Vat dyes dyeing process

Vat dyes do not dissolve in water, while when reduced to be leuco salt by reducing
agent under alkaline conditions, they can dissolve in water and get feature of
immediacy with cellulose fibers, which is the way to achieve the purpose of dyeing.
Then stable shade and good color fastness would come out via oxidation and soaping.



Reduction of dyes

Insoluble reducing dye will change into soluble leuco.

Different levels of the best staining methods are brought out according to the
reduction dyes’ reduction potential and level of its immediacy to fibers.



Dye-uptake of leuco

The leuco is absorbed by fiber and then it is diffusing into the fiber.

It is necessary to use soft water or softened water in dyeing process. Hereby it is
suggested to add the water softener for 1g/L to some poor quality cotton calcium,
magnesium ions, but also the iron, copper ions which are absorbed by the pipe into
the dye bath, and finally keep the solubility of leuco.
