PFAS Functions in Textile Applications
PFAS — primarily fluoropolymer-based durable water repellent (DWR) finishes — are used extensively in outdoor apparel, sportswear, workwear, and military gear to provide water and stain resistance. PFAS-based DWR finishes provide superior water bead-off performance compared to non-fluorinated alternatives, making them the industry standard for high-performance outdoor gear.
Beyond DWR finishes, PFAS are used in textile production as processing aids, release agents in fabric finishing, and as components of specialty performance fabrics. The textile industry is among the top five PFAS-using sectors in Europe, and apparel ranks among the highest-volume consumer product categories containing PFAS.
EU Regulatory Pressure on Textile PFAS
REACH restrictions have progressively targeted PFAS in textiles. PFOS has been restricted in textiles since 2008. PFOA restrictions took effect in 2020, forcing reformulation of DWR finishes. The proposed universal PFAS restriction under REACH would eliminate essentially all PFAS from textile applications, including the C6 and C4 fluorochemicals that replaced PFOA and PFOS.
The EU’s Sustainable and Circular Textiles Strategy calls for all textile products sold in the EU to be free from hazardous substances — explicitly referencing PFAS — by 2030. The combination of REACH restrictions and broader textile sustainability requirements is creating a clear regulatory direction that PFAS must be eliminated from EU-market textiles.
Industry Response and Non-Fluorinated Alternatives
Major outdoor apparel brands including Patagonia, Arc’teryx, The North Face, and Gore-Tex parent company W.L. Gore have announced transitions to PFAS-free DWR finishes and are at various stages of reformulating their product lines. Non-fluorinated DWR technologies — based on polyurethane, silicone, and wax chemistries — have improved significantly and now meet performance requirements for most applications.
The transition is more challenging for products requiring extreme water resistance in demanding conditions — certain military gear, rescue equipment, and professional outdoor workwear. These applications are driving continued R&D investment in high-performance non-fluorinated alternatives that can match PFAS performance across the full range of temperature, pressure, and mechanical stress conditions.
