description The invention belongs to the technical field of textile printing and dyeing and relates to a polyester cotton/viscose fabric dispersion/active pH control one-bath dyeing technique. The technique is characterized in that a pH high-low temperature control method is adopted; the dye bath pH value is high at low and medium temperatures so that the requirements of high-temperature active dyeing and fixation are satisfied, and staining, discoloration and color fastness problems caused by a dispersed dye in cotton group dyeing are controlled; at a high temperature after active fixation, naturalization and low alkali are realized through a high-temperature pH regulator; therefore, the conditions of dispersed high-temperature low-alkaline dyeing and hydrolysis caused by low activity are satisfied and contradictions and problems existing in two-dye dyeing are mediated and solved. The polyester cotton/viscose fabric dispersion/active pH control one-bath dyeing technique solves the bottleneck problem of the generic techn
