Anonymous users2024-01-23To put it simply, leather is made from animal skins that undergo a very complex physical (mechanical) processing and chemical treatment process. The difference in animal skins and the change in processing methods have led to a wide variety of leathers. Traditionally, the tanning process is generally divided into three stages:
Preparation, tanning and finishing.
1) In the preparation stage, its main purpose is to remove all useless things from the animal skin, such as hair, fat, various glands and soluble proteins in the skin, etc., and to treat the collagen fibers of the animal skin (that is, the main body that constitute the leather) to facilitate the subsequent processing and improve the quality of the leather.
The main processes at this stage are: water immersion, meat removal, hair removal, liming impregnation, degreasing, softening, and pickling.
2) In the tanning stage, its main purpose is to change the collagen fibers of animal skins in structure through chemical methods, so that they change from leather to leather. At the same time, it also determines the quality and performance of the resulting leather.
The main processes at this stage are: pre-tanning, main tanning and re-tanning.
3) In the finishing phase, the main aim is to enrich the special organoleptic properties of the leather, such as thickness, softness, color, surface condition and water resistance.
The main processes at this stage are: layering, shaving, neutralization, dyeing, fattening, drying, softening, flattening, grinding, finishing, embossing, etc.
