Flame-retardant fabrics will fade after being used for a long time. What causes fabrics to fade easily? The process is relatively complicated. How to improve and optimize the performance of dyes is an important means to overcome fading of dyed clothes. Flame-retardant fabrics and clothing have been washed many times and exposed to the sun for a long time, causing the dyes on the clothing to photolyze and age, causing the clothing to fade. If the structure of the dye molecule contains many color-helping groups such as amino groups (-NH2) or hydroxyl groups (-OH), oxidation will easily occur and the light fastness will be reduced. When the dye molecules contain groups that can form hydrogen bonds, or groups such as hydroxyl (-COOH), sulfo (-SO3H), nitro (-NO2), etc., the light fastness of the dye will be improved. In addition, the fading of dyed clothing is also related to the structure of the dye molecules. Among dye molecules, the stability is poor, and the fading of dyed clothes is also related to the structure of the dye molecules. In dye molecules, hydrogen atoms with poor stability and strong reactivity can promote the oxidation process. Due to the oxidation or reduction reaction of dye molecules, dyed clothes fade. If cotton fiber fabrics dyed with azo dyes fade in the sun, it is the result of oxidation, but protein fiber fabrics dyed with the same dyes fade in the sun, which is the result of reduction. In short, the reason why dyed clothes fade depends on the affinity of the dye to the fabric fibers, as well as the spectral characteristics of the dye, the concentration of the dye, the dry humidity of the dye, the chemical structure of the dye and other influencing factors. It is not difficult to see that the main reason why dyed clothes fade is determined by the characteristics of the dye.
