摘　　要：以氯酸钠和黄血盐为氧化拔染剂,以柠檬酸为酸剂,在酸性条件下对活性染色纯棉织物进行氧化拔染印花。通过对适用于该工艺的活性染料的筛选,并进行正交试验,得到优化的氧化拔染印花工艺条件,即氯酸钠用量11%,黄血盐5%,柠檬酸6%,尿素6%,糊料6.7%,汽蒸时间9 m in。结果表明,该工艺具有优良的拔白度和较高的织物强力保留率。With sodium chlorate and potassium ferrocyanide are used as oxidative agents and citric acid as acidic agent, oxidative discharge printing for reactive dyed cotton fabric was carried out. Reactive dyes suitable for oxidative discharging are selected. The mechanism of oxidative discharge for reactive dyes is proposed. By orthogonal test, the optimized conditions were： sodium chlorate 11%, potassium ferrocyanide 5 % ,citric acid 6 %, urea 6 %, paste 6.7 %,steaming at 100℃ for 9 minutes. The results show that the good whiteness and high strength retention of dyed cotton fabric can be obtained.
