Abstract

The article comprehensively reviews some significant trends in the development of antimicrobial textiles by application of nano metal oxide particles. The green synthesis of silver nanoparticles (AgNPs) was carried out by using Zanthoxylum rhesta plant’s fruit extract for the first time. The green synthesis and in situ deposition of silver nano particles (AgNPs) on cellulose fibers in cotton was carried out by wet and sono chemical methods. The AgNPs and AgNPs deposited cotton fabrics were fully characterized. The crystallite size of particles obtained by both methods was around 37 nm and the hydrodynamic diameters were in the range of 69 to 184nm and 75 to 111nm. Functional cotton with high and durable antibacterial activity by in situ formation of Ag nanoparticles (NPs) onto cotton fabric derived from phytic acid-Ag complex. The route can be divided into two simple steps, adsorption of silver ions onto cellulose matrix with phytic acid as a capture agent and subsequent reduction of Agþ to Ag NPs by sodium borohydride. The successful deposition of Ag NPs on cotton fabric was verified by SEM, EDS and XPS. The developed textile materials have been tested against gram negative bacteria.
