• Types: Common types of wool include Merino, Shetland, Lambswool, and Mohair.

2. Chemical Structure of Wool Fiber:

• Wool is composed of protein fibers, primarily keratin. The basic chemical structure is a complex protein polymer with amino acid chains.

3. Physical and Chemical Properties of Wool Fiber:

• Physical Properties: Soft, resilient, elastic, breathable, and excellent insulator.
• Chemical Properties: Reactive to acids, sensitive to alkalis, susceptible to moth damage.

4. Process from Wool Fiber to Wool Fabric:

• Shearing: Wool is sheared from animals.
• Sorting and Grading: Sorting by quality.
• Scouring: Cleaning to remove impurities.
• Carding: Aligning fibers for spinning.
• Spinning: Creating yarn.
