Development of Excellent Antimicrobial and Wash Durable Fabric With Biosynthesized Silver Nanoparticles Using Soluble Starch, Maize Starch and Rice Extract

ABSTRACT In this study, bioreduction methods for the synthesis of silver nanoparticles (AgNPs) have been used to provide a sustainable, environmentally friendly, and cost‐effective solution. The current work shows that soluble starch, maize starch, and rice extract can be utilized as stabilizing as well as reducing agents for AgNP synthesis. The resulting stabilized AgNPs ranged in size from 10 to 30 nm. Transmission electron microscopy, UV–visible spectrophotometry, and XRD analysis have been used to characterize the size, shape, and structure of the nanoparticles. For biosynthesized AgNPs, UV–visible spectroscopy revealed a surface plasmon resonance peak at 410–420 nm. Analysis of transmission electron microscope images confirms the synthesized AgNPs have a quasi‐spherical shape and uniform surface morphology with a size range from 10 to 30 nm. The cotton substrate was then allowed to get finished with these biosynthesized AgNPs using the pad‐dry‐cure technique, and their antibacterial and antiviral activity was evaluated using the AATCC 100 and ISO 18184 methods, respectively. Wash durability for antibacterial properties has been carried out for the AgNP‐finished fabrics, up to 50 washes. The developed AgNP‐finished fabric revealed excellent antimicrobial and wash‐resistance properties.
