Water Repellency Spray Test Explained: How It Works in Performance Sportswear
Water Repellency Spray Test is best understood as how well water beads on the surface. This entry explains how it behaves inside a finished garment rather than only in the laboratory.
What the term means
how well water beads on the surface, which is why the value appears on almost every technical data sheet. Working figures for Water Repellency Spray Test normally sit around grade 4 to 5 target in mainstream production. Note AATCC 22 spray test on the tech pack so nobody tests against an older revision.
Why it matters in practice
it indicates the finish condition, not waterproofness, so it influences buying decisions more than most buyers expect. Record elastane content alongside Water Repellency Spray Test, because blends shift the measured value. A result outside grade 4 to 5 target usually points to process drift rather than to the fibre itself.
Typical values seen in activewear
grade 4 to 5 target. Ranges vary by construction, so compare like with like. Keeping reference values for Water Repellency Spray Test lets suppliers quote without extra sampling rounds. Ask for conditioning details together with AATCC 22 spray test, since both affect the reading.
How it is measured
AATCC 22 spray test is the reference normally quoted on a test report. Working figures for Water Repellency Spray Test normally sit around grade 4 to 5 target in mainstream production. Note AATCC 22 spray test 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 Water Repellency Spray Test, because blends shift the measured value. A result outside grade 4 to 5 target usually points to process drift rather than to the fibre itself.
