1. Visual identification method: First of all, it should be distinguished from the leather pattern and pores. On the surface of natural leather, it can be seen that the patterns and pores do exist, and they are unevenly distributed. There are animal fibers on the reverse side, and the side section is clearly distinguishable. There are animal fibers in the lower layer. The leather fibers will stand up when you try to scratch with your fingernails. A small amount of fibers can also fall down. The fabric can be seen on the reverse side of the synthetic leather. There is no animal fibers on the side. Generally, the epidermis has no pores. , But some have artificial leather pores, there will be inconspicuous pores, some patterns are not obvious, or there are more regular artificial patterns, and the pores are quite consistent.
2. Hand feel identification method: Secondly, the leather feel is elastic. When the leather front is bent down by 90 degrees, natural wrinkles will appear, and different parts will be bent. The thickness and size of the wrinkles produced are obviously uneven. It is believed that this is real leather, because real leather has a natural uneven fibrous structure, so the formation of wrinkles is also obviously uneven. On the other hand, synthetic leather feels like plastic, with poor recovery, and the thickness of the folds on bending is similar.
3. Smell 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.
4. Combustion identification method: mainly smell the smell of burnt and look at the status of ashes. When natural leather is burned, it will emit a scorched smell. The ashes burned are generally fragile into powder, while artificial leather has a higher flame after burning. Prosperous, shrinks quickly, and has an unpleasant plastic smell. It becomes sticky after being heated, and becomes hard and lumpy after cooling.
