description A process is described for the fast dyeing of textile materials constituted, at least to a significant degree, by polyamides, in particular quick dyeing polyamides, characterized in that a dye bath is employed comprising acid dyes to which a combination of reagents (e.g. ammonium sulphate and caustic soda) is added that is adapted to impart to the bath an initial alkaline pH and to lower the pH by elimination of volatile bases, at least at the final heating temperatures, and in that the bath is heated until final temperatures between 60 DEG C. and 80 DEG C. are attained.
