Green printing of wool textiles utilizing green print Paste with natural alkanet dye nanoparticles. The ball-milling technique provides an effective way of generating alkanet-nano particles dye at room temperature and pressure in one step. In this research, we study the effect of alkanet alone and Curcuma dye alone on wool fabric in natural size and nano size and comparing among them. studying K/s of the samples and the properties of fastness. we study the ball milling method to get nanoparticles of alkanet dye. we study the effect of mordants that are attached to fibers before or post-printing of wool fabrics. Regardless of the textile used, nano samples have a K/S value greater than the basic samples. Nano-Curcuma can be replaced for alum mordant with normal Curcuma. K/S values of pre-mordant gained values that were above the simultaneous mordant, regardless of the fabric or size of dye or the quantities of Curcuma in the usage of tannic acid mordant.
