Abstract
High-tenacity fibers with improved elongational properties particularly suitable for nonwovens such as geotextiles include a polypropylene composition. The polypropylene composition includes from 0.2 wt % to 7 wt % 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. The fibers may be made by a process including melt-spinning and drawing.
