Then, explain composite fibre silk and manufacture the structure of device 3.From device for spinning more than 2
Individual spinning head 7 spun multi-filament line Y walks downwards when arranging in left-right direction.As
Shown in Fig. 1, composite fibre silk manufactures device 3 to be possessed: a part of silk thread in traction multi-filament line Y
Y1 (the 1st of the present invention), generation, from the 1st tractive unit 16 of elongation silk, draw other silk thread
Y2 (the 2nd of the present invention) generates the 2nd tractive unit of the drawn yarn (FDY) as high-shrinkage filament
17, and as the interlacing device 26 by the also silk portion from elongation silk Y1 and high-shrinkage filament Y2 silk.
(the 1st tractive unit)
1st tractive unit 16 has 2 the 1st rollers 11 (11a, 11b), the 2nd roller 12 and heaters
18.2 the 1st rollers 11 draw from right side spinning head 7a spun silk thread Y1.1st tractive unit 16
When the chien shih silk thread Y1 of the 1st roller the 11 and the 2nd roller 12 is lax, utilize heater 18
Silk thread Y1 is carried out heat treatment without tension.
It addition, silk thread Y1 is wrapping with each of 2 the 1st rollers 11 with the angle that is wrapping with less than 360 degree
On individual.2nd roller 12 is arranged in the lower section of 2 the 1st rollers 11, and traction is sent here from 2 the 1st rollers 11
Multi-filament line Y1.Silk thread Y1 is also wrapping with on the 2nd roller 12 with the angle that is wrapping with less than 360 degree.
2 the 1st roller the 11 and the 2nd rollers 12 are rotated by not shown motor respectively and drive, each motor
Driving controlled by controlling device 5.Wherein, wire feed rate V2 of the 2nd roller 12 is than 2 the 1st rollers
Wire feed rate V1 of 11 is low.Therefore, the 1st roller 11 the silk thread Y1 sent here is at the 1st roller 11 and
It is relaxed between 2 rollers 12.
It addition, the 1st roller 11 both can be the heating roller possessing heater, it is also possible to be non-heating roller,
But from the viewpoint of following, preferably making the 1st roller 11 is heating roller.Silk thread Y1 is cold after spinning
But, and it is being suspended on the 1st roller 11 by the state last volume having paid oil preparation.Accordingly, it is believed that
Silk thread Y1 can not be carried out fully by heating by the short time of heater 18 later the most sometimes
Heat treatment.Therefore, in order to effectively carry out the heat treatment of heater 18, the 1st roller 11 is preferably made
For heating roller, with more than glass transition temperature and the preheating temperature silk thread Y1 of less than 100 DEG C.
Heater 18 is arranged between the 1st roller the 11 and the 2nd roller 12, the silk thread of heating relaxed state
Y1.The structure of heater 18 has no particular limits, it is possible to be suitably used such as infrared heating
Devices etc. heat the heater of silk thread non-contactly.
Wherein, by suitably setting the wire feed speed of wire feed rate V1 of the 1st roller 11, the 2nd roller 12
Degree V2 and heating-up temperature T of heater 18, it is possible to pay from extensibility to silk thread Y1.Separately
Outward, so-called " from extensibility " is to being wound in the operation later of the silk thread after device 4 winds
Gone heat treatment time the character that automatically extends.Further, carry out for paying from extensibility to silk thread Y1
The 1st roller 11b, the 2nd roller 12 and the heater 18 of heat treatment without tension be equivalent to the " pine of the present invention
Relaxation heat treatment portion ".
Pay the mechanism from extensibility to silk thread and have various theory, but wherein following theory is more powerful.
First, when spun silk thread is made a reservation for above speed drawing with certain, this silk thread generates and comprises crystalline phase
And the fibre structure of the amorphous phase being present between crystalline phase.Generally, the amorphous phase between crystalline phase is along fine
The state of dimension direction of principal axis orientation, when implementing heat treatment in subsequent handling, amorphous phase is along differently-oriented directivity
(fiber axis direction) shrinks, thus silk thread entirety is significantly shunk.
On the other hand, by suitably set the condition of wire feed rate, the temperature conditions of heater 18 and
Relaxation condition, it is possible to realize there is the amorphous phase close to No yield point state between appropriately sized crystalline phase
State.When the silk thread of this state is implemented heat treatment in subsequent handling, owing to amorphous phase is without taking
To, therefore different from the common silk thread previously illustrated, do not produce the contraction of amorphous phase, on the contrary,
Crystalline phase is grown up and is become big, therefore silk thread overall elongated.
As from above explanation it will be appreciated that as, in order to become the silk thread having from extensibility, with
Lower 2 extremely important: (1) amorphous phase is close to the state of No yield point, amorphous in follow-up heat treatment
Not shrinking mutually, (2) crystalline phase is the most undue grows up, and has the leeway grown up in follow-up heat treatment.For
Realize this 2 point, it is necessary to suitably set the condition of wire feed rate, temperature.
If the wire feed rate of the 1st roller 11 is too low, owing to not generating crystalline phase, become single amorphous phase,
Even if therefore carrying out heat treatment, the most only amorphous phase is shunk, and does not cause crystalline growth.On the other hand,
If the wire feed rate of the 1st roller 11 is too high, otherwise then the growth of crystalline phase is too fast, in subsequent handling
In heat treatment, crystalline phase is no longer grown up, and silk thread Y1 extends hardly.Therefore, the wire feed of the 1st roller 11
Speed V1=2500～4000m/min are preferably.
Further, in order to by making the amorphous phase No yield point of silk thread Y1 relax internal strain, add hot charging
The temperature putting 18 at least needs higher than the glass transition temperature of fiber.Further, if heating-up temperature is low,
Then it is not sufficiently solidified due to fibre structure, easily by external environment condition time when transport, keeping
Impact.On the other hand, if the temperature of heater 18 is too high, then the crystalline phase mistake within silk thread Y1
In growth, the problem that when there is the heat treatment of subsequent handling, the percentage elongation of silk thread Y1 diminishes.Thus while
Heating-up temperature T of heater 18 also will according to the heat treatment temperature of subsequent handling, but use 100～
150 DEG C preferably.
And, fully relax the internal strain of amorphous phase for carrying out heating by heater 18,
It is effective for carrying out heating when making silk thread Y1 lax.Thus, civilian with the patent of previously citing
The constant-length heat treatment offering 1 (Japanese Unexamined Patent Publication 2000-54239 publication) is compared, it is possible to produce from elongation
The silk thread that property is excellent.For being relaxed to any degree preferably, when defining relaxation rate (over feed rate(OFR)) rf
During=((V1-V2)/V2) × 100, making this relaxation rate rf is 1%～10% preferably.
When silk thread Y1 being carried out heat treatment without tension with above-mentioned condition, pay from extensibility to silk thread Y1.
The boiling water percentage elongation of silk thread Y1 for such as 5%～10% (when utilizing percent thermal shrinkage to describe, for-5%～
-10%).
(the 2nd tractive unit)
2nd tractive unit 17 possesses 20,2 the 3rd rollers 13 of couveuse and 2 the 4th rollers 14.Insulation
Case 20 utilizes thermal insulation material to be formed, and is arranged in the lower section of left side spinning head 7b.At couveuse 20
Upper wall portions is formed with silk thread introducing port 20a, is formed with silk thread export mouth in the right wall portion of couveuse 20
20b.Couveuse 20 is imported from silk thread introducing port 20a from left side spinning head 7b spun silk thread Y2
In.
Contain in couveuse 20 2 the 3rd rollers 13 (13a, 13b) and 2 the 4th rollers 14 (14a,
14b).2 the 3rd rollers 13 are arranged in the upper space in couveuse 20, and 2 the 4th rollers 14 configure
Lower space in couveuse 20.These 4 rollers 13,14 are rotated respectively by not shown motor
Driving, the driving of each motor is by controlling device control.
First the silk thread Y2 imported in couveuse 20 from silk thread introducing port 20a is wrapping with to 2 the 3rd
On roller 13, then it is wrapping with on 2 the 4th rollers 14.It addition, silk thread Y2 is with less than 360 degree
It is wrapping with angle to be wrapping with in each of 4 rollers 13 (14).
The wire feed rate of 2 the 3rd rollers 13 and the setting of the wire feed rate of 2 the 4th rollers 14 are described.
Firstly, for wire feed rate V3 of 2 the 3rd rollers 13, make the wire feed of the 3rd roller 13b in downstream
Speed V3b wire feed rate V3a than the 3rd roller 13a of upstream side is the fastest.The speed of V3a Yu V3b
Difference is preferably at about 50m/min.The most also will describe, 2 the 3rd rollers 13 are for being used for preheating silk thread
The roller of Y2.Owing to during preheating, the internal stress of silk thread Y2 is alleviated, therefore to prevent silk thread Y2
Lax, improve the wire feed rate of roller 13b in downstream preferably.On the other hand, for 2 the 4th rollers
Wire feed rate V4 of 14, makes wire feed rate V4a and the 4th of the downstream of the 4th roller 14a of upstream side
Wire feed rate V4b of roller 14b is roughly the same.
Further, wire feed rate V3 of the 3rd roller 13 (13a, 13b) and the 4th roller 14 (14a, 14b)
The relation of wire feed rate V4 be V4 ＞ V3.Thus, between the 3rd roller 13b and the 4th roller 14a,
Silk thread Y2 is stretched.
Further, 4 rollers 13,14 possess heater 30 in respective inside.Beating of each heater 30
Opening/closing (ON/OFF) controls and temperature controls to be carried out by above-mentioned control device 5.To each roller 13 (14)
By making heater 30 become ON, it is possible to each roller is used as the heating roller of heating silk thread Y2.
Further, if making heater 30 become OFF, it is possible to using each roller as the non-power of not heater strip line Y2
Hot-rolling uses.It addition, in order to make the judgement of the ON/OFF of heater 30 become easy, at Fig. 1
Middle black fills the heater 30 of ON state, and the heater 30 of OFF state does not fills.
2 the 3rd rollers 13 are the roller that silk thread Y2 is preheating to the temperature that can stretch.Wherein, control
Device 5 makes heater 30 be normal ON for each in 2 the 3rd rollers 13, by 2 the 3rd
Roller 13 uses as heating roller.Temperature T3b of the roller 13b of 2 the 3rd roller 13 middle and lower reaches sides sets
It is set to the temperature of more than the glass transition temperature of fiber (such as, in polyethylene terephthalate
80～90 DEG C it are set as) in the case of fiber.On the other hand, for the roller 13a of upstream side, be wrapping with from
Couveuse 20 outer that import, paid the silk thread Y2 of oil preparation state.Therefore, in order to make silk thread Y2
The 3rd roller 13b in downstream is heated to more than glass transition temperature effectively, it is necessary to utilize
3rd roller 13a of upstream side pays substantial amounts of heat to silk thread Y2.Therefore, the temperature of the roller 13a of upstream side
Temperature T3b that degree T3a is preferably set to than the roller 13b in downstream is slightly higher.It addition, T3a with
The temperature difference of T3b is such as about 5 DEG C.
On the other hand, for 2 the 4th rollers 14, according to whether after the stretch silk thread Y2 is carried out heat
Process (thermal finalization) and switch the ON/OFF of heater 30.In the case of not carrying out thermal finalization,
Controlling device 5 makes heater 30 become each in 2 the 4th rollers 14 as shown in FIG. 1
2 the 4th rollers 14 are used by OFF as non-power hot-rolling.On the other hand, after the stretch to silk thread
In the case of Y2 carries out thermal finalization, control device 5 and each in 2 the 4th rollers 14 is made heating
Device 30 becomes ON (Fig. 2 with reference to being discussed below).
The silk thread Y2 in couveuse 20 is imported first by 2 the 3rd rollers 13 from silk thread introducing port 20a
Conveying, and it is preheating to the temperature (glass transition temperature) that can stretch.Then, silk thread Y2 is by
Wire feed rate difference stretching between 3 roller 13b and the 4th roller 14a.Further, as it is shown in figure 1,2
In the case of individual 4th roller 14 is non-power hot-rolling, the silk thread Y2 after stretching is not carried out thermal finalization (non-
Thermal finalization FDY), silk thread Y2 becomes the silk thread that percent thermal shrinkage is high.The boiling water shrinkage of silk thread Y2 is
Such as 10%～20%.
Silk thread Y2 after stretching is exported to couveuse 20 by 2 the 4th rollers 14 from silk thread export mouth 20b
Outward.And, silk thread Y2 is wrapping with on the 2nd roller 12.It addition, silk thread Y2 is also with less than 360 degree
The angle that is wrapping be wrapping with on the 2nd roller 12.Now, silk thread Y1 and silk thread Y2 from side, front
(front side) Kan Shisi road is consistent.
In the downstream leaning on silk thread direction of travel than the 2nd roller 12, it is configured with the interlacing device 26 (present invention
And silk portion) and thread delivering roller 15.The silk thread Y1 and the silk thread Y2 that are sent here by the 2nd roller 12 fill at cross winding
Put in 26 by also silk, become composite fibre silk Ym.Interlacing device 26 is not defined as ad hoc structure
Device, it is possible to use such as from the direction jet airstream orthogonal with the direction of travel of silk thread Y, make many
What root ultimate fibre was wound around mutually has the structure of interlaced jet.Such as, silk thread Y1's and silk thread Y2
In the case of radical is respectively 4, interlacing device 26 possesses 4 interlaced jet.In each interlaced jet
Insert 1 silk thread Y1 and 1 silk thread Y2, in each nozzle, constitute 2 silk threads Y1, Y2
Ultimate fibre is cross winding under the effect of air stream.Thus, interlacing device 26 4 composite fibre silks are generated
Ym.The many composite fibre silk Ym generated by interlacing device 26 are carried to coiler device 4 by roller 15,
Coiler device 4 is wound up into respectively on multiple bobbin 23.
In this embodiment of mistake described above, utilize the 1st from device for spinning 2 spun silk thread Y1
Tractive unit 16 draws.In the 1st tractive unit 16, by the 1st roller the 11 and the 2nd roller 12 it
Between silk thread Y1 is carried out heat treatment without tension with predetermined condition, pay from extensibility to silk thread Y1.That is,
Due to from spinning to from the generation of elongation silk streamlined carry out, manufacture from extending silk therefore, it is possible to reduce
The labour spent and time, cost.
Further, owing to heating silk thread Y1 with lax state between the 1st roller the 11 and the 2nd roller 12,
Therefore the alleviation of the internal strain of silk thread Y1 is promoted.Therefore, the amorphous phase of silk thread Y1 provides easy access to nothing
The state of orientation, it is possible to be derived from the silk thread Y1 that extensibility is high.
In addition, in the spinning traction apparatus 1 of this embodiment, by interlacing device 26 also
Silk is as from the silk thread Y1 and other silk thread Y2 of elongation silk, it is possible to produce composite fibre silk Ym.
It is that silk thread Y2 is to be drawn between the 3rd roller the 13 and the 4th roller 14 of the 2nd tractive unit 17 in more detail
The drawn yarn (FDY) stretched.Further, owing to the 4th roller 14 is non-power hot-rolling, after silk thread Y2 is for stretching
Not carrying out the silk thread (non-thermal finalization FDY) of thermal finalization, therefore the percent thermal shrinkage of silk thread Y2 is high.Pass through
And silk is as the silk thread Y1 from elongation silk and the silk thread Y2 as high-shrinkage filament, it is possible to produce 2 kinds of silks
The composite fibre silk Ym that the difference of the percent thermal shrinkage of line is the biggest.
Further, as it is shown in figure 1, the silk thread Y1 drawn by the 1st tractive unit 16 is with less than 360 degree
It is wrapping with angle to be wrapping with in each of 2 the 1st roller the 11 and the 2nd rollers 12.Further, led by the 2nd
The silk thread Y2 drawing portion 17 traction is also wrapping with 2 the 3rd rollers respectively with the angle that is wrapping with less than 360 degree
In each of 13 and 2 the 4th rollers 14.Therefore, at silk thread Y after device for spinning 2 spins,
When utilizing the 1st tractive unit the 16 and the 2nd tractive unit 17 traction, silk road will not be along the direction of principal axis of each roller
Skew.Therefore, it is being close to before interlacing device 26, it is possible to make silk road and the silk thread of silk thread Y1
The silk road of Y2 is consistent.
Spinning traction apparatus 1 is used for from extending silk and non-thermal fixed it addition, above explanation describes
The example of the mixed fibre of type FDY, but the spinning traction apparatus 1 of this embodiment also is able to for manufacturing it
The silk thread of his kind.Hereinafter give some instances.
(1) from the manufacture of elongation silk and the composite fibre silk of thermal finalization FDY as in figure 2 it is shown, right
Each of 2 the 4th rollers 14 of the 2nd tractive unit 17 also makes heater 30 become ON.
As its purpose, the difference of the percent thermal shrinkage reducing two kinds of silk threads can be enumerated, make as final system
The smooth surface of the fabric of product.In this case, heating-up temperature T4 (the roller surface of 2 the 4th rollers 14
Temperature) higher, for such as 100～150 DEG C than heating-up temperature T3 of 2 the 3rd rollers 13.Thus, exist
The silk thread Y2 being stretched between 3rd roller the 13 and the 4th roller 14 is by thermal finalization, as from elongation silk
Silk thread Y1 and silk thread Y2 quilt silk in interlacing device 26 as thermal finalization FDY.Ordinary circumstance
Under, owing to thermal finalization FDY is in a ratio of, with described non-thermal finalization FDY, the silk thread that percent thermal shrinkage is low, because of
The difference of the percent thermal shrinkage between this silk thread Y1 and silk thread Y2 diminishes.
Further, different from above-mentioned, in order to make the percent thermal shrinkage stabilisation of silk thread Y2, it may be considered that to 2
Each of individual 4th roller 14 makes heater 30 become ON.In this case, the temperature of 2 the 4th rollers
Degree T4 there is no need to become the highest temperature, for such as 50～100 DEG C.
(2) only from the manufacture of elongation silk as shown in Figure 3, it is also possible to by utilizing the 1st tractive unit 16
All multi-filament line Y that traction spins from device for spinning 2, only manufacture from extending silk.
(3) manufacture of the composite fibre silk of POY and FDY is as shown in Figure 4, at the 1st tractive unit
In 16, if making the 1st roller 11 and wire feed rate V1 of the 2nd roller 12, V2 identical, and make to add
If thermal 18 becomes OFF, then do not carry out lax and heat treatment on silk thread Y1.Thus, do not give birth to
Become from extending silk, it is possible to generate POY (partially oriented yarn).In this case, (high as POY
Contractile filaments) silk thread Y1 and as the silk thread Y2 of thermal finalization FDY (lower shrinkage silk) at interlacing device
In 26 and silk.
(4) manufacture of only FDY is as shown in Figure 5, it is also possible to by utilizing the 2nd tractive unit 17 to lead
Draw all multi-filament line Y spun from device for spinning 2, only manufacture FDY.Although it addition, Fig. 5
In illustrate the situation only manufacturing thermal finalization FDY, but 2 the 4th rollers 14 can also be made in Figure 5
Heater 30 become OFF, thus only manufacture non-thermal finalization FDY.
(5) manufacture of only POY is in the 1st tractive unit 16, makes the 1st roller the 11 and the 2nd roller 12
Wire feed rate V1, V2 identical, and make heater 18 become OFF.On this basis, also
Can as shown in FIG. 6, by utilize the 1st tractive unit 16 to draw to spin from device for spinning 2
All of multi-filament line Y, only manufactures POY.
Then, illustrate described embodiment is applied with the change form of all changes.But, for
There is the part of the structure identical with described embodiment, add identical reference, suitably save
Slightly its explanation.
1) can be as the chien shih from the silk thread Y1 and the silk thread Y2 as high-shrinkage filament of elongation silk
The thickness (filamentary thickness, filamentary quantity) of silk thread is different.To the composite fibre being wound
When silk Ym carries out heat treatment in subsequent handling, the silk thread Y1 of elongation is positioned at outside becomes sheath silk, receives
The silk thread Y2 of contracting is positioned at inner side becomes core filaments.Wherein, if the silk thread Y1 such as becoming sheath silk is
Filament, becomes if the silk thread Y2 of core filaments is crin, then elastic force, elastic strong, and becomes soft
The silk of sense of touch, preferable in terms of feel.It addition, in order to change silk thread Y1 and the thickness of silk thread Y2,
As long as making the structure spinning the spinning head 7 of each silk thread (spin the size in filamentary hole or the number in hole
Amount) or the output of polymer different the most permissible.
2), in described embodiment, each in 2 the 3rd rollers 13 and 2 the 4th rollers 14 sets
Putting heater 30, these 4 rollers 13 (14) are housed in couveuse 20.In contrast, the 2nd
Tractive unit 17 is specifically generated non-thermal finalization FDY, and the silk thread Y2 after stretching does not carries out the feelings of thermal finalization
Under condition, owing to always the 4th roller 14 being used as non-power hot-rolling, therefore not at the 4th roller 14
Necessity of heater 30 is set.In this case, 2 the 4th rollers 14 can also be arranged in couveuse
Outside 20.
3) can also separate near the 1st roller 41 ground configuration as the spinning traction apparatus 61 of Fig. 7
Roller 43, silk thread Y1 is wrapping with more than once between the 1st roller 41 and separate roller 43.If silk thread Y1
1st roller 41 is wrapping with more than once, even if then owing to reducing the diameter of the 1st roller 41, silk thread Y1
Contact length the most elongated, curable grip becomes big, and therefore silk thread Y1 is not easy to skid.Further, since carry
High curable grip is main purpose, and therefore the number of times that is wrapping with of silk thread Y1 need not be too many, is sufficient for several times.
4) although in described embodiment, 2 the 3rd rollers 13 for the 2nd tractive unit 17 make heating
Device 30 becomes ON, uses as heating roller but it also may using 2 the 3rd rollers 13 as non-heated
Roller uses.Such as, in the case of fibrous material is nylon, due to glass transition temperature low (40～
50 DEG C), the most in most cases need not the preheating before stretching.In this case, as long as making
3 rollers 13 are that non-power hot-rolling is the most permissible.
5) structure of the roller of the 2nd tractive unit 17 is not limited to the structure of described embodiment, permissible
The suitably change quantity of roller, configuration.
6) the 2nd roller in the 1st tractive unit 16 can also be made as the spinning traction apparatus 71 of Fig. 8
12 is the heating roller with heater 50, and omits heater 18.In this case, the 1st
Silk thread Y1 lax between roller the 11 and the 2nd roller 12 is added by the surface of the 2nd roller 12 as heating roller
Heat, carries out heat treatment.With heater 18 heater strip of the cordless utilizing Fig. 1 in this structure
The situation of line Y1 is compared, owing to the surface of silk thread Y1 and the 2nd roller 12 contacts, is directly heated,
Therefore, it is possible to more effectively heat silk thread Y1.It addition, in the structure of Fig. 8, due to by the 2nd tractive unit
The silk thread Y2 of 17 tractions also be heated by the 2nd roller 12, and therefore the structure of Fig. 8 is particularly suited for silk thread
Y2 is by the situation of the 4th roller 14 thermal finalization.
7) although in described embodiment, primarily illustrating and produce polyethylene terephthalate silk thread
In the case of, all conditions (the 1st roller of the 1st tractive unit 16 when extensibility is paid to silk thread Y1
Wire feed rate, the heating-up temperature of heater 18 and the relaxation rate of 11), but these conditions are because of production
The kind of silk thread is different and certainly different.That is, if the kind of silk thread changes, then it is used for paying from stretching
The setting of all conditions of long property also becomes different.
