The awarding of a First Prize of National Science and Technology Progress is rewriting the competitive rules of China's polyester fiber industry. The 'Green and Intelligent Manufacturing Key Technologies for Polyester Fiber Industry Chain' project, completed by Donghua University in collaboration with leading enterprises such as Tongkun Group, won the top prize at the 2025 National Science and Technology Award Conference. This is not just a footnote to university research capabilities but marks a critical shift from scale leadership to technology dominance in the chemical fiber sector.
Technological Breakthrough and Industrial Deployment
The project team's pioneering 'one head, three tails' multi-point addition large-scale polymerization-spinning-drawing modular digital linkage platform has unblocked key bottlenecks in the green, intelligent, and agile manufacturing of the entire polyester fiber industry chain. From a technical system perspective, the project has generated 76 invention patents, 10 software copyrights, and 14 national/industry standards, building a complete moat of independent intellectual property. The industrialization results are more tangible: the technology has been deployed in national chemical fiber industrial bases across Zhejiang, Jiangsu, and Xinjiang, covering over 10 leading enterprises, with cumulative new sales exceeding 200 billion RMB, profits and taxes over 10 billion RMB, and export earnings of 1.8 billion USD. This means the chemical fiber industry is no longer just reliant on capacity accumulation but is driven by technology value-added growth.
Industry Significance and Strategic Value
Polyester fiber is known as the 'industrial staple food' of the textile industry. China accounts for 70% of global chemical fiber capacity, with polyester fiber production ranking first. However, the industry has long suffered from high energy consumption, weak flexible manufacturing capabilities, and insufficient independent control of the industry chain. This technological breakthrough alleviates the 'grain-cotton land conflict' at the source, significantly reduces industry energy consumption and product defect rates, stabilizes the domestic chemical fiber chain, and effectively prevents the risk of industrial relocation. For buyers, this means significantly improved upstream supply chain stability and more consistent product quality. For foreign trade enterprises, the independent intellectual property system enhances confidence in dealing with international trade barriers.
International Collaboration and Academic Impact
Concurrent with the First Prize, Elsa Reichmanis, Chair of the International Advisory Committee of the State Key Laboratory for Advanced Fiber Materials at Donghua University, received the International Science and Technology Cooperation Award. She has long engaged in academic exchanges, joint research, and talent training with Donghua University, leading the establishment of an international platform for advanced fiber materials. This award not only recognizes her individual contributions but also signals a new level of international collaboration in China's advanced fiber materials discipline. For the industry, deep involvement of top global scholars will accelerate the transformation of cutting-edge basic research into industrial technology, shortening the cycle from lab to production line for high-performance fibers.
Industry Impact and Trend Judgment
The simultaneous landing of two national-level awards at Donghua University is a concentrated reflection of the university's long-term focus on its distinctive textile and fiber materials disciplines. Domestically, the university collaborates with industry leaders like Tongkun Group to empower traditional manufacturing transformation through technological innovation. Internationally, it attracts top global scholars to build joint research platforms, bridging cutting-edge basic research and international exchange. This 'deep integration of industry, academia, and research, with two-way opening at home and abroad' research path is reshaping the competitive landscape of the chemical fiber industry. In the future, the industry will increasingly focus on core tracks of new fiber materials, intelligent textiles, and green manufacturing, with technology-driven enterprises gaining higher bargaining power and market position.
