[0002] Leather is a denatured and non-perishable animal skin obtained through physical and chemical processes such as depilation and tanning. Leather is made of natural protein fibers tightly woven in three-dimensional space. Its surface has a special grain layer with natural grain and luster, and feels comfortable. When leather is made into various other products, it needs to be processed by dyeing. Leather dyeing is a very complex physical and chemical process, which is the penetration and combination process of dye molecules on leather fibers, and is the total effect of physical and chemical effects.

[0003] The existing authorization announcement number is CN 208667756 U, and the patent name is "A spiral hide dyeing drum for high-performance green leather manufacturing".
