【Scope of application】

The water repellency of the fabric is measured by the Bundesmann rain method, which simulates the water repellency of the fabric when it is subjected to a shower under exercise. The test sample is fixed on a test cup with a wiper device. The artificial rain is 1.5 meters high. By measuring the water content in the water cup and the water content on the surface of the test cloth, the water content of the test sample and the water repellency of the fabric can be evaluated.
