Abstract

PURPOSE: A spinneret, containing polymeric introductory holes having the top of horizontal square or hexagonal cross section and chamfered corners with a radius (R) thereof, having more spinning holes in the same surface area with little dead points, and capable of smoothing a polymeric flow.
CONSTITUTION: The horizontal cross sectional shape of polymeric introductory holes 3' constituting spinning holes 2' in a spinneret 1' is made square or hexagonal, and the corners are chamfered with a radius (A). The respective polymeric introductory holes 3' are in close vicinity to one another, and dead points for a molten polymeric flow are the shadowed parts (B) of small area between the corners of the polymeric introductory holes 3'. The flow of the molten polymer is smooth due to the chamfered corners with a radius (R) at the top.
