摘要： Disclosed herein are poly(phenylene sulfide) fibers having a tensile strength of at least 3.5 g/d, a knot tenacity of at least 2 g/d, a loop tenacity of at least 3.5 g/d, the number of abrasion cycles until breaking in a flexing abrasion test of at least 3,000 times, and the number of repeated flexings until breaking in a flexural fatigue test of at least 150 times. A process for the production of poly(phenylene sulfide) fibers, which comprises melt-spinning a poly(phenylene sulfide), stretching the resultant unstretched filaments at a draw ratio of 2:1 to 7:1 within a temperature range of 80.degree.-260.degree. C., and heat-treating the stretched filaments for 0.1-30 seconds under conditions of a take-up ratio of 0.8:1 to 1.35:1 in a dry heat atmosphere exceeding 285.degree. C., but not exceeding 385.degree. C. is also disclosed.
摘要翻译：本文公开的是具有至少3.5g / d的拉伸强度，至少2g / d的结强度，至少3.5g / d的环韧度，直到断裂的磨损循环次数的聚（苯硫醚）纤维在至少3000次的弯曲磨损试验中，以及直到在弯曲疲劳试验中断裂至少150次的反复弯曲次数。一种生产聚（苯硫醚）纤维的方法，其包括熔融纺丝聚（苯硫醚），在80℃的温度范围内以2:1至7:1的拉伸比拉伸所得的未拉伸长丝， 260℃，在超过285℃，但不超过385℃的干燥热气氛中，以0.8:1-1.35:1的卷取比条件，将拉伸的长丝热处理0.1-30秒也被披露。
