Abstract:
A textile dyeing process for dyeing cellulosic fibers and polyester and their respective blends with other fibers in recycled dyeing baths without carrying out any intermediate depuration treatment and using reactive and direct dyes for the cellulosic fibers and dispense dyes for polyester is described. The process recycles both the water already used in a previous dyeing cycle and all added products that have not been absorbed by the textile substrate, as well as the rest of the disperse dyes that had not been depleted in the previous dyeing cycles.
