Para-aramid fiber pilot research project passed appraisal
“It’s not simple, it’s really not simple. This is the first time I’ve seen the whole process of para-aramid fiber manufacturing live in China.” Ji Guobiao, an academician of the Chinese Academy of Engineering, said excitedly, “I saw para-aramid fiber with Chinese intellectual property rights. A bright prospect for industrialization.”
“It has been more than 20 years since the national ‘Sixth Five-Year Plan’, and after the efforts of several generations of textile technicians, the complete local production of para-aramid fiber has finally been achieved. ” Sun Jinliang, academician of the Chinese Academy of Engineering, said with emotion, “As a technician who has worked in the field of high-performance chemical fibers all his life, I am proud of such high-level technical achievements.”
“This is a landmark scientific research achievement. ,” Yao Mu, academician of the Chinese Academy of Engineering, commented, “It marks that the monopoly of this high-performance fiber by a very few countries has been broken.”
On October 15, the China Textile Industry Conference was held in Shanghai At the technical appraisal meeting of the “100-ton-per-year para-aramid pilot research” project organized by the association, three highly respected academicians of the Chinese Academy of Engineering in the textile industry were overjoyed. Yu Jianyong, a representative of the project undertaking unit and executive vice president of the Modern Textile Research Institute of Donghua University, said: “The technical results of the para-aramid fiber manufacturing pilot research project have been recognized by the appraisal expert committee. This is the reason why the project undertaking unit Shanghai Aimaida A generous gift from chemical fiber and scientific and technological personnel of Donghua University to the 17th National Congress of the Communist Party of China.”
Para-aramid is a new material indispensable for national economic construction and national defense construction. Since the domestic industry has not realized my country’s current annual import volume has reached more than 3,000 tons, and the variety, quantity, and price of supplies have long been at the mercy of others. For the sake of the national interest, Shanghai Aimaida Chemical Fiber and Donghua University undertook the pilot test task in the form of a combination of industry, learning and research. After completing the manufacturing of aramid raw materials in March this year – the pilot test of para-aramid polymer and solvent with an annual output of 100 tons, the company started non-stop spinning pilot research with an annual output of 100 tons.
During the implementation of the project, a team of old, middle-aged and young people was formed. There are old experts who have participated in the national “Sixth Five-Year Plan” and “Seventh Five-Year Plan” key aramid research and development projects, as well as Young Ph.D.s and M.S. They used self-polymerized raw materials, innovatively used twin-screw extruders and self-designed degassing devices, and successfully solved the key technologies of rapid dissolution of para-aramid polymers and rapid degassing of slurries, and also used independent The designed spinning device realizes continuous, multi-position, high-speed spinning of para-aramid fiber. The strength of the fiber exceeds 18cN/dtex, which is close to the level of foreign Kevlar29. Moreover, they also used a self-designed flat-plate heat treatment device to produce high-modulus para-aramid varieties, with a tensile modulus exceeding 700cN/dtex, which is close to the level of foreign Kevlar49. Experts attending the meeting unanimously believed that the complete set of equipment and process technology have reached the domestic level.
It is reported that my country’s para-aramid polymer and spinning project with an annual output of 2,000 tons is under construction.
