wool wiki:
>This article is about wool, the fibre produced from sheep. For alternative meanings see Wool (disambiguation). Wool is the fibre derived from the hair of animals of the Caprinae family, principally sheep and goats, but the hair of other mammals such as alpacas may also be called wool. This article deals with the wool produced from domestic sheep. Wool is the fibre produced as the outer coat of sheep. Most of the fibre from domestic sheep has two qualities that distinguish it from hair or fur: it has scales which overlap like shingles on a roof and it is crimped; in some fleeces the wool fibres have more than 20 bends per inch.
