A major national science award has thrust polyester fiber—the 'industrial staple' of the textile sector—into the industry spotlight. The 2025 National Science and Technology Progress First Prize was awarded to the project 'Key Technologies for Green and Intelligent Manufacturing in the Polyester Fiber Industry Chain,' led by Tongkun Group in collaboration with Donghua University, Zhejiang Sci-Tech University, and seven other units. This is not only the first time in years that the chemical fiber sector has claimed the top honor, but also signals that China's technological voice in the global polyester fiber chain has shifted from running alongside to leading.
Industry Impact Polyester fiber accounts for over 70% of China's total chemical fiber output, and China produces 70% of the world's chemical fibers. This scale means that even a one-percentage-point reduction in unit cost can generate billions of yuan in profit transmission downstream—from the grey fabric markets in Shengze to the textile distribution hubs in Keqiao. The project's pioneering PTA-PET direct coupling low-carbon manufacturing mode bypasses the traditional chip-spinning intermediate step, theoretically reducing comprehensive energy consumption per ton by more than 15%. For the razor-thin margins of conventional polyester filament markets, this is a quiet revolution.
More noteworthy is the breakthrough in intelligent manufacturing. The project achieved large-scale domestic substitution of DCS control systems, meaning that core automation equipment once reliant on imports—especially texturing machines and winders deployed in industrial zones like Tongxiang, Zhejiang, and Shengze, Jiangsu—will gradually be equipped with 'Chinese brains.' For equipment buyers, domestic substitution not only cuts procurement costs by 20%-30% but also shortens post-sales maintenance response times from weeks to days, significantly reducing downtime losses.
Regional and Chain Transmission From an implementation perspective, the project's results have been rolled out in three major industrial bases—Zhejiang, Jiangsu, and Xinjiang—and at more than ten industry units. Xinjiang, a hotspot for capacity transfers from the east, is leveraging its low electricity prices and policy incentives combined with this independent technology system to reshape the domestic polyester fiber capacity map. For fabric traders in Keqiao and Nantong, this means that within two years, differentiated polyester products from Xinjiang—such as cationic dyeable and high-elasticity yarns—will become more price-competitive, further compressing the cost advantages of traditional eastern production zones.
The project's other core breakthrough lies in the 'multi-head, multi-tail' series-parallel composite polymerization technology platform. This model allows different specifications of polyester fiber to be produced on the same line, enabling small-batch, multi-variety flexible manufacturing. This is highly beneficial for downstream buyers: past orders for conventional products required a minimum of 10,000 tons, but now orders as small as 1,000 tons or even 100 tons for differentiated products can be efficiently fulfilled. For apparel brands and fabric merchants working on quick-response orders, this flexibility directly shortens the window from sampling to mass production.
International Competition and Tech Barriers At the international level, the significance of this independent technology system is even deeper. The project has formed a complete intellectual property system with 76 authorized invention patents and 14 national and industry standards, cumulatively earning $1.8 billion in export revenue. Notably, breakthroughs in environmentally friendly titanium-based catalysts and green oiling technologies directly target tightening EU chemical regulations (e.g., REACH) and the Carbon Border Adjustment Mechanism. When European buyers begin requiring carbon footprint reports from suppliers, Chinese polyester fiber companies with full lifecycle green standards will gain a significant market access advantage.
Meanwhile, Professor Elsa Reichmanis, chair of the International Advisory Committee of Donghua University's State Key Laboratory for Advanced Fiber Materials, received the International Science and Technology Cooperation Award, sending a clear signal: China's textile technology is moving from 'importing' to 'two-way empowerment.' This three-time U.S. National Academy member has deeply engaged in Chinese graduate training and international conference organization, and her academic network will help Chinese fiber material standards gain faster international recognition.
