We usually can do below test:
1.Water repellent test (WR): Splash a little water on fabric and see if the water ball can roll or the fabric surface is wet.
2. Waterproof test (WP): How much heavy rain will go through fabric and make inside wet. There are two ways to test by machine: before washing and after washing.
3. Moisture proofness test (MP): it means how fast the body sweat can go out through fabric.
