The invention relates to a high quality printing and dyeing mechanism of textile fabric, which comprises a dye box. A spray dyeing mechanism is arranged in the dye box, wherein the spray dyeing mechanism comprises a filter assembly, a grinding assembly arranged in the filter assembly and a spray dyeing assembly arranged on the filter assembly; the grinding assembly moves upward so that the filterassembly extracts the dye solution at the bottom of the dye box, and moves downward so that the filter assembly compresses the dye solution in the filter assembly and filters the dye solution. The filtered dye solution sprays out through the spray dyeing assembly. After the solution is sprayed and dyed, the grinding assembly continues to move downwards to grind the coarse particle dye remaining inthe filter assembly. A plurality of cloth guide rollers are arranged in the dye box, and the fabric is transmitted from the dye box from the bottom to the top under the guidance of the cloth guide rollers. The spray dyeing assembly comprises a duct a and a spray dyeing tube a and a spray dyeing tube b. The spray dyeing tube a and the spray dyeing tube b are respectively arranged on both sides ofthe fabric; the high quality printing and dyeing mechanism of textile fabric solves the problems of poor dyeing effect, uneven dyes, easy deposition of dyes at the bottom and staining impurities on the surface of fabric after dyeing.
