摘　　要：分析了不同张力和温度条件下,PET/PTT单丝和复丝的卷曲形貌和卷曲弹性参数。结果表明:随着热处理张力的增加,单丝的卷曲数和卷曲半径减小,单丝和复丝的卷曲伸长率减小,卷曲弹性回复率增加,卷曲模量增加;随着热处理温度的增加,单丝的卷曲数增加,卷曲半径减小,单丝和复丝的卷曲伸长率减小,卷曲弹性回复率增加,卷曲模量增加;在温度100～120℃且张力较小的条件下进行热处理时,PET/PTT纤维的单丝和复丝的卷曲弹性较好。The crimp shape and crimp elasticity characters of the PET/PTT monofilaments and muhifila- ments under diffcrent tension and temperature were analyzed. As the tension of the heat treatment rose, the crimp frequency and the crimp radius of the monofilament went down, the crimp elongation rate went down, the crimp recovery rate and the crimp modulus of the monofilament and multifilament went up. As the temperature of the heat treatment rose, the crimp frequency increased and the crimp radius decreased. And the crimp elongation decreased, the crimp recovery rate and the crimp modulus of the monofilament and multifilament increased. When the temperature was 100-120 ℃ and the tension was little, the crimp elasticity of the PET/PTT monofilaments and multifilaments were better.
