Abstract: 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.
