Abstract
(EN)
Provided is a nonwoven fabric formed from composite fibers containing 40 mass% to 80 mass% of a propylene homopolymer (A) having a melting point (Tm–D), as measured by a differential scanning calorimeter (DSC), of greater than 120°C, 4 mass% to 40 mass% of a polypropylene resin (B) having a melting point (Tm–D), as measured by a differential scanning calorimeter (DSC), of 120°C or less, and 10 mass% to 55 mass% of a polyethylene resin (C), wherein the nonwoven fabric has a texture uniformity of 2.1 to 3.0 and a loft of 450 μm or greater.
(FR)
L'invention concerne un tissu non-tissé qui est configuré à partir de fibres composites contenant : 40% en masse ou plus à 80% en masse ou moins d'un homopolymère de propylène (A) de point de fusion (Tm-D)mesuré par calorimètre à compensation de puissance (DSC) supérieur à 120°C ; 4% en masse ou plus à 40% en masse ou moins d'une résine à base de polypropylène (B) de point de fusion (Tm-D)mesuré par calorimètre à compensation de puissance (DSC) inférieur ou égal à 120°C ; et 10% en masse ou plus à 55% en masse ou moins d'une résine à base de polyéthylène (C). L'uniformité de texture dudit tissu non-tissé est supérieure ou égale à 2,1 et inférieure ou égale à 3,0, et son gonflage est supérieur ou égal à 450μm.
(JA)
