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:
1. 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.
2. 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.
3. Excellent levelling properties.
4. Better reproducibility in dyeings.
5. High exhaustion and high fixation efficiency.
6. Good all round fastness properties.
Bi-functional dyes are applicable on cellulosic materials by dyeing
as well as printing methods.
