Polyester

We come across many substances made of polyester in our daily lives.

Polyester is one of the most popular synthetic fibres.

Synthetic fibers are made of polymers.

That small unit is a chemical substance and many such units combine to form a large unit, called ‘polymer’.

The word ‘polymer’ consists of the words ‘poly’ which means many and ‘mer’ stands for part or unit.

Let us see what polyesters are made of.

Polyester is made of repeating units of a chemical called ‘ester’.

Then, it is finely processed into granules through a chemical reaction to obtain fibres.

Lastly, the obtained fibres are woven and dyed with a variety of colours.

Polyester fibre has many advantages.

Fabric made from this fibre does not wrinkle easily and hence it is widely used to make clothes.

Polyester has the property to repel water. So it dries up quickly.

Polyester is resistant to toxic chemicals and is easy to wash.

The most commonly used polyesters are : polyester mat and polyester rope.

Polyester is often mixed with other materials in the clothing industry.

For example, polycot is a mixture of polyester and cotton.

Polyester has some disadvantages too.

This fibre does not stretch and fails to absorb sweat.

Hence, when we wear a polyester garment, we notice sweat stains and feel uncomfortable.

Also, if we wear synthetic clothes made of polyester, there is a greater risk of absorbing toxic chemicals which could be harmful.

Therefore, polyesters should be used carefully.

Revision

Polyester is one of the most popular synthetic fibres.

It is made up of repeating units of a chemical called ‘ester’ which is further chemically processed to make polyester.

It is hydrophobic in nature and is easy to wash.

This fibre fails to absorb sweat and it is very uncomfortable to wear in hot weather.

Prolonged usage of this fibre can lead to absorption of toxic chemicals and can create health issues.
