Recently, the State Administration for Market Regulation (State Standardization Administration) issued Announcement No. 30 of 2026, which officially approved GB/T 47771-2026 "Terminology, Classification, and Model Compilation Methods for Polyacrylonitrile Fiber Production Complete Equipment" led by Zhejiang Jinggong Integrated Technology Co., Ltd. (referred to as "Jinggong Technology") and Zhejiang Huachuang Carbon Fiber Technology Co., Ltd. (referred to as "Huachuang Technology"), and will be implemented from February 1, 2027. This is another national standard implemented by Jinggong Technology in the field of carbon fiber core equipment, following the national standard for carbonization equipment.

The performance of carbon fiber is highly dependent on its precursor, polyacrylonitrile (PAN) precursor. The quality of raw silk directly determines the strength, stability, and lifespan of carbon fiber, while the accuracy and intelligence level of raw silk equipment directly affect the yield rate and production cost of mass production. It is the first core hurdle for domestic high-performance carbon fiber to achieve independent and controllable control of the entire industry chain. For a long time, there has been a lack of unified standards in the field of raw silk equipment in China, with equipment terminology, classification, and model naming being different, resulting in low efficiency in production line design, equipment procurement, process debugging, and industrial chain collaboration, which has hindered the breakthrough of large-scale production of high-performance raw silk.

Discussion and photo taking by the National Standard Setting Working Group

The national standard released this time focuses for the first time on complete sets of equipment for the production of polyacrylonitrile fibers, unifying the terminology, classification, and model preparation rules for the entire process from polymerization, spinning, stretching, drying to solvent recovery, and establishing an authoritative standard for the construction of domestic raw silk production lines, equipment research and development, and quality control. This standard fills the standardization gap in the field of complete sets of equipment for raw silk production, and solidifies the foundation for the standardized development of China's high-performance raw silk industry from the source. It has profound significance for improving the self-sufficiency rate of domestic high-performance carbon fiber, reducing industry chain costs, and ensuring the safety of strategic new material supply.

Previously, GB/T 44870-2024 "Terminology, Classification, and Model Preparation Methods for Fiber Carbonization Production Equipment" led by Jinggong Technology was officially implemented on June 1, 2025, comprehensively standardizing the technical requirements, testing methods, and inspection rules in the field of carbonization equipment. With the release of the new national standard for raw fiber equipment, the two key production processes of carbon fiber raw fiber and carbonization have all been included in the national standard map, and China's carbon fiber full process equipment now has a unified and interconnected standard system.

At this point, Jinggong Technology has mastered two core national standards in the field of carbon fiber, and has established a standardized system for carbon fiber complete equipment that connects the two key production processes of carbon fiber precursor and carbonization. Its industry benchmark position and technological leadership strength have once again obtained national authoritative certification. In addition, the company is also accelerating the layout of group standards - the group standard "Big Fiber Bundle Carbon Fiber" drafted by the company has recently passed expert review, which will provide more accurate technical specifications for product iteration and industrialization landing.

Huachuang Technology, as the collaborative drafting unit of this national standard, is the operating unit of the Zhejiang Province High Performance Carbon Fiber Equipment and Composite Materials Manufacturing Innovation Center. In 2025, it will be led by Jinggong Technology and jointly funded by several carbon fiber industry chain advantage enterprises such as Zhongying New Materials and Shenzhen Collaborative High tech. It is the first full chain innovation center in China's carbon fiber field that integrates "raw silk, carbonization, composite equipment manufacturing and product application". Currently, Huachuang Technology is accelerating the expansion of its shareholders and alliance units, fully promoting the creation of national innovation centers, and accumulating greater momentum for industrial technology innovation, achievement transformation, and ecological upgrading.

In the future, Jinggong Technology will continue to collaborate with Huachuang Technology, fully leverage the advantages of dual platform synergy, rely on the implementation and promotion of two national standards, synchronously promote the application and implementation of group standards, continuously tackle bottlenecks in large fiber bundles, high-performance PAN raw fibers, carbonization complete equipment and core processes, expand more key areas of composite materials and future industrial application scenarios, lead process technology iteration with standards, drive industrial chain upgrading with innovation, help China's carbon fiber industry chain to be safe and controllable, and seize the high ground of global new material industry competition.
