(FR) TISSU NON TISSÉ FILÉ-LIÉ
(JA) スパンボンド不織布
Abstract: front page image
(EN)The purpose of the present invention is to obtain spunbonded nonwoven fabric which comprises thin hollow fibers and which has excellent lightweight properties and evenness and has high strength and flexibility. This spunbonded nonwoven fabric is characterized by comprising hollow fibers of a propylene polymer which satisfy the following requirements (a) to (c): (a) to have a degree of C-axis orientation of at least 0.85; (b) to have an average fiber diameter of 5-20 µm; and (c) to have a percentage of hollowness of 5-30%.
(FR)La présente invention concerne un tissu non tissé filé-lié qui comprend des fibres creuses minces et qui possède d'excellentes propriétés de légèreté et une excellente uniformité et qui possède une haute résistance et une haute flexibilité. Ce tissu non tissé filé-lié est caractérisé en ce qu'il comprend des fibres creuses d'un polymère propylène qui satisfont les conditions suivantes (a) à (c) : (a) présenter un degré d'orientation d'axe C d'au moins 0,85 ; (b) présenter un diamètre moyen de fibre de 5 à 20 µm ; et (c) présenter un pourcentage de creux de 5 à 30 %.
(JA) 本発明の課題は、軽量性、均一性に優れ、しかも、強度が高く、柔軟性を有する細繊維の中空繊維からなるスパンボンド不織布を得ることを目的とするものであり、本発明は、下記(a)~(c)の要件を満たすプロピレン系重合体の中空繊維からなることを特徴とするスパンボンド不織布である。 (a)C軸配向度が少なくとも0.85、 (b)平均繊維径が5~20μm、及び (c)中空率が5~30%。
