Optimization and assessment on indirect electrochemical reduction of indigo
Purpose
An indirect electrochemical reduction and dyeing with indigo were carried out here to solve problems of low dye reduction rate and poor dyeing depth in the current electrochemical dyeing process.
Design/methodology/approach
Response surface analysis tests were performed to evaluate the effects of ferrous sulfate concentration, medium concentration, sodium hydroxide concentration and reduction time on the reduction efficiency of indirect electrochemical reduction of indigo.
Findings
The conditions obtained by design-expert optimization showed that the concentration of FeSO4·7H2O has the most significant effect on the reduction performance of dye liquor. Under the optimized electrochemical reduction dyeing process, the rate of dye reduction could be reached 91.21 per cent and the K/S value of indirect electrochemical dyeing of indigo can be achieved to 12.96, which is increased by about 9.56 per cent compared with that of Na2S2O4 dyeing with the same color fastness basically.
Research limitations/implications
The recyclability and biodegradability of the dye remain to be explored.
Practical implications
The strategy presented here can be developed to replace a substantial part of electrochemical dyeing with optimized product quality and reduced environmental pollution in denim production.
Social implications
The strategy presented here can be developed to replace a substantial part of electrochemical dyeing with optimized product quality and reduced environmental pollution in denim production.
Originality/value
Application of the Fe(II)-DGS-Abal B complex media system in the indirect electrochemical reduction of indigo.
