【 摘 要 】

The indirect electrochemical reduction dyeing of cotton fabric with indigo are carried out in this work using the synergistic complexation system of Fe(II)-DGS-Abal B. The influences of concentration of FeSO4•7H2O, C6H11O7Na, Abal B and NaOH on dyeing performances are discussed. The concentration of NaOH is found to be the main influence factors and the rate of dye reduction (Re) could be achieved to 90.88% in the optimized conditions. Compared to the traditional dyeing with Na2S2O4, K/S value of the electrochemical dyeing of cotton fabric is increased by 6.14%, and the color fastness is basically the same as the traditional dyeing process.
