    Abstract: Process for the dyeing of mixtures of cellulose, linear polyester and polyacrylonitrile fibers with reactive dyestuffs of the vinylsulfone type, disperse and cationic dyestuffs, wherein the goods are treated with a bath containing alkalies, non-ionic dispersing agents, a reactive dyestuff and a disperse dyestuff at 20* to 80*C and wherein subsequently free acid and a cationic dyestuff are added and the dyeing is completed in an acid medium at 95* to 130*C. Compared with the hitherto used two- or threebath processes the process of the invention has the particular advantage of saving 25 to 50 percent of dyeing time.
