What is Wool?
Wool is the fleece of a sheep. It is a very versatile fiber. When knit or woven into a fabric, wool is warm and dense, creating the perfect, durable, cold weather garment. Wool is flame resistant and can prevent outside moisture from reaching the skin of the wearer by pulling the liquid directly into the core of the fiber leaving the surface relatively dry. Wool can absorb up to 1/3 of its own weight in liquid before feeling wet. Compare that to synthetic fibers that can only absorb 2 or 3%.
Because wool can retain moisture so well, it also prevents static electricity.
Wool resists noise by absorbing the sound waves.
As you may have noticedperhaps by accidentwool felts. Felting happens when wool is exposed to hot water and agitated, tossed and beat around in the warmth causing the individual fibers to interlock to create a dense mass of fiber.
