Experimental Principle of MMT Tester for Liquid Moisture Control

MMT Liquid Moisture Management Tester mainly tests the absorption and diffusion performance of sweat in fabrics. The absorption and diffusion of sweat through fabrics has a direct impact on the comfort performance of clothing. In order to improve the comfort of clothing (especially sportswear fabrics), It is very important to test the moisture management ability of the fabric, which is useful for the evaluation of the moisture absorption and quick-drying performance of the textile and the improvement of the material performance.QINSUN is the manufacturer.Welcome customers who have questions. 8drTextile Testing Instruments, Testing Equipment Manufacturer

The dust sample is placed horizontally. After the liquid water comes into contact with the soaked surface, the liquid water will diffuse along the soaked surface of the fabric and transfer from the soaked surface of the fabric to the dpermeable surface , and at the same time diffuse on the permeating surface of the substance. The water content change process is a function of time. When the test liquid is dropped into the water-immersed surface of the sample, the dynamic transfer of liquid water is measured using the sensor in close contact with the sample, and a series of performance indicators are calculated to evaluate the moisture absorption, quickly - drying, perspiration and other properties of the textile. 8drTextile Testing Instruments, Testing Equipment Manufacturer

Place the sample in the instrument, with the side in contact with the skin facing upwards, and pour a certain amount of saline into the center of the side of the substance in contact with the skin , simulating the process of sweating of the human body. The sensors on both sides of the sample measure them in each ring

(diameters are 5mm, 10mm ,15mm, 20mm, 25mm and 30mm) water conductivity. The moisture and water conductivity of the fabric increased after the test was run for 2 minutes. Through a series of calculations, the tester can get accurate measurements of wetting time, water absorption rate, wetting radius, and diffusion rate of the fabric on the side in contact with the skin, as well as cumulative one-way transfer capacity and overall fluid moisture management capacity (OMMC). ) of the substance. 8drTextile Testing Instruments, Testing Equipment Manufacturer

Its transfer index and overall fluid moisture control capabilities are attracting the attention of many manufacturers of technical fabrics. Research has shown that using these numbers and the fingerprint of the Liquid Moisture Management Tester, users can classify fabrics into 7 levels: water repellent, water repellent, slow absorbing/slow drying, fast absorbing/slow drying, fast absorbing/fast drying, moisture penetration and moisture regulation of liquids. After classifying substances according to their end use, users can compare different substances by the index measured by the liquid moisture control tester. At this point, people will know which is the substance the environment needs, without doing tedious tests. 8drTextile Testing Instruments, Testing Equipment Manufacturer
