The fiber's extraction and cleaning are expensive, chiefly because of the several steps—involving scraping, pounding, heating, washing, or exposure to chemicals. Like flax, jute, and hemp, ramie is considered a bast fiber crop, meaning that the usable portion of … Washing of fibre from stems immediately after decortications has been shown to remove water soluble gums which reduce the dry weight of the fibre by 8%. By Jute" is the name of the plant or fiber used to make burlap, hessian or gunny cloth. As with all fabrics, handling gently prolongs the life of the fabric. What is Ramie? Interested in Innovative ideas, First harvesting can be done after 17 days of planting and followed by 45-60 days for the succeeding harvests. In order that the fiber may lend itself more readily to the subsequent manufacturing operations, it is usually treated with an oily preparation composed in most cases of water, glycerine, wax and soap, when it is thoroughly softened, ramie is ready for processing. Ramie is also resistant to chemicals and mildew. This process is called decortication. But it is only in comparatively modern times that the production of ramie fabric has become established on a commercial scale. In Vietnam, ramie leaves are called "cây lá gai," which is a main ingredient in making "bánh gai" or "bánh ít lá gai," a Vietnamese glutinous rice cake. What is Ramiè? . The process of removal of gum from the fibre is known as degumming. Shorter fibers and waste are used in paper manufacture. Colour, strength, softness, length, fibre separation and defects (major, minor). tenacissima), also referred as Chinese grass or white ramie, is a member of the Urticaceae family and principally produced in China, Japan, and several other South Asian countries. As a result of degumming, the gummy matter will be removed and the fibre weight reduces by 22-25%. Ramie is also readily dyed but hard to spin. World production of ramie fiber (ton) 2. This produces coarser count yarn but much less labour is required. Ramie is also used as an ornamental plant in eastern Asia. Decortication is to be done immediately after harvest and therefore, a harvesting schedule is planned in relation to the decortications capacity of the machines used. It is produced from flowering plants in the genus Corchorus, which is in the mallow family Malvaceae.The primary source of the fiber is Corchorus olitorius, but it is considered inferior to Corchorus capsularis. " Ramie is one of the oldest textile fibers. For the 2010 Prius, Toyota began using a new range of plant-derived ecological bioplastics made from the cellulose in wood or grass instead of petroleum. During grading, the following parameters are to be checked. If this is not done while the plants are still fresh, the plants dry out and the bark will be difficult to remove. In Europe, Brazil and the Philippines, some modifications are made. Normally, ramie is harvested twice or thrice annually. Ramie is originated from China, India, and Indonesia and has been used thousands of years, making it one of the oldest fiber crops. It is not as durable as other fibers, so is usually used as a blend with other fibers such as cotton or wool. Its luster is fine and silky and it creates good appearance in fabric. Since then, production has steadily declined as a result of competition from alternative crops, such as soybeans and synthetic fibers. Ramie is one of the oldest fiber crops, having been used for at least six thousand years, and is principally used for fabric production.It is a bast fiber, and the part used is the bark of the vegetative stalks.Ramie is normally harvested two to three times a year but under good growing conditions can be harvested up to six times per year. Aside from its strength, ramie fiber does not stretch or shrink. It was used in mummy cloths in Egypt during the period 5000 - 3000 BC, and has been grown in China for many centuries. Ramie is one of the oldest fiber crops, having been used for at least 6,000 years, and is principally used for fabric production. One of the two principal crops used is ramie. Chemical processing is required for processing ramie. So, it is always better to remove the gum content of ramie fibre before going for the processing of the fibre. [3] Stems are harvested by cutting just above the lateral roots or by bending the stem. The ribbons of partially separated but not yet degummed fibre, are known as “China grass” and it is in this form that ramie is normally exported from China to European and other markets. The medium-length fibre is either spun on its own, or spun together with the short fibre and any waste which is obtained during the dressing of the long fibre. It is a durable fiber. It is a bast fiber, and the fiber used for textiles comes from the inner bark (phloem) of the vegetative stalks and not the woody stem or outer bark. If the stems are allowed to become too mature, lignification takes place. It's one of the oldest vegetable fibers, having been used for thousands of years for all sorts of fabrics — including ancient Egyptian mummy wraps!. The blended yarns have good scope in the areas like home furnishing, upholstery and industrial fabrics. From the figure it is observed that after the chemical treatment, the fibres are found to be clean. Ramie is also occasionally used in the construction of high performance rowing oar shafts. Ramie is one of the oldest fiber crops, having been used for at least 6,000 years, and is principally used for fabric production. Dept. It is a bast fiber, and the fiber used for textiles comes from the inner bark (phloem) of the vegetative stalks and not the woody stem or outer bark. Some have been in use for a long while, but they all have drawbacks for commercial big scale production. Only a small percentage of the ramie produced is available on the international market. In another work, degummed ramie fibre of cut staple length 20 cm was processed in flax carding system and subsequently blended with jute fibre during drawing stage. • NP-PL enhanced RS production from fruit and vegetables peels at 50 and 90 °C. For the Irish hurler, see. A number of small machines have been designed in various countries with the objective of extracting bast fibre from the green stems of jute and similar fibre plants and thus eliminating the need of retting. After the fibre has been submitted to the degumming action, it is thoroughly washed and dried. The ramie plant is a hardy perennial belonging to the Urticaceae or … Completed B.Sc. Use of decorticators in the field saves the cost of transporting unwanted plant material to soil. You have entered an incorrect email address! It is the strongest fiber crown known. Harvesting is done either by manually or by using mechanical harvesters. The Ramie plant is mainly used for fabric production. Decortication should be completed on the day of harvest and if there are some left over, they should be kept moist by sprinkling water till decortications is done on the following day. It is essential to remove the excess of alkali by acetic acid treatment after chemical degumming, otherwise the fibre strength will be reduced. After degumming the cellulose content of the fibres are raised above 95%. It acts as an inhibitor for water and other chemicals to enter inside the fibre. Ramie is a fiber made from a plant of the same name – a member of the nettle family. [3] Unlike other bast crops, ramie requires chemical processing to de-gum the fiber. Ramie is normally harvested two to three times a year, but under good growing conditions can be harvested up to six times per year. Ramie is one of the oldest fiber crops, having been used for at least 6,000 years, and is principally used for fabric production. China leads in the production of ramie and exports mainly to Japan and Europe. Ramie is one of the oldest fiber crops, having been used for at least 6,000 years, and is principally used for fabric production. Unlike other bast crops, ramie requires chemical processing to de-gum the fiber. Global Ramie Fiber Market analyzes the impact followed by restraints and opportunities and projected developments (2020-2026) Global Ramie Fiber Market industry analysis and forecast 2020–2026 delivering key insights and providing a competitive advantage to clients through a detailed report.The rapidly changing market scenario and initial and future assessment of the impact is … Some or all are needed to separate the raw fiber from the adhesive gums or resins. However, the process of separating the fiber from the plant stem’s bark and woody portions requires significant hand labor or mechanized processing. Other articles where Ramie fabric is discussed: ramie: Ramie fabric was used in ancient Egypt and was known in Europe during the Middle Ages. Cambridge University Press. Textile, 7 (1): 1-9, 2017. Attempts have been made by various researchers to spin ramie in blends with jute, silk, viscose and polyester fibres using jute and woollen spinning systems. (Brittain Bragunier), 1899-Publication date 1940 Topics Ramie, Fiber plants, ramie, plant fibers, natural history, plant cultural practices, harvesting, processing technology, crop yield, plant characteristics, economic outlook and situation [1] The word "ramie" is derived from the Malay word rami.[2]. 10.1002/(SICI)1439-2054(20000301)276:1<1::AID-MAME1>3.0.CO;2-W, https://en.wikipedia.org/w/index.php?title=Ramie&oldid=993929429, Articles with unsourced statements from August 2015, Wikipedia articles incorporating a citation from the 1911 Encyclopaedia Britannica with Wikisource reference, Taxonbars with automatically added basionyms, Creative Commons Attribution-ShareAlike License, This page was last edited on 13 December 2020, at 06:19. Generally two methods of grading are adopted. In some of the reported works, blending of 10-15% raw or ramie partially degummed ramie with jute helps to spin good quality yarns of finer count in the range of 100-105 tex. It exhibits even greater strength when wet. Ramie fibers are exceptionally long, lustrous, durable, soft, and stronger than cotton. Various aspects such as Ramie Fiber import or export, price, gross margin, consumption, and cost are also analyzed. Methods of spinning ramie may vary, in different countries and mills and are determined to a large extent by the type of spinning system available in a particular mill. Today, China is a pioneer in ramie fiber production and other main producer countries are Taiwan, Korea, the Philippines and Brazil. Long staple fibres can be used for spinning, where as short fibres are using for the manufacture of papers, composites, non woven and other products. [3], Ramie has been grown in China for many centuries, and farmers in ancient China are known to have used the fiber to weave clothing. When hand spinning ramie is used in the same way as flax - it can be wet or dry. The decorticator and decorticated ramie fibre . China is considered the main producer of ramie fiber. The ramie fiber (Boehmeria nivea (L.) Gaud, Boehmeria nivea var. Other producers include Japan, Taiwan, the Philippines, and Brazil. It is also made into fabrics for household furnishings (upholstery, canvas) and clothing, frequently in blends with other textile fibers (for instance when used in a mixture with wool, shrinkage is reported to be greatly reduced when compared with pure wool). Its durability is high. The bast of ramie cannot be removed from the woody tissue in which it is embedded by a simple retting process such as is used for flax, hemp and jute. The ribbons of ramie, on their arrival at the factory, are greenish yellow to yellowish-white strips. Products that are 100% ramie shouldn't require any special care. A second type, known as green ramie or rhea, is believed to have originated in the Malay Peninsula[citation needed]. Ramie fiber is collected from the bark of the vegetable stalks. It does not dye as well as cotton. It was used in mummy cloths in Egypt during the period 5000-3000 BC and has been grown in China for many centuries. The extracted fibres contain approximately 25-30% gum. The main producers of ramie today are China, Brazil, Philippines, India, South Korea and Thailand. Either the fibre is imperfectly cleaned so that it can only be put to use for limited local purposes, or the output is much too low, or there too much wastage of fibre during the process of decortications. Ramie is normally harvested two to three times a year, but under good growing conditions can be harvested up to six times per year. Taiwan's aboriginal people have used ramie for millennia in fabric production and ramie is still used to create traditional garb which is worn in the festivals which have not been banned (mostly related to decapitation and stabbing enemy captives). There is no international grading system is available for grading of ramie fibre and the grading is done as per the standards developed by the ramie producing countries. After three passages of successive drawing, the sliver was processed through jute roving machine and finally spun in to a yarn of 84 tex. One of the oldest crops ever used for fiber, Ramie has been around for a minimum of 6,000 years. The existing jute grading system can also be adoptable in the case of ramie. These glutinous rice powder dumplings are known as "ban (粄)" in Hakka or "Cha Kwo (茶棵)" in Cantonese, similar to another Southeast Asian delicacy otherwise known as Kuih. Its single fiber is long, the strength is the largest, moisture absorption and moisture dispersing are quick, heat conduction performance is good, white after gluing has mermerization, can be pure spinning, and can also be mixed with cotton, silk, wool, chemical fiber, etc.. On gum removal, the crystallites increase in width but deteriorate with regard to their alignment along the fibre axis. It is similar to linen in absorbency, density, and microscopic appearance. Ramie (pronounced: /ˈreɪmi/, RAY-mee; from Malay rami) is a flowering plant in the nettle family Urticaceae, native to eastern Asia. Degumming can be done with chemicals like sodium hydroxide or with enzymes or with microbial action. "Ramie" . They may be used in this form for coarse products, but if ramie is to be spun into yarns suitable for fine fabrics, the first process in the mill is to degum the ribbons. • NP-PL enhanced the fiber tenacity and fineness. The quality of decortication and fibre recovery also depend largely on the efficiency of the operator as well as condition of the plants. Stalks becoming dry after harvest cannot be properly decorticated. During eighteenth and nineteenth centuries, ramie cultivation became established in many areas of the western world. [10] Only a small percentage of the ramie produced is available on the international market. The bark ribbon is then dried as quickly as possible, preventing bacteria and fungi from attacking it. The extracted fibrous material, after washing, should be immediately dried or degummed to prevent the development of mildew. In the Chinese Hakka community, ramie leaves are called "chu yap (苧葉)," which is a main ingredient in making pancake-like dumplings with glutinous rice powder, sugar and water. Kadolph SJ, Langford AL. Textiles (9th ed.). Mainly, it is used for the production of fiber. Korea also produce this fiber in small quantities Over the past years competition from other fibers, especially the synthetic fibers but also flax, has impacted the use of ramie fiber. The decorticated and chemically degummed fibres. Series: Circular (United States. The finest yarns are produced on the spun silk system developed by the Japanese, but this system is labour intensive. [5], Brazil began production in the late 1930s with production peaking in 1971. Ramie is one of the oldest fiber crops, having been used for at least 6,000 years, and is principally used for fabric production. The market prize of ramie fibre is determined by grading system. The pretreatment performance of three DESs, i.e., choline chloride-urea (CU), choline chloride-oxalic acid … Other producers include Japan, Taiwan, the … The fact that the fabric ramie, said and used in its production of fiber - one of the best materials of plant origin. Tensile strength of jute/ramie blended (50:50) yarn under normal dry and wet conditions were found to be better as compared to 100% jute yarn. Hons ( Horticulture ), This fiber was growing in china in the past. Second, the cortex is scraped to remove most of the outer bark, the parenchyma in the bast layer and some of the gums and pectins. [3], The fiber extraction occurs in three stages. Naturally white and glossy, fabrics made from ramie fibers have a beautiful, lustrous appearance. After harvesting, if the ribbons are not to be stripped from the stalks right away and the fibre extracted, the cut stems or ribbons should be dried as soon as possible, to prevent bacterial attack. The leaves give the cake its distinct color, flavor and fragrance. Encyclopædia Britannica (11th ed.). Unlike other bast crops, ramie requires chemical processing to de-gum the fiber. The ramie leaves are picked, cleaned and ground in mortar, mixed into a dough of glutinous rice powder, water and sugar, kneaded thoroughly and placed on palm-sized square- or circular-cut banana leaves and steamed. The best cleaned ribbons on arrival in the mill contain at least 10-15% of gummy matter, whereas the poorer qualities contain 20-30% and this must be extracted. The fibre is derived from the inner bast tissues of the stem. In the current scenario, there is no specialized spinning system in India is available for ramie and is spun in jute system. Normally, about 60% of the total weight of the degummed material will be long fibre. The ramie plant can be harvested three to five times each year and is considered a promising ecologically friendly fiber. It is a herbaceous perennial growing to 1.0–2.5 m (3 ft 3 in–8 ft 2 in) tall;[1] the leaves are heart-shaped, 7–15 cm (2.8–5.9 in) long and 6–12 cm (2.4–4.7 in) broad, and white on the underside with dense, small hairs—this gives it a silvery appearance; unlike stinging nettles, the hairs do not sting. This enables the core to be broken and the cortex can be stripped from the plant in situ. Save my name, email, and website in this browser for the next time I comment. It is a bast fiber, and the fiber used for textiles comes from the inner bark (phloem) of the vegetative stalks and not the woody stem or outer bark. The most significant factors involved in ramie degumming are the concentration of the chemicals, temperature, time and the methods employed to ensure that the degumming liquor penetrates to all parts of the ribbons. Delayed ramie harvesting will severely affect fiber quality and ramie production in the next season (Peng, 2009). It is a bast fiber, and the fiber used for textiles comes from the inner bark (phloem) of the vegetative stalks and not the woody stem or outer bark. Ramie Fabric Care. Ramie fiber is known especially for its ability to hold shape, reduce wrinkling, and introduce a silky lustre to the fabric appearance. Fiber. Ramie is most often blended with other fibres for its unique strength, absorbency, lustre and dye affinity. The degummed ramie contain a residual gummy content of 1-5% according to the type of spinning process to be used, dry spinning requires a clean fibre, white wet spinning requires a gum reside. Ramie is a bast fiber. The pectin of ramie fibers has a high level of stickiness is and does not easily decompose. Deep eutectic solvents (DESs), featured as promising green solvents, were applied to examine their effectiveness in pretreating raw ramie fibers (RFs) for cellulose nanofibril (CNF) production. Spinning mills were operated in England, France and Germany towards the end of the nineteenth century. The part used for fiber is the vegetative stalk bark, making this a bast fiber. Related Titles. The right time for harvesting is judged by the colour of the stems and the slowing down of their growth. Ramie fibre will be graded before taken in to processing industry. In principle, any machine which is used for sisal or kenaf decortications can be adjusted for ramie. of Agriculture) ; no. Course ramie fibers are used to make twine, rope and nets. This long fibre is spun separately. Ramie may also be spun on the worsted and long draft cotton systems, but in the latter case stapled noils are used and usually blended with cotton or synthetic fibres. Brazil began production in the late 1930s with production peaking in 1971 with about 30,000 t. Because of its high molecular crystallinity, ramie is stiff and brittle and will break if folded repeatedly in the same place; it lacks resiliency and is low in elasticity and elongation potential. It has strong ability to hold shape, reduce wrinkle. Ramie is one of the oldest textile fibers. Properties of Ramie Fibers: The properties of ramie fibers are given below: Ramie is a cellulosic natural fiber. As mentioned above, ramie is not retted in the same way as are other stem fibres such as jute, hemp, flax, etc., because the pectinous substances in ramie are far more difficult to remove or break down than those present in these other fibres. Ramiè (the ramia) is an ancient natural fiber of vegetable origin derived from horticultural plants, the complex processing of the textile fiber makes ramie very rare in fashion, where we can highlight its use mainly in small tailoring companies. The plants should be cut when the flower begins to fall and the seed to form. Japan, Germany, France and the UK are the main importers, the remaining supply is used domestically.[3]. Currently National Institute of Research on Jute and Allied Fibre Technology (NIRJAFT) is working for the development of a new grading system for ramie fibre. Jute is a long, soft, shiny bast fiber that can be spun into coarse, strong threads. (1911). Ramie is a vegetable fiber that has been exploited for human use for thousands of years. PRELIMINARY PROCESSING OF RAMIE: FIBRE EXTRACTION, Pest and Diseases Management in Cashew Nut, Cultivation Practices of Sesame ( Gingelly ). [3], The dry weight of harvested stem from crops ranges from 3.4 to 4.5 t/ha/year. A combined process technology for degumming and bleaching for ramie fibre in a single bath is under progress in NIRJAFT (National Institute of Research on Jute and Allied Fibre Technology), Kolkata. 585. Instead, it must first undergo a severe pounding or scraping to remove the outer bark, which is administered by hand or by one of the many types of decorticating machines. Third, the residual cortex material is washed, dried, and degummed to extract the spinnable fiber. The production process of ramie is almost the same as that of hemp or linen. Title. The weight loss during degumming can be up to 25%, giving a yield of degummed fiber of about 1,200 kg/ha/year. Ramie was used to produce an open-weave fabric called mechera, used for shirts and dressing gowns suitable for warm climates. The stems are green until they are mature, but then they begin to turn brown, starting at the bottom. Ramie is normally harvested two to three times a year, but under good growing conditions can be harvested up to six times per year. The gums of ramie are composed of araban and xylans which are insoluble in water but easily soluble in alkaline solutions. Shorter fibres and waste are used in paper manufacture. The French painter Raoul Dufy designed in the early 20th century patterns for prints on mechera used by the French shirtmaker Charvet. Farmers have been using their fiber to weave clothing. In ramie crop, return comes mainly from the second year onwards. It has smaller leaves which are green on the underside, and it appears to be better suited to tropical conditions. Decorticators developed for ramie include small mobile types suitable for use in the field and larger machines designed for central operation. Chisholm, Hugh, ed. It’s processing is as like linen fiber. Ramie fibre is extracted through decorticator machine. Ramie is also suitable for blending with both natural and synthetic fibres in different proportions.
