Drying Rate Explained: How It Works in Performance Sportswear
Drying Rate is best understood as time for wet fabric to reach equilibrium. This entry explains how it behaves inside a finished garment rather than only in the laboratory.
What the term means
time for wet fabric to reach equilibrium, which is why the value appears on almost every technical data sheet. Working figures for Drying Rate normally sit around under 30 minutes for lightweight knits in mainstream production. Note AATCC 199 drying rate on the tech pack so nobody tests against an older revision.
Why it matters in practice
slow drying makes garments cold after training, so it influences buying decisions more than most buyers expect. Record elastane content alongside Drying Rate, because blends shift the measured value. A result outside under 30 minutes for lightweight knits usually points to process drift rather than to the fibre itself.
Typical values seen in activewear
under 30 minutes for lightweight knits. Ranges vary by construction, so compare like with like. Keeping reference values for Drying Rate lets suppliers quote without extra sampling rounds. Ask for conditioning details together with AATCC 199 drying rate, since both affect the reading.
How it is measured
AATCC 199 drying rate is the reference normally quoted on a test report. Working figures for Drying Rate normally sit around under 30 minutes for lightweight knits in mainstream production. Note AATCC 199 drying rate 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 Drying Rate, because blends shift the measured value. A result outside under 30 minutes for lightweight knits usually points to process drift rather than to the fibre itself.
