Acid Dyeing How to Read It on a Lab Report
Laboratory reports present Acid Dyeing in a compact format. Knowing what each line means prevents misreading.
Definition reminder
dye class for polyamide. Working figures for Acid Dyeing normally sit around 95-100 degrees with pH control in mainstream production. Note jet dyeing with levelling agents on the tech pack so nobody tests against an older revision.
Common report layout
The report states method jet dyeing with levelling agents, sample description, conditioning, and the measured result. Record elastane content alongside Acid Dyeing, because blends shift the measured value. A result outside 95-100 degrees with pH control usually points to process drift rather than to the fibre itself.
Typical result
Values near 95-100 degrees with pH control usually indicate a conforming lot, assuming the fabric matches the sample submitted. Keeping reference values for Acid Dyeing lets suppliers quote without extra sampling rounds. Ask for conditioning details together with jet dyeing with levelling agents, since both affect the reading.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. Working figures for Acid Dyeing normally sit around 95-100 degrees with pH control in mainstream production. Note jet dyeing with levelling agents 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 Acid Dyeing, because blends shift the measured value. A result outside 95-100 degrees with pH control usually points to process drift rather than to the fibre itself.
