提高烟用聚丙烯丝束开松性能的工艺研究

A STUDY ON IMPROVING THE OPENABILITY OF PP TOWS FOR CIGARETTE FILTER TIPS

通过对烟用聚丙烯丝束生产线上纺丝、卷统、卷曲及定型等工艺的改进,可显著提高丝束的开松性能,从而解决后道成棒工序中存在的一系列问题。

The openability of PP tows for cigarette filter tips can be obviously improved by modifying the spinning, winding Crimping and heat setting process on the production line, thus a series problems existing in the tip forming process can be solved.
