"Leather" is a common word in the leather product market. It is a customary term for natural leather for the purpose of distinguishing between synthetic leather; in the consumer's mind, "dermis" also has a non-fake meaning. In fact, the dermis is leather and it is mainly made of mammalian skins.

There are many types of leather, various types of products, different structures, different quality, and a wide range of prices. Therefore, the leather is not only the collective name of all natural leather, but also a vague sign on the commodity market.

Natural leather is divided into pig leather, cow leather, sheep leather, horse leather, donkey leather, and kangaroo leather according to its kind, and a small amount of fish leather, reptile leather, amphibious animal leather, ostrich leather and the like. The cow leather is divided into yellow cattle leather, buffalo leather, yak leather and yak leather; sheep leather is divided into sheep leather and goat leather. According to its hierarchy, there is a first layer of leather and a second layer of leather, in which the first layer of leather has full grain leather and shaved leather; the second layer of leather has a second layer of pig leather and second layer of cattle leather. Among the main types of leather, yellow cattle leather and sheep leather have a fine surface, small eyes, and compact internal structure. The leather body has good plumpness and elasticity, and has good physical properties. Therefore, fine yellow cattle leather and sheep leather are generally used as leather materials for high-grade products, and the price is higher in the bulk leather.

Among all kinds of leather products, full grain leather should top the list, because it is made from the finest raw material with less disabilities. The leather surface is preserved in its natural state. The coating is thin and can show the animal skin. The natural beauty of the pattern. It is not only wear-resistant but also has good air permeability.

The face leather is made by grinding the surface of the leather with a buffing machine, followed by painting and pressing the corresponding pattern. It is actually a "facelift" of a natural leather surface with disability or roughness. This type of leather almost loses its original surface state, the coating layer is thick, and the abrasion resistance and air permeability are worse than that of full grain leather.

The two-layer leather is a split-skin machine made from a split-skin machine. The first layer is used to make a full-grain leather or a facelift. The second-layer leather is made into a second-layer leather through a series of processes such as painting or pasting. Its fastness, Less wear resistance is the cheapest kind of leather in its class.

Here we introduce several common methods:

First, feel: that is, touch the leather surface by hand, if there is a smooth, soft, plump, elastic feeling is the leather; and the general artificial leather surface is astringent, rigid, poor flexibility.

Second, seeing: Observe the real leather surface with clearer pores, patterns, yellow leather has a more well-proportioned fine pores, yak skin has thicker and sparse pores, goat skin has scaly pores, pigskin has triangular coarse pores, The artificial leather, although it also imitates the pores, is not clear. Here we introduce the characteristics and identification methods of pig leather, horse leather, cow leather, and sheep leather. The cow has a fine leather surface and high strength. It is most suitable for making leather shoes. Sheep leather is light, thin and soft and is ideal for leather garments; pig leather. The air permeability and vapor permeability is good, and it is more suitable for making underwear and children's products. The leather structure of horse leather is tight and the strength is relatively high. It is better for making leather pants and leather boots. In general, the thickness, density and distribution of the pores on the surface of the leather are the main basis for distinguishing cow leather, pig leather, horse leather and sheep leather.

Pig leather: The pores on the surface of the leather are round and thick and extend into the leather more obliquely. Pores are arranged in groups of three, and the leather surface presents many small triangles.

Cow leather: Both cattle leather and buffalo leather are called cattle leather, but there are also certain differences between the two. The pores on the surface of the yellow cattle leather are round and extend straight into the leather. The pores are tight and even, and the arrangement is irregular, which seems to be starry. Buffalo leather surface pores are thicker than the yellow cattle leather, the number of pores is less than the yellow cattle leather, leather is loose, not as full and delicate as the cattle. Horse leather: The pores on the surface of the leather are oval-shaped, slightly larger than the pores of the cattle leather, and the arrangement is more regular.

Leather: The pores of the leather grain are oblate, and the pores are clear. Several roots form a group and are arranged like a fish scale.

Third, odor: Any real leather has the smell of leather; and artificial leather has a strong irritating plastic smell.

IV. Ignite: From the back of real leather and artificial leather, tear off a bit of fiber. When it is ignited, the pungent odor that causes pungency is artificial leather. Any hair that emits an odor that does not form a hard coat is the dermis.
