| 摘 要： | 通过对不同捻度和混纺比的PBST(聚丁二酸-共-对苯二甲酸丁二醇酯)与棉包芯纱拉伸回复性能的分析,探讨了捻度和混纺比对PBST包芯纱回弹性能的影响.在捻度相同、PBST纤维相同的条件下,PBST包芯纱的拉伸弹性回复性随着棉纤维的增加而减少;在纱线混纺比相同时、PBST包芯纱的拉伸弹性回复率随着捻度的增加呈先增后降的趋势.采用捻度为500捻/m和40/60的混纺比纺制PBST/棉包芯纱时,纱线的拉伸弹性回复性能较好,并且在小变形下,PBST包芯纱能保持良好的拉伸回复性.这对PBST包芯纱的开发和应用具有一定的参考价值.

| Abstract: | The stretching resiliency of PBST/cotton core-spun yarn was analyzed with different twist and blending ratio, and their influence on the PBST/cotton core-spun yarn was discussed. It was concluded that the stretching resiliency of PBST/cotton core-spun yarn was decreased with the increase of cotton fiber under the same twist and PBST fiber condition. And it was firstly increased and then decreased with the increase of twist under the same blending ratio condition. According to the experiment, PBST/cotton cor... |
