Description of the Related Art Recently, a large amount of an adsorptive sheet in which activated carbon is impregnated on a nonwoven fabric or a net has been used for an air purifier, an air conditioner, a deodorizer, and the like. As the adsorptive element used in these devices, a method of uniformly adhering granular activated carbon to a nonwoven fabric or urethane foam using an adhesive has conventionally been used. Activated carbon has also been thermally fused using a material made of a hot melt material as an adhesive.

た。[0003] As a method of adhering activated carbon to a nonwoven fabric, a method has been adopted in which an adhesive is applied to the nonwoven fabric, activated carbon particles are sprayed and pressed thereon, and the solvent contained in the adhesive is evaporated to dryness. Was. With this method, it is difficult to uniformly apply a high-viscosity adhesive to a soft nonwoven fabric,
When a dilute adhesive is applied by increasing the amount of the solvent to lower the viscosity, it is inevitable that the adhesive strength is reduced. It is necessary to apply a large amount of adhesive to improve the adhesiveness,
It has been pointed out that when a large amount of adhesive is used, the surface of the activated carbon particles is coated with the adhesive, and thus the adsorptivity is reduced.

上昇して、実用上困難な場合もあった。In order to avoid these obstacles, a method of hot-bonding activated carbon particles using a net made of a hot-melt adhesive has been used, but there is a drawback that the hot-melt agent alone is inferior in form stability. Therefore, it is necessary to use a heat-resistant nonwoven fabric or the like at the same time. However, since two types of sheet materials, ie, a nonwoven fabric and a hot melt material, are used, the cost increases and there are cases where it is practically difficult.

い。Means for Solving the Problems When a hot melt type adhesive is used as an adhesive when activated carbon particles are adhered to a sheet, the adsorption capacity of activated carbon is much less reduced than in a solution type or an emulsion type. . This is achieved by properly selecting the bonding temperature of the hot melt adhesive.
This is because the area of the activated carbon surface covered with the adhesive can be extremely reduced. However, it is inevitable that the fiber structure made of the hot melt adhesive is considerably deformed.

The idea is that if a polymer with a higher melting point than the sheath is used, high form stability can be maintained even when the activated carbon particles are adhered to the sheet, and the activated carbon particles are sprayed on the sheet- like fiber layer by hot air. By
It has been found that the particles can be uniformly distributed deep inside the tissue, and based on this, the present invention has been reached.

るポリマーの組合せがより好ましい。The core must use a polymer that does not soften when the activated carbon particles are bonded to the fibers. When softened, the form of the sheet- like fiber layer is distorted, and cannot be used as an adsorptive element such as an air purifier or an air conditioner. When the sheath component acts as a hot melt adhesive at a temperature near the melting point of the polymer, the melting point of the core polymer is adjusted to prevent the sheet- like fiber layer from being distorted. It is necessary to use a polymer at least 10 ° C. higher than the melting point of the polymer. A combination of polymers having a difference in melting point of 20 ° C. or more is more preferable.

る。Activated carbon is usually made of charcoal or coal such as coconut shell or wood, and activated carbon is activated at a high temperature with steam or carbon dioxide gas. Alternatively, it may be made by treating with zinc chloride, phosphoric acid, concentrated sulfuric acid or the like. Although the properties of the activated carbon obtained by the raw materials or production methods are somewhat different, activated carbons produced by any raw materials and methods can be used in the present invention. Activated carbon has many shapes such as crushed carbon, granulated carbon, granular carbon or activated carbon fiber, activated carbon felt, activated carbon fabric, activated carbon sheet, etc., depending on the purpose of use, and any form of activated carbon can be used in the present invention. .

Activated carbon particles from the top together with hot air at a temperature about 10 ° C or more higher than the softening point of the polymer in the sheath
Activity permeated into tissues such as nonwoven fabric by spraying
Charcoal particles can be fixed. At the same time, it is preferable to suction the hot air to the lower side of the wire mesh. If the hot air is not sucked, there is a problem that the blown hot air spreads in all directions and the activated carbon is scattered. Also, it is desirable that the hot air forms a circulation system, and if the amount of heat reduced by the temperature difference during the circulation is replenished, the circulation system can always be maintained at a constant temperature, and activated carbon particles leaking from the sheet- like fiber layer can be removed. When the sheet passes through the sheet again, it can be captured and adhered to the sheet, and loss of the activated carbon can be prevented.

In such a case , if a venturi tube is provided in the hot air circulation system and a certain amount of activated carbon particles are introduced into the system, the activated carbon particles are continuously sprayed onto the fibers inside the sheet while spraying the particles.
It can be adhered to. Alternatively , after the introduction of the activated carbon particles is completed, by circulating only hot air for a certain period of time, the activated carbon particles are more firmly adhered to the inside of the sheet fiber layer.
