Lyocell fiber supply and demand have been growing at nearly 40% annually for the past two years, while nonwoven fabric output surpassed 9 million tons for the first time in 2025. These two figures signal that bio-based fibers are moving from laboratory concepts to large-scale commercialization. The bio-based chemical fiber industry chain collaboration exchange meeting held in Changshu in early August provided a footnote to this inflection. The core message: competitive focus is shifting from single-material performance to a full-chain green supply chain capability encompassing raw materials, technology, standards, and carbon footprint.
Industry Status: Structural Changes Behind the Data
The nearly 40% growth rate of Lyocell disclosed by the China Chemical Fibers Association is not an isolated phenomenon. It corresponds to the maturity of key technologies such as cellulose swelling and dissolution, and spinning forming, as well as the opening of high-value application scenarios in medical and hygiene materials. Meanwhile, nonwoven output has reached 9 million tons, with disposable hygiene products and wiping materials as the main demand drivers, making biodegradable raw material development a hotspot. These two lines together show that market acceptance of bio-based materials is shifting from 'green concept' to 'realistic choice with comparable performance and cost.'
However, this growth is not inclusive. Public industry data shows that the leapfrog development of bio-based fibers mainly occurred during the 14th Five-Year Plan period, but key monomers such as high-purity lactic acid, lactide, and furan dicarboxylic acid still rely on imports, and the localization rate of large-capacity continuous polymerization and melt direct spinning equipment needs improvement. This means that the current high growth is partly based on imported raw materials and equipment, and the degree of supply chain autonomy will determine the sustainability of growth in the next phase.
Technology Routes and Industrial Synergy: From Single-Point Breakthroughs to System Integration
The technology roadmap revealed at the meeting shows a shift from single-point breakthroughs to system integration. Academician Cheng Bowen's proposed full-chain research system of 'mechanism tracing—technology breakthrough—application and standards' is essentially a correction to the fragmented R&D model of the past. Researcher Wang Huaping from Donghua University predicted that bio-based and biodegradable fibers will maintain high growth in the coming years, but only if integrated design of processes and equipment is completed—meaning material innovation alone is insufficient; it must be coordinated with spinning equipment and finishing process upgrades.
Enterprise practices confirm this trend. Xinxiang Chemical Fiber's ionic liquid method thousand-ton production line is running stably, achieving non-derivatized green dissolution of cellulose; Jiangsu Sanlian New Material has launched functional bio-based polyester filaments with cooling effects through copolymerization modification. The common point: they are not simple material replacements but enhancements through modification and process control, making bio-based materials approach or even surpass traditional chemical fibers in performance. For buyers, this means a wider selection of bio-based fabrics, but requires re-evaluating suppliers' process stability and batch consistency.
Standards and Market Access: Green Capacity Becomes a Hard Threshold
The judgment of Zhang Qian from the China National Textile and Apparel Council is worth noting: green development has evolved from an environmental topic to a market access survival issue. International green trade rules are tightening, and the lack of standards for bio-based content determination, biodegradable fiber evaluation, and carbon footprint accounting will directly weaken the competitiveness of Chinese products in the global green supply chain. The association's 'Excellent Fiber Selection' project, through full-chain traceability and carbon footprint disclosure mechanisms, is essentially building a new quality credit system—not just a quality certificate but a passport to navigate green barriers in markets like the EU.
For foreign trade enterprises, this means green certification is no longer a bonus but a prerequisite for orders. In the next two years, more international buyers are expected to include carbon footprint reports and bio-based content certificates in procurement contracts. Factories need to accelerate energy structure transformation and incorporate green electricity and green chemicals into cost accounting models. Enterprises that establish carbon footprint management capabilities first will gain significant advantages in pricing and customer lock-in.
Raw Material Diversification and Sustainable Supply: Another Key to Unlocking Bottlenecks
The meeting emphasized raw material diversification: utilizing non-food biomass resources such as straw, corn cobs, Juncao, and bamboo to build a sustainable supply system. This is not only an environmental consideration to reduce oil dependence but also a supply chain security strategy. Currently, the localization rate of key monomers is insufficient, meaning raw material prices are susceptible to international commodity fluctuations. If raw material sources can be diversified, enterprises will gain stronger cost control and supply stability.
For domestic industrial clusters, this trend will bring new layout opportunities. Traditional textile clusters like Changshu and Shengze can leverage existing chemical fiber industry foundations to extend into bio-based raw material refining and modification; regions with agricultural waste resources may become new raw material supply nodes. The geographic distribution of the industry chain may be reshaped. Buyers should pay attention to the diversity and sustainability certification of suppliers' raw material sources when selecting partners.
