Description
ポリプロピレン樹脂を溶融紡糸して、繊度がそれぞれ1〜2D、4〜6Dに形成された下層ウェブS1及び上層ウェブS2の長繊維不織布シートをそれぞれ製造し(幅:1000mm)、前記下層ウェブS1及び上層ウェブS2シートは、上部ロールに円形状パターンと直線状パターンとが組み合わせられて形成された熱エンボスロールに供給して、厚さが0.08〜0.48mmであり、目付が10〜60g/m2である長繊維不織布ループを製造した。前記エンボスロールにより上層ウェブS2に長手方向に連続して形成される融着部の幅を1.0mmに、且つ、融着部同士の間隔を約4mmに設定することにより、不織布ループに形成される貼り合わせ領域は、全体の表面積を基準として約20%であり、非融着部は約80%である。前記下層ウェブS1及び上層ウェブS2により構成される長繊維不織布シートの繊度が異なる不織布ループの配合を下記表1に示す。
比較例1から比較例6においては、実施例における下層ウェブS1及び上層ウェブS2の長繊維不織布シートを上部ロールに波打ち状のパターンが形成された熱エンボロールに供給することを除いては、実施例1から実施例6の方法と同様にして、下層ウェブS1及び上層ウェブS2の長繊維不織布シートの繊度がそれぞれ1〜2D、4〜6Dである長繊維不織布ループを製造した。
前記実施例及び比較例に係る製品に対して、目付、厚さ、引きはがし強さ、せん断強さ、通気度などを下記に示す方法で測定し、その性能指標に対する実験結果の平均値を下記表2に示す。
