A process for the dyeing of textile material containing amino or amide groups, especially polyamide such as nylon is disclosed which comprises dyeing said material in a homogeneous solution of one or several water-soluble reactive dyestuffs, in a mixture of a chlorinated aliphatic hydrocarbon, especially trichloroethylene or perchloroethylene, with up to 50 percent of a hydrophilic solvent, especially N,N-dimethylformamide, during about 30 to 50 minutes at a dyeing temperature of about 40* to 130*C. The thus obtained dyeings have excellent fastness properties and the procedure is characterised in shortening the dyeing time compared with the conventional dyeing process. |
