Abstract

PURPOSE: To obtain a spinneret having a high flatness of the spinning surface and compressive strength without causing broken fibers, by perforating many small holes through a material for a spinneret, e.g. a flat thin disc or thin disc plate with a flat recess, and finishing and molding the plate into the desired form of a spinneret.
CONSTITUTION: A material for a spinneret consisting of a flat thin plate 5 or a thin disc plate with a flat recess is perforated with spinning holes 8 consisting of many polymer introductory ports 6 amounting to several thousands and small extruding holes 7 communicating with the ports 6 are radially and coaxially at regular intervals. The perforated plate is then finished and molded into the desired form of a spinneret to give the aimed spinneret 11. After boring the spinning holes 8, a spinneret 13 having a flange 9 and a stepped part 12 and further a flat recess 10' having a depth of several cm from the stepped part 12 may be obtained.
