A chalcone compound Isosalipurposide 1 was qualitatively isolated from Acacia cyanophylla yellow flowers. The dyeing of wool fabrics with this chalcone compound as a natural dye has been studied. The effect of dye bath pH and dyeing temperature were investigated. The obtained shades were bright with generally a good fastness. A post-mordanting method was used in the dyeing of wool with this chalcone dye. It was found that, generally, mordanting improved light fastness especially in the case of zinc sulphate.
► Chalcone dyes are very old natural colorants but they are not mainly investigated on textile dyeing.
► A chalcone compound Isosalipurposide was qualitatively isolated from the flowers of Acacia cyanophylla, a cheap and abundantly available plant in Tunisia, and used to dye woollen fibres at different dyeing conditions.
► The results indicate that Isosalipurposide must be used at low dyeing temperatures in order to avoid its degradation and consequently a fall of the colour yield.
► The obtained shades were bright yellow with good colour fastness properties.
► Post-mordanting improved generally light fastness especially in the case of zinc sulphate as mordant.
