•Multi-functionalization of natural fabrics was achieved by in-situ synthesis of Ag NPs.•The Ag NPs were synthesized into the fabric surface by using sodium citrate as reducer for Ag+.•Accoridng to their surface plasmon resonance, Ag NPs was used to produce colored fabrics with different shades.•The Ag treated fabrics exhibit good color fastness, antimicrobial action and UV protection.
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.
