摘要
以丙烯酰胺(AM)、烯丙基缩水甘油醚(AGE)和二甲基二烯丙基氯化铵(DMDAAC)为原料,采用过硫酸铵为引发剂,合成了三元共聚物P(AM-AGE-DMDAAC)。共聚物P(AM-AGE-DMDAAC)优化的合成工艺条件为:单体摩尔分数比n(AM)∶n(AGE)∶n(DMDAAC)=1∶1∶5,反应温度80℃,反应时间5 h,引发剂质量分数1.5%。将该共聚物用作棉织物阳离子改性剂,研究了改性剂浓度、焙烘温度和时间对染色性能的影响。结果表明,与传统活性染料染色工艺相比,在无盐染色的条件下,经合成的阳离子改性剂处理的织物,上染率有较大提高,干摩擦牢度可达到4级,湿摩擦牢度可达到3～4级,皂洗牢度可达4～5级。
Using acrylamide （AM）, dimethyl diallyl ammounium chloride （DMDAAC） and allyl glycidyl ether （AGE） as reactants, ammonium persulfate as initiator, terpolymer P （AM-AGE-DMDAAC） is prepared. The optimum synthesis conditions of the copolymer P（AM-AGE-DMDAAC） are defined as follows： the ratio of AM to AGE to DMDAAC =1 ： 1： 5, initiator 1.5% of reaction at 80 ℃ for 5 h. The copolymer is used as a cationic modifier of cotton fabric. The influences of modifier concentration, curing time and temperature on dyeing behavior are researched. Compared with the conventional reactive dyeing process, the dye uptake of modified cotton without salt are significantly improved, and color fastness are better with 3 - 4 level of wet rubbing,4 level of dry rubbing and 4 - 5 level of soaping.
