In this study, the effect of copper nanoparticles synthesized via a green method on the waterproofing properties of cotton fabric was investigated. Copper nanoparticles were prepared using aqueous solutions with varying concentrations of copper(II) nitrate (1–2%), sucrose (1–3%), and a 2% dispersing agent at pH 5 and 50 °C for one hour. Subsequently, pre-scoured cotton fabrics were treated with the synthesized nanoparticles at 50 °C for 60 minutes. The structure and morphology of both scoured and treated fabrics were characterized using X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), scanning electron microscopy (SEM), and Fourier-transform infrared spectroscopy (FTIR). The particle size of the copper nanoparticles was analyzed by dynamic light scattering (DLS). The waterproofing performance of the samples was evaluated using the standard wicking test (AATCC 197-2013). The results revealed that the most effective waterproofing was achieved when copper nanoparticles were synthesized in a bath containing 1% copper nitrate, 1% sucrose, and 2% dispersing agent, resulting in nanoparticles smaller than 100 nm. This environmentally friendly approach provides a cost-effective and sustainable method for enhancing the functional properties of cotton fabrics, paving the way for advanced and sustainable practices in the textile industry.
