Abstract (en)
[origin: WO2018167304A1] A polypropylene composition is described having an MFI measured according to ISO 1133 for polypropylene of 1 to 3 g/10 min and a xylene soluble content in the range from 1 wt% to 4.5 wt% or 1.5 wt% to 4.5 wt%, which can be used to produce spun and drawn fibres having an average MFI measured according to ISO 1133 for polypropylene of 1 to 5g/ min, a xylene soluble content in the range from 1 wt% to 4.5 wt% or 1.5 wt% to 4.5 wt%, the spun and drawn fibres having an average elongation of at least 65% as measured by ISO 5079 with an adjusted testing speed of 80 mm/min, and/or an average tenacity/tensile strength of at least 56 c N/tex as measured by ISO 5079 with an adjusted testing speed of 80 mm/min.
