摘　　要：本实验旨在优化聚乙烯纤维生产工艺,提高纤维性能,将聚乙烯熔融纺丝进行萃取干燥和牵伸,用二甲苯作为萃取剂对不同石蜡含量聚乙烯原丝进行萃取实验,对萃取后的原丝进行热牵伸,得出高温下萃取效果高于低温,且石蜡含量越高萃取效果越好,但牵伸难度越大。从而提高了产品质量和生产效率。The purpose of this study is to optimize the production process of polyethylene fiber and improve the performance of the fiber.Using Polyethylene melt spinning to extraction dry and drawing,with xylene as the extractant for different wax content＇s polyethylene strands to extraction experiments,after extraction of raw silk hot drawing, extraction efficiency obtained at a temperature higher than a low temperature and higher wax content extraction effect is good, but the difficulty of drawing more. So improve the quality of products and production efficiency.
