Raschel Knit Setting It Correctly on a Tech Pack
Raschel Knit should be written into the tech pack with a value, a tolerance and a method. This removes ambiguity from quotations.
Definition to agree
warp knit capable of open mesh structures. 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.
Target value
Open the specification at 60-300 GSM, adjusted to the end use. 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.

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