When lunar soil brought back by Chang'e-5 was drawn into continuous fibers, the technological boundary of China's fiber materials was rewritten again. Behind this achievement lies four decades of accumulation by Zhu Meifang's team at Donghua University—from tackling bottlenecks in civilian fibers to now supporting national manufacturing and deep-space exploration. China's chemical fiber industry has transformed from a follower to a leader in global share, with synthetic fiber output now accounting for over 70% of the world's total. The underlying logic of this shift is the material revolution brought by the 'organic/inorganic hybrid fiber' concept.
Technological Breakthroughs and Industrial Value
Hybridization is not simple mixing; it integrates different materials at the nanoscale to achieve '1+1>2' multifunctional transfer. Based on this concept, the team developed 15 functional products, including general fibers, smart fibers, protective materials, and high-performance carbon fibers, which have been fully industrialized in leading enterprises such as Hengyi, Defulen, and Hengshen, breaking foreign technical barriers and driving nearly 100 billion yuan in new output value. This means that Chinese fibers have shifted from 'low-quality, low-price' to 'functional, high-value,' offering buyers significantly increased options for domestic high-performance materials with improved cost and supply chain security.
More noteworthy is the breakthrough in frontier fields. The world's first continuous production line for hydrogel optical fibers, built by the team, enables precise control of fiber diameter and optical properties, providing a new material foundation for smart interactive and biomedical applications. The 'lunar soil spinning' exploration demonstrates the potential of fiber materials in extreme environments. By independently designing equipment to simulate lunar soil, the team achieved continuous melt-spinning, reserving key technology for future lunar base construction. These achievements are not just transformations from 'bookshelf to shelf' but also signify China's capability to define standards in specialty fibers.
Industrial Ecosystem and Regional Linkage
Technological landing relies on industrial ecosystem support. After the Spring Festival, Shanghai's top leaders visited Donghua University's Science Park, emphasizing acceleration of pilot testing and industrialization. Zhu's team subsequently established the Songjiang Innovation Base of the State Key Laboratory for Advanced Fiber Materials, focusing on AI, biomedicine, and extreme-environment materials, implementing a 'listing and commanding' mechanism. To date, 47 scientific innovation projects are undergoing concept validation and pilot scale-up. This layout's significance lies in bridging the gap between laboratory, pilot, and mass production, making regional industrial clusters (like Songjiang's billion-level advanced materials cluster) accelerators for technology transfer.
For downstream factories, this means shorter supply chain response times and more customization possibilities; for textile trading companies, domestic substitution of functional fibers will reduce dependence on imported high-end raw materials, especially amid current trade frictions, where supply chain resilience becomes a core competitive advantage.
Talent Development and Industry Foundation
Sustainability of technological breakthroughs depends on talent pipelines. Zhu has taught for over three decades, insisting on giving undergraduates the 'first lesson' and 'last lesson,' and serving as doctoral supervisor class teacher for 15 years. Her 'immersive' education model promoted Donghua's New Materials Industry College to be selected as one of the first national modern industry colleges. Her team, with an average age of just over 30, has been selected for multiple national innovation teams, becoming a 'whampoa' for industry technology output. This reminds the industry that competition in the fiber sector is ultimately competition for talent. Enterprises seeking long-term benefits should strengthen industry-academia integration and reserve new-generation technical backbone early.
