Nanotechnology has a widespread application in textile fields especially in technical textiles, finishing, and dyeing processes. Accordingly, in this research, we investigated the effect of nanogold as a mordant for woolen textile dyeing. The purpose of this research was to produce a multifunctional woolen textile. Therefore, after the yarn purification and neutralization, the yarns were pre-treated with nanogold (60ppm) in boiling water for 1 hour and then were dyed (on chrome method). Then nanoparticles and colorant yarns were assessed through DLS, EDS,FESEM, SEM, washing fastness, light fastness, and antibacterial property. The obtained results indicated that nanogold was absorbed by the wool and the washing and light fastness were enhanced. Besides, nanogold did not show any staining or roughness on the yarns. In addition, the yarns showed high antibacterial property against Gram-positive (Escherichia) and Gram-negative (Staphylococcus aureus) bacteria.
