Seam Slippage How to Read It on a Lab Report
Laboratory reports present Seam Slippage in a compact format. Knowing what each line means prevents misreading.
Definition reminder
yarn movement away from the seam. Working figures for Seam Slippage normally sit around below 6 mm at 60 N in mainstream production. Note ISO 13936-2 fixed load on the tech pack so nobody tests against an older revision.
Common report layout
The report states method ISO 13936-2 fixed load, sample description, conditioning, and the measured result. Record elastane content alongside Seam Slippage, because blends shift the measured value. A result outside below 6 mm at 60 N usually points to process drift rather than to the fibre itself.
Typical result
Values near below 6 mm at 60 N usually indicate a conforming lot, assuming the fabric matches the sample submitted. Keeping reference values for Seam Slippage lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ISO 13936-2 fixed load, since both affect the reading.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. Working figures for Seam Slippage normally sit around below 6 mm at 60 N in mainstream production. Note ISO 13936-2 fixed load 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 Seam Slippage, because blends shift the measured value. A result outside below 6 mm at 60 N usually points to process drift rather than to the fibre itself.
