Media: Textile Leader Release Date: June 17, 2026 Interpreter: Wang Jianping, Professor-level Senior Engineer On June 17, 2026, Textile Leader published an in-depth industrial analysis written by Wang Jianping, Professor-level Senior Engineer and Senior Consultant of China United Product Inspection (Beijing) Technology Group. The article systematically reviews the R&D progress of novel fluorine-free water repellents and breaks down five mainstream commercial fluorine-free finishing agents, offering authoritative technical references for the textile industry’s fluorine-free green transformation. With decades of experience in textile chemicals, testing technology, standardization and consumer product safety, Wang Jianping has presided over the formulation of multiple national and industrial standards, published over 130 papers and authored 12 professional monographs. He stated that amid tightening global regulations on PFAS, fluorinated water/oil repellents are facing phased restrictions, making fluorine-free substitution an irreversible industrial trend, yet the sector still faces multiple technical and market barriers. Up to now, no compound has been developed to fully replace fluorinated counterparts, and nearly all fluorine-free products fail to deliver oil repellency. Long-term application of fluorinated chemicals has raised market performance expectations, with key indicators incorporated into industrial standards. The mismatch between the performance limitations of fluorine-free products and market & standard requirements cannot be fully resolved in the short term. Nevertheless, Wang predicted that most civilian textiles only require water repellency without oil-repellent demands, so the market will gradually embrace fluorine-free solutions. The article categorizes five major commercial fluorine-free water repellents and elaborates their working mechanisms, applicable fabrics, merits and drawbacks:

1. Modified Paraffin Water Repellents Optimized based on traditional paraffin to boost environmental friendliness, stability and water repellency. Rarely used alone; usually compounded with acrylic or melamine resin to balance overall performance.
2. Modified Organosilicon Water Repellents Overcome defects of conventional silicones such as emulsion breakage and incompatibility with high-speed chemical fiber processing. Two water-repellent film-forming mechanisms are available:

• PDMS reacts with hydrolysable zirconium/titanium compounds; metal oxides form films on fibers, with crosslinks between Zr/Ti and silicone oxygen to achieve durable water repellency after curing.
• Poly(methylhydrogen siloxane) blends with PDMS or α,ω-dihydroxy PDMS. Under catalyst and high temperature, hydrolysis and condensation build crosslinked silicone networks wrapping fiber surfaces for long-lasting hydrophobicity. Ideal for synthetic fibers and wool textiles.

1. Modified Acrylic Water Repellents Currently the mainstream fluorine-free option thanks to outstanding processability, wash resistance and low cost. Hydrophobicity is enhanced via oriented long alkyl side chains, yet the drawbacks include stiff fabric handfeel and obvious scratch marks. Paraffin or organosilicon is commonly blended to soften touch.

A new-generation bionic multi-link acrylic fluorine-free repellent mimics the structure of water strider legs, featuring highly oriented side chains and high crystallinity for larger water contact angles. It delivers strong water repellency at low dosage, fits high-count high-density fabrics, boasts superior dynamic waterproof performance and stable continuous processing, reduces scratch marks and barely affects fabric shade, with remarkable cost advantages. The journal announced that the second part of the report, R&D Status and Types of New Fluorine-Free Water Repellents (Part II), will be released soon, covering technical details, application challenges and future R&D directions of the remaining two fluorine-free repellent categories. The serial report helps printing & dyeing and fabric manufacturers select eco-friendly auxiliaries accurately and remove bottlenecks in the fluorine-free upgrade of the whole textile supply chain.
