Wool is the fiber from the fleece of the sheep or lamb or hair of the Angora or Cashmere goat (and may include the so-called specialty fibers from the hair of the camel, alpaca, llama, and vicuna) which has never been reclaimed from any woven or felted wool product. Virgin wool and new wool are also used to refer to such never used wool.
Wool grades are selected to suit the needs of the products being made. Different wool grades offer different fiber lengths, fiber thicknesses and other properties. 1  Virgin Wool has two definitions. 2  First, it is the wool taken from a lamb's first shearing, which is the softest and finest sheepâs wool available.
