Fibers that are made by man from chemical substances are called synthetic fibre. Example: Rayon, Nylon etc. The synthetic fibres are mostly obtained from petroleum. The fabric made up of synthetic fibres is called synthetic fabric.
Types of Synthetic Fibres : Depending upon the type of chemicals used for manufacturing synthetic fibres, there are four major types of synthetic fibres (or man - made fibres). These are :
(i) Rayon. (ii) Nylon (iii) Polyester, and (iv) Acrylic.
NOTE : Rayan is a man-made fibre made from a natural material called cellulose (obtained from wood pulp) Nylon, polyester and acrylic are fully synthetic fibres which do not require a natural material (like cellulose) for their manufacture. These fully synthetic fibres are prepared by a number of processes by using raw materials (or chemical compounds) of petroleum origin, called petrochemicals.
