Moisture Management (MMT) How It Changes with Construction and Elastane Content
Moisture Management (MMT) does not stay constant when construction changes. Understanding the direction of change helps during development.
Effect of knit structure
Loop length and density move results first, usually before any yarn change is made. Working figures for Moisture Management (MMT) normally sit around class 3 to 5 for training wear in mainstream production. Note AATCC 195 moisture management tester on the tech pack so nobody tests against an older revision.
Effect of elastane content
More elastane raises recovery but changes the value measured by AATCC 195 moisture management tester, so retest after any blending change. Record elastane content alongside Moisture Management (MMT), because blends shift the measured value. A result outside class 3 to 5 for training wear usually points to process drift rather than to the fibre itself.
Effect of finishing
Heat setting and softeners shift results, which explains differences between a hand sample and bulk. Keeping reference values for Moisture Management (MMT) lets suppliers quote without extra sampling rounds. Ask for conditioning details together with AATCC 195 moisture management tester, since both affect the reading.
Typical range
Working values stay around class 3 to 5 for training wear for mainstream activewear. Working figures for Moisture Management (MMT) normally sit around class 3 to 5 for training wear in mainstream production. Note AATCC 195 moisture management tester on the tech pack so nobody tests against an older revision.
Development advice
Change one variable at a time, then verify against AATCC 195 moisture management tester before moving to the next sample round. Record elastane content alongside Moisture Management (MMT), because blends shift the measured value. A result outside class 3 to 5 for training wear usually points to process drift rather than to the fibre itself.
