摘      要：According to the characters of poly-ether-ether-ketone (PEEK) plastic, the spinnerets with three kinds of different structure were designed. The effects of spinneret structure on the melt spinning conditions, melt flow instability of the screw extrusion, and the performance of PEEK fibers were studied. The results show that the appropriate screw extrusion temperature is 370 385℃. The PEEK fibers extruded using the spinnerets with L/D=6, 8holes and 0.5mm in diameter have better performances. The performances of PEEK fibers are related to the dia- meter of the spinneret hole. Increasing the L/D value of the spinnerets can not always improve the surface quality and the performances of PEEK fibers. The extrusion pressure is about 50% of that of the spinneret with 12holes and 0.3mm in diameter.
