Anti-Static Finish Explained: How It Works in Performance Sportswear
Anti-Static Finish is best understood as finish lowering surface resistivity. This entry explains how it behaves inside a finished garment rather than only in the laboratory.
What the term means
finish lowering surface resistivity, which is why the value appears on almost every technical data sheet. Working figures for Anti-Static Finish normally sit around below 1E11 ohms in mainstream production. Note EN 1149 surface resistance on the tech pack so nobody tests against an older revision.
Why it matters in practice
it prevents cling and lint attraction in dry air, so it influences buying decisions more than most buyers expect. Record elastane content alongside Anti-Static Finish, because blends shift the measured value. A result outside below 1E11 ohms usually points to process drift rather than to the fibre itself.
Typical values seen in activewear
below 1E11 ohms. Ranges vary by construction, so compare like with like. Keeping reference values for Anti-Static Finish lets suppliers quote without extra sampling rounds. Ask for conditioning details together with EN 1149 surface resistance, since both affect the reading.
How it is measured
EN 1149 surface resistance is the reference normally quoted on a test report. Working figures for Anti-Static Finish normally sit around below 1E11 ohms in mainstream production. Note EN 1149 surface resistance 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 Anti-Static Finish, because blends shift the measured value. A result outside below 1E11 ohms usually points to process drift rather than to the fibre itself.
