Description
従来の異形押出装置を使用して、一側面上にレール様突出部を有するテクスチャー流体透過性支持シートを製造した。ポリプロピレン/ポリエチレン衝撃コポリマー(7C06、1.5MFI、ミシガン州、ミッドランド(Midland,MI)のダウ ケミカル コーポレイション(Dow Chemical Corp.))およびポリオレフィンエラストマー エンゲージ(ENGAGE)8100(デラウェア州、ウィルミントン(Wilmington,DE)のデュポン ダウ エラストマーズ(Dupont Dow Elastomers))を共押出して、突出部の最上部表面(先端)が低融点熱シール性エラストマーを含有する、レール様突出部を有するフラットベース層を有する流体不透過性支持シートを形成した。
実施例1の方法を使用して、支持シートの一側面で突出部を有する第1の流体不透過性支持シートを押出し、そしてロールに巻いた。第1のシートをポータブル巻き戻しステーションから解き、そしてダイリップ出口より約1センチメートル下を平滑な裏側が通過するようにローラーの周りに供給した。実施例1の方法を使用して、支持シートの一側面で突出部を有する第2の流体不透過性支持シートを第1の支持シートの平滑裏側上に押出した。得られた二重層支持シートは両側面でレール様突出部を有し、これは、約305ミクロン(0.012インチ)のベース層厚さ、約965ミクロン(0.036インチ)のレール高さ、および約356ミクロン(0.014インチ)のレール厚さ、ならびに約991ミクロン(0.039インチ)レール中心間の間隔を有した。二重側面支持シートは、ベース層の両側面のレール先端で厚さ約127ミクロン(0.005インチ)のエンゲージ(ENGAGE)8100樹脂層を有した。
国際公開第9929220号パンフレットの実施例1に記載されるものと同様に、ポリプロピレンの熱的誘導された相分離微多孔性膜に実施例2の二重側面流体不透過性支持シートを熱的に積層化した。膜は、約76ミクロン(0.003インチ)の厚さ、約0.21ミクロンのバブルポイント細孔径および約35%の油含量を有した。
従来の異形押出装置を使用して、両側面上にレール様突出部を有するテクスチャー流体不透過性支持シートを製造した。ポリプロピレン/ポリエチレン衝撃コポリマー(C104、1.5MFI、ミシガン州、ミッドランド(Midland,MI)のダウ ケミカル コーポレイション(Dow Chemical Corp.))およびポリオレフィンエラストマー、エンゲージ(ENGAGE)8100(デラウェア州、ウィルミントン(Wilmington,DE)のデュポン ダウ エラストマーズ(Dupont Dow Elastomers))を共押出して、突出部の最上部表面(先端)が低融点熱シール性エラストマーを含有する、レール様突出部を有するフラットベース層を有する流体不透過性支持シートを形成した。
上記実施例3の手順を使用して、国際公開第9929220号パンフレットの実施例1に記載されるものと同様に、ポリプロピレンの熱的誘導された相分離微多孔性膜に実施例4の二重側面流体不透過性支持シートを熱的に積層化した。微多孔性膜は、約58.75質量%のポリプロピレン樹脂(5D45、コネチカット州、ダンバリー(Danbury,CT)のユニオン カーバイド コーポレイション(Union Carbide Corp.))、35.0質量%の鉱油(ホワイト ミネラル オイル(White Mineral Oil)#31 USPグレード、アモコ オイル カンパニー(Amoco Oil Company))、25質量%のグリーン#7顔料を含有する4.0質量%のグリーン顔料濃縮物(名10066064 FDA グリーン、ポリワン カンパニー(PolyOne Company))および2.25質量%のフルオロカーボンエステル(3Mカンパニー(3M Company)製、2002年5月29日出願の米国特許出願第10/159,752号明細書、第27頁および第28頁にクエン酸エステルFC425として記載の通り製造されたもの)を含んでなる。要約すると、トルエン、C4F9SO2N(CH3)CH2CH2OH(MeFBSE)、クエン酸、p−トルエンスルホン酸およびポリエチレンアルコール(テキサス州、シュガーランド(Sugar Land,Texas)のベーカー ペトロライト コーポレイション(Baker Petrolite Corp.)からユニリン(Unilin)−425 105−OH当量として得られたもの)を一緒に混合した。混合物を還流下で15時間加熱した。ディーンスターク(Dean Stark)トラップ(反応フラスコに装備されたもの)に所望量の水が回収された時、トルエンが蒸留除去された。ほとんどのトルエンが蒸留除去された時、溶融生成物をパンの中に注ぎ入れ、そして120℃のオーブン中で4時間乾燥させた。
上記実施例3の手順を使用して、国際公開第9929220号パンフレットの実施例7〜9に記載されるものと同様に、ポリプロピレンの熱的誘導された相分離微多孔性膜に実施例4の二重側面流体不透過性支持シートを熱的に積層化した。膜を親水性にするために、溶融混合物に1.5重量%のソルビタンモノラウリレート(スパン(SPAN)−20、ニュージャージー州、イルビントン(Irvington,NJ)のラガー ケミカル カンパニー インコーポレイテッド(Ruger Chemical Co.,Inc.))を添加した。得られた膜モジュールエレメントは、多層支持シートの両側面で微多孔性膜を含んでなり、微多孔性膜は親水性および水分透過性であった。
