First of all we all know, that is to see the face or back, the back of the leather and the back of the leather is completely different, this is the vast majority of people the most direct way to judge. Leather is a natural fiber structure, imitation leather on the combination of polyurethane and yarn products friends, a look you know Luo. Of course, there is a kind of PU transfer film, that is, the use of cowhide pieces pressed into a thin piece of cowhide block, and then coated with a layer of leather on it, from the back is indecipherable, because the back is Cowhide structure, that is just crushed cowhide pressed into, but the front is faux leather, so only see the back of the leather fiber, you can not jump to make a decision Oh, but also through the following several ways to double confirmation. (Now mixed leather on the market a lot of crushed leather Oh, it gives you a back view of cowhide, guests do not understand the facts, the cheaper price and the back of the figure to be blinded, in fact, it is immeasurably leather Because it can only count the imitation leather Oh, parents have to be careful not to buy it by mistake) Method One: Leather bags in the fold or under pressure will have subtle "wrinkles" just like human skin , Hand pressure will have natural wrinkles, cowhide such wrinkles similar to people's wrinkles, I remember it was oppressed and folded up only Oh, some artificial leather is also able to emboss these folds Oh . Method two: a simple identification is to use nails to pinch, of course, do not pinch it, and gently pinch down, if you can quickly bounce back, that is, Pipporo, can not bounce back or rebound very slow may be fake leather Well, because one of the characteristics of leather is elasticity. Method three: It is judged by the temperature, leather is animal skin, it is a constant temperature, the winter will not be cold, Imitation of the skin is obviously cold 啦, if you have a leather bag and a leather bag to the winter effect Suddenly came out. Method Four: just said that leather is animal fur, so a little smelly leather taste, leather are tanned from chemical substances, chemical smell and a touch of animal odor, which is how the leather can not be removed You can smell it carefully. The faux leather only smell or chemical odor, chemical odor is very pungent. Method five: If it is difficult to argue through the above several, then no way, then cut off a small fry with a lighter to burn, if issued by the smell of burning trotters, then congratulations, bought a real leather. Sixth: There is another is that we often say that the leather can be severely opened, you can see the leather pores, which is a way, but I am myopic, it is estimated that the face can not see it. So I do not apply.
