Wool is a natural fiber obtained from the hair of various animals, primarily sheep, but also goats, camels, llamas, alpacas, and rabbits. Key steps in the production of wool: 1. Shearing: The wool is cut or shorn from the animal's coat. 2. Cleaning: The raw wool is washed to remove dirt, grease, and other impurities (scouring). 3. Processing: The wool is then spun into yarn using either the worsted or woolen system, and finally woven or knitted into fabrics. Types of wool include Merino, Cashmere, Angora, Mohair, and Lambswool, each with unique characteristics.
