Question

The polymer that is used as a substitute for wool in making commercial fibres is :

• A. Melamine
• B. nylon-6, 6
• C. polyacrylonitrile
• D. Buna-N

Answer 1

The Correct Option is C

The question asks about the polymer used as a substitute for wool in making commercial fibers. Let's analyze the options provided and identify the correct answer.

1. Melamine: Melamine is commonly used in making plastics and adhesives but is not used as a wool substitute.
2. Nylon-6, 6: Nylon-6, 6 is a type of synthetic polymer known for its strength and resistance but typically used in making products like ropes, carpets, and clothing, not as a wool substitute.
3. Polyacrylonitrile: This polymer is often used in making synthetic fibers like Acrylic, which is widely used as a substitute for wool in textiles due to its wool-like texture and warmth.
4. Buna-N: Buna-N, or nitrile rubber, is used in the manufacture of oil-resistant products like hoses and gaskets but is not a wool substitute.

Based on the above analysis, the correct answer is polyacrylonitrile. It is commonly used to produce acrylic fibers, which mimic the properties of wool, making it an excellent substitute in the textile industry.
