| 摘 要： | 采用TG-DSC联用技术对聚苯硫醚(PPS)纤维在N2氛围中的热分解行为进行分析。TG和DTG研究发现:PPS纤维在500℃以前基本无失重,最大失重发生在520～600℃之间,此后为慢失重过程。DSC分析发现:在整个失重过程中,PPS纤维发生的并不是单一的热分解反应。此外,对PPS纤维进行了热处理研究,探讨了纤维干热收缩率、强度保持率与热处理温度和热处理时间的关系。

| Abstract: | The thermal decomposition behavior of PPS fibers was analyzed using TG-DSC coupling technology in N2. Through the study on the TG and DTG curves, it was found that there was no weight loss of PPS fiber before 500 ℃, the greatest weight loss appeared between 520 ℃ and 600 ℃, and after that it was a process of slow weight loss. DSC curves exhibited that the thermal decomposition reaction of PPS fibers was not single in the whole process of weight loss. Moreover, PPS fibers had been experimented on heat treatment, and some relations between dry heat shrinkage, tenacity retention and heat treatment time and heat treatment temperature were studied. |
