Bio-based fibers are moving from the laboratory's 'technical narrative' to the industry's 'capacity race.' Data revealed at the 2026 Bio-based Chemical Fiber and Raw Material Industry Chain Collaborative Innovation Development Exchange Conference tells the story: Lyocell fiber supply and demand have grown nearly 40% over the past two years, and nonwovens output surpassed 9 million tons in 2025. When green fibers shift from 'optional' to 'mandatory,' every link in the supply chain must recalibrate its position.
Background
The closed-door industry conference in Changshu, Jiangsu, was essentially a strategic alignment between the end of the 13th Five-Year Plan and the start of the 14th. Jin Gaoling, Vice President of the China Chemical Fiber Association, outlined clear directions: the industry must achieve domestic, large-scale production of key monomers like high-purity lactic acid, lactide, and furan dicarboxylic acid, while accelerating breakthroughs in large-capacity continuous polymerization and melt direct spinning. This means bio-based fiber competition has moved from 'existence' to 'cost and stability'—whoever achieves self-sufficiency in key raw materials gains pricing power.
Diversification of raw materials was also highlighted. Straw, corn cobs, Juncao, and bamboo were repeatedly mentioned, responding to concerns about competition with food crops. For buyers, different raw material routes will directly impact fiber carbon footprints and cost structures. In the coming years, bio-based fiber pricing may diverge significantly based on feedstock sources.
Industry Impact
The ultimate test of technological breakthroughs is market adoption. Wang Huaping, a researcher at Donghua University, predicted that bio-based and biodegradable fibers will maintain high growth, significantly increasing their share in the overall fiber mix. But a gap remains between 'technical feasibility' and 'market viability.' Practical cases shared by industry representatives show that polylactic acid fibers, through copolymerization and blending modifications, are upgrading from simple environmental attributes to composite functionalities like cooling and antibacterial properties. This means bio-based materials are no longer a sacrifice for greenness but are beginning to compete head-on with petrochemical fibers on performance.
Standardization is another 'hidden battlefield' repeatedly emphasized. The absence of standards for bio-based content determination, biodegradable fiber evaluation, and carbon footprint accounting has left many green claims unverifiable. Zhang Qian from the China National Textile and Apparel Council warned bluntly: green development is no longer just an environmental issue but a market access survival issue. For exporters, international green trade rules are tightening; products without carbon footprint data may not even make it to the exhibition floor.
The explosive growth of Lyocell fiber was a conference highlight. Xinxiang Chemical Fiber's 'Shousai'er' thousand-ton production line is running stably, using ionic liquid technology for non-derivatized green dissolution of cellulose. The nearly 40% supply-demand growth reflects accelerated substitution of imported Lyocell and a window for downstream home textile and apparel companies to switch suppliers. However, rapid growth also implies overcapacity risks; avoiding the pitfalls of viscose fiber overcapacity is a challenge the industry must address proactively.
