Including influence of the environment Animal biochemistry Natural dried skin and leather which comes from fresh skin has been used for many applications in the automotive sector, furniture, clothes and other industries.

Therefore, this study attempts to quantify and investigate the parameters o f fresh goat skin (Category I), natural dried skin (Category II) and leather (Category III), which also include orthotropic analysis (longitudinal and transverse directions). Uniaxial tensile test (ASTM D2099-00) was conducted to obtain engineering stress-stretch data for all categories.
