摘　　要：用悬挂法手动测量2.22、4.44、7.78 tex氨纶丝的蠕变性能,得出氨纶丝的蠕变与时间的自然对数线性相关的回归方程,方程显著性良好。利用方程进行推算,结果表明,在一定张力下,经过较长时间后,氨纶丝蠕变产生的变形较大,可能会造成其断裂;减小氨纶丝的张力值,使氨纶丝的蠕变初值维持在一个较低的水平,尽量延缓因蠕变作用而导致其性能破坏。The creep behaviors of polyurethane filaments of 2.22,4.44,7.78 tex are tested by hanging them. Consequently, the regression equations are concluded, which describe the relationship between creep behavior and time. The result obtained from the regression equation shows that the breakage is possible for the polyurethane filaments even if the tension is soft but is continued. Therefore, the tension of polyurethane filaments should be lowered down and the initial value of creep behavior be kept in a lower level in order to reduce the possibility of demolishing their performances.
