Anti-Static Finish Why Shipments Get Rejected Over This
Many disputes come down to Anti-Static Finish. Below is what inspectors check and why shipments fail.
The core definition
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.
Most common cause of failure
Results usually fall outside below 1E11 ohms because the target was never written into the order. 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 it is checked
Inspection and laboratory work both refer to 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.
Related faults
it prevents cling and lint attraction in dry air, so related complaints often point back to this single parameter. 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.
Avoiding rejection
Agree targets, tolerances and the method before production, then test per lot rather than per shipment. 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.
