Effect of Adsorption of Silver Nanoparticles on Wool Fabric and Its UV-Blocking Property
Silver nanoparticles were immobilized on wool fabrics by electrostatic adsorption method. In this study 3-chloro-2-hydroxypropyltrimethylammonium chloride was used as a cationic agent to cationic wool fabric by a pad-dry-cure process. The cationic wool samples were immersed in dilute solutions of silver nanoparticles to form a thin film, and the UV protection property of the fabric was investigated. The SEM images and UV-vis spectra showed the typical silver nanoparticles were nearly spherical, and exhibited one absorption band at 392 nm. SEM and FTIR were employed to probe the morphology and composition of the treated wool fabrics. The SEM and FTIR analysis confirmed that silver nanoparticles were successfully uniform deposition to the surface of the wool fabrics. UV-vis spectra showed that the treated fabrics exhibited excellent UV-blocking properties in comparison with the untreated wool fabrics.
