Spray Tester

The estimation of the test involves visual appreciation of the surface of the fabric (number of absorption points on the surface). The repellency of a garment worn in foul weather conditions is very important.

The estimation of the test involves visual appreciation of the surface of the fabric (number of absorption points on the surface). The repellency of a garment worn in foul weather conditions is very important. The Spray Test method is used for determining the resistance of any fabric, which may or may not have been given a water resistant/ repellant finishing surfacing wetting by water. A good repellency will increase the comfort during use. The repellency tends to decrease during washing, so a re-impregnation of a water repellent product is advised.
