Jumping on this thread! Does Cordura fabric contain PFAS? It’s the stuff a lot of tech backpacks are made of!
- mint2 4y agoIf it has a water repellent coating, probably. If it’s part of a gortex thing, yes.
- snowwrestler 4y agoCordura is a brand name for a way of texturing nylon thread. Nylon is not made from PFAS. Cordura often has a coating on the back to make it waterproof, usually polyurethane that is sprayed on—also not PFAS. It may have a DWR treatment on the outside, which makes water bead up and run off. Many DWR treatments are made from, or break down into, PFAS. DWR coatings are far more common on clothes than backpacks, though. You can test by spraying water on the fabric. If it immediately forms round little drops that roll off, like it can’t “touch” the fabric, you’ve got a DWR treatment. If the water sits flat or starts to soak in a bit, you don’t.
