How to distinguish various leather materials

①Cowhide:
A. According to cattle species: yellow leather and buffalo leather. The pores of yellow cowhide are different from those of buffalo cowhide. The pores of buffalo cowhide are thick, and the individual pores are sparsely arranged, and the neck lines are many and rough. The pores of yellow cowhide are dense, and several pores are arranged in series, with raised lines between the series pores. Under the light, it is easy to see these intertwined 'skin patterns'.
B. According to the size of the cow: there are fetal cowhide, calf cowhide, middle cowhide and large cowhide, which can be distinguished from the width of the cow and the thickness of the skin pattern. The fetal cowhide and calf cowhide have fine and dense skin patterns, and medium cowhide and large cowhide. Cowhide skin texture is coarse and loose.
C. According to the cortical layer: there are first layer skin, shaved skin, and second layer skin. The first layer of skin, that is, the undamaged skin of the animal's original skin; the trimming of the skin, which is to polish the damaged leather on the surface of the skin, remove the original texture and disability, and then press the artificial skin texture; the second layer of skin , As the name suggests, is the second layer of animal skin. There is no cortex layer, but a fiber layer. The tensile strength, toughness and folding resistance are poor, so it is not suitable for shoe fabrics.


②Recognition of sheepskin:
Sheepskin fiber is very fine, very soft, dense pores, soft and soft, but the disadvantage is that the texture is easy to wrinkle and the strength is low.


③Identification of pigskin:
Pigskin is harder and has no elasticity. The pores are thick and arranged in triangles. The texture is thick and suitable for lining.


④ Identification of flower skin:

There are hundreds of kinds, such as snake pattern leather, tiger pattern, crocodile pattern, straight pattern, net pattern, litchi pattern, imitation ostrich leather, twill pattern, opening pattern, etc., named after various patterns on the surface of the cowhide .



⑤Frosted leather:
Polish the leather surface to abrade the grain scars or rough fibers to expose a neat and uniform leather fiber structure.


⑥Rare animal skins:
The original skins of wild or artificially bred animals are characterized by scarce quantity, special ornamental properties, and good formability. Such as: crocodile skin, lizard skin, snake skin, ostrich skin, deer skin, kangaroo skin, shark skin, eel skin, etc.





One smell, two look, three touch

As soon as it smells, any leather must be soaked in liquid medicine before it can be used. Therefore, leather products have an unpleasant smell. Similar to ink. But the fake ones are gone. Because it is chemical, there is no unpleasant smell. Made. The taste of leather is obviously gluey.

Secondly, the texture of the dermis is very irregular. It gives a very real feeling.
The fake one cannot achieve the unique natural texture of the dermis, so it is forced to add wrinkles. Generally, it looks fake.

Three touches, the dermis is a naturally formed thing. There are pores on it. These pores are like snake skin, with a sense of order.
It feels a bit rough when you touch it. Leather products don't have these tiny holes. It feels extremely smooth.

But some leather products are synthetic.
It is made of leather and real leather. Now most of the belts are similar to this thing.
