摘　　要：茂金属催化剂聚合得到的线性低密度聚(mLLDPE)纤维是近年来发展非常迅速的一种塑料品种,正在逐渐地取代传统聚乙烯产品。本文研究了熔体静电纺丝法制备线性低密度聚乙烯纤维,通过添加剂改性,首次成功制备了直径为10～80μm的mLLDPE纤维。对不同纺丝参数,包括纺丝电压、接收距离、纺丝温度及添加剂用量对mLLDPE纤维直径与形貌的影响进行了研究,得到熔体静电纺mLL-DPE的最佳条件为纺丝电压25kV、接收距离2cm、纺丝温度160℃、聚乙烯蜡添加量30%。对mLL-DPE纤维的结晶性能与纺丝温度及聚乙烯添加量之间的关系也进行了探讨。In recent years, metallocene based linear low-density polyethylene （mLLDPE） polymerized through metallo cene catalyst is a variety that has got rapid development and has gradually replaced traditional polyethylene products. In this paper, mLLDPE fibers prepared with melt electrospinning method was studied for the first time. The mLLDPE fibers, in a diameter from 10 to 80 t^m were successfully produced by an ~ddtion of polyethylene wax （PE wax）. The effects of various melt-electrospinning parameters including spinning voltage, collecting distance, spinning temperature and content of PE wax were studied. Got the optimum parameters, that is the spinning vohage of 25 kV, the collecting distance of 2 cm, the spin- ning temperature of 160 C, and the content of PE wax of 30%. The effects of electrospinning temperature and the content of polyethylene wax on the crystallization of mLLDPE fibers were measured.
