With Lyocell fiber supply and demand growing at nearly 40% annually and nonwoven output surpassing 9 million tons for the first time, bio-based fibers have moved from laboratory concepts to the hardcore support of the textile industry's green transformation. The 2026 symposium on bio-based chemical fiber and raw material industry chain innovation, held in Changshu, Jiangsu, sent a clear signal: the industry is transitioning from 'technical feasibility' to 'market viability,' with localization of key monomers and standardization becoming the decisive factors.
Background
Data revealed at the conference painted a booming picture for bio-based fibers. Zhang Zixin, director of the Science and Technology Department of the China Chemical Fibers Association, noted that Lyocell fiber supply and demand have maintained nearly 40% high growth in the past two years. Meanwhile, Li Guanzhi, deputy director of the Science and Technology Development Department of the China Nonwovens & Industrial Textiles Association, disclosed that China's nonwoven output exceeded 9 million tons in 2025, with disposable hygiene products remaining the largest application market, but wipes expanding rapidly and biodegradable raw materials becoming a hotspot. These figures reflect genuine downstream demand for green fibers, not policy-driven hype.
Jin Gaoling, vice president of the China Chemical Fibers Association, reviewed the industry's progress during the 14th Five-Year Plan period, noting significant growth, but stressed that for the 15th Five-Year Plan, the industry must achieve localized, large-scale production of key monomers such as high-purity lactic acid, lactide, and furandicarboxylic acid, while accelerating breakthroughs in large-capacity continuous polymerization and melt direct spinning, and promoting domestic substitution of key equipment. This means that core raw materials and equipment previously dependent on imports are becoming the next breakthrough points; whoever achieves localization first will gain the initiative in cost and supply chain security.
Industry Impact
The scale-up of bio-based fibers is reshaping the raw material structure and competitive logic of the textile industry. Academician Cheng Bowen analyzed frontier technologies such as cellulose swelling and dissolution and Lyocell spinning, proposing a full-chain research system from mechanism tracing to technology breakthroughs, applications, and standards. The core of this system is to unblock the path from basic research to industrial application. Wang Huaping, a researcher at Donghua University, predicted that bio-based chemical fibers and biodegradable fiber materials will maintain high growth in the coming years, significantly increasing their share in the overall fiber structure. He also reminded that the industry needs to focus on core technologies, strengthen integrated process and equipment design, and push bio-based fibers from 'technical feasibility' to 'market viability.'
For buyers and factories, this means fundamental changes in supply chain choices. Zhang Qian, director of the Planning and Research Department of the China National Textile and Apparel Council, emphasized that green development is no longer just an environmental issue but a market access survival issue. With increasingly strict international green trade rules, companies that fail to build a full-chain green manufacturing system covering green energy, green fibers, and green chemicals risk being excluded from mainstream markets. In other words, low-carbon capability is no longer a bonus but a ticket to entry. For SMEs relying on traditional chemical fibers, this transformation pressure is particularly acute, but it also opens a window for differentiated competition.
Enterprise practices already provide replicable paths. Xinxiang Chemical Fiber's 'Shousai'er' thousand-ton production line uses ionic liquid technology for non-derivatized green dissolution of cellulose, running stably and validating engineering feasibility. Yisheng New Materials optimizes polylactic acid fiber strength through copolymerization, blending, and process control, covering 3D printing and ecological fiber fields. Jiangsu Sanlian New Materials has launched a bio-based polyester filament product matrix with multidimensional functions like cooling, achieving value upgrading from 'green raw materials' to 'functional fibers.' These cases show that bio-based fiber applications are shifting from simple environmental substitution to a composite track combining functionality and sustainability.
Practical Recommendations
For Buyers - Prioritize suppliers with carbon footprint disclosure and full-chain traceability, such as those certified by the association's 'Youpin Xianxuan' project, to ensure compliance with international green trade rules. - Monitor supply-demand dynamics of Lyocell and PLA, leveraging the nearly 40% growth window to lock in long-term agreements and avoid price volatility. - Integrate bio-based fibers into early product R&D design, aligning with consumer demands for aesthetics, performance, and sustainability, to avoid costly later substitutions.
For Foreign Trade Companies - Proactively develop carbon footprint accounting and green certifications, benchmarking against EU and other market access standards, to turn low-carbon capability into international bargaining power. - Track the localization progress of key monomers, adjust procurement strategies timely to reduce dependence on imported raw materials, and enhance supply chain resilience. - Leverage the growth potential of nonwovens in emerging markets like wipes, developing biodegradable raw material products to seize niche opportunities.
The wave of bio-based fiber industrialization has arrived, but the real watershed lies in the speed of technological breakthroughs and the leadership in standard-setting. For every participant in the textile value chain, now is the critical moment to reposition and secure a place in the future.
