Lyocell fiber supply and demand have maintained a nearly 40% annual growth for two consecutive years, while nonwovens output surpassed 9 million tons for the first time. These two data points emerged simultaneously at an industry conference on bio-based fibers, sending a clear signal: green fibers have crossed from the concept-validation stage into a critical window for large-scale expansion.
Industry Landscape and Data Insights
At the recent symposium on bio-based chemical fiber and feedstock industry chain collaboration held in Changshu, Jiangsu, the China Chemical Fibers Association disclosed that bio-based fibers achieved leapfrog growth during the 14th Five-Year Plan period. However, the real test for the 15th Five-Year Plan lies in connecting the entire chain from key monomers to end-use applications. Currently, domestic large-scale production of high-purity lactic acid, lactide, and furandicarboxylic acid remains a bottleneck, while large-capacity continuous polymerization and melt direct spinning technologies are not yet fully mature, and localization of key equipment needs acceleration.
Meanwhile, downstream application markets are expanding rapidly. Data from the China Nonwovens & Industrial Textiles Association show that nonwovens output exceeded 9 million tons in 2025, with disposable hygiene products remaining the largest market, but wipes are seeing particularly fast demand growth, making biodegradable raw material development a hot topic. This suggests bio-based fibers will gain further penetration in industrial applications, not just in apparel fabrics.
Dual Breakthroughs in Technology and Standards
Academician Cheng Bowen of the Chinese Academy of Engineering systematically reviewed frontier technologies such as cellulose swelling and dissolution, and Lyocell spinning, proposing a full-chain research system covering "mechanism tracing, technology breakthrough, application, and standards." This approach directly addresses a key industry pain point: many laboratory achievements exist, but few can be stably mass-produced while meeting downstream performance requirements. Xinxiang Chemical Fiber's "Firstcell" thousand-ton production line, which uses ionic liquid method for non-derivatized green dissolution of cellulose, provides a replicable industrialization sample.
Standardization lag is another bottleneck. Industry associations are accelerating the formulation of standards for bio-based content determination, biodegradable fiber evaluation, and carbon footprint accounting, and have launched the "Excellent Fiber Selection" project to build a full-chain traceability system and carbon footprint disclosure mechanism. For buyers, this means more transparent quality and environmental data when selecting bio-based fabrics, rather than relying solely on supplier claims.
Policy Drivers and Market Access Pressures
Zhang Qian, director of the Planning and Research Division at the China National Textile and Apparel Council, emphasized that green development in textiles has evolved from an environmental issue to a matter of market access survival. Increasingly stringent international green trade rules, such as the EU's carbon border adjustment mechanism and sustainable product requirements, are forcing Chinese textile companies to translate low-carbon capabilities into core competitiveness in international markets. Companies that fail to build a full-chain green manufacturing system—covering green energy, green fibers, and green chemicals—will face invisible barriers in export markets.
This pressure is transmitting upstream. Wang Huaping, a researcher at Donghua University, predicted that bio-based chemical fibers and biodegradable fiber materials will maintain relatively high growth in the coming years, with the share of green fibers in the overall structure rising significantly. However, he cautioned that the industry needs to focus on core technologies and integrated process-equipment design to move from "technically feasible" to "market viable." In other words, only when cost and performance become comparable to conventional fibers can green fibers truly open large-scale substitution opportunities.
Corporate Practices and New End-Use Trends
Innovation at the enterprise level is no longer limited to material substitution but is shifting toward functional and scenario-based development. Yisheng New Materials optimizes the strength of polylactic acid fibers through copolymerization, blending, and process control, with products covering 3D printing and eco-fibers. Jiangsu Sanlian New Materials has launched a bio-based polyester filament product matrix with multiple functions such as cooling, achieving value upgrading from "green raw materials" to "functional fibers." Sun Mingliang, founder of the COOL-FRESH brand, proposed that fabric R&D should focus on collaborative innovation around consumer scenario emotions and composite functional needs, pushing bio-based materials from a single environmental attribute toward an integration of aesthetics, performance, and sustainability.
In medical and smart wearable fields, Associate Professor Cui Meng from Beijing Institute of Fashion Technology demonstrated the potential of PLA-based nanofibers in self-powered wearable sensors, ultrasonic-driven piezoelectric smart wound dressings, and humidity-pressure dual-mode smart wound dressings. Although these studies are still at the frontier, they indicate the possibilities of bio-based fibers in high-end functional markets, offering textile companies room for imagination in developing high value-added product lines.
