Abstract
【解決手段】吸収性コア構造体を製造する方法は、少なくとも1つの繊維状材料層を融解紡糸する工程を含む。少なくとも1つの凹部が形成され、前記繊維状材料層中の実質的に平行な列の少なくとも2つの凸部を分離する。前記第1繊維状材料層の第1部分は、前記第1繊維状材料層の第2部分に折り重ねられ、前記第1繊維状材料層の少なくとも一部分は高密度化される。

Description
用語「吸収性物品」とは、本明細書では身体の浸出物を吸収及び収容する装置のことをいい、より詳しくは、身体から放出された種々の浸出物を吸収及び収容するために着用者の身体に当てて置かれるか、又は身体の近傍に置かれる装置のことをいい、例えば失禁用ブリーフ、失禁用下着、吸収性挿入物、おむつカバー及びライナー、並びに女性生理用衣服等が挙げられる。吸収性物品は、衣服面及び身体面を有する吸収性コアと、この吸収性コアの身体面に隣接して配置された液体透過性表面シートと、吸収性コアの衣服面に隣接して配置された液体不透過性背面シートとを有するものであってもよい。
例えば、当業者は、SAP堆積が種々の適当な技法によって達成可能であることを理解するだろう。これらの技法として、限定されるものではないが、凸部及び凹部を形成した後の位置合わせSAP堆積又は凸部/凹部形成工程でのSAP堆積が挙げられる(例えば、SAPが拡散部材の周りの繊維に追従しなければならない加工ビームアテニュエータの先端にSAPを付加する)。
