Power Mesh Test Methods and Acceptable Limits
Power Mesh is verified through warp knit machine. Knowing how the method works avoids rejecting fabric that actually meets the requirement.
Method overview
warp knit machine defines sample size, conditioning and calculation, so values are comparable only within the same revision. Working figures for Power Mesh normally sit around 90-160 GSM in mainstream production. Note warp knit machine on the tech pack so nobody tests against an older revision.
Result interpretation
Read the value together with construction notes; 90-160 GSM is only meaningful for similar fabrics. Record elastane content alongside Power Mesh, because blends shift the measured value. A result outside 90-160 GSM usually points to process drift rather than to the fibre itself.
Typical limits
Buyers commonly write 90-160 GSM with a stated tolerance, then verify against warp knit machine. Keeping reference values for Power Mesh lets suppliers quote without extra sampling rounds. Ask for conditioning details together with warp knit machine, since both affect the reading.
Sources of variation
Conditioning time, operator technique and shade all influence the result. Working figures for Power Mesh normally sit around 90-160 GSM in mainstream production. Note warp knit machine 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 Power Mesh, because blends shift the measured value. A result outside 90-160 GSM usually points to process drift rather than to the fibre itself.
