中文摘要：

采用阳离子染料对腈纶织物进行原位矿化工艺染色，通过单因素试验分析偶合剂用量、矿化温度及时间对染色织物的K／S值及染色残液脱色率等的影响。结果表明，当偶合剂XBQ及XYQ质量分数分别为1．6％（omf）和8．0％（omf），矿化温度及时间分别为70℃和40min时，腈纶织物经原位矿化染色可以获得与传统染色工艺一致的染色深度和染色牢度。相比传统染色工艺，原位矿化染色的残液脱色率可达90％，染后残液CODCr值降低50％以上，节水80％，满足染整加工对深度节水减排的需求。

英文摘要：

The dyeing of acrylic fabrics with cationic dyes is performed in the in-situ mineralization process. The effects of coupling agent concentration, mineralization temperature and time on K/S value of the dyeings and the decolorization rate of the effluent are analyzed by single factor test. The results show that the dyeing depth and color fastness of the fabrics dyed with the in-situ mineralization process are the same as those of traditional dyeing process, under the condition of the dosages of XBQ and XYQ are 1.6% and 8.0% （omf） respectively, and treating at 70℃ for 40 rain. Compared with traditional dyeing process, the decolorization rate of the effluent after in-situ mineralization dyeing can be up to 90% and the CODer value is reduced by more than 50%, water consumption is reduced by 80%. So the in-situ mineralization dyeing process can meet the needs of dyeing and finishing on the advanced water-saving and emission reduction.
