ABSTRACT:
A one bath dyeing process for dyeing cellulosic containing textile materials with fiber reactive dyestuffs, including polyester-cellulosic blends with disperse and fiber reactive dyestuffs. Material to be dyed is prepared for dyeing while avoiding residual chemicals that could retard dyeing. Dyestuffs and auxiliaries are added to the dye bath along with specified amounts of alkali and electrolyte and the materials subjected thereto at proper time-temperature relationships for level dyeing of a particular shade. Dye bath pH is maintained in a range of from about 8.0 to about 12.5 with total alkalinity being in a range of from about 1 to about 8 grams alkali per liter of dye bath. Electrolyte content in the dye bath is in a range of from about 50 to about 200 grams of electrolyte per liter of dye bath. For certain reactive dyestuffs, following the initial dye cycle, dye bath temperature is reduced, further alkali is added and a further short dye cycle is run to improve dye yield or wet fastness.
