Abstract
Abstract A dyeing process for the production of multi-colour effects on natural and synthetic polyamide fibre material, as well as the multi-coloured fibre material produced thereby, which process consists of pretreating the fibre material with an aqueous solution of at least one colourless, fibre-reactive compound and optionally with one levelling agent having affinity for the fibre material, combining the treated material with untreated fibre material and/or with at least one fibre material pretreated in a different manner, and dyeing the combined fibre material with a dyestuff having affinity for the fibre material or with a mixture of such dyestuffs, said process being characterized in that the colourless, fibre-reactive compound contains per molecule thereof at least one group of the Formula I
