The Chinese patent with publication number CN116397402A discloses a high-end textile fabric printing and dyeing device, including: two supporting legs, a pad dyeing mechanism and an automatic cleaning mechanism. When the present invention is printing and dyeing fabrics, the lifting group drives the pressing shaft and the squeeze roller to move upward, so that the squeeze roller squeezes the fabric and squeezes out the air bubbles in the textile fibers of the fabric, so that the dye liquid can penetrate into the fabric. It makes the fabric printing and dyeing more complete and uniform, improves the quality and efficiency of fabric printing and dyeing, and during the fabric printing and dyeing process, the cleaning group and the material removal group are used to clean the surfaces of the support roller, pad dyeing roller, and squeeze roller that support the fabric. Cleaning: After the fabric is printed and dyed, the inner wall of the printing and dyeing barrel is cleaned through the automatic cleaning mechanism to prevent the dye residue adhered to the equipment from adhering to the printed and dyed fabric again due to insufficient cleanliness of the printing and dyeing equipment, affecting the uniformity and uniformity of fabric printing and dyeing. Printing and dyeing quality.
