How to define synthetic fibre in terms of petrochemical
Answers
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, forming a fibre. These fibers are called synthetic or artificial fibers.Synthetic fibres are created by a process known as polymerisation which includes combining monomers to make a long chain or polymer.The word polymer comes from a Greek prefix "poly" which means "many" and suffix "mer" which means "single units".(Note:each single units of a polymer is called monomer).Polymerisation are of two types:linear polymerisation and Cross-linked polymerisation. Example are Rayon, Nylon and Polyester.
