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 is a fiber made from a plant of the same name – a member of the nettle family. 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. Shorter fibres and waste are used in paper manufacture. 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. First harvesting can be done after 17 days of planting and followed by 45-60 days for the succeeding harvests. 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. Ramie fiber is known especially for its ability to hold shape, reduce wrinkling, and introduce a silky lustre to the fabric appearance. [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. First, the cortex (bark) is removed; this can be done manually or by machine. 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. What is Ramie? 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%. Ramie is one of the oldest fiber crops, having been used for at least 6,000 years, and is principally used for fabric production. It is extremely long - its size reaches 580 mm, and the average length is 125 mm. • NP-PL enhanced the fiber tenacity and fineness. It is essential to remove the excess of alkali by acetic acid treatment after chemical degumming, otherwise the fibre strength will be reduced. This enables the core to be broken and the cortex can be stripped from the plant in situ. The decorticator and decorticated ramie fibre . A second type, known as green ramie or rhea, is believed to have originated in the Malay Peninsula[citation needed]. Greater utilization of ramie may depend upon development of improved processing methods and the need to find plastic alternatives.[9]. 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. The process of removal of gum from the fibre is known as degumming. Farmers have been using their fiber to weave clothing. During grading, the following parameters are to be checked. In the current scenario, there is no specialized spinning system in India is available for ramie and is spun in jute system. Various aspects such as Ramie Fiber import or export, price, gross margin, consumption, and cost are also analyzed. Brazil began production in the late 1930s with production peaking in 1971 with about 30,000 t. 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. Ramie fiber production by Robinson, Brittain B. Blogger of Innovative Agriculture. Interested in Innovative ideas, Ramie is one of the oldest fiber crops, having been used for at least 6,000 years, and is principally used for fabric production. Cambridge University Press. Ramie is normally harvested two to three times a year, but under good growing conditions can be harvested up to six times per year. In principle, any machine which is used for sisal or kenaf decortications can be adjusted for ramie. • NP-PL enhanced RS production from fruit and vegetables peels at 50 and 90 °C. In ramie crop, return comes mainly from the second year onwards. Ramie is most often blended with other fibres for its unique strength, absorbency, lustre and dye affinity. The ribbons of ramie, on their arrival at the factory, are greenish yellow to yellowish-white strips. Related Titles. Ramie is one of the oldest fiber crops, having been used for at least 6,000 years, and is principally used for fabric production. Kadolph SJ, Langford AL. Course ramie fibers are used to make twine, rope and nets. The pretreatment performance of three DESs, i.e., choline chloride-urea (CU), choline chloride-oxalic acid … Asian J. 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. It gives better result when it wet. Ramie is also readily dyed but hard to spin. The stems are green until they are mature, but then they begin to turn brown, starting at the bottom. Only a small percentage of the ramie produced is available on the international market. Encyclopædia Britannica (11th ed.). Mahe Drysdale used sculling oars made with ramie during the 2018 Rio Olympics where he won Gold in the Men's 1X Scull. From the figure it is observed that after the chemical treatment, the fibres are found to be clean. 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. The fact that the fabric ramie, said and used in its production of fiber - one of the best materials of plant origin. If the stems are allowed to become too mature, lignification takes place. 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. Ramie (pronounced: /ˈreɪmi/, RAY-mee; from Malay rami) is a flowering plant in the nettle family Urticaceae, native to eastern Asia. It may have been used in cloth for wrapping mummies in Egypt. It is not as durable as other fibers, so is usually used as a blend with other fibers such as cotton or wool. So, it is always better to remove the gum content of ramie fibre before going for the processing of the fibre. Ramie is used to make such products as industrial sewing thread, packing materials, fishing nets, and filter cloths. It acts as an inhibitor for water and other chemicals to enter inside the fibre. Chemical processing is required for processing ramie. Mainly, it is used for the production of fiber. Japan, Germany, France and the UK are the main importers, the remaining supply is used domestically.[3]. Ramie fiber is collected from the bark of the vegetable stalks. Because of this variable length, before the fibre is subjected to spinning process, it is cut in to uniform size. The pectin of ramie fibers has a high level of stickiness is and does not easily decompose. In Europe, Brazil and the Philippines, some modifications are made. 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 … Harvesting is done either by manually or by using mechanical harvesters. 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). Thus, it is a huge challenge for textile factories to heavily invest in mass production of high-quality ramie due to the massive labor input needed. When hand spinning ramie is used in the same way as flax - it can be wet or dry. You have entered an incorrect email address! It was used in mummy cloths in Egypt during the period 5000 - 3000 BC, and has been grown in China for many centuries. 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. It is similar to linen in absorbency, density, and microscopic appearance. Ramie was used to produce an open-weave fabric called mechera, used for shirts and dressing gowns suitable for warm climates. (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 NP-PL degummed ramie fiber better than PL at 24 and 48 h treatment. One of the two principal crops used is ramie. 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. China leads in the production of ramie and exports mainly to Japan and Europe. Before spinning, the fibres are sorted into three lengths, i.e., long, medium and short. 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. Ramie is normally harvested two to three times a year, but under good growing conditions can be harvested up to six times per year. After the fibre has been submitted to the degumming action, it is thoroughly washed and dried. Ramie is also used as an ornamental plant in eastern Asia. 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. Normally, about 60% of the total weight of the degummed material will be long fibre. The extracted fibrous material, after washing, should be immediately dried or degummed to prevent the development of mildew. Decorticators developed for ramie include small mobile types suitable for use in the field and larger machines designed for central operation. Save my name, email, and website in this browser for the next time I comment. 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. [3], After harvesting, stems are decorticated while the plants are fresh. By The plants should be cut when the flower begins to fall and the seed to form. Aside from its strength, ramie fiber does not stretch or shrink. The gums of ramie are composed of araban and xylans which are insoluble in water but easily soluble in alkaline solutions. China is considered the main producer of ramie fiber. 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. [1], Ramie is one of the strongest natural fibers. [10] Only a small percentage of the ramie produced is available on the international market. The finest yarns are produced on the spun silk system developed by the Japanese, but this system is labour intensive. This fiber was growing in china in the past. Jute is a long, soft, shiny bast fiber that can be spun into coarse, strong threads. On gum removal, the crystallites increase in width but deteriorate with regard to their alignment along the fibre axis. Nowadays, Ramie is used as a cotton substitute. It is the strongest fiber crown known. Ramie fibers are exceptionally long, lustrous, durable, soft, and stronger than cotton. But it is only in comparatively modern times that the production of ramie fabric has become established on a commercial scale. 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 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. [6], Despite its strength, ramie has had limited acceptance for textile use. To make them suitable for spinning, the decorticated ramie fibre has to be degummed in an effort to separate the individual fibres free from gums, waxes and pectins and leave them in a soft, clean state with their strength and other textile characteristics intact. Have lovingly 75%blended Wool, 10%Ramie fiber 15%Nep Fibre or 50% Wool 20% Alpaca 30% Bamboo together to produce a timeless tweed yarn that is perfect for simple stitches, as well as sophisticated lace or cable patterns. Ramie is a vegetable fiber that has been exploited for human use for thousands of years. Production of Ramie Fibre- Ramie (Boehmeria nivea), commonly known as China grass, white ramie, green ramie and rhea, is one of the group referred to as the bast fiber crops. The fibre is derived from the inner bast tissues of the stem. However, the process of separating the fiber from the plant stem’s bark and woody portions requires significant hand labor or mechanized processing. Jute" is the name of the plant or fiber used to make burlap, hessian or gunny cloth. 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). Use of decorticators in the field saves the cost of transporting unwanted plant material to soil. 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. Since then, production has steadily declined as a result of competition from alternative crops, such as soybeans and synthetic fibers. CUltivation practices of ramie The decorticated fibres are cooked in vessels with 1-2% of caustic soda under pressure for 1 h. A slight mistake in the degumming process can spoil the quality of fibre, since the major component in ramie is cellulose and is sensitive to alkali. The right time for harvesting is judged by the colour of the stems and the slowing down of their growth. Due to the presence of gum, the fibre becomes stiff and brittle.
