At the same time, the hot shrinkage, crimp ratio and crimprigidity increase with the increasing heat treatment temperature and time.
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。

It is shown that the shrinkage, crimp ratio of CDP-FDY fibers reduce and the crimprigidity increase with the increasing drawn temperature.
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；

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 crimprigidity.
