摘　　要：针对醋酯纤维与涤纶染色同色性差的问题,从染色温度、染液pH值、染色浴比、保温时间、染料用量等方面研究了分散染料对醋涤面料染色性能的影响,并对染色工艺进行了优化。优化后的染色工艺为:染色温度120℃、pH值4.0、浴比1∶20、保温时间40 min。随染料用量的增加,黄AC-RL、红玉AC-GFN、藏青AC-3R染料染色平衡指数先逐渐增大后逐渐降低,最后趋于稳定;黑AC-BS染色平衡指数逐渐增大。染色后面料的耐皂洗色牢度均在4级以上,能够满足服装面料对色牢度的要求。In response to the problem of poor homochromatic dyeing of acetate fiber and polyester fiber,the effect of disperse dyes on the dyeing performance of acetate/polyester fabrics is studied in terms of dyeing temperature and time,pH value of dyeing solution,dyeing bath ratio and dye dosage,and the dyeing process is optimized.The optimum dyeing process is determined as follows:dyeing at 120℃for 40 min with pH value 4.0 and bath ratio 1∶20.The homochromatic dyeing index of yellow AC-RL,rubine AC-GFN and navy AC-3R increases gradually with the increase of the dye dosage firstly,then gradually decreases,and finally stabilizes;with the increase of dye dosage,the homochromatic dyeing index of black AC-BS gradually increases.The color fastness to soaping of the dyed fabric is above grade 4,which could meet the requirements of color fastness for garment fabrics.
