This paper discusses the wash fastness of dyed fabrics treated with silica sols prepared from different precursors. According to the results obtained, as a fixing agent, a sol from an epoxy‐containing precursor exhibited the best results on dyed cotton. The most suitable precursors for silk and nylon 6 were found to be amide‐ and vinyl‐containing sols, respectively. The possible fixing mechanism of the sol–gel process was also investigated. It is concluded that a gel made from sol, consisting of a thin layer with nanoparticles and nanopores can, by interaction of hydrogen bonding, Van der Waals forces and covalent bonding, fix dyes through caging and hydrogen bonding.
