Quickly distinguish between genuine and fake leather

Author: Released in:2021-04-13 Click:135

Real leather refers to natural leather, which is processed from animal skins. Artificial leather refers to synthetic leather or other leather-like products that are actually artificially synthesized from basic chemical raw materials. The structure of natural leather is very complicated. It is extremely difficult or even impossible under the current conditions to make it artificially and seamlessly.

  1. 1. The shape of natural leather is irregular, and the thickness is uneven. Its surface often has some natural defects in more or less, light or heavy. Because denim grows in nature, it is inevitable that there will be scars on the leather surface. The surface is smooth and meticulous, with obvious pores and patterns in the full-material surface leather, and there are generally piles in the leather. The synthetic leather has uniform thickness, smooth surface, no natural defects, uniform pores and patterns, and generally no lint in the leather.
  2. For finished leather products, it is difficult to distinguish between genuine leather and artificial leather, especially the leather products with small area, compact structure and invisible inside. The way to distinguish this kind of products is: first look at the appearance, uniform texture, no disability, There may be artificial leather without rough grains and defects; and the texture of the leather has some differences, especially the difference between the main part and the secondary part of the leather product. Then carefully observe the distribution and shape of the pores; natural leather has many pores and is not suitable for bottoming, and you can feel as if there are pores left by plucking hairs; and the pores with shallow vertical pores may be modified by synthetic leather. Some even directly use a machine to press out some similar pores, which can clearly be seen. In addition, from the cross-sectional view, the cross-sectional fiber of natural leather has its own characteristics, and the thickness of each layer of fiber varies. The fiber layers of synthetic leather are basically uniform, and the surface layer is in the shape of a plastic film.
  3. Tensile force and elasticity test: Natural leather has good elasticity and tensile force, otherwise it is artificial leather.
  4. Blowing test: You can blow with saliva on the reverse side of the leather, and there will be leakage on the front. It is precisely because the leather has this "anti-reverse performance" that when you wear leather, the cold-proof effect is very obvious, and it forms With good air permeability, this fully reflects the value of genuine leather.
  5. Visual identification method: First, it should be distinguished from the leather pattern, pores, etc., which can be seen on the surface of natural leather, The pattern and pores do exist, and they are unevenly distributed. There are animal fibers on the reverse side, the side section, the layers are clearly distinguishable, and the lower layer has animal fibers. If you try to scratch with your fingernails, the leather fibers will rise up, and there will be a velvety feeling. Fibers can also fall down, while the fabric can be seen on the reverse side of synthetic leather. There is no animal fiber on the side. Generally, the epidermis has no pores, but some have artificial leather and artificial pores. There will be inconspicuous pores, and some patterns are not obvious, or there are The more regular artificially made patterns, the pores are also quite consistent.
  6. Hand feeling identification method: Secondly, the leather feel is elastic. When the leather is bent down by 90 degrees, natural wrinkles will appear. When different parts are bent, the thickness and size of the wrinkles produced are obviously uneven, which is basically OK. It is believed that this is real leather, because real leather has a natural uneven fibrous structure, so the performance of the wrinkles formed is also obviously uneven. On the other hand, synthetic leather feels like plastic, with poor recovery, and the thickness of the folds are similar to each other.
  7. Burning identification method: mainly smelling the smell of burnt and looking at the status of ashes. When natural leather burns, it will emit a scorched smell. The burned ashes are generally fragile into powder, while artificial leather has a higher flame after burning. It shrinks rapidly and has an unpleasant plastic smell. It becomes sticky after being heated, and becomes hard and lumpy after cooling.
  8. However, due to the continuous innovation of the fashion industry in recent years, the leather material has been pressed into many new patterns, the most common one is the lychee pattern. Snake pattern, film patent leather, etc. It is not very obvious from the surface, but the authenticity can be identified from the side of the leather.
  9. Odor identification method: Natural leather has a strong fur smell, even after treatment, the smell is more obvious, while artificial leather products have the smell of plastic, without the smell of fur.
