摘要
通过正交试验确定了活性深蓝 K- R与壳聚糖反应的最佳工艺条件 :p H为 7,温度80℃ ,反应 5 h,搅拌速率 5 0 0 r/ min.活性艳蓝 KN- R与壳聚糖反应的最佳工艺条件 :p H为 8,温度 5 0℃ ,反应 2 .5 h,搅拌速率 5 0 0 r/ min.并确定了此高分子染料染色的最佳工艺条件 :焙烘温度 1 5 0℃ ,焙烘时间 3～ 5 min.通过对比发现 ,此高分子染料的摩擦牢度、皂洗牢度明显好于普通涂料 ,特别是摩擦牢度 ,比普通涂料提高 1～ 2级 .
The process for preparing polymeric dyes was studied. By orthogonal test, the best condition for the reaction of reactive blue dyes K R and chitosan was found to be temperature 80℃,pH 7,stirring rate 500 r/min ,reative time 5 h;the best condition for the reaction of reactive blue dyes KN R and chitosan was found to be temperature 50℃,pH 8,stirring rate 500 r/min,reative time 2.5 h.In addition, the best baking condition was found to be temperature 150℃,time 3~5 min.By compared with common pigment, the polymeric dyes has better rubbing fastness and washing fastness. The rubbing fastness is 1~2 band higher than common pigment.
