PROBLEM TO BE SOLVED: To provide a spinning drawing device capable of obtaining a yarn with a low boiling water shrinkage while keeping a surface temperature of a heating roller for heat setting at a low level.SOLUTION: A spinning drawing device comprises: godet rollers 14, 15 for preheating; and godet rollers 16 to 18 for heat setting, which are heating rollers with faster yarn feeding speed than that of the godet rollers 14, 15. A yarn is wound around each of the godet rollers 14 to 18 at a winding angle less than 270 degrees. For the godet rollers 16 to 18 for heat setting, a yarn feeding speed of the roller on the downstream side is the same as or less than that of the roller on the upstream side. A reduction ratio of the yarn feeding speed relating to the godet roller 16 in the most upstream in a yarn running direction and the godet roller 18 in the most downstream in the yarn running direction is 2% or higher.SELECTED DRAWING: Figure 3 |
