Abstract
Abstract A textile product with enhanced flame and/or smoke retardant properties and a method of forming the same is disclosed. The textile product is comprised of a textile material and a backcoating comprised of a polymer matrix and inorganic smoke suppressant and/or flame retardant intumescent particles. The backcoating may also contain an inorganic filler that further enhances the flame retardancy and low smoke properties of the textile product. The methods of forming this textile product include mixing the smoke suppressant and/or flame retardant intumescent particles with the backcoating prior to its application to the textile material or the simultaneous spreading of the particles on the textile material with the polymer backcoating in order to form a layer of the particles directly adjacent to the textile material.
