WOOL
Character of Fiber
Wool is the most important animal fiber. Strictly speaking the name applies only to the hairy covering of sheep, but the hair of certain goats and of camels is generally classified under the same terms. The wool fiber is distinguished by its scale-like surface which gives it its felting and spinning properties. Hair as distinguished from wool has little or no scaly structure being in general a smooth filament with no felting properties and spinning only with great difficulty. Fur is the undergrowth found on most fur-bearing animals and has in a modified way the scaly structure and felting properties of wool.
