PU leather is cheap. The price of leather is a bit more expensive than PU leather.
The dermis includes the first layer of leather and the second layer of leather; the first 4102 layer of leather includes grained leather, shaved leather, etc. 1653, among which the pores of natural leather can be clearly seen on the surface of the former, and the latter is either because of the pursuit of special effects or the surface of the embryo If it is severely damaged, it has to be done. After polishing, embossing, filming, etc., it doesn’t look very “natural”; I understand that the second layer of leather means that the leather is trimmed off the surface of the flesh and the artificial surface is applied, and then pressed again. The artificial surface layer does not look like natural leather. But they are all called "dermis".
PU leather is simply a layer of plastic products pressed on the base cloth, which is often referred to as "artificial leather".
Reshaping the face leather, because the second layer leather lacks the natural texture of the leather, if you do not look at the back and the cross section, it is sometimes difficult to distinguish it from the PU leather.
PU leather with good craftsmanship may be higher in price, appearance, and durability than the low-grade leather of reworked leather and two-layer leather. Therefore, price cannot be used as a criterion to distinguish real leather from not.

difference:
1. The leather surface is bright and smooth. The appearance is flat and soft, and the texture is plump and delicate. The texture is firm, firm and flexible when touched by hand. Smooth leather has good tensile strength, dirt resistance, abrasion resistance and good air permeability.
2. Synthetic leather (PVC and artificial leather (PU) are made of woven fabric or non-woven fabric. The exterior feel can be exactly like real leather, and they are respectively coated with polyurethane and made of special foam treatment. But breathability, wear resistance, Cold resistance is not as good as leather.

quality:
1. PU is polyurethane. Polyurethane leather has excellent performance. In foreign countries, due to the influence of the Animal Protection Association and the development of technology, the performance and application of polyurethane synthetic leather surpass that of natural leather. After adding superfine fibers, the toughness, air permeability and abrasion resistance of polyurethane have been further enhanced. There is no doubt that the performance of such manufactured products is quite excellent.
2. The best regenerated leather, the texture is very similar to the leather, and the feel is as soft as leather. It is difficult for outsiders to distinguish whether it is leather or regenerated leather. Microfiber leather belongs to a newly developed high-grade leather in synthetic leather, and belongs to a new type of leather. Because of its abrasion resistance, cold resistance, breathability, aging resistance, soft texture, environmental protection and beautiful appearance, it has become the most ideal choice to replace natural leather. The natural dermis is "woven" by many collagen fibers of varying thickness. There are two layers: a sub-grain surface layer and a mesh layer. The grain surface layer is woven from very fine collagen fibers, and the mesh is woven from thicker collagen fibers. Become.
