Technical Field

The invention relates to the technical field of leather processing, in particular to rolling type leather degreasing equipment.

Background

The physicochemical process by which the hide is converted into leather by a tanning agent is known as tanning. Tanning is an important process in leather and fur processing, and is the process of tanning agent molecule penetration into the skin and combination with collagen molecule active group of the hide to change the property. Tanning makes cross-linking bond between collagen polypeptide chains of the skin, increases the stability of a collagen structure, improves the contraction temperature and the stability of moisture and heat resistance, and improves the capacity of resisting acid, alkali, enzyme and other chemicals.

Before tanning leather, the leather needs to be degreased, and the tanning quality is poor due to incomplete degreasing; the most original degreasing mode is to extrude fat in the middle of the skin by mechanical force, which is rarely changed into saponification washing by alkali liquor or dissolution by solvent, but the method can only remove grease on the surface of the skin, and lipid substances in the skin, including sebaceous glands and the like, are difficult to remove, thus affecting the quality of subsequent tanning.
