Abstract

1275012 Bleaching and dyeing cellulose FARBWERKE HOECHST AG 25 March 1970 [26 March 1969] 14520/70 Heading D1B Cellulosic fibres are simultaneously bleached and dyed by impregnating with an alkaline solution of a substantive coupling component containing a diazoamino or tetrazoamino or an anti-diazotate derived from a primary aromatic amine as well as an alkali metal chlorite, the fibres then being treated in acidic solution at pH 3 to 6 to form the dyestuff on the fibre with simultaneous bleaching followed by conventional after treatments. The alkaline bath may contain a dispersant and/or wetting agent, the acid treatment preferably being at 50 to 90‹C.
