æ°™Lighting weatherproof test box for the detection of textiles
The textile sample used for testing in the light exposure chamber, along with the corresponding comparison standard, should be exposed to the same light source simultaneously. This ensures a fair and accurate assessment of light fastness. There are three primary methods to evaluate the light fastness of the test material: first, by comparing the color change in the exposed area with the non-exposed portion of the sample; second, by using the AATCC Color Change Scale to compare the test sample with the original, unexposed material; and third, by employing a color measurement instrument for more precise and objective results. During the test, a series of comparisons are made with the AATCC Blue Wool Lightfastness Standards under identical exposure conditions. These comparisons help determine the lightfastness rating, providing a standardized and reliable measure of how well the material resists fading under artificial light. This process is essential for quality control and ensuring that textiles meet industry standards for durability and performance.
