The multifunctional natural fabrics as colored, antibacterial and UV-protective fabrics were effectively prepared by in-situ incorporation of silver nanoparticles (Ag NPs) into the fabric matrix. Cotton and wool fabrics were used as natural fabrics and trisodium citrate was utilized as reductant for Ag+ and stabilizer for Ag NPs. The formation of Ag NPs in the residual solutions was confirmed by UV/Vis spectra. Ag NPs on fabrics were shown by scanning electron microscopy and their size was in range of 20-90 nm and 70 150 nm for cotton and wool fabrics, respectively. X-ray photoelectron spectroscopy confirmed the stabilization action of citrate. As a result of surface plasmon resonance of Ag NPs, colored fabrics were produced with good fastness properties. Functional properties of treated fabrics indicate that, the in-situ incorporation of Ag NPs into fabric matrix was simultaneously imparted multifunctional properties (colorant, antibacterial action and UV-protection) into natural fabrics concurrently.
