It is also made into fabrics for household furnishings and clothing, frequently in blends with other textile fibres. During grading, the following parameters are to be checked. It was used in mummy cloths in Egypt during the period 5000-3000 BC and has been grown in China for many centuries. Fiber. Ramie fiber production . Ramie is also suitable for blending with both natural and synthetic fibres in different proportions. Ramie is most often blended with other fibres for its unique strength, absorbency, lustre and dye affinity. 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. 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). Like linen, it’s a bast fiber – part of the stalk is separated from the plant and woven into yarn.It’s also similar to linen in that the fiber is relatively brittle and creases easily and ramie … Ramie fiber is collected from the bark of the vegetable stalks. 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. Ramie is also occasionally used in the construction of high performance rowing oar shafts. However, the process of separating the fiber from the plant stem’s bark and woody portions requires significant hand labor or mechanized processing. It's one of the oldest vegetable fibers, having been used for thousands of years for all sorts of fabrics — including ancient Egyptian mummy wraps!. The best cleaned ribbons on arrival in the mill contain at least 10-15% of gummy matter, whereas the poorer qualities contain 20-30% and this must be extracted. Delayed ramie harvesting will severely affect fiber quality and ramie production in the next season (Peng, 2009). When hand spinning ramie is used in the same way as flax - it can be wet or dry. Ramie fibre is extracted through decorticator machine. The tenacity, wet strength, extensibility are increases. Long staple fibres can be used for spinning, where as short fibres are using for the manufacture of papers, composites, non woven and other products. 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. It’s processing is as like linen fiber. Other producing countries include Brazil, Philippines, Lao People’s Democratic Republic and Japan. Ramie is also readily dyed but hard to spin. Some or all are needed to separate the raw fiber from the adhesive gums or resins. 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%. (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 Spinning mills were operated in England, France and Germany towards the end of the nineteenth century. Ramie is one of the oldest fiber crops, having been used for at least 6,000 years, and is principally used for fabric production. 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. Encyclopædia Britannica (11th ed.). Its luster is fine and silky and it creates good appearance in fabric. Removal of the gum enables the fibre to take a more crystalline form. World production of ramie fiber (ton) 2. The pectin of ramie fibers has a high level of stickiness is and does not easily decompose. It may have been used in cloth for wrapping mummies in Egypt. Ramie Clothing Care labels may vary according to fiber blends, so read and follow these. Properties of Ramie Fibers: The properties of ramie fibers are given below: Ramie is a cellulosic natural fiber. Chisholm, Hugh, ed. It is the strongest fiber crown known. Title. NP-PL degummed ramie fiber better than PL at 24 and 48 h treatment. Ramie is a vegetable fiber that has been exploited for human use for thousands of years. The fibre is derived from the inner bast tissues of the stem. Third, the residual cortex material is washed, dried, and degummed to extract the spinnable fiber. Harvesting is done either by manually or by using mechanical harvesters. By Its single fiber is long, the strength is the largest, moisture absorption and moisture dispersing are quick, heat conduction performance is good, white after gluing has mermerization, can be pure spinning, and can also be mixed with cotton, silk, wool, chemical fiber, etc.. Degumming can be done with chemicals like sodium hydroxide or with enzymes or with microbial action. 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. In Europe, Brazil and the Philippines, some modifications are made. A 4.5-ton crop yields 1,600 kg/ha/year of dry undegummed fiber. Ramie fiber production by Robinson, Brittain B.
