Abstract
Description
本発明は、吸収材料及びその製造方法に関する。
本発明への背景の以下の解説は、本発明の理解を容易にすることが企図される。しかしながら、該解説は、言及されている材料のいずれも、本出願の優先日時点で任意の管轄において、公開されていた、公知であった又は通常の一般知識の一部であったという承認又は了解ではないことを、認識すべきである。
本発明の一態様では、親水性不織布を含む第1の層と、疎水性フィルムを含み第1の層に隣接して配置されている第2の層と、を含む吸収材料であって、第1の層が、第1の流体及び第2の流体を通過させるように構成されており、第2の層が、第1の流体を通過させるように構成されており且つ第2の流体が通過するのを最小限にする又は妨げるように構成されている、吸収材料が提供される。
本発明の特定の実施形態が、これから、添付の図面を参照して説明されることになる。本明細書で使用される用語は、特定の実施形態のみを説明する目的のためであり、本発明の範囲を限定することは意図されていない。本明細書で使用される選択された用語のための他の定義は、本発明の「発明を実施するための形態」内で見出すことができ、「発明を実施するための形態」の全体にわたり当てはまる。更に、別段の定義がない限り、本明細書で使用される全ての技術的及び科学的用語は、本発明が属する分野における当業者によって通常理解されるのと同じ意味を有する。可能なところで、同じ参照数値が、明確さ及び一貫性のために図の全体にわたって使用される。
(i.)皮膚の隣にある又は皮膚に直接隣接している第1の層20の、乾燥及び快適さのための逃す効果、並びに第2の層30の疎水性通気性フィルムの、液体の漏れを最小限にする/防止するが空気に浸透性であること
(ii.)第2の層30は、第1の層20が、例えば尿、血液、水などの液体と接触することになるときに、第1の層20の断裂を最小限にすることによって吸収材料10の構造的一体性を強化する
(iii.)任意の湿気は、疎水性の第2の層30に逃されることになり、これは、マットレス等の構造物への液体の漏れを防ぐ。
