Abstract: A waterproof cloth comprising a base cloth made of heat-resistant fibers having a fluorine resin adhering to their surface and a film of a fluorine resin fused integrally to at least one surface of the base cloth. The waterproof cloth can be produced by laying the film on the base cloth and heating them under pressure.

Abstract: A support and a process for preparing the support are disclosed. The support includes a metal pipe having two ends, a pair of plugs and a covering tube. The plugs are positioned in each end of the metal pipe and are formed from a thermoplastic resin. The plugs each include an outer portion having an outside diameter that is equal to the outside diameter of the metal pipe. The covering tube is formed from a thermoplastic resin that is compatible with the thermoplastic resin forming the plugs. The covering tube covers and closely contacts the entire outer surface of both the metal pipe and the outer portions of the plugs.

Abstract: A knitted or woven cloth having antistatic properties which is suitable for use in the preparation of filter bags and garments, which is characterized in that said cloth contains an electrically conductive thread composed of 10 to 90 weight % of electroless metal plated staple fibers, and 90 to 10 weight % of metallic filaments, in an amount of 0.1 to 1.0 thread per cm width of the cloth.

Abstract: A process for the production of metal-plated staple fibers comprising providing staple fibers having an areal weight of 0.5 to 5.0 kg/m.sup.2, activating said fibers by conventional means, and spraying an electroless metal-plating solution onto the activated fibers at a space velocity of 100 to 600m.sup.3 of the plating solution per m.sup.3 of the fibers per hour.
