Of all the color fastness tests, testing the fabric's response to light is probably one of the most important test items. Of course, for manufacturers, the performance of fabrics in washing, dry cleaning, rubbing, wicking, and subsequent exposure to different types of solutions is crucial information.
But because fabrics are sensitive to light and unpredictable, reliable testing is critical.
▶Test method for colour fastness to sunlight (light) of textiles
Main Measurement Range
1. The light fastness test of dyes: the light fastness test of dyes is carried out under the conditions of light (wavelength is 380nm ~ 750nm) and certain temperature and humidity.(xenon fastness test chamber)
2. Weather fastness test of dyestuff: under the combined influence of light (wavelength is 380nm～750nm) and certain temperature, humidity and rain, the weather fastness of dyestuff is determined.
3. Weather fastness test of textiles, etc.: Under the combined action of light (wavelength: visible light 380nm ~ 750nm; ultraviolet light 300nm ~ 380nm) and climatic conditions, determine the weather fastness of textiles, etc.
