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