Description of the Related Art In a fiber production process, after a molten stock solution is formed into fibers of a predetermined shape by a spinning nozzle, oil is adhered to the fibers by using an oiling nozzle and sent to the next step. Here, the oil is adhered in order to smoothly guide the fibers in the subsequent steps and to prevent yarn breakage.

Further, fibers having a complicated shape such as a Y-shape instead of a circular cross section are used, and the fiber guiding speed is increased in order to increase the efficiency.

あった。As described above, in order to guide thin and irregularly shaped fibers at high speed, it is necessary to apply a predetermined amount of oil to the fibers 6 by the oiling nozzle 5. However, since the amount of oil attached varies depending on the guide speed of the fiber 6 and the amount of oil ejected, a predetermined amount of oil may not be attached to the fiber 6 in some cases. Therefore, when the amount of oil adhering to the fiber 6 is partially small, there is a possibility that a problem such as the fiber 6 being cut in a subsequent step may occur.

This makes it possible to detect the resistance value of the fiber to which the oil has adhered. Since the resistance of the fiber changes in accordance with the amount of oil adhering, the amount of oil adhering to the fiber can be detected by detecting the current value.

に電源２と電流計３を接続してある。As shown in FIG. 1, a fiber 6 coming out of a spinning nozzle 4 is guided by a guide surface of an oiling nozzle 5 and an oil supply opening formed in the guide surface. Oil is spouted from the mouth and adheres to the fibers 6. Thereafter, the fiber 6 to which the oil is attached is guided by an oil detecting member 1 made of a columnar conductive ceramic, and a power supply 2 and an ammeter 3 are connected to both ends of the oil detecting member 1.

６のオイル付着量を検出することができるのである。At this time, the fiber 6 itself has almost no conductivity, whereas the oil has conductivity.
The resistance value of the fiber 6 after oil attachment changes in accordance with the amount of oil attachment. Therefore, the oil detecting member 1
When the current value is detected by energizing both ends of the fiber, the apparent resistance value of the oil detection member 1 decreases and the current value increases as the amount of oil adhering to the fiber 6 to be guided increases. 6, the smaller the oil adhesion amount, the lower the current value. Therefore, if the current value is detected by the ammeter 3, the amount of oil adhering to the fiber 6 can be detected.

The range of the current value when an appropriate amount of oil is attached when a constant voltage of about the same is applied is set, and the fiber 6 is continuously guided while performing the application of the constant voltage and the detection of the current value. If a current value out of this range is detected, it is considered that the oil adhesion amount is abnormal, and the guidance of the fibers 6 may be stopped.

くするように制御すれば良い。Alternatively, although not shown, the oil supply amount of the oiling nozzle 5 can be controlled based on a signal of the current value from the ammeter 3. In this case, when the current value measured by the ammeter 3 decreases and the amount of oil adhering to the fiber 6 decreases, the amount of oil supplied to the oiling nozzle 5 increases, and conversely, the current value increases and the amount of oil adhering to the fiber 6 increases. If there is a large amount, control may be performed so that the oil supply amount of the oiling nozzle 5 is reduced.

Specifically, the power supply 2 and the ammeter 3 for guiding the fiber 6 after the oil is attached to the two oil detecting members 1 and 1 and for supplying a current between the oil detecting members 1 and 1 are provided. The current value when a constant voltage is applied between the oil detecting members 1 and 1 is detected by the ammeter 3. In this case, the current is detected by supplying electricity to the fibers 6 to which the oil is attached, and as described above, the resistance increases as the amount of oil attached increases, and the current decreases as the amount of oil attached decreases. Since the value decreases, the amount of oil adhering to the fiber 6 can be detected by detecting the current value by the ammeter 3.

As the material of the conductive ceramic, a conductive ceramic having a volume resistivity of 10 4 Ω · cm or less is used. That is, in order to detect the above-described current value, the oil detecting member 1 needs to have conductivity. However, a general metal material has a low wear resistance, so that the life is extremely shortened. Therefore, by using a conductive ceramic as the material of the oil detecting member 1, the above-described current value is detected, and the wear resistance is enhanced to extend the life.
