Exhaust Dyeing Explained: How It Works in Performance Sportswear
Exhaust Dyeing is best understood as dye transferred from bath to fabric in batch. This entry explains how it behaves inside a finished garment rather than only in the laboratory.
What the term means
dye transferred from bath to fabric in batch, which is why the value appears on almost every technical data sheet. Working figures for Exhaust Dyeing normally sit around liquor ratio 1:8 to 1:15 in mainstream production. Note jet or overflow machines on the tech pack so nobody tests against an older revision.
Why it matters in practice
it suits small and medium orders, so it influences buying decisions more than most buyers expect. Record elastane content alongside Exhaust Dyeing, because blends shift the measured value. A result outside liquor ratio 1:8 to 1:15 usually points to process drift rather than to the fibre itself.
Typical values seen in activewear
liquor ratio 1:8 to 1:15. Ranges vary by construction, so compare like with like. Keeping reference values for Exhaust Dyeing lets suppliers quote without extra sampling rounds. Ask for conditioning details together with jet or overflow machines, since both affect the reading.
How it is measured
jet or overflow machines is the reference normally quoted on a test report. Working figures for Exhaust Dyeing normally sit around liquor ratio 1:8 to 1:15 in mainstream production. Note jet or overflow machines 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 Exhaust Dyeing, because blends shift the measured value. A result outside liquor ratio 1:8 to 1:15 usually points to process drift rather than to the fibre itself.
