无甲醛固色剂及其制备方法
摘要：
本发明涉及一种无甲醛固色剂及其制备方法，该固色剂主要用于棉等纤维素纤维的固色。现有的无甲醛固色剂的固色性能和效果均不佳，且生产工艺较为复杂。本发明的特征在于：包括SO 2 和质量浓度在55-65％之间的CH 2 ＝CHCH 2 (R 1 R 2 )N + CH 2 CH＝CH 2 X - 水溶液，该SO 2 和CH 2 ＝CHCH 2 (R 1 R 2 )N + CH 2 CH＝CH 2 X - 的摩尔比在1∶(0.9-1.1)之间，其中R 1 和R 2 分别为C 1 ～C 5 烷基中的一种，X为卤素；所述固色剂水溶液在25℃时的黏度为10000-12000cps。本发明不含甲醛，绿色环保，固色剂的固色效果好，固色牢度优良，制造简单，生产成本。
摘要（英）：

The invention relates to a formaldehyde-free color fixing agent and a preparation method thereof. The formaldehyde-free color fixing agent is mainly used for fixing the color of cellulose fiber of cotton, and the like. The prior formaldehyde-free color fixing agent has poor color fixing performance and effect and complex production technology. The formaldehyde-free color fixing agent is characterized by comprising SO2 and CH2=CHCH2(R1R2)N<+>CH2CH=CH2X<-> water solution with mass concentration between 55 percent to 65 percent, a mole ratio of the SO2 and the CH2=CHCH2(R1R2)N<+>CH2CH=CH2X<-> is1: (0.9-1.1), wherein the R1 and the R2 stand for one of C1-C5 alkyl respectively, the X stands for halogen, and the viscosity of the color fixing agent water solution is 10000-20000cps at 25 DEG C. The formaldehyde-free color fixing agent does not contain formaldehyde, is environmental-friendly and has good color fixing effect, good color fixing fastness, simple manufacture and low production cost.
