Less-water dyeing process of polyester fabric

The invention relates to the field of polyester fabric dyeing processes, aims to solve the problems that in the prior art, a polyester fabric dyeing process is large in water consumption, and a large amount of waste water difficult to treat can be generated in the reduction cleaning process, and discloses a water-less dyeing process for polyester fabrics, which comprises the following steps: (a) mixing a disperse dye and a high-temperature leveling agent with water to obtain dye liquor, adjusting the pH of the dye liquor; (b) adding the polyester fabric into the dye liquor, and heating the dye liquor to start dyeing; (c) adding a polyester cleaning agent into the dye liquor after dyeing, adjusting the pH value of the dye liquor, heating, keeping the temperature for a period of time, and cooling; and (d) taking out the polyester fabric and drying. According to the present invention, the dyeing effect is good, the color fastness is high, the washing frequency is reduced, the water resource is saved, the wastewa
