Solution Dyeing Frequently Asked Questions
Short answers to the questions buyers ask most often about Solution Dyeing.
What does it mean?
adding pigment before filament extrusion. Working figures for Solution Dyeing normally sit around highest light and chlorine fastness in mainstream production. Note polymer and spinneret process on the tech pack so nobody tests against an older revision.
What value should be specified?
Start from highest light and chlorine fastness and adjust for the end use of the garment. Record elastane content alongside Solution Dyeing, because blends shift the measured value. A result outside highest light and chlorine fastness usually points to process drift rather than to the fibre itself.
How is it tested?
polymer and spinneret process. Keeping reference values for Solution Dyeing lets suppliers quote without extra sampling rounds. Ask for conditioning details together with polymer and spinneret process, 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 Solution Dyeing normally sit around highest light and chlorine fastness in mainstream production. Note polymer and spinneret process 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 Solution Dyeing, because blends shift the measured value. A result outside highest light and chlorine fastness usually points to process drift rather than to the fibre itself.
