Description
本発明は、強靭で柔かい穿孔不織ウェブに、さらに詳細には、使い捨て吸収体に使用して好適な、強靭で柔らかい不織ウェブに関わる。
おむつや、成人失禁用製品のような使い捨て吸収体は、当分野においてよく知られる。このような吸収体は、装着者によってその上に集積させられた尿や大便物質を収集・保持する。
本発明は、おむつのような使い捨て吸収体のトップシートとして使用されてもよい不織ウェブである。この不織ウェブは、各々接着領域を有する、第1または中央ゾーンと、少なくとも1つの第2または外方ゾーンを備える。同ウェブは、1つの中央ゾーンと、一対の外方ゾーンを備えることが好ましい。前記外方ゾーンの接着領域は、前記中央ゾーンの接着領域よりも大きい。中央ゾーンは、少なくとも約10%の効果的開放領域と、少なくとも0.2平方ミリメートルの効果的サイズを持つ複数の開孔を有する。
ここで使用されている「吸収体」という用語は、身体排泄物を吸収・包含する装置、より詳細には、身体から排泄される各種排泄物を吸収・包含するために、装着者の身体に密着して、または、近接して設置される装置を指す。ここで使用されている「使い捨て」という用語は、吸収体として洗濯、その他の回復、または再使用を意図されることのない吸収体を記述するのに使用される(すなわち、1回の使用後の廃棄を意図されるが、好ましくは、再使用、肥料用、またはその他の環境適合的やり方で処理されることが意図される)。「一体型」吸収体とは、吸収体であって、同吸収体において、別個の部分がまとめられて統合された実体を形成し、それによって、別個のホルダーやライナーのような別個の操作部品が必要とされない、そのような別個の部品から形成される吸収体を指す。
Claims (5)
- 接着不織ウェブの形成法であって、前記方法は、
a)ウェブを、中央ゾーンを備える第1ゾーンにおいて接着領域で接着する工程、
b)前記ウェブを、少なくとも一つの外方ゾーンを備える第2ゾーンにおいて、中央ゾーンの接着領域よりも大きな接着領域で接着する工程、
c)前記中央ゾーンを、同中央ゾーンが複数の開孔を持ち、かつ、少なくとも25%の効果的開放領域を有するように開孔する工程、
d)前記ウェブを、冷却する工程、及び、
e)前記ウェブを、2つのローラーによって形成される噛み合わせを通るように供給する工程、
を備えており、
前記2つのローラーは、同じ速度を有し、かつ、滑らかな外面を有しており、開孔周囲の回りに延びた固く融合した材料を破壊するようになっている
ことを特徴とする方法。 - 前記開孔は、少なくとも0.2平方ミリメートルの効果的サイズを有する
ことを特徴とする請求項1に記載の方法。 - 前記中央ゾーンは、12%未満の接着領域を有する
ことを特徴とする請求項1または2に記載の方法。 - 前記外方ゾーンは、15%よりも大きな接着領域を有する
ことを特徴とする請求項1乃至3のいずれかに記載の方法。 - 前記ウェブは、一対の外方ゾーンを備える
ことを特徴とする請求項1乃至4のいずれかに記載の方法。
