TECHNICAL FIELD

[0001] The application relates to the field of fabric printing and dyeing, in particular to a knitted pile fabric printing and dyeing device. BACKGROUND

[0002] The knitted pile fabric is widely applied in the fields of clothes and home textiles due to its softness and comfort. In recent years, with the application of automatic technology and new materials, the printing and dyeing equipment gradually develops in the direction of intelligence and high efficiency. At present, the common knitted pile fabric printing and dyeing methods mainly include the immersion method, the spraying method and the padding method. The immersion method can achieve good dyeing effect by immersing the fabric in the dyeing solution, but the time consumption is long and the dye is seriously wasted. The spraying method sprays the dyeing solution to the surface of the fabric by using a high-pressure nozzle, which improves the production efficiency, but the dyeing solution is easy to accumulate when processing thick knitted pile fabric, resulting in uneven color. The padding method presses the dyeing solution by a roller, which is simple to operate, but has poor adaptability to the knitted pile fabric and is easy to cause damage to the fabric.

[0003] The existing knitted pile fabric printing and dyeing methods generally have problems of uneven dye penetration, low production efficiency and serious dye waste, which not only affects the quality of the final product, but also increases the production cost and affects the processing of the knitted pile fabric.
