ABSTRACT:
A process for dyeing a voluminous flat form anionic dyeable substrate, for example a carpet, comprises applying locally to said substrate one or more dyes, optical brightening agents and/or reserving agents having low migration properties followed by pre-fixation of the same, subsequently dyeing the treated substrate in a short bath with one or more dyestuffs having better migration properties, rolling up the substrate and rotating the rolled-up substrate under conditions to effect fixation of the dyestuffs.
