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 presente invención se dirige generalmente a tramas no tejidas similares a telas. Más específicamente, la presente invención está dirigida a un tejido unido por hilado hecho de una mezcla polimérica que incluye una poliolefina de alta tacticidad tal como polipropileno, una poliolefina de baja tacticidad tal como polipropileno y un copolímero de propileno-etileno para mejorar la suavidad de una trama no tejida.
