    Abstract: A nonwoven which comprises fibers or filaments consolidated with a binder and which is suitable for use as a carrier web in roofing sheets which are resistant to jump fire and radiant heat is obtained by applying, together with the binder, solid particles which are resistant to heat and fire and whose spatial extension in at least one dimension is large compared with the effective hole size of the web layer. This size ratio ensures that the solid particles form a layer on the web which becomes firmly bonded to the fiber or filament web.

    Abstract: Disclosed is a tubular casing comprising a fiber-reinforced regenerated cellulose wherein the fiber-reinforcement comprises a fiber web comprising first and second edge regions, parallel to the longitudinal axis, which are overlapped and bonded to form a tube; an impregnation layer of a thermoplastic synthetic resin applied on the entire inwardly-facing surface of the fiber-reinforcement and present in a weight per unit area of less than about 50 g/m2, the impregnation layer comprising the bond for the edge regions; and a regenerated cellulose surface on the outer surface of the fiber-reinforcement. Also disclosed is a process for manufacturing the tubular casing.
