Pad-Batch Dyeing Frequently Asked Questions
Short answers to the questions buyers ask most often about Pad-Batch Dyeing.
What does it mean?
padding dye liquor then cold dwell. Working figures for Pad-Batch Dyeing normally sit around for reactive dyes on cellulose in mainstream production. Note padder plus rotating batch on the tech pack so nobody tests against an older revision.
What value should be specified?
Start from for reactive dyes on cellulose and adjust for the end use of the garment. Record elastane content alongside Pad-Batch Dyeing, because blends shift the measured value. A result outside for reactive dyes on cellulose usually points to process drift rather than to the fibre itself.
How is it tested?
padder plus rotating batch. Keeping reference values for Pad-Batch Dyeing lets suppliers quote without extra sampling rounds. Ask for conditioning details together with padder plus rotating batch, since both affect the reading.
Why does it change between lots?
Process variables such as finishing temperature and elastane batch cause the normal spread of results. Working figures for Pad-Batch Dyeing normally sit around for reactive dyes on cellulose in mainstream production. Note padder plus rotating batch on the tech pack so nobody tests against an older revision.
Can results be compared across suppliers?
Only when the same standard revision and conditioning are used; otherwise measurements are not equivalent. Record elastane content alongside Pad-Batch Dyeing, because blends shift the measured value. A result outside for reactive dyes on cellulose usually points to process drift rather than to the fibre itself.
