Wicking Height Frequently Asked Questions
Short answers to the questions buyers ask most often about Wicking Height.
What does it mean?
height liquid rises over a fixed time. Working figures for Wicking Height normally sit around above 100 mm in 30 minutes in mainstream production. Note AATCC 197 vertical wicking on the tech pack so nobody tests against an older revision.
What value should be specified?
Start from above 100 mm in 30 minutes and adjust for the end use of the garment. Record elastane content alongside Wicking Height, because blends shift the measured value. A result outside above 100 mm in 30 minutes usually points to process drift rather than to the fibre itself.
How is it tested?
AATCC 197 vertical wicking. Keeping reference values for Wicking Height lets suppliers quote without extra sampling rounds. Ask for conditioning details together with AATCC 197 vertical wicking, 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 Wicking Height normally sit around above 100 mm in 30 minutes in mainstream production. Note AATCC 197 vertical wicking 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 Wicking Height, because blends shift the measured value. A result outside above 100 mm in 30 minutes usually points to process drift rather than to the fibre itself.
