Description
多成分繊維は、連続フィラメント、ステープル繊維、又は溶融吹込繊維(meltblown fiber)でありうる。好ましい実施形態では、繊維は、鞘−コア構造ドメインに配列されたポリマー成分を用いた二成分繊維である。本発明のこの態様で、コアは、繊維に、そして順次、それを用いて製造された布に、所望の特性を付与するポリマーブレンドから形成される。
この実施例は、コアが、少なくとも2つの異なるポリオレフィンポリマーの多ポリマーブレンドから形成され、ポリマーが、高融点主要連続相として存在し、そして少なくとも1つの低融点不連続相がそこに分散されることを特徴とする本発明の連続二成分繊維を用いて製造された布の製造及び利益を示す。高融点連続相は、プロピレンポリマーを含み、そして低融点不連続相は、ポリエチレンポリマーを含む。
この実施例は、コアが、微量相として特定グレードのポリプロピレン又はコポリエチレンと混合した主要相として特定グレードのポリエチレンのブレンドから形成されることを特徴とする本発明の連続二成分繊維を用いて製造された布の製造及び利益を示す。さらに、繊維コアは、少なくとも2つの異なるポリオレフィン・ポリマーの多ポリマーから形成され、そしてポリマーは、高融点主要連続相、そしてそこに分散される少なくとも1つの低融点不連続相として存在する。高融点連続相は、プロピレンポリマーを含み、そして低融点不連続相は、ポリエチレンポリマーを含む。
本発明の布の繊維構造内に含まれるような不連続ポリマー相のドメイン・サイズ及び分布を測定する調査が行われた。その終了に向けて、スパンボンド法の不織布を、本出願の教示にしたがって製造した。特に、27の溶融指数を示す85重量パーセントの線状低密度ポリエチレン(LLDPE)(ダウ6811A LLDPE)及びおよそ24の溶融フローを示す15重量パーセントのポリプロピレン(PP)ポリマー(アプリル3250YR1PP)を含むポリマーブレンドを、回転混合機で乾式混錬させた。その後、乾式混錬混合物を、スパンボンド法の不織紡績システムの押出機の供給ホッパーに導入した。連続フィラメントを、およそ600m/分のフィラメント速度で、スロット圧伸成形加工によって溶融紡績し、そして集合表面上に堆積させて、スパンボンド法の不織ウエブを形成し、そしてそのウエブを、12%結合領域を示すパターン化ロールを用いて、熱で結合させた。そのように製造されたサンプルは、実施例Aとして引用される。
