摘要
介绍了干法腈纶的制条生产工艺。结果表明:干法腈纶因其纺丝成形工艺特殊,纤维结构致密,截面成犬骨状,因而与湿法腈纶有不同的特点。合理设定拉断热板温度及拉伸、各区域拉伸倍数、再割区隔距及梳理拉伸等工艺参数,可成功开发出符合需求的3.33dtex干法腈纶膨体毛条。
The technological development on hygroscopic and dry FDY is discussed. The special spinneret and Spin-draw process is designed, the factor of the influences to FDY profiled degree in the production process is analyzed. Result shocoes, hygroscopic and dry FDY produced at 4000-4500 m/min, run steadily, meet requirement of post processing, FDY profiled degree is up to 60 % , it is good material fohygroscopic and dry fabric.
