摘要
将活性深蓝K-R接枝到聚乙烯醇侧链上生成的产物先后经过沉降和缩醛化反应制备得黏度、流动性适中的高分子染料,将其用于涤棉织物的染色.通过单因子实验研究了接枝反应时间、反应温度、反应体系pH值对染色织物摩擦牢度、皂洗牢度的影响.通过正交实验确定了接枝反应优化工艺条件:温度75℃,时间3.5h,pH值8.5.
Polyvinyl alcohol and reactive blue K-R dye was used to synthesize a new polymeric dye.This new polymeric dye can be used for dyeing polyester/cotton fabric.In experiments,by rubbing fastness,soaping fastness to detect macromolecular synthesis of dyes and dyeing.By single factor experiment and orthogonal experiment,the optimum polymer dye synthesis is obtained,namely polymer dey synthesis of optimum： the time is 3.5h,the temperature is 75℃ and the pH is 8.5.
