Synthetic fibers or synthetic fibres (in British English; see spelling differences) are fibers made by humans through chemical synthesis, as opposed to natural fibers that are directly derived from living organisms, such as plants (like cotton) or fur from animals. They are the result of extensive research by scientists to replicate naturally occurring animal and plant fibers. In general, synthetic fibers are created by extruding fiber-forming materials through spinnerets, forming a fiber. These are called synthetic or artificial fibers. The word polymer comes from a Greek prefix "poly" which means "many" and suffix "mer" which means "single units". (Note: each single unit of a polymer is called a monomer).

The first synthetic fibres

Nylon was the first commercially successful synthetic thermoplastic polymer. DuPont began its research project in 1927. The first nylon, nylon 66, was synthesized on February 28, 1935, by Wallace Hume Carothers at DuPont's research facility at the DuPont Experimental Station.

The next step was taken by

silkworms. Failure to clean up a spill in the darkroom resulted in Chardonnet's discovery of nitrocellulose as a potential replacement for real silk. Realizing the value of such a discovery, Chardonnet began to develop his new product,[1] which he displayed at the Paris Exhibition of 1889.[2]
Chardonnet's material was extremely flammable, and subsequently replaced with other, more stable materials.

Commercial products

Nylon was first synthesized by Wallace Carothers at DuPont.

The first successful process was developed in 1894 by English chemist

viscose", because the reaction product of carbon disulfide and cellulose in basic conditions gave a highly viscous solution of xanthate.[3] The first commercial viscose rayon was produced by the UK company Courtaulds in 1905. The name "rayon" was adopted in 1924, with "viscose" being used for the viscous organic liquid used to make both rayon and cellophane. A similar product known as cellulose acetate was discovered in 1865. Rayon and acetate are both artificial fibers, but not truly synthetic, being made from wood.[4]

stockings overshadowed more practical uses, such as a replacement for the silk in parachutes and other military uses like ropes
.

The first

Dacron, equal to or surpassing nylon in toughness and resilience.[8] ICI and DuPont
went on to produce their own versions of the fiber.

The world production of synthetic fibers was 55.2 million tonnes in 2014.[9]

About half of all fibres are synthetic, with applications in every field of fiber and textile technology. Although many classes of fibers based on synthetic polymers have been evaluated as potentially valuable commercial products, four of them - nylon, polyester, acrylic and polyolefin - dominate the market. These four account for approximately 98 percent by volume of synthetic fiber production, with polyester alone accounting for around 60 percent.[10]

Synthetic fibers are a source of

microplastic pollution from laundry machines.[11]
