Rayon is a manufactured fiber made from natural sources such as wood and agricultural products that are regenerated as cellulose fiber. The many types and grades of rayon can imitate the feel and texture of natural fibers such as silk , wool , cotton , and linen. The types that resemble silk are often called artificial silk. Rayon is manufactured from natural cellulose, and hence is not considered to be synthetic. In manufacturing terms, rayon is classified as "a fiber formed by regenerating natural materials into a usable form".

Rayon is made from purified cellulose , harvested primarily from wood pulp , which is chemically converted into a soluble compound.

It is then dissolved and forced through a spinneret to produce filaments which are chemically solidified, resulting in fibers of nearly pure cellulose. These technologies have significantly reduced the risks and have addressed the safety concern related to exposure workers to chemicals. The degree of nitrification determined its explosiveness, solubility in organic solvents such as ether and acetone , and mechanical properties when dry.

Its solubility was the basis for the first " artificial silk " by Georges Audemars in , which he called "Rayon". However, Hilaire de Chardonnet was the first to patent a nitrocellulose fiber marketed as "artificial silk" at the Paris Exhibition of Commercial production started in , but the result was flammable and more expensive than cellulose acetate or cuprammonium rayon. Because of this, production ceased early in the s. Nitrocellulose was briefly known as "mother-in-law silk". Frank Hastings Griffin invented the double-godet, a special stretch-spinning process that changed artificial silk to rayon, rendering it usable in many industrial products such as tire cords and clothing.

Nathan Rosenstein invented the "spunize process" by which he turned rayon from a hard fiber to a fabric. This allowed rayon to become a popular raw material in textiles. By , Camille Dreyfus and his brother Henri were producing acetate film for the motion picture industry.

In , after some twenty thousand separate experiments, they produced excellent laboratory samples of continuous filament yarn, something that had eluded others in the cellulose acetate industry. After World War I , attention turned to the production of acetate fibers. The first yarn was of fair quality, but sales resistance was heavy, and silk associates worked zealously to discredit acetate and discourage its use. The same characteristic also made permanent pleating a commercial fact for the first time, and gave great style impetus to the whole dress industry.

Today, acetate is blended with silk, cotton, wool, nylon, etc. Acetate shares many similarities with viscose rayon, and was formerly considered as the same textile. However, rayon resists heat while acetate is prone to melting. Acetate must be laundered with care either by hand-washing or dry cleaning, and acetate garments disintegrate when heated in a tumble dryer.

Furthermore, viscose rayon production requires carbon disulfide in production, while acetate uses safer solvents such as acetone. However, because viscose rayon is a stronger and more robust fiber than the otherwise similar acetate, it has come to dominate the market. Cellulose triacetate is a similar cellulose derivative to acetate. Acetate fiber is a modified or secondary acetate having two or more hydroxyl groups; triacetate is a primary acetate containing no hydroxyl group.

Triacetate fibers contain a higher ratio of acetate-to-cellulose than do acetate fibers. Swiss chemist Matthias Eduard Schweizer — discovered that cellulose dissolves in tetraaminecopper dihydroxide. Max Fremery and Johann Urban developed a method to produce carbon fibers for use in light bulbs in Bemberg AG in made the artificial silk a product comparable to real silk.

They named their material " viscose " because its production involved the intermediacy of a highly viscous solution. The process built on the reaction of cellulose with a strong base, followed by treatment of that solution with carbon disulfide to give a xanthate derivative. The xanthate is then converted back to a cellulose fiber in a subsequent step. The first commercial viscose rayon was produced by the UK company Courtaulds Fibres in Courtaulds formed an American division, American Viscose later known as Avtex Fibers , to produce their formulation in the United States in The viscose method can use wood as a source of cellulose, whereas other routes to rayon require lignin-free cellulose as starting material.

The use of woody sources of cellulose makes viscose cheaper, so it was traditionally used on a larger scale than the other methods. On the other hand, the original viscose process generates large amounts of contaminated wastewater.

Newer technologies use less water and have improved quality of the wastewater. Rayon was produced only as a filament fiber until the s, when methods were developed to utilize "broken waste rayon" as staple fiber. The physical properties of rayon remained unchanged until the development of high-tenacity rayon in the s. Further research and development led to high-wet-modulus rayon HWM rayon in the s. Industrial applications of rayon emerged around Substituting cotton fiber in tires and belts, industrial types of rayon developed a totally different set of properties, amongst which tensile strength and elastic modulus were paramount.

The Lyocell process relies on dissolution of cellulose products in a solvent, N-methylmorpholine N-oxide. The process starts with woody sources of cellulose and involves dry jet-wet spinning. It was developed at the now defunct American Enka and Courtaulds Fibres. Lenzing's Tencel and Birla Cellulose's Excel brands are examples of currently available lyocell fibers. Modal is a type of rayon, a semi-synthetic cellulose fiber made by spinning reconstituted cellulose.

Modal is used alone or with other fibers often cotton or spandex in clothing and household items like pajamas, underwear, bathrobes, towels, and bedsheets. Modal is processed under different conditions to produce a fiber that is stronger and more stable when it is wet than standard rayon, yet has a soft feel, similar to cotton. It can be tumble dried without damage due to its increased molecular alignment. Micro-Modal is a variant of Modal textiles. The material is softer than cotton and has desirable properties that include higher resistance to shrinking and moisture wicking.

Rayon is a versatile fiber and is widely claimed to have the same comfort properties as natural fibers, although the drape and slipperiness of rayon textiles are often more like nylon. It can imitate the feel and texture of silk , wool , cotton and linen.

The fibers are easily dyed in a wide range of colors. Rayon fabrics are soft, smooth, cool, comfortable, and highly absorbent, but they do not always insulate body heat, making them ideal for use in hot and humid climates, although also making their "hand" feel cool and sometimes almost slimy to the touch.

The durability and appearance retention of regular viscose rayon are low, especially when wet; also, rayon has the lowest elastic recovery of any fiber. However, HWM rayon high-wet-modulus rayon is much stronger and exhibits higher durability and appearance retention. Recommended care for regular viscose rayon is dry-cleaning only.

HWM rayon can be machine-washed. A sample of rayon from a skirt, photographed with a macro lens. Regular rayon has lengthwise lines called striations and its cross-section is an indented circular shape.

The cross-sections of HWM and cupra rayon are rounder. Filament rayon yarns vary from 80 to filaments per yarn and vary in size from 40 to denier. Staple fibers range from 1. Rayon fibers are naturally very bright, but the addition of delustering pigments cuts down on this natural brightness. Regular rayon or viscose is the most widely produced form of rayon. This method of rayon production has been used since the early s and it has the ability to produce either filament or staple fibers.

The process is as follows:. High wet modulus rayon HWM is a modified version of viscose that is stronger when wet. It also has the ability to be mercerized like cotton. HWM rayons are also known as "polynosic. They are also wear resistant and strong while maintaining a soft, silky feel. They are sometimes identified by the trade name Modal. High-tenacity rayon is another modified version of viscose that has almost twice the strength of HWM.

This type of rayon is typically used for industrial purposes such as tire cord. Cuprammonium rayon has properties similar to viscose; however, during its production, the cellulose is combined with copper and ammonia Schweizer's reagent. Due to the detrimental environmental effects of this production method, cuprammonium rayon is no longer produced in the United States. Highly toxic carbon disulfide is used in the production of viscose, leading to many incidents and legal cases [24] in the early years of viscose technology development.

However, the volatile carbon disulfide is lost before the rayon gets to the consumer; the rayon itself is basically pure cellulose.

Rates of disability in modern factories mainly in China, Indonesia and India are unknown. The newer technologies referred to as the closed loop manufacturing process of viscose, can recover most of the sulfur in a usable form and recycle it. Leading manufacturers of viscose now apply these latest technologies in the viscose process for effective control of hazards from these chemicals.

The impact of the textile value chain on the environment has become a major concern globally. The most important impacts include: millions of tons of textile waste going to landfill annually, plastic microfibers flowing into our waterways and oceans, pesticides and fertilizers use on fiber crops, excessive use of fresh water, greenhouse gas emissions, air and water pollution and depleted forest cover.

Rayon has historically had many of these issues, especially air and water pollution and depleted forest cover. Canopy's Hot Button Ranking offers a detailed overview of the largest global producers of viscose, ranking their raw material sourcing practices, documenting their risk of sourcing from Ancient and Endangered Forests, highlighting research and development investment towards lower impact fibers and new disruptive innovation, and noting when producers are showing leadership in supporting global forest conservation solutions.

Rayon offers an option for designers and consumers looking to enhance the sustainability attributes of their apparel. The biodegradability of various fibers in soil burial and sewage sludge was evaluated by Korean researchers.

Rayon was found to be more biodegradable than cotton, and cotton more than acetate. The more water-repellent the rayon-based fabric, the more slowly it will decompose. A ocean survey found that rayon contributed to Rising cotton prices in led clothing makers to begin replacing cotton with rayon in their fabrics.
