Interlock Frequently Asked Questions
Short answers to the questions buyers ask most often about Interlock.
What does it mean?
two single jersey fabrics knitted back to back. Working figures for Interlock normally sit around 200-280 GSM in mainstream production. Note interlock machine on the tech pack so nobody tests against an older revision.
What value should be specified?
Start from 200-280 GSM and adjust for the end use of the garment. Record elastane content alongside Interlock, because blends shift the measured value. A result outside 200-280 GSM usually points to process drift rather than to the fibre itself.
How is it tested?
interlock machine. Keeping reference values for Interlock lets suppliers quote without extra sampling rounds. Ask for conditioning details together with interlock machine, 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 Interlock normally sit around 200-280 GSM in mainstream production. Note interlock machine 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 Interlock, because blends shift the measured value. A result outside 200-280 GSM usually points to process drift rather than to the fibre itself.
