GEL SPUN POLYETHYLENE FIBER |
摘要 |
The invention relates to a gel-spinning process for producing UHMWPE fibers, said process comprising the steps of a) feeding a slurry containing UHMWPE and a spinning solvent to an extruder; b) converting the slurry in the extruder into a solution of UHMWPE in the spinning solvent; c) spinning fluid UHMWPE fibers by passing the solution of step b) through a spinning plate containing a plurality of spin holes; d) cooling the fluid UHMWPE fibers to form gel UHMWPE fibers; e) removing at least partly the spinning solvent from the gel UHMWPE fibers; and f) drawing the UHMWPE fibers in at least one drawing step before, during and/or after removing the spin solvent characterised in that the spinning plate having at most 6 spin holes per cm2. |
