For genuine leather, **1500 or so, the original price is 3000+
Natural leather is processed from animal skin, which has a very special fiber structure and excellent air permeability and water vapor permeability. In recent years, with the progress of production technology, the appearance of synthetic leather is very similar to that of natural leather, coupled with the large number of applications of film transfer leather, which makes it difficult to distinguish between natural leather and synthetic leather.
The shape of natural leather is irregular, and the thickness is not very uniform. Due to the reason of animal raw leather, natural leather has some disabilities more or less, light or heavy, including insect wounds, fly wounds, lice wounds, abrasion scratches, etc., and its surface smoothness and fineness, fiber tightness, and thickness will be different. For example, the back is tightly fibrous, while the side area (abdomen) is more relaxed.
The front leather has clear pores and patterns, and there are fat lines and blood tendons in some parts. Leather cross-sectional fibers have their own unique characteristics, and the thickness of the fibers in each layer varies greatly. In terms of appearance, the surface of synthetic leather is very homogeneous, the texture is very uniform, and the surface layer is composed of a polyurethane layer with a microporous structure.
The pores and patterns pressed on the surface are also consistent. The synthetic leather fibers are very homogeneous, and some synthetic leather does not have a fiber structure. In addition, natural leather and synthetic leather can be distinguished according to different flavors according to the fire test, generally synthetic leather with the burning smell of plastic (synthetic material), and natural leather with the smell of burnt hair.

The color of the leather incision is basically the same as that of the leather, the dyeing is uniform, the leather has no cracks and no cracks, and the suede fluff is evenly rented.
2) Physical and chemical properties.
There are six physical and chemical performance indicators:
1) Tearing force: 11 N for sheep leather, 13 N for pig, cow, horse and mule leather, 9 N for cut leather and other small animal skins.
2) Specified load elongation: 25 60.
3) Rubbing color fastness: dry rub 3 4 grade (smooth leather), wet rub grade 3 (smooth leather); Dry wipe 3 levels (suede), wet wipe 2 3 levels (suede).
4) Shrinkage temperature 90C. 5) The pH value is: 6) pH dilution difference.
The main physical performance indicators of clothing leather are tear force and color fastness to friction, and if any of the two is unqualified, the whole leather will be unqualified.
