【発明の詳細な説明】
本発明は、経時劣化の極めて小さい静電気式空気ろ過フ
ィルタに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrostatic air filtration filter that exhibits extremely little deterioration over time.
従来のこの種のフィルタは、羊毛または合成繊維の不織
布に特殊な樹脂を含浸または添着せしめ、繊維と樹脂と
の表面接触によって配向分極させるものであった。Conventional filters of this kind have been made by impregnating or adhering a special resin to a nonwoven fabric made of wool or synthetic fibers, and polarizing the fibers by surface contact between the fibers and the resin.
このように構成された従来のフィルタは、繊維に付着し
た樹脂が常に露出された状態にあるため、周囲の気相の
条件、例えば湿度等によって自然放電が起こり、即ち、
経時劣化が大きく、また、捕集した粉塵を落とす際に樹
脂が脱落して静電気量が減少し、フィルタとしての性能
が低下するという欠点があった。In conventional filters configured in this way, the resin attached to the fibers is always exposed, so spontaneous discharge occurs depending on the surrounding gas phase conditions, such as humidity, etc.
It has the disadvantage that it deteriorates significantly over time, and when the collected dust is removed, the resin falls off, reducing the amount of static electricity and reducing the performance as a filter.
さらに、フィルタに付与される静電気量は、樹脂添着の
際の樹脂濃度や乾燥速度等の複雑な要因によって決定さ
れるため、その制御が非常に困難であった。Furthermore, since the amount of static electricity applied to the filter is determined by complex factors such as resin concentration and drying speed during resin impregnation, it has been extremely difficult to control it.
本発明は、上記従来例の欠点を解消したもので、フィル

フィルタを提供するものである。The present invention eliminates the drawbacks of the conventional examples described above.
An object of the present invention is to provide an electrostatic air filtration filter that exhibits extremely little deterioration over time, in which one or more components of various natural waxes or styrene resins that are oriented and polarized and form permanent dipoles are almost uniformly dispersed.
以下、実施例を詳細に説明する。まず、ポリプロピレン
（以下、ＰＰと略称する）の原料に、各種天然ワックス
ま７こはスチレン系樹脂の一種または数種を適当量混入
し、これら添加物を均一に分散させた後、繊維またはフ
ィルムに成形する。Examples will be described in detail below. First, the raw material of polypropylene (hereinafter abbreviated as PP) is mixed with an appropriate amount of various natural waxes or styrene resins, and after uniformly dispersing these additives, fibers or films are prepared. Form into.
フィルムの場合は、これを裁断して繊維状にする。In the case of film, it is cut into fibers.
これらＰＰの繊維は、不織布に成形されるが、その成形

散する天然ワックスまたはスチレン系樹脂を配向分極さ
せる。These PP fibers are molded into a nonwoven fabric, and mechanical force is applied before or after the molding to orient and polarize the natural wax or styrene resin dispersed in the PP fibers.
機械的力な加える方法としては、例えば、ニードルパン
チで叩くとか、先鋭な歯を有する歯車間を通す方法があ

このような処理を施すと、天然ワックス等の添加物が配
向分極を起こし、その結果、永久双極子な持ったＰＰ繊
維が得られる。When such a treatment is performed, additives such as natural wax cause orientational polarization, and as a result, PP fibers with permanent dipoles are obtained.
このＰＰ繊維からなる不織布をろ材として用い、空気ろ
過フィルタが製作される。An air filtration filter is manufactured using this nonwoven fabric made of PP fibers as a filter material.

繊維中に分散された天然ワックスまたはスチレン系樹脂
成分が永久双極子を形成しているため、周囲の気相の条
件に影響されることなく、従って経時劣化がほとんどな
く、極めて安定である。The filter according to the present invention configured as described above has PP
Since the natural wax or styrene resin component dispersed in the fiber forms permanent dipoles, it is not affected by the conditions of the surrounding gas phase, so it is extremely stable with almost no deterioration over time.
また、従来例のように樹脂が単に繊維に付着していると
いうものではないから、樹脂が脱落する心配もなく、保
守等において捕集した粉塵を落とすと静電気量が回復し
、従ってフィルタとしての集塵能力が回復する。In addition, since the resin is not simply attached to the fibers as in the conventional case, there is no need to worry about the resin falling off, and when dust collected during maintenance etc. is removed, the amount of static electricity is restored, so it can be used as a filter. Dust collection ability is restored.
このことから繰り返し使用が可能である。Because of this, it can be used repeatedly.

電気量な与え、強力な集塵能力を備えた空気ろ過フィル
タを提供することができる等の利点がある。The amount of static electricity imparted to the filter depends on the amount of various natural waxes or styrene resins mixed into the PP fibers, and
To provide an air filtration filter that can be controlled by adjusting the mechanical force applied to the fibers, and therefore has a higher electrostatic charge and stronger dust collection ability than conventional filters. There are advantages such as being able to
