Question

Nylon fibre is useful, because of following properties:
(A) Soft, Strong and Light.
(B) Transparent, Light and Easy to wash.
(C) Strong, Elastic and Light
(D) Hard, Inexpensive and Strong.

Answer 1

Hint :We know that the polymers found in natural gas and by products of petroleum are used to make synthetic fibres. They are manmade products. Dress materials are usually easily obtainable along with high tensile strength and easy to wash.

Complete Step By Step Answer:
Synthetic fibres are prepared mostly from petroleum which is also known as petrochemicals. All fabrics are derived from fibres while fibres are made from artificial man-made resources. Fibres are substances used to manufacture materials and fabrics such as cables, wires, clothes, curtains, and bed sheets. They are usually long, thin, and flexible, making them appropriate for manufacturing bendable, strong materials. Some of the most common types of fibres are cotton, silk, jute, linen, nylon, rayon etc. Also known as man made or artificial fibres, these are produced through chemical synthesis. Synthetic fibres were first developed in the nineteenth century. One of the main reasons for their creation was the need for stronger fibres that could withstand a lot of pressure. A lot of these fibres have extended use other than textiles.
Properties of synthetic fibres are as follows:
-Synthetic fibres are durable.
-They do not wrinkle easily.
-They are strong.
-They can sustain heavy loads.
-They are used in clothing material because they are soft.
Compared to natural fibres, they are cheaper.
Thus, Nylon fibre is strong, elastic and light. It is lustrous and easy to wash. So, correct answer is option C.

Note :
Remember that the uses of synthetic fibres are as follows, it is used to make nets, ropes, jackets, raincoats. It is used in car seatbelts, sleeping bags, and socks. It is quite suitable in making dress materials because it is easy to wash and remains wrinkle free.
