Abstract

A method of dyeing polyamide textile materials comprises: (a) immersing the textile material in an aqueous dyebath containing a water-soluble anionic dye, the pH of the dyebath being maintained above 7 by the presence therein of an alkali metal phosphate; (b) raising the temperature of the dyebath to dyeing temperature, and (c) adding an acid to the dyebath to lower the pH thereof gradually to a level at which dyeing of the textile material takes place and continuing the addition and the dyeing until the dyebath is substantially exhausted. The method allows acid dyes to be applied, especially to nylon, at a high rate of dyeing giving level results.
