Description
図1及び図2を参照して、吸収性物品の構成を説明する。図1は、本実施の形態に係る吸収性物品の製造方法によって製造された吸収性物品の平面図であり、図2は、図1に示すA−A断面図である。本実施形態に係る吸収性物品1は、生理用ナプキンである。
次いで、図3を参照して、吸収性物品の製造方法について説明する。図3は、吸収性物品の製造方法を説明するための図であり、工程を模式的に示している。図3(a)は、各工程を上方から視認した状態の図であり、図3(b)は、図3(a)に示すB−B線に沿った模式断面図である。なお、図3において、パルプを積層する積層ドラム101、及びエンボス加工を施すエンボスロール102については、装置内部を省略して示す。
吸収性物品の製造方法は、表面シート10に圧搾溝60を形成した後に、高吸収性ポリマー層31と表面シート10を積層する。よって、高吸収性ポリマー層31の被覆シートがエンボス加工によって破れることがない。よって、被覆シートの破れによって高吸収性ポリマーの粒子が吸収性物品1の肌対向面側T1に露出することを抑制する。高吸収性ポリマーの粒子が零れることによる吸収性能の低下や、高吸収性ポリマーの粒子が肌に触れることによる装着感の悪化を抑制できる。
上述したように、本発明の実施形態を通じて本発明の内容を開示したが、この開示の一部をなす論述及び図面は、本発明を限定するものであると理解すべきではない。この開示から当業者には様々な代替実施の形態、実施例及び運用技術が明らかとなる。
