Biobased textile auxiliaries accelerate penetration and low-carbon raw materials reshape the green new pattern of the industry
In the context of the global textile industry deeply implementing the dual carbon goals and promoting source reduction of carbon emissions, biobased textile auxiliaries, with their core advantages of renewable raw materials, low emissions, and biodegradability, have become the core breakthrough point for the industry's green transformation. Compared with traditional petroleum-based auxiliaries, biobased auxiliaries use plant oils, starch, and straw extracts as raw materials, significantly reducing their carbon footprint throughout the entire life cycle. They have now been applied throughout the entire process of textile pretreatment, dyeing, and finishing, with a continuously rising market penetration rate, gradually rewriting the industry's raw material supply and product structure pattern.
 
1. Dual-driven by policy and market: The biobased auxiliaries sector expands rapidly
The domestic "14th Five-Year Plan" for the textile industry clearly includes biobased chemicals in the key promotion directory for green manufacturing. Coupled with the strict control of the carbon footprint of textile products by the EU's Carbon Border Adjustment Mechanism (CBAM), the combined efforts of internal and external policies have driven the demand for biobased textile auxiliaries to explode. At the same time, the recognition of consumers for low-carbon textiles continues to increase, and textiles with low-carbon and biobased certifications have a significant market premium, further forcing printing and dyeing enterprises to replace traditional petroleum-based auxiliaries. Industry data shows that the market penetration rate of biobased textile auxiliaries in China has risen from 15% in 2020 to 35% in 2025, with an average annual compound growth rate of over 12%. It is expected that the market size will exceed 8.5 billion yuan in 2027, accounting for nearly 20% of the overall auxiliaries market, becoming the core new engine of industry growth. 

2. Technological breakthroughs address pain points and match performance with traditional petroleum-based products
Early bio-based additives had shortcomings such as poor stability, limited application scenarios, and high costs, making them difficult to be widely applied on a large scale. In recent years, the industry has overcome multiple technical bottlenecks through synthetic biology, biological fermentation technology optimization, and upgrading of polymer compounding processes. The new generation of bio-based pre-treatment additives can complete fiber delaustrification and boiling treatment under low-temperature conditions, achieving the same decontamination effect as traditional additives, with minimal damage to the fibers, and effectively improving the fabric yield. The bio-based dyeing carriers and fixation agents have uniform coloration and color fastness indicators that fully meet the standards, and can be adapted to various fabrics such as pure cotton and recycled cellulose fibers. The bio-based softeners and anti-wrinkle finishing agents give the fabric a soft and skin-friendly feel, and are fully biodegradable, without leaving harmful substances. Currently, the carbon emissions of mainstream bio-based additives are 45%-68% lower than those of petroleum-based products, truly achieving a win-win situation of environmental protection and performance. 

3. Precise Adaptation of Specific Scenarios, Prioritizing In-depth Popularization in High-Sensitivity Fields
Biobased textile auxiliaries, due to their non-toxic, harmless, low-carbon, and environmentally friendly characteristics, have been the first to achieve large-scale application in highly safety-demanding specific scenarios such as infant clothing, medical dressings, and intimate home textiles, with a penetration rate exceeding 50%. In infant textile products, biobased formaldehyde-free color-fixing agents and biobased enzyme softeners have become standard items, completely avoiding the risk of residual harmful substances such as formaldehyde and heavy metals; in the medical textile field, biobased antibacterial finishing agents have both antibacterial effects and biological compatibility, and will not irritate the skin, suitable for surgical gowns, care dressings, etc.; in daily home textiles and underwear fields, biobased moisture-absorbing and breathable auxiliaries enhance the comfort of the fabric while aligning with the current green consumption concept. As costs gradually decline, biobased auxiliaries are rapidly extending to popular scenarios such as sports clothing and workwear fabrics, and the application boundaries are continuously expanding. 

4. Coordinated Upstream-Downstream Upgrade to Promote Low-Carbon Standardization in the Industry
The rapid popularization of bio-based textile auxiliaries has led to a coordinated upgrade of the entire industry chain, including the upstream supply of biomass raw materials, the midstream production and processing, and the downstream application certification. At the upstream raw material end, the technologies for large-scale cultivation and extraction of renewable biomass raw materials have continuously matured, ensuring stable supply and continuously reducing raw material costs; at the midstream production end, enterprises are accelerating the transformation of green production lines, adopting clean production processes, and strictly controlling energy consumption and emissions in the production process; at the downstream application end, the industry is accelerating the establishment of carbon footprint accounting and product certification standards systems for bio-based auxiliaries, promoting the standardization of low-carbon auxiliaries application. In the future, as technology continues to iterate and the industry chain is further improved, bio-based auxiliaries will gradually replace mid-to-low-end petroleum-based auxiliaries, becoming the core support for the green manufacturing and low-carbon export of the textile industry, and helping the entire industry achieve the goal of carbon neutrality.
