Abstract

The effect of three different crown ethers on photodegradation and stable free radical concentration generated by light exposure has been studied on two cotton cellulose-reactive azo dye systems, with and without covalent bond between dye and fibre, respectively. A crown ether which decelerated the photofading of the dyed fabric increased the stable free radical content of the system under exposure to light, whereas those crown ethers which accelerated the photofading decreased the stable free radical content.
