Abstract

For dyeing textiles, dyes, in particular reactive or vat dyes, of varying solubility are used. A process is now presented in which, in a first process step, the suspension comprising coloured pigments, dispersion aids, reducing agents, polar solvents, such as water, alcohols, surfactants, alkalis and/or acids is stirred and, in a second process step, the agglomerates of the coloured pigments are comminuted by means of ultrasound and the dye solution is subsequently or simultaneously drawn off. An apparatus for carrying out this process comprises a mixing vessel (16) and at least one reactor (1) with ultrasonic generators (6), a return line (30) to the mixing vessel (16) being provided. The process and the apparatus have the great advantage that a high colour yield is achieved and less environmental pollution is produced. <IMAGE>
