The present work is undertaken with a view to establish the best practice (formulation/conditions) for processing of new hybrid nanocomposite as new colorant .Synthesis of the new colorants is based on intercalation of Indigo Blue Vat dye with the silicate-layered nanocomposite (SLNC) which is a natural clay known as montmorillonite (MMT). Current study addresses the ultrafine nanoparticles formed under the effect of ultrasound technology on Indigo Blue Vat dye in presence of the clay. The formation of Indigo Blue Vat dye /clay hybrid nanocomposite under different formulations and conditions are studied in order to achieve the best practice for optimization of the synthesis of the new colorant based on Indigo Blue Vat dye/clay hybrid nanocomposite. New colorants obtained by such synthesis are characterized, analysed and tested using state͟ of the̶ art tools. Ability of these ultrafine colorants to produce prints on cotton textiles is also studied. 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.
