Rayon , also called viscose and commercialised in some countries as sabra silk or cactus silk , is a semi-synthetic fiber , made from natural sources of regenerated cellulose , such as wood and related agricultural products. It has the same molecular structure as cellulose. Many types and grades of viscose fibers and films exist. Some 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 . It can be woven or knit to make textiles for clothing and other purposes.
71-423: The U.S. Flammable Fabrics Act is an act that was passed in 1953 to regulate the manufacture of highly flammable clothing. It was enacted after years of rayon viscose fabrics being proven to be the primary cause of quick starting, high temperature fires as well as having the secondary effect of causing illnesses in factory workers. Viscose is the key word when describing the chemical dangers of rayon fabrics, because
142-566: A century. 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 being produced in the United States . The process has been described as obsolete, but cuprammonium rayon is still made by one company in Japan. Tetraamminecopper(II) sulfate
213-408: A chemical named carbon disulfide is used to convert cellulose into a viscose fabric capable of being threaded together for clothing. This is an important distinction to make for the sake of clarity as cellulose fabrics are still commonly advertised as "green" in the sense that the fabric is derived from the cellulose in plants, but the introduction of carbon disulfide in the manufacturing process creates
284-409: A discrepancy in the ability to identify natural fibers in a marine environment via Fourier transform infrared spectroscopy . Later research of oceanic microfibers instead found cotton being the most frequent match (50% of all fibers), followed by other cellulosic fibers at 29.5% (e.g., rayon/viscose, linen, jute, kenaf, hemp, etc.). Further analysis of the specific contribution of rayon to ocean fibers
355-584: A few years the process became highly successful and was responsible for transforming the silk weaver into the world's leading man-made fibre production company. Courtaulds also entered the market of cellulosics ( viscose and acetate ) in North America with the setting up of the American Viscose Corporation (AVC) in 1909. The investment in the US was highly successful, but its sale at a knock-down price
426-820: A highly viscous solution. Cross and Bevan took out British Patent No. 8,700, "Improvements in Dissolving Cellulose and Allied Compounds" in May, 1892. In 1893, they formed the Viscose Syndicate to grant licences and, in 1896, formed the British Viscoid Co. Ltd. The first commercial viscose rayon was produced by the UK company Courtaulds Fibres in November 1905. Courtaulds formed an American division, American Viscose (later known as Avtex Fibers), to produce their formulation in
497-437: A hostile takeover attempt by Imperial Chemical Industries was defeated. Throughout the 1980s, Courtaulds conducted research on solvent-spun cellulose fibres, using amine oxides. This process had previously been suggested by Eastman-Kodak, but their patent was nearing expiration. By the 1990s, this research led to pilot scale facilities and a subsequent patent battle with Lenzing. These companies initially cross-licensed, but
568-551: A less environmentally-harmful process for making Rayon led to the development of the lyocell method for producing Rayon. The lyocell process was developed in 1972 by a team at the now defunct American Enka fibers facility at Enka, North Carolina . In 2003, the American Association of Textile Chemists and Colorists (AATCC) awarded Neal E. Franks their Henry E. Millson Award for Invention for lyocell. In 1966–1968, D. L. Johnson of Eastman Kodak Inc. studied NMMO solutions. In
639-502: A pilot plant in 1990, and commercial production in 1997, with 12 metric tonnes/year made in a plant in Heiligenkreuz im Lafnitztal , Austria. When an explosion hit the plant in 2003 it was producing 20,000 tonnes/year, and planning to double capacity by the end of the year. In 2004 Lenzing was producing 40,000 tons [sic, probably metric tonnes]. In 1998, Lenzing and Courtaulds reached a patent dispute settlement. In 1998 Courtaulds
710-406: A reaction that is remarkably toxic to the workers who are developing and working with the fabric. There was also a series of tragic deaths in the 1940s caused by the highly flammable nature of the fabric involving children who were wearing long rayon pile cowboy chaps or brushed rayon sweaters. The Federal Trade Commission was initially placed as the enforcement authority but this responsibility
781-487: A significant role in the development of Courtaulds from a rather sedate, man-made fibres producer to the world's largest textile manufacturer, a position the company attained in the mid-1970s. The economics department then influenced the early stages of the subsequent extensive restructuring of the company, a process that culminated in the demerging of its textile activities as a separately quoted company in March 1990. In 1962

#1733085074365852-408: A soft, silky feel. They are sometimes identified by the trade name Modal. 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 can be tumble-dried without damage. The fabric has been known to pill less than cotton due to fiber properties and lower surface friction. The trademarked Modal
923-414: A solvent, N-methyl morpholine N-oxide (NMMO). The process starts with cellulose and involves dry jet-wet spinning. It was developed at the now defunct American Enka Company and Courtaulds Fibres. Lenzing's Tencel is an example of a lyocell fiber. Unlike the viscose process, the lycocell process does not use highly toxic carbon disulfide. "Lyocell" has become a genericized trademark, used to refer to
994-424: A 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 the quality of the wastewater. The raw material for viscose is primarily wood pulp (sometimes bamboo pulp ), which
1065-480: 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 rayons are low, especially when wet; also, rayon has the lowest elastic recovery of any fiber. However, HWM rayon (high-wet-modulus rayon)
1136-455: A year until 2015. In May 2006, Sara Lee sold Courtaulds Textiles (but not its pension debt) for an undisclosed sum. It was bought by a consortium led by PD Enterprise Limited, a private company based in Hong Kong. At the time, Courtaulds had about a thousand employees in the UK, of whom 300 were employed at a tights factory. Times Brenda Barnes commented that Sara Lee had effectively "given away"
1207-408: Is also used as a solvent. The viscose process builds 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 viscose method can use wood as a source of cellulose, whereas other routes to rayon require lignin -free cellulose as
1278-477: 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. Unless the chemicals are handled carefully, workers can be seriously harmed by the carbon disulfide used to manufacture most rayon. To prepare viscose, pulp is treated with aqueous sodium hydroxide (typically 16–19% by mass ) to form " alkali cellulose ", which has
1349-437: Is emitted per kilogram of rayon produced. Control technologies have enabled improved collection of carbon disulfide and reuse of it, resulting in a lower emissions of carbon disulfide. These have not always been implemented in places where it was not legally required and profitable. Carbon disulfide is volatile and is lost before the rayon gets to the consumer; the rayon itself is basically pure cellulose . Studies from
1420-584: Is made by a slightly different solvent recovery process, and is considered a different fiber by the US FTC. Tencel lyocell was first produced commercially by Courtaulds' Grimsby plant in England. The process, which dissolves cellulose without a chemical reaction, was developed by Courtaulds Research. Birla Cellulose is also a volume manufacturer of rayon. They have plants located in India , Indonesia and China . Accordis
1491-413: Is made by spinning beech-tree cellulose and is considered a more eco-friendly alternative to cotton, as the production process uses on average 10–20 times less water. In 2018, viscose fiber production in the world was approximately 5.8 million tons, and China was the largest producer with about 65% of total global production. Trade names are used within the rayon industry to label the type of rayon in
SECTION 20
#17330850743651562-576: 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. 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 980 filaments per yarn and vary in size from 40 to 5000 denier . Staple fibers range from 1.5 to 15 denier and are mechanically or chemically crimped. Rayon fibers are naturally very bright, but
1633-401: Is produced from the ripened solutions by treatment with a mineral acid, such as sulfuric acid . In this step, the xanthate groups are hydrolyzed to regenerate cellulose and carbon disulfide: Aside from regenerated cellulose, acidification gives hydrogen sulfide (H 2 S), sulfur, and carbon disulfide. The thread made from the regenerated cellulose is washed to remove residual acid. The sulfur
1704-475: Is stretched as it is made, aligning the molecules along the fibers. Two forms are available: "polynosics" and "high wet modulus" (HWM). High-wet-modulus rayon is a modified version of viscose that is stronger when wet. It can be mercerized like cotton. HWM rayons are also known as "polynosic". Polynosic fibers are dimensionally stable and do not shrink or get pulled out of shape when wet like many rayons. They are also wear-resistant and strong while maintaining
1775-403: Is then removed by the addition of sodium sulfide solution, and impurities are oxidized by bleaching with sodium hypochlorite solution or hydrogen peroxide solution. Production begins with processed cellulose obtained from wood pulp and plant fibers. The cellulose content in the pulp should be around 87–97%. The steps: The lyocell process relies on dissolution of cellulose products in
1846-526: The Vereinigte Glanzstoff Fabriken AG in Oberbruch (near Aachen ). Improvement by J. P. Bemberg AG in 1904 made the artificial silk a product comparable to real silk. English chemist Charles Frederick Cross and his collaborators, Edward John Bevan and Clayton Beadle, patented their artificial silk in 1894. They named it "viscose" because its production involved the intermediacy of
1917-422: The firebrat —can eat rayon, but damage was found to be minor, potentially due to the heavy, slick texture of the tested rayon. Another study states that "artificial silk [...] [was] readily eaten" by the grey silverfish . A 2014 ocean survey found that rayon contributed to 56.9% of the total fibers found in deep ocean areas, the rest being polyester , polyamides , acetate and acrylic . A 2016 study found
1988-459: The "prohibition of the introduction or movement in interstate commerce of articles of wearing apparel and fabrics which are so highly flammable as to be dangerous when worn by individuals, and for other purposes." This distinction was an integral one because it drew a clear line in the sand that American companies would not be allowed or expected to tolerate highly flammable fabrics to be manufactured or used in manufacturing. This act would also lead to
2059-463: The 1800s). Data on these additional risks came out in the 1960s. Courtaulds worked hard to prevent publication of this data in the UK. Courtaulds was one of the earliest companies in the UK to establish an economics department. In the three decades following World War II that department made notable contributions to the understanding of investment appraisal and the formulation of British, and later European, trade policy. The function also played
2130-694: The 1930s show that 30% of American rayon workers experienced significant health impacts due to carbon disulfide exposure. Courtaulds worked hard to prevent this information being published in Britain. During the Second World War , political prisoners in Nazi Germany were made to work in appalling conditions at the Phrix rayon factory in Krefeld . Nazis used forced labour to produce rayon across occupied Europe. In
2201-682: The 1930s. Wishing to reduce their dependence on natural silk, in 1904 Courtaulds acquired the Cross and Bevan 's patents to the viscose process for manufacturing artificial silk or rayon from dissolving pulp . They set up the first factory to produce it in Coventry UK in 1905. The early yarns were first woven into fabrics at the Halstead Mill in Essex in March 1906, but the process remained troublesome until further inventions improved yarn strength. However, in

2272-502: The 1980s the patent was licensed by Akzo to Courtaulds and Lenzing. The fibre was developed by Courtaulds Fibres under the brand name "Tencel" in the 1980s. In 1982, a 100 kg/week pilot plant was built in Coventry, UK, and production was increased tenfold (to a ton/week) in 1984. In 1988, a 25 ton/week semi-commercial production line opened at the Grimsby, UK, pilot plant . The process
2343-464: The 1990s, viscose rayon producers faced lawsuits for negligent environmental pollution . Emissions abatement technologies had been consistently used. Carbon-bed recovery , for instance, which reduces emissions by about 90%, was used in Europe, but not in the US, by Courtaulds. Pollution control and worker safety started to become cost-limiting factors in production. Courtaulds Courtaulds

Courtaulds' activities in continental Europe consisted in a wholly owned, one-factory viscose fibre business employing some 3,000 people in France, a 50% share in a similar business in Germany (of which the other 50% was owned by VGF, the major competitor), and a minority shareholding which controlled 20% of the voting capital in
2485-578: The Contessa lingerie chain and McIlroys had been sold by 1995. In 2000, the American-based Sara Lee acquired Courtaulds Textiles in a hostile takeover for £150million. "Courtaulds Textile" remained as a division of Sara Lee, unlike the chemical merger, which saw "Courtaulds" disappear into Akzo Nobel . In the early 2000s, many jobs and factories were eliminated, especially in the UK, where manufacturing costs were higher. Marks and Spencer

U.S. President Lyndon B. Johnson enacted the Flammable Fabrics Act Amendment on December 14, 1967. Rayon Rayon production involves solubilizing cellulose to allow turning
2627-593: The Italian firm Snia Viscosa, also primarily a viscose fibre producer. This activity expanded until the 1960s, when these products were replaced by newer developments. In 1964 Courtaulds acquired Fine Spinners and Doublers for £14 million and the Lancashire Cotton Corporation for £22 million. Carbon disulfide , used in rayon production, increases the risk of heart attacks and strokes in rayon workers (among other health risks, some of them known since
2698-487: The Lyocell process became Lenzing property after the demise of Courtaulds Plc in 1998. The lyocell process does not use carbon disulfide. By the late 1980s, the manufacture of clothing was quickly moving to South East Asia and China . Courtaulds had closed many of its UK factories and moved production to new Asian sites. Further, its main profit was coming from its fibre and chemicals businesses, which were being held back by
2769-533: The Tencel division with other fibre divisions under the Acordis banner, then sold them off to private equity ( CVC Capital Partners ). In 2000, CVC sold the Tencel division to Lenzing AG , who combined it with their "Lenzing Lyocell" business, but maintained the brand name Tencel. At this time "Tencel" production was at 80,000 tonnes/year. In September 2000, Courtaulds Fibers Inc. was found guilty of negligence for polluting
2840-566: The US in 1910. The name "rayon" was adopted in 1924 , with "viscose" being used for the viscous organic liquid used to make both rayon and cellophane . In Europe, though, the fabric itself became known as "viscose", which has been ruled an acceptable alternative term for rayon by the US Federal Trade Commission (FTC). Rayon was produced only as a filament fiber until the 1930s, when methods were developed to utilize "broken waste rayon" as staple fiber. Manufacturers' search for
2911-459: The addition of delustering pigments cuts down on this natural brightness. The physical properties of rayon remained unchanged until the development of high-tenacity rayon in the 1940s. Further research and development led to high-wet-modulus rayon (HWM rayon) in the 1950s. Research in the UK was centred on the government-funded British Rayon Research Association . High-tenacity rayon is another modified version of viscose that has almost twice

The rate of depolymerization (ripening or maturing) depends on temperature and is affected by the presence of various inorganic additives, such as metal oxides and hydroxides. Air also affects the ripening process, since oxygen causes depolymerization. The alkali cellulose is then treated with carbon disulfide to form sodium cellulose xanthate : Rayon fiber
3124-498: The company closed a viscose plant in Calais , France, allowing its other plants to boost output to 93% capacity, compared with an industry average of 75%. The share price doubled in the first three years following the demerger. CEO Sipko Huismans had focused the company on rationalisation and cost cutting, saying "We have to cut costs. We can't count on sales growth to pay us more or to allow us to buy more of our favorite things." In 1993

Seeking to expand its business, specifically in Asia-Pacific, Courtaulds plc delivered part of its development in joint ventures, particularly with Akzo Nobel . It sought to merge with Akzo-Nobel, which the EU approved subject to the sale of Courtauld's aerospace business. In 1998 it merged with competitor Akzo Nobel . The name "Courtaulds" disappeared. Akzo Nobel combined

Three common solubilization methods are: French scientist and industrialist Hilaire de Chardonnet (1838–1924) invented the first artificial textile fiber, artificial silk . Swiss chemist Matthias Eduard Schweizer (1818–1860) discovered that cellulose dissolved in tetraamminecopper dihydroxide . Max Fremery and Johann Urban developed a method to produce carbon fibers for use in light bulbs in 1897. Production of cuprammonium rayon for textiles started in 1899 in

In 1927–28 Courtaulds and Vereinigte Glanzstoff-Fabriken (VGF) gained control of the Italian rayon manufacturer SNIA Viscosa from Riccardo Gualino . A German director of VGF, Karl Scherer, replaced Gualino as head of
3763-401: The largest lyocell producer at 130,000 tonnes/year. Rayon is produced by dissolving cellulose, then converting this solution back to insoluble fibrous cellulose. Various processes have been developed for this regeneration. The most common methods for creating rayon are the cuprammonium method, the viscose method, and the lyocell process. The first two methods have been practiced for more than
3834-567: The largest producers of rayon in the world, and Asia Pacific Rayon (APR) of the country has an annual production capacity of 0.24 million tons. 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. Subsequent experiments have shown that wood-based fibres, like Lyocell, biodegrade much more readily than polyester. Silverfish —like
3905-468: The lyocell process for making cellulose fibers. As of 2018 , the lyocell process is not widely used, because it is still more expensive than the viscose process. 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

The scoring from the 2020 report scores all such manufacturers on a scale of 35, the highest scores having been achieved by Birla Cellulose (33) and Lenzing (30.5). Carbon disulfide is highly toxic . It is well documented to have seriously harmed the health of rayon workers in developed countries, and emissions may also harm
4047-466: The product. Viscose rayon was first produced in Coventry, England in 1905 by Courtaulds. Bemberg is a trade name for cuprammonium rayon developed by J. P. Bemberg . Bemberg performs much like viscose but has a smaller diameter and comes closest to silk in feel. Bemberg is now only produced in Japan. The fibers are finer than viscose rayon. Modal and Tencel are widely used forms of rayon produced by Lenzing AG . Tencel, generic name lyocell ,

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. Modal is a genericized trademark of Lenzing AG , used for (viscose) rayon which
4189-603: The textiles business. In 1990, Courtaulds plc demerged itself into two parts: In 1990, the company began pilot production of Tencel , a brand of lyocell rayon. The production of lyocell does not use carbon disulfide , but is more expensive than viscose rayon. In January 1993, the Tencel plant in Mobile, Alabama , US reached full production levels of 20,000 tons per year, by which time Courtaulds had spent £100 million and 10 years on Tencel development. Tencel revenues for 1993 were estimated as likely to be £50 million. In 1991,
