Abstract
A process for dyeing textile materials of naturally occurring and synthetic polyamide fibres, in which dyeing is carried out at the boiling point of the dyebath during a short dyeing time which is therefore gentle on the fibres, and level dyeings having good fastness properties are obtained (high temperature rapid dyeing process). The dyeing process is carried out with dyebaths with comprise specific surfactants. A high degree of exhaustion of the dye liquors is achieved, and dyeing from static baths is thus rendered possible.
