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.
A fabric formulation comprised of an effective amount of silica, an effective amount of polyurethane, and an effective amount of phosphonate, wherein the formulation defines a weight and is administered to a fabric to reduce incidence of fraying, unraveling, or slipping at one or more fabric seams.
A method of forming a textile formed from filament yarns that is resistant to fraying, unraveling, and slipping at one or more seams, the method comprising,
