The Hunan provincial Fiber Inspection Bureau / national ramie product quality supervision and inspection center presided over the Hunan Ramie Technology Research Center. Hunan Star Ma Co., Ltd. and other units involved in the drafting. This standard determined for the first time the 5 quality indexes of ramie fiber, such as linear density, average length, short fiber ratio of 15mm and below, long fiber ratio of 40mm and above, and hard strip rate, and clearly determined the evaluation standard of RAMIE NOIL, grade two, three and so on.

Ramie refined hemp is hosted by China Fiber Inspection Bureau, Hunan Fiber Inspection Bureau, Hunan Huasheng Group, Hunan star ma Limited by Share Ltd, Hubei essence. Spin Limited companies and other units participated in the amendment. This standard mainly refers to a large number of notarization tests of ramie and refined hemp in Hunan Province in 2008/2009 and 2009/2010. data On the basis of this, some technical indicators of the national standard of ramie refined hemp (GB/T20793-2006) have been revised.

Ramie is a nettle plant, one of the most important fiber crops in ancient China. The fabric made of ramie is longer than that of cotton, and its length is several times longer than that of cotton. The ramie fiber treated by degumming has good gloss and whiteness. The characteristics of ramie fabric are breathable and cool. This is mainly due to the large gap in its structure, so it is very breathable, and has high water absorption and dispersing efficiency. Compared to cotton, the strength of ramie fiber is more than 7 times of that of cotton, and its elongation is small, and it is not afraid of moth eaten and is not afraid of mold.
