The invention discloses an active dye printing process which includes the steps of printing, drying, roll alkali treatment, steaming fixation, washing, soaping and washing. In the printing process, dyes in printing paste are divinyl sulfone active dyes or 'double-active-group active dyes comprising a vinyl sulfone active group and a chorotriazine active group'. In roll alkali treatment, mangle expression is 30-50%. Adopted fixation alkali liquor comprises 5-15% of sodium carbonate, 5-10% of sodium silicate, 0.5-2% of sodium hydroxide and the balance water. In the printing process, alkali agents and urea added into the printing paste can be omitted, roll alkali treatment and steaming fixation are performed after printing and drying, urea is omitted in the process, ammonia nitrogen emissioncan be greatly reduced, and sewage discharge can reach standards. Besides, dye hydrolysis can be reduced, the stability of the color paste is prolonged, steaming time is shortened, steaming efficiencyis improved, and product production cost is reduced.
