The instrument uses the Bundesmann rain method to measure the water repellency of fabrics, which simulates the water repellency of fabrics when subjected to a shower under exercise. The test sample is fixed on a test cup with a wiper device. The artificial rain is from 1.5 Falling from a meter-high position, by measuring the water content in the cup and the water content on the surface of the test cloth, the water passing through the test sample and the water repellency of the fabric can be evaluated.
