Abstract

Synthetic polyamide textile material is dyed with metal-free dyes by the exhaust method. The dyeing is started at a pH between 6 and 7 and completed at a pH between 3 and 6. In the course of the dyeing, the pH is lowered by at least one pH unit by the metered addition of an inorganic acid which has a pKa of below 3.8 at 20 DEG C. The exhausted dyebath is reused for dyeing after alkali and dye have been added. The process is environmentally friendly, since it produces less waste water than conventional processes. A further advantage is the absence of phosphate or borate from the waste waters and their low dye content.
