Problems solved by technology

[0005] Although there is a relatively mature technology for dyeing leather, for fur leather, due to its special structure composed of two parts, the coat and the leather plate, it is more difficult to process, especially in terms of dyeing effect. It is difficult to balance the multi-faceted requirements of color and feel. When the quilt and the leather board are of the same color, the above problems are not easy to solve. When there is a color difference between the wool quilt and the leather board, especially when the color difference is large
At present, after the dyeing treatment is carried out on the fur leather raw materials, the skin surface of the dyed leather is usually prone to whitening and poor plumpness in the subsequent grinding process
