Bonding Setting It Correctly on a Tech Pack
Bonding should be written into the tech pack with a value, a tolerance and a method. This removes ambiguity from quotations.
Definition to agree
joining two fabrics with adhesive film. Working figures for Bonding normally sit around film thickness 0.05-0.15 mm in mainstream production. Note ISO 15797 dimensional check plus peel test on the tech pack so nobody tests against an older revision.
Target value
Open the specification at film thickness 0.05-0.15 mm, adjusted to the end use. Record elastane content alongside Bonding, because blends shift the measured value. A result outside film thickness 0.05-0.15 mm usually points to process drift rather than to the fibre itself.

Method line
Always pair the target with ISO 15797 dimensional check plus peel test so the mill and the laboratory test the same way. Keeping reference values for Bonding lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ISO 15797 dimensional check plus peel test, since both affect the reading.
Tolerance line
State plus or minus limits to keep production realistic while protecting the requirement. Working figures for Bonding normally sit around film thickness 0.05-0.15 mm in mainstream production. Note ISO 15797 dimensional check plus peel test 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 Bonding, because blends shift the measured value. A result outside film thickness 0.05-0.15 mm usually points to process drift rather than to the fibre itself.
