ABSTRACT:
A tailorable, flame barrier, puncture-resistant composite fabric sheet material suitable for use for example as an upholstery cover over a urethane or other foam seat cushion and the method of producing the fabric sheet material. The fabric sheet material comprises a thermoplastic polymer layer, such as a vinyl layer, optionally top coated with an abrasion-resistant layer and which thermoplastic layer is bonded to a fibrous, non-woven layer which layer has been needle punched through a metal foil material to fragment and distribute the metal foil material and a knitted, woven sheet material. The method includes needle punching a synthetic fibrous sheet material through adjacent layers of a metal foil material, such as aluminum, and a woven, fibrous sheet, such as a knitted polyester material, and extruding a molten vinyl film onto the fibers of the non-woven layer and optionally topcoating the vinyl film to provide a composite sheet material having high flame and puncture resistance.
