Spectral characterization of wool fabric dyed with indicaxanthin natural dye: Study of the fluorescence property

► We analyze the chromatic effects due to the interactions of indicaxanthin dye with wool fiber. ► Fluorescence measurements have been developed on wool samples before and after dyeing. ► Only the dyed wool sample present interesting photoluminescence property. ► Aging behavior upon exposure to light irradiation and upon washing was studied. ► It has been proved that samples keep interesting fluorescence properties.
