粗旦丙纶强力丝的生产初探

Study on the Production of Heavy Denier High Tenacity Polypropylene

介绍了粗旦丙纶强力丝的生产工艺、着色方法及存在的问题。认为聚丙烯切片的分子量、分子量分布以及纺丝、拉伸工艺的合理调整等是丙纶强力丝生产中的关键。

The production technology, the method of stain and the problems in the productio n are introduced. Some items such as molecule weight of PP chip, distribution of molecule weight and proper adjust to the techniques of drawing are the critical factors.
