Different types of leather have different characteristics and uses. For example, cowhide has a delicate surface and high strength, which is most suitable for making leather shoes; Sheep leather is light and soft, which is an ideal fabric for making leather clothes. Pigskin has good air permeability and moisture permeability. The specific identification method is as follows:

1. Pig skin: The pores on the skin surface are round and thick, and extend obliquely into the skin. The pores are arranged in groups of three, and the leather presents many small triangular patterns.

2. Cowhide: Cowhide and buffalo hide are both called cowhide, but there are some differences between them. The pores on the surface of cowhide are round and extend straight into the leather. Pores are compact and even, and arranged irregularly, like stars all over the sky. The pores on the surface of buffalo hide are thicker than those in cattle hide, the number of pores is less than that in cattle hide, and the leather is loose, which is not as detailed and plump as yellow buffalo leather.

3. Horse skin: The hair on the leather surface is also oval, slightly larger than the pores of cowhide, and the arrangement is relatively regular.

4, sheepskin: the pores on the surface of the dermatoglyphic are flat and round, and the pores are clear. They form a group of several, arranged in fish scales.

Daily care of dermis:

1. After long-term contact with the outside world, moisture will be generated inside the dermis. In order to prevent the growth of bacteria, it should always be dried in a ventilated place, or an appropriate amount of moisture-proof beads can be put in for preservation.

2. If the genuine leather gets wet carelessly, it should be dried with a dry cloth, and then placed in a ventilated and cool place, and naturally dried in a cool place. It should not be placed in the scorching sun or put in a hair dryer to dry, so as to avoid explosion, deformation and hardening.

3. Don't put the leather in an environment with too high temperature, too low temperature and too high humidity, otherwise it will be easy to wear.

4. Leather cleaning should not be washed with water or wiped with chemical reagents, but should be wiped with cotton cloth and soft brush.
