How to identify if it is dermis? How to tell if it s genuine leather

Pinch deeply with your fingernails, and the rapid rebound must be the dermis.

Here's my previous :Hope it helps you:

It's too difficult to tell if it's genuine leather. You're not a professional and don't want to mislead you. Even for me, after making the finished product, some materials have to be looked at for a long time and can't even be distinguished.

First of all, good genuine leather (such as full-grain calfskin, natural fall, grained nappa, etc.) they are only dyed and surface color repaired, without paint covers, and their textures are naturally formed, so there will always be small differences or even flaws in the local area (excluding the later scars of the finished product), if it is not professional, I am afraid it is difficult to see. The texture of artificial leather is pressed out, and its texture can be said to be perfect, and it is almost impossible to have flaws, otherwise it is a substandard product. "Ingenuity" is not actually "heavenly".

If you want to talk about the difference in feel and smell, artificial leather can be hidden from the world, and I don't have that confidence anyway. If you can confirm that it is dermis through the above methods, it must be dermis.

Secondly, if it is not a grain leather, but a heavier layer of paint skin, and even a layer of metal or plastic film is obviously on the surface, it is more difficult to identify, some of the first layer of leather because of surface defects or scars, after patching and embossing, the texture will be almost perfect, and some two layers of leather (cattle two layers) or pigs, cattle and sheep head layer after the film or film, there will be a layer of metal or plastic film on the surface, mainly to decorate and improve the utilization rate. These artificial leathers can do it, so it is difficult for non-professionals to tell whether it is genuine leather or not.

The easiest way to do this is to look at the reverse or cross-section of the leather. The cross-section of the leather is tight and not foamy, and the reverse fibers resemble the chicken silk after teeth picking (hehe, this metaphor is very disgusting) or sack silk, and some of the reverse fibers are not visible because they are pressed too hard, and they will appear when scraped with their fingernails, and the thickness of different types of leather is different. The fibers of artificial leather are like hair or no fibers.

Some shoes and bags, which have no edging and no edge oil, are easy to see the cross-section and bottom, which is easy to identify, and 99% are leather. The problem is that after the finished product is made, it is generally curled, which makes it difficult to identify.

That's all, I hope it helps.

Vision. 1. Look at the texture: The texture of the leather is uneven. The texture of the artificial leather is uniform.

2. Look at the bottom base: There is no bottom base on the reverse side of the leather. The faux leather has a cloth base on the reverse side.

3. Look at pores: The dermis has tiny pores. Faux leather has no pores.

4. Look at the section: The section of the leather is composed of irregular fibers, and there is no change in the upper and lower layers. The artificial cover can clearly see the different materials layer by layer.

Touch. 1. The leather is relatively smooth to the touch in a low temperature environment, and there is no cold feeling. Faux leather has a cold feeling to the touch in a low temperature environment.

2. It is better to stretch the elasticity of the leather to both sides by hand. Faux leather has no elasticity when pulled by hand.

Olfaction. 1. The smell of dermis is animal fat. Faux leather has a plastic smell.

2. After the leather is ignited, it will emit a hair smell and will not form pimples. Artificial leather will emit a pungent smell and pimple formation when ignited.

1.Method 1, from the sense of smell, the dermis smells of animal fat, and the imitation leather smells of plastic. 2.

Method 2, from the tactile sense, the real leather is relatively smooth and has no cold feeling in the low temperature environment, while the artificial leather has a cold feeling in the low temperature environment and is relatively stiff and jerky; Dermal skin has better elasticity, and there is a difference between transverse and longitudinal directions, while artificial leather is the opposite. 3.Method 3: From a visual point of view, the texture of the dermis is uneven while the artificial leather is particularly regular; The reverse side of genuine leather has no base and is plush, while the reverse side of artificial leather has a cloth base base; Genuine leather has tiny pores, while artificial leather does not; The cut surface of genuine leather is composed of irregular fibers and there is no change in the upper and lower layers, while the change of layer by layer can be seen in artificial leather.
