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 Hilaire de Chardonnet, a French engineer and industrialist, who invented the first artificial silk, which he called "Chardonnet silk". In the late 1870s, Chardonnet was working with Louis Pasteur on a remedy to the epidemic that was destroying French 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. It would not take long for these synthetic fibers to obtain a legitimate foothold within the textile industry. Soon these fibers would take a hold of the textile marketplace leading to the decreased demand of natural fibers. The benefits of these synthetic fibers would ultimately catch the attention of most consumers.

Commercial products

Nylon was first synthesized by Wallace Carothers at DuPont.

The first successful process was developed in 1894 by English chemist Charles Frederick Cross, and his collaborators Edward John Bevan and Clayton Beadle. They named the fiber "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]

Nylon, the first synthetic fiber in the "fully synthetic" sense of that term,[citation needed] was developed by Wallace Carothers, an American researcher at the chemical firm DuPont in the 1930s. It soon made its debut in the United States as a replacement for silk, just in time for the introduction of rationing during World War II. Its novel use as a material for women's stockings overshadowed more practical uses, such as a replacement for the silk in parachutes and other military uses like ropes.

The first polyester fiber was patented in Britain in 1928 by the International General Electric company.[5] It was also produced by British chemists working at the Calico Printers' Association, John Rex Whinfield and James Tennant Dickson,[6][7] in 1941. They produced and patented one of the first polyester fibers which they named Terylene, also known as 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]

Descriptions

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]

Pros

Synthetic fibers are more durable than most natural fibers and will readily pick-up different dyes. In addition, many synthetic fibers offer consumer-friendly functions such as stretching, waterproofing and stain resistance. Sunlight, moisture, and oils from human skin cause all fibers to break down and wear away. Natural fibers tend to be much more sensitive than synthetic blends. This is mainly because natural products are biodegradable. Natural fibers are susceptible to larval insect infestation; synthetic fibers are not a good food source for fabric-damaging insects. [citation needed]

Compared to natural fibers, many synthetic fibers are more water-resistant and stain-resistant. Some are even specially enhanced to withstand damage from water or stains.

Synthetic fibers can be made out of recycled clear plastic allowing natural resources to be conserved.

Cons

Most of synthetic fibers' disadvantages are related to their low melting temperature:

  • Mono-fibers do not trap air pockets like cotton and thus provide poor insulation.
  • Synthetic fibers burn more rapidly than natural fibers.
  • Prone to heat damage like damage by hot washing.
  • Melt relatively easily.
  • More electrostatic charge is generated by rubbing than with natural fibers.
  • Some consumers claim that textiles made with synthetic fibers are less skin-friendly or may cause discomfort over long periods of wear.[citation needed]
  • Non-biodegradable or far less biodegradable in comparison to natural fibers.[citation needed]
  • Most synthetic fibers absorb very little moisture and thus may become sticky when the body sweats.
  • Synthetic fibers are a source of microplastic pollution from laundry machines.[11]
