Ramie Biological Degumming Technology Popularization Project Passed Acceptance

Recently, Hunan Yiyang provincial economic and Information Commission organized the experts of the hemp textile industry in Yuanjiang to convene the acceptance meeting of "ramie and other biological fiber degumming clean production technology demonstration project" completed by Hunan star hemp industry. Experts believe that the project is in line with the development direction of ramie industrialization, with remarkable economic, social and environmental benefits, high popularization value and wide market prospect.

The project centers on ramie. Biological degumming The key technologies and industrialization have solved the problems of high energy consumption, heavy pollution, unstable product quality and so on through the high temperature sterilization of ramie raw materials, dry mechanical rubbing, impurity removal, and biological degumming and hemp fiber water bath continuous fermentation technology.

After the implementation of the project, it has significantly improved. Ramie fiber The spinning performance greatly reduced the emission of pollutants and reduced energy consumption. The consumption of 0.83 tons per ton of refined hemp was reduced by 38.85% tons, the comprehensive energy consumption decreased by 38.85%, the water consumption dropped from 750 cubic meters to 350 cubic meters, the inorganic and organic pollutants in the sewage decreased by 90% and 60% respectively, and the COD produced by the refined lees decreased from 370 kg to 160 kg, reducing 57%.

At present, Hunan Star Ma industry and Yuanjiang Xin Xin hemp textile Co., Ltd. and Hanshou Xinda Hemp Industry Co., Ltd. have successfully achieved the promotion of ramie biological degumming industrialization technology and scientific and technological achievements, and the effect is remarkable. At the same time, the Hunan star hemp industry has changed from the original sewage discharge standard to the "three low one high" cleaner production enterprise with low emission, low pollution, low energy consumption and high efficiency, and has been supported by the Ministry of industry and information technology's clean production promotion project special fund of 4 million 500 thousand yuan.

Functional properties of ramie fiber

I. antibacterial and bacteriostatic functions

The same number of bacteria can be observed under microscope. Bacteria can flourish in cotton and wool products, and the bacteria on ramie products are killed about 75% hours after 24 hours. This is because ramie fiber contains exhortation, pyrimidine, purine and other trace elements. It has inhibitory effects on Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and so on. It has natural bacteriostatic, anti mite and deodorant functions. It has been proved by experiments that after 50 repeated washing, the sterilization effect is still over 98%, which can effectively control the two pollution of bacteria and mites in textiles.

Two, deodorization adsorption function

The special ultra-fine microporous structure of ramie fiber has strong adsorption capacity, and it can adsorb harmful substances such as formaldehyde, benzene, toluene, ammonia and so on in the air to eliminate the bad smell. After sunlight, the adsorbed harmful substances can be volatilized, so that the adsorption function can be automatically regenerated.

Three. Moisture absorption and breathability.

Ramie fiber has the reputation of "natural fiber king", its unique active cavity sweat fiber structure can make the inhaled sweat penetrate into the cavity and quickly export, giving it the superior air permeability and heat transfer, water absorption and wet, fast, and has a very pleasant cool feeling.

Four, mildew proof and wear-resisting function.

Ramie fiber is very tough, strong and small extension, and is not susceptible to mold corrosion and moth eaten, known as "Millennium soft gold", it is widely used in parachute, insurance rope, home textiles and other fields, has a strong anti mildew and wear-resisting function, and well extends the service life of the articles.
