ME Dyes (Bifunctional Dyes)

These are mixed bifunctional reactive dyes where Vinyl Sulphone group is linked to chromophore through a monochloro triazine group as a bridge link. They are applicable on cellulosic material at lower dyeing temperature of 60ºC. The main features of Bifunctional Dyes are as under:

  • The dye-fibre bond between Vinylsulfone group and cellulose is stable to acid hydrolysis, so that stability of dyed goods in industrial acidic atmosphere is very good with the time lapse.
  • The dyes which are not fixed during the dyeing process can be washed off easily because the hydrolysis dye has low substantivity and thus there is a little risk of staining of adjacent whites.
  • Excellent levelling properties.
  • Better reproducibility in dyeings.
  • High exhaustion and high fixation efficiency.
  • Good all round fastness properties.Bi-functional dyes are applicable on cellulosic materials by dyeing as well as printing methods.
