Bio-based Fibers on the Fast Track: Industrial Reshaping from Tech Breakthroughs to Green Supply Chains

When Lyocell fiber supply and demand have maintained a nearly 40% high growth rate in the past two years, and nonwovens output exceeded 9 million tons for the first time in 2025, bio-based fibers are no longer a laboratory concept but a real force reshaping the material structure of the textile industry. The 2026 exchange meeting on bio-based chemical fiber and raw material industry chain collaborative innovation, held in Changshu, Jiangsu, revealed these data, showing the industry chain a substantial acceleration of green transformation.

Event Background

The exchange meeting, led by the China Chemical Fibers Association, presented a complete picture of bio-based fibers from technical reserves during the 13th Five-Year Plan to leapfrog growth in the 14th Five-Year Plan. Jin Gaoling, vice president of the association, pointed out that for the 15th Five-Year Plan, the industry must solve the localization and scale preparation of key monomers such as high-purity lactic acid, lactide, and furan dicarboxylic acid, while accelerating breakthroughs in large-capacity continuous polymerization and melt direct spinning. This means that core raw materials and equipment that previously relied on imports are becoming the main direction for the next stage of industrial upgrading.

Raw material diversification has also entered the practical stage. Non-grain biomass resources such as straw, corncob, Juncao, and bamboo are explicitly identified as key to building a sustainable supply system. This responds to the principle of not competing with grain for land and reduces dependence on petroleum-based raw materials. Academician Cheng Bowen emphasized that bio-based materials are the material foundation for the green transformation of textiles, and developing them is an inevitable choice for achieving the 'dual carbon' goal. His proposed full-chain research system covering mechanism tracing, technology breakthroughs, applications, and standards provides a framework for collaborative innovation.

Industrial Impact

The scale application of bio-based fibers is reshaping the competitive logic of end markets. Wang Huaping, a researcher at Donghua University, predicted that the share of green fibers in the overall structure will increase significantly in the coming years, but to truly move from 'technically feasible' to 'market feasible,' the industry must strengthen integrated design of processes and equipment. This means that the environmental attributes of materials alone are no longer sufficient to win orders; enterprises need to simultaneously solve cost, performance, and supply chain stability issues. Cui Meng's presentation on polylactic acid-based nanofibers in wearable sensors and smart wound dressings revealed the potential for bio-based materials to penetrate high-value-added sectors.

For textile enterprises, green transformation has shifted from a moral appeal to a hard threshold for market access. Zhang Qian, director of the planning and research department at the China National Textile and Apparel Council, highlighted this trend: international green trade rules are tightening, and carbon footprint accounting and degradability evaluation standards will become 'passports' for exports. She emphasized that enterprises need to build a full-chain manufacturing system covering green energy, green fibers, and green chemicals to convert low-carbon capacity into actual competitiveness. This aligns with the association's 'Excellent Fiber Selection' project, which promotes full-chain traceability and carbon footprint disclosure mechanisms—future market competition will increasingly revolve around the completeness and transparency of green data chains.

Enterprise practices provide a footnote to these trends. Xinxiang Chemical Fiber's 'Shousai'er' thousand-ton production line is running stably, using ionic liquid technology for non-derivatized green dissolution of cellulose, marking the scale verification of domestic Lyocell technology. Jiangsu Sanlian New Material's bio-based polyester filament product matrix covering functions like cooling demonstrates a value upgrade path from 'green raw materials' to 'functional fibers.' Yisheng New Materials optimizes polylactic acid fiber performance through copolymerization and blending modifications, extending products to emerging fields such as 3D printing and ecological fibers. These cases show that the application scenarios of bio-based fibers are expanding from traditional textiles to medical, hygiene, and industrial fields, and a single environmental attribute is no longer sufficient—the composite upgrade of appearance, performance, and sustainability has become the new direction.

Practical Recommendations

For Buyers - Monitor the capacity expansion pace of bio-based fibers such as Lyocell and PLA, and use the nearly 40% supply-demand growth window to lock in medium- and long-term supply agreements to avoid cost risks from raw material price fluctuations. - Prioritize suppliers with carbon footprint disclosure capabilities and full-chain traceability systems to meet international buyers' green data audit requirements and avoid losing orders due to certification gaps.

For Foreign Trade Enterprises - Closely track changes in green trade rules in markets like the EU, and proactively prepare for certifications such as bio-based content determination and carbon footprint accounting, turning compliance costs into differentiated competitive advantages. - Gradually increase the proportion of bio-based fibers in exported products, especially in nonwovens and disposable hygiene products, responding to overseas market environmental demands with degradable raw materials.
