[0002] Animal leather is mainly composed of collagen fiber, and the fibers are tightly wound and combined together in a sheet shape by interstitial substance, fat and non-fiber protein. Currently, the use of animal skin is mainly to process into leather sheet to make leather shoes, clothing or leather products. This utilization method requires high-quality animal leather, which must have a certain size and uniform thickness. The utilization rate of animal leather is only 20-40%, and most of the leftover materials become waste. These leftover materials are usually prepared by crushing to form collagen fibers, crosslinked fibers, resins and other additives. The process flow is as follows: the leather or regenerated leather raw material is crushed into leather fibers of a certain size, then mixed with natural rubber, resin and other raw materials, and then compressed into filter cake. The filter cake is heated to melt the fibers on the surface and have adhesion. Each layer is extruded, bonded and dehydrated to form a final regenerated leather.
