A substitute of Reactive Blue M-2GE was used to dye cotton fabric by exhaust dyeing.The effects of sodium sulfate dos-age,sodium carbonate dosage,fixation time,absorption time,fixation temperature and liquor ratio on dyeing exhaustion and fixation were investigated in detail.The results showed that when the dosage of sodium sulfate was 90 g/L,the dosage of sodium carbonate was 30 g/L,the fixation time was 60 min,the absorption time was 10 min and the dyeing temperature was 70℃,the fixation of the sub-stitute(Reactive Blue M-2GE-1)on cotton fabric reached 86%.The liquor ratio had little effect on the exhaustion and fixation of the dye.The liquor ratio could be as low as 1∶6 for exhaust dyeing process of Reactive Blue M-2GE-1,which could greatly reduce water consumption and energy consumption.
