PFAS in the Textile Industry – Executive Summary for Decision Makers

PFAS in the Textile Industry: Challenges, Outlook & Strategic Recommendations

The glob­al tex­tile industry is under­go­ing a major shift regard­ing the use of per- and poly­fluoroal­kyl sub­stances (PFAS), par­tic­u­larly around dur­able water repel­lents (DWRs). While PFAS have long been val­ued for their excep­tion­al water, oil, and stain repel­lency, increas­ing envir­on­ment­al con­cerns and emer­ging health data have drawn reg­u­lat­ory atten­tion and mar­ket pres­sure world­wide.

Accord­ing to the cur­rent state of sci­ence, there are no flu­or­ine-free altern­at­ives avail­able today that can fully match the per­form­ance characteristics—particularly oil repel­lency and durability—of con­ven­tion­al fluoro­car­bon-based sys­tems. Con­sequently, a suc­cess­ful trans­ition requires a real­ist­ic under­stand­ing of per­form­ance expect­a­tions and a coordin­ated, tier-spe­cif­ic response across the entire value chain.

To sup­port the industry in man­aging this trans­ition, Gherzi recom­mends the fol­low­ing stra­tegic meas­ures:

1. OEMs / Brand Owners

  • Integ­rate FC-free require­ments into RSLs and enforce them con­sist­ently across sup­pli­er onboard­ing, audits, and mater­i­al approvals
  • Estab­lish trace­ab­il­ity mech­an­isms to ensure FC-free com­pli­ance not only in product for­mu­la­tions but through­out man­u­fac­tur­ing envir­on­ments.
  • Mit­ig­ate cross-con­tam­in­a­tion risks by imple­ment­ing clear and robust con­tam­in­a­tion con­trol protocols—accounting for shared equip­ment, water sys­tems, and labor­at­ory tools.

2. Tier 1 Suppliers (Garment Manufacturers & Finishers)

  • Invest in ded­ic­ated fin­ish­ing infra­struc­ture for FC-free treat­ments where eco­nom­ic­ally and logist­ic­ally feas­ible.
  • Enforce strict segreg­a­tion of FC-free and leg­acy fluoro­car­bon-based treatments—across stor­age, chem­ic­al hand­ling, dos­ing, and wastewa­ter man­age­ment.
  • Request full doc­u­ment­a­tion and third-party val­id­a­tion from chem­ic­al sup­pli­ers to sup­port claims of FC-free product per­form­ance.

3. Tier 3 Suppliers (Chemical Manufacturers)

  • Pri­or­it­ize the devel­op­ment and scale-up of FC-free DWR for­mu­la­tions with full chem­ic­al trans­par­ency and align­ment with upcom­ing glob­al reg­u­lat­ory frame­works (e.g., EU PFAS restric­tions).
  • Chan­nel innov­a­tion into high-per­form­ance solu­tions with­in the real­ist­ic bound­ar­ies of FC-free chem­istry, with clear com­mu­nic­a­tion of lim­it­a­tions.
  • Col­lab­or­ate closely with brands and mills to test and val­id­ate optim­al applic­a­tions for FC-free sys­tems based on spe­cif­ic use cases and per­form­ance demands.

Understanding Detection Limits in PFAS Analytics

In the con­text of PFAS test­ing, a sound under­stand­ing of ana­lyt­ic­al detec­tion lim­its is essen­tial for accur­ate com­pli­ance, cred­ible declar­a­tions, and sound decision-mak­ing.

  • Lim­it of Detec­tion (LOD): The low­est con­cen­tra­tion at which a sub­stance can be reli­ably iden­ti­fied.
  • Lim­it of Quan­ti­fic­a­tion (LOQ): The low­est level at which the con­cen­tra­tion can be meas­ured with accept­able pre­ci­sion.

Typical Detection Limits in Textile Testing:

  • Fin­ished tex­tiles: 0.1–1 µg/m² (per com­pound)
  • Water samples (efflu­ent, pro­cess water): 1–10 ng/l (parts per tril­lion)

While these ultra-trace levels are cru­cial for safe­guard­ing health and the envir­on­ment, they intro­duce inter­pret­a­tion­al com­plex­ity.

Key Considerations for the Industry

  1. “Non-detect” does not mean “absent”

PFAS may be present below the detec­tion threshold. There­fore, any “PFAS-free” claim should be sup­por­ted by test details includ­ing LOD and LOQ.

  1. Cross-con­tam­in­a­tion is a fre­quent and under­es­tim­ated risk

Sources include pre­vi­ously used equip­ment, shared chem­ic­al baths, poorly cleaned con­tain­ers, and even lab back­ground inter­fer­ence.

  1. Labor­at­ory cred­ib­il­ity is essen­tial

Work exclus­ively with accred­ited labs using val­id­ated PFAS test meth­ods (e.g., LC- MS/MS), and ensure test res­ults clearly report detec­tion thresholds.

Communicating “PFAS-Free” Status – Accuracy and Accountability

Mod­ern PFAS ana­lyt­ics enable unpre­ced­en­ted detec­tion sens­it­iv­ity, yet this brings added respons­ib­il­ity in com­mu­nic­a­tion. To cred­ibly claim “PFAS-free” status, organ­iz­a­tions must ensure:

  • Full sup­ply chain con­trol
  • Pro­act­ive con­tam­in­a­tion pre­ven­tion
  • Con­tinu­ous train­ing and val­id­a­tion across all tiers

Conclusion: The PFAS Transition Is a Necessity—and an Opportunity

Mov­ing away from flu­or­in­ated DWRs is not only a reg­u­lat­ory require­ment but also a chance to lead on sus­tain­ab­il­ity and innov­a­tion. Stake­hold­ers must align on prac­tic­al per­form­ance expect­a­tions, main­tain oper­a­tion­al dis­cip­line, and embrace shared account­ab­il­ity across the sup­ply chain.

Background: History, Use, and Regulation of PFAS

Per- and poly­fluoroal­kyl sub­stances (PFAS) were first developed in the late 1930s and entered com­mer­cial use in the 1940s, ini­tially through products like Teflon™ by DuPont (intro­duced 1946). Due to their unique properties—extreme chem­ic­al sta­bil­ity, water and oil repel­lency, and res­ist­ance to heat—PFAS quickly found wide­spread use across mul­tiple indus­tries. These include tex­tiles (for dur­able water repel­lency), fire­fight­ing foams (AFFF), food pack­aging, cos­met­ics, and elec­tron­ics.

Con­cerns over PFAS began to emerge in the late 1990s when intern­al stud­ies and envir­on­ment­al find­ings revealed their per­sist­ence and poten­tial tox­icity. PFAS have been found in drink­ing water, soil, wild­life, and even human blood around the world.

Key Milestones in PFAS-Awareness and Regulation:

  • 1998 – U.S. Envir­on­ment­al Pro­tec­tion Agency (EPA) begins invest­ig­at­ing PFOS (per­fluo­rooctane sulf­on­ate) after 3M sub­mits intern­al stud­ies.
  • 2001 – The Ten­nessean and oth­er U.S. media expose DuPont’s intern­al know­ledge of PFAS con­tam­in­a­tion, trig­ger­ing law­suits.
  • 2005 – EPA files suit against DuPont for fail­ing to report PFAS risks (settled for $16.5 mil­lion).
  • 2006 – EPA launches the PFOA Stew­ard­ship Pro­gram with major man­u­fac­tur­ers to phase out PFOA by 2015.
  • 2016 – EPA sets a non-enforce­able Health Advis­ory Level for PFOA and PFOS in drink­ing water (70 ppt).
  • 2019 – The European Chem­ic­als Agency (ECHA) clas­si­fies PFAS as sub­stances of very high con­cern (SVHC).
  • 2020 – The film Dark Waters (based on real events, star­ring Mark Ruf­falo) dra­mat­ic­ally increases pub­lic aware­ness of PFAS and their dangers.
  • 2021 – The EU announces inten­tion to restrict the entire PFAS group under REACH by 2025.
  • 2023 – Ger­many, the Neth­er­lands, Den­mark, Sweden, and Nor­way sub­mit a joint restric­tion pro­pos­al to ECHA to ban over 10,000 PFAS sub­stances.
  • 2024 – The U.S. EPA final­izes enforce­able drink­ing water lim­its for six PFAS com­pounds, mark­ing a reg­u­lat­ory turn­ing point.

Key Publications and Media Contributions:

  • 2007 – “Expos­ure” by Robert Bilott: Leg­al exposé of PFAS pol­lu­tion cases against DuPont.
  • 2016 – The Dev­il We Know (Doc­u­ment­ary): Chron­icles the com­munity affected by PFAS pol­lu­tion in West Vir­gin­ia.
  • 2019 – Dark Waters (Film): A dram­at­ized account of attor­ney Robert Bilot­t’s two- dec­ade leg­al battle over PFAS.
  • 2020s – Ongo­ing aca­dem­ic research: Hun­dreds of peer-reviewed stud­ies now link PFAS to can­cer, hor­mone dis­rup­tion, devel­op­ment­al issues, and immune sys­tem effects.
