标 题 :Process for the level exhaust dyeing of polyester fibers
发明人：GLANDER SIEGFRIED
权利人:HOECHST AG
摘要: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 DEG to 140 DEG C. and already circulating through the polyester fiber textile material. Dyeing of the material then occurs in the usual manner.
