Some types of leather on the market are mainly divided into cow leather, pig leather and artificial leather, as well as suede for international brands.
The first kind: pigskin, which has the greatest strength, but has large pores, which is ugly and easy to identify
The second kind: cow hide, which is only inferior to pig skin in strength and has a fine surface, but is easy to be damaged
The third kind: artificial leather, which has a very fine surface, can be flawless, and is durable, but has some defects in air permeability and other aspects
Here are the specific distinguishing points:
Real leather refers to natural leather, which is processed from animal skins. Artificial leather refers to synthetic leather or other leather like products, which are actually artificially synthesized from basic chemical materials. The structure of natural leather is very complex, and it is extremely difficult, even impossible, to make it manually. Sometimes the artificial leather will also “confuse the real with the fake”, but my following method will make? You can learn to distinguish immediately!
- The shape of natural leather is irregular, and the thickness is uneven. The surface is often more or less, or light or heavy, with some natural defects. The surface is smooth and meticulous to varying degrees. Generally, the edges and abdomen are loose. Full grain leather has obvious pores and patterns, and the leather generally has pile. The synthetic leather has uniform thickness, smooth surface, no natural defects, even pores and patterns, and generally no pile in the leather.
- For finished leather products, it is difficult to distinguish between leather and artificial leather, especially leather products with small area, compact structure, and no visible inside. The method to distinguish such products is: first look at the appearance, with uniform texture, no damage, no coarse grain, and no defects may be artificial leather; There are some differences in the texture of leather, especially in the junction between the main parts and the secondary parts of leather products. The distribution and shape of pores were observed carefully; Natural leather has many holes and is not deep enough to see the bottom, which is slightly inclined; The shallow and vertical pores may be the synthetic leather modified upper leather. In addition, from the perspective of cross section, the cross section fiber of natural leather has its own characteristics, and the fiber thickness of each layer varies. The fiber layers of synthetic leather are basically uniform, with a layer of plastic film on the surface.
- Drip test: natural leather with strong water absorption may be used, while artificial leather may be used instead.
- Tension and elasticity test: natural leather has good elasticity and tension, and the reverse is artificial leather.
- Blowing test: You can aim at the back of the leather to blow with saliva, and leakage occurs on the front. It is precisely because the leather has this “anti reverse performance”. When you wear the leather, the cold proof effect is very obvious, and the good air permeability is formed, which fully reflects the value of the leather.
- Visual identification method: firstly, the pattern and pores of the leather should be identified. On the surface of natural leather, the pattern and pores really exist and are unevenly distributed. There are animal fibers on the reverse side, side section, and layers are clearly recognizable. There are animal fibers on the lower layer. Scratch with fingernails will cause the leather fibers to stand up and feel fluffy. A small amount of 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, there is no pore on the skin. However, some of them have faux skin pores, which may have inconspicuous pores, and some patterns are not obvious, or there are regular artificial patterns, and the pores are quite consistent.
- Hand feeling identification method: Secondly, the leather feels elastic. When the front of the leather is bent down for about 90 degrees, there will be natural wrinkles. When different parts are bent, the thickness and number of creases are obviously uneven. It can be basically determined that the leather is genuine leather. Because the leather has a naturally uneven fiber structure, the wrinkle lines formed are also obviously uneven. While synthetic leather feels like plastic, with poor recovery. The thickness of the crease is similar when it is bent.
- Odor identification method: natural leather has a strong fur smell, even after treatment, the smell is obvious, while artificial leather products have a plastic smell, no fur smell.
- Combustion identification method: It mainly refers to smelling burnt odor and looking at ash state. When natural leather burns, it will give out a smell of burnt hair. The burnt ash is generally fragile into powder, while artificial leather, after burning, has a strong flame, rapid shrinkage, and a very unpleasant plastic smell. It will become sticky after burning, and will become hard to block after cooling.
