ISO 4920 Non Woven Fabric Water Stain Testing Machine, Water Repellency Tester
Product Overview
Water repellency is a critical property of textile fabrics that measures the effectiveness of water resistant/repellent finishing treatments. The YG813 Spray Rating Tester is specifically designed to evaluate this property by spraying a specified volume of distilled water onto test specimens mounted at a 45° angle.
Application: Determines water repellency and surface wetting resistance of fabrics by comparing specimen appearance against standardized photographic charts.
