損しやすいものであった。As a filter having such a deodorizing performance, Japanese Patent Laid-Open No. 4-200718 and Japanese Utility Model Application Laid-Open No. 52-56.
Japanese Patent No. 037 discloses a net in which a granular deodorant is adhered. However, since these filters use a net as a base material to which the granular deodorant is adhered, only a small amount of the granular deodorant can be adhered and the deodorizing performance is poor. Therefore, if you try to adhere a lot of granular deodorant, the granular deodorant is likely to fall off, and if you increase the amount of adhesive to prevent this dropping, the deodorizing performance of the granular deodorant will decrease due to the adhesive, Since it was rigid, it was easily damaged.

However, when the apparent density of the non-woven fabric of these filters is small, the same problem as that of the net occurs, and the non-woven fabric having a large apparent density has a large pressure loss.
There was a problem that the pressure loss was further increased.

優れた脱臭フィルタである。The deodorizing filter of the present invention comprises fibers having an average fiber diameter of 20 to 35 μm, which are constituent fibers in a non-woven fabric substrate having a fiber basis weight of 20 to 60 g / m 2 .
And a non-woven fabric substrate constituent fiber and a granular deodorant having a weight of 60 to 150 g / m 2 fixed by an adhesive of 30 to 130% by weight to the granular deodorant.

ある。[Function] The non-woven fabric substrate of the deodorizing filter of the present invention (hereinafter,
As the fibers constituting the “base material”), fibers having an average fiber diameter of 20 to 35 μm are used. When the average fiber diameter is less than 20 μm, the number of fibers in the base material having a unit fiber areal weight increases, so that the pressure loss becomes large, while when the average fiber diameter exceeds 35 μm, the number of fibers in the base material having a unit fiber weight is This is because the strength of the base material is reduced because the amount of the base material decreases. More preferably, it is 25 to 30 μm.
【０００９】なお、基材を構成する繊維の断面形状は円

などの多角形、Ｙ形やＸ形などの、いわゆる異形断面形
状の繊維であっても構わない。このような異形断面形状
の繊維の場合には、次の式により円形断面に換算した値
を繊維径とみなす。The cross-sectional shape of the fibers constituting the substrate need not be circular, but may be oval, oval, polygonal such as triangle or hexagon, Y-shaped or X-shaped so-called irregular cross-sectional shape. It may be fiber. In the case of a fiber having such an irregular cross-sectional shape, the value converted into a circular cross section by the following formula is regarded as the fiber diameter.
【００１０】 繊維径（μm）＝１１.８９×（ｄ／ρ）0.5 ｄ：繊度（デニール）、ρ：比重Fiber diameter (μm) = 11.89 × (d / ρ) 0.5 d: fineness (denier), ρ: specific gravity
【００１１】また、平均繊維径は繊維の重量比率によっ

０重量％と、繊維径１０μmの繊維３０重量％とからな
る場合には、平均繊維径は２４（μm）（＝３０×０.７
＋１０×０.３）となる。The average fiber diameter means a value averaged by the weight ratio of the fibers. For example, a fiber 7 with a fiber diameter of 30 μm
When it is composed of 0% by weight and 30% by weight of a fiber having a fiber diameter of 10 μm, the average fiber diameter is 24 (μm) (= 30 × 0.7
It becomes + 10 × 0.3).

に優れているため、好適に使用できる。The fibers constituting the base material of the deodorizing filter include, for example, polyclar fiber, vinylidene fiber, polyvinyl chloride fiber, polyester fiber, polyamide fiber, acrylic fiber, polyvinyl alcohol fiber, polypropylene fiber, polyethylene fiber, or a cross-sectional shape. Synthetic fibers such as sheath type, eccentric type, side-by-side type, sea-island type, chrysanthemum type, laminated bimetal type composite fibers, etc., and these synthetic fibers mixed with aromatic agents, antibacterial agents, antifungal agents, etc. However, it is possible to use fibers having functions such as aromaticity, antibacterial properties and antifungal properties, regenerated fibers such as rayon and viscose, semi-synthetic fibers such as acetate, and inorganic fibers such as carbon fiber and glass fiber. . Among these, polyclar fiber, vinylidene fiber, and polyvinyl chloride fiber are excellent in flame retardancy, and polyester fiber is excellent in chemical resistance and heat resistance, and thus can be suitably used.

とができる。なお、スパンボンド法により得た繊維ウエ
ブを、そのまま基材として使用しても良い。A non-woven fabric which is a base material of the deodorizing filter is formed from such fibers. This non-woven fabric is, for example, a fiber web obtained by a card method, an air-laying method, a wet method, a spunbond method or the like, entanglement treatment by a needle or water flow, or by utilizing the heat fusion property of the fiber, in whole or in part. It can be obtained by a thermal fusion treatment under a constant pressure or without a pressure, or a total or partial adhesion treatment with a binder. The fibrous web obtained by the spunbond method may be used as a base material as it is.
【００１４】このようにして得られる基材の繊維目付は

が６０g/m2を越えると、繊維本数が多くなるため、圧力
損失が大きくなるためである。より好ましくは、３０〜
５０g/m2である。The fiber basis weight of the substrate thus obtained is 20 to 60 g / m 2 . This is because when the fiber areal weight is less than 20 g / m 2 , the number of fibers is small, so that there is no substrate strength, and when the fiber areal weight exceeds 60 g / m 2 , the number of fibers is large and the pressure loss increases. . More preferably, 30-
It is 50 g / m 2 .

Fix 50 g / m 2 of granular deodorant. This granular deodorant is 6
If it is less than 0 g / m 2 , the deodorizing performance is poor, and if it exceeds 150 g / m 2 , the granular deodorant is likely to drop off. More preferably, it is 70 to 120 g / m 2 .

A single metal such as rhodium, these metal oxides, these metal chlorides, zeolite, kaolin, sepiolite, silica gel, activated carbon and the like can be used alone or in combination. Further, since these granular deodorants are fixed by an adhesive, those having a size of about 1 μm or more can be used.

が少ないため、好適に使用できる。The particulate deodorant can be fixed by, for example, an emulsion type, a solution type, a hot melt type, or a heat-adhesive component of the fibers constituting the base material. It can be suitably used because the deodorizing performance is less deteriorated.

いるため、好適に使用できる。As this emulsion type adhesive, for example, acrylic type, vinyl chloride type, ethylene-vinyl acetate copolymer type, polyvinyl acetate type, synthetic rubber type, polyurethane type, polyester type, polyamide type adhesives can be used. . Among these, vinyl chloride resins are excellent in flame retardancy and therefore can be preferably used.

着剤を使用しているにも関わらず、脱落が生じやすく、
１２０重量％を越えると、脱臭性能が低下するためであ
る。より好ましくは、４０〜７０重量％である。The amount of the adhesive for fixing the granular deodorant is preferably 30 to 120% by weight based on the granular deodorant. When the amount of the adhesive is less than 30% by weight, the adhesive is likely to come off despite using the adhesive.
This is because if it exceeds 120% by weight, the deodorizing performance is deteriorated. More preferably, it is 40 to 70% by weight.

By using 30 to 130% by weight with respect to the granular deodorant, the base-material-constituting fibers and the base-material-constituting fiber are fixed to the granular deodorant. If the amount of the adhesive is less than 30% by weight, the particulate deodorant tends to come off, the base material strength is low, and the amount is 130% by weight.
If it exceeds, the deodorizing performance is likely to be lowered and the pressure loss is increased. More preferably, 40 to 10
It is 0% by weight.

い。Although the deodorizing filter of the present invention does not drop off the granular deodorant, in order to protect it from friction during production or during use, or to prevent it from falling off more reliably, a void smaller than that of the granular deodorant is used. You may laminate the fiber sheet which has.
