How to overcome the fading of flame-retardant fabrics?

      Flame retardant fabric will fade for a long time. What is the reason that causes the fabric to fade easily? The process is more complicated.  How to improve and optimize the properties of dyes is an important means to overcome the fading of dyed clothing.  Flame-retardant fabrics and flame-retardant garments have been washed for many times and exposed to the sun for a long time, which makes the dyes on the clothes photolysis and aging, thus making the clothes fade.  In addition, the fading of flame retardant clothing is related to the structure of dye molecules.  Among the dye molecules, the stability is poor. The fading of flame-retardant clothing is also related to the structure of dye molecules.  In dye molecules, the less stable and more reactive hydrogen atoms promote the oxidation process.  Bleaching of dyed clothing due to oxidation or reduction of dye molecules.  For example, cotton fiber fabrics dyed with azo dyes fade in the sun, because of oxidation, and protein fiber fabrics dyed with the same dye fade in the sun, but it is the result of reduction.  In a word, the cause of fading in flame-retardant clothing dyeing depends on the affinity of dyestuff to fabric fiber, the spectral characteristics of dyestuff, the concentration of dyestuff, the dry humidity of dyestuff and the chemical structure of dyestuff.  It is not difficult to see that the main reason for fading clothing is determined by the characteristics of dyestuff.
