ABSTRACT:
The invention relates to a highly oriented polyolefin fiber containing polyolefin with an intrinsic viscosity of at least 5 dl/g, which fiber has a tensile strength of at least 26 cN/dtex and a modulus of tension of at least 700 cN/dtex, a process for the preparation thereof and the use in ropes or anti-ballistic shaped articles. The invention also relates to improved ropes and anti-ballistic shaped articles. The highly oriented polyolefin fiber according to the invention has improved properties in applications such as, in particular, anti-ballistic shaped articles since the fiber contains 0.05-5 wt. % of a solvent for the polyolefin (relative to the total fiber weight).
