The various applications of silver nanoparticles (AgNPs) are brutally hampered in the practical field due to their instability and aggregation features. Thus, highly stable colloidal AgNPs were produced in obedience to the principle of 'green chemistry' that uses natural dyes extracted from gardenia fruits as stabilizing and simultaneously as reducing agents. The effect of operating conditions on the synthesis of AgNPs was studied using a one-variable-at-a-time technique to maximize the growth of particles.The analysis of AgNPs produced at optimum reaction parameters discovered that the particles are face-centered cubic metallic silver, mostly in spherical shapes, nanoranged in diameter (23.4 ± 6.4 nm) with a confined size distribution, enormously crystalline surface (d-spacing = 0.233 nm), firmly stabilized (zeta potential = À29.0 mV) by a thin membrane of gardenia phytochemicals. They exhibited significant bacterial reduction inhibition against the growth of Escherichia coli and Staphylococcus aureus owing to the strong antibacterial function of nanosilver.

“…AgNPs exhibit bright and fascinating color appearances due to the LSPR properties (Mahmud et al, 2018). This LSPR feature of AgNPs facilitates the diversified color appearances from brilliant light to bright colors on the OCFs surfaces after their in situ deposition without applying any traditional/synthetic dyestuffs.…”

PurposeFunctionalization of organic cotton fabrics (OCFs) by in situ deposition of chitosan reduced-stabilized silver nanoparticles (AgNPs). No other toxic chemicals used to warrant an ecofriendly synthesis protocol. Human toxicity of silver systematically avoided to use as textile clothing. Primary colors (nearly-red, yellow and blue) were imparted on OCFs via localized surface plasmon resonance (LSPR) of AgNPs. Decent mechanical properties and laundering durability in terms of antibacterial/fastness test improved mechanical properties.Design/methodology/approachSilver nanoparticles can be synthesized by using silver nitrate along with commercially available chitosan. Due to the surface LSPR property of silver nanoparticles, it exhibits versatile colors depending on the synthesizing procedures. The coloration occurs due to the electrostatic interaction between the AgNPs and chitosan-treated OCF. The nanotreated fabrics provide excellent mechanical properties with improved antibacterial effects.FindingsX-ray fluorescence (XRF) analysis quantifies the developed materials in the substrates. Scanning electron microscopy (SEM) characterization indicates the appearance and morphologies of silver nanoparticles into the fabric surface after the coloration process. It proves that the treated cotton knit fabric exhibits the LSPR optical features of AgNPs. The antibacterial and mechanical properties confirm the improved functionality of products.Originality/valueImproved mechanical properties, antibacterial performances and coloration effects on organic cotton substrates in terms of chitosan-mediated nanosilver are not yet studied.

This study presents the functionalization of organic cotton fabric (OCF) by green synthesized silver nanoparticles (AgNPs). Nontoxic sodium alginate (SA) was utilized as a reducing and stabilizing agent. Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), UV–vis spectroscopy, color coordinates, Ag content, and release (%) were used for characterization of the AgNPs and the functionalized OCF. The results reveal that AgNPs were successfully deposited on the surface fibrils of the OCF. Optimistic colors were observed from the treated OCF due to the localized surface plasmon resonance (SPR) of AgNPs. Moreover, studies of mechanical properties in terms of breaking strength and elongation at break (%), crease recovery angle, bending length, and hand-feel were performed, and better results were found in comparison with the control OCF. It was also observed that the presence of AgNPs significantly enhanced the UV resistance and antibacterial activity of the OCF.
