The Effects of Cationization on Dyeing Properties of Cotton Fabric Dyed with Marigold and Rose

A cationizing agent was used for increasing the color yield, in terms of the Kubelka–Munk values (color strength, K/S). Cotton fabrics were dyed using the extract of waste marigold and rose. This work was to study the optimum of time, temperature and concentration in cationizing process on dyed cotton. The K/S and color values (L*, a*, b*) were measured to discover the suitable condition from color value and color strength estimation, cotton fabric cationized with 10 g/L of cationizing-agent concentration for 30 minutes at the 50°C showed the highest K/S. In case of roses, the best condition is treated with cationizing-agent concentration of 15 g/L for 15 minutes at 50°C. The obtainable results revealed that the color strength of cationized cotton fabrics were increased when compared to K/S of untreated cotton up to 34.26% and 331.91% for marigold and rose dyes, respectively, and the obtainable color of cationized cotton fabrics were brighter as compared to the untreated cotton.
