Hunting hide: it is characterized by well-developed subcutaneous fat. Hunting hair is a group of three, which is shaped like a shape. It grows deeper and runs through the whole dermis. The hair roots are most concentrated in a fat cone. After being made into shoes, the grain surface is rough and the smoothness is not as good as that of cowhide. Secondly, the fiber bundles of poaching leather are relatively thick and strong, interwoven and dense. Therefore, it has greater strength and wear resistance The braiding form varies with the position of the leather, so the position difference is large.

Cattle hide and cattle hide: it is characterized by small pores, fine grain size, thin surface and high tensile strength; the thickness of each part is uniform and the difference is small, so the utilization rate is high, and the fibrous tissue of buttock is tight; the fibrous tissue of abdomen and shoulder is loose; the armpit is more soft and thin, but the occupation ratio is small.

Buffalo hide: it is characterized by long and thick hair, loose fibrous tissue, large part difference, and Tabanus eye or Tabanus bottom on the back. Compared with cattle hide, the fiber is thinner and slightly soft, second only to cattle hide.

Sheepskin and sheepskin: it is characterized by dense sheepskin, thin epidermis, low tensile strength and high elongation; due to its high fat content, it has good warmth retention and soft and comfortable leather.

Goatskin: similar in appearance to coarse wool sheepskin, smooth and fine grain. Fiber bundle weaving is more compact than sheepskin. The results showed that the fiber bundles were thick, the leather was soft and extensible, the thickness of neck and abdomen was different, and the sheepskin was more folding resistant.

Miscellaneous skin and horse skin: the tightness of each part is different, and the horse thigh is particularly hard, with less water permeability and air permeability.

Deer skin: it refers to the skin of domestic deer, wild deer and muntjac. It is characterized by softness, large porosity, sufficient toughness and high extensibility.

All natural leathers are extensible, breathable and absorbent.
