► 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.
This study aims to evaluate the fluorescence property of wool fabric dyed with indicaxanthin, natural dye. Fluorescence measurements have been developed on wool samples before and after dyeing. The emission spectrum of the undyed wool fabric does not illustrate any peak and in the contrary, dyed wool sample present interesting photoluminescence property and the highest value was recorded at 576nm. Aging behavior upon exposure to light irradiation and upon washing was studied and it has been proved that samples keep interesting fluorescence properties.
