- 複数の加工凸型が所定の配置で全周面にわたって一様に設けられた圧印加工ローラを少なくとも一方に備えた一対のローラを所定の間隔で相対向して対置し、少なくともパルプと高吸収ポリマーとを混合した吸収要素物を液透過性シートで覆ってなる幅が一定の帯状の吸収体素体を、前記一対のローラ間に送り込みながら移送することにより、前記吸収体素体の少なくとも一面に、前記各加工凸型により平面視線形の溝状に押し潰した複数の線形状パターンを、何れも個々に離間し、且つ千鳥状に散在する配置に形成し、その後所定の寸法に切断する吸収体の製造方法であって、
前記線形状パターンを、吸収体素体の移送方向に対する傾きである配向角度が何れの箇所においても50°以下となる線形状に形成するとともに、前記吸収体素体の移送方向に対し直交する幅方向の直線を横切る本数が前記移送方向に沿った何れの箇所の各直線においても同一数で、且つ前記幅方向において一定間隔となる配置に形成したことを特徴とする吸収体の製造方法。 - 前記圧印加工ローラによって、5.56〜13.89kgf/cmの線圧で前記吸収体素体を押し潰して、線形状パターンを形成するようにした請求項1に記載の吸収体の製造方法。
- 請求項1または2に記載の製造方法により製造された吸収体であって、
綿状パルプと高吸収ポリマーとを混合してなる吸収要素物を液透過性の収納袋内に収容して封止した長方形の吸収体素体の少なくとも一面に、平面視線形の溝状となった複数の線形状パターンが、何れも個々に離間し、且つ千鳥状に散在する配置で形成され、
前記吸収体素体における前記線形状パターンの未形成部分が3mm以下の厚みに形成され、
前記線形状パターンが、吸収体素体の移送方向に対する傾きである配向角度が何れの箇所においても50°以下となる線形状に形成されるとともに、前記吸収体素体の移送方向に対し直交する幅方向の直線を横切る本数が前記移送方向に沿った何れの箇所の各直線においても同一数で、且つ前記幅方向において一定間隔となる配置に形成されていることを特徴とする使い捨ておむつ用吸収体。 - 前記線形状パターンは、前記吸収体素体の移送方向に対し45°の配向角度で左右何れかの方向に傾斜し、移送方向に沿って同一の傾斜方向のものを一定間隔で間欠的に配列してなるパターン列を移送方向に対し直交する幅方向に複数列並べるとともに、幅方向に沿って傾斜方向が異なるパターン列を交互に配し、且つ幅方向に隣接する各二つのパターン列を移送方向で隣接する線形状パターンの間隔分だけ移送方向にずらした配置で形成されている請求項3に記載の使い捨ておむつ用吸収体。
- 前記線形状パターンは、各箇所における移送方向に対する配向角度が何れも50°以下となるようなS字形状として、千鳥状に散在する配置で形成されている請求項3に記載の使い捨ておむつ用吸収体。
