| Abstract | ||
| A simple method for coating various cellulosic containing fabrics has been developed. Coating layer made of metal nanoparticles and binder were uniformly distributed using direct coating process (flat screen) and time-saving microwave fixation method. A textile coating of viscous paste was prepared using binding agent based on acrylate copolymer, thickening agent based on ammonium polyacrylate and individual inclusion of Ag, ZnO, ZrO2 and TiO2, nanoparticles to provide durable antibacterial properties as well as UV-protection. The multifunctional effect of the coatings, such as antibacterial efficacy, UV-blocking ability, metal and nitrogen content were investigated. Surface alteration of the coated fabrics were identified as well by SEM, EDX analysis. The experimental results suggested that these coated fabrics showed a remarkable improvement in their antimicrobial activity against both Gram-positive and Gram-negative bacteria, irrespective of the used nanoparticle. The finished cellulosic fabrics demonstrated superior UV protection compared to untreated fabrics. | ||
