The twist applied by the twisting device and going back along the yarn is heat-set, and then untwisted when passing through the twisting device to obtain a false twisted yarn. Many suggestions have been made.

ヒータが使用されている。Recently, the heating device has been heated to a high temperature (a temperature higher than the melting point of the yarn, preferably 400 ° C. or higher) to heat the yarn in a non-contact state.
That is, the processing speed of the recent draw false twister has been increased, and a high-temperature non-contact type short heater has been used instead of the conventional low-temperature contact type heating device.

As a countermeasure, it is conceivable to use a material having a high melting point, such as brass, stainless steel, or ceramics, as a material of the heating device used at a high temperature as described above. Further, as the far-infrared heater, it is conceivable to use a material made of far-infrared radiation ceramic or to coat the surface with ceramic.

When the yarn to which such oil agent is applied is heated to a high temperature as described above. , The oil agent evaporates and decomposes in the heating device (heater). The heater material is easily corroded due to the vaporized oil and the high temperature. As a countermeasure, the heater material needs to endure it.

When used as a high-temperature heater as described above, the temperature distribution in the longitudinal direction of the heater becomes extremely non-uniform, and the temperature difference between the temperature of the heating plate and the sheathed heater as a heat source for heating the heating plate increases. Since the sheathed heater is heated to an extremely high temperature in order to heat the plate to a desired temperature, there is a problem that its life is shortened. Further, stainless steel has poor machinability even in the production of a heating device.

Heating plates 11 and 2 are formed by sheath heaters 12 and 22 extending longitudinally in a heating slope along the yarn path.

る。When the heating plates 11 and 21 are heated, the groove 11a in which the yarn travels is usually located at a midpoint position in the longitudinal direction (up and down in FIG. 1) of the heating plate (ie, an intermediate position in the longitudinal direction of the heater). , 21a are measured by the temperature sensors 13 and 23, and the temperature of the heating plate is controlled to a predetermined set temperature. In this case, the set temperature of the first heater of the false twisting machine is such that the yarn temperature at the heater outlet is:
For example, the temperature is selected to be a predetermined temperature such as 220 ° C.

Is measured in FIG. 4). In FIG.
The broken line shows the case where the heating plate is made of brass, and the one-dot chain line shows the case where the heating plate is made of stainless steel.

ツキは増加する。Since the heating device is open up and down in the longitudinal (vertical) direction, heat is radiated from here by convection and the like, and therefore the temperature of the heating plate at the upper and lower positions in FIG. 4 is lower than the temperature at the center. In addition, when the set temperature is increased, the variation in the temperature distribution increases.

差異に起因するものと本発明者は考えている。The difference between the temperature distribution state of the heating plate made of brass shown by the broken line and the temperature distribution state of the heating plate made of stainless steel shown by the dashed line is caused by the difference in the thermal conductivity of the heating plate material. The inventor thinks that.

大きくなる。In such a heater, in order to be able to perform the yarn hooking, which is a feature of the high-temperature heater, that is, the yarn fused to the yarn guide at the time of yarn breakage can be melted and removed in a short time, the fused yarn is used. Is heated to a sufficiently high temperature (for example, 320 ° C. or higher, preferably 400 ° C.
C. or higher), that is, it is necessary to increase the set temperature of the heating plate, and accordingly, the temperature difference between the set temperature of the heating plate and the sheathed heater as a heat source for heating the heating plate increases.
【００３２】また、この場合にヒータ出口部での糸条温

Similarly, the set temperature of the heating plate and the heat source for heating it The temperature difference of the sheathed heater becomes large.

ることは好ましくない。As described above, since the sheathed heater is heated to an extremely high temperature in order to heat the heating plate to a desired temperature, there is a problem that its life is shortened. In addition, there is a concern that running the yarn in a heater having a non-uniform temperature distribution may adversely affect the yarn quality. Therefore, it is not preferable to use stainless steel for the heating plate of the high-temperature heating device aimed at by the present invention.

うである。On the other hand, as can be seen from the dashed line in FIG. 4, when brass having a high thermal conductivity (0.26 Cal / cm.s..degree. C.) is used for the heating plate, the problem of non-uniform temperature distribution is a problem. Virtually gone. According to the study of the present inventors, stainless steel has the above-mentioned problem because its thermal conductivity is about 1/10 that of brass, and the thermal conductivity is about １ ／ to ３ of the thermal conductivity of brass. , It seems that the problem of non-uniform temperature distribution hardly occurs. According to the inventor's experience, it seems that the thermal conductivity is preferably 0.10 Cal / cm · s · ° C. or more.

Since the corrosion in this case is remarkable, it cannot be used as a high-temperature heater as in the present invention.

In this case, the oil agent evaporates and decomposes in the heating device (heater). The heater material is easily corroded due to the vaporized oil and the high temperature. As a countermeasure, the heater material needs to endure it.

The process of immersing the sample in a stock solution of a polyester fiber, which is a typical synthetic fiber, for treatment of a polyester yarn for about 10 seconds, and then maintaining the sample in an atmosphere at 560 ° C. (baking) is repeated 36 times within 200 hours. The weight of the sample before treatment is W 0
And then, the weight after the treatment as W 1, weight change before and after the treatment (W 1 -W 0) of the absolute value of pretreatment weight (W 0) with the value obtained by dividing the percentage [100 × (W 1 -W 0 ) / W 0 )] is the weight change rate. The weight change rate is an index for determining corrosion resistance, and it can be said that the smaller the weight change rate, the better the corrosion resistance.

ての問題はない。Of the experimental results shown in Table 1, Sample A had a zero aluminum content in the copper alloy, and the weight change rate (* 1 in Table 1) for this sample was extremely large as described above. Since it is not necessary to measure, it was omitted. In Table 1, samples D, F, and G were baked up to 16 times, respectively, but the weight change during that time was not much different from samples E and H. , Discontinued further pickling experiments on G,
Therefore, the weight change rates of them are not described (* 2 in Table 1). However, it is considered that there is no problem even if these samples D, F, and G are used as a heating plate of a heating device for a synthetic fiber yarn. Also, copper alloy has a high melting point,
There is no problem with using a heating plate used at 400-800 ° C.

That is, if the addition amount of aluminum is more than 6% and less than 8%, extrusion molding becomes difficult. Therefore, it is important to find a balance between the amount of aluminum added and the formability of the heating plate.
