ABSTRACT:
The present invention relates to a novel exhaust-dyeing process to obtain level dyeings which is characterized by the step of regulating the parameters that affect the rate of adsorption of the dye onto the substrate in order to prevent the rate of bath exhaustion as a function of the number of cycles of dye liquor and/or substrate from exceeding a predetermined limit. The invention also relates to an apparatus for effecting said process.
