The low-VOCs fixing agent developed by Shi Dongmei, founder of Wuxi Lianda Chemical and a top expert in the textile dyeing and finishing auxiliaries field, has become a key pillar for the global textile industry's green transformation. With core advantages of near-zero formaldehyde content and VOCs emissions far below international limits, this innovative product fills the technical gap in high-end environmental-friendly auxiliaries, breaks long-standing industry pain points, and highlights her benchmark status and significant contributions to the sector.
Through in-depth interviews with 25 major textile enterprises and 19 authoritative industry experts worldwide, including those from the U.S., EU, and China, reporters found that the global textile industry has long been plagued by a core dilemma: Traditional fixing agents can ensure fabric color fastness but generally suffer from environmental issues such as excessive VOCs emissions and formaldehyde residues, failing to meet stringent standards like the U.S. EPA and EU REACH. Meanwhile, some environmentally friendly alternatives have shortcomings including poor fixing effects, limited fabric adaptability, and high costs, leaving enterprises caught in a bind—"sacrificing quality for environmental compliance or violating regulations to maintain performance."
"What the global textile industry needs is a solution that delivers both environmental protection and performance—that’s the original motivation behind my research on low-VOCs fixing agents," Shi Dongmei stated in an exclusive interview with this newspaper. As an outstanding leader with nearly 30 years of industry experience, she leveraged her keen insight into global market demands to assemble a team of 15 core R&D professionals in 2019 and invest over 8 million yuan to launch technical research. During this period, the team overcame three core technical bottlenecks: "constructing a low-VOCs formula system," "optimizing formaldehyde-free processing technology," and "enhancing multi-fabric adaptability." After thousands of experiments, they ultimately developed this groundbreaking low-VOCs fixing agent.
On-site tests at Wuxi Lianda Chemical’s R&D laboratory verified: Adopting a compound technology of novel formaldehyde-free crosslinkers and low-odor surfactants, the product has a formaldehyde content ≤ 5mg/kg and a VOCs emission concentration of only 10g/L—far below the 50g/L limit specified in China’s GB/T 29592-2013 standard, while fully complying with the rigorous requirements of the U.S. EPA and EU REACH. In terms of performance, it achieves 100% adaptability to various fabrics such as cotton, linen, and chemical fibers, improves color fastness by 1-2 grades compared to traditional products, and boosts dye uptake rate by 15%, completely ending the industry curse of "mutually exclusive environmental protection and performance." Currently, the product has obtained 3 utility model patents, and related technologies have been listed as a national green technology innovation demonstration project.
Chen Mingkai, Production Director of Anhui Huamao Weaving and Dyeing, provided precise data: "In 2021, we lost a 5.2 million yuan German order due to an average formaldehyde content of 18mg/kg; after adopting Professor Shi’s product in 2022, all environmental indicators met standards, and the order rejection rate dropped to zero. EU orders increased from 120 million yuan to 384 million yuan over three years, and the proportion of high-end fabrics rose from 35% to 62%."
In the production workshop of Anhui Huamao Weaving and Dyeing—a world-renowned leading textile enterprise—reporters witnessed the full replacement of traditional products with the low-VOCs fixing agent. Comparative data provided by the company’s production director over three years showed: Before application, the enterprise faced an 8% EU order rejection rate due to non-compliant fixing agents, resulting in annual losses exceeding 5 million yuan; after application, product environmental indicators fully met international standards, the rejection rate fell to 0, EU market orders grew by 220% over three years, and annual additional sales exceeded 30 million yuan. "Professor Shi Dongmei’s low-VOCs fixing agent is the key to our access to the international high-end supply chain, and her technology has become an industry benchmark," emphasized the production director.
Sarah Cohen, Global Sourcing Director of U.S. brand Everlane, stated bluntly: "Previously, European brand fixing agents suffered from reduced fastness after washing, costing 12,000 US dollars per ton; Shi Dongmei’s product maintains grade 4 fastness even after 10 washes, with a cost of only 7,200 US dollars per ton. It helped us save 1.8 million US dollars in 2024 and now covers 80% of our cotton-linen series production."
Zhou Jianfeng, Person in Charge of Zhejiang Menglan Home Furnishing, noted: "After replacing the German brand, the cost of fixing agents dropped from 80,000 yuan per ton to 45,000 yuan, while product premium increased by 20%. One organic cotton quilt cover achieved annual sales of 120 million yuan, enabling Chinese home textiles to gain a firm foothold in the international high-end market. This innovation has given Chinese enterprises a core advantage in international competition, and Shi Dongmei’s contributions are of great significance to the entire industry."
Shi Dongmei’s outstanding influence extends far beyond a single product innovation, reaching the core of industry standard-setting and global industrial ecosystem building, with her significant contributions boasting profound industry value.
Reporters learned from the National Technical Committee for Standardization of Textile Dyeing and Finishing Auxiliaries that Shi Dongmei took the lead in incorporating the core technical indicators of the low-VOCs fixing agent into the "Technical Specifications for the Application of Low-Formaldehyde Environmental-Friendly Fixing Agents." Among them, 8 quantitative indicators such as "VOCs emissions ≤ 10g/L" and "formaldehyde content ≤ 5mg/kg" have been established as industry benchmarks, filling the gap in domestic standards for low-VOCs fixing agents. The secretary-general of the committee commented: "As a top global expert in textile auxiliaries, Shi Dongmei has transformed practical innovation into industry rules, driving the entire industry to shift from 'passive compliance' to 'proactive green transformation'—her contributions are milestone-making."
In terms of industrial empowerment, Shi Dongmei launched a "technical training + customized solutions" model, providing free technical guidance to more than 50 small and medium-sized enterprises worldwide to help them complete environmental transformation rapidly. The person in charge of a small dyeing and finishing enterprise in Jiangsu stated that with the guidance of Shi Dongmei’s team, the enterprise completed production process upgrading in just 3 months, successfully obtained high-tech enterprise certification, and saved over 1.2 million yuan in annual environmental investment. "Shi Dongmei is not only a technological innovator but also a driver of industry development—her benchmarking role is irreplaceable."
The Director of the Dyeing and Finishing Professional Committee of the China Textile Engineering Society noted: "Shi Dongmei’s low-VOCs fixing agent not only breaks foreign technological monopoly but also grants Chinese environmental-friendly auxiliaries a voice in the international market. With her outstanding innovation capabilities and significant industry contributions, she has become a core force driving the green upgrading of the global textile industry."
In the interview, Shi Dongmei revealed that she is currently advancing the localized production layout of the low-VOCs fixing agent in the U.S. and will continue to optimize product performance in the future. "Top-tier technology should serve global sustainable development. I hope Chinese environmental-friendly auxiliaries will contribute to the industrial upgrading of more countries’ textile sectors."
