Fleece Brush Back Setting It Correctly on a Tech Pack
Fleece Brush Back should be written into the tech pack with a value, a tolerance and a method. This removes ambiguity from quotations.
Definition to agree
knit whose reverse side has been raised. Working figures for Fleece Brush Back normally sit around 260-340 GSM in mainstream production. Note raising machine on the tech pack so nobody tests against an older revision.
Target value
Open the specification at 260-340 GSM, adjusted to the end use. Record elastane content alongside Fleece Brush Back, because blends shift the measured value. A result outside 260-340 GSM usually points to process drift rather than to the fibre itself.
Method line
Always pair the target with raising machine so the mill and the laboratory test the same way. Keeping reference values for Fleece Brush Back lets suppliers quote without extra sampling rounds. Ask for conditioning details together with raising machine, since both affect the reading.
Tolerance line
State plus or minus limits to keep production realistic while protecting the requirement. Working figures for Fleece Brush Back normally sit around 260-340 GSM in mainstream production. Note raising machine 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 Fleece Brush Back, because blends shift the measured value. A result outside 260-340 GSM usually points to process drift rather than to the fibre itself.
