Tricot Brush Tricot (TBT) How It Changes with Construction and Elastane Content
Tricot Brush Tricot (TBT) does not stay constant when construction changes. Understanding the direction of change helps during development.
Effect of knit structure
Loop length and density move results first, usually before any yarn change is made. 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.
Effect of elastane content
More elastane raises recovery but changes the value measured by warp knit then raising, so retest after any blending change. 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.

Effect of finishing
Heat setting and softeners shift results, which explains differences between a hand sample and bulk. 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.
Typical range
Working values stay around 150-220 GSM for mainstream activewear. 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.
Development advice
Change one variable at a time, then verify against warp knit then raising before moving to the next sample round. 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.
