When Lyocell fiber grows at nearly 40% annually, competition in bio-based fibers is no longer about technical verification but a triple contest of cost, scale, and standards. Signals from the 2026 symposium on bio-based chemical fiber and feedstock industry chain collaboration are clear: whoever first achieves localization of key monomers such as high-purity lactic acid, lactide, and furandicarboxylic acid will take the lead in the upcoming restructuring of green supply chains.
Event Background
The closed-door industry meeting in Changshu, Jiangsu, unusually brought together academicians, university researchers, industry associations, and leading enterprises, with discussions directly targeting bottlenecks in moving bio-based fibers from labs to production lines.靳高岭, vice president of the China Chemical Fibers Association, portrayed an industry that achieved leapfrog growth during the 14th Five-Year Plan period. However, for the 15th Five-Year Plan, the industry must solve the "chokepoint" in raw materials—localized large-scale preparation of monomers like high-purity lactic acid, lactide, and furandicarboxylic acid, as well as breakthroughs in large-capacity continuous polymerization and melt direct spinning. This implies that the previous reliance on imported intermediates is changing, and feedstock diversification (straw, corncob, Juncao, bamboo) becomes key to building a sustainable supply system.
Academician Cheng Bowen of the Chinese Academy of Engineering delved into the underlying technology, emphasizing breakthroughs in cellulose swelling/dissolution and Lyocell spinning, and proposed a full-chain research system of "mechanism tracing—technology breakthrough—application and standards." This system elevates bio-based fibers from a single material issue to a systematic project covering high-value applications such as medical and hygiene products. Wang Huaping, a researcher at Donghua University, predicted more directly that bio-based chemical fibers and biodegradable fiber materials will maintain high growth in the coming years, with the share of green fibers in the overall structure rising significantly—but only after achieving the leap from "technically feasible" to "market feasible."
Industry Impact
Data is confirming this trend. Zhang Zixin, director of the Science and Technology Department of the China Chemical Fibers Association, revealed that Lyocell fiber supply and demand have maintained nearly 40% high growth over the past two years. The association's "Premium Fiber Selection" project has begun building a full-chain traceability system and carbon footprint disclosure mechanism. Behind this is the rigid demand from downstream brands for verifiable green attributes, meaning buyers are no longer satisfied with "claimed eco-friendliness" but require data backing at every stage from fiber to garment. Meanwhile, data from the China Nonwovens & Industrial Textiles Association shows that nonwoven fabric output surpassed 9 million tons for the first time in 2025. Disposable hygiene products remain the largest application market, but the rapid expansion of the wiping materials market and rising interest in biodegradable raw materials are reshaping the material structure of industrial textiles.
Zhang Qian, director of the Planning and Research Division of the Industry Department of the China National Textile and Apparel Council, warned that green development has evolved from an environmental issue to a market access survival issue. Tightening international green trade rules mean carbon footprint accounting, bio-based content determination, and other standards are no longer just technical documents but "passports" to Western markets. This implies that export-oriented textile enterprises that fail to start building a full-chain layout of green energy, green fibers, and green chemicals this year may face order loss risks in the future.
Enterprise practices also reveal a shift in competitive focus. Xinxiang Chemical Fiber achieved non-derivatized green dissolution of cellulose via ionic liquid technology, with its "Shousail" thousand-ton production line running stably. Yisheng New Materials optimized polylactic acid fiber strength through copolymerization and blending modification, covering 3D printing and eco-fiber fields. Jiangsu Sanlian New Material extended bio-based polyester filaments to multi-functional directions such as cooling. The common thread: bio-based materials are shedding the stereotype of "eco-friendly but poor performance" and upgrading toward an integration of aesthetics, performance, and sustainability. Sun Mingliang, founder of the COOL-FRESH brand, emphasized "collaborative innovation based on consumer scenario emotions and composite functional needs," which essentially highlights the next step in market education—making end users pay for green value rather than letting cost pressure fall entirely on the upstream chain.
