(EN) FIBROUS NONWOVEN FABRIC
(FR) TISSU NON TISSÉ FIBREUX
Abstract
(EN) Provided is a fibrous nonwoven fabric including a resin composition (C) containing a high-crystalline polyolefin (A) and a low-crystalline polyolefin (B), wherein a half-crystallization time (t c ) of the resin composition (C) is 1.2 to 2.0 times a half-crystallization time (t a ) of the high-crystalline polyolefin (A).
(FR) L'invention concerne un tissu non tissé fibreux constitué d'une composition résineuse (C) comprenant une polyoléfine hautement cristalline (A) et une polyoléfine faiblement cristalline (B). L'invention est caractérisée en ce que la composition résineuse (C) présente une durée de semi-cristallisation (tc) qui représente 1,2 à 2,0 fois la durée de semi-cristallisation (ta) de la polyoléfine hautement cristalline (A).
