Abstract
Novel orange reactive dyes containing a built-in benzophenone moiety had been synthesized in four steps and characterized using electrospray mass spectroscopy analysis. They were applied to dye cotton fabrics and evaluated for their ability to give protection against the harmful UV radiation. The results showed that the anti-ultraviolet properties of the dyed cotton with the dyes containing a built-in hydroxybenzophenone moiety were significantly improved. However, the incorporation of methyl or ethyl groups into the benzophenone moiety did not show a beneficial effect on the UPF values of dyed cotton.
