Moisture Management Tester TF128

Test Specification

The Moisture Management Tester is used to test and evaluate the liquid water dynamic transfer performance of textiles. This testing method provides an objective method for measuring the liquid water dynamic transfer properties of knitted fabrics, woven fabrics and nonwovens, and is used in the quality control of fabrics, the research and development of new functional fabrics and garments, etc. This method is not used to test the transport performance of vapor water. This testing method is not suitable for coated fabrics, glued fabrics or fabrics of complex structures. This testing method is not suitable for fabrics with high water absorbability such as woolen fabrics or thick fabrics.

Test Principle

When the fabric sample is placed horizontally, the liquid water contacts with the soaking surface, then diffuses along the soaking surface of the fabric, then penetrates from the soaking surface of the fabric to the permeable surface, and finally diffuses on the permeable surface of the fabric. After dripping the test solution into the soaking surface of the sample, test the dynamic transfer of the liquid water by using the sensor in close contact with the sample, and calculate the related performance indexes, so as to evaluate the moisture absorption, drying and sweating performance of the textiles.

Terminology Definition

Absorption Speed: When the water content changes, the average absorption velocity of the liquid on the upper and lower surface of the sample during the testing process.

Lower Surface: For the purposes of this test, it refers to the surface that the specimen facing the lower layer sensor, as well as the front of the fabric or the outer surface of the garment.

Maximum Wetting Radius: The maximum radius of the wetting area at the end of a given time when the fabric begins to soak.

Overall Moisture Management Capability: The comprehensive performance of liquid water dynamic transfer in fabric. The water absorption rate of the fabric permeation surface, accumulative one-way transport capacity and spreading speed of the permeation surface were synthesized.

Diffusion Velocity: The rate accumulative value from the test solution drop down to the fabric surface until the fabric is wetted with the maximum area.

Wetting Time: The time from the beginning of the test to the wetting of the upper and lower surfaces of the sample and expressed in seconds.
