What is Synthetic Fibre?

Synthetic fibres are obtained from chemicals or petrochemicals and are made from raw materials such as petroleum. These materials are used to make several sorts of fibres by polymerising them into a long, linear with diverse chemical components. Synthetic fibres are used in nearly every fibre and textile technology aspect, accounting for over half of all fibre utilisation. Many kinds of synthetic polymer fibres have been studied as potentially significant commercial products; three of the most popular are nylon, polyester, and rayon.
The earliest synthetic fibres were created in the nineteenth century. The requirement for stronger fibres that could endure a lot of pressure was one of the key reasons for their development.
