On December 5, 2025, Shaoxing - Against the backdrop of increasingly strict environmental regulations, the demand for fluorine free waterproofing agents in the textile industry continues to rise. Shaoxing Yuanyuan Textile Technology Co., Ltd. has successfully broken the environmental dilemma of traditional fluorine based waterproofing agents with its independently developed silicone oil-based fluorine free waterproofing agent, providing high-performance and sustainable solutions for outdoor clothing, home textiles and other fields.


Technological breakthrough: Silicone oil modification achieves a balance between waterproofing and environmental protection
Traditional fluorine based waterproofing agents are being restricted from use in many countries worldwide due to the presence of harmful substances such as PFOS/PFOA. However, although fluorine free waterproofing agents on the market are environmentally friendly, they generally have problems such as poor washing resistance and hard hand feel. Shaoxing Traceability team developed a new silicone modified polyacrylate waterproof agent by lotion polymerization of hydrogen containing silicone oil and acrylate monomer through molecular structure design. This technology forms a dense waterproof film on the surface of fabrics through the hydrophobic crystallization characteristics of siloxane segments, while retaining the breathability and softness of the fibers.


Experimental data shows that the polyester taffeta fabric treated with this waterproofing agent has a waterproof grade of 5 in the AATCC 22 standard test (no wet marks after spraying), maintains a waterproof performance of over 80 points after 10 washes, and has a total color difference Δ E<1, almost no color change. In addition, the phenomenon of white marks on the hand is reduced by 60% compared to commercially available fluorine free products, and the hand feel is closer to fluorine based products, solving the technical pain point of fluorine free waterproofing agents for a long time.


Market application: Comprehensive penetration from outdoor equipment to high-end home textiles
At present, this technology has been applied to multiple well-known brands. After adopting traceability waterproofing agents, a certain outdoor clothing enterprise in Ningbo significantly outperformed its competitors in terms of washability and drying speed, with a 30% year-on-year increase in order volume; A silk factory in Hangzhou has achieved an ISO 105-X12 standard waterproof rating while retaining the luster of silk by customizing a low modulus silicone waterproofing agent. The customer complaint rate for high-end bedding series exported to Europe has decreased by 80%.


The core advantage of silicone oil based fluorine free waterproofing agents lies in their compatibility between environmental friendliness and functionality, "said the technical director of Shaoxing Traceability." By adjusting the length and crosslinking density of silicone oil molecular chains, we can accurately match the needs of different fabrics such as cotton, linen, and synthetic fibers, and even achieve multifunctional integration such as waterproofing, oil resistance, and antibacterial properties


Industry Impact: Promoting Green Transformation of Textile Supply Chain
According to QYResearch's prediction, the global market size of hydrogen containing silicone oil will reach 5.02 billion yuan by 2031, with the textile sector accounting for over 42%. The breakthrough in tracing the origin of Shaoxing not only opens up new paths for the application of silicone oil, but also helps Chinese textile enterprises break through trade barriers such as EU REACH regulations. At present, the company has established joint laboratories with universities such as Donghua University and Zhejiang University of Technology to continuously optimize silicone oil modification technology, with the goal of achieving a full range of products without fluorination by 2026.
