Tricot Brush Tricot (TBT) Setting It Correctly on a Tech Pack
Tricot Brush Tricot (TBT) should be written into the tech pack with a value, a tolerance and a method. This removes ambiguity from quotations.
Definition to agree
brushed warp knit with soft face and reverse. 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.
Target value
Open the specification at 150-220 GSM, adjusted to the end use. 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.

Method line
Always pair the target with warp knit then raising so the mill and the laboratory test the same way. 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.
Tolerance line
State plus or minus limits to keep production realistic while protecting the requirement. 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.
Approval step
Approve the result on pre-production bulk rather than on development fabric only. 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.
