Methods for the synthesis of copper nanoparticles by reducing copper sulfate in an aqueous medium in the presence of sucrose are considered. The
determination of optimal synthesis conditions, the antibacterial activity of copper nanoparticles was studied, the influence of various factors was established: the concentrations of the reagents used, pH of the medium, temperature on the process of recovery of copper ions. A method has been developed for the antimicrobial finishing of sucrose-based cellulosic textile material in a composition with copper sulfate for sizing cotton to improve the antimicrobial properties of cellulosic textile material. A simple and environmentally friendly method is proposed for producing concentrated
(about 0.01 mol/l) hydrosols containing copper nanoparticles of size 30-40 nm. The method is based on the reduction of Cu2+ ions in aqueous sodium solutions in the presence of sucrose.
Keywords: cellulose textile materials, modification, copper nanoparticles, antibacterial properties, sucrose.
