Verified Answer
Read the given statements and mark the appropriate answer.Statement 1:...
The most common type of chemical reaction used to make polyester takes place at high temperatures in a vacuum. A petroleum by-product, alcohol, and carboxyl acid are mixed to form a compound known as monomer or “ester.” This reaction is known as polymerization.
Polyester is a synthetic petroleum-based fibre, and is therefore a non-renewable carbon-intensive resource. Nearly 70 million barrels of oil are used each year to make polyester around the world, which is now the most commonly used fiber in making clothes.

Polyester
Polyester fibre does not get wrinkled easily. Hence, a fabric made from this fibre is easy to wash and does not need to be ironed - which makes it suitable for dress material.
Polyester is made up of two words - 'poly' which means many, and 'ester' which is a chemical.
Esters are chemicals which give fruits their smell.
Name some types of Polyester fibres.
Some popular polyester fibres are:
• Terylene (often known by brand name Dacron) which can be drawn into a very fine fibre and can be woven like any other yarn.
• Polyethylene terephthalate (P.E.T.) is used for making wires, films, bottles, utensils and other products.
What are blended fibres? Give some examples.
Blended fibres are formed by mixing natural and synthetic fibres. Polyester is often used in blended fibres. For Example,
• Polywool is made by mixing polyester and wool.
• Polycot is made my mixing polyester and cotton.
• Terrycot is made by mixing Terylene and cotton.
Uses of Polyester
Since polyester is strong, wrinkle-resistant and water-resistant, it has several uses. It can be used to:
• Make a variety of textiles (including sarees, curtains, dress materials etc.) and can be blended with natural fibres (like cotton and wool)
• Make films, magnetic recording tapes, etc (as Mylar)
• Make sails of sailboats
• Make water hoses for firefighting purposes
