The growing concern for the personal health and hygiene has created the necessity of acquiring wool fabric antibacterial activity. Silicon dioxide nanoparticles (SiO2 NPs) have appropriate features to enhance the functional properties of wool fabrics, especially with polymer application. In this study efficient coating using polyethylene glycol (PEG2000) and SiO2 NPs were used for imparting antibacterial properties to treated fabrics. All the treatments were carried out using both conventional and ultrasound techniques. The physical and chemical properties were evaluated using FTIR, XRD, and SEM. The result indicated that treated wool fabrics by PEG/SiO2 NPs improved the dyeability and antibacterial of the fabrics and also enhanced its mechanical properties. Furthermore, it is believed that the ultrasound radiation causes homogeneous distribution of cross-links and polymerization throughout the wool surface. This offers considerable advantages compared to conventional treatment.
