Drying Rate Setting It Correctly on a Tech Pack
Drying 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 wet fabric to reach equilibrium. Working figures for Drying Rate normally sit around under 30 minutes for lightweight knits in mainstream production. Note AATCC 199 drying rate on the tech pack so nobody tests against an older revision.
Target value
Open the specification at under 30 minutes for lightweight knits, adjusted to the end use. Record elastane content alongside Drying Rate, because blends shift the measured value. A result outside under 30 minutes for lightweight knits usually points to process drift rather than to the fibre itself.
Method line
Always pair the target with AATCC 199 drying rate so the mill and the laboratory test the same way. Keeping reference values for Drying Rate lets suppliers quote without extra sampling rounds. Ask for conditioning details together with AATCC 199 drying rate, since both affect the reading.
Tolerance line
State plus or minus limits to keep production realistic while protecting the requirement. Working figures for Drying Rate normally sit around under 30 minutes for lightweight knits in mainstream production. Note AATCC 199 drying rate 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 Drying Rate, because blends shift the measured value. A result outside under 30 minutes for lightweight knits usually points to process drift rather than to the fibre itself.
