Tongchuan Chinese National Standard (CNS) A4 specification (210X297 mm) (read the precautions on the back of the page and fill in this page) — {ml pack ------ order — printed by the Central Standards Bureau of the Ministry of Economic Affairs, Shellfish Consumer Cooperative, A7 B7 V. Description of the invention (2) Heating the synthetic fiber yarn without touching the synthetic fiber yarn. More specifically, the yarn heating member is formed with a yarn heating channel that partially defines a yarn travel path between the yarn feeding device and the yarn false twisting device. When the synthetic fiber yarn passes through the yarn heating channel of the yarn heating member, the synthetic fiber yarn is heated by the yarn heating member. The yarn heating device further includes a plurality of yarn guide members located in the yarn heating channel of the yarn heating member in a spaced relationship from each other to guide the synthetic fiber yarn through the yarn heating channel of the yarn heating member unit. Such a yarn heating device for heating a synthetic fiber yarn is disclosed in, for example, US Patent No. 5 1 4 8 6 6 6 and includes a yarn heating member formed with a yarn heating channel and a yarn heating channel located in the yarn heating member. Multiple yarn guide members. Each yarn guide member is formed with a slit having an open end that allows synthetic fiber yarn to enter the slit and escape from the slit. When the synthetic fiber yarn is advanced in the yarn heating channel of the yarn heating member, the synthetic fiber yarn is passed through the slit of the yarn guide member and guided by the yarn guide member. For example, the slits of the yarn guide member extend in a straight line in the depth direction of the yarn heating channel, and each has a closed end spaced apart from the bottom wall portion of the yarn heating channel by the same distance. In addition, the slit of the yarn guide member is deflected from the center line in the cross section of the yarn heating channel. More specifically, the adjoining two-guide yarn members have their slits deflected from the center line of the yarn heating groove in opposite directions parallel to the width direction of the yarn heating groove, respectively. When the synthetic fiber yarn passes through the yarn heating channel of the yarn heating member, the synthetic fiber yarn is bent by a side wall portion of the slit of the yarn guiding member. This synthetic fiber yarn represented in the yarn heating channel has a plurality of curved portions equal to the number of the yarn guiding members, and thus follows a zigzag line in a parallel relationship with the surface of the bottom wall portion of the yarn heating channel. Advance. If the yarn heating equipment is applicable to the Chinese Standard for Storers (CNS) A4 (210X297 mm) on a musical scale (read the notes on the back and then fill out this page),-= * ο Central Standards Bureau of the Ministry of Economics only works Printed by the consumer cooperative A7 B7 V. Description of the invention (3) Preparation of the composition to advance the synthetic fiber yarn along the zigzag line 'It is possible to place the synthetic fiber yarn at a relatively low rate in the generally considered high rate range In the case of quasi-propulsion, the synthetic fiber yarn in the yarn heating channel of the yarn heating member is prevented from having harmful vibrations, such as a phenomenon called ballooning. Meanwhile, another yarn heating device for heating synthetic fiber yarns is disclosed in Japanese Patent Laid-Open Publication No. 6-4 9 7 2 4 or Japanese Utility Model Publication No. 5 9-7 3 3 7 8 which includes forming A yarn heating member having a yarn heating channel, and a plurality of yarn guiding members located in the yarn heating channel and each having a V-shaped recess that allows a synthetic fiber yarn to pass through. The V-shaped recesses of the yarn guide member each have a bottom wall portion in contact with the synthetic fiber yarn and each has a different depth. The depth of the V-shaped recess of the yarn guide member becomes larger as the yarn guide member moves away from the center point of the yarn heating member. This results in arching of the synthetic fiber yarn in an imaginary plane parallel to the depth direction parallel to the yarn heating channel. The fact that the yarn travel path is extended by the shape line. If the yarn heating device is constructed so that the synthetic fiber yarn is advanced along the bending line, the yarn heating device has the same advantages as the aforementioned device. That is, it is possible to prevent the synthetic fiber yarn in the yarn heating channel of the yarn heating member from having harmful vibrations when the synthetic fiber yarn is advanced at a relatively low rate level in a generally considered high speed range, This is called a balloon phenomenon, for example. However, the Diver__Tech _._ Boy Shame ... 1 卩 cover ^ set "has disadvantages, because if it is intended to advance the synthetic fiber yarn at a rate higher than a certain rate level, then the synthetic fiber yarn There is harmful vibration.

In addition, if the advance rate of the synthetic fiber yarn is increased to super? The 0 0 meter position criterion is on the yarn. The twist of the path exists A specific shock phenomenon occurs on the synthetic fiber yarn in the diameter portion. If the shock phenomenon occurs on the synthetic fiber yarn in the twisting path of the yarn traveling path, the tension of the synthetic fiber yarn changes extremely. In this case, It is difficult for the medium false twisting machine or the stretching and false twisting machine to increase its processing rate to a high speed level. Or it may allow the guide yarn to be weighed less than the conventional one under the intention of reducing the harmful vibration of the synthetic fiber yarn. The technical yarn heating equipment is arranged at regular intervals. In addition, the contact pressure between the synthetic fiber yarn and each yarn guide member can be increased to a certain level higher than the conventional technical yarn heating equipment described above with the same intention-level 0 but If the yarn heating device is constructed in this way, the yarn guide member is easy to fuzz synthetic fiber yarns. Therefore, the quality of synthetic fiber yarns The outline of the invention of low 0V and the huge g of the present invention is to provide a seed yarn heating device which reliably prevents harmful vibrations by improving the way that the yarn guide member is brought into contact with the synthetic fiber yarn.

The straight slits 3 1 a and 3 2 a of the yarn guide members 3 1 and 3 2 have different depths from each other. The depth of the straight slit 3 1 a or 32 a becomes larger as the straight slit 31 a or 3 2 a becomes farther from the center point of the yarn heating member unit 20 shown in FIG. 1 (a).

Therefore, the synthetic fiber yarn 1 has a plurality of contact surface portions each brought into contact with the straight slits 3 1 a and 3 2 a of the yarn guide members 3 1 and 3 2. Therefore, the number of the yarn guide members 3 1 and 32 is equal to the number of the contact surface portions of the synthetic fiber yarn 1. Although the synthetic fiber yarn 1 is bent by the yarn guide members 3 1 and 3 2, the synthetic fiber yarn 1 is kept away from the side wall portion of the yarn heating groove 20 a of the yarn heating member unit 20. The cross-sectional shapes of the wall portions of the straight slits 3 1 a and 3 2 a brought into contact with the contact surface portion of the synthetic fiber yarn 1 are similar to each other.

Description of the invention (16) It is not possible to obtain the fluff amount. From the experimental results shown in the table, it is obvious that the dyeing properties in Experiments 1 to 5 each using a total contact length of less than 3.5 mm were poor or in the case of a boundary line. The results of experiments 1 to 5 also show that the respective occurrence rates of the shocks are quite small. At the same time, each of experiments 6 to 9 using a total contact length of not less than 3.53 mm showed that the rate of occurrence of the shock exceeded 14 0 ni / mi n »In experiments 6 to 9, it was confirmed that no harmful vibration occurred in On the synthetic fiber yarn 1 between adjacent yarn guide members in the yarn heating channel 20a. In addition, good dyeing properties were confirmed in experiments 6 to 9. In the test 10 using a total contact length of 4 3 _ 3 7 mm, a large amount of fluffing occurred, so the quality of the synthetic fiber yarn 1 was reduced. In Experiments 6 to 9 using a total contact length of not more than 20.1 mm, the amount of fluff occurring in the synthetic fiber yarn 1 was not more than 0.33 points / kg. This indicates that the quality of the synthetic fiber yarn 1 in Experiments 6 to 9 was excellent. Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page). From the results of experiments 1 to 10 and the above description, you can understand that if the total contact length is less than 4 mm, 1 has a lack of uniform dyeing properties. In addition, the occurrence rate of the shock, that is, the treatment rate of the occurrence of the shock phenomenon on the synthetic fiber yarn 1, is quite low. As a result, the false twisting machine or the stretching and false twisting machine cannot stably process the synthetic fiber yarn 1 at high speed. Therefore, the minimum value of 'total contact length' is 4 m m, which is appropriate. On the other hand, if the total contact length greatly exceeds 20 mm, the rate of occurrence of the shock, that is, the processing rate of the occurrence of the shock phenomenon on the synthetic fiber yarn 1 will not increase much. Despite this, a large amount of fluffing occurred on the synthetic fiber yarn 1. Therefore, the synthetic paper size applies the Chinese National Standard (CNS) A4 specification (2 丨 0 乂 297 mm) -19-A7 _B7_ V. Description of the invention (17) The quality of the fiber yarn 1 is reduced. Therefore, the maximum value of the total contact length is appropriately 20 mm. The total contact length is preferably set to 7 mm. In this embodiment, 'because the total contact length representing the sum of the lengths of the contact surface portions of the synthetic fiber yarn 1 in contact with the yarn guide member is not less than 4 mm and not more than 20 mm, it is possible to prevent the synthetic fiber yarn 1 from lacking. Consistent dyeing properties. In addition, a large amount of fluff can be prevented from occurring on the synthetic fiber yarn 1. As a result, the quality of the synthetic fiber yarn 1 can be prevented from being lowered. On the other hand, as a result of setting the total contact length between 4 mm and 20 mm, the processing rate range in which no sharpening phenomenon occurs on the synthetic fiber yarn 1 can be extremely increased. This means that false twisting machines or stretch and false twisting machines can consider synthetic fiber yarns 1 at a significantly higher rate. 5 to 8, a second preferred embodiment of the yarn heating apparatus according to the present invention will be described below. The second preferred embodiment of the yarn heating device is constructed similarly to the first embodiment, except that a plurality of yarn guiding members 51 and a plurality of yarn guiding members 52 are provided. Therefore, the constituent elements of the second embodiment are denoted by the same reference numerals and symbols as those of the first embodiment, and repeated description and description are omitted. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page). The yarn guides 5 1 and 5 2 are located in the yarn heating channel 2 0 a of the yarn heating member unit 20, that is, In a spaced-apart relationship, they are located in the first yarn heating channel 2 1 a of the first yarn heating member 21 and in the second yarn heating channel 2 2 a of the second yarn heating member 22. More specifically, the yarn guide members 5 1+ and 5 2 are alternately arranged along the yarn heating groove 20 a in the yarn heating groove 20 a of the yarn heating member unit 20. The yarn guide member 51 functions not only to guide the synthetic fiber yarn 1 through the yarn heating member unit 20, but also to the paper size of the paper. Applicable to China National Standard (CNS) A4 specification (210X297 male; t) _ 20 _ A7 B7 V.

The yarn heating channel 2 0 a of the component unit 20 but also to prevent the synthetic fiber yarn 1 from being heated by the yarn in the yarn heating member unit 2 0 A mechanism that vibrates in the depth direction of the channel 20a. The synthetic fiber yarn 1 is bent by each of the yarn guide members 51 and has a plurality of contact surface portions that come into contact with the closed end of each of the straight slits 51a that is apparent from the previous description. Although the synthetic fiber yarn 1 is in contact with the yarn guide member 52, the synthetic fiber yarn 1 is not bent by each of the yarn guide members 52. Assuming that the yarn traveling path of the synthetic fiber yarn 1 is projected on an imaginary plane in the depth direction parallel to the upright line in FIG. 5, that is, the yarn heating channel 2 0 of the yarn heating member unit 20, the The yarn travel path is shown on the imaginary plane so as to extend along the arch line. The yarn guide member 51 printed by the staff consumer cooperative of the Central Standards Bureau of the Ministry of Economic Affairs is shown in FIG. 5 as a yarn heating channel 20 having a yarn heating member unit 20 near the center of the yarn straightly extending in the depth direction.

Further, the straight slit 5 1 a has a closed end 5 1 e for bending the synthetic fiber yarn 1 and an open end 5 1 d that allows the synthetic fiber yarn 1 to enter the straight slit 5 1 a and escape therefrom. The open end 5 1 d of the straight slit 5 1 a is defined by a pair of inclined wall portions 5 lb and 5 1 c. Therefore, the width of the open end 5 1 d of the straight slit 5 1 a is increased to be larger than that of the straight slit 5 The width w1 of 1 a is large w 2. Yarn guide member 5 2 is shown in Figure 6 as being near its own center.

In Fig. 7, the yarn travel path of the synthetic fiber yarn 1 in the yarn heating channel 20a is shown on the same imaginary plane not only as a whole extending along the arch line but also partially along the zigzag line. Figure 8 shows a second example of a modified yarn travel path. In Fig. 8, the yarn traveling path of the synthetic fiber yarn 1 in the yarn heating channel 20a is shown extending along a straight line on a virtual plane. As can be understood from the above description, the yarn guide members 5 1 and 5 2 can prevent the synthetic fiber yarn 1 from vibrating in the depth direction of the yarn heating channel 2 0 a and the width heating direction of the yarn heating channel 2 0 'a. It is possible to prevent harmful vibration from occurring on the synthetic fiber yarn 1 and to prevent the synthetic fiber yarn 1 from fluffing. In addition, all the yarn guide members 52 are set in the yarn heating channel 20a of the yarn heating member unit 20 so that the closed ends of the hook-shaped slits 52a of the yarn heating member unit 20 point toward the yarn heating member unit 20. The yarn heats the same side wall of the channel 20a.
