From the perspective of the biological compatibility of parent dyes, the development of non-mutagenic dyes and biomimetic dyes for fibers was discussed. Effective approaches of producing reactive dyeing with high fixation and the feasibility of nearly 100% chemical combination between dye and fiber by crosslinking dyeing were studied. Also discussed were eco-friendly dyeing processes, including salt-free dyeing with reactive dyes, dyeing with vat dyes and sulfur dyes by biochemical or electrochemical reduct...
