摘　　要：为降低活性染料印花的水耗能耗和电解质与氨氮排放,借助泡沫法给湿过程对印花棉织物施加碱剂,随后直接湿蒸固色。探讨了所制备泡沫的耐碱稳定性,研究汽蒸时间和碱剂用量对活性艳红X-3B泡沫法给碱-湿蒸印花的影响,并分析综合印花效果。结果表明:含4g/L APG10、12g/L CMC-Na的发泡原液在pH值为12.92时,泡沫的初见液时间和破裂半衰期仍分别高达16.8min和67.5min;质量分数为3%的活性艳红X-3B采用泡沫法给碱-湿蒸印花的适宜条件为碳酸钠40g/L、102℃汽蒸4min;所得织物具有良好的颜色递深性、花型轮廓清晰度和图案颜色均匀性,干、湿摩分别在4~5级和3级及以上。In order to reduce the water and energy consumption as well as the electrolyte and ammonia nitrogen discharge in printing with reactive dyes,the alkali was added onto the printed cotton fabric by pre-weting with foam,fllowed by wet-steaming fixation.The alkali-resistant stability of the foam system was studied.The effects of steaming time and alkali dosage on the wet-steaming fixation of reactive brilliant red X-3B prints with application of alkali in foam form was investigated,and the comprehensive printing effects were analyzed as well.The results show that for foaming stock solution containing 4 g/L of APG10 and 12 g/L of CMC-Na,even though the pH value reaches 12.92,the drop emergence time and half-life period of decay of foam can still reach 16.8 minutes and 67.5 minutes respectively.The appropriate conditions for printing cotton fabric with 3%of reactive brilliant red X-3B using the aforementioned process were 40 g/L of sodium carbonate,steaming at 102℃for4minutes.Thecotton prints have good color build-up property,acceptable outline sharpness and color levelness,the color fastness to dry and wet rubbing can reach level 4~5 and level 3 or above,respectively.
