Synthetic fibres man-made fibres are produced by joining chemical monomers into polymers using a chemical reaction called polymerisation. The chemicals used are usually sodium hydroxide and carbon disulphide derivatives of coal, oil, or natural gas. The liquid from chemicals are forced through tiny holes called spinnerets to produce a filament. As the liquid comes out of the spinnerets and into the air, it cools and forms into tiny threads of continuous filament fibre.

Fiber Selection for the Production of NonwovensVIDEO ON THE TOPIC: Viscose fiber production line
Traditional materials such as cotton, linen and leather are still sourced from plants and animals. But most clothes are more likely to be made of materials and chemicals derived from fossil fuel-based crude oil. The source of synthetic fibres and fabrics is the fossil fuel crude oil. One of the oldest used fibres and the most important non-food crop in the world is cotton. Cotton production is particularly important for farmers in lower-income countries, where approximately million people are involved in its cultivation and processing 4.
These materials begin as cellulose extracted from a natural resource such as bamboo or trees that is then crushed, pulped and transformed into fibres using a similar process to the one for making polyester. The most common cellulosic fabric is viscose, prized for its silk-like qualities rayon, the first type of viscose fabric invented, was created to mimic silk.
About 2bn kilograms of raw wool per year are produced from a global herd of around 1. This roughly equates to one wool sweater per person per year for everyone on the planet 6. These figures include wool textiles used for items other than garments — such as furniture or carpets. An ancient, highly prized fabric, silk is derived from the thread produced by the silkworm species Bombyx Mori. About , MT of silk are produced each year about 0. This is one of the oldest forms of material used by humans as clothing and it remains an important fabric particularly for footwear and accessories.
Around 3. Bast fibres like flax for linen , hemp and nettle are a traditional source that has been used by humans for thousands of years, although they presently make up only a small proportion of total fabric use. These fibres are found in the inner bark layer phloem , of the plant that sit between the woody core xylem , and the outer-most layer epidermis. The long phloem cells must be separated from the xylem and epidermis before being further treated to make them ready to weave or knit into fabrics 11 , either as a pure fibre or in a mix with other fibres such as cotton.
Most bast fibres are used for other products such as paper, ropes and carpets. This is a broad category of fibres and materials that are diverse but make up only a tiny fraction of the entire amount of fabrics used. Many of these are experimental in nature — for example, they may be made from materials originally derived from mushrooms 12 , pineapple 13 or milk.

What is Acrylic Fabric: Properties, How its Made and Where
These new textile dyeing methods could make fashion more sustainable
Man-made fibre , fibre whose chemical composition , structure, and properties are significantly modified during the manufacturing process. Man-made fibres are spun and woven into a huge number of consumer and industrial products, including garments such as shirts, scarves, and hosiery; home furnishings such as upholstery, carpets, and drapes; and industrial parts such as tire cord, flame-proof linings, and drive belts. The chemical compounds from which man-made fibres are produced are known as polymers , a class of compounds characterized by long, chainlike molecules of great size and molecular weight. Many of the polymers that constitute man-made fibres are the same as or similar to compounds that make up plastics, rubbers, adhesives, and surface coatings. Indeed, polymers such as regenerated cellulose, polycaprolactam, and polyethylene terephthalate , which have become familiar household materials under the trade names rayon, nylon , and Dacron trademark , respectively, are also made into numerous nonfibre products, ranging from cellophane envelope windows to clear plastic soft-drink bottles.
Synthetic fibers, which account for about half of all fiber usage, are made from synthesized polymers based on raw materials such as petroleum. The different types of fibers are produced from widely diverse chemical compounds. Each synthetic fiber has unique properties and characteristics that suit it for specific applications. Synthetic fibers and fabrics are used in a broad variety of industries and sectors, including aerospace, apparel, architecture and construction, automotive and transportation, chemical processing, electrical and electronic, filtration, marine, medical and welding. Four synthetic fibers — polyester, polyamide nylon , acrylic and polyolefin — dominate the textile market. Polyester, the most widely used synthetic fiber, is popular for all types of clothing and for reinforcement of items such as tires, belts and hoses. Polyester fiberfill is used in pillows and high-performance outdoor wear. Carpets are commonly made of polyamide nylon , which can be blended with elastomeric fibers to produce sportswear. Acrylic fibers have some properties that resemble those of wool, but they do not absorb water, which makes them suitable for end products such as cold-weather garments and home furnishing fabrics. Polyolefin fibers, which are made from polypropylene or polyethylene, for example, are strong, colorfast and resistant to staining, mildew and abrasion.
Processing and fabrication
The most significant feature of nonwoven fabric is made directly from fibers in a continuous production line. While manufacturing nonwovens, some conventional textile operations, such as carding, drawing, roving, spinning, weaving or knitting, are partially or completely eliminated. For this reason the choice of fiber is very important for nonwoven manufacturers.
But have you ever thought about what your clothes are made of? Most of the time good qualities in clothing are associated with brands and high expenses; consumers will automatically gravitate towards familiar stores that are well-known for their quality, pricing, style etc. It goes without thinking about where in the world the garment was made, or which type of fabric was used; natural or synthetic? We never really bother to research the reason our favourite clothes are just that, our favourites. Natural fabrics—such as cotton, silk and wool—are made of animal or plant-based fibres, while synthetics are man-made and produced entirely from chemicals to create fabrics like polyester, rayon, acrylic, and many others. Over the years these synthetic fibres have increasingly grown in popularity. The demand for polyester fibres have increased by over half since , making polyester the single most used textile—overtaking cotton. Although synthetic fibres are known for better durability and cheaper manufacturing, they are acquired from petroleum products and require a complex processing procedure, like all synthetic fabrics. But natural fibres are found naturally on our planet without being scientifically invented. Knowing this, there have been many long debates between the benefits of synthetic vs. The journey of a cotton plant starts somewhere on a farm in late March.
List of textile fibres
Polymer that is to be converted into fibre must first be converted to a liquid or semiliquid state, either by being dissolved in a solvent or by being heated until molten. This process frees the long molecules from close association with one another, allowing them to move independently. The resulting liquid is extruded through small holes in a device known as a spinnerette , emerging as fine jets of liquid that harden to form solid rods with all the superficial characteristics of a very long fibre, or filament. This extrusion of liquid fibre-forming polymer, followed by hardening to form filaments, is called spinning a term that is actually more properly used in connection with textile manufacturing. Several spinning techniques are used in the production of man-made fibre, including solution spinning wet or dry , melt spinning, gel spinning a variant on solution spinning , and emulsion spinning another variation of solution spinning. One of the oldest methods for the preparation of man-made fibres is solution spinning, which was introduced industrially at the end of the 19th century. Solution spinning includes wet spinning and dry spinning. The former method was first used to produce rayon fibres, and the latter method was used to spin cellulose triacetate to acetate fibres.
Textile and Fibers
Synthetic fibers British English: synthetic fibres are fibers made by humans through chemical synthesis , as opposed to natural fibers that are directly derived from living organisms. They are the result of extensive research by scientists to improve upon 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. Synthetic fibres are created by a process known as polymerisation, which involves 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".

Textile fibres or textile fibers see spelling differences can be created from many natural sources animal hair or fur, insect cocoons as with silk worm cocoons , as well as semisynthetic methods that use naturally occurring polymers, and synthetic methods that use polymer-based materials, and even minerals such as metals to make foils and wires. The textile industry requires that fibre content be provided on content labels.
What Are Our Clothes Made From?
Read more. All textiles are made up of fibres that are arranged in different ways to create the desired strength, durability, appearance and texture. The fibres can be of countless origins, but can be grouped into four main categories. Natural fibres, with the exception of silk, have a relatively short fibre length, measured in centimetres.
Additional Information. Show source.
Most textile materials originate from a single, fine structure called a fibre. Some fibres are naturally short in length and are known as staple fibres , eg cotton, wool and linen. Other manufactured synthetic fibres are known as continuous filament , eg polyester and nylon.
