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

阳离子Gemini表面活性剂对超细聚酯纤维碱水解的影响

The results of experiments showed that by basic hydrolysis procedure,the synthesis time is shorten from 45-50 min to 30-35 min,uncorrected synthesis yield can be increased from 45%-50% to 60%-65%,and the preparing procedure is stable.
