Question

By which properties synthetic fibres are preferred to make dress material?

Answer 1

Hint: Polymers found in natural gas and by products of petroleum are used to make synthetic fibres. They are man-made 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 are also known as petrochemicals. All fabrics are derived from fibres while fibres are made from artificial man-made resources. Fibres include nylon, acrylics, polyurethane and polypropylene.
Synthetic fibers are classified as follows,
-Rayon: This type of synthetic fibre is produced or manufactured from wood pulp. Rayon fibres are soft, absorbent and comfortable. It is easy to dye in a wide range of colours. Cotton is mixed with rayon to make soft bed sheets. Carpets are made by mixing rayon and carpets.
-Polyester: Coal, petroleum, water and air are used to obtain this type of synthetic fibre. Repeating units of a chemical known as esters is used to make polyester. Polyester remains crisp and retains its shape.
-Nylon: Coal, water and air are used to make this type of synthetic fibre. Nylon is very lustrous, elastic and easy to wash. Nylon dries very quickly and maintains its shape. Nylon is used in seatbelts of cars, sleeping bags, socks, etc.
Properties of synthetic fibres are as follows,
Synthetic fibres are durable.
-They do not wrinkle easily.
-They are strong.
-They can sustain heavy load.
-They are used in clothing material because they are soft.
-Compared to natural fibres, they are cheaper.
Therefore, we use synthetic fibers to make dresses as they are cheap, durable, get dry easily and easy to maintain.

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