The story of wool began long ago, before recorded history when primitive man first clothed himself in the woolly skins, of the wild sheep he killed for food. He had discovered a durable fabric which gave him what nothing else could give: protection alike from heat and cold, from wind and rain. A versatile fabric which kept him cool in the heat of the day and warm in the cold of the night, which could absorb moisture without feeling wet.
Wool is a multifunctional fibre with a range of diameters that make it suitable for clothing, household fabrics and technical textiles.
Its ability to absorb and release moisture makes woollen garments comfortable as well as warm. Two thirds of wool is used in the manufacture of garments, including sweaters, dresses, coats, suits and "active sportswear". Blended with other natural or synthetic fibres, wool adds drape and crease resistance.
Slightly less than a third of wool goes into the manufacture of blankets anti-static and noise-absorbing carpets, and durable upholstery (wool's inherent resistance to flame and heat makes it one of the safest of all household textiles).
Industrial uses of wool include sheets of bonded coarse wool used for thermal and acoustic insulation in home construction, as well pads for soaking up oil spills.
The world's leading animal fibre, wool is produced in about 100 countries on half a million farms. Major producers are Australia, Argentina, China, India, the Islamic Republic of Iran, New Zealand, Russia, South Africa, United Kingdom and Uruguay. Depending on the country and region, wool producers range from small farmers (above, in Peru) to large scale commercial grazing operations.
The Rambouillet, related to the Merino, is the most common breed of sheep in the U.S., especially the western states where the majority of sheep in the U.S. can still be found. Fine wool sheep are best adapted to arid and semi-arid regions. They are known for their longevity and strong flocking instinct.
