Tricot Brush Tricot (TBT) Test Methods and Acceptable Limits
Tricot Brush Tricot (TBT) is verified through warp knit then raising. Knowing how the method works avoids rejecting fabric that actually meets the requirement.
Method overview
warp knit then raising defines sample size, conditioning and calculation, so values are comparable only within the same revision. Working figures for Tricot Brush Tricot (TBT) normally sit around 150-220 GSM in mainstream production. Note warp knit then raising on the tech pack so nobody tests against an older revision.
Result interpretation
Read the value together with construction notes; 150-220 GSM is only meaningful for similar fabrics. Record elastane content alongside Tricot Brush Tricot (TBT), because blends shift the measured value. A result outside 150-220 GSM usually points to process drift rather than to the fibre itself.
Typical limits
Buyers commonly write 150-220 GSM with a stated tolerance, then verify against warp knit then raising. Keeping reference values for Tricot Brush Tricot (TBT) lets suppliers quote without extra sampling rounds. Ask for conditioning details together with warp knit then raising, since both affect the reading.
Sources of variation
Conditioning time, operator technique and shade all influence the result. Working figures for Tricot Brush Tricot (TBT) normally sit around 150-220 GSM in mainstream production. Note warp knit then raising 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 Tricot Brush Tricot (TBT), because blends shift the measured value. A result outside 150-220 GSM usually points to process drift rather than to the fibre itself.
