PURPOSE:To provide a molded mask neither caught nor butted by the skin by scattering active carbon on a bulky unwoven cloth containing thermoadhesive fibers, laminating a surface layer material including thermoplastic fibers on the unwoven cloth for molding, next putting the molding between a supersonic horn and an edge-like metal mold to seal and fuse off the molding by the supersonic wave. CONSTITUTION:Active carbon is scattered on a bulky unwoven cloth including thermoadhesive fibers and then heated to fusion-weld the thermoadhesive fibers and fix the active carbon to the bulky unwoven cloth. A surface layer material including thermoplastic fibers is laminated on the unwoven cloth for molding. Next, the molding is put between a supersonic horn and edge-like metal mold to be sealed and fused off by supersonic waves. Then, the active carbon 14 is widely dispersed between the constitutional fibers of the unwoven cloth 13. Similarly, the thermoadhesive fibers adjacent to the active carbon 14 are dispersed between the constitutional fibers of the unwoven cloth 13. Thus, by heating the unwoven cloth and fusion-welding the thermoadhesive fibers, the active carbon 14 is fixed by the fusion welding of the thermoadhesive fibers dispersed adjacent to the active carbon 14, so that a molded mask with a good feeling of wearing can be provided. |
