Stomata 72 and form internal screw thread (not shown) on peripheral wall 71, and can be screwed togather for screw (not shown) etc..
Pipeline 33 is attached for that will surround component 31 with suction pump 34.There are two upstream portion 81 and one for the tool of pipeline 33
A downstream portion 82.Encirclement component is separately installed in two upstream portions 81 (upstream portion 83 in left side and the upstream portion 84 on right side)
31 two the 2nd component 31b.Two upstream portions 81 connect with the upstream side end of downstream portion 82 and are collaborated.Under downstream portion 82
Trip side end is connect with suction pump 34.As a result, in the state that the 2nd component 31b for surrounding component 31 is separated from the 1st component 31a,
The 2nd component 31b can be made relative to the 1st component 31a activity.
Suction pump 34 is used to attract from the inside of air exhaust loop 32 gas of discharge monomer.As an example, suction pump 34 uses
Tap aspirator.Thereby, it is possible to generate small suction pressure (such as -5Pa), and the gas of monomer can be made to be dissolved in water and arrange
Out.In addition, suction pump 34 is not limited to tap aspirator, such as air blower also can be used etc..
It is single by the attraction of suction pump 34 when suction pump 34 acts in there is the exhaust apparatus 4 constituted above
The gas of body passes sequentially through the interior of multiple gas vents 72 of air exhaust loop 32, the inner space 44 of encirclement component 31 and pipeline 33
Portion and be attracted discharge (referring to Fig. 3 arrow).
Herein, when spinning thinner long filament f, when the gas of monomer is sucked out from the inside of air exhaust loop 32, when from spray
When silk head 13 spins air turbulence near next long filament f, silk thread swing can be generated, silk thread quality is easily reduced.For example, when from
When gas is sharp discharged in the inside of air exhaust loop 32, air-flow is easy disorder near long filament f.In addition, when in a part of air exhaust loop
In 32 gas by sharp attract etc., between multiple air exhaust loops 32 gas traffic attraction generate deviation when, the swing mode of silk thread
Deng being easy between multiple air exhaust loops 32 to become different, silk thread quality is easy to produce deviation.Therefore, thinner long filament f is being spun
In the case where, it is not that only attraction gas, especially requirement are inhibiting the gas between the disorder of air-flow, air exhaust loop 32 to attract
Attract the technology of gas while the deviation of amount.
Therefore, present inventor is conceived to the size etc. for being formed in multiple gas vents 72 of air exhaust loop 32.That is, by with

In Fig. 6, Fig. 8, Tu11Zhong, following seven conditions are successively recorded from paper left as actual conditions.That is, note
It is loaded with the shape of (1) gas vent 72, the size of (2) each gas vent 72, the quantity of (3) gas vent 72, (4) multiple gas vents 72

As shown in fig. 6, the condition of the shape (above-mentioned (1)) of gas vent 72 be set as round and shape of slit this two
A condition.In addition, the condition of the configuration (above-mentioned (4)) of multiple gas vents 72 is to be set as first-class in the circumferential direction of air exhaust loop 32
Compartment of terrain arranges and is intensively configured at the two conditions of the two sides of left and right directions.In addition, (a), (d) in Fig. 7 are illustrated
The air exhaust loop 32 (the air exhaust loop 32a that circular gas vent 72a is equally spaced configured) of embodiment 2.(b), (e) in Fig. 7 are illustrated

Show the air exhaust loop 32 (the air exhaust loop 32c that the gas vent 72c of slit-shaped is equally spaced configured) of comparative example 4.
In Fig. 6, Fig. 8, Tu11Zhong, as analysis as a result, recording the traffic attraction of gas per unit time, an exhaust
The deviation (CV%) of gas traffic attraction between the deviation (CV%) of gas traffic attraction in ring 32, multiple air exhaust loops 32 and
Determine (OK or NG).The traffic attraction of gas per unit time carrys out table with the average value of the traffic attraction of each air exhaust loop 32
Show.That is, with the summation of the traffic attraction per unit time of the gas attracted from the inside of 12 air exhaust loops 32 divided by air exhaust loop 32
Quantity obtained from average value indicate.
As the deviation (hereinafter referred to as deviation in ring) of the gas traffic attraction in an air exhaust loop 32, record it is following that
The value of sample.Firstly, for each air exhaust loop 32, the mark of the data of the gas traffic attraction per unit time of multiple gas vents 72 is calculated
Quasi- deviation.Also, value obtained from the average value by standard deviation divided by the data of the traffic attraction is calculated separately (that is, calculating 12
The respective CV% of a air exhaust loop 32).Also, calculate the average value of this 12 CV%.By the average value of such calculated CV%
It is recorded as deviation in ring.
As the deviation (hereinafter referred to as interannular deviation) of the gas traffic attraction between 12 air exhaust loops 32, record following
Such value.Firstly, for each air exhaust loop 32, gas traffic attraction per unit time is calculated (that is, it is each to calculate 12 air exhaust loops 32
From traffic attraction data).In turn, the data by the standard deviation of the data of 12 traffic attractions divided by 12 traffic attractions are calculated
It is worth (that is, CV%) obtained from average value.Such calculated CV% is recorded as interannular deviation.
As described below like that, deviation becomes the disorder easness of the air-flow on the inside of air exhaust loop 32 (that is, the pendulum of silk thread in ring
Dynamic easness) index.For example, attracting compared with other gas vents 72 in some gas vent 72 of some air exhaust loop 32
In the case where amount more (that is, gas is unevenly discharged from a part of gas vent 72, being easy disorder in 32 interior air-flow of air exhaust loop),
The value of deviation becomes larger in ring.On the contrary, being suggested that in the lesser situation of deviation in ring: compared with the larger situation of the value, gas
It is more easily equably discharged from multiple gas vents 72, and inhibits the gas of 32 inside (that is, spinning near next long filament f) of air exhaust loop
The disorder of stream.
For example, when gas traffic attraction is more or less (that is, silk compared with other air exhaust loops 32 in a part of air exhaust loop 32
Swing mode of line etc. is easy to become different and silk thread quality is easy to produce deviation between multiple air exhaust loops 32) in the case where,
Interannular deviation becomes larger.On the contrary, being suggested that in the lesser situation of interannular deviation: compared with the larger situation of the value, in multiple rows
Gas is equably attracted between compression ring 32.
As the benchmark of judgement, the situation that deviation in ring and interannular deviation are 2% or less is set as OK, will be more than
2% the case where, is set as NG.Hereinafter, being illustrated to analysis result.
(the size interdependence of gas vent)
As shown in fig. 6, making the size of each gas vent 72 of air exhaust loop 32 in 7.1mm2~57mm2In the range of change,
And the comparison of deviation and the comparison of interannular deviation (Examples 1 to 8 and comparative example 1~4) in ring are carried out.As a result,
The size of each gas vent 72 is 7.1mm2 And 12.6mm2 In the case where (Examples 1 to 6), in ring deviation and
Interannular deviation becomes 2% or less (determining OK).It is 28.3mm in the size of each gas vent 722 In the case where, it is divided into and sentences
The case where determining OK (embodiment 7,8) and determine NG the case where (comparative example 1~3).It is 57mm in the size of each gas vent 722Feelings
Under condition (comparative example 4), it is determined as NG, especially, interannular deviation become greater to 3.1%.When each gas vent 72 is when becoming large-sized, energy
Enough observe deviation and interannular deviation bigger tendency in existing ring.
About the above results, present inventor considers as follows.First, it is believed that by the area for reducing each gas vent 72
Increase flow path resistance, is thus for example able to suppress by being configured at the gas vent close to the position for the interconnecting piece connecting with pipeline 33
72 gas vents 72 that are equal, holding runny position in gas and gas is intensively attracted.That is, by increasing each gas vent 72
Flow path resistance, be thus easy equably to attract gas by each gas vent 72, be able to suppress air-flow and focus on a part of exhaust
Hole 72, therefore, deviation becomes smaller in ring.It is regarded to inhibit to spin the air turbulence near next long filament f as a result,.
In addition, the present inventors considered that, by the area for reducing each gas vent 72, additionally it is possible to inhibit multiple air exhaust loops 32
Between gas traffic attraction deviation.I.e., it is believed that by inhibiting air-flow to concentrate on a part of gas vent 72, thus and in air flow collection
It is compared in the case where a part of gas vent 72, additionally it is possible to which the flow velocity for reducing 44 entirety of inner space for surrounding component 31 is uneven, also
It is able to suppress interannular deviation.
It is needed the area of each gas vent 72 at least according to the above in order to reduce deviation and interannular deviation in ring
It is set as substantially 30mm2Hereinafter, and increasing the resistance of each gas vent 72.More preferably, the area of each gas vent 72 is set as substantially
13mm2Hereinafter, and further increase the resistance of each gas vent 72, it is inclined thus, it is possible to further decrease deviation and interannular in ring
Difference.
Herein, the area of gas vent 72 is not the smaller the better, when the gas of monomer is in the inside of gas vent 72 or attached
When nearly solidification, gas vent 72 may also be blocked.Therefore, in order to inhibit gas vent 72 to block, preferably by the area of each gas vent 72
It is set as 7mm2More than.
(opening ratio interdependence)
Then, according to the analysis of the size interdependence of above-mentioned each gas vent 72 as a result, present inventor be conceived to
Lower aspect.That is, deviation and interannular deviation also depend on the quantity of gas vent 72 in ring even if the size of each gas vent 72 is identical
How much (that is, size of the total open area of each air exhaust loop 32) and change.In more detail, the present inventors considered that, in ring
Deviation and interannular deviation are also by total open area relative to the ratio of the size of the internal surface area of air exhaust loop 32, i.e. aperture efficiency
The influence of rate.
Therefore, present inventor pass through change as shown in Figure 8 each air exhaust loop 32 total open area condition with
And the condition of the internal surface area of air exhaust loop 32, to make to be open, ratio is changed in the range of 0.70%~3.88% (referring to Fig. 8's
Thick frame), and deviation in ring and interannular deviation are compared between Examples 1 to 8 and comparative example 1~3.Air exhaust loop
32 total open area is in 71mm2~396mm2In the range of changed.The internal surface area of air exhaust loop 32 becomes 10207mm2
(internal diameter) and 12076mm2(internal diameter) the two conditions.In addition, in fig. 8, only showing gas vent
72 shape is circular embodiment (Examples 1 to 8) and comparative example (comparative example 1~3).
Fig. 9 indicates to summarize the size interdependence of each gas vent 72 of deviation in ring and opening ratio interdependence
Chart.It is 28.3mm in the area of each gas vent 722Below and opening ratio is in about 3% situation below, in ring partially
Difference becomes 2% or less.When the ratio that is open becomes about 1.25% or less, deviation becomes 1.5% hereinafter, deviation is further in ring
It reduces.In addition, Figure 10 indicates to carry out the size interdependence and opening ratio interdependence of each gas vent 72 of interannular deviation
The chart summarized.It is 28.3mm in the area of each gas vent 722Below and opening ratio is in about 2.5% situation below,
Interannular deviation becomes 2% or less.When be open ratio become about 1.25% or less when, interannular deviation become 1% hereinafter, deviation into
One step is reduced.In addition, the area of gas vent 72 is set as 57mm2In the case where (comparative example 4), although ratio is small arrives for opening
1.80%, interannular deviation is also greatly to 3.1%.That is, being not only to reduce opening ratio, as described above, it is also necessary to reduce each
The area of gas vent 72.
According to the above, in the case where opening ratio is about 2.5% situation below (Examples 1 to 8), in ring deviation with
And interannular deviation be varied down to 2% hereinafter, be open ratio be more than 2.5% in the case where (comparative example 1~3), interannular deviation compared with
The earth is more than 2%.Also, in the case where opening ratio is about 1.25% situation below (Examples 1 to 4), obtain deviation in ring
It is lower than 1% result good in this way lower than 1.5%, interannular deviation.
About the above results, present inventor considers as follows.I.e., it is believed that when the ratio that is open is larger, every list of gas
The traffic attraction of position time becomes larger relative to the volume of the inner space of air exhaust loop 32, spins the air-flow near next long filament f and holds
Easy disorder.Additionally it is believed that being easy that gas is sharp discharged from the inside of air exhaust loop 32, in enclosure when the ratio that is open is larger
Air-flow is easy disorder in the inner space 44 of part 31, therefore interannular deviation becomes larger.On the other hand, it is believed that pass through the ratio suppression that will be open
It is made smaller, thus, it is possible to inhibit traffic attraction to become excessive relative to the volume of the inner space of air exhaust loop 32, the row of being able to suppress
The air turbulence of 32 inside of compression ring.Additionally it is believed that inhibiting smaller by the ratio that will be open, thus can also inhibit from air exhaust loop
The case where gas is sharp discharged in 32 insides, additionally it is possible to reduce interannular deviation.
In addition, in the identical embodiment of condition (embodiment 2,3) and ratio other than the internal surface area of air exhaust loop 32
Compared in example (comparative example 2,3), becoming in the case where the internal surface area of air exhaust loop 32 larger (that is, opening ratio smaller), in ring
Deviation and the biggish result of interannular deviation.It is considered that its cause is: in the biggish condition of the internal surface area of air exhaust loop 32
Under, compared with the lesser condition of internal surface area, the mutual interval of the air exhaust loop 32 to adjoin each other is relatively narrow, and the gas being discharged is each other
It collides and flows and be easy disorder.
The area by each gas vent 72 is needed to be set as in order to reduce deviation and interannular deviation in ring according to the above
Substantially 30mm2It is set as 2.5% or less below and by opening ratio.More preferably, opening ratio is set as 1.25% hereinafter, and more
Slowly attract gas, thus, it is possible to significantly reduce deviation and interannular deviation in ring.
(the configuration interdependence of gas vent)
In addition, as shown in figure 11, also having carried out fluid analysis to the configuration interdependence of multiple gas vents 72.That is, in addition to
In the identical embodiment of condition other than the configuration of gas vent 72 in each air exhaust loop 32, equally spaced match in multiple gas vents 72
The case where setting (referring to (d) in Fig. 7) and in the case where being intensively configured at two sides (referring to (e) in Fig. 7), in ring
Deviation and interannular deviation compare.Specifically, by embodiment 2 and embodiment 4, embodiment 7 and embodiment 8 respectively into
It has gone and has compared.As a result, gas vent 72 be configured to equally spaced situation under, deviation becomes larger several in ring, interannular deviation quilt
Inhibit small several.
About the above results, present inventor considers as follows.That is, due between multiple gas vents 72 of each air exhaust loop 32 etc.
It is arranged every ground, therefore gas is easy equably to be discharged in the circumferential direction of each air exhaust loop 32.Thereby, it is possible to make each air exhaust loop 32 weeks
The gas flow rate on side is close to uniform, therefore, compared in the periphery flow velocity of each air exhaust loop 32 significantly uneven situation, moreover it is possible to
Enough flow velocitys for inhibiting the inner space 44 for surrounding component 31 whole are uneven.It is regarded to that the traffic attraction of gas is inhibited to arrange as a result,
Deviation is generated between compression ring 32.Therefore, in order to reduce interannular deviation, preferably by multiple gas vents 72 in the circumferential direction of air exhaust loop 32
Equally spaced arrange.
In addition, being approached each other under conditions of multiple gas vents 72 are intensively configured at two sides with each gas vent 72
The case where ground configures is corresponding, and the gas traffic attraction attracted from each gas vent 72 easily becomes same degree, it is therefore contemplated that
Deviation is easy to become smaller in ring.On the other hand, when compared with the case where multiple gas vents 72 equally spaced configure, in each air exhaust loop
Gas is difficult to equably be discharged in 32 circumferential direction, it is therefore contemplated that interannular deviation become larger it is several.
(evaluation result of silk thread quality)
Then, present inventor is from embodiment and comparative example based on above-mentioned analysis as a result, choose several conditions, into
Gone silk thread quality real machine evaluation.It is explained its result using Figure 12.
As shown in figure 12, practical to manufacture silk thread for embodiment 2,5,6 and comparative example 2, and to the physical of the silk thread
Matter is evaluated.Firstly, the diameter of spinning head is set as common conditionThe internal diameter of air exhaust loop 32 is set
For(internal surface area 10207mm2), the thickness of silk thread is set as 0.41DPF.In addition, the shape of gas vent 72 is set
For circle, and the ratio that makes to be open change (the thick frame on the left of reference paper) in the range of 1.23%~3.88%, and produces
Four kinds of silk threads.The measurement result of U% (the thick frame on the right side of paper) is based primarily upon to carry out the evaluation of silk thread quality.U% is
Indicate the silk thread physical property of the deviation of silk thread thickness, value is smaller, is more difficult to generate specking, silk thread quality becomes good.Make
For the benchmark of judgement, the case where being set as OK, will be more than 0.6% the U% situation for being 0.6% or less, is set as NG.
As a result, in embodiment 2,5,6 U% be 0.6% or less and be determined as OK, U% is more than in comparative example 2
0.6% and be determined as NG.The ratio that is open is smaller and the value of deviation and interannular deviation is smaller in ring, then U% also becomes smaller,
Silk thread quality becomes more good.According to this as a result, it is possible to prove by reducing opening ratio for deviation in ring and interannular
Deviation inhibits smaller, and thus, it is possible to manufacture the better silk thread of quality, and it is consistent to confirmed that analysis result is evaluated with real machine.
As described above, by the way that the area of each gas vent 72 is set as 30mm2Increase the resistance of each gas vent 72 below,
Thus, it is possible to inhibit gas to be sharp discharged, and it is able to suppress the exhaust that gas holds runny position by being in gas
Hole 72 and intensively attracted.That is, being thus easy equably to inhale by each gas vent 72 by the resistance for increasing each gas vent 72
Bleed body is able to suppress air-flow in the inside of air exhaust loop 32 and concentrates on a part of gas vent 72.Also, ratio is set by that will be open
For 2.5% hereinafter, thus, it is possible to inhibit the traffic attraction per unit time of gas relative to the volume of the inner space of air exhaust loop
Become excessive, and is able to suppress the air turbulence of 32 inside of air exhaust loop.
In turn, by reducing the area of each gas vent 72, the gas that thus can also reduce between multiple air exhaust loops 32 is inhaled
The deviation for the amount of drawing.That is, thus concentrating on a part of gas vent 72 with air-flow by inhibiting air-flow to concentrate on a part of gas vent 72
The case where compare, can reduce surround component 31 inner space 44 it is whole flow velocity it is uneven, and multiple air exhaust loops can be reduced
The deviation of gas traffic attraction between 32.Also, by reducing opening ratio, and inhibit sharp to arrange from the inside of air exhaust loop 32
Gas out is able to suppress the gas in the inner space 44 for surrounding component 31 thus compared with the case where gas is sharp discharged
Fluid capacitance easily becomes the case where disorder, and can reduce the deviation of the gas traffic attraction between air exhaust loop 32.
As described above, by by the area of each gas vent 72 and opening ratio be set as specified value hereinafter, thus, it is possible to
Inhibit to spin air turbulence near next long filament f, and the inclined of gas traffic attraction between multiple air exhaust loops 32 can be reduced
Difference.
More preferably, by the way that the area of each gas vent 72 is set as 13mm2Hereinafter, and further suppressing 32 inside of air exhaust loop
Air-flow concentrate on a part of gas vent 72, thus, it is possible to significantly inhibit to spin the air turbulence near next long filament f, and
The deviation of the gas traffic attraction between multiple air exhaust loops 32 can significantly be reduced.
Further preferably, 1.25% is set as hereinafter, and further suppressing in air exhaust loop 32 by the ratio that will be open
The gas of side is sharp attracted, thus, it is possible to significantly inhibit to spin the air turbulence near next long filament f, and can be compared with
The earth reduces the deviation of the gas traffic attraction between multiple air exhaust loops 32.
In addition, by the way that the area of each gas vent 72 is set as 7mm2More than, thus, it is possible to inhibit gas vent 72 to block.
In addition, by the way that multiple gas vents 72 of each air exhaust loop 32 are equally spaced arranged in the circumferential, thus in each exhaust
Gas is easy equably to be discharged in the circumferential direction of ring 32.Thereby, it is possible to make the flow velocity of the gas on each 32 periphery of air exhaust loop close to
It is even, therefore, compared in the periphery flow velocity of each air exhaust loop 32 significantly situation of unevenness, additionally it is possible to inhibit to surround the interior of component 31
The whole flow velocity in portion space 44 is uneven.Therefore, the traffic attraction for being able to suppress gas generates deviation between air exhaust loop 32.
In addition, by making gas vent 72 become smooth round, thus it enables that gas is difficult to generate when being vented
Turbulent flow.Further, it is possible to block gas vent 72 by general pin, screw etc..That is, passing through the pin, the screw that make to block gas vent 72
Deng quantity increase and decrease, thus, it is possible to change total open area.Therefore, when changing total open area, no replacement is required air exhaust loop 32,
And total open area can be easily changed, therefore cost, labour can be saved.
Further, since being able to suppress the air turbulence spun near next long filament f, therefore, 0.5DPF or less is being spun
Thinner long filament f composition in, can particularly effectively inhibit the deviation of silk thread quality.
In addition, swimmingly being flowed from the air-flow that flow path reduces part 61 towards straight line portion 63 readily along bending part 62
It is dynamic.Accordingly, it is difficult to generate the removing of air-flow and be able to suppress the generation of vortex.
In addition, surrounding component 31 is divided into the 1st component 31a and the 2nd component 31b, the 2nd component 31b is relative to the 1st component
31a can be dismounted, and therefore, can easily be done the maintenance surrounded inside component 31.Therefore, it is able to suppress attraction decrease.
Especially, when the gas of monomer solidifies near bending part 62, straight line portion 63, the flow path of gas has can
It can blocking.The composition that component 31 is divided, the 2nd component 31b can be dismounted relative to the 1st component 31a is surrounded, for inhibiting flow path
It blocks highly effective.
Then, illustrate the variation that change is applied with to above embodiment.But for having and above embodiment

In the case of, the generation of vortex can also be inhibited by slowly attracting gas.
(2) in the above-described embodiment, it surrounds component 31 and is divided into the 1st component 31a and the 2nd component 31b, but not
It is defined in this.The not divided composition of component 31 is even surrounded, for example, it is also possible to add in maintenance to encirclement component 31
Heat is equal and monomer is made to gasify again, and acts suction pump 34 and attract gas, and thus flow path portion 60 cleans etc..Or
