True and false leather discrimination skills

"Leather" is a common word in the leather product market. It is a customary name for natural leather for the purpose of distinguishing between synthetic leather and 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 type, 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 materials 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, and then applying a 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 condition, the coating layer is thicker, and its wear resistance and air permeability are worse than that of full grain leather. The two-layer leather is a split-skin machine made of split leather, the top layer is used to make full-grain leather or shaved leather, and the second layer is made into a second-layer leather through a series of processes such as painting or filming. Its fastness, Less wear resistance is the cheapest kind of leather in its class. However, different types of leather have similarities in appearance and internal structure, such as horse leather and cow leather, yellow cattle leather and yak leather, donkey leather and sheep leather, kangaroo leather and calf leather, and the like. With the improvement of leather processing technology, leather can be modified and imitated embossed, making it completely different, some of the original features are covered, and then cut and finely sewed, what kind of leather it has, with the naked eye Hardly recognizable. Therefore, the fakes behind the leather were given a heaven-sent opportunity. For the pursuit of profit, very few manufacturers use the similarities in the appearance of different leathers, and steal or replace them in the production process. For example, the leather is filled with leather, the cow hide is filled with yellow leather, and the donkey skin is used to infuse sheepskin. In the business, but also common leather products hanging on the "leather" or "cowhide" logo, individual sales staff to sell their own goods, do not make detailed introductions, resulting in customers mistakenly choose to purchase. Leather is almost a household name and well known to everybody. However, there is a lot of lack of relevant knowledge. The methods described above are more professional. Here are some of the more commonly used methods: 1. Touch: Touch the leather surface with your hands. If it is smooth, soft, plump, and elastic, it feels like genuine leather; 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. Third, odor: Any real leather has the smell of leather; and artificial leather has a strong irritating plastic smell. Fourth, light: From the back of real leather and artificial leather to tear off a bit of fiber, ignited, where a pungent odor, entanglements is artificial leather; Any hair that emits odor, does not result in hard leather is leather.
