阳离子Gemini表面活性剂对超细聚酯纤维碱水解的影响

Effects of cationic gemini surfactants on basic hydrolysis of polyester superfine fiber

研究了2种阳离子Gemini表面活性剂对超细聚酯纤维的碱水解作用,探讨了超细聚酯纤维碱水解规律及其反应动力学.结果表明:阳离子Gemini表面活性剂(DC2-12、DC2-16)对超细聚酯纤维水解有明显的促进作用;在等温条件下,超细聚酯纤维的水解反应符合二级速率方程.

The effect of two cationic gemini surfactants on basic hydrolysis of polyester superfine fiber was investigated, and the rule of basic hydrolysis and the reaction kinetics of polyester superfine fiber were also discussed, The results showed that the cationic gemini surfactants （DC2-2,DC2-16）had an obvious promoting effect on polyester superfine fiber; and the hydrolysis reaction fit the secondary dynamic model under isothermal condition.
