The fiber has limited application in textiles due to its high stiffness and less cohesive properties. Ramie is similar to linen fiber. Then, the cortexes are scraped to remove shell and partial gums. It is a durable fiber. Stalks becoming dry after harvest cannot be properly decorticated. Ramie is most often blended with other fibres for its unique strength, absorbency, lustre and dye affinity. Another difficulty with the crop is its very low production by itself. Firstly, process ramie fibers by the lattice distortion modification processing equipment. 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. Then use X-ray diffraction method to determine the crystallinity and orientation of pristine and modified ramie fibers. The adaptation of the plant to soil is another retarding factor. Removal of the gum enables the fibre to take a more crystalline form. The blended yarns have good scope in the areas like home furnishing, upholstery and industrial fabrics. 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. 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 retting process of ramie involves lots of chemicals and is labor-intensive. Mar 13, 2018 - Explore Bansky Bernadett's board "Ramie- Fiber" on Pinterest. It was used in mummy cloths in Egypt during the period 5000-3300 BC and has been grown in China for many centuries. There are 2 major varieties of ramie plants. They are not only using for making clothing, but also finds other diversified applications. Ramie fiber is collected from the bark of the vegetable stalks. 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. The fibre is coarser and consists of hairs, projecting from the surface, its length varies considerably from 40-200 mm and the fibre diameter is around 25-30 μm. Ramie is a premium plant fibre with several useful characteristics and improvements in processing methods may well result in ramie becoming a … 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 greater utilization of ramie depends upon the development of improved processing methods. The market prize of ramie fibre is determined by grading system. The fibre yield and area of cultivation is shown in the Fig. The extracted fibres contain approximately 25-30% gum12. The problems associated with cultivation, decortication and degumming are the researchable issues. Dewey." In the current scenario, the textile industries are not showing much interest in the processing of ramie due to the difficulties associated with degumming and unsteady supply of fibre in the market. Ramie fiber. After three passages of successive drawing, the sliver was processed through jute roving machine and finally spun in to a yarn of 84 tex. Ramie is a flowering plant that is native to Asia. In India it is called by different popular names such as Rhea, Popah, KhunKoora, Kurkunda etc. It is also made into fabrics for household furnishings and clothing, frequently in … Ramie is an important fiber crop used in textile processing. CHEMICAL COMPOSITION AND FIBRE PROPERTIES. Ramie fibre is a bast fibre obtained from the inner bark of the ramie stem3. First harvesting can be done after 17 days of planting and followed by 45-60 days for the succeeding harvests. In China elsewhere in the far East, ramie is used for a number of purposes such as clothing, table-cloths, handkerchiefs, etc. 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. Some have been in use for a long while, but they all have drawbacks for commercial big scale production. Weight loss (%) ramie fibre subjected to heating in varied temperature, indicating nature of thermal decomposition, https://scialert.net/abstract/?doi=ajt.2017.1.9, FAO statistics, 2013, (a) Fiber yield hg ha, Varieties of ramie, white ramie and green ramie, SEM photograph of (a) Decorticated (b) Combined degummed and bleached ramie fibre, Chemical composition of bast fibres by percentage mass, Mechanical methods of extracting the fibre from the stalks and, particularly, for subsequent degumming of the strands are still in an experimental stage, Although flax, cotton and silk machinery have been utilized for processing, ramie is best prepared on machinery constructed primarily for the purpose, Surface of the fibres is very smooth and difficulty is encountered in making the strands interlock when spinning fine counts of yarns, so that ramie fabrics have a tendency to be uneven. The finest yarns are produced on the spun silk system developed by the Japanese, but this system is labour intensive. Prolonged treatment with strong alkali and strong acids causes loss in strength of the fibre and also hydrolysis of cellulose. This machine is using to peeling the kinds of fibre from kind of ramie (ramee), jute, kenaf (ambary), hemp, etc. The process of removal of gum from the fibre is known as degumming. Ramie fiber needs to be processed specifically to get its texture comfortable and useable, because if not, it will have coarse texture. Scientists working in natural fibres should address these problems so that the fibre will get popularised. But it is only in comparatively modern times that the production of ramie fabric has become established on a commercial scale. --- "Revision of, and supersedes Miscellaneous circular no. Cortexes removed mechanically or manually in a process, so-called decorti-cations. 1a). 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. 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. It is referred to as bast fiber. China holds the monopoly in both production and exporting of ramie. Use of decorticators in the field saves the cost of transporting unwanted plant material to soil10. Again, from dielectric behaviour … 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 processing22. Harvesting and Threshing. 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. Ramie fibre comes under bast fibre category, which can be classified as underutilised fibres. 2. --- "Contribution from Bureau of Plant Industry." Ramie fiber is one of the premium vegetable fibers. 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. The results show that, compared to long ramie fibers processed in a conventional ramie spinning system, the stretch-broken fibers, with reasonable fiber length and high length uniformity, can be processed in a cotton spinning system with high efficiency … 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 decortications11. Still in present scenario, there is much scope for research and development on this valuable fibre. 6. This study briefs the extraction, mechanical processing, fibre properties and value addition of ramie fibre. Anhydrous liquid ammonia was used as a solvent for the cationic modification of ramie fiber using 2, 3-epoxypropytrimethylammonium chloride (EPTAC). The study of She et al.

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. Generally caustic soda is used for degumming process.
