The weight loss is mainly because of evaporation of water and volatile substances (low molecular weight waxes and fats). 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. 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. Leading producers of ramie are China, Taiwan, Korea, the Philippines and Brazil. Lignocellulosic fibres like flax and ramie are also getting popularized in the current era. During grading, the following parameters are to be checked. Examples of leaf fiber include sisal, henequen, and pineapple leaf fiber (PALF). 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%. 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. They are not only using for making clothing, but also finds other diversified applications. 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%. The high potentiality of Ramie is not much exploited in counties, other than china. Acid hydrolysis of native ramie cellulose fibre leads to aqueous suspensions of elongated nano crystals with high aspect ratio. This produces coarser count yarn but much less labour is required. The quality of decortication and fibre recovery also depend largely on the efficiency of the operator as well as condition of the plants. 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. The highest yield is attained in the third and fourth years and maintained until the plant is about six years old. Ramie is most often blended with other fibres for its unique strength, absorbency, lustre and dye affinity. Generally caustic soda is used for degumming process. 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. processing of ramie fiber is, therefore, necessary and beneficial to domestic textile manufacturers in understanding ramie properties and gaining hands-on experience of ramie production. But it is only in comparatively modern times that the production of ramie fabric has become established on a commercial scale. 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. 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. By decortication, the outer bark, the central woody core and some portion of the gums and waxes of the bast are mechanically removed. Ramie fibre comes under bast fibre category, which can be classified as underutilised fibres. In Europe, Brazil and the Philippines, some modifications are made. The tenacity, wet strength, extensibility are increases. It acts as an inhibitor for water and other chemicals to enter inside the fibre. During eighteenth and nineteenth centuries, ramie cultivation became established in many areas of the western world. Even though the server responded OK, it is possible the submission was not processed.

As the plant matures, the number of stalks increases with a corresponding increase in yields up to the fourth year, an average of 4, 7, 10 and 13 t of green stalks may be harvested per acre in each of the first 4 years, respectively and 13-17 t annually thereafter. 7. Ramie (Boehmeria nivea L.) is one of the oldest crops in China and the second most important fiber crop in terms of area sown. ABSTRACT Ramie is commonly known as china grass, green ramie or rhea.

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. Natural fibres are gaining importance day by day in all over the world. 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. Ramie is harvested soon after or just before the start of flowering. There may be several reasons behind it, especially, the difficulties associated with decortication, degumming, pest and diseases. Degumming is essential after fibre extraction. This machine is using to peeling the kinds of fibre from kind of ramie (ramee), jute, kenaf (ambary), hemp, etc. It possesses highest strength and length, good durability and absorbency with excellent lustre. Until recently ramie has been unknown in the ready-to-wear market in this country, but it is appearing in more garments. After three passages of successive drawing, the sliver was processed through jute roving machine and finally spun in to a yarn of 84 tex. Dewey." PROBLEMS ASSOCIATED WITH THE CURRENT SCENARIO. The process of removal of gum from the fibre is known as degumming. Ramie, unlike other bast crops, requires the fiber to be de-gummed using chemical processing. These characteristics make it suitable for use in the manufacture of wide variety of textiles and value added products5,6. Degumming is still treated as trade secret by the mills that have perfected this art. Hand and eye method and instrumental method. 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. All that remains is to try it to find out if it is suitable for sweating problems, but we believe that it is not among those fabrics that work miracles.
