Banana Fiber to fabric | Extraction Process, Yarn Spinning & Weaving Process | Innovative Textile: What is Banana Fiber? There are 2 major varieties of ramie plants. 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 plants should be cut when the flower begins to fall and the seed to form. 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. Acid hydrolysis of native ramie cellulose fibre leads to aqueous suspensions of elongated nano crystals with high aspect ratio. The separated cells of ramie, known as "filasse" although white and clean, are still somewhat harsh and dry. The blended yarns have good scope in the areas like home furnishing, upholstery and industrial fabrics. The market prize of ramie fibre is determined by grading system. 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. Among nature fibres, cotton occupied supreme position in both production and consumption. Degumming is still treated as trade secret by the mills that have perfected this art. Generally caustic soda is used for degumming process. Ramie fibre is one of the premium and oldest textile vegetable fibres. The white snow boomer is not used in the textile industry on a large scale because the high cost of raw materials remains, since its production requires complex processes. 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. 4 and 5. 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. 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. Its absorbency properties are extremely high. 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%. 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 degum- ming process in ramie might be compared to the retting of flax, hemp, and jute. 8. Ramie is a fiber obtained from cellulose and as such its breathability characteristics vary greatly depending on the type of fabric processing. 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. 9, it is inferred that, the thermal decomposition of ramie fibre was minimum up to 275°C. Today some of the fashion designers are showing much interest in ramie fabric due to its unique properties. Required fields are marked *. If the stems are allowed to become too mature, lignification takes place. Even though the server responded OK, it is possible the submission was not processed. N1 - Caption title. In China elsewhere in the far East, ramie is used for a number of purposes such as clothing, table-cloths, handkerchiefs, etc. Stems are harvested by bending the stem or cutting just above the lateral roots. The traditional chemical degumming method is a complex process, which is neither an eco-nomic nor an ecofriendly way, and an economic and environment- -friendly degumming method with simple process and low cost is very much needed[5]. The fibre yield and area of cultivation is shown in the Fig. Please contact the developer of this form processor to improve this message. 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. 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. Until recently ramie has been unknown in the ready-to-wear market in this country, but it is appearing in more garments. The right time for harvesting is judged by the colour of the stems and the slowing down of their growth. The right time for harvesting is judged by the colour of the stems and the slowing down of their growth. This long fibre is spun separately. 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 a bast fiber, and the fiber used for textiles comes from the inner bark of the vegetative stalks and not the woody stem or outer bark.Ramie is normally harvested two to three times a year, but under good growing conditions can be harvested up to six times per year. During grading, the following parameters are to be checked. 2. It acts as an inhibitor for water and other chemicals to enter inside the fibre. fore ramie fiber could be used in textile, it requires chemical processing to degum the fiber. Ramie leaves are highly nutritious and can be used food as well as … But it is only in comparatively modern times that the production of ramie fabric has become established on a commercial scale. MANUFACTURING AND USES The first step in the processing of ramie is degumming, which has not in the past been considered as part of the agricultural prepara- tion of the fiber, but the first step in manufacturing. 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.

The quality of decortication and fibre recovery also depend largely on the efficiency of the operator as well as condition of the plants. 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. Unlike other bast crops, ramie requires chemical processing to de-gum the fiber. The stems of ramie grow to a height of 1 to 2.5 m. The crop is generally propagated vegetatively, using rhizome or stem cuttings. It is almost 6 times stronger than cotton, 2 times that of flax and almost equals silk in its lustre. The individual growers may not be in a position to make such investment for raising the crop. 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 ramie plant is a … The extracted fibrous material, after washing, should be immediately dried or degummed to prevent the development of mildew. The finest yarns are produced on the spun silk system developed by the Japanese, but this system is labour intensive. This machine is using to peeling the kinds of fibre from kind of ramie (ramee), jute, kenaf (ambary), hemp, etc. 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. 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. Lignin degradation starts at about 280°C and continues even above 500°C. It is highly crystalline fibre. Use of decorticators in the field saves the cost of transporting unwanted plant material to soil10. Among all the bast fibres, major content of cellulose is found in the ramie. Let’s have a look on the factors. The highest yield is attained in the third and fourth years and maintained until the plant is about six years old. 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. A whole sequencing run was performed on the 454 GS FLX + platform using four separately pooled parts of ramie bast 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. Ramie was one of the principal plant fibres used in the orient for making cloth before the introduction of cotton, which took place in China about 1300 AD 1. Use of decorticators in the field saves the cost of transporting unwanted plant material to soil. Materials. 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 fibre comes under bast fibre category, which can be classified as underutilised fibres. 2. Abstract : Ramie is commonly known as china grass, green ramie or rhea. The stems are green until they are mature, but then they begin to turn brown, starting at the bottom. In principle, any machine which is used for sisal or kenaf decortications can be adjusted for ramie. Lignocellulosic fibres like flax and ramie are also getting popularized in the current era. It is resistant to bacteria, mildew, mild alkalis, rotting26, sunlight and insect attack. With favorable mechanical properties, ramie fiber composites are attractive structural materials for doors, panels, and furniture. Harvesting and Threshing. 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. 9. It possesses highest strength and length, good durability and absorbency with excellent lustre. 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.
