New benign colorant nanoparticles were innovated. The innovation is based on reacting the Indigo Blue Vat Dye with a natural clay named montmorillonite (K10) under sonication. A mixture of the dye and clay (1:1) at a ratio was used. The obtained new colorant nanoparticles in the form of hybrid nanocomposites were applied as a nano pigment in printing on various fabrics. The new colorant succeeded in printing silk, wool, cotton, polyester, and nylon as well as their different blends in the presence and absence of binder. Prints of the new colorant were compared with those obtained using commercial pigment. The effect of adding different amounts of binder to the printing paste on major technical properties of the prints was also investigated. Evaluation of the various printed fabrics was performed through monitoring color strength ( K/S ), TEM images, SEM micrographs, and overall fastness properties.
