ABSTRACT:
Textile materials such as fiber and cloth can be dyed more satisfactorily with sulfur dyes or sulfurized vat dyes by allowing an organic mercapto compound and/or an organic sulfur compound capable of generating mercapto groups under dyeing conditions to be present in dye baths. Still more improved dyeing results may be obtained by allowing a sulfite salt compound to be further present in such dye baths.
