[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.
