Answer:
The clothes which we wear ae made of fabrics.
Synthetic fibers are made from synthesized polymers of small molecules. The compounds that are used to make these fibers come from raw materials such as petroleum based chemicals or petrochemicals. These materials are polymerized into a chemical that bonds two adjacent carbon atoms.
Fabrics are made from fibres obtained from the natural or artificial sources.
The synthetic fibres are made by the human beings, hence they are called as synthetic or man made fibres.
A synthetic fibre is the chain of small units joined together. Each small unit is actually a chemical substance.
The types of synthetic fibres are
Rayon
The fibre obtained by the chemical treatment of wood pulp is called as Rayon or artificial silk.
Nylon
Nylon is the other man-made fibre. In 1931, it was made without using any natural raw material. It was prepared from coal, water and air.
