When lyocell fiber supply and demand have maintained nearly 40% growth for two consecutive years, bio-based fibers are no longer a laboratory concept but a real force reshaping the textile raw material landscape. The 2026 Symposium on Collaborative Innovation Development of Bio-based Chemical Fiber and Raw Material Industry Chain held in Changshu, Jiangsu, sent a clear signal: the industry is shifting from the 'first half' of technological breakthroughs to the 'second half' of market deployment. Whether it can cross the threshold of key monomer localization and equipment self-sufficiency will determine who occupies a leading position in the global green supply chain.
Data Behind the Turning Point
Data disclosed by the China Chemical Fibers Association outlines a clear growth curve: lyocell fiber supply and demand have grown by nearly 40% in the past two years, and nonwovens output surpassed 9 million tons in 2025, with disposable hygiene products and wipes as the main application markets. These figures indicate that bio-based fibers have the foundation for large-scale expansion, and the rising demand for biodegradable raw materials in the nonwovens sector opens new outlets for upstream bio-based fibers.
It is worth noting that growth is not uniform. Meeting information suggests that bio-based chemical fibers and biodegradable fiber materials will maintain high growth rates in the coming years, and the share of green fibers in the overall structure will increase significantly. For buyers, this means more diverse supply options, but also a need to guard against quality variability during rapid expansion—a period often marked by standard gaps. Downstream companies should pay more attention to suppliers' technological maturity and quality control systems.
Dual Challenges of Technical Bottlenecks and Industrial Synergy
Despite the optimistic outlook, the industry faces obvious hard constraints. Jin Gaoling, vice president of the China Chemical Fibers Association, pointed out that during the '15th Five-Year Plan' period, the industry needs to promote the localized large-scale preparation of key monomers such as high-purity lactic acid, lactide, and furan dicarboxylic acid, accelerate breakthroughs in large-capacity continuous polymerization and melt direct spinning, and push for domestic substitution of key equipment. This directly highlights the 'bottleneck' links in the bio-based fiber industry chain—upstream raw materials and core equipment still partially depend on imports, keeping costs high and weakening competitiveness against petroleum-based fibers.
Raw material diversification is another path. Fully utilizing straw, corn cob, fungus grass, bamboo, and other resources can reduce dependence on food crops and build a more sustainable supply system. Academician Cheng Bowen's proposed full-chain research system of 'mechanism tracing—technology breakthrough—application and standards' aims to unblock bottlenecks from the basic research end. Wang Huaping, a researcher at Donghua University, emphasized that the industry needs to strengthen the integrated design of processes and equipment to push bio-based fibers from 'technically feasible' to 'market feasible.' These judgments point to the same core: the competitiveness of bio-based fibers lies not only in the 'green' label but also in whether they can engage in a direct dialogue with traditional fibers in terms of performance and cost.
From Raw Materials to End-Use: How to Monetize Green Value
Zhang Qian, director of the Planning and Research Division of the Industry Department of the China National Textile and Apparel Council, offered a thought-provoking reminder: the green development of the textile industry is no longer just an environmental issue but a matter of market access survival. With increasingly stringent international green trade rules, companies that fail to build a full-chain green manufacturing system covering green energy, green fibers, and green chemicals will struggle to translate low-carbon capabilities into core competitiveness in international markets. This means that procurement decisions for bio-based fibers are no longer simple 'material substitutions' but a reassessment of the entire supply chain's carbon footprint.
Enterprise practices already provide reference samples. Xinxiang Chemical Fiber's 'Shousai'er' thousand-ton production line is running stably, using ionic liquid technology for non-derivatized green dissolution of cellulose; Yisheng New Materials optimizes polylactic acid fiber performance through copolymerization and blending modification, expanding products into 3D printing and ecological fibers; Jiangsu Sanlian New Materials has built a bio-based polyester filament product matrix with multidimensional functions including cooling. These cases show that bio-based materials are upgrading from a single environmental attribute to an integration of aesthetics, performance, and sustainability—the key to winning over end consumers.
Standard Building: Competing for Green Discourse Power
Another important signal from the meeting is the urgency of standard building. Accelerating the formulation of standards for bio-based content determination, biodegradable fiber evaluation, and carbon footprint accounting is not only for market regulation but also to build competitive advantages in the global green supply chain. The association's 'Youpin Xianxuan' project, through evaluation technical specifications and full-chain traceability systems, attempts to establish a quality closed loop from fiber to garment. For export companies, this directly affects whether products can meet green access requirements in markets like the EU.
In the coming years, bio-based fibers will enter a critical period of 'race between technological maturity and market acceptance.' Upstream companies need to continue investing in monomer localization and equipment substitution; midstream fabric manufacturers should focus on differentiation opportunities brought by functional modification; and end brands need to convert green attributes into perceivable consumer value. Those who first close the loop of 'raw materials—technology—standards—market' will take the lead in the next round of global textile competition.
