[0002] Polyester has excellent properties such as light weight and moisture absorption and perspiration wicking, and is becoming more and more popular. Twisting is the process of twisting multiple strands of monofilaments into one strand using rotary motion to fix the longitudinal connection between the fibers. Usually, a polyester yarn twisting device is required.

[0003] After searching, the Chinese utility model patent with authorization announcement number: CN219568159U discloses a polyester yarn fine twisting device. Although the above device allows multiple strands of polyester yarn to pass through the inner ring of the guide cylinder through a blocking piece, the polyester yarn can pass through quickly and ensure that the multiple strands of polyester yarn are twisted stably, but when the twisted polyester yarn is collected, the polyester yarn will be entangled and accumulated outside the take-up roller, so that the take-up roller cannot be fully used, resulting in poor take-up effect of the take-up roller and affecting the quality of the take-up.

[0004] Therefore, we propose a polyester yarn fine twisting device to solve the above problems. Utility Model Content
