Abstract: The invention relates to a process for making high-performance polyethylene multi-filament yarn comprising the steps of making a solution of ultra-high molar mass polyethylene in a solvent; spinning of the solution through a spinplate containing a plurality of spinholes into an air-gap to form fluid filaments, while applying a draw ratio DRfluid; cooling the fluid filaments to form solvent-containing gel filaments; removing at least partly the solvent from the filaments; and drawing the filaments in at least one step before, during and/or after said solvent removing, while applying a draw ratio DRsolid, wherein in a draw ratio DRfluid=DRsp×DRag of at least 50 is applied, wherein DRsp is the draw ratio in the spinholes and DRag is the draw ratio in the air-gap, with DRsp greater than 1 and DRag at least 1. The invention further relates to a spinplate having spinholes of specific geometry.

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).
