Plating Test Methods and Acceptable Limits
Plating is verified through plating technique. Knowing how the method works avoids rejecting fabric that actually meets the requirement.
Method overview
plating technique defines sample size, conditioning and calculation, so values are comparable only within the same revision. Working figures for Plating normally sit around face and back yarns differ in mainstream production. Note plating technique on the tech pack so nobody tests against an older revision.
Result interpretation
Read the value together with construction notes; face and back yarns differ is only meaningful for similar fabrics. Record elastane content alongside Plating, because blends shift the measured value. A result outside face and back yarns differ usually points to process drift rather than to the fibre itself.
Typical limits
Buyers commonly write face and back yarns differ with a stated tolerance, then verify against plating technique. Keeping reference values for Plating lets suppliers quote without extra sampling rounds. Ask for conditioning details together with plating technique, since both affect the reading.
Sources of variation
Conditioning time, operator technique and shade all influence the result. Working figures for Plating normally sit around face and back yarns differ in mainstream production. Note plating technique on the tech pack so nobody tests against an older revision.
Documentation
Record the standard revision on every report, because older versions can differ from current practice. Record elastane content alongside Plating, because blends shift the measured value. A result outside face and back yarns differ usually points to process drift rather than to the fibre itself.
