Beschreibung
Zusammenfassung:	The present invention is generally directed to cloth-like nonwoven webs. More specifically, the present invention is directed to a spunbond fabric made from a polymer blend that includes a high tacticity polyolefin such as polypropylene, a low tacticity polyolefin such as polypropylene and a propylene-ethylene copolymer for improving softness of a nonwoven web. La présente invention concerne de manière générale des nappes non tissées de type étoffe. Plus particulièrement, la présente invention concerne un tissu filé-lié fabriqué à partir d'un mélange de polymères qui comprend une polyoléfine à tacticité élevée telle qu'un polypropylène, une polyoléfine à tacticité faible telle qu'un polypropylène et un copolymère de propylène-éthylène pour améliorer la souplesse d'une nappe non tissée.
