Highly oriented polyolefin fibre |
(57) The invention relates to a highly oriented polyolefin fibre containing polyolefin
with an intrinsic viscosity of at least 5 dl/g, which fibre 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 fibre according to the invention has improved properties
in applications such as, in particular, anti-ballistic shaped articles since the fibre
contains 0.05 - 5 wt.% of a solvent for the polyolefin (relative to the total fibre
weight).
