Abstract
PURPOSE: To prevent a yarn from drawing and damaging in the spinning step and wind up the uniform yarn into a package stably, by melt spinning a thermoplastic polymer at a high speed, applying an oiling agent to the resultant filamentary yarn at a specific position, and winding the oiled filamentary yarn.
CONSTITUTION: A molten polymer extruded through spinneret 1 is cooled and solidified by a cooling air current in one direction from a chimney (stack) 2 and oiled and then wound at a speed of 2,500m/min or higher to give a filamentary yarn of fineness per filament of 1W20 deniers. In the step, the oiling position is made to satisfy the following relations: 1/4R≤X≤2R [R (cm) is the diameter of the spinneret, X (cm) is the distance from the central perpendicular line of the spinneret 1 to the oiling position]; 1.092lnd-1/5≤L≤1.092lnd+5/3 [d (denier) is the fineness per filament of the undrawn yarn; L (m) is the distance from the surface of the spinneret 1 to the oiling position]; and 1.0≤L simultaneously.
