When Lyocell fiber supply and demand surged nearly 40% in two years, and nonwoven output exceeded 9 million tons for the first time, the green transformation of China's textile industry has moved beyond concept to become a real game of market access and global supply chain positioning. The 2026 exchange meeting on bio-based chemical fiber and raw material industry chain innovation, held in Changshu, signaled that bio-based materials are stepping from labs to production lines, transforming from eco-labels into core competitiveness.
Event Background
The meeting, spearheaded by the China Chemical Fibers Association, gathered academicians, university experts, and industry representatives to tackle the scaling bottlenecks of bio-based fibers. Vice President Jin Gaoling reviewed the 14th Five-Year Plan achievements, noting the industry's leapfrog growth, but for the 15th Five-Year Plan, the localization of key monomers like high-purity lactic acid, lactide, and furandicarboxylic acid remains a pain point. Breakthroughs in large-capacity continuous polymerization and melt direct spinning are urgent, along with domestic substitution of critical equipment. This means that raw materials and equipment previously reliant on imports are now bottlenecks for cost and capacity.
Feedstock diversification was repeatedly highlighted. Non-food biomass resources such as straw, corncob, fungus grass, and bamboo are seen as the foundation for a sustainable supply system. For buyers, this is not just an environmental narrative but a way to diversify price volatility risks—when oil-based raw materials fluctuate with international crude, bio-based alternatives offer another cost curve.
Industry Impact
The maturity of technology routes directly determines market acceptance. Academician Cheng Bowen detailed advances in cellulose swelling and dissolution and Lyocell spinning, outlining high-value applications in medical and hygiene materials. Wang Huaping from Donghua University predicted sustained high growth for bio-based and biodegradable fibers, with a rising share of green fibers. The logic: once "technically feasible" crosses to "market feasible," procurement lists downstream will see structural adjustments.
Industry data corroborates this trend. Zhang Zixin from the association noted nearly 40% growth in Lyocell supply and demand over two years, with the "Excellent Fiber Selection" project building a traceable closed loop from fiber to garment via evaluation standards and carbon footprint disclosure. In technical textiles, nonwoven output first exceeded 9 million tons in 2025, driven by disposable hygiene and wiping materials, making biodegradable feedstock a hot topic. For nonwoven and hygiene material plants, this means the window for upstream feedstock switching has opened.
Zhang Qian from the China National Textile and Apparel Council made a blunt assessment: green development has evolved from an environmental issue to a survival issue for market access. International green trade rules are tightening; without a whole-chain green manufacturing system covering green energy, green fibers, and green chemicals, insufficient low-carbon capability will become a hard barrier to exports. In other words, bio-based fiber deployment is essentially preemptive dismantling of future trade barriers.
Enterprise cases offer replicable paths. Xinxiang Chemical Fiber's ionic liquid method achieves non-derivatized dissolution of cellulose, with the "Shousail" thousand-ton line running stably, proving green dissolution technology has reached industrial scale. Jiangsu Sanlian New Materials launched bio-based polyester filament matrices with cooling and other functions, completing the value leap from "green feedstock" to "functional fiber." Yisheng New Materials optimizes PLA fiber strength through copolymerization and blending modification, expanding into 3D printing and eco-fibers. These cases show bio-based materials are no longer a niche selling point but a technical base supporting differentiated product lines.
