What is the two layer of skin:

The two layer of skin is the two layer of fibrous tissue is loose， the chemical material spraying or PVC， PU film processing overlying a. The two layer of skin tissue only loose layer， only in the spraying chemical raw materials or polishing can be used to make leather products， it maintainsthe certain characteristics of the natural elasticity and plasticity of theprocess， the thickness of the first layer of skin as the same.

The difference between the first layer of skin and the two layer of leather，Pu leather:

The first layer leather is the animal fur， leather and leather with scaranimal natural crease. Hands down， there is a wrinkle， also have naturalleather wrinkles. A long time will not break.

Two layer leather is leather scrap after breaking up， adding polyethylenematerial re bonding leather， and then by chemical material spraying or PVC， PU film processing overlying a. Leather two layers of skin， handsdown， is no wrinkles， use long， there is no natural leather wrinkles， will occur if cracks， serious to fracture. The two layer of skin still maintain theleather characteristics， but the durability and folding strength is not as good as the first layer of leather.

Pu is polyurethane ingredients skin， thermoplastic elastomer， elasticity，abrasion resistance of this kind of material is good， is a kind of plastic， it is widely used。
