Ramie

La ramie ou le mosi blanche, est une fibre ressemblant au lin qui vient de la tige de la plante de ramie. Les textiles de ramie blancs tissés à la main de la région de Hansan en Corée ont longtemps été reconnus pour leur texture fine, porosité, couleur de neige et légèreté comme de toile d’araignée, qui en ont fait le matériel préféré pour les vêtements d'été. Beaucoup de choses ici seront nouvelles pour les visiteurs, y compris les expositions de mode et une expérience de tissage.

RAMIE is also similar to linen and is a bast of plant fiber. It is natural white in color, has a high luster and an unusual resistance to bacteria and molds. Used in fabrics, and often mistaken for linen, it is extremely absorbent and dries quickly. Ramie has excellent abrasion resistance and has been tested to be three to five times stronger than cotton and twice as strong as flax. It is an inexpensive fiber from an East Asian plant and can be spun or woven into a fabric

White ramie

The ramie plant, grown mainly as a fibre crop, is also a source of nutritious green feed. The leaves and tops, unlike the stems, have a low fibre content and are rich in protein, minerals, lysine and carotene. The nutritive value of ramie has been described as similar to that of lucerne, which it can, however, greatly outyield. When ramie is grown for fodder, up to fourteen cuttings a year can be taken from established crops, yielding as much as 300 tons of fresh material (42 tons dry matter) per hectare per year. The foliage is palatable and has proved to be of value not only to stock but also to pigs and poultry. Ramie can be grazed, used as soilage, ensiled together with molasses, or artificially dried for leaf meal. Ramie is palatable to all classes of domestic livestock and is an excellent feed for cattle. As long as satisfactory ad lib mineral levels are achieved, ramie can be fed ad lib to pigs of all ages and acceptable production obtained. Ramie meal has proved valuable to poultry as a source of carotenoids and riboflavin. The only problem associated with feeding ramie is its high mineral uptake, especially molybdenum on soils rich in this element; this can be corrected by adding appropriate levels of copper sulphate to the diet.
