Description
30gsmのポリエステルスパンレーススクリム(Kolon,韓国)上にナノウェブを紡糸し、これをポリエステルフェルト上にニードルパンチした。
接着剤によってナノウェブをポリエステルフェルトに結合させた。ポリウレタン接着剤を130℃でフェルトに適用した。次いで、ナノウェブを軽く押さえながら接着剤に接着させた。
接着剤によってナノウェブをポリエステルフェルトに結合させた。この積層工程は、トリクロロエチレン中のポリウレタン接着剤を室温でフェルトに適用することを含むものとした。次いで、ナノウェブを軽く押さえながら接着剤に接着させた。
ナノウェブ+フェルト+接着剤を2本のロール間のニップを通過させることにより、ナノウェブとポリエステルフェルトとを接着剤によって結合させた。線速度を0.8ヤード毎分とした。ロールの温度を180℃とした。
このナノウェブを含むフィルターを、市販の濾過媒体から作製されたフィルターと比較した。比較例である、2.5dtexのステープル繊維から作製されたポリエステルフェルト(TTL Germany、製品PES3455−3/01)、ポリエステルフェルトに積層されたePTFE膜(TTL Germany、製品PES3054−1/01 T101T)、およびPTFEポリマーでコーティングされたポリエステルフェルト(TTL Germany、製品PES3455−3/01 T95)を試験した。これらのフィルターはいずれも同程度の目付(約500gsm)および厚みを有するものとした。
次に、本発明の態様を示す。
1. フィルターバッグを被せた支持構造を備えるバグフィルターであって、前記フィルターバッグの生地が、少なくとも1つの基材層と、それと対面する関係でそこに結合された目付が約2gsmを超える第1ナノウェブ層との複合体を含むバグフィルター。
2. 前記ナノウェブが、前記フィルターバッグの上流側に配置されている上記1に記載のバグフィルター。
3. 前記フィルターをVDI 3926に付して30サイクルを経た後も、前記基材層およびナノウェブ層が結合したままである上記1に記載のバグフィルター。
4. 前記基材層の前記第1ナノウェブ層が結合された面と反対側の面に結合された第2ナノウェブ層をさらに含む上記1に記載のバグフィルター。
5. 前記第2ナノウェブ層に結合された第2基材層をさらに含む上記4に記載のバグフィルター。
6. 少なくとも1つのナノウェブ層および少なくとも1つの基材層が、加熱結合、接着剤結合、ニードルパンチ、および水流交絡からなる群から選択される方法によって結合されている上記1に記載のバグフィルター。
7. 前記基材層および前記ナノウェブ層が約40〜100穿孔/cm 2 でニードルパンチされており、前記ナノウェブ層の25%以下が穿孔される上記6に記載のバグフィルター。
8. 各基材層が、ポリエステル繊維、炭素繊維、ポリイミド繊維、ガラス繊維、およびこれらの混合物から選択される繊維を独立して含む上記1に記載のバグフィルター。
9. フィルターバッグを被せた支持構造を備えるバグフィルターであって、前記フィルターバッグの生地が、少なくとも1つの基材層にウェブが対面する関係で結合された複合体を含み、前記ウェブが、目付が約0.1gsmを超えるナノウェブ層と前記ナノウェブ層に結合されたスクリムとを含み、前記ウェブが、前記フィルターバッグの上流側に配置されているバグフィルター。
10. 前記スクリムが、前記ナノウェブと前記基材との間に配置されている上記9に記載のバグフィルター。
11. 前記ナノウェブ層が、前記スクリムと前記基材との間に配置されている上記9に記載のバグフィルター。
12. 前記フィルターをVDI 3926に付して30サイクルを経た後も、前記基材層およびナノウェブ層が結合したままである上記9に記載のバグフィルター。
