Spacer Fabric Setting It Correctly on a Tech Pack
Spacer Fabric should be written into the tech pack with a value, a tolerance and a method. This removes ambiguity from quotations.
Definition to agree
two faces joined by spacer yarns. Working figures for Spacer Fabric normally sit around 250-450 GSM in mainstream production. Note double Raschel machines on the tech pack so nobody tests against an older revision.
Target value
Open the specification at 250-450 GSM, adjusted to the end use. Record elastane content alongside Spacer Fabric, because blends shift the measured value. A result outside 250-450 GSM usually points to process drift rather than to the fibre itself.

Method line
Always pair the target with double Raschel machines so the mill and the laboratory test the same way. Keeping reference values for Spacer Fabric lets suppliers quote without extra sampling rounds. Ask for conditioning details together with double 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 Spacer Fabric normally sit around 250-450 GSM in mainstream production. Note double 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 Spacer Fabric, because blends shift the measured value. A result outside 250-450 GSM usually points to process drift rather than to the fibre itself.
