A process for dyeing cellulosic containing textile materials with fiber reactive dyestuffs whereby from the scouring thru the after-scouring's final rinse less than 5 hours are required and only from 5 to 6 liquor baths are used. Material to be dyed is prepared for dyeing in 10 to 15 minutes at the boil, dyeing is performed in the next bath with no intermediate rinse. Glacial acetic acid, auxiliaries, and dyestuffs are added to the dye bath along with specified amounts of electrolyte, and after the required dyeing temperature is reached specified amounts of alkali are added to the dye bath and the materials subjected thereto at proper time-temperature relationships for level dyeing of a particular shade. Dyestuffs, electrolyte, and alkali are added to the dye bath in one portion with no dosing in a time period of from about 5 to 10 minutes each. The material is neutralized and soaped simultaneously.
