Aoshen New Materials Co., Ltd., located in Lianyungang City, Jiangsu Province, has successfully trial-produced polyimide fiber (PI fiber). This new fiber can capture PM2.5 particles efficiently at high temperature and protect the air from pollution. This product will provide key core materials for the environmental protection industry after the full implementation of the latest National Ambient Air Quality Standard.
Jiangsu aoshen group seized the strategic opportunity, invested and established Jiangsu aoshen new materials co., ltd in 211, and jointly developed polyimide fiber with Donghua university. The total investment of this trial-produced polyimide fiber project is 5 million yuan, and dry spinning and integrated production technology with independent intellectual property rights are adopted, with high production efficiency, good product uniformity and high solvent recovery rate. In addition, the project team also successfully developed a complete set of polyimide fiber production equipment.
It is reported that during the implementation of this project, two authorized patents have been obtained, namely, a spinneret for dry spinning polyimide profiled fibers and a cyclization device for polyimide fibers, and an exclusive patent for the preparation method of carbon nanotubes/polyimide composite fibers.
in February this year, the newly published "ambient air quality standard" specially increased the monitoring index of PM2.5, and the standard will be fully implemented in 216. Polyimide fiber is a strategic new material and a high-tech fiber product urgently needed by the people during the Twelfth Five-Year Plan period. (China Chemical News)
