Abstract :This study investigates the optimal dyeing concentrations of cotton, wool, and viscose fabrics with sodium copper chlorophyllin (SCC). Using SSC above the optimal concentration increases the amount of SCC in the wastewater, which is a disadvantage. Pre-finished 100% cotton, wool and viscose 1 x 1 rib knitted fabrics were dyed with varying SCC concentrations. Optimal dyeing concentrations were determined using UV-Vis spectrophotometry, showing dye absorption decreasing as SCC concentration increases. Equilibrium was reached at approximately 7 ml/L for cotton and viscose, and 3 ml/L for wool. Color measurement values and K/S values of the dyed samples were obtained according to the CIELab color system. The K/S values of dyed cotton, viscose, and wool fabrics rose as the concentration of SCC increased, reaching a peak at 9 ml/L for viscose and 12 ml/L for cotton and wool. Rubbing and perspiration fastness were rated good to excellent.
