How to distinguish between good and bad cowhide

Dermal is made by peeling off the epidermis of animals and chemical treatment, while fake skin (mainly PU). PVC) is made of chemical fiber cloth. The difference between them lies in the different raw materials. However, due to the similar post-treatment methods, the surface effect is very close and it is difficult to distinguish, but there are many differences in internal physical properties.

There is still a certain gap (but the gap is narrowing step by step) in the physical strength, anti-aging and hand feel of leather. Genuine leather is expensive because its natural and intrinsic physical properties and raw materials are hard to obtain, while imitation leather has a market because of its price, surface effect changes and some special physical properties. In some industries that pay attention to intrinsic attributes, such as shoes and garments, genuine leather has advantages over imitation leather; However, in some industries that do not require intrinsic performance, such as leather handbags, furniture and sofas, the market for imitation leather is relatively large.

There are many leather shoes on the market at present. In order to reduce the cost, some genuine leather and some imitation leather are generally made together, or two layers of plastic film are used instead of genuine leather (PU is used as a mask on the second layer of leather, which has poor air permeability). It shouldn't matter if it's not used in the main part. If the shoes are completely genuine leather, it is normal to use a better one without damage in the main parts and a less damaged one in some secondary parts (such as the tongue of shoes) because of the naturalness of the leather. This is also a good way to distinguish genuine leather from fake leather products. After all, you can't cut other people's shoes to see if there is suede!

At the current market price, you can buy real leather shoes in most shoe stores in general cities above 150 yuan, but below this price, you are not in a regular shoe store. Be careful, especially those cheap goods sold by outdoor vendors. If you are not a professional (even a professional should be careful, an old engineer who has been doing leather for decades in our factory has been cheated), don't be greedy for petty gain. In a regular shoe store, you can buy a pair of leather shoes with trimmed leather around 150 yuan (that is, ground and heavily coated leather with poor air permeability), a pair of full-grain shoes around 300 yuan, and a pair of calfskin shoes around 300 yuan and above. Of course, if you want a higher grade, you can buy a pair of imported leather shoes. In this industry, the amount of artificial leather is relatively large, as follows:

1, women's fashion shoes. Almost all of them are imitation leather, and the better ones will make shoes with a little genuine leather.

2, sports shoes (travel shoes), almost using PU. PVC synthetic leather, coated with two layers is better, basically no top layer.

| 3, leather handbags, using double plastic film and fake leather mixed more.

4, belts, generally covered with two layers of film, imitation leather is easy to break.
