(1/2) > >>

Md. Al-Amin:
The word vat means, ‘Vessel’. The dyes take their name from vatting. The vat dyes are naturally coloring matter and kept in wooden vat and make solubilise vat dyes by the process of formantation – so it is called vat dyes. They are applied in a special kind of a dyebath in which the dye is reduced to a soluble form by means of a strong reducing agent, such as hydrosulphite. The vat dyes are insoluble and cannot be used directly and requires vatting. Among all the dyes, it has the best fastness properties.
