Abstract
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。
