In this research work, a light and perspiration stability enhancer for the reactive azo‐dyes based on amino silicon oil (ASO) containing zinc oxide nanoparticles (ZnO‐NPs) was fabricated. The fabricated samples were characterised by Fourier transform infrared spectroscopy, and the microstructural morphologies of cotton fabrics were observed by scanning electron microscopy. The light and perspiration stability was represented by the colour difference value (Δ E CMC ), and the light stability was calculated by the ultraviolet protection factor (UPF) value. The experimental results indicated that the ZnO‐NPs dramatically improved the light and perspiration stability of all the reactive azo‐dyes; the size of ZnO‐NPs was decreased by the addition of the coupling reagent, [ γ ‐(2,3‐epoxypropoxy)propyl] trimethoxysilane (KH‐560), resulting in the significant improvement of the light and perspiration stability. However, the ASO accelerated the yellowing of reactive azo‐dyes due to its easy oxidation of activated hydrogen atoms, especially under high temperature. Further study disclosed that the fluoride‐ASO with less activated hydrogen atoms significantly improved the light stability.
