Abstract
Micro-fading spectrometry is a technique that combines visible reflectance spectroscopy and accelerated light aging testing. Therefore, it is a useful tool for determining the light-stability of dyes applied on textile substrates in a relatively short amount of time. Traditional accelerated light aging methods usually require controlling many variables such as time and intensity of illumination, correct positioning of the sample during irradiation, and reproducible spot selection for each subsequent spectrocolorimetric measurement. The use of micro-fade testing as an alternative way of conducting light-fastness assessments of dye/textile systems has been explored. The results indicate that the technique is suitable for testing the color stability of cultural heritage materials and industrially manufactured textiles since it is a direct and non-contact method that takes into account the aforementioned experimental variables.
