ABSTRACT:
The present invention is a method for processing dye-liquors, in particular dye-liquors for textile dyeing and post-treatment facilities. In particular, the present invention makes it possible to minimize the waste portion, and even entirely eliminate dyeing accessories, while textiles are treated in one or more subsequent dyeing chambers with heated dye liquors. The textiles to be treated are pulled in continuous transit, in one direction, through the associated equipment. Direction-reversing systems ensure a plurality of lengths of said textile are simultaneously in the dyeing chamber while the dye liquor is constantly cleaned and replenished by an apparatus which removes and reintroduction the dye-liquor in the dyeing chamber.
