Synthetic fiber

Synthetic fibers or fibres are the result of extensive research by scientists to improve on naturally occurring animal and plant fibers. In general, synthetic fibers are created by extruding fiber forming materials through spinnerets into air and water, forming a thread. Before synthetic fibers were developed, artificially manufactured fibers were made from polymers obtained from petro chemicals. These fibers are called synthetic or artificial fibers. Some fibers are manufactured from plant-derived cellulose.

Early experiments

Joseph Swan created the first synthetic fiber.

Joseph Swan invented the first synthetic fiber in the early 1880s.[1] His fiber was drawn from a cellulose liquid, formed by chemically modifying the fiber contained in tree bark. The synthetic fiber produced through this process was chemically similar in its potential applications to the carbon filament Swan had developed for his incandescent light bulb, but Swan soon realized the potential of the fiber to revolutionise textile manufacturing. In 1885 he unveiled fabrics he had manufactured from his synthetic material at the International Inventions Exhibition in London.[2]

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 silk worms. 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,[3] which he displayed at the Paris Exhibition of 1889.[4] Unfortunately, Chardonnet's material was extremely flammable, and was 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 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.[6]

Nylon, the first synthetic fiber, 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 introduced by John Rex Whinfield and James Tennant Dickson,[7][8] British chemists working at the Calico Printers' Association, in 1941. They produced and patented the first polyester fibre which they named Terylene, also known as Dacron, equal to or surpassing nylon in toughness and resilience.[9] ICI and DuPont went on to produce their own versions of the fibre.


Synthetic fibers are made from synthesized polymers or small molecules. The compounds that are used to make these fibers come from raw materials such as petroleum based chemicals or petrochemicals. These materials are polymerized into a long, linear chemical that bond two adjacent carbon atoms. Differing chemical compounds will be used to produce different types of fibers.

Synthetic fibers account for about half of all fiber usage, with applications in every field of fiber and textile technology. Although many classes of fiber 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 per cent.[10]

There are several methods of manufacturing synthetic fibers but the most common is the Melt-Spinning Process. It involves heating the fiber until it begins to melt, then you must draw out the melt with tweezers as quickly as possible. The next step would be to draw the molecules by aligning them in a parallel arrangement. This brings the fibers closer together and allows them to crystallize and orient. Lastly, is Heat-Setting. This utilizes heat to permeate the shape/dimensions of the fabrics made from heat-sensitive fibers.


Synthetic fibers are more durable than most natural fibers and they 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 the all fibers to break down and wear away. Natural fibers are much more sensitive than synthetic blends. This is mainly because natural products are biodegradable. Natural fibers susceptible to larval insect infestation. Synthetic fibers are not a good food source for fabric-damaging insects.

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. Some fabrics are also designed to stretch in specific ways, which makes them more comfortable to wear.

Cotton is resource intensive: it takes a lot of water to farm cotton. Wool sheep also need water, and a lot of grazing land in order to survive, thus it is claimed by some that although synthetic fiber production does involve some carbon emissions, the environmental footprint of many fibers is much lower.

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

  • Synthetic fibers burn more readily than natural.
  • Prone to heat damage. Melt relatively easily.
  • Prone to damage by hot washing.
  • More electrostatic charge is generated by rubbing than with natural fibres.
  • Not skin friendly, so it is uncomfortable for long wearing.
  • Allergic to some people.
  • Non-biodegradable in comparison to natural fibres.
  • Do not absorb sweat during summers.

Common synthetic fibers

Common synthetic fibers include:

Specialty synthetic fibers include:

Other synthetic materials used in fibers include:

Modern fibers that are made from older artificial materials include:

In the horticulture industry synthetics are often used in soils to help the plants grow better. Examples are:

  • expanded polystyrene flakes
  • urea-formaldehyde foam resin
  • polyurethane foam
  • phenolic resin foam
