Bonding Frequently Asked Questions
Short answers to the questions buyers ask most often about Bonding.
What does it mean?
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.
What value should be specified?
Start from film thickness 0.05-0.15 mm and adjust for the end use of the garment. 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.

How is it tested?
ISO 15797 dimensional check plus peel test. 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.
Why does it change between lots?
Process variables such as finishing temperature and elastane batch cause the normal spread of results. 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.
Can results be compared across suppliers?
Only when the same standard revision and conditioning are used; otherwise measurements are not equivalent. 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.
