Polyester fabric disperse dye dyeing mildew removal process

The invention discloses a polyester fabric disperse dye dyeing, mildew removal and reduction cleaning process, which adopts a low-alkali scouring agent TF-1291K to realize low-temperature mildew removal, omits a mildew removal step before dyeing, and directly completes high-quality dyeing and high-efficiency mildew removal through one bath and two steps. Tests prove that the low-alkali scouring agent TF-1291K can keep an excellent H2O2 decomposition catalyzing effect at the low temperature of 80-90 DEG C, HO2 is obtained through catalytic decomposition, a color development system of mildew is destroyed under the condition that the pH is larger than or equal to 10, and the mildew on the polyester fabric is effectively removed. On one hand, the washing treatment at the temperature of 80-90 DEG C belongs to low-temperature treatment in the field, so that the colored light is not influenced, and the dyed fabric obtains stable colored light and excellent washing fastness. And on the other hand, the low-alkali
