Abstract: Disclosed in this specification is an aqueous dispersion for treating a textile. The dispersion generally includes surface-functionalized inorganic oxides in combination with a fluorochemical. Significantly lower concentrations of fluorochemicals are present in comparison to prior art dispersions.

Abstract: Disclosed are embodiments and methods relating to the treatment of textile, such as a textile substrate, with an aqueous dispersion of surface-functionalized particles and a fluorochemical, or a textile substrate treated with an aqueous dispersion of surface-functionalized particles, a fluorochemical, and a flame retardant chemical. Textiles treated in accordance with the disclosed embodiments (e.g., fluorine concentration of from 20 to 900 ppm) demonstrate an average burn rate less than about 4.0 inch/minute, and an average weight loss is less than about 40% of the original weight. During burning of the treated textile, flaming drips extinguish (on average) in less than about 2 seconds, or does not increase the peak heat release rate by more than about 70%, and the mass loss rate by more than about 50%.
