Description
他の実施形態では、吸収性衣類は、上面シート及び裏面シートを含むことができ、この一方又は両方は、部分的に縦方向に延びるフラップを形成することができる。典型的には、このようなフラップは、トラフを形成するために内側に向けられ、フラップの1つ又はそれ以上の端部を衣類に固定させて、その反転を防ぐことができる。従って、フラップは、吸収性複合材の全体的な幅には寄与しない。
本発明の別の態様では、身体滲出物から使用者を保護する方法は、使用者の身体に吸収性衣類を当てる段階を含む。
更に別の目的及び利点と共に本発明は、添付図面と併せて以下の詳細説明を参照することにより最もよく理解されるであろう。
図面に描かれた多くの特徴及び寸法、特に層の厚さなどの表示は、図解及び明瞭性を助けるために幾分誇張されている。
弾力的な延伸又は他の伸長の割合は、公式:100*(L−L0)/L0により判断することができる。ただし、L=延伸長さ、及び、L0=初期長さである。
身体パネルはまた、伸張可能材料か、又は、エラストマー性材料及び伸張可能材料の組合せで作ることができる。個々の身体パネルの各々が、異なる材料で構成することも実質的に同じ材料で構成することもできることは容易に認められるはずである。
本説明の目的では、「不織ウェブ」という用語は、繊維織り又は編み工程の助けを借りずに形成した繊維材料のウェブを意味する。「布」という用語は、全ての織り、編み、及び不織の繊維ウェブを意味するのに用いる。
裏面シート68は、液体不透過性であることが好ましいが、例えば、保持部分と共に障壁層を用いる場合には、液体透過性とすることもできる。例えば、一実施形態では、裏面シートは、薄いプラスチックフィルム、又は他の可撓性の実質的に液体不透過性材料で作ることができる。本明細書で用いる場合、「可撓性」という用語は、馴染み易く、使用者の身体の全体的な形状及び輪郭に容易に適合する材料を意味する。裏面シートは、様々な体液及び身体滲出物が、様々な寝具や使用者が吸収性衣類の上に着用した外衣を濡らしたり、又は他の方法で汚したりするのを防止する。詳細には、裏面シートは、厚さ約0.012mm〜約0.051mmのポリエチレンフィルムのようなフィルムを含むことができる。
例えば、伸張可能な裏面シートは、ネックした繊維、ちりめん繊維、マイクロプリーツ繊維、ポリマーフィルムなど,及び、その組合せで構成することができる。布は、スパンボンド布のような織又は不織材料とすることができる。適切な伸張可能材料の一例は、坪量が約1.2osyの60%ネックしたポリプロピレンスパンボンドである。
合成吸収性ゲル化材料は、典型的には、濡れるとヒドロゲルを形成するキセロゲルである。しかし、「ヒドロゲル」という用語は、一般に材料の湿潤及び非湿潤形態の両方を意味するようにも用いられている。
側縁部は、好ましくは、横幅が約3mmよりも大きく約75mmよりも小さい。更に好ましくは、各側縁部の幅は、約15mmと約45mmの間であり、更に好ましくは、約25mmと約35mmの間である。好ましくは、側縁部を組み合わせた横幅は、吸収性複合材の全横幅の少なくとも3%で約75%を超えず、更に好ましくは、全横幅の約15%と50%の間であり、更に好ましくは、約25%と35%の間である。身体パネルは、吸収性複合材の側縁部の横方向及び縦方向端を超えて延びる。
