Lyocell fiber supply and demand have maintained a rapid growth rate of nearly 40% in the past two years, while nonwoven fabric output surpassed 9 million tons for the first time in 2025. These figures reveal a fact: bio-based materials are no longer a fringe experiment in the textile industry but are becoming a hard-core support for green transformation. At the 2026 Symposium on Collaborative Innovation Development of Bio-based Chemical Fiber and Raw Material Industry Chain held in Changshu, Jiangsu, industry experts and corporate representatives outlined a clear path from laboratory to market.
Current Status: Rapid Growth Amid Bottlenecks
The leapfrog growth of bio-based fibers is undeniable, but concerns remain beneath the surface. Key monomers such as high-purity lactic acid, lactide, and furandicarboxylic acid still rely on imports; large-capacity continuous polymerization and melt direct spinning technologies are not fully self-developed; and equipment localization is urgent. This means that despite strong terminal demand, upstream raw material 'chokepoints' continue to constrain cost reduction and supply stability. For buyers, the current price volatility of bio-based fabrics largely stems from uncontrollable upstream factors.
Diversifying raw materials is another essential path. Developing non-grain biomass resources such as straw, corn cobs, Juncao, and bamboo can not only alleviate the ethical pressure of 'competing with people for food' but also build a sustainable supply system. Jin Gaoling, vice president of the China Chemical Fibers Association, clearly pointed out this direction at the meeting, essentially moving bio-based fibers from 'niche environmental protection' to 'bulk industrial products'.
Technological Breakthroughs: A Full-Chain Approach from Mechanism to Application
On the technology front, the full-chain research system of 'mechanism tracing – technological breakthrough – application and standards' proposed by academician Cheng Bowen provides a clear focus for the industry. Breakthroughs in cellulose swelling and dissolution, Lyocell spinning, and other cutting-edge technologies are pushing Lyocell fibers into high-value fields such as medical and hygiene products. Wang Huaping, a researcher at Donghua University, predicted that bio-based and biodegradable fibers will maintain high growth rates in the coming years, significantly increasing the share of green fibers in the overall structure. This means that whoever masters core processes and integrated equipment design first will move from 'technically feasible' to 'market feasible'.
Corporate practices are equally noteworthy. Xinxiang Chemical Fiber's 'Shousai'er' thousand-ton production line is running stably, using ionic liquid method for non-derivatized green dissolution of cellulose. Yisheng New Materials optimizes polylactic acid fiber performance through copolymerization and blending modification, covering 3D printing and ecological fiber fields. Jiangsu Sanlian New Materials has launched a bio-based polyester filament matrix, integrating functions like cooling into green raw materials. These cases demonstrate that the value of bio-based materials has upgraded from a single environmental label to a composite competitiveness of appearance, performance, and sustainability.
Standards and Market: Green Capability Equals Market Access
The reminder from Zhang Qian, director of the Planning and Research Division of the Industry Department of the China National Textile and Apparel Council, is worth pondering: green development is not only an environmental issue but also a survival issue for market access. International green trade rules are becoming increasingly stringent; the lack of standards for carbon footprint accounting, bio-based content determination, and biodegradable fiber evaluation could become invisible barriers to exports. The association's 'Excellent Fiber Selection' project is building a full-chain traceability system and carbon footprint disclosure mechanism, essentially establishing a 'green passport' for the industry from fiber to garment.
In the nonwovens field, disposable hygiene products remain the largest application market, but the wiping materials market is growing rapidly, and the development of biodegradable raw materials has become a hotspot. Cui Meng, an associate professor at Beijing Institute of Fashion Technology, demonstrated PLA-based intelligent wound dressings and wearable sensors, indicating the cross-sector potential of bio-based materials in medical and health applications. These dynamics in sub-sectors mean richer product choices for buyers and urgency for factories to adjust processes and obtain certifications.
