提高丙纶BCF卷曲性能的工艺探讨

DISCUSSION ON IMPROVING THE CRIMPING PROPERTY OF PP-BCF YARN

通过改善聚丙烯熔体的流变性能、调整拉伸和变形工艺、控制卷绕张力和油剂加入量,可有效地提高丙纶BCF的卷曲性能.

By improving PP melt rheological properties, adjusting draw-texturing process, controlling winding tension and oil content, the crimping property of PP- BCF yarn can be improved effectively.
