Question

Which of the following is a synthetic fibre?
(A)- Cotton
(B)- Nylon
(C)- Jute
(D)- Wool

Answer 1

Hint: Synthetic fibres are those which are not obtained directly from natural sources like plants and animals. Synthetic fibres are either the modification of natural fibres or are directly produced in the laboratories.

Complete step by step solution:
A thin thread that is obtained from either natural substance or artificial substance, especially one that is used for making cloth or rope is known as fibre.
If the fibre is obtained from plants and animals, then it is known as natural fibre. Man-made fibres which are modified natural fibres or produced in the laboratories are known as synthetic fibre.
Some natural fibres obtained from plants are cotton, jute, etc and natural fibres that are obtained from animals are wool, silk, etc.
So, nylon is a synthetic fibre. Nylon is a chemical polyamide polymer.
It can be moulded into any shape and it is the strongest synthetic fibre. It is easy to dye but does not absorb water easily. It is highly durable because it is elastic.
It has a good resistant property as it resists oil, grease, moths, fungus, and many other pests. Since it can be moulded into any shape, it can be made into palates and even powder also.
Because of so many properties, it is used for making a thread, reel thread, ropes, seatbelts, sarees, tracksuits, raincoats, fishing nets, swimming wears, sleeping bags, etc.

So, the correct answer is an option (D)- Nylon.

Note: Some of the other important synthetic fibres which are commercially used are rayon, polyester, acrylic, terylene, cotton blend, etc. Synthetic fibre is long-lasting as compared to natural fibre.
