MMT Liquid Moisture Management Tester Experience

Author:QINSUN Released in:2023-08 Click:105

The MMT Liquid Moisture Management Tester mainly tests the sweat absorption and diffusion performance of fabrics. The absorption and diffusion of sweat by fabrics directly affects the comfort performance of garments. In order to improve the comfort of garments (especially sportswear fabrics), it is very important to test the liquid moisture management ability of the fabric, which is useful for the evaluation of the absorption of moisture and quick-drying performance of the textile and improving material performance. Qisnun Precision Electromechanical Technology Co., Ltd. is the manufacturer. Greet customers who need to inquire.

The Liquid Moisture Management Tester is used to measure the overall dynamic performance of liquid in knitted and woven fabrics, by testing the absorption rate (moisture absorption time on the front and back of the yousu), unidirectional transmission capacity (the absorption and diffusion of liquid on both sides of the fabric) difference), spreading/drying rate (speed at which the liquid spreads on both sides of the fabric). The liquid moisture management tester includes an upper and lower concentric liquid sensor with multiple probes. The infusion tube in the upper sensor drips a fixed concentration of salt water simulating human sweat evenly over the tissue, and the sensor probes test the humidity between different rings. Resistance, the change in resistance reflects the absorption and diffusion of liquid in the fabric, so as to obtain the ability of the fabric to absorb and diffuse perspiration.

2. Voltage and Current: 110V~230V, 50Hz/60Hz, 0.5A;

3. EnvironmentTest ement: 18℃ to 40℃, 20% to 80% (non-condensing);

4. Pumping time: 20 seconds;

5. Dispensing volume of test liquid: 0.2g +/- 0.01g (users can fine tune the setting);

6 . Liquid conductivity test: 16mS +/-0.2mS;

7. Press value test: 960 grams.

Principle of the test:

The fabric sample is placed horizontally. Water diffuses along the water-soaked surface of the fabric and is transferred from the water-soaked surface of the fabric to the permeable surface, and at the same time diffuses to the permeable surface of the fabric, and the process of Change in water content is a function of time. When the test liquid falls on the water-immersed surface of the sample, the dynamic transfer of liquid water is measured by the sensor in close contact with the sample, and a series of performance indicators are calculated to assess the amoisture absorption, quickly. drying, perspiration and other textile properties. .

Put the sample into the instrument, with the side in contact with the skin up, pour a certain amount of saline solution into the center of the side of the tissue in contact with the skin, to simulate the process. sweating of the human body. Sensors on both sides of the sample measure the conductivity of the water in each ring (diameters are 5mm, 10mm, 15mm, 20mm, 25mm and 30mm). Fabric moisture and water conductivity increased after a 2 minute test cycle. Through a series of calculations, the tester can obtain accurate readings of the wetting time, water absorption rate, wetting radius and diffusion rate of the fabric from the side in contact with the skin, as well as the cumulative one-way transfer capacity and the overall liquid. moisture management capacity (OMMC) of the fabric .

The trans indexfert and overall liquid moisture management capabilities are attracting the attention of many technical fabric manufacturers. Research has shown that using these numbers and the \"fingerprint\" provided by the Liquid Moisture Management Tester, users can classify fabrics into 7 levels: Water Repellent, Water Repellent, Slow Absorb/Slow Dry, Absorbency fast/slow drying, fast/fast absorbing. drying, moisture penetration and moisture management of liquids. After classifying fabrics according to their end application, users can compare different fabrics according to the index measured by the liquid moisture management tester. At this point, people just know which type of fabric is required by the environment of use, without having to perform tedious physiological tests.
