阳离子聚合物固色应用研究

Study of Fixation Application with Cationic Polymer

以二甲基二烯丙基氯化铵（DMDAAC）为原料，以过硫酸钾为引发剂，通过共聚合成了一种符合环保要求的水溶性阳离子聚合物固色剂．并将其应用于活性染料固色处理。测试并分析了固色剂用量、固色温度、时间对固色效果的影响．优化了固色工艺。测试并比较了自制的水溶性阳离子聚合物固色剂和无醛固色剂Fix-600的固色效果。结果表明．用水溶性阳离子聚合物固色的最佳工艺为：固色剂用量为3～4g／L，固色温度为60℃，时间为30min，浴比为1：30；水溶性阳离子聚合物作为固色剂应用于活性染料染色织物的固色处理中．耐摩擦色牢度、耐洗色牢度均有所提高。

With dimethyl dialyl ammonium chloride（DMDAAC） as raw material and potassium peroxodisulfate as initiator, the water-soluble cationic polyester fixing agent which met the environmental needs was synthetized through copolymerization. And the fixing agent was applied to fixing process of the fabric dyed by reactive dyes. The effects of the dosage of fixing agent, temperature and time on fixing effect were tested and analyzed, and the fixing process was optimized. The fixing effect of homemade fixing agent and formaldehyde-free fixing agent Fix-600 were tested and compared. The results show that the optimal process of fabric by water-soluble cationic polyester fixing agent is that the dosage of fixing agent is 3-4 g/L, fixing temperature is 60 ℃,time is 30 minutes, and the ratio is 1：30; when water-soluble cationic polyester as fixing agent is applied to fixing process of the fabric dyed by reactive dyes, color fastness to rubbing and washing both increase.
