Abstract
Description
−第1の層は、体液を吸収して第2の層に移すための層であり、
−第2の層は、第1の層から体液を受け取り、この第2の層に体液を拡散させるための層であり、ならびに
−第3の層は、第2の層から体液を受け取るための高吸水性ポリマー(SAP)粒子を含み、
第2の層は、体液を第3の層に不可逆的に転送する。
これにより、本発明は、体液が、吸収層として機能する第1の層から第3の層まで浸透し、第2の不織布層が、従来の分散層として、表面単位当たりの液量を減少させるのに役立つことを保証する。しかしながら、本発明の第2の層は、さらに、逆止弁のように機能し、第3の層から第1の層への流体の移動を防止するか、又は少なくとも強く制限する。
体液を第3の層に不可逆的に転送するために、第2の層には、繊維が粗い繊維(約>7dtex)である第3の層の空隙容積よりも小さい空隙容積が配置され、第2の層の繊維はより微細である。
−第1と第3の層間に液体の吸収勾配を生み出し、SAPの配置によるゲルの遮断を回避することによる、SAP粒子によって生じる改善された吸引効果、及び
−これら2つの層間の空隙容積の差異によって生じる第3と第2の層間の改善された逆流防止効果。
この後者の場合、本発明の多層シート材料は、吸収(吸水)分散層及び吸収層として両方機能する。したがって、本発明の多層シート材料は、浸透性のトップシートと不浸透性のバックシートとの間に直接挟むことができる。
前の実施形態と組み合わせることができる別の実施形態では、少なくとも1つの層は、連続空隙空間を含むことができる。連続空隙空間とは、不織布材料のない空間を指す。これらの連続空隙空間は、不織布層の繊維間で測定された空隙容積とは異なる概念であり、むしろ不織布層のはるかに大きなサイズのカット又は穴を指す。そのような空間は、例えば、不織布の断片が以下に記載されるように切断及び再配置される場合、層の厚さ全体にわたって配置され、又は例えば、1つ又は複数の層が接合工程にかけられた場合、層の厚さの一部のみにわたって配置され得る。
−SAP粒子を第3の層の表面の少なくとも一部に沈着させるステップ、及び
−SAP粒子を第3の層に含浸させるステップ、
を含む。
−SAP粒子の沈着前に、第3の層の表面にマスクを適用するステップ、
−少なくとも第3の層を接合するステップ、
−第3の層を断片に切断し、互いに分離した第2の層上に断片を接着させるステップ、
のうちの少なくとも1つのステップを含むことができる。
−少なくとも1つの層を断片に切断し、互いに分離した隣接層上に断片を接着させるステップ、
−少なくとも1つの層を接合するステップ、
のうちの少なくとも1つステップを含むことができる。
第1の層21は、空隙27を形成するように相互に結び付いた繊維26、好ましくは粗い繊維を含む。
第2の層22は、第1の層21の粗い繊維よりも密集している細い親水性繊維28でできている。細い繊維28は、空隙29を形成するように相互に結び付いている。
第3の層23は、空隙31を形成するように相互に結び付いている粗い繊維30、好ましくはかなり親水性の繊維を含む。いくつかのSAP粒子24は、第3の層23内、空隙31内に分散している。
あるいは、特に創傷被覆材の場合、第3の層は、身体により近くなることを意図した層であり得る。
同様に、第2の層の一面又は他面と接触して、1つ又は複数の追加の分散層を追加することができ、おそらくその中に分散したSAP粒子を含む、1つ又は複数の追加の粗い繊維層を第2の層と第3の層との間に追加することができる。膨潤能力又はサイズなどの種々の特性を有するSAPを種々の不織布層に分散させることができると想像できる。
次に、本発明の多層吸収分散シート材料を調製するための方法について説明する。
本発明の多層シート材料は、当業者に知られているように、例えば、3つの層を別々に作製し、次に、接合又は接着によりそれらを一緒に組み合わせることによって作製することができる。
それはまた、いくつかのカードウェブを作製することによって作ることができ、各ウェブは特定の種類の繊維又は繊維のブレンドを含み、ウェブを重ね合わせ、次に、繊維を相互に結び付ることによって、例えば熱接着により、1つの接着ステップで多層不織布が作り出される。あるいは、層の一部は、相互に結び付き不織布にされるカードウェブから作製でき、次いで、層は、接合又は接着によって別の層と組み合わされる。
図7を参照すると、ステップAにおいて、SAP粒子74は、本発明の第3の層に対応する不織布層73の表面に適用される。ここで、粒子74は、マスク75により沈着メカニズムが遮断される特定のパターンに従って適用され、この領域は、意図されるチャネル76に対応する。粒子の沈着は、例えば粉末散乱などの任意の適切なメカニズムによって実行することができる。粒子を均一に分散させるためには、マスクは使用されない。
接合領域95の表面に残存し得るSAP粒子は、例えば、エアブロー、吸引、又はブラッシングなどの様々な技術を使用して除去することができる。
ステップKにおいて、次に、接合層112及び113を第1の層111に組み合わせ、それにより、この場合、第3の層にチャネル、ならびに第2及び第3の層に連続空隙空間を含む不織布シート材料を形成することができる。図11の特定の場合において、第3の層113において、チャネル及び連続空隙空間115は重なり合うが、これは必ずしもそうでなくてもよい。この構成は、創傷被覆材にとって特に興味深い場合がある。この場合、第3の層は、身体部位に近い層であり、すなわち、おむつのような他の製品と比較して反対の構成であり得る。
ステップHにおいて、SAP粒子104は、材料シートの表面上に沈着される。本図に示されている沈着は非選択的であり、SAP粒子は隙間と第3の層の断片103iとの両方に蓄積する。
しかしながら、不織布断片103i上に粒子を選択的に沈着させるためにマスクを使用することが予見され得る。
ステップIにおいて、SAP粒子104は、例えば、Fibroline技術又は他の任意の適切な技術を使用して、不織布断片103iに含浸される。
断片103iの頂部及び断片間の隙間に分散されるSAP粒子104の両方が断片103iに含浸され、断片103i間の隙間又はチャネル105にはSAP粒子がない状態になる。
−第3の層におけるSAPの連続的又は不連続的な分散であり、後者の場合、チャネルを形成する、
−3つの層のうちのいずれか又は複数層において、連続空隙空間がない、又は連続空隙空間がある、
−連続空隙空間及びチャネルが存在する場合、それらは整列している、又は整列していない、
−連続空隙空間は、接合により、又は機械的切断及び層断片の配置により得られる。
SAP粒子又は不織布シート材料の任意の繊維は、臭気制御のために処理することができる。SAP粒子は、種々の特性を混合するために、様々な種類のSAP粒子を含み得る。
衛生用品用の150gsmの3層吸収及び分散シート不織布材料(ADL)は、
−重量の25%(37.5gsm)に対応し、2dtex〜28dtexの力価を持つPET繊維とPET/coPET繊維のブレンドで構成される第1層。
−重量の25%(37.5gsm)に対応し、0dtexから7dtexの力価を持つPET繊維とPET/coPET繊維のブレンドで構成される第2の層。
−重量の50%(75gsm)に対応し、2dtexから28dtexの力価を持つPET繊維とPET/coPET繊維のブレンドで構成される第3の層。
第1層は、身体に当たることが意図される側にある材料に対応する。
ADLの通気性の測定値は2500±500l/m2/sである。
EDANAアッセイWSP70.3.R3では、サンプルの裏抜け(strikethrough(ST))時間は0.59秒である。
EDANAアッセイWSP80.10では、サンプルの液戻り(wetback(WT))は0.09gである。
70mlの合成尿(生理食塩水0.9%NaCl)を4回添加し、添加の間の待機時間は5分であった。各添加の吸収時間は、クロノで測定される。4回目の待機時間の後、19cm×10cmのいくつかのリウェット紙をサンプル上に15秒間置き、リウェット紙によって吸収された液体の量を測定することによって、リウェットを測定する。吸収及びリウェット中の負荷は、8kgである。
