AZO Dye Restrictions Explained: How It Works in Performance Sportswear
AZO Dye Restrictions is best understood as ban on cleavable aromatic amines. This entry explains how it behaves inside a finished garment rather than only in the laboratory.
What the term means
ban on cleavable aromatic amines, which is why the value appears on almost every technical data sheet. Working figures for AZO Dye Restrictions normally sit around below 30 ppm per amine in mainstream production. Note EN 14362 determination on the tech pack so nobody tests against an older revision.
Why it matters in practice
failure leads to shipment rejection, so it influences buying decisions more than most buyers expect. Record elastane content alongside AZO Dye Restrictions, because blends shift the measured value. A result outside below 30 ppm per amine usually points to process drift rather than to the fibre itself.
Typical values seen in activewear
below 30 ppm per amine. Ranges vary by construction, so compare like with like. Keeping reference values for AZO Dye Restrictions lets suppliers quote without extra sampling rounds. Ask for conditioning details together with EN 14362 determination, since both affect the reading.
How it is measured
EN 14362 determination is the reference normally quoted on a test report. Working figures for AZO Dye Restrictions normally sit around below 30 ppm per amine in mainstream production. Note EN 14362 determination 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 AZO Dye Restrictions, because blends shift the measured value. A result outside below 30 ppm per amine usually points to process drift rather than to the fibre itself.
