Decrypt! True and false and type of leather and leather materials

There are many types of leather on the market. From leather to artificial leather PU leather, from grain surface to water ripple cross lines, people are unable to choose.

Many people have a high degree of doubt about leather clothes.

Let’s unveil the leather leather!

First of all, the leather is mainly divided into two categories: leather and artificial leather.

The leather refers to the processing of the skin of animals. At present, the market is more used in sheepskin, cowhide, pork skin, and some special leather, such as fish skin, snake skin, crocodile skin, lizard skin, etc.

There are three main types of artificial leather, namely artificial leather, synthetic leather (PU), and super fiber leather.

Genuine Leather

The leather can be divided into facial leather and repair leather. The grain leather is processed by the superior raw material skin with less disability. It retains the natural state of the leather and the thin coating can show the natural pattern of animal skin. The repair leather is generally repaired by flawed skin. For example, imitation crocodile patterns, lizard patterns, ostrich leather patterns, python leather patterns, water wave patterns, beautiful tree patterns, lychee patterns, and imitation deer patterns.



The pores of the sheepskin are flat and the pores are clear. Several forms are formed, and they are arranged into fish scale. According to the source of sheepskin, it can be divided into goatskin and sheepskin.


Sheepskin fiber tissue is relatively solid and soft and elastic. Similar to the yellow leather, but thinner, the skin surface is clear, the surface of the surface is fine, and the leather feeling is strong. The sheepskin is similar to that of goatskin. Because the fat glands and sweat glands of the beam are more, it is particularly soft after making the finished product. You can only do leather clothing and gloves.


Cowhide is the most commonly used leather in leather. According to the type, it can be divided into orange leather and cowhide. According to the production process, it can be divided into vegetable tanned and chromium tanned. Tan tanning is an important process for tanning and fur processing. With extension, different tanning leather uses different tannasters to produce different tannasus. Among them, vegetable tanned leather is a leather that is processed by natural plant tannasus; it is not dyed to obtain primary color leather, and the so -called high -quality vegetable tanned leather is also used.

Cowhide can generally be sliced ​​into multiple layers, which is the head layer of the head layer and the second layer of skin. The thick cowhide can be made up to five layers.

The head layer is the first layer of the leather. The pores of the head layer are small, round, uniform and tightly distributed, bright and smooth in the leather surface, full of texture, delicate appearance, flat and soft appearance, and the touch texture with the hand is solid and elastic. The second layer of cowhide is the remaining part of the layer with a smooth skin, which has the characteristics of good strength, elasticity and process plasticity. The second layer of leather is only a loose fiber tissue layer. It can only be used to make leather products after spraying chemical raw materials or polishing. It maintains a certain characteristics of natural elasticity and process plasticity, but the intensity is poor.

Pork skin

Because pig hair passes through the cortex to the straight meat layer, the permeability and humidity of pig skin are better than cowhide, but the pores are large, the finished fonts, rough leather patterns, not as beautiful as cowhide, but they are strong and durable. Because the pores of the pigskin are very large, the breathability is outstanding, and it can also absorb sweat. Therefore, pig skin is often used in the inside, which is very soft and comfortable.


artificial leather

Artificial leather (imitation leather), which is made of bubbles or coating of various formulas on textile cloth or non -woven bases.


Artificial leather

Synthetic Leather

Super fiber leather

Coating leather

Stem synthesis leather

Ultra -fine fiber synthetic leather


Extended leather

Wet Method Synthetic Revolution


Semi -PU leather


Artificial Revolution: Painted or fit a mixture composed of PVC, plasticizer, stabilizer, etc., coat or fit a simulatory leather plastic product synthesis leather: use PU (polyurethane resin), auxiliary agent, filler, etc. mixture. A super -fiber synthesis leather obtained by coating or fit on a base cloth: It is processed by the beam ultra -fine fiber and polyurethane through special process. It has ultra -fine fibers similar to the structure and performance of natural leather beam -like glue fibers. Non -woven fabric manufacturing non -woven fabrics with a three -dimensional network structure.

Leather quality identification

1. About observation

The pores on the surface of sheepskin are flat and round, with small pores, and arranged into fish scale. Generally, several pores are composed of a group. The leather is soft and elastic. The pores on the surface of the pig skin and pig skin are thick and large, and they are tilted into the leather. The pores are generally arranged in three pores. The leather surface presents many small triangles (character -shaped). The elasticity is poor and the leather is thick. The epidermal pores of cowhide scareh leather are round, with tight pores and evenly. The pores on the surface of the water leather are larger than that of the yellow cowhide, but the number of pores is scarce, and the texture is not as delicate as the yellow cowhide.
