Raschel Knit Test Methods and Acceptable Limits
Raschel Knit is verified through raschel machines. Knowing how the method works avoids rejecting fabric that actually meets the requirement.
Method overview
raschel machines defines sample size, conditioning and calculation, so values are comparable only within the same revision. Working figures for Raschel Knit normally sit around 60-300 GSM in mainstream production. Note raschel machines on the tech pack so nobody tests against an older revision.
Result interpretation
Read the value together with construction notes; 60-300 GSM is only meaningful for similar fabrics. Record elastane content alongside Raschel Knit, because blends shift the measured value. A result outside 60-300 GSM usually points to process drift rather than to the fibre itself.
Typical limits
Buyers commonly write 60-300 GSM with a stated tolerance, then verify against raschel machines. Keeping reference values for Raschel Knit lets suppliers quote without extra sampling rounds. Ask for conditioning details together with raschel machines, since both affect the reading.
Sources of variation
Conditioning time, operator technique and shade all influence the result. Working figures for Raschel Knit normally sit around 60-300 GSM in mainstream production. Note raschel machines 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 Raschel Knit, because blends shift the measured value. A result outside 60-300 GSM usually points to process drift rather than to the fibre itself.
