Question

Synthetic fibre and its uses
​

Answer 1

Answer:

Explanation:

ynthetic fibre are man-made fibres, most of them are prepared from raw material (petroleum) called petrochemicals. All fabrics are obtained from fibres and fibres are obtained from artificial or man-made sources. It consists of small unit or a polymer which is made from many repeating units known as monomers. Example: rayon, nylon, polyester, etc. These fibre finds its applications in household articles like ropes, bucket, furniture, etc. Following are some of the most commonly used synthetic fibres:

Synthetic Fibre

Rayon

This is a type of synthetic fibre obtained from wood pulp.

Rayon is soft, absorbent and comfortable.

It is easy to dye in wide range of colors.

Rayon is mixed with cotton to make bedsheets.

Rayon is mixed with wool to make carpets.

Nylon

This type of synthetic fibre is obtained from coal, water and air.

Nylon is very lustrous, easy to wash and elastic.

It dries quickly and retains its shape.

Nylon finds its application in seat belts of car, sleeping bags, socks, ropes, etc.

Nylon is also used in ropes for rock climbing, making parachutes and fishing nets.

Polyester

This type of synthetic fibre is obtained from coal, water, air and petroleum.

Polyester is made from repeating units of chemical known as esters.

Polyester is easy to wash and it remains wrinkle free and it is quite suitable in making dress material.

Polyester retains its shape and remains crisp.

Polyester is used in making ropes, nets, raincoats, jackets, etc.

Advantages

Synthetic fibres are very durable and do not wrinkle easily

They are elastic and can be easily stretched out

They are strong and can sustain heavy load.

It is soft and hence it is used in clothing material.

It is cheaper as compared to natural fibres.

Disadvantages of synthetic fibres

Most synthetic fibres do not absorb moisture.

Synthetic fibre can be affected if washed using hot water.

It catches fire easily as compared to natural fibre

Answer 2

Synthetic fibres

• Synthetic fibres are created by synthesising tiny molecules of polymers.
• These fibres are made of natural materials like chemicals petroleum-based or petrochemicals.
• Polymerization of such materials produces a chemical that bonds two neighbouring carbon atoms.
• All fabrics are formed from fibres, which can be derived from natural or artificial sources.
• They are made up of a tiny unit as well as a polymer that is made up of multiple repetitive units are referred to as monomers.

Uses

• It is used in the manufacturing of ropes, fishing equipment, & safety belts.
• Polyester is just a wrinkle-free, simple fabric manufactured from coal power.
• It is utilised in the manufacture of hats, raincoats, & ropes.
