Interlock How to Read It on a Lab Report
Laboratory reports present Interlock in a compact format. Knowing what each line means prevents misreading.
Definition reminder
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.
Common report layout
The report states method interlock machine, sample description, conditioning, and the measured result. 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.
Typical result
Values near 200-280 GSM usually indicate a conforming lot, assuming the fabric matches the sample submitted. 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.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. 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.
Questions to ask
Ask the laboratory for the standard revision and sample description before accepting or rejecting a result. 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.
