Abstract
【解決手段】不織布からなる透液性トップシート3と、バックシート2との間に吸収体4が介在されるとともに、前記透液性トップシート3の外面側から圧搾溝7,7を付与してある生理用ナプキン1において、前記透液性トップシート3として、繊度1.7dt以下の不織布を用いるとともに、この透液性トップシート3の下層面側であってかつ前記圧搾溝7,7を含む範囲に、繊度が1.7dtよりも大きい圧搾補強用不織布8を1又は複層配設する。
【選択図】図1
Description
前記透液性トップシートとして、繊度1.7dt以下の不織布を用いるとともに、この透液性トップシートの下層面側であってかつ前記圧搾溝を含む範囲に、繊度が1.7dtよりも大きい圧搾補強用不織布を1又は複層配設したことを特徴とする吸収性物品が提供される。
〔吸収性物品の構造例〕
図1は本発明に係る生理用ナプキン1の一部破断展開図、図2は図1のII−II線矢視図である。
前記不透液性バックシート2は、ポリエチレンやポリプロピレン等のオレフィン系樹脂シートなどの少なくとも遮水性を有するシート材が用いられるが、この他にポリエチレンシート等に不織布を積層したラミネート不織布や、さらには防水フィルムを介在して実質的に不透液性を確保した上で不織布シート(この場合には防水フィルムと不織布とでバックシートを構成する。)などを用いることができる。近年はムレ防止の観点から透湿性を有するものが用いられる傾向にある。この遮水・透湿性シート材は、ポリエチレンやポリプロピレン等のオレフィン系樹脂中に無機充填剤を溶融混練してシートを成形した後、一軸または二軸方向に延伸することにより得られる微多孔性シートである。
〔他の形態例〕
(1)上記形態例においては、所謂セカンド不織布を配置していないが、これを透液性トップシート3と吸収体4との間に配置するようにしてもよい。この場合は、前記圧搾補強用不織布8と吸収体4との間に配設することになる。
(2)上記形態例では、生理用ナプキン1の略長手方向に沿う左右一対の圧搾溝7,7のみを形成した例であるが、圧搾溝は、生理用ナプキン1の略幅方向に沿う圧搾溝を含んでいてもよい。この場合は、この幅方向に沿う圧搾溝をも含むように、前記圧搾補強用不織布8が配設される。
(3)また、吸収体の構造は、上記形態例のように1層でフラットな吸収体4はもちろんのこと、排血部Hを含む範囲に使用面側に隆起する中高吸収体を有する構造であってもよい。
Claims (5)
- 不織布からなる透液性トップシートと、バックシートとの間に吸収体が介在されるとともに、前記透液性トップシートの外面側から圧搾溝を付与してある吸収性物品において、
前記透液性トップシートとして、繊度1.7dt以下の不織布を用いるとともに、この透液性トップシートの下層面側であってかつ前記圧搾溝を含む範囲に、繊度が1.7dtよりも大きい圧搾補強用不織布を1又は複層配設したことを特徴とする吸収性物品。 - 前記圧搾補強用不織布は、繊度2.2dt以上のものを用いる請求項1記載の吸収性物品。
- 前記圧搾補強用不織布は、各圧搾溝毎に分割して配設してある請求項1、2いずれかに記載の吸収性物品。
- 前記圧搾補強用不織布は、各圧搾溝毎に、かつ該圧搾溝の形状に沿って配設してある請求項1,2いずれかに記載の吸収性物品。
- 前記透液性トップシートとして用いた繊度1.7dt以下の不織布は、PET(ポリエチレンテレフタレート)/PE(ポリエチレン)の芯鞘型複合繊維としてある請求項1〜4いずれかに記載の吸収性物品。
