How to identify the authenticity of leather?
"Leather" is a common word in the leather product market, and it is a customary term for natural leather to distinguish synthetic leather; in consumers' minds, "leather" also has a non-fake meaning. In fact, real leather is leather, which is mainly processed from mammalian animal skins. There are many kinds of leather, with various varieties, different structures, different qualities, and great price differences. Therefore, leather is not only a collective term for all natural leathers, but also a vague mark on the commodity market.
How to identify the dermis
Hand touch: Touch the surface of the leather with your hands. If it feels smooth, soft, plump, and elastic, it is real leather; while the surface of general artificial synthetic leather is astringent, rigid, and poor in softness.
At first sight: the real leather surface has clearer pores and patterns, the yellow cowhide has relatively well-proportioned fine pores, the yak has thicker and sparse pores, and the goat skin has scaly pores.
Smell: All leather has the smell of leather; and artificial leather has a strong irritating plastic smell.
Ignite: Tear off a little fiber from the back of real leather and artificial leather. After lighting, it is artificial leather that emits a pungent odor and lumps; all that emits a hair odor without hard lumps is genuine leather.
With the above four basic identification methods, it is obvious to compare and identify artificial leather and synthetic leather. In addition, artificial leather and synthetic leather have the following characteristics:
1. Press the leather surface with your fingers, and there are no obvious pores and wrinkles. If there are wrinkles after pressing, they will not disappear naturally.
2. The leather surface has no pores, which is an important feature to distinguish genuine leather from fake.
3. Cut off the corners and burn, smelly, but not the burnt smell of hair.
Cow. Pig. Horse. Sheep leather
Different types of leather have different characteristics and uses. For example, cow leather has a fine surface and high strength, which is most suitable for making leather shoes; sheep leather is light, thin and soft, which is an ideal fabric for leather clothing; pig leather has good air permeability and water vapor permeability. Pig leather: The pores on the surface of the leather are round and thick, and they extend into the leather more obliquely. The pores are arranged in groups of three, and the leather surface presents many small triangle patterns
Cow leather: Yellow cattle leather and buffalo leather are both called cattle leather, but there are certain differences between the two. The pores on the surface of the scalpel leather are round and extend straight into the leather. The pores are tight and uniform, and the arrangement is irregular, like a sky full of stars. The pores on the surface of buffalo leather are larger than that of yellow cattle leather, and the number of pores is less than that of yellow cattle leather. The leather texture is looser, not as fine and plump as yellow cattle leather.
Horse leather: The hair on the leather surface is also oval, slightly larger than the scalper leather pores, and the arrangement is more regular.
Sheep leather: The pores of the leather grain are oblate, with clear pores. Several pieces form a group, arranged in fish scales.
