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。
The results show that, after soaking by acid rain, dry heat shrinkage ratio of the leather increases, and the dry thermostability decreases.
结果表明：经过酸雨浸泡后，加脂皮革的干热收缩率均高于未浸泡试样，耐干热性能下降。
