Wool fabrics are textiles made from the fibers of sheep and other animals, such as goats (cashmere) and alpacas. Known for their warmth and durability, wool is often used in clothing, blankets, and upholstery. The natural crimp in wool fibers helps trap air, providing insulation and making it an excellent choice for cold weather. Wool is also moisture-wicking, meaning it can absorb moisture without feeling wet, which helps regulate body temperature. Additionally, it is naturally resistant to wrinkles and flames, making it a practical option for various applications. Different types of wool, like merino and tweed, offer unique textures and qualities.
