The present invention relates to a manufacturing method of biaxial blended yarn, such as polyester fiber, and an auxiliary device and a spinning head used therein.

The use of a biaxially blended yarn in which two or more types of multifilament yarns having different shrinkage rates due to boiling water are used can improve the quality of the knitted fabric.

Such a biaxially blended yarn is usually produced by spinning the blending yarn separately and stretching under different heat treatment conditions to be spun together.

However, in order to thermally heat each of them separately, it is necessary to wind and transport the yarn through various processes and to increase manufacturing costs.

Therefore, there have been proposed a method of shortening each step such as a spinning step, a heat treatment step, a stretching step, a brazing step, and the like to obtain a biaxially blended fiber in a simple manner, or a variety of biaxially blended fiber obtained in the same manner.

For example, Japanese Unexamined Patent Application Publication No. 50-32574 discloses that when the apparatus of FIG. 18 is used, diaxial mixed fiber is continuously obtained from the spinneret of the same weight.

That is, this method divides the filament discharged from the spinning nozzle 83 into two groups and passes the superstretch through the rollers 84, 85, 86 and 87 with respect to one bundle 81 of the filament. After the gun is heat treated in the hot plate 90 to obtain a yarn A having a predetermined boiling water shrinkage, the rollers 84 ', 85', 87 'are sequentially passed through the other side 81 of the filament bundle. After stretching, heat treatment is performed on the hot plate 90 'to obtain a chamber B having a smaller residual shrinkage than the above-mentioned chamber A.

Then, the yarns (A) and (B) are spun together through the guide portion 92 and wound around the package 94.

The blended yarn obtained in this way has at least 2% of residual shrinkage when there is no load on both yarns (A) and (B), thereby providing better quality.

However, the above-described apparatus uses a plurality of rollers to make a difference in shrinkage rate, and it is difficult to adjust the rotational speed and the heating temperature of each roller. In addition, since the filaments discharged from the same spinning nozzle 3 are divided into two groups, the raw materials of the filaments cannot be the same, and even if the rotational speed of each roller is adjusted, there is a limit to the difference in shrinkage of the yarns obtained. In addition, there is a problem in that a combination with a lot of change is not obtained.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a two-shaft mixed fiber manufacturing method in which a combination of two-weave yarns with many changes can be obtained by simple setting of conditions by using two mutually adjacent radial drawing apparatuses.

In order to achieve the above object, the present invention uses a radial drawing device of two weights adjacent to each other to discharge the molten polymer from the spinning nozzle of one radial drawing device to guide the drawing part while making a seal, The yarn is heat treated by stretching the yarn between two pairs of godet rollers G1 and G2 to obtain a yarn A having a predetermined boiling water shrinkage, and from the spinning nozzle of the other The molten polymer is discharged and made into a yarn while inducing it to a drawing section. The boiling water is different from the above-mentioned yarn (A) by drawing and heat-treating the yarn between two pairs of Godet rollers (G3) (G4). I-shrink blended yarn obtained by obtaining a yarn (B) having a shrinkage ratio and rolling the aforementioned yarn (A) (B) side by side over the above-described Godet roller (G4) and then mixed by fluid entanglement to obtain a biaxial shrink blended yarn. Making the manufacturing method the first point And an auxiliary device used to roll the above-mentioned thread (A) (B) side-by-side over the Godet roller G4, and the thread guide installed to cross the guide path of the thread A of the Godet roller G4 side. The control guide and the thread guide described above are provided with a moving means for moving the regulation guide from side to side with respect to the guide path of the thread A. When the regulation guide is threaded with the thread guide described above, the guide of the thread A is provided. Is positioned at the position overlapping the guide path of the thread B on the Godet roller (G4), and after the thread is hooked, the guide path of the thread (A) moves away from the guide path of the thread (B), and both run side by side. A patent for providing two types of molten polymers to the spinning nozzles of two weight-stretching apparatuses adjacent to each other via a spinning head in which a predetermined polymer flow path is formed. The manufacturing method of Isu shrink blended fiber of Claim 1 of Claim The inside of the above-mentioned spinning head is composed of any one of the following two types of distribution blocks (C) and (D), which can be exchanged, to produce this polymer blend fiber using the distribution block (C) described above, and the distribution block described above. Spinning for simultaneously supplying two kinds of molten polymers to two adjacent stretching apparatuses of two weights, with the manufacturing method of a biaxially blended yarn made to produce conjugated yarns using (D). The head has a polymer inlet connected to each molten polymer source on the outer surface thereof and a polymer inlet connected to each of the spinnerets of each of the spinnerets, and a polymer flow path from the above polymer inlet to the polymer inlet is formed on the outer surface. A fourth aspect of the present invention is a spinning head constituted by any one of the two types of distribution blocks (C) (D) described below, which are detachably attached to the main body.

(C) The same type of molten polymer having polymer flow paths introduced into the spinning nozzle of the same spinning apparatus.

(D) The above-mentioned two kinds of polymers are provided with the polymer flow path which distributes and introduces into the spinning nozzle of each spinning apparatus.

That is, the present invention is not to supply the raw material polymer from the same weight, but to supply the raw material polymer from two different weights so as to obtain a bishrinkage mixed yarn, so that the type and discharge conditions of the supplied polymer can be set separately. It is possible to produce abundant blended yarns with different rates of boiling water shrinkage.

In addition, there is no need to increase the number of rollers in the stretched portion in particular for the stretching and heat treatment of the yarn, and the adjustment of the rollers is simple.

As a spinning head for supplying the raw material polymer to the two weights described above, a single equipment can be manufactured and conjugated to different polymer blended yarns by using a special spinning head having two kinds of exchangeable distribution blocks having different polymer flow paths formed therein. It can divide and use for manufacture of the company.

This invention is demonstrated in detail based on the following Example.

EXAMPLE

1 shows one example of an apparatus used in the practice of the present invention.

This apparatus is provided with two spinning weights used in a conventional spindler system in a pair, and includes a spinning section 21, a stretching section 22, and a plywood winding section 23.

The two adjacent weights of the radiating section 21 are provided with spinning nozzles 25 and 25a, cooling devices 26 and 26a and oil ring rollers 27 and 27a, respectively.

In addition, four stretch rollers 31, 32, 33, 34 are provided in the drawing section 22 as shown in the drawing.

In the drawing, the first Godet roller 31 on the left side recovers the yarn A discharged from the above-described spinning nozzle 25, and the third Godet roller 33 is discharged from the above-mentioned spinning nozzle 25a. The used yarn B is recovered.

In addition, separator rollers 31a and 33a face each other in the Godet rollers 31 and 33, and the yarns A and B are Godde rollers 31 and 33 as shown in the drawing. ) And is wound several times on the outer circumference of the oval made of separator rolls (31a) (33a).

Then, the yarn A wound around the first goet roller 31 is elongated while being wound around the second goet roller 32 and passes over the fourth goet roller 34 to pass through the plywood winding portion 23. Leads to

Moreover, the yarn B wound up by the 3rd Godde roller 33 is extended and wound up by the 4th Godde roller 34, and reaches the plywood winding part 23. As shown in FIG.

In addition, separator rollers 32a and 34a are provided in the vicinity of each of the rollers 32 and 34 so as to face each other, and the seals (A) and (B) are the rollers 32 and 34 and the separator. It is to be wound several times on the outer circumference of the oval made of the rolls 32a and 34a.

In the plywood winding section 23, "40" enters into the nozzle 40 in a state where the yarns A and B, which have passed through the fourth Godet roller 34, are interlaced with the interlaced nozzles one by one. It becomes the horn-some yarn that bumped and formed the entanglement.

This blend fiber is wound into the package 42 on the substrate 43 by rotation of a friction roller 41.

The present invention uses the above apparatus, for example, to produce biaxial blended yarn as follows.

That is, first, polyethylene terephthalate having an intrinsic viscosity of 0.64 is discharged at a discharge amount of 19 g / minute from the spinning nozzle 25a (hole number 24) at 290 ° C.

The oil ring roller 27a is applied to the oil ring roller 27a after cooling and hardening by blowing air from the cooling device 26a.

Subsequently, the yarn obtained after cooling and hardening to the third gode roller 33 heated to 78 ° C. and rotating at 1210 ml / min was pre-wound several times through the separator roll 33a, and then heated to 90 ° C. to 3500 m / min. It winds through the separator 34a several times in the rotating 4th God roller 34, and it extends between both Godde rollers 33 and 34, and performs thermosetting.

In this way, a yarn B having a high boiling water shrinkage is obtained.

On the other hand, polyethylene terephthalate having an intrinsic viscosity of 0.64 is discharged at a discharge amount of 19 g / min from the spinning nozzle 25 (hole number 24) at 290 ° C.

Then, the oil is supplied to the oil ring roller 27 after hardening by cooling by blowing from the cooling device 26.

Subsequently, the yarn obtained by cooling and hardening to the 1st high-dew roller 31 which rotates at 80 degreeC and rotates at 1250 m / min is pre-wound several times through the separator roll 31a, and it preheats, and then it heats to 130 degreeC and it is 3510 m / min. It winds through the separator roller 32a several times to the rotating 2nd Godde roller 32, and it extends between both Godde rollers 31 and 32, and performs thermosetting.

In this way, a yarn A having a low boiling water shrinkage is obtained.

Then, the thread A is guided onto the fourth Godet roller 34, and the yarns A and B are simultaneously pulled out of the fourth Godet roller 34 and passed through the interlace nozzle 40. Then, both chambers (A) and (B) are fluidly entangled and mixed together, and wound around the branch pipe 43 at a speed of 3480 m / min. In this way, the target biaxial blended yarn is obtained.

The physical properties of the yarns (A) and (B) described above are as follows, and since the difference in shrinkage due to the boiling water of both is extremely large, the use of both blended yarns results in a beautiful knitted fabric that has not been obtained conventionally.

The rotational speeds, heating conditions, and the like of each gothic roller are not limited to the above-described embodiments, but are appropriately set according to the characteristics of the raw material resin, the boiling water shrinkage ratio of the target yarn, and the like.

In addition, the present invention is not limited to the above-described embodiment, and is easily changed by boiling water by changing the type of raw polymer discharged from the spinneret spinning nozzles 25 and 25a, the discharge conditions, and the combination of the cross sections of the yarns. Not only the shrinkage rate is varied but also the rich blended yarn is obtained.

As a typical combination of such mixed fiber, the following is mentioned, for example.

(1) High shrink polyester yarns copolymerized with isophthalic acid and split composite yarns (combined with two kinds of polymers with poor interadhesion or composite yarns with easy-to-dissolve polymers and difficult-to-dissolve polymers. Fiber is divided into a very thin thread), and a combination of a simple polyester yarn or a combination that gives them a difference in heat shrinkage.

② Combination of yarn with relatively high Young's modulus such as polybutylene terephthalate and nylon and yarn with relatively low Young's modulus such as polyester.

③ Combination using high viscosity polymer and low viscosity polymer as raw material polymer.

④ Combination of yarns with different cross-sectional shapes of yarns obtained by using different nozzles with different cross-sectional shapes.

⑤ Combination of yarns with different total denier or dansadenir.

In addition, the above-mentioned blended yarn is wound at high speed with a high speed winder and wound around the branch pipe 43 to be cheeseed. However, the branch pipe 43 used in this case is larger in diameter and thicker than the conventional branch pipe in terms of strength.

In addition, in the conventional method of winding the blended yarn with a smoke machine, the general dimensions of the branch pipe used for the winding are 75mm outside, 69mm inside, 3mm thick, and 290mm long, but are used for winding the blended yarn of the present invention. Typical dimensions of the branch pipe 43 are 103mm in outer dimension, 89mm in inner dimension, 7mm in thickness, and 102.5mm in length (or 205mm).

In addition, since the boiling water shrinkage ratios of the two types of mixed yarns are greatly different, the mixed fiber obtained by the present invention has different polymer SPD method of the same weight (dividing the inside of the same hopper into two different polymers in the same spinning nozzle It is clearly distinguished from the blended yarn which has a small difference in the boiling water shrinkage ratio obtained by the method).

In the manufacturing method of the above-described embodiment, it is appropriate to thread in the following steps under high speed conditions of 4000 m / min or more in the threading step.

That is, first, the above-described apparatus is started to start spinning, and the yarn B dropped from the spinning nozzle 25a of the spinning unit 21 is sucked and held by an air circulator (generally used when threading), and the third It is fastened to the Gode roller 33 and the fourth Gode roller 34 in turn.

And extends downward from the fourth Godet roller 34 and transfers the yarn to the water circulator 51 to the air circulator 50 as shown in FIG.

This state is shown in FIG.

Next, the thread A, which has been dropped from the spinning nozzle 25 of the spinning unit 21, is similarly sucked and held by the air circuit 50 ', and is then applied to the first Godet roller 31, and then separated from the separator roller 31a. It hangs on the detro roller 32 and winds only a predetermined number of times between them.

Subsequently, the thread A is hooked on the second Godde roller 32, and as described above, only a predetermined number of times are wound between the separator roll 32a and the Gode roller 32.

Then, as shown in FIG. 4, the thread A is extended in the horizontal direction, and the thread A is stretched downward to the fourth Godet roller 34, and the thread A is stretched downward.

This state is shown in FIG.

In this way, the thread walking up to the plunge winding unit 23 is performed in a state in which two kinds of yarns (A) and (B) are suctioned and held at the same time by one water circuit 51.

The above-mentioned thread can be moved by bringing the suction port of the water circuit 51 close to the thread B supported by the air circulator 50, 50 '.

This uses the feature that the suction force of the water circulator 51 is significantly larger than the suction force of the air circulators 50 and 50 '.

And as the above-mentioned water surfer 51, what is shown in FIG. 6 is mentioned, for example.

In the drawing, "52" is a suction nozzle, "53" is a high pressure water injection hose, and the right end portion 53a is connected to a water supply source (not shown).

Water flows as indicated by the arrow in the figure, and acts to enter the thread by the spray suction force of water at the tip suction port 52a of the suction nozzle 52.

The thread is sucked into the suction port 52a and moves with the water into the hose 54 to enter the reservoir (not shown).

The above-mentioned water circuit 51 has an excellent property of imparting high tension to the yarn with lower energy consumption than the air circus 50 and 50 ', and the rotational speed of each roll of the apparatus is 400 m / min or more. Transfer of the yarn B from the air circulator 50 in the state of maintaining the high speed to the water sucker 51 and transfer of the yarn A from the air circulator 50 again while the yarn B is sucked. Can be performed simply.

In addition, the suction nozzle 52 of the water circulator 51 described above may be made of a low friction member.

In addition, in the above-mentioned manufacturing method, the yarns (A) and (B) run side by side on the fourth Godet roller 34, so that both yarns (A) and (B) come into contact with each other due to the fluctuation of the yarn, which is likely to cause lint.

By the way, both the yarns (A) and (B) must run side by side at a predetermined interval on the fourth Godet roller 34, but it is very difficult to hang the two yarns (A) (B) in close proximity to each other.

However, as shown in FIG. 7, when the auxiliary device 60 is installed on the way of the thread A from the second Godde roller 32 to the fourth Godde roller 34, the thread ( A) (B) It is good to make the thread walk in the overlapped state, and after the thread is finished, the length of the thread (A) should be set aside so that the length of each thread does not touch each other.

That is, the auxiliary device 60 described above and the guide regulation guide 62 of the thread in which a plurality of rod-shaped body 61 abutting from each side of the thread (A) of several strands running side by side as shown in FIG. A solenoid 63 is connected to the lower end side of the thread guide regulating guide 62 and moves the thread guide regulating guide 62 described above to the left and right with respect to the thread length by a predetermined stroke.

And "64" is a compression spring for return.

The position of the dense bar-shaped body 61 described above is changed as follows by the operation of the solenoid 63.

That is, in the state in which the solenoid 63 does not operate, as shown in FIG. 9A, the rod-shaped body 61 has a path along which the thread B wound on the fourth Godet roller 34 goes along the length of the thread A. It is located at the position which regulates the seal A so that it may not contact each other.

In the state where the solenoid 63 is operated, as shown in FIG. 9B, the rod-shaped body 61 is formed so that the rod A overlaps the length of the yarn B wound on the fourth Godet roller 34 of the yarn A length. ) Is in a position to regulate.

Therefore, when the thread is mounted by installing the auxiliary device 60, the solenoid 63, which is the auxiliary device 60, is operated to set the rod-like body 61 to the position shown in Fig. 9B, so that both chambers A and B are mounted. I can hang a thread in the state that the length of overlapped.

That is, the above-mentioned yarns (A) and (B) are overlapped one by one on the Godet roller 34, and it is easy to introduce the yarns (A) and (B) into one pair by one into the interface nozzle 40. Become.

After hanging the thread, the solenoid 63 is stopped at this time, and the rod-like body 61 is returned to the position shown in FIG. 9A, and the thread A is transversely oriented in the fourth direction. It can be put in between the path | route of the thread B on the detro roller 34, respectively.

This state is shown in the eleventh degree.

Therefore, at the time of operation of the apparatus, the two chambers A and B interfere with each other because the two chambers A and B are arranged to run side by side on the fourth Godet roller 34 without being in contact with each other. No fluff occurs.

12 shows an apparatus for manufacturing a yarn to be used in another embodiment of the present invention.

The apparatus for manufacturing this yarn is basically the same as the apparatus shown in FIG. 1, but in this apparatus, the radiation head 1 common to the left and right radiation stretching apparatuses is a pellet tank 10, 10a and a spinning nozzle 25 ( 25a) (however, this figure is typical).

In the drawing, the molten polymer A is supplied from the melt extruder 11 on the left side, and the molten polymer B is supplied from the melt extruder 11a on the right side.

The above-described spinning head 1 is formed by combining a plate-shaped spinning head body 2 and a distribution block 3 installed and fixed in the center of the upper surface of the spinning head body 2 as shown in FIGS. 13A and 13B. It is.

And the distribution block 3 installed is fastened to the spinning head main body 2 with four bolts 4, and is fixed.

And "5" is a handle of the distribution block (3).

On the rear side of the above-mentioned radiation head main body 2, there are two introduction holes 6a and 6b extending from the rear side to the inside of the main body 2 only by a certain depth and opening perpendicularly therefrom. The pipes extending from the left and right pellet tanks 10 and 10a are formed in communication with these holes 6a and 6b, respectively.

In addition, four discharge holes 7a, 7b, and 7c which extend the inside of the main body 2 to a predetermined depth on the front side of the above-mentioned radiating head main body 2 and rise at right angles therefrom and are opened on the upper surface of the main body 2. 7d is formed, and among these holes, two holes 7a and 7b on the left side communicate with the radiation nozzle 25 of the radiation drawing apparatus on the left side through a pipe, and two holes 7c on the right side. (7d) communicates with the radiation nozzle 25a of the radiation stretching apparatus on the right side through the pipe (see FIGS. 12 and 15).

As the distribution block 3 fixed to the upper surface of the above-mentioned spinning head body 2, for example, two kinds of things 3a and 3b shown in Figs. 14A and 14B can be mentioned.

All of these distribution blocks 3a and 3b have openings 8a and 8b formed at positions corresponding to the introduction holes 6a and 6b which are opened on the upper surface of the radiation head body 2, and the radiation head body The openings 9a, 9b, 9c and 9d are formed at positions corresponding to the discharge ports 7a, 7b, 7c and 7d which are opened on the upper surface of 2).

In the distribution block 3a of FIG. 14A, the opening 8a and the openings 9a and 9b communicate with each other, and the opening 8b and the openings 9c and 9d communicate with each other.

Therefore, the distribution block 3a is fixed to the spinning head body 2 to introduce the molten polymer A in the introduction hole 6a and to introduce the molten polymer B in the introduction hole 6b. As shown in FIG. 15, the molten polymer A is supplied to the spinning nozzle 25 of the spinning apparatus on the left side and the molten polymer B is supplied to the spinning nozzle 25a of the spinning apparatus on the right side.

Thereby, the yarn which consists of a polymer (A), and the yarn which consists of a polymer (B) can be discharged | pulverized, it winds up, and another polymer mixed fiber can be obtained.

In the drawing, the solid line represents the flow path of the molten polymer A and the plate line represents the flow path of the molten polymer B.

On the other hand, openings 8b, 9a, and 9c are connected to the distribution block 3b of FIG. 14b, and 8b, 9b, and 9d are connected to each other.

Accordingly, the distribution block 3d is fixed to the spinning head body 2 to introduce the molten polymer A in the introduction hole 6a and the molten polymer B in the introduction hole 6b. As shown in the figure, part of the molten polymer (A) (B) is supplied to the spinning nozzle 25 of the spinning apparatus on the left side, and the remaining molten polymer (A) (B) is feeding to the spinning nozzle 25a of the spinning apparatus on the right side. Supplied.

That is, melt polymers (A) (B) of different types are discharged simultaneously to the same nozzle hole at predetermined ratios in the spinning nozzles 25 (25a) of the left column.

In this way, the yarn made of polymer (A + B) can be spun, spun and wound with the right and left apparatuses to obtain a conjugated yarn.

Therefore, according to the present apparatus, the two kinds of distribution blocks 3a and 3b can be manufactured simply by appropriately exchanging, so that a small quantity production can be realized efficiently.

Further, since the molten polymer is supplied to the left and right spinning apparatuses in one spinning head 1, the quality of the left and right yarns to be spliced is stable and a uniform yarn can be obtained.

And in the above-mentioned embodiment, the method of manufacturing the yarn using two types of molten polymer (A) (B), but the present invention can be applied to the case of using three or more types of molten polymer.

In addition, in the above-described embodiment, the polymer is supplied to the radiation stretching apparatus parallel to the left and right by one spinning head 1, but the simultaneous supply to the pair of the radiation stretching apparatuses as well as the one or more pairs of the radiation stretching apparatuses The head may be used.

In this case, it is necessary to increase the number of devices for simultaneously supplying the molten polymer flow paths formed in the distribution blocks 3a and 3b.

The shape of the spinning head 1 and the flow channel formation method of each molten polymer are not limited to the above-described embodiments, and can be appropriately designed.

For example, the spinning head 1 may be one that is a combination of the two methods shown in FIGS. 17A and 17B.

That is, the distribution blocks 3a and 3b shown in FIG. 14 have a difference in height between the two flow paths extending in the horizontal direction so that the flow path of the molten polymer A and the flow path of the molten polymer B do not intersect. In this distribution block (3a) and (b) of FIG. 17, the difference between elevations is not provided in the two flow paths extending in the horizontal direction so as to be formed obliquely so as not to intersect the flow paths on the discharge side in the block.

As described above, the manufacturing method of the other shrinkage blending yarn of the present invention is not to supply the raw material polymer from the same weight, but to supply the raw material polymer from each of the two different weights to obtain different shrinking blending yarn. Conditions or combinations of different thread sections can be installed separately, and different shrinkage blending yarns with different heat shrinkage characteristics can be obtained.

In addition, it is not necessary to use a special roller combination and has the advantage that the adjustment is simple.

Then, by using the special spinning head of the present invention, simply selecting two types of distribution blocks constituting the inside of the spinning head, the device is manufactured for the manufacture of two polymer blended yarns or two kinds of yarns braided with two different yarns. It can divide and use for manufacture of the conjugate chamber which consists of a polymer.

Therefore, a single facility in which a plurality of spinning apparatuses are paralleled can be divided into the production of other polymer blends and the production of conjugates, so that a small quantity production can be efficiently performed.

In addition, since the polymer is supplied to the radiating apparatuses adjacent to each other collectively by one common radiating head, the quality of the yarn to be spliced is stabilized and a homogeneous yarn can be obtained.
