Sheep wool is a natural fiber obtained from the fleece of sheep. It is composed mainly of a protein called keratin, which gives it strength and elasticity. Wool is known for its insulating properties, making it warm in winter and cool in summer. It is also water-resistant and can absorb moisture without feeling wet. Wool is commonly used in textiles for clothing, blankets, and carpets. Different breeds of sheep produce various types of wool, each with unique characteristics. For example, Merino wool is soft and fine, while Shetland wool is coarser and more durable.
