WOOL:
Wool, common name applied to the soft, curly fibres obtained chiefly
from the fleece of domesticated sheep, and used extensively in
textile manufacturing. The fleece of sheep raised for wool is
generally shorn once yearly, in the spring or early summer. In
regions where the climate is warm throughout the year, shearing
may occur twice annually. The fleece is cut close to the skin,
usually with mechanical shears, and removed in one piece.
The value of wool on the market depends primarily on fineness
and length of fibre. Strength, elasticity, amount of crimp, and
uniformity are also considered. Two different systems are followed
in wool processing, the woolen system and the worsted system.
In the woolen system, the fibres are carded and then spun. In
the worsted system, the fibres proceed to a combing process, which
separates the long from the short fibres. Before the wool can
be used for commercial purposes it must be scoured or cleaned.
Scouring & cleaning may be done using warm water, detergent,
alkali & carbonization.
Wool is used in clothing, shirting, suiting, woolen sweaters,
blankets, upholsteries, felt, horse rug, carpets, insulation.,
