| Abstract | ||||
| Traditional indigo dyeing processes use various chemicals. Due to the increased awareness of environmental aspects, the interest in eco-friendly processing has become a priority. Regarding the indigo dyeing process, in this study, the traditional reduction process will be carried out without the environmentally unfavorable sodium dithionite which will be replaced with the determinant role of ultra-sonication in the miniaturization of indigo dye particle size. The research presented herein is a continuity of our interest to adopt synthesis, characterization, and applications of radically new nano-colorants. The synthesis involves nano-processing of a quaternary mixture consisting of Indigo Blue Vat dye/Natural clay (Montmorillonite MMT(K10)/Chitosan/Metal or Metal oxide Nanoparticles. Nano-colorants obtained acquire unique properties and sound performance. Further information concerning the contribution of other factors on properties, performance, and sustainability is the major target of current work. Role of sonication during nano-processing of the composite of the nano-colorant components, the importance of the number of nanometal particles in the synthesis, and sequence of addition of the nanometal particles. This and another potential of the research create the hope for inner nano-pigment. | ||||
