FIBERS AND NONWOVENS WITH IMPROVED MECHANICAL AND BONDING PROPERTIES |
摘要 |
The present invention relates to fibers, particularly to as-spun fibers, having improved properties, in particular improved bonding performance and mechanical properties. In particular, the present invention relates to fibers comprising a metallocene random copolymer of propylene and one or more comonomers, said metallocene random copolymer having a broader molecular weight distribution. The present invention further relates to nonwovens comprising such fibers and to a process for producing such fibers and nonwovens. The fibers and the nonwovens of the present invention are characterized by improved properties, in particular improved bonding performance and mechanical properties, when compared to the prior art fibers and nonwovens. |
