摘要
对自制超支化聚酯用十六烷基环氧丙基二甲基氯化铵(EDAC16)进行季铵化改性,得到碱减量促进剂超支化聚酯季铵盐(QHPE),并将其应用于涤纶织物的碱减量处理中。结果表明,该促进剂对涤纶碱减量有较明显的促进作用,QHPE用量、烧碱用量、处理时间和处理温度对涤纶织物碱减量有一定的影响,促进剂的用量宜控制在0.016 g左右。
Alkali deweighting promoter of quaternary ammonium salts （QHPE） is prepared by quaternized modification of self- made hyperbranched polyester with epoxypropyl hexadecyl dimethyl ammonium chloride, and its application to polyester dew- eighting is carried out. The results show that QHPE has a significant promoting effect in deweighting process. The dosages of QHPE and sodium hydroxide, treating temperature and time exert some influence on polyester deweighting, and the optimum QHPE dosage is 0.016 g.
