Wool Fiber:
Wool is an animal hair fiber that, chemically, is made of a naturally occurring protein called keratin. This is a general definition that would include the body hairs of many animals but, in common parlance, the word is used for the body hair of sheep. This animal natural fiber comes from sheep fleece. The chemical structure is constituted by the keratin, a complex organic substance formed by amino acids. Its section is round, its structure is scaly.
