T HE presented work studied the synthesis of a new multifunctional smart nanocolorant based on natural clay (montmorillonite K10), chitosan and metal nanoparticles (CuO, ZnO, TiO 2 or Ag) using ultrasonic technology. The prepared nanocolorants were characterized for their particle size and properties. These nanocolrants were used in printing paste for application to cotton fabric before and after sonication. Surface morphology antibacterial activity and fastness properties were evaluated for treated fabrics. It is observed that fabrics printed with prepared materials after sonication acquire much smoother surface than those printed with prepared materials before sonication. The new hybrid particles are small enough to diffuse into fibers and they create high fastness properties. In addition, printed fabrics with hybrids particles are highly fixed on the fabric surface.
ZnO, TiO2, and CuO nanoparticles were immobilized onto the cotton and wool fabrics at room temperature. The antimicrobial activity of dyed cotton and wool fabrics with reactive dye against S-aureus, E-coli, and C-candida were measured by the optical density method. It was observed that the killing of bacteria and the bacterial cell damage were harmed efficiently. The effect of pre-treatment of cotton and wool fabrics with different NPs metal oxides on the color strength of dyed fabrics was studied. Color strength (K/S) and colorimetric data (L*, a*, and b*) were measured at specific λmax. Besides, washing, rubbing, perspiration, and lightfastness of dyed cotton and wool fabrics were determined. UV blocking and self-cleaning of the treated fabrics were measured accordingly. The obtained results of the pre-treated fabrics with ZnO, TiO2, and CuO nanoparticles would support the current research outputs as a potential production of protective textile.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
