<p>The invention relates to non-postdrawn polyolefin fibers with high tenacity values of 2,0 to 5,0 cN/dtex, consisting essentially of predominantly isotactic propylene polymers having a crystallisation temperature of < 116 °C (DSC) and 0,001 to 2 % by weight, based on the propylene polymers used, of α-nucleating agents a process for producing them and their use.</p> |
