  author={Pan Ji},
Factors exerting influence on dyeing properties of cotton fabric in electrochemical process are discussed, such as the voltage, dyeing temperature, dyeing time and fixing time. The parameters of the optimum dyeing process are determined. Relationship between the salt-free electrochemical dyeing and structure of K-reactive dyes aree also researched. The optimal process of the K-reactive dyes with salt-free electrochemical dyeing is defined as follows: the voltage of 5~7 V, dyeing temperature of… CONTINUE READING
