Abstract

1521229 Treatment of wash liquors from dyeing processes CIBA-GEIGY AG 12 Nov 1976 [21 Nov 1975] 47306/76 Heading C1C [Also in Division D1] Cationically modified cellulose containing material is used to effect decolorization of wash liquors from dyeing processes containing watersoluble anionic dyes, the decolorized water then being recycled to the dyeing process. Preferably the washing liquor is at 30‹-100‹ C. at pH value of 3 to 9. Purification of the water being effected by fluidized bed or fixed bed processes. Anionic dyes and optical brighteners may be removed from the wash water by cationically modified cellulose materials in which the hydroxyl groups have been at least partially replaced by quaternary ammonium groups of formula in which Alk is a C 1-5 alkyl radical, An<SP>-</SP> is an anion by reaction with an epoxypropylammonium salt.
