Actually, genuine leather is leather, which is mainly processed from mammalian skin. There are many types of genuine leather, with various varieties, different structures, different qualities, and widely varying prices. Therefore, genuine leather is not only a general term for all natural leather, but also an ambiguous label in the commodity market. According to their types, natural leather mainly includes pig leather, cow leather, sheep leather, horse leather, donkey leather and kangaroo leather, etc., and there are also a small amount of fish leather, reptile leather, amphibian leather, ostrich leather, etc. Among them, cow leather is divided into cattle leather, buffalo leather, yak leather and yak leather; sheep leather is divided into sheep leather and goat leather. According to its layers, there are first-layer leather and second-layer leather. The first-layer leather includes full-grain leather and trimmed leather; the second-layer leather includes pig second-layer leather and cow second-layer leather. Among the main types of leather, cattle leather and sheep leather have a flat and fine surface, small pores, fine and tight inner structure, good fullness and elasticity, and good physical properties. Therefore, high-quality cattle leather and sheep leather are generally used as leather materials for high-end products, and their prices are higher among bulk leathers. Among the many leather varieties, full-grain leather should be at the top of the list because it is processed from the finest raw material leather with less damage. The leather surface retains its natural state and has a thin coating, which can show the appearance of animal skin. Beautiful natural patterns. It is not only wear-resistant but also has good breathability. Shaved leather is made by using a leather grinder to lightly grind the leather surface, then paint it, and then press it with a corresponding pattern. In fact, it is a "facelift" to the damaged or rough natural leather surface. This kind of leather has almost lost its original surface condition, has a thicker coating layer, and has worse wear resistance and breathability than full-grain leather. Split-layer leather is made by splitting thick leather with a skin machine. The first layer is used to make full-grain leather or trimmed leather. The second layer is made into split-layer leather through a series of processes such as painting or laminating. Its fastness, It has poor wear resistance and is the cheapest leather of its kind. 1. Feel: if you touch the leather surface with your hands, if it feels smooth, soft, plump and elastic, it is genuine leather; while the surface of general artificial synthetic leather is astringent, rigid and has poor softness. 2. Visual inspection: Observe that the real leather surface has clearer pores and patterns. Yellow cowhide has more symmetrical fine pores, yak skin has thicker and sparse pores, goatskin has fish-scale pores, and pigskin has triangular thick pores. As for artificial leather, although the pores are also imitated, they are not clear. Characteristics and identification methods of pig leather, horse leather, cow leather, and sheep leather: cow leather is fine in surface and high in strength, and is most suitable for making leather shoes; sheep leather is light, thin and soft, and is an ideal fabric for leather clothing; pig leather is breathable and water vapor permeable It has good performance and is more suitable for making underwear and children's products; the fiber structure of horse leather is relatively tight and the strength is relatively high, so it is better used for making leather pants and leather boots. Generally speaking, the thickness, density and distribution of pores on the leather surface are the main basis for distinguishing cow leather, pig leather, horse leather and sheep leather. Pig leather: The pores on the leather surface are round and large, extending into the leather at an angle. The pores are arranged in groups of three, and the leather surface shows many small triangular patterns. Cow leather: Both cattle leather and buffalo leather are called cow leather, but there are certain differences between the two. The pores on the surface of yellow cow leather are round and extend straight into the leather. The pores are dense and even, and the arrangement is irregular, like stars in the sky. The pores on the surface of buffalo leather are larger than that of cattle leather, and the number of pores is less than that of cattle leather. The leather quality is looser and not as delicate and plump as cattle leather. Horse leather: The pores on the leather surface are oval, slightly larger than the pores of ox leather, and arranged more regularly. Sheep leather: The pores on the leather grain are oblate and clear. Several pores form a group and are arranged in the shape of fish scales. 3. Smell: All real leather has the smell of leather; while artificial leather has a pungent plastic smell. 4. Ignite: Tear off a little fiber from the back of real leather and artificial leather. After igniting, anything that emits a pungent smell and forms knots is artificial leather; anything that emits a hairy smell and does not form hard knots is real leather.
