Vat dyes are dyes that are reduced under alkaline conditions to color the fiber, and then oxidized to return to the original insoluble dye on the fiber for dyeing. They are used to dye cellulose fibers; insoluble vat dyes are made into sodium sulfate salts to become soluble vat dyes, which are mainly used for cotton printing.
