Description
本発明によれば、吸収性物品は、液体透過性トップシートを含み得る。本明細書に用いるのに好適なトップシートは、織布、不織布、及び/又は液体透過性開口を含む液体不透過性高分子フィルムの三次元ウェブを含み得る。図1において、トップシートは、参照番号30で示されている。例えば、着用者に面する面から吸収性構造に向かう液体の移送を容易にするために設けられた開口を有するフィルム材によって、着用者に面し、接触する面を提供することができる。かかる液体透過性の有孔フィルムは、当該技術分野において周知である。それらは、弾力的な三次元繊維様構造を提供する。かかるフィルムは、例えば、米国特許第3,929,135号、同第4,151,240号、同第4,319,868号、同第4,324,426号、同第4,343,314号、同第4,591,523号、同第4,609,518号、同第4,629,643号、同第4,695,422号又はPCT国際公開特許第96/00548号に詳細に開示されている。
本発明の実施形態において、吸収性コア28は、基板層100、吸収ポリマー材料110、及び典型的にはホットメルト接着剤の繊維層である熱可塑性材料120の層を備える。基板層100は、下記に詳述されるように、典型的には不織布材料から成る。
本発明によるコアを含む吸収性物品は、バックシート40を含むこともできる。バックシートは主に、吸収性構造に吸収され及び収容されている滲出物が、パンツ、ズボン、パジャマ、下着、及びシャツ又はジャケットなどの吸収性物品と接触する材料を濡らすのを防ぎ、これにより、流体移動に対するバリアとして作用しなければならない。本発明の実施形態によるバックシートは、少なくとも水蒸気の移動、又は水蒸気と空気通過の両方をさせることもでき、したがって、物品内に空気を、物品外に水蒸気を循環させることができる。バックシートは、典型的には、吸収性構造全体にわたって延在することが可能であり、存在するならば、サイドフラップ、サイドラッピング要素又はウィングの一部又は全体の中まで延在してこれらを形成できる。
人工月経流体(Artificial Menstrual Fluid)は、ヒツジの変性血液を基本にしており、これは、粘度、導電性、面張力、及び外観の点でヒトの月経液に確実に酷似するように、変性されたものである。それは、参照される米国特許第6,417,424号(プロクター・アンド・ギャンブル社(The Procter & Gamble Company)に譲渡)の第17段33行から第18段45行に説明されるとおりに調製される。
