Synthetic fibers (British English: synthetic fibres) are fibers made by humans with chemical synthesis, as opposed to natural fibers that humans get from living organisms with little or no chemical changes.
They are the result of extensive research by scientists to improve on naturally occurring animal fibers and plant fibers. In general, synthetic fibers are created by extruding fiber-forming materials through spinnerets into air and water, forming a thread
These fibers are called synthetic or artificial fibers. Some fibers are manufactured from plant-derived cellulose and are thus semisynthetic, whereas others are totally synthetic, being made from crudes and intermediates including petroleum, coal, limestone and water.
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.
