Absorbency Rate Setting It Correctly on a Tech Pack
Absorbency Rate should be written into the tech pack with a value, a tolerance and a method. This removes ambiguity from quotations.
Definition to agree
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.
Target value
Open the specification at below 1-3 seconds, adjusted to the end use. 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.

Method line
Always pair the target with AATCC 79 absorbency so the mill and the laboratory test the same way. 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.
Tolerance line
State plus or minus limits to keep production realistic while protecting the requirement. 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.
Approval step
Approve the result on pre-production bulk rather than on development fabric only. 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.
