ABSTRACT:
A process is described for the removal of residues, in particular of unfixed dyes, dye degradation products, chemical and/or processing agent residues from textile substrates. For this purpose the textile substrates are arranged in an apparatus and treated there with an aqueous liquor for a predetermined time to remove residues, whereby a decreasing amount of fresh liquor is introduced into the apparatus and simultaneously a decreasing amount of liquor loaded with residues is removed from the apparatus as the treatment time progresses.
