問題がある。2. Description of the Related Art In recent years, interest in odors in living spaces, clothing, and daily necessities has been increasing with the improvement in the living standards of general consumers. Conventionally, various sheets for the purpose of deodorization have been proposed. Deodorizing functional agents immobilized on textiles can be classified according to their deodorizing mechanisms: (1) sensory deodorizing mechanism, (2) chemical deodorizing mechanism, (3) physical adsorption and deodorizing mechanism, (4) physical chemistry It is roughly divided into a deodorizing mechanism. (1) The sensory deodorant mechanism
An aromatic type, a masking type, a neutralizing type, and the like are known, and all use an aromatic agent such as citral, benzyl acetate, turpentine oil, or the like to make it difficult to feel a bad smell. Although this mechanism is very quick-acting, it does not eliminate the odor, some odor including the fragrance remains, and its use is limited at present. As the chemical deodorization mechanism (2), an oxidation-reduction method, an addition condensation method, and the like are known, and an acrylic acid compound, a phenol compound, a manganese sulfate L ascorbic acid compound, an imine compound, or the like is used. This mechanism utilizes a chemical reaction, in which these substances and a malodorous substance cause a chemical reaction and change or combine with an odorless substance to eliminate the malodor.
However, since acidic deodorants are effective against alkaline odors, the odors that can be deodorized by the deodorant are limited, so the daily life of "refrigerator odor" and "pet odor" There is a problem in that the complex odor has a low effect, has no immediate effect, and requires an extremely long time until the effect is developed.

なる。[0003] The physical adsorption and deodorization mechanism of (3) includes activated carbon,
A porous body such as dry clay bamboo obtained by carbonizing activated clay, ceramics, zeolite, and bamboo powder is used, and a physical adsorption mechanism on the surface of the porous body is used. These have an effect on a wide range of odors as compared with the chemical deodorizing mechanism (Japanese Utility Model Publication No. 6-34105, Japanese Unexamined Patent Publication No. Hei 6-73665).
Japanese Patent Application Laid-Open No. H11-157, and also has a very high immediate effect.
However, since the porous body is a solid particle having a shape of several tens of μm to 10 mm, it is often used in a bag having air permeability. Therefore, it has a bulky shape and is limited to applications that do not require a design such as a refrigerator and a locker in a space in daily life. In addition, the solid particles packed in the bag exist in a lump, and the particles other than the particles on the surface of the lump are inefficient because they do not have a chance to come in contact with the malodorous molecules. Is impaired.

Processing methods of coating or impregnating on paper or non-woven fabric are known, but this method has a problem that the deodorizing function is significantly reduced because the binder covers most of the surface of the physical adsorbent. is there. As a method of fixing the activated carbon to a sheet without covering the surface with a binder, a method of embossing bonding between two thermoplastic sheets with deodorizing functional particles such as activated carbon sandwiched between them has been proposed (Japanese Patent Laid-Open No. Hei 8-
No. 72194). However, in this method, the deodorizing function powder is not actually fixed to the sheet, but merely held while being sandwiched between the sheets, and is deodorized at the time of secondary processing such as cutting and sewing. There is a problem that the functional powder falls off and the processability is extremely poor, and the range of application is extremely limited.

途が限定されるという問題がある。[0005] Further, there is a method in which an adhesive resin layer is provided on one of two sheets and the deodorizing function powder is fixed between the sheets in order to minimize the surface of the deodorizing function powder with a binder resin. It has been proposed (Jpn.
issue). In this method, the amount of the deodorant functional powder is increased in order to reduce the covering area between the functional powder surface and the adhesive resin layer, or the larger the powder particle size, the more the distance between the two sheets is increased. Since the bonding area is significantly reduced, the durability of the sheet itself and the secondary workability are inferior. Conversely, if the amount of deodorant functional powder is reduced or the particle size of the powder is reduced to increase the bonding strength, the surface of the functional powder is more likely to be covered with the adhesive resin layer. In addition, since the adhesive resin layer has no air permeability, it cannot be used in fields requiring air permeability such as filter materials. In addition, some of the conventionally used air-permeable sheets use paper or perforated film.However, in applications such as immersion in water or condensation, mechanical strength such as tearing strength is used. There is a problem that the reduction is remarkable and the application is limited.

常に広くなり好ましい。In the present invention, a nonwoven fabric is used for at least one sheet, and its air permeability by the Gurley method is 2
0 second or less, preferably in the range of 0.3 to 5 seconds, the average inter-fiber distance is 1 to 100 μm, preferably 30 to 60 μm
m. If the air permeability exceeds 20 seconds, the speed at which the odorous gas passes through the sheet becomes higher than the adsorption speed of the activated carbon, and as a result, the immediate effect of the deodorizing effect is impaired. When the average fiber-to-fiber distance exceeds 100 μm, when a strong force such as rubbing is applied to the sheet, the activated carbon or the hot melt agent that has fallen from the hot melt agent may leak through the sheet. On the other hand, if it is less than 1 μm, leakage of the activated carbon or hot melt agent can be prevented, but it is difficult to reduce the air permeability to 20 seconds or less. The fibrous material used for the nonwoven fabric is not particularly limited, and the above-mentioned fibrous sheet can be used. Among them, the synthetic long-fiber nonwoven fabric by the spun bond method has high air permeability and high strength even at a low basis weight. It is expressed, and the planar deodorant can be lightened, and the range of application is very wide, which is preferable.

Those having a size of 00 μm, preferably 250 to 500 μm are used. When the particle size exceeds 1000 μm, the unevenness becomes remarkable and the appearance of the sheet is impaired.
Subsequent processing becomes extremely difficult. On the other hand, if it is less than 100 μm, the activated carbon tends to fly in the air, and it becomes extremely difficult to process it into a deodorant.

Is also good. Above all, the unsupported activated carbon powder (impregnated activated carbon) and the activated carbon powder (impregnated activated carbon) loaded with an acidic substance such as a sulfanilic acid compound, an acrylic acid compound, or polyphenol in a weight ratio (impregnated activated carbon: unimpregnated activated carbon) of 1 : 99-70: 50 is preferred because the activated carbon mixed at a ratio of 99:70:50 can provide a high deodorizing effect even on the ammonia odor which is considered to be slightly weak by non-supported activated carbon. If the mixing ratio of the acidic substance-carrying activated carbon is less than 1 by weight, the deodorizing effect on the ammonia odor is reduced with the amount of activated carbon in the present invention, and if it exceeds 70, the deodorizing performance of acidic odors such as acetic acid may be reduced. is there. A more preferred mixing ratio is from 5:95 to 50:50.

From the viewpoint of handling property and workability, such as easiness of bending of the deodorizing performance and deodorizing sheet, is preferably in the range of 10 to 150 g / m 2, more preferably in the range of 15~75g / m 2 . Examples of the hot melt agent used in the present invention include EVA type, EEA type, LDPE type, polyester type, nylon type and other powdery hot melt agents usually used for processing an adhesive interlining. The particle size of the hot melt powder is 100 to 1000 μm, preferably 2 to 1000 μm.
MI is 50 to 500 μm and indicates viscosity at the time of melting.
The value is 0.1-30, preferably 1-20. If the particle size of the hot melt agent is less than 100 μm, the hot melt agent will easily fly in the air, making it difficult to process into a deodorant. On the other hand, when the thickness exceeds 1000 μm, secondary workability is remarkably impaired, for example, needle breakage occurs at the time of sewing the sheet material.

Activated powder can be bonded to the sheet only at the point of contact between the sheet and the activated carbon powder, with almost no change in shape, and it has excellent immediate deodorizing performance and is smooth and soft in appearance. It is preferable because a deodorant can be obtained. When the MI value is less than 0.1, the fluidity at the time of melting is too small, so that the adhesion between the sheets becomes weak.
On the other hand, when the MI value exceeds 30, the molten powdery hot melt agent is sucked into the sheet-like material, causing spots such as spots on the appearance, or clinging to the activated carbon surface, resulting in markedly impairing the deodorizing performance. The amount of the powdered hot melt used is preferably 10 to 200 g / m 2 .

d, a long-fiber nonwoven fabric having a basis weight of 30 g / m 2 was obtained. The air permeability of the obtained sheet is 0.3 seconds, and the average inter-fiber distance is 47 μm.
Met. Next, activated carbon: acrylic resin aqueous solution = 3: coconut shell activated carbon powder fractionated to a particle size of 250 to 500 μm was added to an aqueous acrylic resin solution diluted at a solid content of 5%.
The resulting mixture was applied to the above-mentioned sheet (sheet A) with a comma roll coater so that the applied amount of the solid was 60 g / m 2, and dried to obtain a planar deodorant. The instant deodorizing performance of this planar deodorant was remarkably poor, and the gas residual ratio was 70% after 10 minutes. In addition, the residual gas rates of hydrogen sulfide and trimethylamine were 20% and 1%, respectively.
0%, indicating that the performance of the activated carbon was significantly impaired as compared with the examples. This is probably because the acrylic resin binder covers most of the activated carbon surface.

C., an EVA powder hot melt having a melt index of 2.5 was mixed with a rotary powder mixer at a weight ratio of 2: 1 to obtain a mixed powder of activated carbon powder and hot melt agent powder. . Next, on a Kent paper (sheet A) having a basis weight of 20 g / m 2 and an air permeability of 10 seconds, using a hot roll bonding type laminating apparatus equipped with a powder dispersing apparatus usually used for laminating paper or cloth. The powder was sprayed so that the total of activated carbon powder and hot melt agent powder became 60 g / m 2 . Further, the same Kent paper (sheet B) was overlaid and joined with a hot press roll heated to 130 ° C. to obtain a planar deodorant. Although the deodorant performance and immediate effect of this planar deodorant are high,
Due to the high rigidity of the paper, the appearance was very uneven and the smoothness was poor.
