In the specialty textile sector, a flexible carbon-based fiber named 'Rouhuo' is positioning itself against high-performance aramid at a price of 80,000-90,000 RMB per ton, backed by an eight-year R&D cycle. Developed by Zhejiang Jili New Materials Co., Ltd., this organic-inorganic hybrid carbon fiber intermediate has entered industrial applications in firefighting, new energy, and military sectors, exemplifying a domestic breakthrough in specialty materials.
Industry Context
Traditional carbon fiber is notoriously rigid and difficult to spin into yarn, a core barrier to its use in textiles. Jili's team introduced polymer modification during the spinning stage of carbon fiber precursor, developed proprietary oil agents and sizing agents, and retrofitted spinning equipment to overcome these challenges. The result was significant improvements in strength and abrasion resistance, while eliminating the black debris shedding that plagued the first-generation product. This process breakthrough means carbon-based materials can now extend from structural reinforcements to functional textiles.
At 80,000-90,000 RMB per ton, the fiber is priced higher than conventional synthetics but remains competitive compared to aramid. However, high cost and limited color options are two major constraints for mass consumer adoption. For downstream buyers, this suggests the material is currently better suited for professional markets where performance outweighs price sensitivity.
Application Landscape and Industry Collaboration
Emergency firefighting is the core market for 'Rouhuo'. The material can withstand instantaneous temperatures up to 1,800°C, with zero melting and zero dripping. The company has participated in drafting the industry standard for new energy vehicle fire control blankets led by the China Fire Protection Association, supplied firefighting suit fabrics to Heilongjiang forest fire departments, and developed protective clothing for firefighting robots in collaboration with Xiaoshan Lantian Zhihui. This indicates that while the domestic firefighting market remains policy-driven, leading companies are gaining first-mover advantage by engaging in standard-setting.
In new energy, the material is used in energy storage equipment, EV chassis, seats, and storage motors. In overseas markets, the company exports battery fire-proof bags to Japan, where mandatory standards were introduced after frequent power bank explosion incidents. In contrast, the domestic market has yet to see large-scale adoption, suggesting that mature overseas markets can provide early revenue and validation, while domestic growth depends on the rollout of mandatory regulations.
The material also has potential for high-temperature protective gloves, home curtains, sofas, and hotel carpets, but cost constraints limit civilian applications. In defense, it can be used in specialty protective clothing, chemical suits, and hoods, representing a high-value but barrier-laden segment.
R&D Logic and Future Plans
Jili's R&D path was not linear. The first-generation product 'Carbonron' exposed issues such as insufficient strength, poor abrasion resistance, and debris shedding, forcing the team to redesign from the source process. This iterative R&D approach is common in specialty materials—there is no perfect material, only continuous refinement based on real-world feedback. The company holds a complete technology package, allowing customized modification at the precursor stage for different downstream scenarios, providing technical flexibility for cross-industry penetration.
Notably, the company is actively collaborating with local carbon fiber precursor producers in Shaoxing to strengthen the local supply chain, and uses the 'AI Cloth' mini-program for industry information and resource matching. Digital tools are increasingly important in specialty materials R&D and supply-demand matching, especially for niche segments with long development cycles and dispersed customers.
Currently, the company is applying for the China Textile Industry Federation Science and Technology Progress Award and is in talks with two pre-IPO energy storage companies for financing. Leveraging industrial capital to accelerate technology iteration and expand market channels is a common path for specialty material firms moving from technological leadership to market leadership. In the long run, the team plans to develop other high-temperature resistant specialty textile materials beyond 'Rouhuo', signaling a strategy focused on building a multi-material specialty textile platform rather than a single product.
