Question

Which of the following is not a natural fibre ?

• A. Terylene
• B. Jute
• C. Silk
• D. Wool

Hint:

Common synthetic fibres include polyester (like Terylene), nylon, rayon, and acrylic. Being able to recognize these names is key to distinguishing them from natural fibres like cotton, wool, silk, and linen.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Natural fibres are obtained from natural sources (plants and animals). Man-made or synthetic fibres are created through chemical processes. The question asks to identify the synthetic fibre.
Step 2: Detailed Explanation:
Let's classify the given fibres:
(B) Jute: A natural fibre obtained from the stem of the jute plant.
(C) Silk: A natural fibre obtained from the cocoons of silkworms.
(D) Wool: A natural fibre obtained from the fleece of sheep or other animals.
(A) Terylene: This is a popular brand name for a type of polyester. Polyester is a synthetic polymer, made through a chemical process involving petroleum derivatives. Therefore, it is not a natural fibre.
Step 3: Final Answer:
Terylene is a synthetic fibre, while jute, silk, and wool are natural fibres.
