超支化改性棉针织物的荧光涂料染色

Fluorescent pigment dyeing of cotton knits modified by hyperbranched polymer

以丙烯酸甲酯、二乙烯三胺为原料，甲醇为溶剂，合成了一种水溶性端氨基超支化聚合物HBP—NH：；以二甲胺、环氧氯丙烷、三乙烯四胺为原料，合成了一种阳离子改性剂；用阳离子改性剂对超支化聚合物进行接枝改性，并应用于棉针织物的阳离子化改性。结果表明，棉针织物的较佳改性工艺为：阳离子改性剂和HBP—NHz的质量比为10：1，改性超支化聚合物10g／L，改性pH值10~11，室温改性60min。改性后的棉针织物用荧光涂料染色，其摩擦牢度、水洗牢度可得到改善，且织物抗紫外效果明显提高。

Hyperbranched polymer HBP-NH2 is synthesized with diethylenetriamine and methyl acrylate as raw materials and methanol as a solvent. A cationic modifier is synthesized with dimethylamine, epi- chlorohydrin and triethylenetetramine as raw materials. Then the HBP-NH2 is modified with the cationic modifier and applied to the modification of cotton knitted fabric. The results show that the optimal modi- fication process is： the ratio of cationic modifier to HBP-NH2 10： 1, 10 g/L of the modified hyperbranched polymer, pH value 10-11, modifying at room temperature for 60 rain. The modified cotton knitted fabric can obtain improved color fastnesses to rubbing and soaping and enhanced anti-UV effect after dyed with fluorescent pigment.
