Heilongjiang Linen And Cannabis Planting Area Exceeded 200 Thousand Mu

Recently, from the linen Association of Heilongjiang Province, it was noted that in 2014, the area of seed and linen in Heilongjiang exceeded 200 thousand mu, of which 72 thousand Mu was flax and 131 thousand acres of hemp.

The province was once the largest agricultural production base of Flax in China, and declined to the bottom of the valley in the early part of this century.

In 2010, the flax planting area shrank to 5 thousand mu; in 2011, it was affected by

The impact of rejuvenation on linen industry in Heilongjiang began to pick up. Under the impetus of leading enterprises, linen planting increased to 151 thousand mu in 2012; 171 thousand mu in 2013; in 2013, due to rain disaster, flax cultivation was reduced to 107 thousand mu; in 2014, the area of seed and linen in the province exceeded 200 thousand mu, reaching the highest point since twenty-first Century.

According to province

President Wang Yufeng said that since 12th Five-Year, the planting area of bast fiber in Heilongjiang province has been steadily improving. The bottleneck of the most difficult and crucial planting link in the flax industry chain is gradually breaking through, which solves the dilemma that the processing industry of flax industry depends entirely on the import of Western Europe, and is hopeful to be self-sufficient.

Yesterday, the eighty-ninth World Textile Conference opened in Han Dynasty, and nanofibers became a hot topic for experts.

Wang Xun, chairman of the World Textile Conference and Dean of textile School of Wuhan Textile University, is one of the authoritative experts in this field.

He revealed that the yarn made by his laboratory can now be thinner than 100 nm, and the fineness is only half that of the existing nanofibers in the world.

It is understood that the diameter of nanomaterials is smaller than that of bacteria and viruses. If we can achieve mass production, we will be able to withstand the overwhelming majority of bacteria and virus protection products, and deal with PM2.5.

Wang Xun introduced that nanofibers can be used as high-performance materials, including filter materials such as respirators, similar materials such as battery separator, and medical materials.

Compared with ordinary textile materials, high performance materials consume less raw materials and achieve better results.

For example, masks made of nanofibers, because the yarns have been thinner to the nanometer level, and bacteria and viruses are mainly microns, so they can withstand most of the bacteria and viruses, which are much better than the existing masks.

"Like PM2.5, fine masks made of nanofibers can resist 100%.

Of course, if we are to resist Ebola virus, we need more layers of protection, and we need to solve problems such as respiratory obstruction. "

According to Wang Xun, although nanofibers have mature samples in the laboratory in recent years, they have not been able to mass produce, which is exactly what the global textile industry is trying to solve.

There are two main reasons: first, mass production is technically difficult, and the two is high production cost.

At present, Wuhan Textile University is working with relevant enterprises in Jiangsu, and has already been in the forefront of domestic industrialization in the field of nanofiber technology.

It is estimated that the mass production of nanofiber materials will be achieved in the next 3 years and will go to the market.
