ABSTRACT:
Process for the continuous dyeing of synthetic fibre materials from organic solvents, wherein the material, preheated to at least 100.degree. C., is impregnated with a halogenated hydrocarbon impregnating liquor containing dyestuff or optical brightener to give a liquor absorption of more than 100%, and is then passed through a vapor zone filled with halogenated hydrocarbon at a temperature above the boiling point of the halogenated hydrocarbon in such a manner that during passage of the material through this zone the liquor becomes concentrated on the material, whereby
