Treated animal leather

The skin is mainly peeled off from animals. After losing water, it will continue to harden after drying, and will not bend easily. It is very easy to break, and it will soften accordingly after encountering water. The animal skin after physical or chemical treatment will remove some useless components from the skin, and the chemical structure of collagen fibers in the skin is very easy to change, If the performance or state of our animal skin is fundamentally changed, the leather after drying can still be a raw material for leather making. Leather is mainly made from leather.
In our current life, we often get used to calling the leather made of real animal skin as leather, and the imitation artificial leather made of artificial synthesis as leather. Due to the continuous progress of equipment and materials, the manufacturing methods are also constantly updated. Among the various properties of artificial leather, it is a method very close to natural leather, and in many ways it surpasses natural leather, In many ways, it surpasses natural leather. Because artificial leather is basically difficult to distinguish natural leather and artificial leather from sensory aspects.
Recognition method of leather goods and artificial leather goods
1、 The appearance and texture are uniform without any natural disability, and there is no difference in grain thickness. It is likely to be artificial leather goods. The texture of natural leather is different, especially the main and secondary parts of leather goods, such as the front and back of shoes, the collar and back of leather clothes.
2、 Carefully observe the distribution and state of pores. The natural pores are deep and not easy to see the bottom, slightly inclined. Artificial leather pores are shallow, vertical and unnatural. They are stamped with equipment!
The pores of pig skin are in a group of three, and the pores are thick,
In terms of appearance, the texture of leather goods is relatively uniform without any natural disability, and there will be no difference in thickness in grain. In many cases, there is a great possibility that there are certain differences in the texture of artificial leather goods and natural leather, especially in the main or secondary parts of leather goods, such as shoes and leather clothes. In the second aspect, we can carefully observe the distribution and state of pores. The natural pores are deep and not easy to see the bottom, but also slightly inclined. The pores of artificial leather are relatively vertical and shallow, which is very unnatural. It is very inconvenient to stamp with equipment. The pores of pig skin are in groups of three, and they are thicker in terms of pores.
The first layer of cowhide accounts for one ninth of the whole cowhide in terms of grain leather and shaving leather of the first layer. Because it retains the natural attributes of cowhide, it has some original skin characteristics such as natural blood tendon marks and natural scars. It is very good in hand feel and texture, and very good in air permeability. Therefore, compared with other parts, it will be more precious. The surface quality of cow leather can be divided into two types, one of which is full grain leather. The main characteristic is to retain the natural grain surface of complete leather material, relatively clear, compact, small, plump and detailed surface, irregular arrangement and good and elastic air permeability in terms of pores. The other is smooth leather. Because there are differences on the surface, there are two kinds of leather: bright leather and fog leather, which belong to the category of shaved leather. In terms of fog surface, the cowhide surface is not shiny. And among them, bright leather is mainly used in the bright layer on a kind of leather surface with high brightness and excellent light transmittance. It is a popular aspect in many big brands.
