摘　　要：借鉴苯胺黑黑地防染印花工艺中的氯酸钠和黄血盐钾氧化组合,作为靛蓝氧化拔染剂,以柠檬酸为酸性介质,可以实现靛蓝牛仔布的氧化拔染印花,还可以用于靛蓝套染硫化染料或直接染料地色拔染印花等。生产中根据拔染效果和织物强力,可以调整氯酸钠和黄血盐钾用量和酸的用量,比商品靛蓝拔染剂如拔染剂C-100、拔染剂JN等更有优势,印花成本低,制浆采用冷法制备,简便快捷、汽蒸时间短、工艺条件可控、重现性好,能有效控制织物的强力损失。无甲醛使靛蓝拔染印花获得新生。In view of the combination of sodium chlorate and yellow prussiate of potash used in black-based dye-resist printing process for aniline black as oxidative discharging agent, oxidative discharge printing of denim fabric can be realized through citric acid used as acidic medium. This kind combination can also be applied in the discharge printing based on sulfur dye or direct dye used with indigo. The dosage of sodium chlorate, yellow prussiate of potash and acid can be adjusted according to discharge effect and fabric strength in manufacture. It is superior to commercial discharging agents such as discharging agent C-IO0 and discharging agent JN due to low cost. The paste is prepared by cold method, which presented advantages as simpleness, rapidness, short steaming time, controlled technological conditions, good reproducibility and effective control the loss of fabric strength. Moreover, the formaldehyde-free process recreates indigo discharge printing.
