The second layer cowhide leather also called split leather , also known as foil cowhide or composite cowhide, is also called artificial leather with cowhide fiber. It is not the skin of the cow, but the scrap of the real top layer and the real layer of skin is broken and then added with polyethylene material. It is made of a combination of chemically sprayed or coated with PVC or PU film on the surface. It still retains the characteristics of cowhide, but the durability and strength are not as good as the top layer of leather. After use, peeling and peeling will occur.

There was 5 ways below to distinguish top layer cow leather and split leather :

1)The first layer of skin is directly processed from the raw skin of various animals, or the skin of cattle, pigs, horses, etc., which are thicker in the skin layer, is cut into two upper and lower layers, and the upper part of the fiber structure is processed into various heads. Layer skin. The chopped skin is also the top layer of skin, which is the scrap in the whole top layer of cowhide. This material belongs to the manufacture of lowgrade leather products. After it is made, the skin texture will appear slightly different from the left and right thickness, but after all, it is the top layer of leather. There will be no peeling and peeling.

Distinguish between the first layer of skin and the second layer of skin, the internal touch feels, there is a sense of meat, the amateur can not touch it, the layman can use the hand to press, press the wrinkle is the top layer of skin, press the no wrinkles is the fake skin (ie the second layer of cowhide ).

2)Smell

The higher the grade of the top layer of cowhide, the thinner the skin, and the best top layer is as thin as paper.

The second layer of cowhide is the thickest, because the second layer of cowhide is broken with the first layer of leather and added with polyethylene material. If the leather surface is broken, it will be broken if it is not produced yet, so the leather surface is thick and the production process cannot be polished if it is polished. After the use, the upper will break, and the leather is easy to open without grinding. Therefore, the leather shoes of the second layer are made of machinery, no glue, no glue smell.

The leather shoes of the first layer of leather will be polished during the production, and the glue will make the glue more firm. If it is glued, it will naturally have a glue smell. The first layer of cowhide is the skin of the cow. The cow has only one color, and the gloss is not as bright as the second layer of cowhide (ie, fake cowhide). Therefore, after the production, the polishing agent will be sprayed, so there will be an oily smell.

3)Look at thickness

The first layer of skin is thinner than the second layer of skin. The thinner the top layer is, the thicker the second layer of cowhide. The reason is that the second layer of leather is broken after the top layer of leather is added, and the leather surface is broken. If it has not been produced, it will be broken, so the leather surface is thicker. The production process cannot be polished. If it is polished, the upper will break after use. The leather is easy to open without grinding. Therefore, the leather shoes of the second layer are made of machinery. No glue, no glue smell, the sole is made of foam and a small amount of rubber, and the sole will burst like tofu.

4)Look at the color

The top layer of cowhide should be divided into whole skin and broken skin. The leather color, back color and cross-section color of the whole skin are the same. Broken skin is also a kind of top layer skin, but for reasons of price, there are many colors. After production, a little color is sprayed. After use, some parts will have discoloration. Decolorization is not peeling. Decolorization can be re-sneeze and can be worn again. It can't be repaired and peeled off, and the price of broken skin is cheap, which is very popular among migrant workers.

The second layer of cowhide is a whole piece of leather, which will not discolor after use, but will peel off the skin, but the new time is good-looking, the appearance is graded, and it is very popular among white-collar workers.

5)Burn with fire,

Splitl leather cowhide (also known as artificial leather with cowhide fiber), also known as fake cowhide, also known as composite cowhide or film cowhide, because it uses the scrap of the top layer of skin, burned with fire, and has the same layer of cowhide. odor.

It is unscientific to use fire to distinguish true and false skins, because the second layer of cowhide can also be evenly fired, leaving no traces. If the merchants are coming to the fire, telling you that it is real cowhide, don't believe, this is the business to play. Barrier method.
