Abstract
PURPOSE: Filaments, immediately after spun, is rapidly cooled and collected near the spinneret to give directly melt spun and undrawn fibers satisfying a specific equation, which is then oriented and drawn, thus producing title fibers with reduced fluffs and denier uneveness.
CONSTITUTION: For example, filaments 7 extruded from spinneret 5 are rapidly cooled just under the spinneret 5 by blowing cooling air 10 and collected by guide 8 that is located releatively near the spinneret 5, resulting in the formation of undrawn continuous filaments of thermoplastic polymer satisfying equations I and II, in which D is denier of filament; X is maximum draw ratio in %]. Subsequently, the filaments are drawn to form the objective filaments with a filament denier of 0.05W0.30 denier. The above undrawn continuous filaments are made by using a spinneret 5 with a cross-section area per orifice of less than 3.5×10-4 cm2 and keeping the atmosphere of 1W3 cm area under the spinneret 5 to 200°C and collecting at the position of 10W250 cm under the spinneret 5.
