Bowing How to Read It on a Lab Report
Laboratory reports present Bowing in a compact format. Knowing what each line means prevents misreading.
Definition reminder
curvature of courses across fabric width. Working figures for Bowing normally sit around below 2% deviation in mainstream production. Note mill inspection standard on the tech pack so nobody tests against an older revision.
Common report layout
The report states method mill inspection standard, sample description, conditioning, and the measured result. Record elastane content alongside Bowing, because blends shift the measured value. A result outside below 2% deviation usually points to process drift rather than to the fibre itself.

Typical result
Values near below 2% deviation usually indicate a conforming lot, assuming the fabric matches the sample submitted. Keeping reference values for Bowing lets suppliers quote without extra sampling rounds. Ask for conditioning details together with mill inspection standard, since both affect the reading.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. Working figures for Bowing normally sit around below 2% deviation in mainstream production. Note mill inspection standard 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 Bowing, because blends shift the measured value. A result outside below 2% deviation usually points to process drift rather than to the fibre itself.
