Dyeing is one of the most delightful textile arts which are an important branch in fashion design. Natural dyes is a fascinating phenomenon that enticed researchers to their chemistry and production of fantastic novel hues to explore the point that no other dyes provide a better opportunity teaching how to protect and respect the environment. In this research silk fabric was dyed by a mixture of different percentages of cochineal, turmeric and indigo powders in water-acetone co solvent to possess an ecological acceptable for dye extraction. Extraction and dyeing processes were carried out together in one step at different pH values using sonic energy regarding the promising technique in saving energy. Silk dyeing exhibited a variety of shades according to the evaluated colorimetric data which could be attributed to their resonating structures, where the pH values play important parameter in this phenomenon and control the adsorption capacity of dyes onto silk. So, this research give the chance to produce different hues from the traditional natural dyes to improve the natural dyeing cultural heritage to meet the environmental future demands technology of high quality fantastic dyed patterns through an economical point pf view.
