摘　　要：采用流延膜技术,通过纺丝涂覆装置在PET纤维表面进行PE涂覆改性处理,使新纤维形成特殊表面结构,获得持久的吸湿、导汗、速干功能。经实验验证,当涂覆层PE结晶度下降20%以上时,新材料透气率比PET提高3~5倍。新功能性材料价格比同类进口功能性纤维更具优势,具有一定的市场竞争力。Using casting film technology,PE is coated on the surface of PET fiber to modify it,and form a special fiber surface structure,so as to obtain long-lasting moisture absorption,perspiration conduction,and quick-drying functions.Experiment results indicated that when the crystallinity of PE decreased by more than 20%,the permeability of new modified fiber will 3-5 times stronger than the original one.Compared with imported moisture absorption and quick-drying fibers in the market,the modified spun yarn has obvious advantages in price and has certain market com petitiveness.
