摘要(Abstract)：
以聚醚酯四氢呋喃均聚醚-聚对苯二甲酸丁二醇酯(PTMG-PBT)和PBT为原料,按照50∶50的质量比,通过熔融纺丝制备了具有高度自卷曲的并列复合弹性纤维。研究复合纤维的制备工艺参数,包括牵伸倍数、牵伸热定形温度、热处理温度和时间对并列复合弹性纤维力学性能和卷曲性能的影响。试验结果表明:牵伸倍数的增大能够极大地改变复合纤维的卷曲形貌,改善卷曲性能以及显著提高复合纤维的模量和强度;牵伸温度140℃时,复合纤维力学性能和卷曲性能最佳;热处理温度100℃、热处理时间5 min时,复合纤维的卷曲率和卷曲回复率达到最佳,分别为60%和53%。
Using PTMG-PBT and PBT as raw materials, according to the mass ratio of 50∶50, the side-by-side composite elastic fiber with a high degree of self-crimp was prepared by melt spinning, and the influ-ence of preparation process parameters of composite fiber, including drafting ratio and drafting-setting tem-perature, heat treatment temperature and time on the mechanical properties and crimp performance of thecomposite fiber was studied. The experimental results show that the increase of the drafting ratio can greatlychange the crimp morphology and improve the crimp performance of the composite fiber and significantly in-crease the modulus and strength of the composite fiber. When the drafting temperature is 140 ℃, the me-chanical proprties and crimp properties of the composite fiber are the best. When the heat treatment temper-ature is 100 ℃ and the heat treatment time is 5 min, the coil curvature and crimp recovery rate of compositefiber reach the optimal value of 60% and 53%, respectivelyAbstract:.
