Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a false-twist texturing method capable of eliminating yarn breakage factors caused by twisting polylactic acid fibers susceptible to damages due to friction and heat by a friction-type false-twisting device and high-temperature heating of the above fibers by a primary heater. SOLUTION: This false-twist texturing method for yarns comprising polylactic acid fibers involves using a false-twisting device 8 of nipping-type and setting a heating temperature by a primary heater 5 at
