活性染料无醛固色剂的合成及应用

Synthesis and Application Fixing Agent of Amphoteric Formaldehyde-free for Reactive Dyes

采用甲基丙烯酰氧乙基三甲基氯化铵(DMC)、丙烯酸(AC)和丙烯酰胺(AM)作为反应单体进行水相共聚,合成了一种新型无甲醛两性固色剂,以三乙醇胺作为添加剂,探索其在活性染料染色的棉织物上的固色效果,通过改变单体配比、特性粘度、浓度、pH值、焙烘温度等因素来考察它的固色性能,结果证明该固色剂能有效提高染色织物的多项牢度指标。

Using methacrylatoethyl trimethyl ammonium chloride（DMC） acrylic（AC）,and acrylamide（AM） as reactants,a new type of formaldehyde-free fixing agent was prepared in water phase.With the help of triethanolamine,its application to cotton fabric dyed with reactive dyes was researched.The effects of comonomer compositions to copolymerization,instrinsic viscosities,pH values,concentrations of fixing agent solution and baking temperatures were examined.The results showed that it could effectively improve fastness on cotton fabric.
