HIGH-TENACITY DRAWN FIBERS OF A POLYPROPYLENE COMPOSITION WITH IMPROVED ELONGATIONAL PROPERTIES AND NONWOVENS

摘要

The present invention relates to high-tenacity fibers with improved elongational properties particularly suitable for non wovens such as geotextiles, consisting of polypropylene compositions comprising from 0.2 wt% to 7wt% of a rubber in a dispersed phase. The fibers have a tensile strength of at least 45 cN/tex measured in accordance to ISO 2062-B. Further the present invention relates to a process for the production of such fibers.
