MULTIPLE FIBER SPINNING APPARATUS AND METHOD FOR CONTROLLING SAME

摘要

Disclosed are a multiple fiber spinning apparatus and a method for controlling the same, which can spin multiple types of polymers at the same time to produce yarns having a variety of types of internal structures. According to the present invention, there is provided a multiple fiber spinning apparatus comprising: a spin block unit including gear pump portions for respective extruders and flow pipe portions for respective gear pumps of the gear pump portions, wherein each gear pump portion discharges, in the same or different amounts, a polymer material transferred from a certain extruder among said extruders, wherein each flow pipe portion delivers molten polymers; and a spinning nozzle unit having a plurality of spinning nozzles, wherein the spinning nozzles are connected to the respective gear pumps for the respective extruders through the respective relevant flow pipes so as to receive multiple types of molten polymers and discharges the molten polymers at the same time in order to spin yarn.
