| 摘 要： | 通过SEM观察及失重率、拉伸曲线和弹性回复率等指标的测定,研究了碱处理对PTT、PET等纤维形态结构特征和力学性能的影响。结果表明:高温碱处理可使PTT纤维表面出现明显的微坑穴,对其力学性能的损伤比室温碱处理明显增大;在室温下,PET纤维的耐碱性优于PTT纤维;高温下,PTT纤维的耐碱性优于PET纤维;在合适的温度和浓度下,PTT纤维可以安全地经受碱液的作用,能维持良好的力学性能。

| Abstract: | This paper studied the effect of alkali treatment on morphological structure and mechanical properties of PTT,PET fiber through SEM,loss of weight,tensile curve and resilient-elasticity recovery.The experiment results show that hightemperature alkali treatment can make surface of PTT fiber dissolve to form a lot of micro-holes,and bring about much more loss of mechanical properties than room-temperature alkali treatment.Alkali resistance of PET fiber is superior to that of PTT fiber in room-temperature,but in high-temperature alkali resistance of PTT fiber is superior to that of PET fiber.Through alkali treatment in appropriate temperature and concentration,PTT fiber can maintain high mechanical properties. |
