Fabric liquid moisture transport properties in multi-dimensions, called moisture management properties, influence the human perception of moisture sensations significantly. To improve the comfort of today's clothing, especially in sportswear, it is important to know the liquid moisture management properties of the fabric.

1. Fabric liquid moisture transport properties in dimensions, called moisture management properties,
significantly influence human perceptions of moisture sensations. A new method and instrument
called the moisture management tester (MMT) is developed to evaluate textile moisture
management properties. This new method can be used to quantitatively measure liquid moisture
transfer in one step in a fabric in multidirections, where liquid moisture spreads on both surfaces of
the fabric and transfers from one surface to the opposite. Ten indexes are introduced to
characterize the liquid moisture management properties of fabrics. Eight sets of sportswear are
tested with the MMT and the results show that liquid moisture management properties are
significantly different for these fabrics. The objective measurements are compared with subjective
perceptions of moisture sensations during exercise. A fabric’s one-way-transport capacity and its
overall moisture management capacity are significantly correlated with perceptions of clammy and
damp sensations with increased exercise time, indicating that subjective perceptions of moisture
sensations in sweating such as clammy and damp can be predicted by the measurements of the
MMT.
MMT Moisture Management Tester
Testing Standards: AATCC 195, SN 1689.1, GB/T 21655.2
Applications:
The Moisture Management Tester (MMT) is an equipment to measure the dynamic liquid
transport properties of textiles such as knitted and woven fabrics.
Product Information:
Fabric liquid moisture transport properties in multi-dimensions, called moisture management
properties, influence the human perception of moisture sensations significantly. To improve the
comfort of today's clothing, especially in sportswear, it is important to know the liquid moisture
management properties of the fabric.
Test Principle:
The Moisture Management Tester (MMT) is an equipment to measure the dynamic liquid
transport properties of textiles such as knitted and woven fabrics in three dimensions.
1. Absorption Rate - Moisture absorbing time of the fabric’s inner and outer surfaces.
2. One-way Transportation Capability – Liquid moisture one-way transfer from fabric’s inner
surface to outer surface.
3. Spreading/Drying Rate – Speed of liquid moisture spreading on fabric’s inner and outer
surfaces.
MMT permits the measurement of the following indexes:
- Wetting Time Top/Bottom (WTT/WTB)
- Absorption Rate Top/Bottom (TAR/BAR)
- Maximum Wet Radius Top/Bottom (MWRT/MWRB)
- Spreading Speed Top/Bottom (TSS/BSS)
- Accumulative One-Way Transport Capacity (R)
- Overall Moisture Management Capacity (OMMC)
