When synthetic fiber output accounts for over 70% of the global total, where does China's fiber industry go next? The answer may lie in lunar soil. A team led by Zhu Meifang at Donghua University has recently achieved continuous melt spinning of simulated Chang'e-5 lunar soil, a world first. This seemingly sci-fi exploration points to the application boundaries of fiber materials in extreme environments, and also provides new ideas for developing high-performance fibers on Earth.
The Dual Logic of Technological Breakthrough and Industrialization
The core contribution of Zhu Meifang's team is the concept of "organic/inorganic hybrid fibers," which fuses different materials at the nanoscale to achieve "1+1>2" multifunctional transmission. This concept has moved from lab to production line, fully implemented in leading enterprises such as Hengyi, Defulun, and Hengshen, developing 15 categories of functional products including general fibers, smart fibers, and protective materials. These products have broken foreign technical barriers and driven nearly 100 billion yuan in new industry output. This means the value of basic research lies not only in papers, but also in whether it can translate into actual competitiveness in the industrial chain.
Notably, the team has also built the world's first continuous production line for hydrogel optical fibers, achieving precise control over fiber diameter, mechanical properties, and optical performance. Such biocompatible fibers can be used in brain-computer interfaces and other frontier fields, and their industrialization will determine whether China can take the lead in the smart fiber sector. For buyers, this means the supply of functional fibers no longer relies on imports, significantly improving cost and delivery control.
The Last Mile from Lab to Industrial Belt
Shortly after the Spring Festival, Shanghai's top leaders visited the National University Science Park of Donghua University, urging acceleration of pilot testing and industrialization. The team then established the Songjiang Science and Technology Base of the State Key Laboratory of Advanced Fiber Materials, focusing on three tracks: artificial intelligence, biomedicine, and extreme-environment materials, implementing a "list-based leadership" mechanism. Currently, 47 projects are undergoing concept validation and pilot scale-up. The significance lies in leveraging Songjiang's 10-billion-yuan advanced materials industrial cluster, allowing researchers to directly connect with manufacturers and shorten the cycle from "bookshelf" to "store shelf."
For chemical fiber enterprises in the Yangtze River Delta, this industry-academia linkage means the channel for technological upgrading is widening. In the past, small and medium-sized enterprises often lacked independent R&D capabilities; now they can cooperate with the science base to obtain mature pilot solutions and reduce transformation risks. Meanwhile, the three tracks also signal that the incremental market for future fibers lies not in conventional apparel fabrics, but in high-value-added fields such as smart wearables, medical health, and extreme-environment equipment.
Industrial Impact: The Turning Point from Follower to Leader
China's fiber industry has long been in a "following" state. In the 1970s, people could hardly afford a decent shirt, but now synthetic fiber output accounts for over 70% of the global total. This transformation is attributed to researchers like Zhu Meifang who have spent decades tackling bottleneck problems. However, output leadership does not mean full technological leadership; gaps remain in high-end carbon fibers and special protective materials. The significance of lunar soil spinning lies in accumulating process data under extreme conditions, which can reversely promote the iteration of high-performance fibers on Earth.
For the textile industry, this means the competition logic is changing—from scale and cost to material innovation and functional added value. Foreign trade enterprises that still focus on conventional products will see shrinking profit margins; those that adopt new functional fibers early will gain premiums in differentiated markets. In addition, the maturity of biocompatible materials like hydrogel optical fibers may spawn new medical textile categories, opening a second growth curve for the industry.
