The Influence of Electrode for the Electrochemical Dyeing of Cotton Fabric

Using nickel electrode as dyeing electrode, sodium carbonate as fixing alkali and anodic region as dyeing region, cotton fabric was electrochemically dyed by reactive blue X-BR under external DC power supply. By comparing the dyeing rate, fixation rate, polarization curve and evenness of the two dyeing methods, it can be concluded that the electrochemical dyeing effect of nickel electrode on reactive dye cotton fabric is far better than that of traditional reactive dye dyeing method.
