Wool is an animal fiber obtained from the fleece of sheep and other animals like goats. Major wool producing countries include Australia, New Zealand, China, and countries in Europe, Asia, and South America. Cashmere comes from the fine undercoat of cashmere goats and is made into expensive shawls. The production of wool involves rearing sheep, shearing their fleece, cleaning and processing the wool fibers, dyeing them, and making yarn.
