Abstract

The synthesis of the. dye o,o′-dihydroxyazo-HMFAN and its chromium and cobalt complexes, is described. These dyes have been applied to nylon 6 and wool fabrics. Dye exhaustion has been calculated according to the absorbances of the original and residual dyes in the dyebath. The fastness to light, washing and rubbing of the dyed fabrics have been measured. The spectral characterisation of these dyes is investigated by IR and UV/Vis spectroscopic techniques and thin-layer chromatography.
