A textile formulation for treating woven fabrics formed from aramid filament yarns that results in a resistance to the unraveling, fraying, and slipping of seams typical of fabrics formed from filament yarns is disclosed. This anti-fray formulation includes colloidal silica, polyurethane dispersion, and phosphonate combined to form a chemical bath in which the woven fabric may be dipped. This formulation adds 2%-5% to the dry weight of the woven fabric, and does not impact the beneficial properties of fabrics formed from filament yarns such as structural stability or flame retardancy, but does create a fabric that is more resistant to the unraveling, fraying, and slipping of seams. A method of creating a textile formed from aramid filament yarns exposed to an anti-fray formulation including colloidal silica, polyurethane dispersion, and phosphonate that does not impact the beneficial properties of fabrics formed from filament yarns such as structural stability or flame retardancy, but does create a fabric that is more resistant to the unraveling, fraying, and slipping of seams, is also provided.
