Thread by Thread: PFAS Throughout the Global Textile Industry
The global textile industry—producing over 100 billion garments annually for a global market—is among the largest industrial users of PFAS compounds. From performance athletic wear to work uniforms, from automotive seat covers to home furnishing textiles, PFAS are used throughout the textile supply chain for their water resistance, stain repellency, and durability properties. The supply chain complexity that characterizes global textile production—with fiber producers, spinners, weavers, dyers, finishers, garment manufacturers, and retailers distributed across dozens of countries—makes PFAS traceability and elimination an enormously complex challenge that the industry is only beginning to systematically address.
PFAS Use Points in Textile Production
PFAS enter textile supply chains at multiple production steps. Fiber production—particularly fluoropolymer fiber manufacturing for technical textiles and membrane applications—uses PFAS both as processing aids and as the fiber polymer itself. Textile dyeing and finishing operations use PFAS-based surfactants as leveling agents, penetrants, and wetting agents that improve dye uptake and distribution uniformity. Performance treatment application—the most visible PFAS use in textiles—involves applying DWR fluorochemical coatings to finished fabric as a final step before garment assembly.
Waterproofing membrane production—particularly expanded PTFE (ePTFE) membranes used in Gore-Tex and similar laminate fabrics—involves PFAS as the primary membrane material. While ePTFE polymers are considered lower-risk than mobile PFAS molecules due to their high molecular weight, the manufacturing process for ePTFE uses PFAS processing aids including PFOA (historically) and GenX replacements that may be present as residual manufacturing contaminants in the finished product and are discharged in manufacturing wastewater.
Supply Chain Transparency Challenges
Textile supply chain PFAS transparency faces fundamental structural barriers. Most major brands do not directly manufacture their garments; they contract with multiple-tier supplier networks extending across multiple countries. Tier 1 suppliers (garment factories) may know what chemical treatments are applied at their facilities; Tier 2 (fabric mills) may have information about fabric treatments; but Tier 3 and beyond (chemical suppliers, fiber producers) typically do not disclose chemical ingredient information to downstream brand customers. This opacity means that brands cannot readily certify PFAS content in their products without conducting their own comprehensive ingredient mapping and testing programs.
Zara parent Inditex, H&M Group, Nike, and Adidas have all published PFAS phase-out commitments and supplier requirements, but execution varies. Supplier auditing programs that verify PFAS compliance—including on-site chemical reviews, wastewater testing, and product testing by accredited laboratories—are essential for backing up brand-level commitments with supply chain reality. The most credible programs test finished garments for PFAS rather than relying solely on chemical management declarations from suppliers—a higher bar that distinguishes genuine PFAS elimination programs from marketing claims.
PFAS Textile Contamination from Manufacturing Discharge
Textile dyeing and finishing operations—concentrated in manufacturing hubs in Bangladesh, India, China, Vietnam, and Turkey—discharge PFAS-containing wastewater to rivers and municipal treatment systems that are poorly equipped to remove PFAS. River contamination studies near textile manufacturing clusters in the Yangtze River delta, Ganges tributaries near Tirupur (India’s textile hub), and Buriganga River near Dhaka have detected PFAS at concentrations reflecting manufacturing discharges. For populations relying on these rivers for drinking water and irrigation, textile PFAS manufacturing represents a direct source of human PFAS exposure in countries where regulatory frameworks for emerging contaminants are still developing.
