Sharing on Testing Methods for Water and Oil Repellent Agents: A Comprehensive Overview
In the race to upgrade fabric functionalities, the performance of water and oil repellent agents relies heavily on scientific testing methods. Let’s take a quick look at the core testing dimensions of water and oil repellent agents in the Chinese market:
Waterproof Performance, the foundation, is evaluated through the spray method to check surface water repellency, the water bead retention test to measure water droplet holding capacity, and the water droplet pe*******on test to verify deep-level impermeability.
Washing Durability is crucial. Processes like post-washing drying and air-drying/drying in the shade after washing ensure the agent remains effective after multiple washes.
Anti-siphon Performance is tested in both static and dynamic scenarios to ensure the fabric can prevent water siphon pe*******on under different working conditions.
Meanwhile, indicators like hand feel and hand-scratching white effect, which affect wearing experience and style, are also assessed.
There are also “other tests” such as water pressure resistance test, peel strength, oil resistance & easy stain removal, and color change, which comprehensively check from aspects like strength, cleanability, and color fastness.
These testing methods together form the quality benchmark for water and oil repellent agents. What are the testing methods you commonly use in practical applications? Welcome to share and discuss~
