  • What is the reaction mechanism of reactive dyes?


    Reactive dyes are used for cellulose fiber dyes, generally through three stages of adsorption, diffusion and fixation:There is no covalent bond reaction between the dye and the fiber during the adsorption and diffusion process. When the alkali agent is added to make the pH of the dye bath alkaline, Read More
  • What are the major categories of reactive dyes?


    The active groups are monochloro-s-triazine and vinyl sulfone heterobi-reactive dyes. The commodity categories are named differently, mainly including M type, B type, RR type, BF type, BH type (partial), etc. The recommended dyeing temperature is 60~80℃. Due to the synergistic effect of two differen Read More
