Moisture Management Tester Test Method

The MMT is the only instrument on the market that can precisely measure the liquid management properties of performance and technical fabrics, ensuring the comfort and protection that consumers demand. The Moisture Management Tester (MMT) is an equipment to measure the dynamic liquid transport properties of textiles such as knitted and woven fabrics.

Test Method-AATCC 195

Scope: Method is for the measurement, evaluation and classification of liquid moisture management properties of textile fabrics. The test method produces objective measurements of liquid moisture management properties of knitted, woven and nonwoven textile fabrics.

 

A sample is placed between upper and lower electrical sensors with concentric pins.A test solution is dropped on to the surface and electric conductivity is measured.

 

The test solution moves freely in 3 directions:

Radial spreading on the top surface;

Movement through the specimen from top surface to bottom surface;

Radial spreading on the bottom surface;

 

Several Measurements can be taken such as:

Wetting Time Top;

Wetting Time Bottom;

Top Absorption Rate;

Bottom Absorption Rate;

Top Max Wetted Radius;

Bottom Max Wetted Radius;

Top Spreading Speed;

Bottom Spreading Speed

Accumulative One-way Transport (R)

Overall Liquid Moisture Management Capability (OMMC)

This method may not be applicable to coated, laminated or complex fabric constructions

   

This method may not be applicable to specimens exhibiting high overall absorbent capacity such as terry cloth or other thick knitted and woven fabrics.

 

Fabrics with a linear symmetry such as ribbed knits or fabrics with repellent finishes may exhibit   irregular spreading patterns.
