The present work involves the optimization of extraction and dyeing recipes to standardize the procedure for natural dye obtained from the roots of Ratanjot (Onosma echiodes) using ultrasonic waves. The resultant dye obtained at optimized extraction conditions was applied on wool fabric to study the effect of temperature, dye concentration, time and dyeing pH. Optical density and colour strength (K/S value) were studied for evaluation of optimum extraction and dyeing conditions. It was observed that extraction and dyeing parameters have significant effect on colour characteristics of dyed wool fabric. The optimized extraction conditions were; dye extraction pH 7, extraction time 60 min and temperature 60ºC while optimized dyeing parameters were; dyeing temperature 60°C,  dye concentration 2 g/g, dyeing time 75 min and dyeing pH 5. It was also observed that the optimum dye extraction time and pH is same with the conventional heating method but there is reduction in the temperature (60°C), dyeing time and dye concentration consumption in ultrasonic extraction and dyeing method, thus saves the energy, time and amount of dye requirement. Therefore, ultrasound wave represents a promising method for increasing diffusion of dye by the effect of cavitation, as well as for improving the effectiveness of processes as compare to conventional heating method.

Researchers are continuously exploring new candidates in the field of natural dyeing to lighten the burden of synthetic dyestuff on living organisms. In this research, novel natural dye was explored using the Caulis spatholobi plant. The extraction was carried out through the conventional extraction method in the aqueous medium. Various parameters of the natural dye extraction process, such as the material-to-liquor ratio, pH, time and temperature, were optimized to 1:40, 12, 120 min and 100℃, respectively. The extract was filtered twice and used for the characterization and dyeing of wool fabric. The extract was characterized using Fourier transform infrared spectroscopy for the determination of dominant functional groups. Natural dyeing of wool was carried out with and without metal mordants, such as aluminum sulfate, ferrous sulfate, copper sulfate and zinc sulfate. Pre-mordanting, meta-mordanting and post-mordanting techniques were employed. The performances of dyed fabrics were evaluated in terms of color strength K/ S values. The fastness properties of dyed fabrics were also measured. The dyed fabric showed various color shades based on the type of mordant used. Furthermore, enhancement in the colorfastness was observed with mordanting.
