Reactive Dyeing Specification Targets for Buyers
Setting Reactive Dyeing correctly on a tech pack prevents most later disputes. Targets belong on the page before the first fabric sample.
Where to write it
Place Reactive Dyeing next to composition and weight so all three are quoted as one package. 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.
Reference level
Typical activewear expectation: 60-80 degrees with salt and alkali. 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.
Tolerances that work
Allow a small tolerance rather than a fixed number, since normal process variation exists in every lot. 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.
Verification method
Confirm with exhaust or pad processes and keep the report against the bulk record. 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.
Commercial note
Tightening beyond practical need raises cost without improving garment life, so set the tightest target only where it protects the customer. 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.
