Abstract

ベースウェブおよびベースウェブ上でハイドロエンタングリングされたエアレイ法で形成された繊維からなるウェブ。ウェブは、合成繊維、エアレイ法で形成されたセルロース繊維、あるいは、ベースウェブ上でフラフの形でエアレイ法で形成された合成繊維と混合された合成繊維もしくはセルロース繊維からなるベースウェブを含む。ウェブの重さは、８０〜２０００ｇ／ｍ２の間の重さである。本発明の特に丈夫なウェブは、例えば、段ボールあるいは熱および／または音を遮断する材料を製造するために有用に用いられ得る。

Description

【０００１】
本発明は、少なくとも、主に、合成繊維、エアレイ法で形成された（ａｉｒ−ｌａｉｄ）セルロース繊維、または、ベースウェブ上でフラフ（ｆｌｕｆｆ）の形でエアレイ法で形成された合成繊維と混合された合成繊維もしくはセルロース繊維からなるベースウェブを含むウェブ、ならびに、フラフをベースウェブ上でハイドロエンタングリング（ｈｙｄｒｏｅｎｔａｎｇｌｉｎｇ）することによって得られる構造に関する。
【０００２】
ハイドロエンタングリングプロセスの間、例えば１００バールの高さの圧力の影響下で、水のジェットが、多数のノズルからベースウェブ上の繊維フラフに向かって噴出される。
【０００３】
ベースウェブは、水のジェットからの重い負荷に耐えるために十分な強度を有する必要があり、従って、通常、合成繊維から製造される。
【０００４】
いくつかの場合において、ベースウェブは、スパンボンデッド／メルトブローン（ＳＭＭＳ）ウェブであってもよいが、通常は、エアレイ法で形成された繊維フラフのハイドロエンタングリングの間にエアレイ法で形成された繊維フラフのベースとして用いられる前に、ハイドロエンタングリングされ、乾燥された、カード法で形成された繊維から形成される。
【０００５】
従来、このようなウェブは、２０〜８０ｇ／ｍ２の間の重さであり、広い範囲で、使い捨ての不織布製品、例えば、女性用生理用品、大人用おむつ、ダイヤパー、ナプキン、ティッシュ、およびタオルの製造に用いられている。
【０００６】
しかし、本発明によるウェブは、８０〜２０００ｇ／ｍ２の間の重さの特に丈夫なウェブであり、このようなウェブは、ベースウェブおよびベースウェブ上にハイドロエンタングリングされたフラフだけでなく、異なる種類の層と積層され得る。
【０００７】
このような他の層の例として、ハイドロエンタングリングされたウェブの少なくとも１つの側面上のホットメルトされたプラスチックの層、および溶解されたプラスチック上の少なくとも１つの不織布ウェブが挙げられ得る。
【０００８】
他の層の他の例には、ウェブの少なくとも１つの側面上のメルトブローン繊維（ＳＭＭＳ）または複合繊維、ならびに／あるいは、これらの組合せの少なくとも１つの層が含まれる。
【０００９】
他の層の第３の例には、ウェブの少なくとも１つの側面上の少なくとも１つのカード法で形成されたウェブが含まれる。
【００１０】
他の層の第４の例には、ウェブの少なくとも１つの側面上の少なくとも１つのカード法で形成されたウェブ、および、ウェブの少なくとも１つの側面上の、例えばプラスチックの膜が含まれる。
【００１１】
上記の種類の特に丈夫なウェブは、通常、カレンダー法にかけられ、例えば、段ボール、あるいは、熱および／または音を遮断する材料を製造するために、有用に用いられ得る。
