Caption: Woven wool fabric. Wool is the fiber derived from the fur of animals of the Caprinae family, principally sheep (hair of certain species of other mammals such as goats, alpacas, llamas and rabbits may also be called wool). Wool has two qualities that distinguish it from hair or fur: the cuticle or outer layer is scaly and is crimped (in some fleeces the wool fibers have more than 20 bends per inch). Beneath this is the cortex, the bulk of hair which contains hair pigments. At the center is the medulla, which may be hollow. Hair cells are dead except for a layer at the base of the root. Cells in this layer continue to divide forming new cells while pushing the older ones upward. Wool serves as a protection / insulation against harsh weather.
