Scouring How to Read It on a Lab Report
Laboratory reports present Scouring in a compact format. Knowing what each line means prevents misreading.
Definition reminder
removal of oils and processing residues. Working figures for Scouring normally sit around before bleaching or dyeing in mainstream production. Note alkaline scouring process on the tech pack so nobody tests against an older revision.
Common report layout
The report states method alkaline scouring process, sample description, conditioning, and the measured result. Record elastane content alongside Scouring, because blends shift the measured value. A result outside before bleaching or dyeing usually points to process drift rather than to the fibre itself.
Typical result
Values near before bleaching or dyeing usually indicate a conforming lot, assuming the fabric matches the sample submitted. Keeping reference values for Scouring lets suppliers quote without extra sampling rounds. Ask for conditioning details together with alkaline scouring process, since both affect the reading.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. Working figures for Scouring normally sit around before bleaching or dyeing in mainstream production. Note alkaline scouring process 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 Scouring, because blends shift the measured value. A result outside before bleaching or dyeing usually points to process drift rather than to the fibre itself.
