The concept of skin, leather, non-leather:

Leather: refers to the raw material that has not been tanned and has no direct use value. It is easy to understand that the skins of animals are such.

Leather: refers to the tanned skin, which can be directly used for making shoes, clothing, etc. Tanning is a thing we can not touch in life, a little mysterious, tanning methods are also divided into many kinds of different tanning methods finally formed leather types are also different, roughly divided into plant tanning leather, chrome tanning leather, oil tanning leather, brain tanning leather, aldehyde tanning leather, aluminum tanning leather, combined tanning leather and so on. Among them, plant tanning leather, chrome tanning leather, oil tanning leather is more common in leather goods, combined with tanning leather in the manual leather industry is also called semi-plant tanning.

Fei Fei Ge: To be honest, this name is not accurate, but it is understandable to say so. There are two main types, PU and PVC. Among them, PU is Poly Urethane, microfiber reinforced leather, PU is a kind of recycled leather (artificial leather), is the use of leather leftover materials reprocessed into industrial products, as we all know is regarded as garbage existence, whether it is brand luggage practitioners or manual leather goods industry, will deeply despise this kind of leather, But the author here to PU a slightly positive name, PU as a product of human wisdom and has remained until now, there must be its irreplaceable place, PU in its wear resistance, air permeability, feel, anti-aging, flexibility are normal, even more than some pure tanned leather such as sheepskin, sheepskin feel better, but other characteristics are not as good as PU, so, PU is commonly used in today's so-called "leather" seats.

How to tell the authenticity of leather:

1, the shape of natural leather is irregular, the thickness is not uniform, the surface is often more or less, or light or heavy there are some natural defects, the surface is smooth and fine, the general side belly slack, the whole material face leather has obvious pores and patterns, the leather is generally velvet. The synthetic leather has uniform thickness, smooth surface, no natural defects, its pores and patterns are also very uniform, and the leather is generally free of velvet.

2, for leather finished products, it is more difficult to distinguish between real and fake leather, especially small area, tight structure, can not see the leather products inside, the identification method of such products is: first look at the appearance, uniform texture, no disability, no coarse lines, no defects may be artificial leather; There are some differences in the texture of leather, especially the difference between the main part and the secondary part of the leather product should be obvious. Then carefully observe the pore distribution and shape; Natural leather holes and deep should not see the bottom, slightly inclined; The shallow and vertical pores may be synthetic leather modified leather. In addition, from the perspective of cross section, the cross section fiber of natural leather has its own characteristics, and the thickness of each layer of fiber changes. The fiber layers of synthetic leather are basically uniform, and the surface layer is like a plastic film.

3, dripping test: water absorption is obviously natural leather, and vice versa may be artificial leather.

4, tension and elasticity test: natural leather has good elasticity and tension, on the contrary is artificial leather.

5, blowing test: can be aligned with the reverse side of the leather with saliva blowing, in the front leakage, it is because the leather has this "anti-reverse performance", when you wear leather, the cold effect is very obvious, and formed a good permeability, which fully reflects the value of leather.

6, visual identification: First of all, it should be identified from the pattern of the leather, pores and other aspects, which can be seen on the surface of natural leather

To the pattern, pores do exist, and the distribution is not uniform, there are animal fibers on the back, side section, the level is obviously distinguishable, the lower layer has animal fibers, the fingernail scraping test will appear the leather fibers stand up, there is a feeling of velvet, a small amount of fibers can also fall down, and the synthetic leather can see the fabric on the back, there is no animal fibers on the side, the general skin has no pores, but some have imitation skin artificial pores, There will be non-obvious pores, some patterns are not obvious, or there are more regular artificial patterns, the pores are quite consistent.

7, feel identification method: Secondly, leather feel elastic, the front of the leather bending down about 90 degrees will appear natural wrinkles, bending different parts, the thickness of the fold, how much, there are obvious uneven, basically can be identified as leather, because the real leather has a natural uneven fiber tissue composition, so the formation of the fold pattern performance also has obvious uneven. Synthetic leather feels like plastic, poor resilience, bending down the thickness of the fold is similar.

8, odor identification method: natural leather has a very strong fur smell, even after treatment, the taste is more obvious, and artificial leather products, there is a plastic taste, no fur taste.

9, combustion identification method: mainly the smell of burnt odor and see the ash state, natural leather burning will emit a hair burnt smell, burnt ash is generally fragile into powder, and artificial leather, after burning the flame is also more prosperous, shrinkage rapidly, and there is a very unpleasant plastic taste, after burning sticky, after cooling will be hard into a block.
