了影响其强度、熔点、断裂伸长率的主要因素，并提出合理选择聚丙烯原料、添加剂及纺丝拉伸的工艺条件，是生产低强高伸抗静电聚丙烯短纤维的关键。

The production of low tenacity high elongation polypropylene staple convenient to non woven fabric using traditional equipment was studied. The main factors effective for tenacity, melting point and elongation at break were analyzed. It was suggested that the production of the title staple with excellent antistatic property required the reasonable selection of the raw material, additives and spin drawing conditions.
