Wet spinning of high-performance carbon fiber

On the morning of September 23, 2013, China textile industry association was held in lianyungang city organization dry jet wet spinning of high performance carbon fiber engineering key technology and equipment research and development project technology achievement assessments. Expert group listened to undertake unit reporting, reviewed the identification of materials, an agreement through discussion through the identification of the technology.

It is understood that in 2008, launched dry jet wet spinning double seals SYT45 grade carbon fiber research and development work. Dry jet wet spinning technique is ideal for polyacrylonitrile based carbon fiber precursor developed a kind of high efficient spinning technology, has a high production efficiency, quality of the carbon fiber, low production cost, the incomparable virtues than the wet spinning. At present, 80% of the world's carbon fiber is dry jet wet spinning, dry jet wet spinning process will be the mainstream of carbon fiber in the future. But dry jet wet spinning technology is the carbon fiber industry recognized spinning technology hard to master. Double seals spent two whole years, polymer system eventually created a set of their own scientific and technological achievements.

Jiangsu lianyungang eagle tour group chairman Zhang Guoliang said: the carbon fiber in China is a kind of new process methods, it is the first and the only one in our country. This process make carbon fiber is a leading in the domestic market, many high-tech products in domestic aviation, aerospace, nuclear industry, these can be widely used.
