    Question

    Choose the fiber which is termed artificial wool.

    1. Rayon
    2. Acrylic
    3. Nylon
    4. Silk

    Hint:

    A man-made polymer is an industrial-produced chemical substance consisting of monomers linked together by covalent bonds which are also called synthetic polymers. This synthetic polymer is usually obtained from petroleum after the undergoing refining and cracking process.

    The correct answer is: Acrylic

      • Acrylic is termed artificial wool. 
      • Polyester is a synthetic fiber obtained from coal or petroleum.
      • Polyester is durable but breathable and not designed to absorb liquids.
      • Acrylic fibers are made using acrylonitrile or vinyl cyanide polymers.
      • Acrylic is often considered an imitation of wool because it retains heat.
