Spray Rating Tester

Water repellency is a function of fabric that describes the resistance of the fabric to surface wetting & water penetration; in easy words, it measures non-spreading characteristics of water droplets on the material surface.

According to the “American Association of Textile Chemists and Colorists (AATCC),” a visual photographic chart should be used to give a rating on water repellency. Tested material’s final result is given by comparing the chart and appearance of the actual fabric.

Usually, water repellency is gained by treating the material with paraffin, silicon, acid-based melamine, and fluro carbons. This function can be obtained by film coating or lamination. The main object of water repellency is to protect the textile material from getting wet in the case of water exposure.
