Textile dyeing process of cellulosic fibers and their blends and polyester and its blends with reused dyeing baths, without any later depuration treatment

Abstract

a textile dyeing process o f cellulose fibers and polyester and their respective blends with other fibers in reused dyeing baths, without carrying out any intermediate depuration treatment, with reactive and direct dyes for the cellulose fibers and disperse dyes for the polyester, reusing both the water already used in a previous dyeing and all added products that have not been absorbed by the textile substrate, as well as the rest o f the disperse dyes that had not been depleted in the previous dyeing.
