The industrialization of bio-based fibers is accelerating, and the numbers are telling: Lyocell fiber supply and demand have grown nearly 40% annually over the past two years, while nonwoven fabric output surpassed 9 million tons in 2025. This signals that green fibers are no longer just a concept but a tangible capacity and market reality.
A Turning Point for the Industry
From the leapfrog growth during the 14th Five-Year Plan period to the deeper push in the 15th Five-Year Plan, bio-based fibers are at a critical juncture, moving from technical validation to large-scale deployment. The roadmap outlined by Jin Gaoling, vice president of the China Chemical Fibers Association, at the Changshu meeting highlights that the industry will focus on achieving domestic large-scale production of key monomers such as high-purity lactic acid, lactide, and furandicarboxylic acid, while accelerating breakthroughs in large-capacity continuous polymerization and melt direct spinning. These technological advancements will directly impact the cost structure and supply stability of bio-based fibers, giving downstream buyers more controllable raw material sources and more competitive pricing.
Feedstock Diversification and Standardization
Diversification of feedstock is another key signal. The development and utilization of non-grain biomass resources such as straw, corncobs, juncao, and bamboo are changing the previous single dependence on petroleum-based raw materials. This shift is not just a resource strategy adjustment but also an enhancement of supply chain resilience. Meanwhile, the industry is accelerating the formulation of standards for bio-based content determination, degradable fiber evaluation, and carbon footprint accounting, aiming to build a competitive advantage for Chinese bio-based fiber products in the global green supply chain. The establishment of standards will directly affect the discourse power in international trade rules, and for export-oriented companies, aligning with these standards early is crucial to avoid future trade barriers.
From Lab to Market
The translation of technological breakthroughs into market applications is accelerating. Wang Huaping, a researcher at Donghua University, predicts that bio-based chemical fibers and biodegradable fiber materials will maintain a high growth rate in the coming years, with the share of green fibers in the overall structure rising significantly. However, he also points out that the industry needs to focus on core technologies, strengthen integrated process and equipment design, and push bio-based fibers from "technically feasible" to "market feasible." This means that technical superiority alone is not enough; cost control, scalable production capacity, and market acceptance are decisive factors for success.
Corporate practices offer diverse pathways. Xinxiang Chemical Fiber's "Shousai'er" thousand-ton production line is running stably, using ionic liquid technology for non-derivatizing green dissolution of cellulose; Yisheng New Materials is optimizing polylactic acid fiber performance through copolymerization and blending modification, covering fields such as 3D printing and ecological fibers; Jiangsu Sanlian New Materials has launched a bio-based polyester filament product matrix with multi-functional directions like cooling, achieving a value upgrade from "green raw materials" to "functional fibers." These cases illustrate that the application of bio-based materials is upgrading from a single environmental attribute to an integration of aesthetics, performance, and sustainability, meeting consumers' demand for composite functions.
The Survival Logic of Green Transformation
The reminder from Zhang Qian, director of the Planning and Research Department at the China National Textile and Apparel Council, is worth pondering: green development in the textile industry is no longer just an environmental issue but a matter of market access and survival. International green trade rules are becoming increasingly stringent, and companies that fail to build a full-chain green manufacturing system covering green energy, green fibers, and green chemicals risk being excluded from mainstream markets. Low-carbon capability is transforming into core competitiveness in international markets, and this trend is particularly pressing for small and medium-sized enterprises—they need to act early to avoid losing their position in the supply chain restructuring.
