Abstract

1421499 Solvent dyeing HOECHST AG 7 June 1973 [7 June 1972] 27233/73 Heading D1B Synthetic fibrous material is dyed at a temperature above 20‹C with the dye 2, 6-dicyano- 4-nitro-2'-acetamido-4' diethylamino - azobenzene dissolved in an organic solvent. The substrates may be polyester, polyacrylonitrile or cellulose triacetate and cellulose 2¢ acetate. Preferably the solvents are water-immiscible and have boiling points between 40 and 150‹C, specified solvents being tetrachloroethylene, chloroform, methylene chloride, di-tri- and pentachloropropanes, fluorobenzene, chloro-benzene and chlorotoluene. The process may be continuous.
