Abstract
PURPOSE: In the drawing of tows, the draw ratios at the first and second steps are changed depending on the change in drawing speed to that the total draw ratio is kept constant, thus preventing the shift of the necking point caused by the change in heating time and producing the titled drawn yarn without yarn break.
CONSTITUTION: When a tow of undrawn polyester filaments is heated with heating rollers and drawn by a multistage method, the heating time for tow 7 at the first heating rollers 1 is changed depending upon the change in the drawing speed. Therefore, the rotation of the second heating rollers 3 is modified to change the draw ratio at the first step so that the position 10 of the necking point 6 may stay near the nipping point between the final roller 8 in the first roller group 1 and nip roller 2. Further, the rotation of the third heating rollers 4 is changed so that the total draw ratio becomes constant to change the draw ratios at the second and later steps, thus producing the objective drawn yarn.
