Two Layers Of Cattle Hide Identification Technology

At present, the three most common types of leather on the market are leather, two layers of leather with PU/PVC coating, and artificial leather.

The most difficult to distinguish is the genuine leather and the two layer skin with PU coating.

The dermis is the raw skin that has been stripped from the animal. It is tanned and processed by tannery.

Generally it can be divided into two layers. Some animal skins are thicker and can even be divided into three layers and four layers.

In the order of the first layer, two layers of skin and three layers of skin, the quality grade is also good or bad.

The two layer skin fiber tissue layer is loose and poor in strength. Only when spraying chemical raw materials can it have the same appearance and better strength as the head skin.

Since two layers of leather are usually painted with PU or PVC, the two layer skin can only be defined as "half leather".

Identification techniques

The first layer of leather: the skin of the first layer is cut through the skin. After that, the animal's fibrous tissue can be seen, which is usually called "suede". According to the type of cattle, the age of the cattle and the thickness of the cut, the suede is different, but there must be suede.

Identification technique of top layer cowhide

Two layers of cowhide: as the chemical raw materials are sprayed, the color of the raw materials and the color of the skin will always have a certain chromatic aberration. This also provides convenience for us to identify.

Careful observation of the side, the two layer of leather coating part will have some small holes, the real leather will not appear this scene.

Identification techniques of two layers of cowhide

Through the identification of the above layer cowhide and two layers of cowhide, we can summarize some identification techniques: see if there is "suede", and the suede can be judged to be genuine leather or semi genuine leather; if there are layers in the cross section, there are two layers of leather and no layer skin.

In addition, some genuine leather sections will also appear partial "false stratification", the reason may be the leather polishing, the cow skin lacquer and so on the reason, uses the nail to attempt to scratch, vanishes, the false stratification is only partial, does not appear the entire pair of shoes cross section all has the stratification, if has the obvious stratification, that is the two layer skin, also is not the real leather.
