crimp rigidity apparatus 卷曲刚性测定仪
At the same time, the hot shrinkage, crimp ratio and crimp rigidity 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 crimp rigidity 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 crimp rigidity.
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。
