卷曲率

探讨了生产涤纶短纤维过程中产生超长、倍长纤维，卷曲率波动和比电阻升高的原因。

The reasons , which result in over length fiber , double length fiber , crimp ratio waving and specific resistance rising , were discussed .

从卷曲率和死亡率来看：仍是乙醚提取液比丙酮、清水的高；

Deformed rate and mortality caused by treatment is higher than acetone and wate .

并讨论了棉纱捻系数和化纤卷曲率与成纱直径的关系。

In addition , the relationships are discussed between the twist factors of cotton yarn , the crimp ratios of chemical fibres and the yarn diameters .

测试结果比较得出，40/60纤维具有较大的热收缩率，50/50纤维具有较好的卷曲率、卷曲牢度和拉伸弹性回复性能。

The testing results is that the bilateral composite fiber with composite ratio 40 / 60 has higher shrinkage properties , and the fiber with composite ratio 50 / 50 has better crimp rate , crimp resistant and tensile elastic recovery .

PASTER的断裂强力、断裂伸长和卷曲弹性率低于常规涤纶和ECDP，进一步证明结晶度下降，分子结构变得疏松、柔软。

The breaking strength , breaking elongation and crimp elasticity of PASTER are lower than conventional polyester fibre and common ECDP fibre ' s. It proved that crystallinity degree decreased , the molecular structure becomes loose and soft .

分析了纤维的纤度、长度、卷曲度、含油率和含湿率等表面性能对非织造布梳理质量的影响。

The paper presents that the surface performance of fiber influence carding quality of nonwovens , such as denier , length , crimp frequency , oil content and moisture content .

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。

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

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 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 .

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；

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