The AATCC 169-0 standard describes an accelerated aging test method for Spinning & weaving products to evaluate a material's resistance to degradation by UV irradiation. A Xenon-arc lamp is used to simulate outdoor sunlight and test the colour fastness and intensity of a sample after exposure for a specific period of time. This standard helps evaluate the durability of Spinning & weaving products in the actual use environment, ensuring their performance and Appearance stability over long-term use. Test conditions include temperature, Humidity, UV irradiance, etc.
