Abstract (en)
An object of the present invention is to suppress airflow in the vicinity of filaments from being disturbed.A melt spinning system 1 comprises a spinning unit 2 which spins the filaments out, a cooling unit 3 which cools the filaments, and an exhaust unit 4 which includes a waste channel 30 sucking and discharging the gas being generated from the filaments. The exhaust unit 4 includes a sucking unit 31 which includes a suction port of the gas, a duct 32 which is placed downstream of the sucking unit 31 in the gas discharge direction, an aspirator 33 which is placed downstream of the duct 32 and sucks and discharges the gas, a connecting pipe 34 which is placed downstream of the aspirator 33 and connected to an intermediate part of a fixed pipe 100 being fixedly provided, and an inflow suppressor 70 which suppresses inflow of the gas into the connecting pipe 34 from the fixed pipe 100.
