ような材料を含む吸収性物品(Absorbent Foam Materials For Aqueous Body Fluids and Absorbent Articles Containing Such Materials)」という名称の米国特許第5,260,345号、1995年2月7日にダイヤー(Dyer)らに対して発行された「水性体液用の湿潤まで薄い吸収性発泡材料及びその材料を製造するプロセス(Thin-Until-Wet Absorbent Foam Materials For Aqueous Body Fluids And Process For Making Same)」という名称の米国特許第5,387,207号、1995年3月14日にラボン(LaVon)らに対して発行された「発泡性吸収材料からなる水性体液用スリット付き吸収性部材(Slitted Absorbent Members For Aqueous Body Fluids Formed Of Expandable Absorbent Materials)」という名称の米国特許第5,397,316号、及び1997年7月22日にデマレーズ(DesMarais)らに対して発行された「非常に高い水対油比を有する高不連続相エマルジョンから製造された水性流体用の吸収性発泡材料(Absorbent Foam Materials For Aqueous Fluids Made From high Internal Phase Emulsions Having Very High Water-To-Oil Ratios)」という名称の米国特許第5,625,222号である。これら特許のそれぞれを参考として本明細書に組み込む。
(試料準備)
以下に記載する試験に使用する試料は、幅1インチ×長さ4インチ(幅2.5cm×長さ10cm)であり、試料の長軸は、試料の最大の延伸性方向に対して平行に切断されている。試料は、正確に1インチ(2.5cm)幅の試料を切断するように設計された鋭利な精密(exacto)ナイフ又はある好適な鋭利な切断具を使って切断されるべきである。(材料の延伸性方向が2つ以上ある場合、試料は、代表的な伸長方向に対して平行に取るべきである。)試料は、変形領域の全パターンの対称を表す区域が表されるように切断されるべきである。(変形部分の大きさ又は第一領域及び第二領域の相対的な幾何学的形状における変化により)本明細書で示唆されるよりも大きく又は小さく切断しなければならない場合もある。この場合、試料の大きさ及び変形領域のどの区域から試料を取ったのかを(報告済みのデータと共に)書き記すこと、及び好ましくは試料に使用する代表的な区域の概略図を含めることが非常に重要である。所定の材料の3つの試料を試験する。
ヒステリシス試験は、接合されたトップシート24及びバックシート26の延伸性部分42のパーセント歪み及びパーセント力緩和を測定するために使用される。ノースカリフォルニア27709、リサーチ・トライアングルパーク(Research Triangle Park,N.C.27709)のシンテック社(Sintech,Inc.)から入手可能なTestWorks(登録商標)ソフトウェアを用いて、サウスダコタ57049、N.スーシティ(N.Sioux City,S.Dak.57049)のゲートウェイ2000(Gateway 2000)から入手可能なGateway2000 486/33Hzコンピュータにインターフェイスされるマサチューセッツ州カントン(Canton,Mass.)のインストロン社(Instron Corporation)から入手可能なインストロンモデル(Instron Model)1122で複数の試験を行なう。試験に必要な全ての必須パラメータは、各試験ごとにTestWorks(登録商標)ソフトウェアに入力する(即ち、クロスヘッドスピード、最大パーセント伸長点及び保持時間)。また、全てのデータ収集、データ分析及びグラフ化は、TestWorks(登録商標)ソフトウェアを用いて行なう。
引張り試験は、サイドパネル材料の延伸力(力)対パーセント伸長特性及びパーセント可能伸張を測定するのに使用される。ノースカリフォルニア、リサーチ・トライアングルパーク(Research Triangle Park,N.C.)のシンテック社(Sintech,Inc.)から入手可能なTestWorks(登録商標)ソフトウェアを用いて、サウスダコタ、N.スーシティ(N.Sioux City,S.Dak.)のゲートウェイ2000(Gateway 2000)から入手可能なGateway2000 486/33Hzコンピュータにインターフェイスされるマサチューセッツ州カントン(Canton,Mass.)のインストロン社(Instron Corporation)から入手可能なインストロンモデル(Instron Model)1122で複数の試験を行なう。試験に必要な全ての必須パラメータは、各試験ごとにTestWorks(登録商標)ソフトウェアに入力する。また、全てのデータ収集、データ分析及びグラフ化は、TestWorks(登録商標)ソフトウェアを用いて行なう。
