UV–Vis absorption spectra for blank substrates, AgNP-impregnated, rGO-impregnated, and Ag-rGO-impregnated polyviscose non-woven fabrics, at surface treatment NaBH4(aq) reducing agent concentrations of 200 mmol, both (a) before, and (b) after, laundering durability testing, indicating the surface plasmon resonance (SPR) band where plasmonic AgNP are present.
