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.
Some people break out in red bumps and lumps when wool touches their skin. However, in many cases, a reaction to wool isn't due to allergies. Instead, direct skin contact with wool often causes irritation because of the slightly scratchy nature of some woolen clothing or because of chemicals in the fabric.ool is a natural fiber sheared from sheep and some goats. Once the wool is sheared from the animal, machines or human hands spin it into finer strands suitable for clothing and textiles. Wool sold in fabric stores comes in different grades. Fine grades, such as ultra-fine merino, tend to have softer, thinner fibers.
