Genuine leather is made from animal skins, which is conceptually different from artificial leather made from chemical fiber materials.

How to identify:

Identify genuine leather

A handbag is no longer a bag in the ordinary sense. It is a symbol of character, profession, status, identity and taste. Compared with fashion, exquisite handbags have been popular for a longer time. This requires grasping the fashion trend when choosing. A carefully selected handbag has the finishing touch. It can decorate you into a real woman with elegant, fashionable and high taste. It can also reflect a person's identity, status, economic status and even personality, etc. For leather goods, how to identify genuine leather?

hand touch

That is, if you touch the leather surface with your hands, if it feels smooth, soft, plump, and elastic, it is genuine leather; while the general artificial synthetic leather surface is astringent, rigid, and has poor softness. Press the leather surface with your fingers. There will be no obvious pores and wrinkles. If there are wrinkles after pressing, they will not disappear naturally.

Seeing

Genuine leather has clearer pores and patterns, yellow cowhide has more symmetrical fine pores, yak leather has thicker and sparse pores, and goatskin has fish-scale pores. Whether there are pores on the leather surface is an important feature to identify the authenticity of leather.

sniff

All genuine leather has a leather smell; artificial leather has a pungent plastic smell.

ignite

Tear off a little fiber from the back of real leather and artificial leather, and after burning it, anything that emits a pungent smell and forms knots is artificial leather; anything that emits a hairy smell and does not form hard knots is real leather. There is a smell when the cut corners are burned, but it is not the smell of burnt hair.

Water absorption identification

The surface of genuine leather has better water absorption, while fake leather, on the contrary, has better water resistance. You can dip your fingers in some water and apply it on the surface of the clothing to observe its water absorption. If it has good water absorption, it is genuine leather. If it has poor water absorption or no water absorption at all, it is mostly fake leather.

Identify genuine leather vs synthetic leather

With the above four basic identification methods, we can compare and identify genuine leather and synthetic leather (artificial leather and synthetic leather refer to products with some characteristics of natural leather produced by different resin raw materials and various processing aids through different processing techniques. , some people call it artificial leather and simulated leather; artificial leather and synthetic leather have not yet been clearly and uniformly defined, so some people do not distinguish between them and collectively call them synthetic leather. The author believes that both names are relative to natural leather. , to the public, there is no difference between the two names). In addition, synthetic leather also has the following characteristics:

1) Press the leather surface with your fingers. There will be no obvious pores and wrinkles. If there are wrinkles after pressing, they will not disappear naturally.
2) The leather surface has no pores, which is an important feature for identifying the authenticity of leather.
3) If the corners are cut off and burned, there will be a smell, but it is not the smell of burnt hair.

The difference between the four types of leather

Different types of leather have different characteristics and uses. For example, cow leather is thin and strong and is most suitable for making leather shoes; sheep leather is light, thin and soft, making it an ideal fabric for leather clothing; pig leather has good breathability and water vapor permeability.

pig leather

The pores on the surface of pig leather are round and thick, and they extend into the leather at an angle. The pores are arranged in groups of three, and the leather surface shows many small triangular patterns.

Cow leather

Both cattle leather and buffalo leather are called cattle leather, but there are certain differences between the two. The pores on the surface of yellow cow leather are round and extend straight into the leather. The pores are dense and even, arranged irregularly, like a sky full of stars. The pores on the surface of buffalo leather are larger than that of cattle leather, and the number of pores is less than that of cattle leather. The leather quality is looser and not as delicate and plump as cattle leather.

horse leather

The hairs on the surface of horse leather are also oval-shaped, with slightly larger pores than ox leather and more regular arrangement.

Sheep leather

The pores on the grain of sheep leather are oblate and clear. Several pores form a group and are arranged in the shape of fish scales.

The difference between the four types of cortex

sheepskin

The pores on the surface of the leather are oblate and small, arranged in the shape of fish scales. Generally, several pores form a group. The leather is soft and very elastic.

Pigskin

The pores on the surface of pigskin are round and thick, and they penetrate deep into the leather at an angle. The pores are generally arranged in a group of three pores. The leather surface shows many small triangles. The elasticity is poor and the leather is thick.

cowhide

The surface pores of yellow cowhide are round, dense and uniform; the pores on the surface of buffalo leather are larger than those of yellow cowhide, but the number of pores is sparse and the texture is not as fine as that of yellow cowhide.

horsehide

The pores on the surface of horsehide are oblate and round, which is clearer than that of sheepskin. The leather is harder and the pores are arranged very regularly. Several pores are arranged in a group, and it feels rough and hard.

Daily care of leather

1. After the dermis is in contact with the outside world for a long time, moisture will be generated inside. It should be often placed in a ventilated place to dry to prevent the growth of bacteria. It can also be stored with an appropriate amount of moisture-proof beads.
2. If the genuine leather accidentally gets damp, use a dry cloth to absorb the moisture, and then place it in a ventilated and cool place to dry naturally. Do not expose it to the hot sun or dry it with a hair dryer to avoid explosion, deformation and hardening.
3. Genuine leather should not be placed in an environment where the temperature is too high, too low, or the humidity is too high, otherwise it is prone to wear and tear.
4. When cleaning the dermis, do not rinse with water or wipe with chemical reagents. Use cotton cloth and a soft brush to wipe.
