Copper and silver metal nanoparticles and their compounds are of great significance across all industries due to their numerous properties and wide-ranging applications. Consequently, their synthesis has garnered considerable attention. Among the existing methods for nanoparticle synthesis, the reduction of metal salts in the presence of a stabilizer leads to the production of nanoparticles with controlled sizes. The use of green synthesis methods has attracted interest, as these approaches are environmentally friendly and employ natural, non-toxic materials. In this study, the simultaneous hybrid synthesis of silver/copper nanoparticles was carried out via the reduction of metal salts using a green method. In addition to nanoparticle synthesis, the water-repellent properties of the treated samples were investigated. A natural reducing agent, maltose, along with silver and copper salts at various concentrations, was utilized. To control nanoparticle size, ascorbic acid was employed as a reducing and stabilizing agent at a constant concentration on cotton samples. For further characterization of the samples, tests including reflectance spectroscopy, wicking test, elemental analysis (EDX), scanning electron microscopy (SEM), X-ray diffraction (XRD), tensile strength, abrasion resistance, and bending stiffness were performed. The results obtained from these tests indicated significant differences among the samples. It was determined that among the specimens, the A 1 /C 1 .M 1 sample exhibited superior water repellency and resistance, which is attributed to the synthesized particle size (77.14 nm) in this particular sample.
