What is Vat Dyeing Process Overview about?

Vat dyes are water-insoluble dyes that can be converted to a soluble state for dyeing cotton, offering excellent fastness properties but at a higher cost compared to other dyes. They are classified into different groups based on application methods, requiring varying temperatures and concentrations of caustic soda and sodium hydrosulphite. The dyeing process involves vatting, dyeing, oxidation, and after-treatment to ensure proper fixation and fastness of the dye on the fabric.
