[51], Retting can also be done in a plastic trash can or any type of water-tight container of wood, concrete, earthenware, or plastic. An exception is a type of yellow flax called solin (trade name "Linola"),[21] which has a completely different oil profile and is very low in omega-3s (alpha-linolenic acid (ALA), specifically). Cotton. Flax fiber is extracted from the bast beneath the surface of the stem of the flax plant. It's a natural fibre! Dressing consists of three steps: breaking, scutching, and heckling. [26] If packed immediately without exposure to air and light, milled flaxseed is stable against excessive oxidation when stored for nine months at room temperature,[27] and under warehouse conditions, for 20 months at ambient temperatures. Flax fiber is a raw material used in the high-quality paper industry for the use of printed banknotes, laboratory paper (blotting and filter), rolling paper for cigarettes, and tea bags.[34]. [14] As the Roman Empire declined, so did flax production. It generally takes place in a shallow pool which will warm up dramatically in the sun; the process may take from a few days to a few weeks. (a) flax Flax is a vegetable fibre, and all vegetable fibres have cellulose as their structural material. It is an edible oil obtained by expeller pressing and sometimes followed by solvent extraction. Flax also represents Northern Ireland on the badge of the Supreme Court of the United Kingdom and on various logos associated with it. The use of flax fibers dates back tens of thousands of years; linen, a refined textile made from flax fibers, was worn widely by Sumerian priests more than 4,000 years ago. It can only be added at low percentages due to the high fat content, which is unhealthy for ruminants. The leaves are glaucous green, slender lanceolate, 20–40 mm long, and 3 mm broad. The amount of weeds in the straw affects its marketability, and this, coupled with market prices, determines whether the farmer chooses to harvest the flax straw. Ring in the new year with a Britannica Membership. [54] Laboratories are certified to test for the presence of 'Triffid' at a level of one seed in 10,000.[55]. In a 100-gram serving, flaxseed contains high levels (> 19% of the Daily Value, DV) of protein, dietary fiber, several B vitamins, and dietary minerals. When wrapped around a finger, the inner woody part springs away from the fibers. Flaxseed is the name given to the seeds of the plant Linum usitatissimum. Textiles made from flax are known in Western countries as linen, and are traditionally used for bed sheets, underclothes, and table linen. The soils most suitable for flax, besides the alluvial kind, are deep loams containing a large proportion of organic matter. Three phenolic glucosides — secoisolariciresinol diglucoside, p-coumaric acid glucoside, and ferulic acid glucoside — are present in commercial breads containing flaxseed. [31] Sheep feeding on low quality forage are able to eat a large amount of linseed meal, up to 40% in one test, with positive consequences. Flax processing is divided into two parts: the first part is generally done by the farmer, to bring the flax fiber into a fit state for general or common purposes. Two ways are used to harvest flax fiber, one involving mechanized equipment (combines), and a second method, more manual and targeting maximum fiber length. Heuzé V., Tran G., Nozière P., Lessire M., Lebas F., 2017. Its diameter varies from 40 to 80 μm. Pond-retted flax is traditionally considered of lower quality, possibly because the product can become dirty, and is easily over-retted, damaging the fiber. Linseed meal. [10] In China and India, domesticated flax was cultivated at least 5,000 years ago. [28], After crushing the seeds to extract linseed oil, the resultant linseed meal is a protein-rich feed for ruminants, rabbits, and fish. Question 63. The plant species is known only as a cultivated plant,[2] and appears to have been domesticated just once from the wild species Linum bienne, called pale flax.

[8] Evidence exists of a domesticated oilseed flax with increased seed-size from Tell Ramad in Syria[8] and flax fabric fragments from Çatalhöyük in Turkey[9] by circa 9,000 years ago. [17], Flax is grown for its seeds, which can be ground into a meal or turned into linseed oil, a product used as a nutritional supplement and as an ingredient in many wood-finishing products. [43], Flaxseed and its oil have repeatedly been demonstrated to be nontoxic and are generally recognized as safe for human consumption. Textiles made from flax are known in Western countries as linen, and are traditionally used for bed sheets, underclothes, and table linen. Heavy clays are unsuitable, as are soils of a gravelly or dry sandy nature. The flax plant produces the flax fibres used to make linen. It is cultivated as a food and fiber crop in cooler regions of the world. [5][6][7] Humans first domesticated flax in the Fertile Crescent region. Cotton is the most common natural fibers in our daily life. A fiber cross section has 3 to 6 ultimate cells. Natural fibres are bio-based materials manufactured from materials such as wood, cotton, flax, kenaf, and hemp. Flax is much stiffer due to the cement that holds the fiber bundle together. Pond retting is the fastest. Courier Dover Publications, p. 22. (c) Terylene is a synthetic fibre but flax is a natural fibre. The flowers are pure pale blue, 15–25 mm in diameter, with five petals. [35] New methods of processing flax have led to renewed interest in the use of flax as an industrial fiber. Flaxseed, both whole and ground, is rich in soluble fiber and other health-boosting nutrients. Linola was developed in Australia and introduced in the 1990s with less omega-3, specifically to serve as fodder. [44] Like many common foods, flax contains small amounts of cyanogenic glycoside,[45] which is nontoxic when consumed in typical amounts, but may be toxic when consumed in large quantities as with staple foods such as cassava. The Sumerians: Their history, culture and character, Learn how and when to remove this template message, laboratory paper (blotting and filter), rolling paper, "The Plant List: A Working List of All Plant Species", "These Vintage Threads Are 30,000 Years Old", CRS Report for Congress: Agriculture: A Glossary of Terms, Programs, and Laws, 2005 Edition - Order Code 97-905, "Pigments through the Ages - Renaissance and Baroque (1400-1600)", "Effect of processing flax in beef feedlot diets on performance, carcass characteristics, and trained sensory panel ratings", "Full Report (All Nutrients): 12220, Seeds, flaxseed per 100 g", "Flax and flaxseed oil: an ancient medicine & modern functional food", "Does ground flaxseed have more health benefits than whole flaxseed? Under conditions similar to those found in commercial bakeries, trained sensory panelists could not detect differences between bread made with freshly ground flaxseed and bread made with flaxseed that had been milled four months earlier and stored at room temperature. This plant really loves CO 2.With a little help of the sun, flax plants on one hectare absorb more than a 3,7 metric tons of carbon dioxide and convert it into oxygen. If the plants are still green, the seed will not be useful, and the fiber will be underdeveloped. As a result of alternating rain and the sun, an enzymatic action degrades the pectins which bind fibers to the straw. Flax linen is a natural fiber, know for its vibration dampening properties. Scum collects at the top, and an odor is given off the same as in pond retting. Its use in fish feeds is limited. The second part of the process brings the flax into a state for the very finest purposes, such as lace, cambric, damask, and very fine linen. [36][37] Flaxseed oil contains 53% 18:3 omega-3 fatty acids (mostly ALA) and 13% 18:2 omega-6 fatty acids. [19][31], Flax straw left over from the harvesting of oilseed is not very nutritious; it is tough and indigestible, and is not recommended to use as ruminant fodder, although it may be used as bedding or baled as windbreaks.[31]. Feedipedia, a programme by INRA, CIRAD, AFZ and FAO. In early versions of the Sleeping Beauty tale, such as "Sun, Moon, and Talia" by Giambattista Basile, the princess pricks her finger, not on a spindle, but on a sliver of flax, which later is sucked out by her children conceived as she sleeps. At this point, straw, or coarse outer stem (cortex and epidermis), is still remaining. Flax fibre is made from plant Linum usitatissimum. [29] The high omega-3 fatty acid (ALA) content of linseed meal "softens" milk, eggs or meat, which means it causes a higher unsaturated fat content and thus lowers its storage time. In 2018, world production of flax (linseed) was 3.2 million tonnes, led by Kazakhstan with 29% of the total. [38][39] Flaxseeds are especially rich in thiamine, magnesium, potassium, and phosphorus (DVs above 90%). The plants are left in the field for field retting. Many health conditions, including constipation, irritable bowel syndrome and … Most natural fiber is of limited length, commonly a few millimeters to several centimeters. Although it may increase the omega-3 content in eggs and meat, it is also an inferior and potentially toxic feed for poultry, although it can be used in small amounts. [33], The best grades are used for fabrics such as damasks, lace, and sheeting. [29][30] In the US, flax-based feed for ruminants is often somewhat more expensive than other feeds on a nutrient basis. Routledge, p. 124, Buchanan R. (2012) "A Weaver's Garden: Growing Plants for Natural Dyes and Fibers". Several other species in the genus Linum are similar in appearance to L. usitatissimum, cultivated flax, including some that have similar blue flowers, and others with white, yellow, or red flowers. The fruit is a round, dry capsule 5–9 mm in diameter, containing several glossy brown seeds shaped like an apple pip, 4–7 mm long. A 100-gram portion of ground flaxseed supplies about 534 calories (2,230 kJ), 41 g of fat, 28 g of fiber, and 20 g of protein. The bases of the plants begin to turn yellow. Common flax is the national flower of Belarus. Flax is a difficult fiber to spin in blends as it is coarser than cotton and most of the artificial or synthetic fibers (between 4 to 8,5 Micronaire), it is quite short (between 14 and 20 mm, and cut combed tops can go up to 25 mm) and it has a weak fiber adhesion. (e) Fabrics are made first by spinning the fibre to make yarn and then weaving or knitting the yarn. Which of the following is not a synthetic fibre? Using with Carbon Fiber Ekoa ® is engineered to be compatible with carbon fiber. It is also known as common flax or linseed. Flax straw that is not of sufficient quality for fiber uses can be baled to build shelters for farm animals, or sold as biofuel, or removed from the field in the spring.[50]. To remove this, the flax is "broken", the straw is broken up into small, short bits, while the actual fiber is left unharmed. A common feature of natural fibers is a much higher variability of mechanical properties. As opposed to natural fibres, filament production in synthetic fibres is brought about by the spinning process which is either wet or dry. A distaff is a tool which keeps the fibers separated and properly aligned during spinning. This form of retting also produces quite an odor. It might also act as a substitute to tallow in increasing marbling. [49] Other major producers were Canada, Russia, and China (table). Flax for fiber production is usually harvested by a specialized flax harvester. They began growing fibre flax in 2011 after hosting a natural fibre symposium on their farm that year, which got them interested in how fibre flax might … It can be retted in a pond, stream, field, or tank. When dried sufficiently, a combine then harvests the seeds similar to wheat or oat harvesting. Flax fiber is soft, lustrous, and flexible; bundles of fiber have the appearance of blonde hair, hence the description "flaxen" hair. This second part is performed by a refining machine. Wool … This is a natural plant that generally has a more eco friendly growing and harvesting stage than say for example cotton, or compared to the making a synthetic fibre like polyester. The mature plant can also be cut with mowing equipment, similar to hay harvesting, and raked into windrows. Both pond and stream retting were traditionally used less because they pollute the waters used for the process. Flax fiber-reinforced composites have the potential for wide usage in sport and maritime industries, and as automotive accessories. China, India, Egypt, Peru, Brazil, … [57] Canadian flaxseed cultivars were reconstituted with 'Triffid'-free seed used to plant the 2014 crop. The rubber belts then pull the whole plant out of the ground with the roots so the whole length of the plant fiber can be used. Flax grown for seed is allowed to mature until the seed capsules are yellow and just starting to split; it is then harvested in various ways. What is the composition of flax? Introduction to the use of flax fibres as a composite material reinforcement. It is used for the protection of silkworms. Linen is a Natural material made from the fiber of flax. In addition to referring to the plant itself, the word "flax" may refer to the unspun fibers of the flax plant. The stems are then pulled through "hackles", which act like combs to remove the straw and some shorter fibers out of the long fiber. The plant species is known only as a cultivated plant, and appear… Linen ( / ˈlɪnən /) is a textile made from the fibers of the flax plant. Farming flax requires few fertilizers or pesticides. [19][29] One study found that feeding flax seeds may increase omega-3 content in beef, while another found no differences. Resembles flax; more coarse and stiffer Some of the straw is scraped from the fibers in the scutching process, and finally, the fiber is pulled through heckles to remove the last bits of straw. [24] Whole flaxseeds are chemically stable, but ground flaxseed meal, because of oxidation, may go rancid when left exposed to air at room temperature in as little as one week. Silk is made from the silkworm.. Silkworm spins a cocoon of thread around itself. PHI Learning Private Limited, New Delhi, p. 76, Wisseman S. (2013) "Ancient Technologies and Archaeological Materials". [11], Flax was cultivated extensively in ancient Egypt, where the temple walls had paintings of flowering flax, and mummies were embalmed using linen. [15] In North America, colonists introduced flax, and it flourished there,[16] but by the early 20th century, cheap cotton and rising farm wages had caused production of flax to become concentrated in northern Russia, which came to provide 90% of the world's output. Flax fiber is 10–100 cm in length. Manufactured and Synthetic fibers (can have generic and trade names) ... Staple length is important as it relates to fiber fineness and tensile strength. Flax fibers, along with a number of other natural fibers, are being considered as an environmentally friendly alternative of synthetic fibers in fiber-reinforced polymer composites. If the flax straw is not harvested, typically, it is burned, since the stalks are quite tough and decompose slowly (i.e., not in a single season). In September 2009, Canadian flax exports reportedly had been contaminated by a deregistered genetically modified cultivar called 'Triffid' that had food and feed safety approval in Canada and the U.S.,[54][55] however, Canadian growers and the Flax Council of Canada raised concerns about the marketability of this cultivar in Europe where a zero tolerance policy exists regarding unapproved genetically modified organisms. Fiber bundle consists of many individual fibers of about 25 to 40 mm in length (fiber ultimate) which are cemented together by a mixture of lignin, pectin and hemicelluloses. (2003) "The Oxford Encyclopedia of Economic History, Volume 1" Oxford University Press, p.303. Flax contains hundreds of times more lignans than other plant foods.[38]. ", "Meta-analysis of the effects of flaxseed interventions on blood lipids", "The effect of flaxseed supplementation on body weight and body composition: a systematic review and meta-analysis of 45 randomized placebo-controlled trials", "Flaxseed consumption may reduce blood pressure: a systematic review and meta-analysis of controlled trials", "Effect of Flaxseed Intervention on Inflammatory Marker C-Reactive Protein: A Systematic Review and Meta-Analysis of Randomized Controlled Trials", "GRAS Petition by Flax Canada, Agency Response Letter GRAS Notice No. Flax is harvested for fiber production after about 100 days, or a month after the plants flower and two weeks after the seed capsules form. [4] Some of these are perennial plants, unlike L. usitatissimum, which is an annual plant. The flax plant turned over and is gripped by rubber belts roughly 20–25 cm (8-10") above ground, to avoid getting grasses and weeds in the flax. It is cultivated as a food and fiber crop in cooler regions of the world. Threshing is the process of removing the seeds from the rest of the plant. Although brown flaxseed varieties may be consumed as readily as the yellow ones, and have been for thousands of years, its better-known uses are in paints, for fiber, and for cattle feed. Stream retting is similar to pool retting, but the flax is submerged in bundles in a stream or river. 1. Flax craves carbon dioxide. Europe and North America both depended on flax for plant-based cloth until the 19th century, when cotton overtook flax as the most common plant for making rag-based paper. Formed into windrows from the harvesting process, the straw often clogs up tillage and planting equipment. If the water temperature is kept at 80 Â°F (27 Â°C), the retting process under these conditions takes 4 or 5 days. Dyed flax fibers have been found that date to 30,000 BC. [19] It is also often used as feed for swine and poultry, and has also been used in horse concentrate and dog food. A. nylon B. flax C. acrylic D. polyester Answer: B. flax Flax is a blue-flowered herbaceous plant that is cultivated for its seed and for textile fiber made from its stalks. The meal is an adequate and traditional source of protein for rabbits at 8-10%. Flax fibers taken from the stem of the plant are two to three times as strong as cotton fibers. Though flax has lost some of its value as a commercial fibre crop owing to the availability of synthetic fibres, flaxseed has grown in popularity as a health food, and flax remains economically significant in a number of countries around the world, including China, Russia, and Canada. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. In addition to referring to the plant itself, the word "flax" may refer to the unspun fibers of the flax plant. 0 0 1 ... , or made from synthetic fibres or combinations of natural fibres and synthetic fibres. [32] Industrial-scale flax fiber processing existed in antiquity. Length: Length is the most important factor for assessing the value of a fiber. Nanofiber refers to a synthetic/inorganic fiber which is fine nano dimension. [13] Phoenicians traded Egyptian linen throughout the Mediterranean and the Romans used it for their sails. The farmers turn over the straw during retting to evenly rett the stalks. Flax, also known as common flax or linseed, is a flowering plant, Linum usitatissimum, in the family Linaceae. [41] Another meta-analysis has shown that consumption of flaxseed for more than 12 weeks produced small reductions in systolic blood pressure and diastolic blood pressure. Solvent-processed flaxseed oil has been used for many centuries as a drying oil in painting and varnishing.[23]. One study of research published between 1990 and 2008 showed that consuming flaxseed or its derivatives may reduce total and LDL-cholesterol in the blood, with greater benefits in women and those with high cholesterol. Before the flax fibers can be spun into linen, they must be separated from the rest of the stalk. After this, the flax is allowed to dry, the seeds are removed, and it is then retted. Cultivated flax plants grow to 1.2 m (3 ft 11 in) tall, with slender stems. Flax mills for spinning flaxen yarn were invented by John Kendrew and Thomas Porthouse of Darlington, England, in 1787. Thread is produced using the small wheel often called a flax wheel. Flax is grown on the Canadian prairies for linseed oil, which is used as a drying oil in paints and varnishes and in products such as linoleum and printing inks. But with laws designed to publicize the hygiene of linen textiles and the health of linseed oil, Charlemagne revived the crop in the eighth century CE. Flax seeds may be useful as a part of a weight loss diet. When the straw is retted and sufficiently dry, it is rolled up. Flax is also grown as an ornamental plant in gardens. [29] Compared to oilseed meal from crucifers it measures as having lower nutrient values,[19] however, good results are obtained in cattle, perhaps due to the mucilage, which may aid in slowing digestion and thus allowing more time to absorb nutrients. Coarser grades are used for the manufacturing of twine and rope, and historically, for canvas and webbing equipment. [3] The plants called "flax" in New Zealand are, by contrast, members of the genus Phormium. [22], Flaxseeds produce a vegetable oil known as flaxseed oil or linseed oil, which is one of the oldest commercial oils. It is then stored by farmers before extracting the fibers. Species of plant used as a food and fibre crop, Barber E. (1991) "Prehistoric Textiles: The Development of Cloth in the Neolithic and Bronze Ages with Special Reference to the Aegean". Within eight weeks of sowing, the plant can reach 10–15 cm (3.9–5.9 in) in height, reaching 70–80 cm (28–31 in) within 50 days. [19], Linseed meal is added to cattle feed as a protein supplement. When the retting is complete, the bundles of flax feel soft and slimy, and quite a few fibers are standing out from the stalks. Flax and jute are the natural fibres obtained from plants. Moreover, flax fibers are used to make linen. Separating the usable flax fibers from other components requires pulling the stems through a hackle and/or beating the plants to break them. Since flax is such a long fiber, special care must be given before spinning to keep it from tangling. Longer fiber - finer and stronger Ex of long staple) Pima cotton, Egyptian cotton ... similar to flax very strong fiber, especially when wet. Flax stem, fiber, yarn and woven and knitted linen textiles. The specific epithet, usitatissimum, means "most useful".[18]. Flax fibre is characterised by high rigidity and vibration absorption and low density (1.4 p (g/cm³)) compared to glass fibre (2.54 p (g/cm³)) and other composite fibres. Linen is very strong and absorbent and dries faster than cotton. Scutching scrapes the outer straw from the fiber. The earliest evidence of humans using wild flax as a textile comes from the present-day Republic of Georgia, where spun, dyed, and knotted wild flax fibers found in Dzudzuana Cave date to the Upper Paleolithic, 30 thousand years ago. Dependent upon climatic conditions, characteristics of the sown flax and fields, the flax remains on the ground between two weeks and two months for retting. Consequently, such fibres have long been used for textiles and rope making. [15] Eventually, Flanders became the major center of the European linen industry in the Middle Ages. Usually built on the same machine base as a combine, but instead of the cutting head it has a flax puller. [48] Flax is often found growing just above the waterline in cranberry bogs. Its oil is known as linseed oil. In natural fibres, the length of the fibres is given whereas, in synthetic fibres, the length of the fibre is controlled by man. Cellulose polymer; rich in fat, protein and dietary fiber Flax is the emblem of Northern Ireland and displayed by the Northern Ireland Assembly. Silk is the exception, being formed as filament, which may be 500-2000 meter in length. This is not an issue in meal cake due to the processing temperature during oil extraction. The raw materials used to manufacture natural-fibre composites are environment-friendly and have the potential to replace synthetic fibres over the coming years. Flax fiber is obtained from the inner bark of the stem of a plant grown in temperate and subtropical regions of the world. Dressing the flax is the process of removing the straw from the fibers. [19], Flaxseeds occur in two basic varieties/colors: brown or yellow (golden linseeds). [56] Subsequently, deregistered in 2010 and never grown commercially in Canada or the U.S.,[57] 'Triffid' stores were destroyed, but future exports and further tests at the University of Saskatchewan proved that 'Triffid' persisted among flax crops, possibly affecting future crops. [52][53], Flax fiber in different forms, before and after processing. Princeton University Press, p.12, Cullis C. (2007) "Oilseeds" Springer, p. 275, Sekhri S. (2011) "Textbook of Fabric Science: Fundamentals to Finishing". According to some reports, it uses less water and uses less energy than the production of cotton. Use of the crop steadily spread, reaching as far as Switzerland and Germany by 5,000 years ago. The breaking breaks up the straw. This generally takes two or three weeks longer than pond retting, but the end product is less likely to be dirty, does not smell as bad, and because the water is cooler, is less likely to be over-retted. Its oil is known as linseed oil. Flax is very resistant, absorbs humidity well, and never tends to lose its shape.Flax has long tough stem fibers. [46] Typical concentrations (for example, 0.48% in a sample of defatted dehusked flaxseed meal) can be removed by special processing.[47]. The first step in this process is retting, which is the process of rotting away the inner stalk, leaving the outer parts intact. It consists of placing the flax in a pool of water which will not evaporate. (d) The common name of coconut fibre is coir. It is considered an inferior protein supplement for swine because of its fibre, the vitamin antagonist, the high omega-3 content and its low lysine content, and can only be used in small amounts in the feed. A Bronze Age factory dedicated to flax processing was discovered in Euonymeia, Greece. The plant is pulled up with the roots (not cut), so as to increase the fiber length. [36][37] Ten grams of flaxseed contains one gram of water-soluble fiber (which lowers blood cholesterol) and three grams of insoluble fiber (which helps prevent constipation).
