Reactive ME Brand Dyes




RAJAFIX REACTIVE ME BRAND DYES are mixed Bifunctional reactive dyes where Vinyl Sulfone group is linked to chromophore through a mono chloro triazine group as a bridge link. They are applicable on cellulosic material at lower dyeing temperature 60oC. The main features of these 'Bifunctional' dyes are as under :

  • The dye-fibre bond between Vinylsulphone 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 hydrolyzed dye has low substantivity and thus there is a little risk of staining of adjacent whites.       
  • Excellent leveling properties.           
  • Better reproducibility in dyeing.       
  • 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.
