As the 'staple grain' of the textile industry, the technological level of the polyester fiber industry chain directly determines the quality and cost of downstream fabrics, garments, and home textiles. The 2025 National Science and Technology Award was announced, and a technical achievement led by Tongkun Group as the primary completing unit, in collaboration with ten research and industrial entities, won the first prize. This is not merely a ceremonial honor but a systematic validation of the technological path for the entire polyester fiber industry chain: the integration of green and smart manufacturing is becoming a new watershed for industrial competition.
Three Main Lines of Technological Breakthrough
The award-winning project achieved substantive breakthroughs in three dimensions across the full polyester fiber industry chain. First, in green manufacturing, the project pioneered a PTA-PET direct-coupling low-carbon manufacturing model and developed environmentally friendly titanium-based catalysts and engineering application technologies. This means energy consumption and emissions during production from raw materials to polymers will be significantly reduced. For an industry with an annual output of tens of millions of tons, even a one-percentage-point drop in unit energy consumption yields substantial cumulative carbon reduction. Additionally, the application of crude oil-based chemical fiber oils and green oiling technologies further reduces the environmental burden of production processes.
Second, in smart manufacturing, the project completed full-process automation equipment upgrades and achieved large-scale domestic substitution of DCS control systems. For a long time, the reliance on imported control systems for high-end chemical fiber production lines was a pain point. Domestic substitution not only lowers procurement costs but also enhances supply chain security. On this basis, the project established a smart manufacturing system for process and quality control, described as a replicable 'China solution,' meaning its technical architecture has cross-enterprise and cross-regional transfer value.
Third, in service model innovation, the project created a 'multi-head multi-tail' series-parallel composite polymerization technology platform, constructing a modular system for polymerization, spinning, and texturing processes. This flexible design enables differentiated customization of polyester fiber products and multi-regional collaborative agile manufacturing, meaning a single production line can quickly switch to produce different fiber specifications based on order demand, greatly improving market response speed and reducing inventory risk.
Industrial Implementation: Conduction Effects from Lab to Factory
The value of technological achievements ultimately manifests in actual benefits at the industrial level. Public information shows the project has formed an independent intellectual property system including 76 authorized invention patents, 10 software copyrights, and 14 national and industry standards. In terms of industrial promotion, the results have been applied in major chemical fiber production bases in Zhejiang, Jiangsu, and Xinjiang, as well as in more than 10 enterprises within the industry, leading to a significant reduction in energy consumption and defect rates.
For buyers and downstream fabric companies, this means the quality stability of upstream polyester fiber will further improve, batch-to-batch variation is expected to narrow, thereby reducing adjustment costs in subsequent processes. Additionally, enhanced modular customization capabilities make the supply of differentiated fibers more flexible, eliminating the need to pay excessive premiums for small batches of special specification fibers.
Tongkun Group, as the lead unit, has been selected as one of the first batch of national 'Zero-Waste Enterprise' typical cases due to the project's demonstration effect, and has been rated as a 'National Service-oriented Manufacturing Demonstration Enterprise' and 'National Excellent Smart Manufacturing Demonstration Factory.' These titles reflect the trend of transformation from pure manufacturing to a 'manufacturing + service' model, meaning companies not only sell fiber products but also export technical solutions and system services.
Industry Impact: A Key Variable Reshaping the Competitive Landscape
China's chemical fiber output accounts for 70% of the global total, with polyester products occupying the largest share. On such a large base, any technological upgrade will have global ripple effects. This award-winning technology system further consolidates China's technological leadership in the polyester fiber field. For international buyers, this means the cost-performance advantage of Chinese polyester fiber is no longer solely derived from scale effects and labor costs, but is now overlaid with hard technical barriers in green, low-carbon, and smart manufacturing.
From the industry chain conduction perspective, technological upgrades in upstream polyester fiber will directly impact midstream fabric weaving and dyeing processes. More stable fiber quality can reduce breakage rates during weaving, and greener fiber raw materials help downstream companies meet carbon footprint compliance requirements in markets like the EU. Furthermore, the promotion of domestic DCS system substitution will drive the growth of a group of domestic automation equipment and software service providers, forming a healthy industrial ecosystem.
