There are many kinds of leather commonly used, divided by type, can be divided into: dermis, microfiber skin. Green skin, cipri, imitation leather. 1. Dermis: The dermis is made from animal skins and is conceptually compared to artificial leather made of artificial fiber. In the market, the dermis is generally one of the three types of scalp, two-layered leather, and synthetic leather. The prices of the three kinds of skin are successively decreasing. The identification of the dermis is mainly 4 points Seeing Real leather surface has clearer pores and patterns, yellow leather has relatively well-proportioned fine pores, yak skin has coarse and sparse pores, and goat skin has scaly pores. There are no pores on the leather surface, which is an important feature to identify the true and false leather. Sniffing All leather has an odor of leather; artificial leather has a strong irritating plastic smell. ignite From the back of real leather and artificial leather, tear off a bit of fiber. When it is ignited, it gives a pungent odor. The result is a leatherette. Any hair that smells irritated and hardens is leather. Cut corners burning, odor, but non-hair char smell. Water identification The surface of the dermis has good water absorption, whereas the false skin, on the other hand, has better water resistance. Fingers can be used to pick up some water, wipe on the surface of clothing, observe its water absorption, such as good water absorption, for the dermis, poor water absorption or no water absorption, the majority of false skin. 2. Microfiber leather: Microfiber leather is called "microfiber reinforced leather." It has extremely excellent abrasion resistance, excellent breathability, aging resistance, softness, comfort, strong flexibility, and environmental protection that is now advocated. Microfiber leather is the best regenerated skin, softer than leather, and super-fiber leather. It belongs to a newly developed high-grade leather in synthetic leather and belongs to a new type of leather material. Because of its advantages of wear resistance, cold resistance, breathability, aging resistance, soft texture, environmental protection and beautiful appearance, it has become the ideal choice for replacing natural leather. Practice has proved that the excellent properties of the microfiber leather can not be replaced by natural leather. From the analysis of domestic and foreign markets, microfiber leather has also largely replaced the natural leather with insufficient resources. The use of ultra-fiber leather as a decoration for bags, clothing, shoes, vehicles and furniture has been increasingly recognized by the market. Its wide range of applications, large quantities and many varieties are beyond the reach of traditional natural leather. 3. Green skin: The skin is commonly called artificial leather. Green skin and real appearance are more similar. The feel of the microfiber leather is similar to that of the dermis. The biggest difference between artificial leather and genuine leather is that the natural pores of the leather can dissipate heat and air, but the artificial leather does not. For example, some people who wear artificial leather shoes will get beriberi and leather shoes will not wear leather because it has natural pores. This kind of skin is cheap, but it has poor air permeability. In the summer, it is easy to form sweat on the back and buttocks; easy to fade easily. 4. Cipi: also known as imitation leather, is a synthetic leather, artificial leather, surface coating, smooth and beautiful, feel good, compared with the surface of leather is difficult to distinguish. Sub-import imitation leather, domestic imitation leather. However, the quality of Cipi has a great difference. The poor quality of Xipi is not as good as the quality of PU and environmental protection leather. The quality is good and the quality of microfiber leather is similar. Some high-grade xipi can even be used in aviation seats. "Synthetic synthetic leather that resembles a leather pattern such as "rhinohide". 5. Imitation leather: Imitation leather is made of synthetic material. It is not afraid of blemishes. It is not easy to mold and has good surface water resistance. However, synthetic leather is not resistant to high temperatures and is not resistant to chemical attack. Imitation leather PU and PVC are many. PU leather: PU is polyurethane, which is divided into polyether type and polyfluorene type. PU leather refers to an artificial leather product coated with PU. It is characterized by the softest texture, folding resistance, and certain hygroscopicity. PVC leather; the first generation of PVC artificial leather, based on textile or knitted materials. Polyurethane resin is a coated leather imitation product with characteristics similar to natural leather, bright appearance, soft texture, abrasion resistance, folding resistance, and acid and alkali resistance.
