Abstract:
Processes for making high-performance polyethylene multi-filament yarn are disclosed which include the steps of a) making a solution of ultra-high molar mass polyethylene in a solvent; b) spinning of the solution through a spinplate containing at least 5 spinholes into an air-gap to form fluid filaments, while applying a draw ratio DR fluid ; c) cooling the fluid filaments to form solvent-containing gel filaments; d) removing at least partly the solvent from the filaments; and e) drawing the filaments in at least one step before, during and/or after said solvent removing, while applying a draw ratio DR solid  of at least 4, wherein in step b) each spinhole comprises a contraction zone of specific dimension and a downstream zone of diameter Dn and length Dn with Ln/Dn of from 0 to at most 25, to result in a draw ratio DR fluid =DR sp *DR ag  of at least 150, wherein DR sp  is the draw ratio in the spinholes and DR ag  is the draw ratio in the air-gap, with DR sp  being greater than 1 and DR ag  at least 1. High-performance polyethylene multifilament yarn, and semi-finished or end-use products containing said yarn, especially to ropes and ballistic-resistant composites, are also disclosed.

Claim (Index 15):
The ballistic-resistant sheet of  claim 1 , further comprising a third layer and a fourth layer each comprising the high-performance polyethylene multifilament yarn, wherein the filaments of the multifilament yarn in the third layer and the fourth layer are spread uni-directionally within each of the third and the fourth layers, and wherein the direction of the filaments in each layer is rotated with respect to the direction of the filaments in an adjacent layer.
