Question

(i) Which one of the following is a synthetic fibre?
(a) Nylon
(b) Rayon
(c) Polyester
(d) All of these

Answer 1

Answer:

D is the correct answer

All of these are synthetic fibres

Answer 2

Answer:

(d)All of these

Explanation:

• Synthetic fibre is a manmade fibre obtained from petrochemical sources. It is a chain of small units of chemical substances joined together. These single units are called the monomers or monomeric units which combine to form polymers.

The fibres are of two types :

(a) natural fibres are obtained from natural sources like cotton, silk, wool, etc.

(b) man-made fibres are Rayon, nylon, polyester, etc.

There exists a variety of synthetic polymers.

• Nylon was the first commercially synthesized fibre. It is very strong and its fabric is lustrous which is synthesized from coal, air, and water.

• Polyester is one of the most popular textiles. Also, it is most popular among fibres. The monomeric units called esters make up polyesters. It is widely used in cloth making.

• Rayon is the type of fibre, synthesized from wood pulp. This is soft, comfortable, and resembles silk, so it is also known as artificial silk which is cheaper than silk.

Options (a)nylon, (b)Rayon, and (c) polyester are few among the synthesized fibres,

Hence option (d) all of these is correct.
