Lyocell fiber supply and demand have grown nearly 40% annually for the past two years, and nonwoven fabric output exceeded 9 million tons for the first time in 2025. These figures signal an acceleration of bio-based fibers moving from labs to production lines. The Bio-based Chemical Fiber and Raw Material Industry Chain Collaborative Innovation Development Exchange Meeting, held in Changshu, Jiangsu in early August 2026, highlighted this trend. The core takeaway: bio-based materials are no longer an environmental narrative but a prerequisite for entering global green supply chains.
Industry Data and Trends
At the meeting, the China Chemical Fibers Association reported that bio-based fibers achieved leapfrog growth during the 14th Five-Year Plan period. However, for the 15th Five-Year Plan, the industry faces structural challenges rather than growth issues. High-purity lactic acid, lactide, and furandicarboxylic acid—key monomers—still rely on imports. Large-capacity continuous polymerization and melt direct spinning technologies are not fully developed, and domestic replacement of critical equipment remains a bottleneck. This means that despite strong demand growth, unresolved core technology constraints will limit industrial scale in the long run.
The rapid growth of Lyocell fiber serves as a typical case. Supply and demand have maintained nearly 40% growth, but behind capacity expansion, process details like solvent recovery efficiency and spinning stability determine cost curves. Wang Huaping, a researcher at Donghua University, predicted that bio-based and degradable fibers will maintain high growth in the coming years, significantly increasing their share in the overall fiber mix. However, this premise depends on the industry transitioning from "technically feasible" to "market viable"—where cost, performance, and supply chain stability are simultaneously achieved.
Technological Breakthroughs and Supply Chain Coordination
The meeting revealed multiple technological breakthrough directions. Academician Cheng Bowen proposed building a full-chain research system covering "mechanism tracing, technology breakthroughs, application and standards," focusing on cellulose swelling and dissolution, and Lyocell spinning. Xinxiang Chemical Fiber has achieved non-derivatized green dissolution of cellulose using ionic liquid technology, with a stable thousand-ton production line. Yisheng New Materials optimizes polylactic acid fiber strength through copolymerization and blending modification, covering 3D printing and ecological fibers. These advances mean bio-based fibers are no longer simple material substitutes but are extending toward functional and differentiated applications.
Raw material diversification emerged as another key issue. The meeting proposed fully utilizing crop straw, corn cobs, fungus grass, and bamboo to build a sustainable supply system. This is not just a cost consideration but also a supply chain security issue—over-reliance on single food-based raw materials risks both "competition with grain for land" controversy and vulnerability to agricultural price volatility. For buyers, raw material source stability will directly affect bio-based fabric price expectations and delivery cycles.
Standards and Market Access
Zhang Qian, from the Industry Department of the China National Textile and Apparel Council, made a noteworthy statement: green development is not just an environmental issue but a market access survival issue. International green trade rules are becoming stricter, with carbon footprint accounting, bio-based content determination, and degradable fiber evaluation standards emerging as new trade barriers. The China Chemical Fibers Association's "Premium Fiber Selection" project, which establishes evaluation technical specifications, builds full-chain traceability systems, and carbon footprint disclosure mechanisms, essentially helps companies obtain a "green passport" for international markets.
For enterprises, this means green capability will directly translate into order competitiveness. Exporters lacking carbon footprint data or bio-based content certification may be excluded from procurement tenders in markets like the EU. Therefore, standards development is not optional industry self-discipline but a "hard threshold" determining market share.
Practical Recommendations
For Buyers - Prioritize suppliers with carbon footprint traceability and bio-based content certification to reduce future compliance risks. - Monitor capacity expansion of Lyocell and PLA, and use price fluctuation windows to lock in medium-term contracts. - Incorporate bio-based materials in fabric development, but evaluate performance differences versus traditional synthetics to avoid blind substitution.
For Foreign Trade Enterprises - Proactively build carbon footprint accounting systems to align with international green trade rules and avoid being shut out due to missing certifications. - Diversify raw material sources to mitigate supply chain risks and reduce dependence on single origins. - Collaborate with universities and research institutions to adopt mature technologies and shorten the transformation cycle from lab to market.
The race for bio-based fibers has begun. Whoever secures a position across technology, standards, and supply chain simultaneously will take the lead in the next cycle of green trade. For textile industry readers, it's time to move bio-based from "concept" to "budget."
