Abstract: A preform material for manufacturing a protective garment having a top material, in particular a firefighter's protective garment. The material is made of an insulating lining made up of an at least two-ply water-jet-consolidated nonwoven fabric having a weight per unit area of 80 g/m2 or lighter for each individual ply, a lining material having a weight per unit area of 120 g/m2 or lighter, that is quilted to the at least two-ply nonwoven fabric; and a semipermeable membrane, constituting a moisture barrier. After the at least two-ply water-jet-consolidated nonwoven fabric has been quilted to the lining material, the semipermeable membrane is laminated onto the outer side, facing away from the lining material, of the nonwoven fabric ply and has a weight per unit area of 20 to 30 g/m2.

Abstract: A flame barrier made of nonwoven fabric for use as a component of a planar multilayer structure, especially a vehicle or aircraft passenger seat. The flame barrier contains staple fibers made of phenolic resin, para-aramid, or melamine resin, alone or mixed with 20 to 60 wt % preoxidized polyacrylonitrile staple fibers. The nonwoven fabric barrier also contains 15 to 30 wt % vermiculite, which is distributed through the entire volume of the nonwoven fabric. The flame barrier possesses a mass per unit area of 100 g/m.sup.2 to 210 g/m.sup.2. The method of manufacturing the nonwoven fabric flame barrier makes use of water jet needling.

Abstract: A thermostable substrate for flexible circuit boards having excellent flame-resistance, handling, and storage qualities may be produced by treating a substrate of a nonwoven fabric or paper with a flame-resistant, halogen-free polymeric composition. The polymeric composition comprises an aqueous mixture of a copolymerizate of acrylic acid esters and styrene, and an aminoplastic or phenoplastic precondensate to which a mixture of fine-particle red phosphorus and fine-particle ammonium polyphosphate is also added.

Abstract: Polymers, which have polyurethane and/or polyurea groups and contain finely divided fillers, are synthesized by reacting compounds, which contain at least two hydroxyl and/or amino groups, with at least difunctional isocyanates, optionally in the presence of catalysts, and mixing with suitable fillers. The compounds, containing hydroxyl and/or amino groups, and the isocyanates, are separately mixed intimately with finely divided solids so that flowable powders are obtained. The powders obtained are mixed in a stoichiometrically required amount, and the powder mixture is subjected to the action of shear forces at, if necessary, a higher temperature. The mixture of solids obtained has a shelf life of several days or weeks without reaction between the reactive compounds contained therein.

Abstract: A cable wrap which swells upon contact with water is made by coating one side of a nonwoven fabric support with a polyvinyl alcohol binding agent and then with a superabsorber powder, drying the coated fabric between contact surfaces, printing a polyacrylate binding agent plaste onto the superabsorber surface, and then drying the coated fabric. Alternatively, the cable wrap can be made by printing a polyacrylate binding agent paste onto a nonwoven fabric support, applying a polyvinyl alcohol binding agent onto the polyacrylate binding agent paste, sprinkling superabsorber powder onto the polyvinyl alcohol binding agent, and drying the coated fabric between contact surfaces.

Abstract: A method is disclsed for surface improving sheet-like substrates to impart them with a marbleized effect. A transfer sheet is pressed on the substrate at elevated temperatures. The transfer sheet is comprised of superimposed layers of synthetic resin. The resin layer closest to the backing of the transfer sheet is devoid of pigments, while the resin layer adjacent the pigment free layer comprises 2 to 40% by weight, calculated on the amount of resin, of a flake-like pigment. The pressing of the transfer sheet against the substrate is carried out with a press tool devoid of surface pattern and having a generally flat press surface.
