    DEVELOPMENT OF PRINTING NATURAL FABRICS WITH CURCUMA NATURAL DYE VIA NANOTECHNOLOGY
    (INT JOURNAL PHARMACEUTICAL SCIENCES & RESEARCH, 2017-02) Mosaad, M. M; Abd-El Thalouth, J. I; Tawfik, S; Ragheb, A. A
    The present work is undertaken with a view to harness nanotechnology as one of the most important frontier sciences for development of printing natural fabrics using the most eco-friendly dyes, i.e. natural colors. Curcuma natural dye was studied to clarify the impact of nature of nano-size color particles on size, shape, and particle distribution of the natural dye with comparative studies of the K/S and over all fastness properties of printed samples on natural fabrics (wool, silk and cotton). Results showed that the K/S values of nano samples are higher than original samples, irrespective of the nature of the fabric used and /or the concentration of the coloring matter. Alum mordant incorporated with original curcuma can be omitted, and substituted by nano-curcuma without mordant. K/S values of the pre-mordanting acquired the higher values than the simultaneous mordanting irrespective of the fabric used, or dye particles size used, or curcuma concentrations on using tannic acid mordant. Color fastness to rubbing, and perspiration properties of nano dye is better than the original.
