また、請求項8記載のフィルタ素子は請求項6に記載のフィルタ素子において、折り畳まれた前記フィルタろ材にコルゲート加工を施したものである。
本発明のフィルタろ材の製造方法は、請求項9に記載の通り、第1の通気性基材の表面に吸着材と熱接着剤とを散布、堆積し吸着層を形成する工程と、前記吸着層の上方から前記第1の通気性基材の幅方向に沿って筋付けする工程と、前記第1の通気性基材を前記吸着材を挟み込むように第2の通気性基材で被覆する工程と、積層された前記第1および第2の通気性基材を熱プレスし前記熱接着剤を硬化させる工程と、を備えるものである。
フィルタ素子のフィルタろ材は、折り畳まれた折り込み空間に空間維持部材が挟み込まれていてもよい。空間維持部材は、フィルタろ材の有効ろ過面積を確保するために設けられるものである。空間維持部材は、例えば、波型に形成されたアルミニウムや樹脂製のセパレータや櫛歯状のスタビライザや、フィルタろ材の裏表面にプリーツ(折筋方向)と直行して付着された樹脂ビードなどである。
あるいは、フィルタ素子のフィルタろ材は、空間維持部材を用いず、筋付けされたろ材に波状にコルゲート加工をすることも可能である。この場合、空間維持部材を使用しないため、安価にフィルタを製造することが可能となるとともに、波状にろ材が加工されるため、枠体に入るろ材が増え、高寿命、低圧損のフィルタができる。コルゲート加工は、一般に、一対の歯車の間にろ材を通して波状に賦形され、その波状の高さは使用するギアのモジュールで制御でき、平歯車やヘリカル歯車等がある。
以下の実施例においては、フィルタろ材の目付、厚み、通気度などの物性は、JIS L1096「一般織物試験方法」記載の方法により測定した。
このように、本実施例のフィルタ素子は、空間維持部材を用いず、筋付けされたろ材に波状にコルゲート加工を施してフィルタ素子とすることも可能であることが確認できた。
