Moisture Management Tester

The Moisture Management Tester (MMT) developed by the PolyU is an equipment to test the liquid moisture management capability of textiles such as knitted and woven fabrics. This world leading instrument consists of upper and lower concentric moisture sensors, where the fabric under test is placed in between these two sensors.

A pre-defined amount of test solution (synthetic sweating) is introduced onto the upper side of the fabric, then the test solution will transfer in the materials in three directions:

• Spreading outward on the upper surface of the fabric
• Transferring through the fabric from the upper surface to the bottom surface
• Spreading outward on the lower surface of the fabric and then evaporate

MMT is designed to sense, measure and record the liquid moisture transport behaviors in three multi-directions. A series of indexes are defined and calculated to characterize the liquid moisture management performance of the test sample.
