How to distinguish between genuine leather and fake leather of safety shoes

For safety shoes, how to distinguish between genuine leather and fake leather, this small series to tell you how to identify genuine leather and fake leather! Let’s be smart consumers

1. The shape of natural leather is irregular, and the thickness is uneven. 1ts surface is often more or less, or light or heavy, with some natural defects. 1ts surface is smooth and the degree of fineness is different. Generally, the edge and abdomen are loose. The whole material leather has obvious pores and patterns, and there are pile in the leather. The synthetic leather has uniform thickness, smooth surface, no natural defects, uniform pores and patterns, and no pile in the leather2. For leather products, it is difficult to distinguish between real and fake leather, especially for leather products with small area, compact structure and invisible inside. The identification methods for such products are as follows: first, look at the appearance, and the leather products with uniform texture, no damage, no coarse grain and no defect may be artificial leather; There are some differences in the texture of leather, especially in the joint between the main part and the secondary part of leather products. The distribution and shape of pores were observed carefully; The natural leather has many deep holes, which is not suitable for bottoming and slightly inclined; However, the leather with vertical pores may be the synthetic leather. 1n addition, from the view 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 plastic film on the surface

3. Dripping test: the natural leather with strong water absorption is obvious, otherwise it may be artificial leather< 4. Tension and elasticity test: natural leather has good elasticity and tension, otherwise it is artificial leather 5. Air blowing test: it can be aimed at the reverse side of the leather with saliva, and there is leakage on the front side. 1t is precisely because of the “anti reverse performance” of the leather that when you put on the leather, the cold proof effect is very obvious, and a good air permeability is formed, which fully reflects the value of the real leather 6. Visual identification method: first of all, we should identify the patterns and pores of the leather. On the surface of natural leather, we can see that the patterns and pores do exist and are unevenly distributed. There are animal fibers on the reverse side, side section, and obvious layers. There are animal fibers on the lower layer. Scratching with fingernails will cause the leather fibers to stand up and feel fluffy, A small amount of fiber 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, and generally there is no pores on the epidermis. However, some have imitation leather artificial pores, and there are not obvious pores, some patterns are not obvious, or there are more regular artificial patterns, and the pores are quite consistent 7. Handle identification method: secondly, the handle of genuine leather is elastic. Natural wrinkles will appear when the leather front is bent down about 90 degrees. The thickness and amount of creases produced by bending different parts are obviously uneven. 1t can be basically identified as genuine leather, because the genuine leather has natural uneven fiber structure, Therefore, the wrinkle lines formed are obviously uneven. Synthetic leather feels like plastic and has poor recovery. When it is bent down, the crease thickness is similar 8. Odor identification method: natural leather has a strong smell of fur, even after treatment, the taste is obvious, while artificial leather products have a smell of plastic, no smell of fur 9. Combustion identification method: it is mainly used to smell scorched odor and see the ash state. When natural leather burns, it will emit a smell of scorched hair. The burned ash is generally fragile into powder, while artificial leather has a strong flame after burning, shrinks rapidly, and has a very bad plastic smell. 1t will stick after burning, and harden into blocks after cooling copyright notice: This article is reproduced from the network media, only represents the author’s point of view, and has nothing to do with this website. 1f the information column articles and comments violate your legal rights, please call to let us know and we will deal with them in time
