Explanation

The animal skins stripped from slaughtered animals are the objects of leather making or fur production, including cow skins, pig skins, sheep skins, horse skins, donkey skins, fish skins, kangaroo skins, ostrich skins and crocodile skins. Mammalian skin generally consists of the epidermis, corium layer and subcutaneous tissue layer. Remove the subcutaneous tissue layer, retain the coat of the epidermal layer, and obtain fur after tanning. If the epidermis (including the fur coat) is also removed and tanning, the product is leather. In essence, leather and fur are the combination products of collagen fiber and tannin in raw corium layer.
