Abstract (en)
A spun yarn drawing apparatus by which yarns with a low boiling water shrinkage are obtained while surface temperatures of heat-setting heating rollers are restrained to be low is provided. The spun yarn drawing apparatus includes preliminary heating godet rollers 14 and 15 and heat-setting godet rollers 16 to 18 which are heating rollers rotating at higher yarn feeding speeds than the godet rollers 14 and 15. Onto each of these godet rollers 14 to 18, the yarns are wound at a winding angle of smaller than 270 degrees. In the heat-setting godet rollers 16 to 18, the yarn feeding speed of a roller on the downstream side is equal to or lower than the yarn feeding speed of a roller on the upstream side. Furthermore, the deceleration rate between the yarn feeding speed of the most upstream godet roller 16 in the yarn running direction and the yarn feeding speed of the most downstream godet roller 18 in the yarn running direction is 2% or higher.
