Vat dyes are different from reactive dyes, disperse dyes, basic dyes, acid dyes or azoic color but its application process is near similar as sulphur dyes are used for coloring cellulosic fiber specially cotton fiber.

It is widely used for run the dyeing process of cotton yarns which is used for producing jeans or denim product. The word vat is come from vessel; vat dyes can be.

Dyeing of cotton with vat dye. vat dyes are water insoluble pigment. So vatting is done for making it solubilized form. Its application inverts reduction to water soluble leuco compound, then dyeing is done& after that re-oxidation of leuco dye in the fibre to soluble pigments.

There are basic 4 steps for vat dyeing. They are—— Vatting. Indigo Sol Vat Dyes are the complex derivatives of anthraquinone and feature superior fastness properties when these are applied to cellulosic textiles. Made available in powder form, it is preferred to be used in batch dyeing method where these provide fine.

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. Stages or Chemistry or Mechanism of dyeing with vat dyes: Generally, the application of vat dyes to textile materials involves five distinct steps.

a) Aqueous dispersion: The insoluble vat dyes, in this stage dispersed in water. b) Vatting: Vatting in which the insoluble commercial dye is reduced and solidities (vatted) by using Sodium hydrosulphite (hydrose) and Sodium hydroxide (NaOH).

The Chemistry of Vat Dyes enables high school chemistry teachers to introduce their students to a fascinating area of industrial chemistry-vat dyes. Background information on the history and chemistry of vat dyes is provided along with hands-on, problem-solving activities on producing, testing, and using these chemicals.5/5(3).

Dye - Dye - Development of synthetic dyes: Perkin’s accidental discovery of mauve as a product of dichromate oxidation of impure aniline motivated chemists to examine oxidations of aniline with an array of reagents.
