る溶融紡糸の加熱異重転付方法を提供するものである。Conventionally, after cleaning the metering pump, heat-resistant silicone oil, etc., was injected into the metering part and the heating operation was started. However, the silicone oil, etc. injected into the metering pump evaporated, and the gears could not rotate when the metering pump was turned on. Problems such as insufficient discharge occurred. In addition, if one metering pump for one spindle is replaced while the extruder is in operation, supplying polymeric substances to many spindles, the polymeric substance will melt during heating and flow into the replaced metering pump, and during spinning. A problem has arisen in which the extruder causes an instantaneous pressure drop. The present invention provides a heating different gravity transfer method for melt spinning that can eliminate the above-mentioned troubles when the metering pump is put into heating operation.

である。That is, in the present invention, when melt-spinning a polymer material,
This is a method for heating a molten iron yarn, which is characterized in that a metering pump to be newly installed is filled in advance with the polymer substance in the form of pellets or powder, heated, and started to operate.

定温度まで加熱昇温ごせて運転を開始するのである。In the present invention, after cleaning the metering pump, heat-resistant silicone oil or the like is injected into the metering section, the metering pump is filled with a pellet-like or powdered polymer substance in advance, and then installed, and then heated to a predetermined temperature. Start driving.

充填作業の容易さあるいは加熱昇温時の溶融速度の点等
で好ましい。The size of the pellet-like or powder-like polymer substance to be filled into the metering pump depends on the capacity of the metering pump, but in the case of ordinary brands of melt spinning, it is about 0.5 to 5 columns in diameter and 0.5 to 5 columns in length. Powder in the form of pellets or smaller is used, but
It is preferable in terms of ease of filling operation and melting rate during heating and temperature rise.

検査するのである。In addition, the pellet-like or powder-like polymeric substance to be filled into the metering pump is of the same type as the polymeric substance to be melt-spun, and contains additives and
For example, it is preferable that the same and the same amount of the matting agent and the like be added, and the amount charged into the metering pump is preferably 40% or more of the volume of the melt flow section of the metering pump.
With heating operation, the metering pump is replaced, the metering pump is heated to a predetermined temperature, and then the rotational condition of the metering pump is checked while running idly, and then the molten polymer substance is fed and the metering accuracy is checked.

付した結果次の表のごとくであった。According to the present invention, the metering pump does not become unable to rotate even in the heated state, and troubles caused by insufficient discharge at the initial stage of melt spinning can be completely eliminated. Example: In a device that extrudes nylon 6 at 26,000 yen with an extruder, calculates it with a metering pump, and threads the yarn through a nozzle, silicone oil is simply injected into the metering pump when replacing the metering pump. and silicone oil, and a nylon 6 pellet shape (diameter 1
Wind? , length 1 sail) filled with 50% of the volume of the melt flow section of the metering pump was installed to increase production by 10 each, and heating operation was performed.The results are as shown in the following table.
