Abstract
Description
本発明は、使い捨て吸収性物品用の吸収性コア構造体に関する。より詳細には、本発明は、繊維状材料から構成される吸収性コア構造体に関する。
吸収性コア構造体を有する使い捨て吸収性物品は当該技術分野で既知である。さらに、このような吸収性コア構造体が少なくとも3つの機能領域、すなわち捕捉領域、分布領域及び貯蔵領域を有することも既知である。このような領域が既知である一方で、上記領域を有する吸収性コア構造体の設計は、現行の製造方法及び現行の材料選択によって制限される。
吸収性コア構造体は、少なくとも1つの捕捉領域と、少なくとも1つの分布領域と、少なくとも1つの貯蔵領域とを有する。捕捉領域は、繊維状材料から構成されている。捕捉領域は、約0.018g/cc〜約0.20g/ccの相対的に低い密度を有する。少なくとも1つの分布領域は、繊維状材料から構成されている。分布領域は、約0.024g/cc〜約0.45g/ccの相対的に中程度の密度を有するように圧密される。分布領域は、上記捕捉領域と流体連通している。貯蔵領域は、繊維状材料から構成されている。貯蔵領域は、約0.030g/cc〜約0.50g/ccの相対的に高い密度を有するように圧密される。貯蔵領域は、分布領域と流体連通している。繊維状材料が折り重なって上記吸収性コア構造体を形成する。繊維状材料は、ポリプロピレン、ポリエチレン、ポリエステル、ポリビニルアルコール、ポリビニルアセテート、澱粉、酢酸セルロース、ポリブタン、レーヨン、ウレタン、クラトン(商標)、ポリ乳酸、綿、リヨセル(商標)、生分解性重合体、繊維を形成するのに好適な任意の他の材料、及びそれらの組み合わせから成る群から選択されるものであってもよい。また、吸収性コア構造体は、高吸収性材料、例えば高吸収性重合体(SAP)及び/又は高吸収特性を有する他の材料を含んでいてもよい。高吸収性材料は、上記少なくとも1つの貯蔵領域に堆積されていてもよい。
本明細書中で用いられる用語の各種定義は以下の通りである。
Claims (4)

貯蔵領域(30)が繊維状材料から構成されており、貯蔵領域(30)が約0.030g/cc〜約0.50g/ccの相対的に高い密度を有するように圧密され、貯蔵領域(30)が分布領域(20)と流体連通している、少なくとも1つの貯蔵領域(30)とを有する吸収性コア構造体であって、
前記繊維状材料が折り重なって吸収性コア構造体を形成することを特徴とする吸収性コア構造体。 - 前記繊維状材料が、ポリプロピレン、ポリエチレン、ポリエステル、ポリビニルアルコール、ポリビニルアセテート、澱粉、酢酸セルロース、ポリブタン、レーヨン、ウレタン、クラトン(商標)、ポリ乳酸、綿、リヨセル(商標)、生分解性重合体、繊維を形成するのに好適な任意の他の材料、及びそれらの組み合わせから成る群から選択され得る、請求項1に記載の吸収性コア構造体。
- 前記少なくとも1つの貯蔵領域(30)に堆積される高吸収性重合体(80)をさらに特徴とする、請求項1に記載の吸収性コア構造体。
