At present, both at home and abroad, the blue wool fabric dyed with specific dyes is used to measure the light fastness level of the sample, and the light fastness level of textiles is evaluated by visual sensory perception. There are two standards for the color fastness test using the blue wool standard sample against the Color Chart, the new national standard GB/T8427-2008 "Textile Color Fastness Tests Color Fastness to Artificial Light: Xenon Arc" and the standard AATCC implemented in the United States Test Method 16-2003 "Colorfastness to light". Liu Xiaoxia and other scholars' paper "Research Progress in Textile Color Fastness/Sunlight Fastness Testing Technology" analyzed the biological differences and existing problems of domestic and foreign textile color fastness test standards, and outlined the domestic and foreign testing methods for textile color fastness. Research results and progress of testing theory and testing technology. Proposed a way to measure the color fastness of fabrics by using professional photoelectric testing technology and using data expression to replace the artificial control of the blue wool standard to evaluate the color fastness to light of the blue wool standard. degree-level approach.
Conclusion: Through the measurement and research of the color difference of the blue wool standard sun-fading Chengdu and gray card, combined with the research results at home and abroad, and using professional photoelectric testing technology, the light color fastness of the fabric is expressed by data to replace the traditional blue wool. The manual comparison and rating of the color wool standard makes the test more scientific, accurate, objective and convenient, and adapts to the rapid development of science and technology and the requirements for the evaluation of the color fastness to light of fabrics.
