Anti-Static Finish Frequently Asked Questions
Short answers to the questions buyers ask most often about Anti-Static Finish.
What does it mean?
finish lowering surface resistivity. 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.
What value should be specified?
Start from below 1E11 ohms and adjust for the end use of the garment. 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.
How is it tested?
EN 1149 surface resistance. 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.
Why does it change between lots?
Process variables such as finishing temperature and elastane batch cause the normal spread of results. 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.
Can results be compared across suppliers?
Only when the same standard revision and conditioning are used; otherwise measurements are not equivalent. 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.
