A mesh cloth, which does not bring about clogging and has uniform openings throughout the whole surface, and a screen-formed plated article, which can be stably used as a printing screen and a cylinder for rotary printing, and is useful as an electromagnetic wave shielding material and a shadow mask. The mesh cloth is produced by using a core-sheath composite filament using a sheath comprising a component having a lower melting point than a core. A metal plating is applied on the mesh cloth, in which the core threads of the crossing threads at the point of intersection of the crossing threads are adhered to each other by melting the sheath component, the surface thereof is uniformly covered with the sheath component of the crossing threads, and the thickness of the cloth at the point of intersection is from 85 to 60% of the total thickness of the diameters of the crossing threads.

A damper for a loud speaker is produced by molding a substrate into a desired shape in which a fabric or knitted cloth composed of core-sheath type conjugate fibers composed of filaments having a core-sheath type structure is used as the substrate. A resin used for forming a core material in the core-sheath type structure functions as a matrix of the substrate. A sheath material having a lower melting point than that of the core material functions as an excipient, and is fused by a heat treatment and then solidified during the molding process, so as to bond together the intersections of fibers constituting the substrate and to cover the surface of the fibers. Thus, only a simple substrate production process is required and a damper for a loud speaker having excellent moldability, water-proofness, and durability is obtained.
