| titleOfInvention | Multistage drawing method of polyester fiber and apparatus therefor |
| abstract | (57) [Summary] [PROBLEMS] In direct spin drawing of polyester fiber, Provided is a method capable of preventing yarn sway occurring on a drawing roller, improving operational stability, and eliminating unevenness in heat treatment and stretching accompanying yarn sway and obtaining a drawn polyester yarn of excellent quality. SOLUTION: An undrawn yarn Y made of polyester is led to stretching roller groups (11) to (14) in which stretching rollers each including a pair of heating rollers are provided in multiple stages, and the stretching roller groups (11) to (11) to (14) Heat the unstretched polyester yarn Y on the turn by several turns to 20 turns, and draw the unstretched yarn Y in each stage with a draw roller (1 In a multi-stage stretching apparatus that stretches and winds between 1) and (14), a non-heated roller provided with a groove for regulating a yarn path near a first stretching roller (11) where the undrawn yarn Y is stretched first. (15) is installed at least, and the last-turned yarn is unheated by the non-heated roller (15). And a device for the multi-stage drawing of polyester fiber, characterized in that the yarn path is regulated by guiding the yarn to the groove. |
