Question

Polyester is a ______ fibre

Answer 1

Answer:

artificial or synthetic

Explanation:

e , Polyester is a category of polymers that contain the ester functional group in their main chain. ... The fibres do not have “pores” like natural fabrics such as silk and cotton. Polyester is often blended with natural fibers to improve its performance.

Answer 2

Answer:

Synthetic fibre

Wool, cotton, and other natural fibres are products of nature. Polyester is a synthetic material. It is an illustration of synthetic fibre. Chemical processes are used by humans to create synthetic fibre.

Explanation:

• A group of polymers known as polyester have an ester functional group in each repeat unit of their main chain. It most frequently refers to a type of substance called polyethene terephthalate when used as a particular term (PET).
• Both manmade substances like polybutyrate and naturally occurring compounds found in plants and insects can be used to make polyesters. The majority of synthetic polyesters are not biodegradable, however, a small number of synthetic and certain natural polyesters are. Clothing often contains synthetic polyesters.
• Sometimes, natural and polyester fibres are spun together to create a fabric with a unique blend of qualities. Cotton-polyester mixes have the potential to be robust, tear- and wrinkle-resistant, and shrinkage-reducing.
• Polyester-based synthetic fibres are more resistant to water, wind, and the environment than fibres made from plants. They are more flammable and prone to melting.
