True leather refers to natural leather and is made of animal skins. Fake leather refers to synthetic leather or other dermis. It is actually a synthetic product of basic chemicals. The structure of natural leather is very complicated. It is extremely difficult or even impossible to make it artificially seamless. Sometimes fake leather can be "realistic", by the following methods can distinguish true and false leather:
1, the shape of natural leather is irregular, the thickness is not uniform, the surface is often more or less, or light or heavy, there are some natural defects, the surface smooth and meticulous degree is different, the general side of the abdomen is loose, all the material The leather has obvious pores and patterns, and leather usually has piles. The thickness of the synthetic leather is uniform, the surface is smooth, there is no natural defect, and the pores and patterns are also uniform. In the leather, there is generally no pile.
2. For finished leather products, it is difficult to distinguish between genuine leather and fake leather, especially leather products with small area, tight structure and no visible inside. The method of distinguishing such products is: first look at the appearance, uniform texture, no disability, No rough lines, no defects may be artificial leather; and leather texture has some differences, especially leather products, the difference between the main site and the minor site should be more obvious. Then carefully observe the distribution of pores and their shapes; natural leather holes are many and deep and not suitable for bottoming, slightly inclined; while the pores are shallow and vertical may be synthetic leather modified surface leather. In addition, from the cross-section, the cross-section fibers of natural leather have their own characteristics, and the thickness of each layer of fiber has changed. The layers of synthetic leather are basically uniform and the surface layer is plastic film.
3, drip test: the obvious water absorption is natural leather, and vice versa may be artificial leather.
4. Tensile strength and elasticity test: natural leather has good elasticity and pulling force, and vice versa is artificial leather.
5. Blowing test: The reverse side of the leather can be blown with saliva, and leakage occurs in the front. It is precisely because the leather has this “anti-reverse performanceâ€. When you put on the leather, the cold-proof effect is very obvious. Very good breathability, which fully reflects the value of leather.
6, visual identification method: First of all, should be identified from the leather pattern, pores and other aspects, in the surface of natural leather can see patterns, pores do exist, and the distribution is uneven, the opposite side of animal fibers, side section, the level is clearly visible There are animal fibers on the lower layer. When the fingernails are used for scratching, the leather fibers will rise up and there will be a nappy feeling. A small amount of fibers can also fall down. The synthetic leather can see the fabric on the reverse side and there is no animal fiber on the side. Generally, the skin is not pored. However, some have artificial leather pores, there will be no obvious pores, some patterns are not obvious, or there are more regular artificial patterns, the pores are quite consistent.
7, feel identification method: followed by a rich leather feel elastic, the leather will bend down about 90 degrees will appear natural wrinkles, respectively, bending different parts, resulting in folds thickness, how much, there is obvious uneven, basically can It is believed that this is a genuine leather because natural leather has a natural non-uniform fibrous structure, and thus the formation of wrinkle lines is also markedly uneven. The synthetic leather feels like a plastic, the recovery is poor, and the folds are similar in size.
8, odor identification method: natural leather has a very strong smell of fur, even after treatment, the taste is more obvious, and artificial leather products, there is a share of plastic taste, no fur taste.
9, burning identification method: mainly smell the smell of coke and see the state of ash, natural leather burning will emit a burning smell of hair, fired ash is generally easy to break into a powder, and artificial leather, flame after burning Prosperous, it shrinks rapidly, and it has an unpleasant taste of plastic. It sticks when burned, and it hardens into a block after cooling.
