The fabric surface moisture resistance tester is a test equipment independently developed and produced by our company qisnun Precision Electromechanical Technology Co., Ltd. This is a cost-effective and comprehensive after-sales service. (water), evaluate the surface moisture resistance of masks, fabrics and other materials, compare the surface of the sample with the standard chart to evaluate the water repellency of the surface of the fabric, the equipment includes a metal frame which allows distilled water to spray through the nozzle until tested Compare the appearance of the sample with the optional photographic scale at 45° and 150 mm below the nozzle.

Main parameters:

1. Spray length: 150mm;

2. Spray time: 25-30s with stopwatch;

3. Water spray volume: 250ml distilled water;

4. The sample clasp is at a 45° angle to the horizontal.

Operational steps:

1. Place the sample on a 152mm diameter metal ring, facing up and make sure the surface is smooth and wrinkle free.

2. Place the metal ring with the sample on the tester storage table, pay attention to the position of the sample when placing it, and make sure that the center of the sample ring is exactly aligned with the center of the spray pattern ring. For some twill, pique, or similar striped structures, when the sample ring is placed on the stage, the direction of the stripes should be placed diagonally to the direction of the water flow.

3. Pour 250ml of deionized water at a temperature of 27±1°C into the funnel of the tester and let it spray on the sample in 25-30 seconds. Whendeionized water is poured, the beaker should not touch the funnel. If the funnel is moved, the pattern and shape of the spray sample will change. The spray time should be between 25 and 30 seconds, otherwise the nozzle should be checked to see if its hole is enlarged or clogged.

4. Hold one side of the sample ring, place the sample face down and quickly tap the other side towards a hard object, then rotate the sample 180° horizontally and quickly hold the original strike location Press again in the original hold area to remove any unwetted water droplets from the sample surface.
