A new copper(II) nitrate complex for dyeing the wool and nylon fibers

In this study, a new nanosized copper(II) nitrate bearing phosphoramide ligand was synthesized and used for dyeing the wool and nylon fibers. The prepared dye was characterized by elemental analysis, 13C, 31P, 1H NMR and FT-IR spectral studies. The dyed fibers were examined by light fastness and wash fastness tests so that very good wash fastness but poor light fastness results were obtained. The dyeing ability of this complex has been evaluated with K/S diagrams and determination of LAB parameters
