    Glossary wool

    natural fiber from sheep's fleece, rich in keratin

    Wool is a natural fiber obtained from the fleece of sheep and other animals, such as goats and alpacas. It is composed primarily of keratin, a protein that also makes up human hair, and is known for its crimped texture, which provides excellent insulation and elasticity. Wool is widely used in textiles for its warmth, durability, and moisture-wicking properties.
