摘　　要：科学准确地测定涤纶BCF的卷曲性能对提高产品质量及满足客户要求意义重大,以显现温度、显现时间、预加张力、平衡时间、重负荷作为试验因素,以卷曲收缩率、卷曲模量、卷曲稳定度、热卷曲伸长率为判断指标,对涤纶BCF进行卷曲性能测试方法的探讨。结果表明:预加张力、显现温度对卷曲收缩率、卷曲模量及热卷曲伸长率影响显著,重负荷对卷曲稳定度的影响很大。随着显现温度的升高,卷曲收缩率、卷曲模量先增加,而后逐渐降低,热卷曲伸长率逐步增加,而后略减小。随着预加张力的增大,卷曲收缩率、卷曲模量及热卷曲伸长率逐渐减小,卷曲稳定度随重负荷的增加快速降低。To scientifically and accurately measure crimp property of polyester BCF is of great significance for improving product quality and meeting customers＇ requirements. This paper uses apparent temperature, presentation time, pre-tension and equilibrium time, heavy load as experimental factors and adopts crimp contraction rate, crimp modulus, crimp stability, thermal crimp elongation as judging indicators to discuss crimp property testing methods for polyester BCF. The results show that： the pre-tensior~ and apparent temperature have significant effect on the crimp contraction rate, crimp modulus and thermal crimp elongation, while crimp stability is affected greatly by heavy load. As the temperature rises, the crimp contraction rate and crimp modulus increase first and then decrease gradually; the thermal crimp elongation increases and then decreases slightly; With the increases in pre-teqsion, the crimp contraction rate, crimp modulus and thermal crimp elongation decreases gradually. As the heavy load increases, crimp stability decreased rapidly.
