While the global textile industry debates overcapacity and weak demand, China's fiber technology has quietly extended its track to the moon. The team led by Zhu Meifang at Donghua University has achieved the world's first continuous melt-spinning of simulated Chang'e-5 lunar soil, a breakthrough that not only sounds romantic but also proves the feasibility of extreme-environment materials moving from lab to deep-space applications. Behind this achievement lies a complete transformation of China's chemical fiber industry over the past four decades—from 'decent clothing' to 'strengthening the military and rejuvenating the nation.'
Data Behind the Industrial Shift
According to China Customs and industry public data, China's synthetic fiber output now accounts for over 70% of the global total, marking a historic leap in fiber quality from low to high. This quantitative change is underpinned by a thorough restructuring of technical pathways. The 'organic/inorganic hybrid fiber' concept proposed by Zhu's team integrates different materials at the nanoscale, achieving '1+1>2' multifunctional transmission and amplification. The technology has been fully industrialized in leading enterprises such as Hengyi, Defulen, and Hengshen, developing 15 categories of functional products including general fibers, smart fibers, protective materials, and high-performance carbon fibers, driving nearly 100 billion yuan in new output value for the industry.
From 'Bookshelf' to 'Shelf': The Commercialization Logic
'Research should not be built as a castle in the air'—this remark highlights the current pain point of industry-academia disconnect. Zhu's team's approach is to rapidly push lab results to production lines. Shortly after the Spring Festival this year, a senior Shanghai official visited Donghua University's National Science Park and urged faster pilot testing. The team responded by leveraging Songjiang District's 100-billion-yuan advanced materials industry cluster to establish the Songjiang Innovation Base of the State Key Laboratory of Advanced Fiber Materials. To date, 47 high-quality scientific projects are undergoing concept validation and pilot scale-up. For buyers, this means more high-performance fibers will transition from samples to stable industrial supplies, expanding domestic substitution options in the supply chain.
Extreme-Environment Materials: The Next Growth Pole
Targeting the frontier of brain science and intelligent interaction, the team has 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 hold great potential in medical monitoring and smart wearables. More striking is the 'lunar soil spinning' project—under simulated lunar vacuum and low-gravity conditions, the team independently designed a lunar-soil-simulant spinning apparatus and achieved continuous melt-spinning. Although far from commercialization, it validates the processability of fiber materials under extreme environments, providing key structural material support for future lunar base construction. For foreign trade enterprises, such technical reserves imply enhanced export competitiveness in high-value-added sectors like aerospace and defense.
Talent and Mechanisms: The Foundation of Innovation
Behind technical breakthroughs are talent pipelines and research mechanisms. Zhu has been teaching for over 30 years, insisting on delivering the 'first and last lectures' to undergraduates and proposing an 'immersive' education model that integrates disciplines and industry. Her team, with an average age of just over 30, has been selected as a key innovation team by the Ministry of Science and Technology. More importantly, the 'open competition' mechanism implemented at the Songjiang base focuses research resources on real problems. This institutional innovation is worth learning for SMEs—rather than spreading efforts thinly, concentrate on breaking through key links.
