Abstract
PURPOSE: The title spinneret designed to spin fibers uniformly and steadily and to attain uniform extrusion from a number of orifices, wherein the inside diameters of holes comprising the tips of pipes are narrowed.
CONSTITUTION: The straight pipes 4 having no protrusions for support are inserted into the holes having the narrow parts 5, which are not in contact with the pipe walls 4. The polymer A for the island component is fed from the holes 1; the polymer B for the sea component, from the space 7. The flow of the polymer B is regulated by the annular parts between the holes 6 and pipes 4 to enclose the polymer A well. The narrow parts 5 can be readily manufactured by machining a rigid plate, are uniform and of high accuracy, will not bend like a pipe, and act as supporting parts to prevent the bending of the pipes 4.
