Description
「吸収性物品」とは、身体の排出物を吸収及び保持する装置のことを指し、より具体的には、着用者の身体に接して、又は近接して配置されることにより、身体から排出される様々な排出物を吸収及び保持する装置のことを指す。吸収性物品は、おむつ、パンツ、トレーニングパンツ、大人用失禁物品、下着、生理用ナプキンなどを包含することがある。本明細書で使用するとき、用語「体液」又は「身体排出物」には、これらに限定されるものではないが、尿、血液、膣排泄物、母乳、汗及び糞便が含まれる。本発明の好ましい吸収性物品は、おむつ、パンツ、トレーニングパンツ、及び/又は生理用ナプキンである。
図1は、本発明の特定の実施形態によるおむつ10の平面図である。おむつ10は、その平に広げられた非収縮(すなわち、弾性による収縮がない)状態で示され、おむつ10の一部は、おむつ10の下層構造をより明瞭に示すために切り取られている。着用者と接触するおむつ10の部分は、図1において観察者の方を向いている。おむつ10は一般に、シャーシ12と、シャーシ12内に配置された吸収性コア14と、を含んでもよい。
以下に本発明の代表的な吸収性コアを説明する。
超吸収性ポリマー材料は典型的には超吸収性ポリマー粒子の形態である。超吸収性ポリマー粒子は多くの形状であってもよい。「粒子」という用語は、顆粒、繊維、フレーク、球体、粉末、小板、並びに超吸収性ポリマー粒子の当業者に既知のその他の形状及び形態のことを指す。例えば、粒子は、約10μm〜約1000μm、好ましくは約100μm〜約1000μm、更により好ましくは約150μm〜約850μm、及び最も好ましくは約150μm〜約500μmの粒径を有する顆粒又はビーズの形態であり得る。別の実施形態において、超吸収性ポリマー粒子は、繊維の形状、すなわち細長い針状の超吸収性ポリマー粒子であってもよい。これらの実施形態において、超吸収性ポリマー粒子は、約1mm未満、通常は約500μm未満、好ましくは250μm未満〜50μmまでの小さい寸法(すなわち、繊維の直径)を有する。繊維の長さは、好ましくは約3mm〜約100mmである。繊維はまた、織ることのできる長いフィラメントの形態であってもよい。
ラミネート吸収性コアによって構成される第1の接着剤及び任意の第2の接着剤は、ホットメルト接着剤であるのが好ましい。特定の好ましくない実施形態では、第1の接着剤はホットメルト接着剤であるのに反して、第2の接着剤は他の種類の接着剤であり得る。ラミネート吸収性コアにおける第1の接着剤+任意の第2の接着剤の平均坪量は、ラミネート吸収性コアの表面積を基準として2g/m2〜20g/m2、又は2g/m2〜10g/m2であってもよい。ラミネート吸収性コアにおける第1の接着剤のみの平均坪量は、ラミネート吸収性コアの表面積を基準として1g/m2〜18g/m2、又は2g/m2〜15g/m2であってもよい。
ラミネート吸収性コアを作製する1つの方法は以下の工程を含む:
第1のキャリア基材及び第2のキャリア基材が提供される。第1のキャリア基材及び第2のキャリア基材のそれぞれの上に、超吸収性ポリマー材料の複数のストライプが形成される。ストライプは、隣接するストライプが間隙によって分離されるように形成される。
−第1のキャリア基材を提供する工程と、
−第1のキャリア基材上で、超吸収性ポリマー材料の複数のストライプの第1のセットを、ストライプが互いに離間されて、隣接するストライプの間に間隙を形成する、工程と、
−繊維層の形態の第1の接着剤を、超吸収性ポリマー材料のストライプを含む表面上で、第1のキャリア基材上に適用する工程と、
−第1の接着剤の繊維層上に、超吸収性ポリマー材料の複数のストライプの第2のセットを形成する工程であって、超吸収性ポリマー材料の複数のストライプの第2のセットは、互いに離間されて、隣接するストライプの間で間隙を形成する、工程と、
−超吸収性ポリマー材料のストライプの第2のセット上に第2のキャリア基材を適用する工程と、を含む。
ラミネート層のそれぞれにおける超吸収性ポリマー材料のストライプの数は、3〜8、又は4〜6であってもよい。
ラミネート吸収性コア内の超吸収性ポリマー材料が液体吸収時に膨張し、拡大するときに発生する、ラミネート吸収性コアの全体的な拡大につながる力を密接にシミュレーションするために、ラミネート吸収性コアは以下で詳細に説明されているように、ラミネート圧縮伸長試験を受ける。
ドイツで2011年5月に市販されているPampers「Active Fit」おむつ、サイズ4。
ドイツで2011年5月に市販されているPampers「Baby Dry(ベイビードライ)」おむつ、サイズ4。(注記:おむつの吸収性コアは、エアフェルトと混合された超吸収性ポリマー粒子を有するエアフェルトを含む)
実施例1は、第1の下側ラミネート層及び第2の上側ラミネート層の2つのラミネート層を有するラミネート吸収性コアである。
ポリプロピレンで作製され、坪量10g/m2を有する、長さ390mm及び幅165mmの不織布ウェブ(SMS、すなわちスパンボンド−メルトブローン−スパンボンド層)が第2の上側キャリア基材として使用された。第2の接着剤(ホットメルト接着剤)の5つのストライプが、長手方向に適用され、各ストライプは幅2mmを有し、390mmの製品の長さ全体を被覆している。2つの隣接する第2の接着ストライプの中心部間の距離(ストライプの長さと呼ばれる)は、20mmだった。各ストライプの第2の接着剤の坪量は116g/m2だった。第2の接着剤は、比較実施例1の第2の接着剤と同じである。
ポリプロピレンで作製され、坪量11g/m2を有する、長さ390mm及び幅130mmの不織布ウェブ(SMS、すなわちスパンボンド−メルトブローン−スパンボンド層)が第1の下側キャリア基材として使用された。
超吸収性ポリマー材料によって被覆されていない両方のキャリア基材の表面が外側を向くように、上側ラミネート層と下側ラミネート層は一緒に配置される。これによって、ラミネート吸収性コアは、第1のキャリア基材と第2のキャリア基材に包まれた超吸収性ポリマー材料(及び第1の接着剤及び第2の接着剤)と共に形成される。
本方法は、z方向におけるラミネート吸収性コアの分離に依存して(in dependency of)ラミネート吸収性コアにおける第1の接着剤によって超吸収性ポリマー材料に適用されている膨張制限圧力を測定する。
