Title (EN) SPUN-BONDED NONWOVEN FABRIC
(FR) TISSU NON TISSÉ FILÉ-LIÉ
(JA) スパンボンド不織布
Abstract:
(EN) The present invention provides a spun-bonded nonwoven fabric which is configured from polyolefin fibers that have excellent spinnability even if the single fiber diameter thereof is small, and which exhibits high flexibility and high uniformity. The present invention relates to a spun-bonded nonwoven fabric which is configured from fibers that are formed from a polyolefin resin and have a single fiber diameter of 6.5-14.5 μm, and which has a melt flow rate of 155-850 g/10 minutes and a CV value of the thickness of 13% or less.
(FR) Tissu non tissé filé-lié configuré à partir de fibres de polyoléfine qui ont une excellente aptitude au filage même si le diamètre de fibre unique de celui-ci est petit, et qui présente une flexibilité et une uniformité élevées. La présente invention concerne un tissu non tissé filé-lié qui est configuré à partir de fibres qui sont formées à partir d'une résine de polyoléfine et ont un diamètre de fibre unique de 6,5 à 118,5 µm, et qui a un indice de fluidité de 155 à 850 g/10 minutes et une valeur CV de l'épaisseur de 13 % ou moins.
(JA) 本発明は、単繊維繊維径が細径ながら紡糸性に優れたポリオレフィン繊維からなり、柔軟で均一性の高いスパンボンド不織布を提供する。本発明は、ポリオレフィン系樹脂からなる単繊維繊維径が6.5~14.5μmの繊維で構成され、メルトフローレートが155~850g/10分のスパンボンド不織布であって、厚みのCV値が13%以下のスパンボンド不織布に関する。
