Abstract

PURPOSE: To obtain the titled nonuniform fibers having a noncircular cross section and change in the cross section in the long direction thereof, by extruding a mixture of a molten thermoplastic polymer with an infusible fine powdery material having a specific particle size through a special spinneret, and cooling the extruded fibers.
CONSTITUTION: A mixture melt of a molten thermoplastic polymer, e.g. polypropylene, with an infusible solid fine powdery material, e.g. calcium carbonate, is extruded through a spinneret in which a melt extruded through recessed areas present between discontinuous protruding areas provided between the adjacent fine gaps on the extruding side is capable of mutually communicating with a melt extruded from the adjacent fine gaps. A cooling fluid is then fed to the extruding surface and the vicinity thereof, and the melt is taken off while cooled and changed into many separated fibrous fine streams and coagulated to give the aimed fibers, having a noncircular cross section and change in the cross section in the long direction, and containing the fine powdery material passing through a 20-mesh screen.
