PFAS Restrictions Explained: How It Works in Performance Sportswear
PFAS Restrictions is best understood as chemical limits on perfluorinated compounds. This entry explains how it behaves inside a finished garment rather than only in the laboratory.
What the term means
chemical limits on perfluorinated compounds, which is why the value appears on almost every technical data sheet. Working figures for PFAS Restrictions normally sit around moving to non-detect targets in mainstream production. Note EN 17681 tests after degradation on the tech pack so nobody tests against an older revision.
Why it matters in practice
it affects water and stain repellent finishes, so it influences buying decisions more than most buyers expect. Record elastane content alongside PFAS Restrictions, because blends shift the measured value. A result outside moving to non-detect targets usually points to process drift rather than to the fibre itself.
Typical values seen in activewear
moving to non-detect targets. Ranges vary by construction, so compare like with like. Keeping reference values for PFAS Restrictions lets suppliers quote without extra sampling rounds. Ask for conditioning details together with EN 17681 tests after degradation, since both affect the reading.
How it is measured
EN 17681 tests after degradation is the reference normally quoted on a test report. Working figures for PFAS Restrictions normally sit around moving to non-detect targets in mainstream production. Note EN 17681 tests after degradation on the tech pack so nobody tests against an older revision.
Frequent mistakes
Comparing results from different standards, testing unwashed fabric, and writing the target without tolerance are the common errors. Record elastane content alongside PFAS Restrictions, because blends shift the measured value. A result outside moving to non-detect targets usually points to process drift rather than to the fibre itself.
