Product Description

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.

The Test is especially suitable for measuring the water-resistant or water-repellent efficiency of finishes applied to fabrics particularly plain-woven fabrics. It is not intended to predict the rain penetration resistance of fabrics, since it does not measure penetration of water through the fabric.

Before testing is carried out, the specimen is conditioned for at least 24hr in the standard atmosphere for testing textiles. The Spray rating is determined by comparing the appearance of the specimen with AATCC & ISO Spray Test Rating Chart.

With the spray tester by Presto, we are now capable of testing the repelling properties of the garments and fabrics with much ease. The instrument has a very simple operation and yet gives effective test analysis.
