Dongli'S Carbon Fiber Capacity Rises Significantly

A subsidiary of Japan's Dongli based carbon fiber processing company has said its factory expansion in Japan has been completed since October and has doubled its capacity in Japan to produce carbon fiber products.

Statistics show that Dongli is the largest carbon fiber in the world.

In four countries, there are carbon fiber factories.

At present, the total capacity of the global carbon fiber is about 84 thousand tons, and Dongli accounts for nearly 40% of the total.

It is reported that the total investment of Dongli's expansion project in Japan is about 2 billion yen.

The company president of Dongli, Japan, said that carbon fiber is a strategic product and will be used in automobile manufacturing in the near future.

In November of this year,

Announcing the US Boeing company's $8 billion 600 million worth of aircraft.

Orders have become the largest order that Dongli has ever received in the field of aircraft manufacturing.

Carbon fiber is a new type of fiber material with high strength and high modulus, which contains more than 95% carbon.

Its weight is 1/4 of ordinary steel, 30% lighter than aluminum material, but its strength is 10 times that of steel.

At present, a number of famous automobile manufacturers begin to use carbon fiber materials to produce vehicle parts. In addition, the demand for carbon fiber is gradually improving in the field of wind power, aerospace and military industry.

Since mid October, the stock price of Dongli traded on the Tokyo stock exchange of Japan has risen 46%, rising from 670 yen per share to 980 yen.

The cumulative increase has reached 35% this year.

The Haikou experimental station of the Chinese Academy of Tropical Agricultural Sciences has taken the lead in the study of banana in China.

In China, there are about about 10000000 tons of banana waste discarded each year, of which 1% to 2% of the extracted banana stems are available.

Worldwide, bananas yield about 1.065 billion tons a year, and the amount of fiber available is considerable.

According to Sheng Zhanwu's statement, banana fiber is a resource to be exploited and utilized.

Banana fiber can be divided into banana stem fiber and banana leaf fiber.

Banana stem fiber is found in the phloem of banana tree and belongs to bast fiber. Banana leaf fiber is contained in leaves of banana tree and belongs to leaf fiber.

The data show that there are about 130 bananas in the world, with the largest output in Central America, followed by Asia.

Banana cultivation in China is mainly distributed in Guangdong, Guangxi, Fujian, Taiwan, Yunnan and Hainan, and there are also a few cultivation in Guizhou, Sichuan and Chongqing.

Bananas are not only rich in resources, but also relatively concentrated in the region, which is conducive to the implementation of industrialization.

Data show that some foreign enterprises have developed banana viscose fiber.

However, the utilization of banana fiber in China is still at the level of natural fiber.

Sheng Zhanwu said that the banana fibers developed by them were not pulping, the same as ramie, and also natural fibers.

The main chemical components of banana phloem were cellulose, followed by hemicelluloses, lignin, pectin substances, water soluble substances and wax.

The cellulose content in banana phloem is lower than that in flax and jute, but its content is about 60%.

Compared with linen and jute, banana has a higher content of hemicellulose and lignin, and the two accounts for more than 30% of the chemical composition of banana fiber. Therefore, it is relatively difficult to manufacture, and it also causes the luster, softness, elasticity and spinnability of banana fiber, which are all worse than flax and jute.

However, the results showed that the crystallinity and orientation of banana stem fiber were lower than that of flax and jute, indicating that the arrangement of macromolecules in banana fibers was not as regular as that in flax and jute.

Therefore, compared to flax and jute, banana fiber has the characteristics of low strength, large deformation, low birefringence, easy to absorb moisture and moisture, and easy to dye.

In fact, the research on banana fiber in China is not only limited to degumming, but also its high fiber has entered the market.

Mr. Liang, a saint bamboo household textile company, said they had developed a high banana fiber.

However, the cost performance of banana fiber has no advantage.

Mr. Liang said that the market price of banana fiber is 70 thousand yuan / ton to 80 thousand yuan / ton, and its application is basically the same as that of bamboo fiber. Compared with the antibacterial function of bamboo fiber, banana fiber has no outstanding selling points.

And bamboo fiber has been accepted by the market, so they have abandoned the development and production of banana fiber.

The fabric made of banana fiber has also won the national fabric award.

Mr Liang said that they were also very optimistic about the development prospects of this variety, and had sent a large number of samples to customers. However, after considering the customers comprehensively, they did not show positive willingness to purchase.

They also gradually realized that the market's enthusiasm for banana fiber was not as strong as they expected.
