Abstract
Description
本発明の複合ウェブに関連して使用される基材は様々な構造を有してよい。例えば基材は、織物材料、不織物材料、編物材料、網、スクリム、フォーム、紙、フィルム、またはニップポイントを通して供給され得る他の連続媒体であってよい。基材は、例えば伸展性、弾性、屈曲性、適合性、通気性、多孔性、剛性等などの多種多様な特性を有し得る。さらに基材は平坦な平面シート構成からプリーツ、しわ、マイクロクレーピングまたは他の変形を含んでもよい。加えて、本発明と関連して使用される基材は、活性化、すなわち使用前の伸長または伸展を必要としても、または必要としなくてもよい。
本発明の弾性複合構造の様々な成分は多種多様な異なるポリマー材料から形成されてよい。本発明と関連して使用されてもよいポリマー材料のいくつかの例としては、限定されないが、ポリウレタン、ポリオレフィン(例えば、ポリプロピレン、ポリエチレン等)、ポリスチレン、ポリカーボネート、ポリエステル、ポリメタクリレート、エチレン酢酸ビニルコポリマー、エチレンビニルアルコールコポリマー、ポリ塩化ビニル、アクリレート変性エチレン酢酸ビニルポリマー、エチレンアクリル酸コポリマー、ナイロン、フルオロカーボン等が挙げられる。適切なポリマー材料は一般的に、ASTM D 1238で詳述されるようなポリマーの適切な条件で測定される5〜200グラム/10分のメルトフローインデックスを有し得る。さらにいくつかの例では、弾性複合構造を構成するために使用されるポリマー材料の一種以上が、例えば熱可塑性ホットメルト接着剤であってよい。
