摘要： PROBLEM TO BE SOLVED: To provide a method for producing a thermoplastic synthetic fiber having improved productivity by preventing spinning yarn breakage caused by accumulation of deposit on the surface of a godet roller.
SOLUTION: A thermoplastic synthetic fiber is produced by oiling a melt-spun yarn, entangling the yarn, drawing the yarn through a godet roller, and heat-treating and winding the product. In the process, a yarn restriction guide placed immediately before or after the drawing zone is reciprocated in a direction of the rotary axis of the godet roller, the reciprocating motion satisfies the formula Y≤XP, when Y is the reciprocation width of the yarn, and XP is the distance (mm) between the yarns, and the yarn contacting time at the distance of 1/10 from the turning point in one traverse reciprocation motion of the yarn is 20% or less.
