Optimization of Dyeing Process Using Achillea pachycephala as a Natural Dye for Wool Fibers

The yellow flower of Achillea pachycephala plant, a new source of natural dye, was introduced and its dyeability on wool yarn fibers was studied. Central composite design (CCD) and response surface methodology (RSM) have been applied to design experimental runs to evaluate the interactive effects of...
