Description
図1乃至図2を参照して、本発明の第1実施形態に係る吸収性物品について説明する。図1は、本発明の第1実施形態に係る吸収性物品100の平面図であり、図2は、吸収性物品100のA−A´線断面図である。
本実施形態に係る吸収性物品100における吸熱材50の配置領域について説明する。***された経血によって、吸熱反応を効率的に発現させるためには、吸熱材50の配置領域225は、着用者の股間部に当接する領域を少なくとも含むことが好ましい。
本実施形態に係る吸熱材50の粒径について、図3を参照して説明する。図3は、本実施形態に係る吸熱材の粒度分布を示すグラフである。また、図3において、横軸が粒径を示し、縦軸が全体重量に対する割合(%)を示す。
本実施形態に係る吸熱材50の構成について説明する。吸熱材50は、被覆材によって、吸熱材50のみを被覆したシートを吸収体30の上面に配置してもよいし、パルプとパルプとの間に層状に吸熱材50を配置してもよい。さらに、吸熱材50は、表面シート10と吸収体30の間に挟みこんでもよい。
本実施形態に係る吸収体30における吸熱材50の混入量について説明する。吸熱材50の混入量は、吸熱材50の種類によって溶解熱や溶解度が異なることや、吸熱材50の配置位置によっても影響される。ここで、肌表面と吸収性物品100との間の空間における温度及び湿度の急激な上昇を抑制させる点と、着用者へ冷感などの不快感を与えない点とを考慮すると、吸収性物品100の1枚当たりの吸熱材50の重量は、0.1〜10gの範囲、より具体的には、0.5〜5gの範囲が好ましい。
図4を参照して、本発明の変形例1に係る吸収性物品について、本発明の第1実施形態に係る吸収性物品との相違点に着目して説明する。
本発明の変形例2に係る吸収性物品について、本発明の第1実施形態に係る吸収性物品との相違点に着目して説明する。
図5を参照して、本発明の第2実施形態に係る吸収性物品について説明する。以下、本発明の第2実施形態に係る吸収性物品について、本発明の第1実施形態に係る吸収性物品との相違点に着目して説明する。図5は、本発明の第2実施形態に係る吸収性物品110の平面図である。
上述の実施形態では、吸収性物品として生理用ナプキンを例に挙げて説明してきたが、本発明は、生理用ナプキンに限定されることはなく、パンティーライナー等の女性用の吸収性物品や、失禁パッドやオムツにも適用可能である。
まず、肌と吸収性物品との間の空間を再現するため、かつ着用中の体液拡散状態を再現するために、図6(a)乃至(b)に示すような実験装置を作製した。図6(a)は、実験装置の横断面図であり、図6(b)は、実験装置の縦断面図である。
吸熱材を配置した吸収体を有するサンプル1を生製した。具体的に、まず、吸収体の上層材として、パルプ150gsmと塩化カリウム1.5gをブレンドし、長手寸法100mm、幅寸法30mmに成形した。
生製したサンプル1を用いて、下記の方法によって、評価実験を行った。なお、評価実験は、35℃±5℃、75RH%±5RH%の環境下にて行った。
図7(a)乃至(b)は、上記評価実験によって得られた温度及び湿度の測定結果である。なお、図7(a)は、湿度の測定結果であり、図7(b)は、温度の測定結果である。
得られたサンプル1を用いて、下記の評価実験を行った。なお、評価実験は、35℃±5℃、75RH%±5RH%の環境下にて行った。
図8(a)乃至(b)は、上記評価実験によって得られた温度及び湿度の測定結果である。なお、図8(a)は、湿度の測定結果であり、図8(b)は、温度の測定結果である。
上述した評価実験及び評価結果より、体液の***が繰り返される場合や、体液の***量が多い場合であっても、サンプル1は、肌表面と吸収性物品との間の空間における温度及び湿度の急激な上昇が抑制できることがわかった。また、サンプル1は、密閉空間の温度がサンプル2に対して極端に低下していないことで、着用者に対して冷感などの不快感を与えない程度であることもわかる。
塩化カリウムを例に、粒径の異なる塩化カリウムが、水和により完全溶解する速度について評価実験を行った。
まず、実験液の温度を体液温度と合わせるために、37℃±5℃に調整した。
上記評価実験によって、下記の測定結果が得られた。
サンプルB:平均粒径範囲(355〜500μmの範囲) :52分43秒
サンプルC:粒径が小さい範囲(150〜250μmの範囲):25分37秒
(実施例2に係る考察)
上述した評価実験及び評価結果よれば、実験液の滴下量や実験環境の温湿度にも依存する場合もあるが、傾向として、粒径が大きい吸熱材ほど完全溶解する速度が遅くなることがわかった。つまり、粒径が異なる吸熱材を配合することで、吸熱反応を長時間発現させることができることがわかった。
