How are synthetic fibres made?

Fibres like cotton, wool, silk, linen and hair are natural fibres which are produced by plants and animals. Synthetic fibres are rayon, nylon, dacron, saran, etc. In these, atoms of carbon, hydrogen, oxygen and other elements are combined to create new substances. Coal, oil, air and water are used as the raw materials for synthetic fibres. The process is called polymerization. Polymers are long, molecular chains.
