[Applications]: Application of vat dyestuff is not so easy like direct or reactive dyes. The application involves a lot of chemistry - such as oxidation, reduction, pH control and so on. Even the dissolution of the dyestuff involves a great technique of reduction using adequate quantities of caustic soda and sodium hydrosulphite.

There are several methods available for the application of vat dyes to yarn and fabric.

The Vat dyes are having all around fastness properties which cannot be possible in any class of dyes .the only problem in this class is slightly poor rubbing fastness.which can be increased by special after treatment.

[ Use ] :  Vat dyes are, as a class, the most light-fast of all dyes. However, not all individual vat dyes are equally resistant to light. The following are lightfastness ratings for the unmixed vat dyes sold by us.
