Absorbency Rate Frequently Asked Questions
Short answers to the questions buyers ask most often about Absorbency Rate.
What does it mean?
time for a droplet to disappear. Working figures for Absorbency Rate normally sit around below 1-3 seconds in mainstream production. Note AATCC 79 absorbency on the tech pack so nobody tests against an older revision.
What value should be specified?
Start from below 1-3 seconds and adjust for the end use of the garment. Record elastane content alongside Absorbency Rate, because blends shift the measured value. A result outside below 1-3 seconds usually points to process drift rather than to the fibre itself.
How is it tested?
AATCC 79 absorbency. Keeping reference values for Absorbency Rate lets suppliers quote without extra sampling rounds. Ask for conditioning details together with AATCC 79 absorbency, 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 Absorbency Rate normally sit around below 1-3 seconds in mainstream production. Note AATCC 79 absorbency 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 Absorbency Rate, because blends shift the measured value. A result outside below 1-3 seconds usually points to process drift rather than to the fibre itself.
