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.
Longitudinal view of synthetic fibre and wool fibre. Woolâs unique cellular structure gives it a number of desirable properties. Most properties are typical of all wool, but there are some differences in wool from different sheep breeds.The differences affect the appearance and feel of the wool and what itâs used for.ool fibres have a unique surface structure of overlapping scales called cuticle cells. The cuticle cells anchor the fibre in the sheepâs skin. Woolâs surface is very different to typical synthetic fibres, which have a very smooth surface.
