ABSTRACT:
A process for the level exhaust dyeing of polyester fiber textile material is accomplished by dissolving unfinished disperse dyestuff synthesis material in as high a concentration as possible in an organic solvent miscible with water. This solution is forced into an aqueous liquor already at a dyeing temperature of 90.degree. to 140.degree. C. and already circulating through the polyester fiber textile material. Dyeing of the material then occurs in the usual manner.
