Wool

            
             Wool is the common name applied to soft, curly fibers gathered from the fleece of domesticated sheep, used in textile manufacturing. Wool may be distinguished from hair by looking at the scales that cover the fibers. Because it is curly and crimped, wool has considerable resilience or elasticity. Many reasons wool is used for clothing are because it is light and absorbs moisture, it also has insulating properties.
             Wild species of sheep have a short undercoat covered by long, coarse hair. The hair has entirely disappeared in domestic breeds; selective breeding has improved the abundance of wool. Many different things affect the influence of sheep production, like nutrition, climate, and the care of the sheep. Neglected domestic animals tend to grow hair instead of wool.
             Merino and Delaine merino sheep are the most common used for their wool. Other sheep are Cheviot, Southdown, Lincoln and Cotswold. For industrial purposes, the fiber of the camel, Angora goat, Kashmir goat, llama, alpaca, and vicuna is classed as wool.go.
             The sheep are sheared for their wool once every year, usually in the spring or early summer. In places with a warmer climate, shearing may occur twice a year. The fleece is cut close to the skin with shears and removed in one piece. .
             Wool from different parts of the sheep varies in length, fineness, and structure. Wool from the shoulders and sides is usually better than wool from the other parts of the body. Different breeds of sheep also produce different types of wool. Pure merino sheep bear the finest wool. About 40 percent of the world's total wool production is merino wool. 43 percent is from crossbred sheep.
             The first step in processing wool for cloth making is to sort the fibers. As each fleece is separated, the fibers are sorted by different characteristics, mainly fineness, length, and freedom from defects. After they are sorted, then the fibers are cleaned of yolk and perspiration.
