Title (EN) FILAMENT NONWOVEN FABRIC
(FR) TISSU NON TISSÉ EN FIL CONTINU
(JA) 長繊維不織布
Abstract: front page image
(EN)A filament nonwoven fabric which is composed of a hollow fiber having excellent strength, especially a hollow fiber having high single fiber strength which has high hollow rate even when formed into a thin fiber. Specifically disclosed is a filament nonwoven fabric composed of a hollow fiber of a propylene polymer which has a ratio of the Z average molecular weight (Mz) to the weight average molecular weight (Mw), (Mz/Mw) of 1.5-1.9, preferably with the ratio of the weight average molecular weight (Mw) to the number average molecular weight (Mn), (Mw/Mn) being within the range of 2.0-2.9.
(FR)L’invention concerne un tissu non tissé en fil continu composé d’une fibre creuse présentant une excellente résistance, en particulier une fibre creuse présentant une résistance monofibre élevée possédant un taux de creusement élevé même lorsqu’il est formé à l’intérieur d’une fibre mince. L’invention concerne en particulier un tissu non tissé en fil continu composé d’une fibre creuse en polymère de propylène présentant un rapport du poids moléculaire moyen Z (Mz) à la masse moléculaire moyenne pondérale (Mw), (Mz/Mw) de 1,5-1,9, de préférence avec le rapport de la masse moléculaire moyenne pondérale (Mw) à la masse moléculaire moyenne en nombre (Mn), (Mw/Mn) dans la plage de 2,0-2,9.
(JA) 強度に優れた中空繊維、とりわけ単糸強度が強く、しかも、細繊維にした場合でも中空率が高い長繊維不織布を開発することを目的とする。 Z平均分子量(Mz)と重量平均分子量(Mw)との比(Mz/Mw)が1.5~1.9、好ましくは、重量平均分子量(Mw)と数平均分子量(Mn)の比(Mw/Mn)が2.0~2.9の範囲にあるプロピレン系重合体の中空繊維からなる長繊維不織布を提供するものである。
