| Zusammenfassung: | PROBLEM TO BE SOLVED: To meet the needs in the filter industry for a nanoweb plus scrim structure that retains superior filtration properties of a nanoweb layer while being pleatable with no further modification.SOLUTION: A filter media comprising a nanofiber layer and a substrate layer. The nanofiber layer comprises a polymer material and has a fiber diameter of about 0.01 to 1.0 micron, a basis weight of about 0.5 to 30 gsm, and a thickness of at least about 2 microns. The nanofiber layer further has a surface stability index of at least about 5 kN/m. The media is further pleated.
【課題】フィルター業界では、ナノウェブ層の優れた濾過性質を保持すると共に、さらに改良しなくてもプリーツ加工が可能な、スクリムにナノウェブを加えた構造を必要としている。【解決手段】ナノ繊維層と支持体層とを含む濾過媒体であって、ナノ繊維層が、ポリマー材料を含み、かつ約０．０１〜１．０ミクロンの繊維直径、約０．５〜３０ｇｓｍの坪量、および少なくとも約２ミクロンの厚さを有し、ナノ繊維層が少なくとも約５ｋＮ／ｍの表面安定性指標をさらに有し、媒体はさらにプリーツを付けられている、濾過媒体。【選択図】なし |
