聚丙烯烟用丝束仿真生产技术

THE ARTIFICIAL TECHNOLOGY OF PP TOW FOR CIGARETTES

研究用改进后的HP— 0 2 1型短程纺丝设备生产烟用改性丝束的主要生产工艺技术。经采用多孔异形喷丝板纺丝 ,二步法油浴拉伸 ,改进的卷曲工艺 ,最后进行特殊的后加工处理 ,制得的烟用改性丝束使用性能接近于二醋酸纤维 ,完全能替代中档烟嘴及部分高档烟嘴的原料需求。

This article introduces the main process technology of production of PP modified tow for cigarettes by improved HP-021 type short-range spinning machine.It proved that PP modified tow for cigarettes has properties similar to acetate fibre and can be used in middle-grade or some high-grade filter bars of cigarettes.
