SHIVITEX BI FUNCTIONAL DYES |
|
|
|
|
These are mixed bifunctional reactive dyes where Vinyl Sulphone group is linked to chromophore through a Reactive group as a bridge link. They are applicable on cellulosic material at lower dyeing temperature of 60ºC. |
|
The main features of SHIVITEX 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.
|
SHIVITEX Bi-functional dyes are applicable on cellulosic materials by dyeing as well as printing methods. |
