Recently, the basic information of the energy-saving report for the 40,000 tons/year high-performance PAN fiber project of Zhejiang Jinggong Carbon Materials Technology Co., Ltd. has been publicized.

It is reported that the total investment in the project is 1.984 billion yuan, covering an area of 201.5 acres. The construction content of the project includes 8 high-performance polypropylene fiber production lines, with acrylonitrile as the raw material and dimethyl sulfoxide as the solvent. The acrylonitrile raw material is polymerized using a one-step method to form the spinning solution of polyacrylonitrile, which is processed using a dry-jet wet spinning technique. This involves steps such as coagulation bath, washing, oiling, drying, air finishing, and steam stretching, resulting in the production of high-performance PAN fiber, which is a raw material for carbon fiber. Upon completion of the project, it will have an annual production capacity of 40,000 tons of high-performance PAN fiber tow.

It is worth mentioning that these high-performance precursor fibers are not ordinary products; they are the key raw materials for producing T700 and T800 grade PAN-based carbon fibers. T700 and T800 grade PAN-based carbon fibers have indispensable applications in many high-end fields, such as the aerospace sector, which has extremely high requirements for material strength, lightweight properties, and other performance characteristics.

According to the company's announcement on September 30, 2024, Jinggong Technology plans to invest in the construction of a high-performance fiber project through its wholly-owned subsidiary Jinggong Carbon Materials, with an estimated investment of 669 million yuan. The project intends to build two high-performance fiber production lines, and upon completion, it will have an annual production capacity of 10,000 tons of high-performance fiber, with plans to commence production in June 2025.

The announcement shows that Zhejiang Jinggong Carbon Materials' long-term plan aims to achieve an annual production capacity of 40,000 tons of high-performance PAN fiber, with the construction of eight high-performance polyacrylonitrile fiber production lines.

It is worth mentioning that recently, the Zhejiang Provincial Department of Economy and Information Technology announced the "List of Cultivation and Construction of Zhejiang Provincial Manufacturing Innovation Centers," and Jinggong Technology's "Zhejiang High-Performance Carbon Fiber Equipment and Composite Materials Manufacturing Innovation Center" was successfully selected. This is the first full-chain innovation center in the carbon fiber field nationwide that integrates "precursor, carbonization, composite equipment manufacturing, and product application."
