Leather is composed of natural protein fibers tightly woven in three-dimensional space. Its surface has a special grain layer with natural grain and luster, and it feels comfortable to the touch.

　　According to tanning methods, it is divided into chrome-tanned leather, vegetable-tanned leather, oil-tanned leather, aldehyde-tanned leather, and combination-tanned leather. In addition, it can be divided into light leather and heavy leather. Leather generally used for shoe uppers, clothing, and gloves is called light leather and is measured by area; leather made from thicker animal hides using vegetable tanning agents or combination tanning, used for the inner and outer soles of leather shoes and industrial accessories, is called heavy leather and is measured by weight.
