Reactive Dyeing How to Read It on a Lab Report
Laboratory reports present Reactive Dyeing in a compact format. Knowing what each line means prevents misreading.
Definition reminder
dye forming a bond with cellulose. Working figures for Reactive Dyeing normally sit around 60-80 degrees with salt and alkali in mainstream production. Note exhaust or pad processes on the tech pack so nobody tests against an older revision.
Common report layout
The report states method exhaust or pad processes, sample description, conditioning, and the measured result. Record elastane content alongside Reactive Dyeing, because blends shift the measured value. A result outside 60-80 degrees with salt and alkali usually points to process drift rather than to the fibre itself.
Typical result
Values near 60-80 degrees with salt and alkali usually indicate a conforming lot, assuming the fabric matches the sample submitted. Keeping reference values for Reactive Dyeing lets suppliers quote without extra sampling rounds. Ask for conditioning details together with exhaust or pad processes, since both affect the reading.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. Working figures for Reactive Dyeing normally sit around 60-80 degrees with salt and alkali in mainstream production. Note exhaust or pad processes 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 Reactive Dyeing, because blends shift the measured value. A result outside 60-80 degrees with salt and alkali usually points to process drift rather than to the fibre itself.
