Embodiment and comparative example
With the yarn road based on arcuate fashion shown in Fig. 2 (a), in conjunction with the Z-shaped mode shown in last Fig. 2 (b), change and guide member 31, the section configuration of 32 walking tow contact portion and size and Z-shaped amount, slowly change guide member 31,32 with the summation of the contact length of tow, during the experiment of the generation speed that fluctuates simultaneously, chromatic degree of irregularity and fluffing generating capacity, can obtain the result shown in the following table.And employed guide member 31,32 contacts section basic configuration partly as shown in Figure 3 with the walking tow in this experiment.
The kind of tow 1-processing back dawn number is that the radical of 75 DENIER, long filament is 36 gathering
The fat long fiber; The the 1st and the 2nd tow heating tank 21a, the length of 22a is than-1: 1.9; Heater total length (the LH)-1.1m of calandria 21,22 (on the downstream of upstream extremity to the 2 tow heating tank 22a of the 1st tow heating tank 21a); The heating-up temperature of the 1st calandria 21-500 ℃; The heating-up temperature of the 2nd calandria 22-260 ℃; The number-11 of the 1st guide member 31 in the 1st tow heating tank 21a; Draw ratio-1.65; The number-11 of the 2nd guide member 32 in the second tow heating tank 22a; Draw ratio-1.65; False-twisting device form-3 friction disc (disk constitutes 1-7-1).Table
| Thread-carrier contact length summation (mm) | Fluctuation generation speed (m/ branch) | Chromatic degree of irregularity | The fluffing generating capacity (individual/kg) | |
| 1 2 3 4 5 | 0.37 0.85 1.27 1.79 2.33 | 1160 1218 1290 1280 1370 | × × × △ △ | Can not process and to process 0.20 0.22 0.27 |
| 6 7 8 9 | 3.53 10.53 11.40 20.10 | 1420 1440 1420 1430 | 0 0 0 0 | 0.25 0.22 0.30 0.33 |
| 10 | 43.37 | 1455 | 0 | 1.43 |
Be that the tow of using the speed of dividing than the low 100m/ of fluctuation generation speed to process is estimated about chromatic degree of irregularity in the table; And be to divide the tow process to estimate with winding speed 1200m/ about the fluffing generating capacity.
Can clearly be seen that in the experimental example 1～5 (comparative example) of guide member contact length summation, chromatic non-uniform phenomenon is arranged from the result, can not get the tow of fine quality, and fluctuation generation speed is low less than 3.53mm.To this, in guide member contact length summation reached experimental example 6～9 (embodiment) more than the 3.53mm, fluctuation generation speed reached more than 1400m/ divides.In addition, in the experimental example 6～9 here, in the 1st calandria 21 and the 2nd calandria 22, the abnormal vibrations of tow 1 can not take place between adjoining guide member respectively, it is good that dyeability also becomes.
In addition, reached in the experimental example 10 (comparative example) of 43.37mm in the summation of guide member contact length, fluffing significantly takes place, and can not get the tow of fine quality; Comparatively speaking, in the experimental example 6～9 (embodiment) of guide member contact length summation below 20.10mm, the fluffing generating capacity be controlled to 0.33 (individual/kg) below, can get the tow of fine quality.
Like this, if chromatic non-uniform phenomenon can appear in the discontented 4mm of guide member contact length summation, the tow quality significantly descends; Simultaneously, fluctuation generation speed is low, can not carry out High-speed machining.Thereby, must keep guide member contact length summation among the present invention more than 4mm.In addition, if guide member contact length summation more than 4mm.In addition, if guide member contact length summation substantially exceeds 20mm, fluctuation generation speed no longer is greatly improved; On the contrary, because fluffing takes place significantly, the tow quality is low, so in the present invention, guide member contact length summation is decided to be below the 20mm.
As above explanation, in the present invention, tow 1 is limited in the scope that 4mm is above, 20mm is following with the summation of the contact length of the 1st and the 2nd guide member 31,32 contact respectively, therefore, can prevent owing to the inhomogeneous quality decline problem that causes with the generation fluffiness of dyeing; Simultaneously, can expand the operating range that does not take place to fluctuate significantly.
Fig. 4 and Fig. 5 show desirable other embodiment of example of the present invention.
And, under this example, be disposed at guide member in the tow heating tank except that shape, other and the foregoing description are roughly the same, and in the track route of the synthetic fibre tows of false twisting or draw false twisting processing, from the false-twisting device beginning, twisting trace back and twisting area between in heat tow.And, on Fig. 4 and Fig. 5 unshowned guide member around constitute with the symbol of the foregoing description consistently, the spy is illustrated.
In Fig. 4 and Fig. 5, the 51st, be disposed at respectively through 1 tow heating tank 21a, with the 2nd tow heating tank in, at each tow heating tank 21a, in the prescribed limit of the groove width direction (laterally) of 22a (the guide seam 51a that talks about later) tow 1 is led, limit the restriction rolling guide member of the lateral oscillation of tow simultaneously; 52 then be with respect to this rolling restriction guide member, at the draw direction of each tow heating tank 21a, 22a every interval with regulation, dispose alternately with guide member 51, in the prescribed limit (the restriction pitching guiding ditch 52d that the back will be talked about) of the groove depth direction (vertically) of each tow heating tank 21a, 22a, tow 1 is led, limit the restriction pitching guide member of the oscillation in the pitch mode of tow simultaneously.These restriction rolling guide members 51 and restriction pitching guide member 52 along tow 1 interior between aforementioned twisting area, tow 1 is walked by aforementioned arcuate fashion.
Restriction rolling guide member 51, as shown in Figure 4, central portion at the width of tow heating tank 21a, 22a, raw silk rings bundle heating tank 21a, degree of depth h1, the guide slotted section 51a that width is W1 that the depth direction of 22a extends, also have simultaneously from what the throat width W1 of guiding slit 51a expanded stor width W 2 and widen chamfered portion 51b, 51c.
On the other hand, as shown in Figure 5, restriction pitching guide member 52 has at tow heating tank 21a, the central portion of the width of 22a, in tow heating tank 21a, the distortion slit 52a of portion that the depth direction of 22a extends, and the throat width of the 52a of this slit portion equates with the throat width W2 of guide slotted section 51a.In addition, this restriction pitching guide member 52 also has the 1st inclined plane part 52b that widens the same gradient of inclined plane part 51b with restriction rolling guide member 51, and has the 2nd inclined plane part 52c that extends out than the steeper inclination angle of this chamfered portion 52b.These the 1st inclined plane part 52b and the 2nd inclined plane part 52c then are when tow 1 is directed to the position of diagram degree of depth h3 when entrying, and tow 1 only are offset the sloping portion of ormal weight from the center of guide slit 51a.Below the 2nd inclined plane part 52c, form restriction pitching guiding yarn slot part 52d again, when tow 1 is directed to degree of depth h3 when entrying, because the effect of tension force, tow 1 splits away off and imports in the restriction pitching guiding ditch 52d of portion from the lower end of the 52c of the 2nd chamfered portion, adds the groove width direction center of arriving again (center of guide slit 51a) again.Like this, be imported into tow 1 among the restriction pitching guide slot part 52d and promptly limited its moving of above-below direction by restriction pitching guide member 52 with from downside (bottom land one side) by restriction rolling guide member 51 from upside.Here, because suitably set depth h1 and h2 not only can take arc walking, also can take the to quarrel arc walking in same plane shown in 6 and the combination of Z-shaped walking, or linear shown in Figure 7 is walked.
Like this, owing to wave (line waves) not only at tow heating tank 21a during tow 1 walking, the groove width direction of 22a and limit at the above-below direction guide member 51,52 of groove depth just can prevent the nuisance vibration and the whirling of tow 1 effectively.In addition, in the example of this example, because tow 1 moves to groove width direction center because of tension force effect meeting comes off from the bottom of the 2nd inclined plane part 52c of restriction pitching guide member 52 when entrying, so, although limiting pitching guide member 52 fixed configurations in tow heating tank 21a, in the 22a, entry and also carry out easily.And, the gyratory directions of the tow 1 that is formed by the tracing back of twisting of coming from false-twisting device is, facing to the upper wall surface 52e of the restriction pitching guide slot part 52d that limits pitching guide member 52, be the direction of the arrow A of Fig. 5, it is optimal that tow 1 does not get over the facial 52e of upper wall.
Fig. 8 shows another embodiment of the desirable example of the present invention.
And, also be that formation same as the previously described embodiments, not shown adopts symbol same as the previously described embodiments in the present embodiment, it is described.
On Fig. 8, the 61st, have the 1st tow heating tank that the tow 1 between the twisting area that has illustrated in the above-described embodiments stretches (though there is not tow heating tank 21a in detailed icon and the foregoing description, 22a is same) the 1st cut apart calandria, in aforementioned the 1st tow heating tank, be equipped with a plurality of the 1st guide members 71; The 62nd, have the 2nd of the 2nd tow heating tank (figure is detailed) that is arranged in from the downstream of the 1st tow heating tank tow trend and cut apart calandria, in aforementioned the 2nd tow heating tank, be equipped with a plurality of the 2nd guide members 72 by predetermined space.In addition, the configuration space of the 1st guide member 71 is average narrower than the configuration space of the 2nd guide member 72.
The interval of the 2nd guide member 72 in tow 1 direction of travel is P1 at the setting of the regulation field A1 of the upstream side of aforementioned the 2nd tow heating tank; And at the setting P2 of its field, downstream A2 than P1.That is, also be that the disposition interval of the 2nd guide member 72 has narrowed down at upstream side regulation neighborhood A1 than the A2 in downstream field, the 2nd guide member 72 is configured with different intervals.
Like this, produce the nuisance vibration of tow 1 owing to prevented tow 1 middle part between twisting area, make the temperature of the tow 1 in downstream between twisting area be difficult for forming inhomogeneous, the temperature stabilization of the heater outlet of tow 1 can carry out good heat treatment.
And, the action effect of this example, particularly cutting apart the identical of calandria 62 by the 1st heating-up temperature and the 2nd of cutting apart the tow 1 that calandria 61 produces or than it under the low situation, or stopped the 1st and cut apart calandria 61 and, be very significant only by under the situation of opening calandria 62 runnings on the 2nd minute.
