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. Ramie is used to make such products as industrial sewing thread, packing materials, fishing nets, and filter cloths. It is one of the strongest natural fibres having rich cellulose content. In the current scenario, there is no specialized spinning system in India is available for ramie and is spun in jute system. Still in present scenario, there is much scope for research and development on this valuable fibre. The decorticator and decorticated ramie fibre is shown as in Fig. The yield of ribbons varies between 2-4% of the weight of the green plant and yield of degummed fibre is normally about one percent of the weight of the green plants. 1b. Aliphatic C-H stretching of cellulose and hemicellulose is indicated by the peak 1377 cm–1 29. The fibre yield and area of cultivation is shown in the Fig. China is the biggest producer of ramie fibre followed by Brazil and Philippines (Fig. Now, the main problem of decorticating machine is, availability and that too at reasonable or affordable price by farmers. Ramie can be used, generally speaking, for those purposes for which flax and hemp are normally used-particularly for twines and threads, for which purposes its properties of strength and lack of stretch make it most suitable. The blended yarns have good scope in the areas like home furnishing, upholstery and industrial fabrics. Ramie is a flowering plant that is native to Asia. 1a). Still, countries like Brazil, India, Philippines, Taiwan, France, etc., are also cultivating ramie in small volumes. After the fibre has been submitted to the degumming action, it is thoroughly washed and dried. 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. However, profitable growing for fibre purpose is based on the principle of as many cutting a year as possible and to produce the best results the plants requires a favourable climate with steady high temperature, a humid atmosphere and a well-distributed annual rainfall of not less than 1.125 mm. In principle, any machine which is used for sisal or kenaf decortications can be adjusted for 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. 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. In India, national level institutes like National Institute of Research on Jute and Allied Fibre Technology (NIRJAFT), Central Research Institute for Jute and Allied Fibres (CRIJAF) are working to innovate ramie fibre in the front line. It is also known as china grass2. It is harvested and processed to yield strong fibers of the same name, which are used in the production of textiles, twine, upholstery, filters, and sacking.Like flax, jute, and hemp, ramie is considered a bast fiber crop, meaning that the usable portion of the plant is found in its connective tissue structures. They are not only using for making clothing, but also finds other diversified applications. Some users (textile mills) have lost interest in the fibre mainly because of the problems of irregularity of quality supply and as well as processing difficulties and these have further discouraged the industrial sector from promoting the use of ramie. Planters harvest ramie approximately every 60days by cutting mature bast and protect roots. (Brittain Bragunier), KW - AgSpace KW - crop yield KW - economic outlook and situation KW - Fiber … Ramie fiber is one of the premium vegetable fibers. 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. Kenaf Ramie Fiber Processing Machinery Hemp Flax Decorticator And Raspador , Find Complete Details about Kenaf Ramie Fiber Processing Machinery Hemp Flax Decorticator And Raspador,Pineapple Fiber Decorticating Machine,Hemp,Kenaf Fiber from Shellers Supplier or Manufacturer-Zhengzhou Alpha Machinery Co., Ltd. Ramie is similar to linen fiber. Ramie is a so-called bast fiber, like flax, jute, and hemp. The SEM images showing the effect of combined degumming and bleaching is shown in Fig. Ramie has been used as a textile fibre in China and Southern Asia for centuries and it is said to have been known in ancient Egypt. Decorticators developed for ramie include small mobile types suitable for use in the field and larger machines designed for central operation. 7. Because of this variable length, before the fibre is subjected to spinning process, it is cut in to uniform size. 8. Decortication is to be done immediately after harvest and therefore, a harvesting schedule is planned in relation to the decortications capacity of the machines used9. Generally two methods of grading are adopted. Long staple fibres can be used for spinning, where as short fibres are using for the manufacture of papers, composites, non woven and other products39,40. Properties of degummed ramie fibres make it more attractive and better than cotton. Among all the bast fibres, major content of cellulose is found in the ramie. The fibres support the conductive cells of the phloem and provide strength to the stem. Degumming is not really a chemical problem but a technological one and good degumming requires good chemicals, good fibre free of extraneous materials and spinning technology and in addition a ‘touch’, which can only be acquired after long experience41. The fibre is derived from the inner bast tissues of the stem. After degumming the cellulose content of the fibres are raised above 95%. Ramie is commonly known as china grass, green ramie or rhea. Earlier so many countries tried to cultivate ramie, some of them withdrawn the cultivation due to some inevitable situations. Ramie is also suitable for blending with both natural and synthetic fibres in different proportions. Dewey." The ribbons of ramie, on their arrival at the factory, are greenish yellow to yellowish-white strips. 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. Prolonged treatment with strong alkali and strong acids causes loss in strength of the fibre and also hydrolysis of cellulose. The ultimate fibers are exceptionally long and are claimed to be the longest of vegetable origin, with one report claiming the fibers range up to 580 mm, averaging about 125 mm. Still considerable research works are going on the application of ramie fibres in new areas like composites are the promises for tomorrow’s technology, which shows a clear indication towards the prosperity of the fibre in the coming future. The study of She et al. Removal of the gum enables the fibre to take a more crystalline form. It is important that ramie should be harvested at the right time if the best fibre is to be obtained. The density of fibre ranges from 1.50-1.55. The peak at 1424 cm–1 corresponds to the bending vibration of CH2 for crystalline as well as amorphous cellulose27. ASCI, Investigating the Physical Properties of Treated and Untreated Jute Fibre-Polyester Composites, Study on Improvement in Handle Properties of Wool/Cotton Union Fabric by Enzyme Treatment and Subsequent Polysiloxane-based Combination Finishing, Eco-friendly Surface Modifications of Wool Fiber for its Improved Functionality: It is having a moisture regain of around 12%. Stalks becoming dry after harvest cannot be properly decorticated. Ramie is an important fiber crop used in textile processing. 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. The ramie plant is a hardy perennial belonging to the Urticaceae or Nettle family, which can be harvested up to 6 times a year. Ramie (Boehmeria nivea) is a perennial crop valued for its strong bast fibers. In another work36, degummed ramie fibre of cut staple length 20 cm was processed in flax carding system and subsequently blended with jute fibre during drawing stage. Bast fibres, like linen and flax are obtained from the phloem, or inner bark (or skin) of a plant. The market prize of ramie fibre is determined by grading system. 2 and 3. Colour, strength, softness, length, fibre separation and defects (major, minor). It is essential to remove the excess of alkali by acetic acid treatment after chemical degumming, otherwise the fibre strength will be reduced. However, other reports claim that the tensile strengths of cotton, flax, hemp and ramie are similar. Before spinning, the fibres are sorted into three lengths, i.e., long, medium and short. Ramie fiber is collected from the bark of the vegetable stalks. The peak at 1328 cm–1 correspond to aromatic skeletal vibrations, ring breathing with C–O stretching in lignin components28 and 1161 cm–1 corresponds to the C-O-C asymmetric stretching in cellulose I and cellulose II. Use of decorticators in the field saves the cost of transporting unwanted plant material to soil10. 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 aim of the study was to remove noncellulosic gummy materials from the fiber thus softening it and prepare nonwovens through needle punch method. Of course, numerous patents have been published relating to the degumming of ramie and there is certainly death of information on the subject. The high potentiality of Ramie is not much exploited in counties, other than china. In spite of the undoubtedly good properties of ramie fibre, the wide occurrence of the plant and the enormous amount of publicity which has been given to the subject from time, the fibre has not so far been developed or used on any large scale outside of China and Japan. The fiber has limited application in textiles due to its high stiffness and less cohesive properties. But it is only in comparatively modern times that the production of ramie fabric has become established on a commercial scale. The extracted fibres contain approximately 25-30% gum12. 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 technical difficulties may be summarized as: Apart from any economic or technical reasons, the development of any new fibre needs market development work of some kind. In Europe, Brazil and the Philippines, some modifications are made. Then, the cortexes are scraped to remove shell and partial gums. Generally it grows up to a height of 1-25 m, the leaves are heart-shaped, 7-15 cm long and 6-12 cm broad and white on the underside with dense small hairs. The use of ramie is limited by its price and spinning properties. 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 greater utilization of ramie depends upon the development of improved processing methods. Finally analyse the effect of lattice distortion modification processing on the lattice structure of ramie fiber. Ramie is widely cultivated not only in China, Japan, India and Malaya, but also in Queensland, Mauritius, the Cameroons, the West Indies, Brazil, Mexico and the southern states of North America, South Europe. 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. Some have been in use for a long while, but they all have drawbacks for commercial big scale production. Harvesting: The stems are green until they are mature, but then they begin to turn brown, starting at the bottom. Unlike other major bast fiber crops, ramie fiber processing does not include retting, but does require degumming, suggesting distinctive features in pectin and the development and composition of fibers. From the Fig. Strong band at 1026 cm–1, assigned to C–O stretching in cellulose, hemicelluloses and lignin or C–O–C stretching in cellulose and hemicelluloses30. Ramie fibre will be graded before taken in to processing industry. 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. After three passages of successive drawing, the sliver was processed through jute roving machine and finally spun in to a yarn of 84 tex. The finest yarns are produced on the spun silk system developed by the Japanese, but this system is labour intensive. These discrepancies can be partly attributed to the effects of source of supply, method of processing, the test conditions, temperature and humidity, on the fiber strength. The total lifespan of the crop ranges from 6-20 years4. In India it is called by different popular names such as Rhea, Popah, KhunKoora, Kurkunda etc. Cellulose is a polysaccharide (i.e., a polymeric sugar) which can be represented by a simple formula (C6H10O5)n. The chemical composition of ramie fibre is as shown in Table 1. The separated cells of ramie, known as "filasse" although white and clean, are still somewhat harsh and dry. The adaptation of the plant to soil is another retarding factor. Ramie fibre is a bast fibre obtained from the inner bark of the ramie stem3. However, the development of a greater ramie industry has been hampered, first, by technical difficulties resulted from the nature of the fibre and secondly, by commercial difficulties attendant upon the introduction of most new textiles. Hand and eye method and instrumental method. 9, it is inferred that, the thermal decomposition of ramie fibre was minimum up to 275°C. Here, I have written about the properties of ramie fibers. Form the table 1 it is observed that the cellulosic content in ramie is much more than other bast fibre like Jute and Hemp. The coarseness of the fibre reduces its scope of application in apparels, but suitable blending may solve this issue. Firstly, process ramie fibers by the lattice distortion modification processing equipment. For proper extraction of fibre, efficient decorticating machines or decorticators are needed to be made available to the growers at reasonable price. China holds the monopoly in both production and exporting of ramie. So, it is always better to remove the gum content of ramie fibre before going for the processing of the fibre. It is highly crystalline fibre. Ramie fiber is very durable, is pure white in colour and has a … It is one of the strongest fiber then others. Another difficulty with the crop is its very low production by itself. It is having good wetting strength but poor in elasticity, abrasion resistance and wrinkle recovery. See more ideas about fiber, plant fibres, natural fibers. This study briefs the extraction, mechanical processing, fibre properties and value addition of ramie fibre. PROCESSING. Coming to the present condition of cultivation in India, very few areas of states like West Bengal and Assam is showing some interest and the production is very minimal. Ramie fibre is easily identified by its coarseness, thick walls, lacks twist and has striated surfaces25. AU - Robinson, Brittain B. Ramie is still not used much by the textile industry largely because it is a high cost fibre due to its complex processing requirements. 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 [2]. The existing jute grading system can also be adoptable in the case of ramie. The retting process of ramie involves lots of chemicals and is labor-intensive. The process of removal of gum from the fibre is known as degumming. In China elsewhere in the far East, ramie is used for a number of purposes such as clothing, table-cloths, handkerchiefs, etc. 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 reside31. In Ramie Research Station, a regional station of Central Research Institute on Jute and Allied Fibres at Sarbhog, Assam, a collection of 55 ramie germplasms are maintained. In a study the degumming of ramie with sodium metasilicate, alone or in combination with other alkali solutions such as sodium carbonate, trisodium phosphate and sodium metasilicate phosphate, has been reported23. An Overview, Microbial Lipases and Their Industrial Applications: Review, Study on the Physical Properties of Blended Rotor Spun Yarn, https://scialert.net/abstract/?doi=ajt.2017.1.9. Also, one should know the advantage and disadvantage of ramie fiber. On the other hand, growers of ramie are not likely to produce large quantities of the fibre-unless they have a reasonable assurance that there would be a large demand for it. The thermogravimetric analysis of ramie fibre is shown in Fig. PRELIMINARY PROCESSING OF RAMIE: FIBRE EXTRACTION. Degumming is still treated as trade secret by the mills that have perfected this art. Unlike other bast crops, ramie requires chemical processing to de-gum the fiber. 6. Due to the presence of gum, the fibre becomes stiff and brittle. 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 Title Ramie Processing treatment commercial processing Image Identification information Ramie-003-06-19-09-POL-400X-PM-9 Image capture digital Date of image capture 06/19/09 Microscopist L. Crawford Microscope Zeiss Axioplan Mounting agent and RI RI: permount 1.515 Microscopic technique Polarized light, fiber at maximum brightness Lumen type On gum removal, the crystallites increase in width but deteriorate with regard to their alignment along the fibre axis21. Ramie, Fiber plants, ramie, plant fibers, natural history, plant cultural practices, harvesting, processing technology, crop yield, plant characteristics, economic outlook and situation Publisher ... Ramie, a fiber-yielding plant, by Lyster H. It is a durable fiber. There may be several reasons behind it, especially, the difficulties associated with decortication, degumming, pest and diseases. The right time for harvesting is judged by the colour of the stems and the slowing down of their growth. In Japan, ramie is used for canvas, suit-cloth, mat-edge, cloth and a large number of other purposes7. The quality of decortication and fibre recovery also depend largely on the efficiency of the operator as well as condition of the plants. This long fibre is spun separately. The stems are green until they are mature, but then they begin to turn brown, starting at the bottom. Ramie fibre comes under bast fibre category, which can be classified as underutilised fibres. The greater utilization of ramie depends upon the development of improved processing methods. The FTIR spectrum of raw ramie fibre is shown in Fig. The tensile strength varies from 400-1600 MPa. The photograph of ramie plant is shown in Fig. During this period, it can be harvested up to 6 times in a year. This produces coarser count yarn but much less labour is required. Abstract. Mistakes in degumming process can ruin the fibre and cause a spinner considerable loss since the know-how for carrying the degumming operations are not freely available. Anhydrous liquid ammonia was used as a solvent for the cationic modification of ramie fiber using 2, 3-epoxypropytrimethylammonium chloride (EPTAC). OPEN ACCESS Asian Journal of Textile ISSN 1819-3358 DOI: 10.3923/ajt.2017.1.9 Review Article Ramie Fibre Processing and Value Addition 1Seiko Jose, 2S. It was used in mummy cloths in Egypt during the period 5000-3300 BC and has been grown in China for many centuries. This machine is using to peeling the kinds of fibre from kind of ramie (ramee), jute, kenaf (ambary), hemp, etc. Lignocellulosic fibres like flax and ramie are also getting popularized in the current era. During eighteenth and nineteenth centuries, ramie cultivation became established in many areas of the western world. Again, from dielectric behaviour … N1 - Caption title. Includes bibliographical references Addeddate Ramie is one of the oldest fiber crops, having been used for at least 6,000 years, and is principally used for fabric production. 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. From the figure it is observed that after the chemical treatment, the fibres are found to be clean. The high potential of ramie fibre is not fully exploited due to various techno-economic reasons. 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%. Let’s have a look on the factors. Then use X-ray diffraction method to determine the crystallinity and orientation of pristine and modified ramie fibers. The fibre possesses some very valuable properties because of its silky, luster, unparallel strength, durability and its suitability to blend with all other natural and manmade fibres. It possesses highest strength and length, good durability and absorbency with excellent lustre. Today some of the fashion designers are showing much interest in ramie fabric due to its unique properties. Among nature fibres, cotton occupied supreme position in both production and consumption. Awareness programs like exhibitions, seminars, training, etc., may encourage the farmers to grow ramie in vast areas. Ramie fibre is one of the premium and oldest textile vegetable fibres. 9. 2. preliminary processing of ramie: fibre extraction The fibre is derived from the inner bast tissues of the stem. As a result of degumming, the gummy matter will be removed and the fibre weight reduces by 22-25%. --- "Revision of, and supersedes Miscellaneous circular no. CHEMICAL COMPOSITION AND FIBRE PROPERTIES. "Contribution from Bureau of Plant Industry." From the physico-mechanical characterization such as: hardness measurement, density measurement, void fraction or porosity measurement, and flexural strength measurement, it is found that the prepared composite is of light weight and high strength. The extracted fibrous material, after washing, should be immediately dried or degummed to prevent the development of mildew. Ramie fiber needs to be processed specifically to get its texture comfortable and useable, because if not, it will have coarse texture. It gives better result when it wet.
