advanced custom leather common sense | the difference between genuine leather and artificial leather

The standard answer under the old view is: genuine leather is natural leather, mostly from animals, with natural texture, strong air permeability and good resilience. Artificial leather is an industrial product similar to genuine leather made by coating PU resin on cloth. The appearance of artificial leather is stiff in texture, poor in air permeability, and obviously inferior in moisture absorption to genuine leather.
However, with the innovation of technology, artificial leather is getting closer and closer to genuine leather, and some luxury brands are also being used across the board. In order to design more creative patterns, genuine leather is also being pasted on the surface without seeing genuine leather pores and original leather lines. It is becoming more and more difficult to identify the true and false skin with the naked eye.
The specific differences are as follows:
1 The Concept
Leather: The so-called real leather is the original skin peeled from the animal and then processed by a leather factory. The dermis is generally divided into two categories: the first layer of skin and the second layer of skin (we will introduce how to distinguish between one layer and two layers in the next article).
Artificial leather: it is in the textile cloth base or non-woven fabric base, by a variety of different formulations of PVC and PU foam or film processing, can be made according to different strength and color, gloss, pattern and other requirements of processing.
2. Quality
The standard answer under the old point of view: the texture of the genuine leather is natural; The texture of the imitation leather is made by imitating the texture of the genuine leather during processing, so the texture of the genuine leather is more natural. Leather feel smooth and delicate, very texture; imitation leather will have a cold feeling, feel the roughness of industrial products is obvious.
In fact, the new genuine and fake leather does not have the above obvious feeling. recommend is a way of difference, which is to bend the leather properly to see the wrinkle texture and resilience of the leather. Generally, the resilience of the leather is better than that of the artificial leather. However, if the price of artificial leather bags has reached the price of genuine leather, it means that the artificial leather used by the brand has reached a very high level of simulation, so we don't have to care too much about whether it is genuine leather, after all, it is the brand value.
3. Price
Artificial leather is the impregnation, coating, solidification, washing, drying, surface finishing and other links of the base such as non-woven fabrics. The main differences of various artificial leather are shown in the fiber composition and structure used in the base of non-woven fabrics, as well as the types of polymers used in impregnated non-woven fabrics. Under mass production, most of the prices are relatively cheap. Of course, there are also fine-grained artificial leather, which is comparable to the price of genuine leather and is also used by individual luxury brands across the board.
Leather leather processing method is the animal skin processing mature leather for the production of leather products. Animal raw skin not only contains grease and wool fiber, but also becomes hard after drying. Therefore, in order to turn animal skin into leather that can be used by people, complex processes must be carried out first, and then tanning the bare skin with tannic acid. Tannic acid not only replaces the water in the raw skin, but also combines with the collagen fiber of the raw skin to become a leather with heat resistance, hydrolysis resistance and microbial resistance. Even if it is genuine leather, the price difference can range from a few yuan to thousands of yuan per square meter. The main difference lies in where the above process is carried out, whether the cycle of each process meets the standard, how many times, whether the liquid medicine is in compliance, etc. Generally speaking, if the indicators of the standard leather, the price is higher, so it is generally used for luxury high set bags, clothing.
