At the 2025 National Science and Technology Awards ceremony, the textile and chemical fiber sector made a rare double win: a first prize for scientific and technological progress and an International Science and Technology Cooperation Award. The former focuses on the autonomous technology system of the polyester fiber industry chain, while the latter honors an American engineering academician who has long promoted Sino-US scientific exchanges. This signals that China's chemical fiber industry has shifted from single-point breakthroughs to a systemic, self-reliant framework and is beginning to play a core role in the global innovation network.
Green and Smart: The Dual Drivers of Polyester Fiber
The project that won the first prize, "Key Technologies for Green and Intelligent Manufacturing in the Polyester Fiber Industry Chain," was led by Tongkun Group in collaboration with ten institutions including Donghua University and Zhejiang Sci-Tech University, after over a decade of research. Polyester fiber, the 'industrial staple' of textiles, accounts for more than 70% of China's chemical fiber output, and its upgrade directly impacts the cost and quality of downstream fabrics and garments.
The project's core breakthroughs are in three dimensions: green manufacturing, smart manufacturing, and service-oriented manufacturing. In the green dimension, the team pioneered a PTA-PET direct coupling low-carbon model and developed environmentally friendly titanium-based catalysts to replace traditional antimony catalysts, reducing heavy metal pollution at the source. In the smart dimension, they achieved domestic substitution of DCS control systems, meaning factories no longer rely on imported industrial control systems, enhancing data security and customization capabilities. Service-oriented manufacturing, through a 'multi-head, multi-tail' polymerization platform, allows a single production line to simultaneously produce multiple differentiated products, enabling flexible supply for small batches and diverse varieties. For fast fashion and functional fabric buyers, this means shorter lead times and lower minimum order quantities.
To date, the technology has generated 76 authorized invention patents and 14 national and industry standards, and has been deployed in industrial bases in Zhejiang, Jiangsu, and Xinjiang. Public data shows cumulative new sales exceeding 200 billion RMB, with profits and taxes over 10 billion RMB and export earnings of 1.8 billion USD. For buyers, this means that companies adopting this technology system offer products with stronger competitiveness in cost, delivery, and environmental compliance.
International Cooperation Award: From Technology Import to Talent Co-cultivation
The International Science and Technology Cooperation Award, announced alongside the first prize, was granted to Professor Elsa Reichmanis of Lehigh University. A top scholar in semiconductor materials, she has collaborated deeply with Donghua University's State Key Laboratory for Advanced Fiber Materials since 2013, co-supervising graduate students, publishing 18 high-level papers, and chairing multiple international fiber conferences.
The significance of this award is that it recognizes a mutually beneficial cooperation model: Chinese universities provide international scholars with large-scale application scenarios and industrialization platforms, while international scholars bring cutting-edge research methodologies and global academic networks. For the textile industry, this means fiber material R&D is no longer limited to traditional process improvements but begins to incorporate interdisciplinary thinking from semiconductors and flexible electronics, laying the technical foundation for new tracks like smart textiles and wearable devices.
Transmission Effects on the Industry Chain
The simultaneous appearance of both awards has direct implications for upstream and downstream players in at least three ways:
- **For upstream chemical fiber companies**: The standardization and modularization of the technology system lower the technical threshold for building or retrofitting production lines. Small and medium-sized chemical fiber companies can quickly achieve green and smart upgrades by purchasing technology licenses or joining industry alliances, avoiding being left behind by leading firms.
- **For midstream fabric and weaving mills**: Enhanced customization capabilities for polyester fiber mean fabric mills can respond more flexibly to brand-specific requirements, such as specific hand feel, quick-dry, or antibacterial functions, without relying on imported specialty fibers.
- **For foreign trade enterprises**: Export earnings data already prove the competitiveness of products from this technology system in international markets. Especially as the EU's Carbon Border Adjustment Mechanism (CBAM) gradually takes effect, full life-cycle green standards will become an invisible threshold for exports.
