An environmentally friendly synthesis of silver nanoparticle was developed using green tea extract. Further silver nanoparticles AgNPs were deposited and firmly adhered onto pure cotton, polycotton, and polyester textiles using dip coating method. The effect of ZnO and SiO2 on the adsorption ability of AgNPs on textile were studied. Characterization of AgNPs was carried out using UV-Visible/ reflectance spectroscopy and XRD. The average particle size was 16 nm, and synthesized AgNPs with a face cubic crystalline nature were observed by XRD. The reflectance spectra of the textile confirmed that ZnO and SiO2 increase the adhesion ability of AgNPs on different textiles. The antimicrobial activity of AgNPs coated fabrics were evaluated against E. coli and Aspergillus niger. Most fabrics showed good antimicrobial activity. Moreover, AgNPs/SiO2 coated polycotton and polyester show the highest antibacterial activity against E. coli. In addition, AgNPs/SiO2 coated polyester and AgNPs/ZnO coated cotton revealed high antifungal activity against Aspergillus niger.
