[0002] Pad dyeing is a dyeing method in which the fabric is immersed in dye solution, and then the dye solution is penetrated into the fabric by the pressure of the roller and the excess dye solution is removed; in the prior art, the feeding device of pad dyeing generally adopts the method of padding for feeding, that is, the fabric needs to be immersed in the dye solution. Therefore, when the fabric is pad-dyed in the prior art, a large amount of dye solution needs to be prepared so that the fabric can be immersed in the dye solution, but this will bring a series of problems:

[0003] 1. Dye liquor contamination problem: Once the dyeing process begins, the dye liquor will continue to come into contact with the fabric, and the fabric itself may contain impurities or residues left over from the previous batch of dyeing. These factors will cause the quality of the dye liquor to gradually deteriorate, thus affecting the dyeing effect of subsequent fabrics, and may even lead to an increase in the rate of defective or scrapped products;

[0004] 2. Waste of dye solution: In order to meet the requirements of the padding method, a large amount of dye solution is usually required. However, in actual operation, it is difficult to ensure that all the dye solution can be completely consumed each time the padding is performed, which results in a large amount of unused dye solution being wasted, which not only increases the cost but also creates an unnecessary burden on the environment.

[0005] 3. Equipment cost and maintenance: In order to meet the demand for large bath ratio dyeing solution, dyeing equipment must have a larger capacity and volume, which not only increases the initial investment cost of the equipment, but also makes the daily operation and maintenance of the equipment more complicated and expensive;

[0006] Due to the above problems, the existing pad dyeing method feeding device has a large bath ratio, resulting in large water and material consumption, which in turn affects the dyeing quality of the fabric, increases production costs, and hinders the development of the enterprise.
