Abstract

PURPOSE: To obtain a filament, capable of giving an ultrafine fiber on peeling and division after forming into a product with a good fiber preparation efficiency, by finely dividing different types of polymer flows independently and respectively, arranging different types of polymer flows annularly to extrude a filament without the hollow part.
CONSTITUTION: Different polymer flows A and B are distributed by the first distributing plate 1' and divided into independent polymer flows corresponding to the respective segments after the division by inflow paths 5 and 6. The two polymer flows A and B are joined by inflow paths 5' and 6' in the third distributing plate 3' annularly into a shape (I), formed into an annular composite flow (II) of the side- by-side type and sent to a spinneret plate 4'. The two polymer flows A and B are then formed into a shape (III) without a hollow part after the conical protrusion 8 in the spinneret plate 4' and spun into a filament.
