The present work aims of harnessing nanotechnology as one of the most important frontier sciences to develop the printing of natural cotton fabrics using cationic natural dyes, namely berberine dye to confirm the sustainability of the environment for upcoming generations, decrease pollution resultant from textile printing. In this work, Zinc oxide nanoparticles (ZnO NPs) was applied onto cotton fabric by exhaustion method
Natural dye (berberine dye) and natural thickener (tamarind thickener) are used to produce a natural printing paste for printing cotton fabrics by the flat silk screen printing. In this work, three different methods of treating fabrics were used, which are pre-treatment, simultaneous treatment, and post-treatment with ZnO nanoparticles at varying concentrations. The prepared nanoparticles were analyzed using Scanning electronic microscope(SEM), and transmission, electronic microscope(TEM), tensile strength and elongation, bacterial protection, Color strength K/S values, fastness properties, and Ultraviolet protection factor (UPF) were measured on fabric samples.
