Abstract: An amorphous metal laminate sheet having an excellent electromagnetic wave-shielding effect including a core layer containing at least one amorphous metal sheet layer which may be plated with an electroconductive metal, at least one flexible polymeric coating layer laminated on at least one surface of the amorphous metal-coating core layer, and optionally, at least one reinforcing fibrous fabric layer.

Abstract: A stainproof, flame-resistant composite sheet material including at least one silicone polymer layer containing a silicon resin or rubber and optionally a flame-resistant inorganic filler and at least one stainproof surface layer containing at least one synthetic thermoplastic stain-resistant, weathering-resistant polymeric material, the silicone polymer layer and the stainproof surface layer being bonded optionally through an adhesive material, a cold plasma or corona discharge-modified surface portion of the silicone polymer layer or a cold plasma or corona discharge-modified and graft polymerization-modified surface portion of the silicone polymer layer.

Abstract: Disclosed is a process for preparing a water-proof sheet by forming a polymer coating on both the surfaces of a fibrous substrate fabric. At first, the fibrous substrate fabric is treated with a water repellant, and both the surfaces are subjected to the low temperature plasma treatment or corona discharge treatment. Then, a polymer coating is formed on both the surfaces. According to this process, the peel strength of the polymer coating is improved and the water absorbing property is reduced substantially to zero. If an inorganic fiber substrate fabric is treated according to this process, the bending resistance is highly improved in the resulting water-proof sheet.

Abstract: Textile fabrics are firmly lap welded to each other by superposing two end portions of one or two fabrics on each other while interposing a piece of a synthetic polymeric bonding tape between the superposed two end portions and by applying a high frequency wave treatment and/or heat treatment to the interposed portion of the bonding tape through at least one of the superposed end portions while pressing them, to melt the interposed portion of the bonding tape thereby lap welding the end portions of the fabric or fabrics to each other.

Abstract: A water-proof fabric capable of providing a fuse-bonding activity by applying a high frequency wave treatment or heating treatment thereto, which is characterized in that at least one fuse-bonding region is formed on at least one surface of the water-proof fabric by coating the surface with a polymeric fuse-bonding agent capable of providing an adhering activity when a high frequency wave treatment or heating treatment is applied thereto.

Abstract: A water-impermeable sheet material capable of preventing formation of water drops thereon, has one or two water-impermeable layers, at least one of which layers holds, on the surface thereof, a water drop-preventing agent in the form of fine solid particles and consisting of at least one hydrophilic but water-insoluble substance, at least a portion of the water drop-preventing agent being exposed to the ambient atmosphere.

Abstract: Tarpaulins having great tearing strength, which are produced by weaving base fabrics from the mixture of a principal thread and another thread being superior to the principal thread in either of breaking elongation, breaking strength and breaking work or being different from the principal thread in adhesive strength with respect to film, or from the mixture of the principal thread to be used for warp and woof and the another binding yarn being superior to the principal thread in either of breaking elongation, breaking strength and breaking work or being different from the principal thread in adhesive strength, and by forming films consisting of plastics, rubbers or mixtures thereof on the base fabrics by application or adhesion.
