高收缩涤纶仿毛纱线的开发

高收缩涤纶纤维属于低强高伸型纤维，经热收缩后能产生不规则的自然卷曲，小伸长时弹性回复率高，手感柔软而富有弹性，可与普通纤维混纺经膨化处理后制成仿毛纱线产品。介绍了高收缩涤纶纤维的性能以及利用棉纺设备开发生产涤粘混纺仿毛纱线的工艺措施。通过试验，根据纱线仿毛效果优选了涤纶粘胶纤维的混纺比和成纱捻系数。对比分析了赛络纺复合纱、单纱及股线三种结构涤粘混纺纱线的性能及其织物的仿毛风格。

Development of High-shrinkage Polyester Wool-like Yarn

High-shrinkage polyester fiber belongs to low strength high extension type fiber, which can turn out abnormal natural crimping after thermal shrinkage, and has high elastic recovery rate when little extension, handle softness and high-elasticity, and wool-like yarn can be produced when bulking treatment high-shrinkage polyester & fiber ordinary fiber blend yarn. Performances of high-shrinkage polyester fiber and development technology measure of polyester & viscose blended wool-like yarn using cotton-spinning equipments are introduced. Through test, according to yarn wool-like effectiveness, blending ratio and yarn forming twist factor of are optimized. And performances of three structures polyester & viscose blended yarn, which are complex yarn, single yarn and compound yarn by using method of SIRO spinning, and fabric wool-like style are contrasted and analyzed.
