Assembly of mattress making or furniture capitonne, containing sulphur, as additive inhibiting the slow combustion flame and without

摘要

Disclosed is a smolder resistant upholstered furniture or mattress assembly and a method for rendering the composite materials of such assembly smolder resistant. Placement of a layer of sulphur immediately adjacent a normally smolder-prone material in the composite effectively prohibits the advance of smoldering combustion to a dangerous stage. The sulphur layer is advantageously applied by backcoating the fabric overlay, coating or impregnating the fibrous or polyurethane foam materials or separating layers of such materials with sulphurcontaining films, fabrics and the like. An advantage usly effective amount of sulphur is from about 25-50 g/m2 to about 250-300 g/m2 in a layer having a depth of about 1 to 3 mm.
