| 摘 要： | 以POY-DT和FDY工艺获得的不同规格、本色和有色PET/PTT复合纤维为研究对象,考察了纤维规格、工艺路线和色母粒对PET/PTT复合纤维的卷缩性能的影响,表征了复合纤维的轴向形态结构与断面结构,研究了纤维力学性能。结果表明,PET/PTT复合纤维的卷曲性能随着线密度的增加而升高,在130dtex附近达到峰值;本色复合纤维的卷曲收缩率、卷曲模量和弹性恢复率均高于有色复合纤维,而卷曲稳定度和紧缩伸长率则有色纤维较高,POY-DT工艺得到的复合纤维的卷曲收缩率、卷曲模量、紧缩伸长率、卷曲稳定度、断裂强度高于FDY工艺得到的纤维,但其弹性恢复率低于FDY纤维;经过湿热处理后的复合纤维的卷缩半径明显减小,卷缩性能得到提升;通过复合纤维断面SEM照片观察到,PET与PTT两相间界面黏合良好。

| Abstract: | PET/PTT conjugated yarn with different specifications and different colors was obtained by POY-DT and FDY process route.The influence of specification,process route and master batch on crimp contraction property of PET/PTT conjugated yarn was investigated and the axial morphostructure,cross section and the mechanical property of the yarn were characterized.As a result,the crimp contraction of PET/PTT conjugated yarn is rised with the increasing linear density and reach its maximum at 130 dtex.The crimp cont... |
