Silver nanoparticles (AgNPs) were greenly synthesized over aramid fabrics from wild mushroom (Fomes fomentarius) to develop colorful products. The localized surface plasmon resonance characteristics of AgNPs provided versatile coloration effects on fabrics, with improved color strength (K/S) and other colorimetric values (L*, a*, and b*). The stability of the colored materials was also investigated in terms of color fastness to wash and rubbing (both wet and dry states). The characteristics of deposited AgNPs over aramid materials were characterized by X-ray fluorescence spectroscopy testing of solid fabric samples. Morphological properties of the aramid substrates were investigated using SEM (scanning electron microscopy) testing to check the surfaces both for nanosilver-treated and untreated materials. Moreover, the developed nanoparticles were also confirmed further using SEM-deployed energy-dispersive X-ray spectroscopy and elemental mapping analysis. The chemical bonding between the aramid fiber and deposited AgNPs was tested using Fourier infrared spectroscopy analysis. The thermal stability of the aramid fabrics was examined in order to investigate their behavior when exposed to heat in terms of thermogravimetric analysis and derivative thermogravimetry analysis. The K/S values and darkness values were increasing with the increased loading of the nanosilver precursor. Moreover, statistical analysis was also conducted in terms of the coefficient of variation (R2) to understand the significance of the connection between the nanosilver loading and coloration characteristics, and found a significant relationship. Overall, a novel, sustainable, and facile biosynthesis route of AgNPs is reported in this current research.
