Natural leather than other materials, it is soft, breathable, abrasion, fold, beautiful... Therefore is necessary for high-grade leather shoes. Its features:
1 the natural leather parts quality difference is very big.
Due to the skin in animals, generating function area, also made the leather is different, each fiber structure, density, tensile strength and zhang is different. Especially impressions, feel is outspread, flexible and processing properties are different.
2 parts SiWen fibers (directional) structure.
Each different parts of leather, fiber orientation is different.
When gog, by tensile elongation of different parts.
Some stress is different, its elongation rate is different also, and the gap.
3 a permeability.
This feature enables the wielder wear shoes khan gas, to wear, make cavity user feel comfortable.
4 good heat resistance, cold resistance.
5 wear-resisting, stamping resistance, good performance and easy machining performance.
6 leather soft, elastic and tenacity and anti-bending of sex. Suitable for human physiological needs.
7. Beautiful and easy, modelling performance.
