Bio-based Fibers at the Pre-Scale-Up Stage: Localization of Raw Materials and Standard Building as Key Battlegrounds

A set of data reflects the temperature of the bio-based fiber track: Lyocell fiber supply and demand have maintained a nearly 40% annual growth rate, and nonwoven fabric output exceeded 9 million tons for the first time in 2025. Behind these figures lies the real pulse of the textile industry's green transformation moving from concept to implementation. At the 2026 Symposium on Collaborative Innovation and Development of Bio-based Chemical Fiber and Raw Material Industry Chain, the consensus among industry, academia, and research was that material hard support is on the eve of scale-up, but the real race point lies in raw material localization and standard discourse power.

Event Background

The closed-door seminar held in Changshu, Jiangsu, gathered the Chemical Fiber Association, academicians, university research teams, and leading enterprise representatives. The core signal released at the meeting was not a simple technology showcase but a collective calibration of the industry path for the "15th Five-Year Plan" - the industry should promote the localized large-scale preparation 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 technology. This means that core raw materials that previously relied on imports are becoming targets for local supply chain breakthroughs.

Raw material diversification was also put on the agenda. Non-food biomass resources such as straw, corncob, Juncao, and bamboo are regarded as the cornerstone of a sustainable supply system. For buyers, this is not only a cost issue but also a consideration of supply chain resilience - when corn prices fluctuate or international logistics are blocked, diversified raw material channels can effectively hedge risks.

Industry Impact

The divergence of technological routes is reshaping the competitive landscape. Academician Cheng Bowen's full-chain research system of "mechanism tracing - technology breakthrough - application and standards" directly points to the industry pain point: bio-based fibers cannot stay at the laboratory level of "technically feasible"; they must cross to "market feasible." Researcher Wang Huaping from Donghua University predicted that the share of green fibers will increase significantly in the coming years, but the premise is that integrated design of process and equipment must keep up.

Enterprise practices have shown signs. Xinxiang Chemical Fiber's "Shousai'er" thousand-ton production line operates stably, using ionic liquid method to achieve non-derivatized green dissolution of cellulose; Yisheng New Materials optimizes polylactic acid fiber performance through copolymerization and blending modification, extending products to 3D printing; Jiangsu Sanlian New Materials builds a bio-based polyester filament matrix around functional directions such as coolness. These cases indicate that bio-based materials are upgrading from a single environmental label to a composite value of "appearance, performance, and sustainability."

Standard building has become another invisible track. Zhang Qian, director of the Planning and Research Department of the China National Textile and Apparel Council, emphasized that green has shifted from an environmental issue to a survival issue for market access. With increasingly stringent international green trade rules, standards such as carbon footprint accounting, bio-based content determination, and biodegradable fiber evaluation will directly determine whether products can enter high-end supply chains in Europe and the US. The association's "Excellent Fiber Selection" project, which promotes full-chain traceability and carbon footprint disclosure mechanisms, is precisely a compliance bridge for export enterprises.

For downstream buyers, the scale-up of bio-based fibers means more choices but also brings verification challenges. Currently, products labeled "bio-based" are mixed, lacking unified certification. As the standard system improves, procurement logic should shift from "looking at names" to "checking carbon footprints" - suppliers who can provide complete life cycle data and pass third-party certification are the real long-term partners.

Practical Recommendations

For Buyers - Prioritize suppliers that have established carbon footprint disclosure mechanisms and participate in traceability projects such as "Excellent Fiber Selection" to ensure verifiable green attributes. - Monitor the capacity expansion rhythm of Lyocell, polylactic acid, and other categories, and lock in long-term contracts at low price points to hedge raw material fluctuations. - Include bio-based content, biodegradability, and other indicators in procurement contracts, and require third-party test reports to avoid concept hype.

For Foreign Trade Enterprises - Benchmark against carbon footprint accounting rules in markets such as the EU in advance, and establish product life cycle databases to avoid green barriers caused by standard non-compliance. - Pay attention to the supply chain layout of non-food raw materials such as straw and Juncao, and use diversified sources to reduce export compliance risks. - Collaborate with universities and research institutions to incorporate differentiated applications such as smart wound dressings and wearable sensors into product lines to enhance added value.
