异形截面EDDP纺丝工艺研究

Study on spinning technology of profiled EDDP

采用3种异形喷丝板在两部位实验机上对EDDP切片进行POY纺丝实验,通过对干燥、纺丝、卷绕等关键工艺的控制,优化异形截面EDDP纺丝工艺。

A spinning experiment on EDDP chip was carried out on the two spinning positions experiment machine in Ji'nan Zhenghao company using three kinds of profiled spinneret.Through the controlling of the key process of drying,spinning and winding etc,the spinning process of profiled EDDP was optimized.
