摘要
通过沸水收缩率、干热收缩率、卷曲度、卷曲弹性率等一系列测试方法讨论了不同拉伸温度的CDP -FDY纤维热处理后的收缩和卷曲性能。结果表明 :拉伸温度高的CDP纤维的收缩率、卷曲度低 ,而卷曲弹性率高 ;CDP -FDY纤维的干热收缩率、卷曲度、卷曲弹性率均随热处理温度的上升、时间的延长而提高。
The shrinkage and crimp behavior of CDP-FDY fibers at different drawn temperature after heat treatment are studied by means of boiling water shrinkage, hot shrinkage, crimp ratio and crimp rigidity. It is shown that the shrinkage, crimp ratio of CDP-FDY fibers reduce and the crimp rigidity increase with the increasing drawn temperature. At the same time, the hot shrinkage, crimp ratio and crimp rigidity increase with the increasing heat treatment temperature and time.
