ものとなる。Packaged materials such as chemical exothermic agents, desiccants, gas adsorbents, and enzymes (including immobilized enzymes, hereinafter the same) are packaged in air-permeable packaging materials, such as heating equipment and various other products. It is well known that it is used for many purposes. With such packages, the powder and granules move during use and become unevenly distributed in clusters or clusters, which can cause problems during use, such as uneven heat generation and an unpleasant feeling of use. was there. Many efforts have been made to compensate for these shortcomings. That is, for example, the method of dividing powder into small cells by quilting etc., the empty Fi of the thread mass! There is a method (2) in which the filament is filled with the filament, and a method Q) in which the filament is attached to the surface of the filament and then made into a felt shape. However, even if it is divided into small cells as shown in (■), the small cells cannot be made that small, so uneven distribution and agglomeration due to the movement of powder and granules within the small cells are essentially unavoidable. Q+ is expensive and has an extremely small amount of filling, while ■ has a small amount of adhesion, low porosity, and lacks elasticity.

填シートの製造法。[Claims] 1. Nonwoven fabrics are attached to both surfaces of a three-dimensional continuous porous sheet whose pores are filled with powder or granular material using a heat-melting network adhesive, and the three-dimensional continuous A filled sheet that is sealed so that the pores of the porous sheet are substantially eliminated. 2. Paste non-woven λ11 type on one surface of the three-dimensional continuous pore sheet with a heat-melting network adhesive, and apply the three-dimensional continuous pore sheet from the pore openings on the other side of the three-dimensional continuous pore sheet. The pores other than the periphery of the three-dimensional (3-dimensional) imperial porous material sheet are filled with powder and granular material, and then non-woven fabric is attached to the surface using a heat-melting network adhesive, and the pores in the periphery of the three-dimensional) imperial porous material sheet are substantially filled. A method for manufacturing a filled sheet, characterized in that the peripheral portion is sealed by causing the filling sheet to disappear.
