This research focuses on green synthesis of AgNPs using environmentally benign reagents in minimal time paves the way for future studies on AgNPs toxicity without risking interference from potentially toxic reagents and capping agents. The use of this technique to treat nylon fabric may lead to new coloration technique and other functional improvement. Our method a totally green approach toward the rapid synthesis and evergreen protocol for the green synthesis of silver nanoparticles AgNPs from aqueous solution of silver nitrate using available sugar as reducing agents in a single-pot, in the presence of sunlight . Green synthesized AgNPs were characterized by Scaning electron microscopy (SEM) , Transmission electron microscopy (TEM), , Energy dispersive spectroscopy (EDS), Fourier transform infrared (FTIR) and x-ray diffraction (XRD) analysis. The dyeing behavior of green AgNPs treated nylon fabric with Acid Black 172 (AB 172) has been studied and the build up of dye, measured as exhaustion percentage (E%) , increases the dye affinity (from 77.38 % to 99.79 %) towards the fabric. Dye adsorption rate constants according to pseudo-first order, pseudo-second order, and intra-particle diffusion kinetic models were calculated. Moreover, the dye adsorption equilibrium data were fitted well to the Freundlich isotherm rather than Langmuir isotherm. The overall adsorption process follow pseudo-second order kinetics, Intraparticle diffusion and Elovich model. The green synthesized AgNPs treatment produces a nylon fabric with advanced color fastness and antibacterial properties enabling them to improve human health care and reducing temperature, the environmental impacts, fabric damage, amount of dyestuff used and saving energy of conventional dyeing of nylon fabrics.
