The types of leather are different, and their characteristics and uses are also different. For example, cow leather has fine surface and high strength, which is most suitable for making leather shoes; sheep leather is light, thin and soft, and is an ideal fabric for leather garments; pig leather has good breathability and water vapor permeability.
Pig leather: The pores on the surface of the leather are round and thick, and extend into the leather obliquely. The pores are arranged in three groups, and the leather surface presents many small triangular patterns.
Cow leather: Both yellow cattle leather and buffalo leather are called cow leather, but there are certain differences between the two. The pores on the surface of the yellow cattle leather are round and straight into the leather. The pores are tight and even, and the arrangement is irregular, like a starry sky. The pores on the surface of buffalo leather are thicker than those of yellow cattle, the number of pores is less than that of yellow cattle leather, and the leather quality is slack. It is not as fine as the yellow water leather.
Horse leather: The hair on the surface of the leather is also oval, slightly larger than the pores of the yellow cattle leather, and arranged in a regular pattern.
Sheep leather: The pores of the leather grain are oblate, the pores are clear, and several pieces are grouped together and arranged in a fish scale.
