YARN PRODUCTION SYSTEM

An object of the present invention is to suppress the deterioration of a working environment of an operator in a winding chamber due to the high-temperature air in a spinning chamber, which flows into the winding chamber through a duct.A yarn production system 1 of the present embodiment includes a spinning apparatus 2 and a cooling apparatus 3 which are provided in a spinning chamber 101, a winding device 5 provided on a floor surface 102a of a winding chamber 102, a partition plate 40, and a duct 6. The duct 6 causes the spinning chamber 101 to communicate with the winding chamber 102, and extends downward in the winding chamber 102 so as to surround yarns Y. A working area W is provided below a lower end portion of the duct 6. The duct 6 has a yarn inlet 61 provided at the upper end portion of the duct 6 for allowing the yarns Y to be introduced into the duct 6, a yarn outlet 62 provided at the lower end portion of the duct 6 for allowing the yarns Y to be taken out from the duct 6, and an exhaust port 63 provided between the yarn inlet 61 and the yarn outlet 62 to be open to the winding chamber 102. A lower end of the exhaust port 63 is separated from the floor surface 102a of the winding chamber 102 by 5 meters or more.
