蓄積された粉塵に対しては抗菌効果を示さない。
更に、このようなフイルターは抗菌性の持続性に
乏しく、フイルターを洗浄すると抗菌効果を失わ
れる大きな欠点を有している。 Various types of air filters have been used in the past, such as air purifying air filters that aim to prevent pathogenic infections in hospitals and other sanitary fields, and air filters that aim to prevent pathogenic infections caused by the diffusion of gas discharged from vacuum cleaners into rooms. Although the development of filters has progressed and it has become possible to remove quite fine dust, it has not yet reached the stage where it can sufficiently remove even the microscopic bacteria. An even bigger problem is that the dust accumulated on the surface of the air filter is a perfect place for bacteria to breed, and the microscopic bacteria that breed can pass through the air filter, and when the air passes through the air filter, it can be reversed. It causes air pollution. As a method to prevent the proliferation of bacteria in the dust on the surface of the filter, it has been considered to apply a disinfectant to the filter material, but this method has not been shown to be effective against the dust that is in contact with the filter. However, it has no antibacterial effect on accumulated dust that has not come into contact with the filter.
Furthermore, such filters have a major disadvantage in that their antibacterial properties do not last long, and their antibacterial effects are lost when the filters are washed.
本考案者等は上記のようなエアフイルターの問

要旨とするものである。 The inventors of the present invention completed the present invention as a result of intensive research to solve the above-mentioned problems with air filters. That is, in the present invention, 2,4,4'-trichloro2'-hydroxydiphenyl ether is
The gist of this invention is an antibacterial air filter constructed using a fiber filter material to which 0.01 to 10% OWF is fixed.

性を示すものである。 The antibacterial air filter of the present invention sublimates the slightly water-soluble disinfectant 2,4,4'-trichloro 2'-hydroxydiphenyl ether, which is fixed to the fibers constituting the filter material, albeit in a very small amount.
Not only the part that is in contact with the fiber filter material, but also the surrounding area that is not in contact with the filter material exhibits antibacterial properties.

抗菌性が付与できるものである。 Although the bactericidal agent 2,4,4'-trichloro2'-hydroxydiphenyl ether used in this invention exhibits excellent sublimation antibacterial properties, it has almost no phytotoxicity to the human body, and surprisingly, it can be used with various fibers. If the fibers are treated with an appropriate method, the disinfectant will be adsorbed and fixed on the fibers, giving them permanent antibacterial properties.

ができる。 The permanent antibacterial fibers used in this invention can be produced using, for example, an emulsion dispersion aqueous treatment solution containing the bactericidal agent 2,4,4'-trichloro2'-hydroxydiphenyl ether and a dispersant, using the pad cure method, the pad steam method, and the wet treatment method. It can be obtained by treating fibers using a heat treatment method or the like at a temperature of 50 to 150°C for a period of several tens of seconds to several tens of minutes.
この場合、繊維に恒久抗菌性を付与するための
殺菌剤の固着処理量は、繊維に対して0.01〜10％
owfの範囲が好ましく用いられる。 In this case, the fixed amount of disinfectant to impart permanent antibacterial properties to the fibers is 0.01 to 10% of the fibers.
A range of owf is preferably used.
殺菌剤の使用量が0.01％owf未満の場合には充

性分散剤が好ましく用いられる。 If the amount of disinfectant used is less than 0.01% owf, sufficient permanent antibacterial properties will not be expressed, and even if 10% owf or more is applied, no further improvement in permanent antibacterial properties will be observed. On the other hand, it is desirable to use different dispersants depending on the type of fiber to improve the adsorption and adhesion of the disinfectant to the fibers. For polyester fibers, polypropylene fibers, etc., use a nonionic dispersant or an anionic dispersant. are preferably used, and cationic dispersants are preferably used for acrylic fibers, cellulose fibers, etc.

これら分散剤の使用量は分散剤の種類によつて
異なるが、通常、殺菌剤に対してその0.5〜10倍
重量の範囲が好ましく用いられる。 The amount of these dispersants used varies depending on the type of dispersant, but is preferably used in a range of 0.5 to 10 times the weight of the disinfectant.
分散剤の使用量が少量すぎると殺菌剤の水性媒
体中への均一な乳化分散が困難となるばかりでな
く繊維への十分な恒久抗菌性の付与が困難とな
る。 If the amount of dispersant used is too small, it will not only be difficult to uniformly emulsify and disperse the fungicide in the aqueous medium, but also difficult to impart sufficient permanent antibacterial properties to the fibers.
