Description
吸収性構造体115は、基材層116と、前記基材層116によって支持され、その上で不動化された吸収性ポリマー粒子及び任意選択的なセルロースを含む吸収性層117と、を含む三次元構造体である。吸収性構造体115の例を、図8、10A、10B、14、15A、及び15Bに示す。
吸収性層は、吸収性ポリマー粒子150を単独で、又はセルロース繊維などの他の材料と組み合わせて含み得る。吸収性ポリマー粒子は、例えば、熱可塑性接着剤140によって、基材層上で不動化され得る。
図20を参照すると、弾性ストランド26などの弾性部材は、これらがベルト部分の下側帯22”、23”に存在するが、シャーシ30上に置かれた下横方向中央帯22’、23’のうち一部又は全部には存在しないように、前側及び/又は後側ベルト部分22、23内に構成され得る。このように、一方又は両方のベルト部分を、不織布層25a、25b(図3を参照)などの弾性ストランド26を挟む層のうちの1つ又は2つ以上が、予歪みを加えられた弾性部材及び横方向にギャザーされた材料のひだべりの存在によって実現される弾性の伸長なしに、ベルト部分の下中央帯22’、23’に存在するように構成してもよい。シャーシの上に置かれた中央帯22’、23’では、一方又は両方のベルト部分22、23の不織布層は、これらがシャーシ上に横方向に伸張された状態で置かれる(即ち、これらが、さもなければ、予歪みを加えられ、かつ挟まれた横方向弾性ストランドによって付与されたであろう長手方向のひだべり又はしわ(例えば図4及び5に示されるひだべり又はしわ27)を有さないようにシャーシ材料(バックシートなど)に配置されて固着され得る)。この構成では、シャーシ30の下中央帯22’、23’に置かれ、長手方向のひだべりを有さないために、ベルト部分の他の弾性のひだべりを有する帯と比較して横方向の弾性的な伸長ができないか又はより少ない、完全に伸張されたベルト層材料は、横方向の拡張に対してより大きく抵抗して、シャーシ材料の抵抗を補い、吸収性層117の端部の支持及び拘束を補助するように構成される。その結果、吸収性層117によって液体が吸収された時の外向き膨張部219の突出部(図7に示すものなど)は、縮小され得る。この機構は、上記の吸収性層117の膨張部の突出部を縮小させる相乗効果の可能性のために、上記のチャネル構造のいずれかと組み合わせてもよい。こうして、図20に示す一実施例では、主長手方向チャネル126の前端部は、前側ベルト部分22の非弾性下中央帯22’の下に(着用者に面する側に向けて)配置してもよい。いくつかの例では、ベルト部分及びシャーシは、シャーシ上に置かれた非弾性部分を有するベルト構造の更なる例を説明する、PCT/CN2014/094890号に記載される機構を有するように構成され得る。
