The so-called car leather is the raw hides that are peeled from animals and then processed by tanneries. Usually cowhide, sheepskin and pigskin are the main raw materials for making genuine leather. The dermis is generally divided into two types: the first layer and the second layer, and the quality, price and characteristics of the two are also different. Let us introduce the characteristics and difference between the two in detail for you.

1. The top layer of skin is the cow, sheep, and pig skin with grain surface. The skin surface has natural scars and blood veins, etc., and occasionally there are knife wounds in the processing process and the belly part with extremely low utilization rate. The top layer of leather also has the number brand of the cow. Full-grain leather can be distinguished from animal leather by the size and density of pores. There are many types of hides, such as cow hides, beef hides, pastured hides, cow hides, bull hides, uncastrated bull hides and castrated bull hides. In our country, there are also yellow cowhide, buffalo cowhide, yak cowhide and yak cowhide. Among them, the pores of buffalo leather are thicker and sparser; the pores of yellow leather are finer and denser than those of buffalo leather.

2. The two-layer skin is the loose two-layer part of the fibrous tissue, which is processed by spraying chemical materials or covering with PVC and PU films.

According to the different properties of the two, we can pull the dermis hard, the first layer of skin can see fine pores, and the surface of the skin will be deformed, while the second layer of skin has no pores and will not be significantly deformed; the second layer of skin is generally hard and feels very bad.
