Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a continuous drawing and splitting method and apparatus for continuously producing drawn monofilament yarns or multifilament yarns from undrawn multifilament yarns of 8 synthetic fibers. It is related to.

(Prior art) Conventionally, when producing fine denier monofilament yarn or multifilament yarn of synthetic fibers such as polyamide and polyester, one undrawn multifilament yarn is drawn and once wound around a bobbin, and the obtained drawn multifilament yarn is drawn. A method has been adopted in which yarn is split into monofilament yarn or multifilament yarn using a continuous or double splitting device. This method has low productivity because the drawing step and the splitting step are not continuous. For this reason, various methods have been proposed for the purpose of producing fine denier monofilament yarns or multifilament yarns of synthetic fibers with good productivity.

First, in Japanese Patent Publication No. 4]-6286, an undrawn multifilament yarn is drawn out in an untwisted state and stretched, and then the drawn multifilament yarn obtained is transferred to a roller guide and split into multiple fibers on the roller guide. A method has been proposed in which monofilament yarn is wound using a plurality of winding devices. In this method, when dividing a drawn multifilament yarn, the monofilament yarn is successively separated from the drawn multifilament yarn, and as the monofilament yarn is successively separated, the remaining drawn multifilament yarn passes through a guide. As the number of monofilaments increases sequentially, a difference in tension occurs between the monofilament systems separated, resulting in a problem of variations in yarn quality. In addition, since the running tension of the filament yarn at the splitting point, so-called splitting tension, and the winding tension are linked, 1
Fluctuations in the splitting tension may directly affect the winding tension, resulting in poor package shape, resulting in poor unwinding of the package in the subsequent process, or lowering the winding tension to obtain a good package shape. If this is attempted, the splitting tension cannot be lowered, resulting in the problem of filament breakage at the splitting point.

Furthermore, Japanese Patent Application Laid-Open No. 48-41018 discloses that a traveling multifilament yarn being drawn is separated into a plurality of monofilament yarns using a composition guide, and then once bundled,
A method of winding using a plurality of winding devices has been proposed. This method requires high tension (usually 1.5 to 3.0 g/
d) Since the multifilament yarn under such conditions is passed through a composition guide and a convergence guide, which are yarn abrasive bodies, the multifilament yarn may be damaged, resulting in a decrease in the quality of the resulting monofilament yarn, or the filament may break. This has the problem of causing problems.

(Problems to be Solved by the Invention) The present invention solves the above problems, effectively splits multifilament yarn with high and stable splitting tension, and splits the obtained monofilament yarn or multifilament yarn. It is an object of the present invention to provide a method and an apparatus for stably winding with an optimum winding tension.

(Means for solving problems) The present invention has a 9-order configuration.

(1) Undrawn multifilament yarn is drawn out from a package of undrawn multifilament yarn wound in a substantially non-twisted state using a drawing roller, and is drawn out in a non-twisted state between the drawing roller and the final drawing roller in stages or in multiple stages. In the continuous drawing and weaving method, the drawn multifilament yarn is drawn in stages to form a drawn multifilament yarn, and the drawn multifilament yarn is continuously divided into monofilament yarns or multifilament yarns and wound without being wound. Separation into multiple monofilament yarns or multifilament yarns is performed between the drawing roller and a fixed separation point roller disposed downstream of the final drawing roller, and the separated filament yarns are transferred downstream of the fixed separation point roller.

A continuous drawing and splitting device comprising a winding device.

A feature of the method of the present invention is that the final stretching roller and the dividing point fixing roller are arranged downstream of the final stretching roller and the dividing point fixing roller at equal intervals and satisfy the above formula (a). The drawn multifilament yarn is split by setting the optimum splitting tension between a plurality of bow-taking rollers arranged in a manner similar to the above, and the plurality of filament threads separated into one part are individually separated by the taking-off roller. The aim is to optimize the dividing tension by independently changing the circumferential speed of a plurality of bowing rollers, and to connect the dividing point on the dividing point fixed roller and the plurality of pulling rollers. It is possible to prevent an increase in variation in the splitting tension between the plurality of filament yarns split between the reroller and the filament yarns.

The feature of the apparatus of the present invention is that a separating point fixed roller consisting of a free roller is arranged downstream of the final stretching roller, and the separating point fixed roller is arranged downstream of the separating point fixed roller at equal intervals and satisfies the above formula (a). A plurality of take-up rollers are provided, and the drive sources for the take-up rollers and the winding device are made independent. In the device of the present invention, the one-minute point fixing roller is a roller that rotates following the running filament yarn due to the running tension of the running filament yarn, and is a so-called free roller.1 It is a normal low-torque bearing type or air bearing type. A roller is used. The plurality of take-up rollers are arranged at equal intervals so as to satisfy the above-mentioned formula (a) regarding the 1-minute point fixing roller.

The take-up rollers have a drive source that is common but different from that of the final stretching roller and the winding device.

The optimum circumferential speed is set regardless of the circumferential speed of the final stretching roller or the winding speed.

Next, the method and apparatus of the present invention will be specifically explained based on one drawing.

FIG. 1 is a diagram showing an embodiment of the apparatus of the present invention, where Y is an undrawn multifilament yarn, y is a drawn multifilament yarn, yl to yn are monofilament yarns or multifilament yarns that have been split after being drawn, 1 is a package made of undrawn multifilament yarn Y wound in a substantially untwisted state; 2 is a pull-out roller for pulling out the undrawn multifilament yarn Y from package 1 in an untwisted state; 3
is a drawing bin, 4 is a drawing roller that draws the undrawn multifilament yarn Y between it and the drawing roller 2; Separating point fixed rollers 61 to 60 consisting of free rollers for separating fibers between the separating point fixed rollers 5 are arranged at equal intervals so as to satisfy the above formula (a) with respect to the separating point fixed roller 5. The take-up rollers 171 to 7n that individually take up the monofilament yarns or the multifilament yarns y1 to yn are respectively disposed corresponding to the take-up rollers 61 to 6n, and are winding devices that individually wind the filament yarns y1 to yn. In addition, in this device, the distance between the centers of each of the plurality of take-up rollers 61 to 6n arranged at equal intervals in the horizontal direction from the first to the nth is 10-
Although it depends on the roller diameter, it is usually 150 to 300 mm, and the number n of take-up rerollers is preferably about 2 to 15.

The method of the present invention uses an apparatus as shown in Fig. 1, in which undrawn multifilament yarn Y
is untwisted and pulled out from the package 1 by the pull-out roller 2, supplied to the stretching area in an untwisted state, and stretched between the pull-out roller 2 and the stretching roller 4 via the stretching bin 3. The obtained drawn multifilament yarn y is supplied to a splitting point fixed roller 5, which is a free roller disposed downstream of the drawing roller 4, and is divided into two or more drawn monofilament yarns or multifilament yarns on the splitting point fixed roller 5. The filament yarns are divided into filament yarns y1 to yn, and then taken up by take-up rollers 61 to 6n.
will be collected individually by The circumferential speed of the take-up straws 61 to 6n is set to be equal to or higher than the circumferential speed of the drawing roller 4, that is, the drawing roller 4 and the take-up rollers 61 to 6
A stretch state with a stretch rate of 0% or more is created between the fibers and n, and the 1-minute fiber tension is improved.

In the method of the present invention, the one-minute fiber point fixing roller 5 is a so-called free roller that rotates following the running filament yarns y1 to yn due to the running tension of the running filament yarns y1 to yn. It rotates and always fixes the separating point on the roller 5, making it possible to stably separate the fibers. moreover.

In the method of the present invention, the one-minute fine point fixing roller 5 is
a) Since the take-off rollers 61 to 6n are arranged so as to satisfy the formula, the filament yarns y1 to yn between the dividing point on the one-minute split point fixing roller 5 and the take-off rollers 61 to 6n
The running tension difference is small, and the variation in the dividing tension between the four divided filament yarns y1 to yn does not increase.

In the present invention, the take-up rollers must be arranged at equal intervals so as to satisfy the above formula (a) with respect to the bifurcating point fixed roller, and the take-up roller and the split point fixed roller must be arranged at equal intervals. If the relationship of the arrangement positions does not satisfy the above formula (a), the dispersion of the splitting tension will increase between the filament yarns divided into one filament yarn, so that a filament yarn of uniform quality without any dispersion between the yarns will be obtained. I can't.

Next, the filament yarns y1 to yn are separated on the two-dividing point fixed roller 5 and taken off by the take-up rollers 61 to 6n.
is a winding device 71 disposed corresponding to the take-up reroller.
~7n individually wound. At this time, the winding speed of the first winding device 71-7n is set to be equal to or lower than the peripheral speed of the take-up roller 61-6n, that is, between the take-up roller 61-6n and the winding device 71-7n. is in a relaxed state with a relaxation rate of 0% or more, and the optimum winding tension can be obtained.

3. The undrawn multifilament yarn in the present invention is made of a polymer such as polyamide or polyester, and is substantially untwisted.

In the present invention, when drawing the undrawn multifilament yarn, the number of drawing steps is one or more. Stretching methods include (1) a cold stretching method using a normal stretching bin or without using a stretching bin, or contact heating means such as a hot pin, hot plate, or hot roller, or non-contact heating means such as a sleeve heater or steam jet. A hot drawing method can be employed, and if necessary, the filament yarn can be heat-treated using a hot roller or the like.

In the above explanation, as shown in FIG. 1, an example was shown in which the fibers are separated from one stretching roller 4 by one separating point fixed roller 5, and the fibers are taken up by taking-off rerollers 61 to 6n. As shown in FIG. 2, the fibers are separated from one stretching roller 4 by a plurality of separating point fixed rollers 5, and a plurality of separating point fixed rollers 51 to 5 are separated.
A plurality of take-up rollers 6 individually arranged corresponding to m
You can also pick it up at 1-6n.

4 As detailed above, 1. In the present invention, a take-up roller is disposed between the final stretching roller and the winding device, and the 1-fiber splitting area and the winding area are completely separated. The level of the splitting tension in the splitting zone and the level of the winding tension in the winding zone can be set independently to the optimum values. It becomes possible to obtain a good package in the form of a single winding by winding monofilament yarn or multifilament yarn at an optimal winding tension. And 1
Since a guide or the like is not used during fiber separation, filament breakage does not occur. Then, the difference in running tension of the filament yarn between the dividing point on the 9-minute point fixing roller and the plurality of take-up rerollers becomes smaller, and the variation in the dividing tension between the multiple filament yarns separated into 9-minute points increases. Therefore, the obtained filament yarn does not have any variation in yarn quality or decrease in its quality.

(Example) Hereinafter, the present invention will be specifically explained with reference to Examples.

Note that the 9-minute a-manufacturing performance was evaluated by the ratio (%) of the number of weights at which a full package could be obtained per number of weights to be wound together to the number of weights to be wound together. The winding form of the package is ○: good;
Evaluation was made in three stages: Δ: Slightly poor, ×: Poor. In addition, yarn unevenness (C%/U%) was measured using a Nippon Keiki Kogyo Evenness Tester KBT-80 at a yarn speed of 2 (1 m/min, half inert).Strength, elongation and heat The water shrinkage rate was measured according to the method of JISL 1 (113).Furthermore, the variation in 1-minute fiber tension, fineness 1 strength, and elongation between winding weights was evaluated by the rate of variation of each measured value.

Separation tension, fineness 2 Variation rate of strength or elongation - [(Standard deviation of measured values regarding the weight to take up the bundle)/(Average value of the measured values regarding the weight to take up the bundle)) X100 (%) Example 1 Nylon 6 The chips were melt-spun from a spinneret with seven spinning holes to obtain an undrawn multifilament yarn of nylon 6 wound in a substantially untwisted state, which was then transferred to a continuous drawing and splitting apparatus (n = 7) was used to draw and separate the fibers, and
Seven monofilament threads of d were obtained. When performing stretching and splitting, the number of stretching rollers is 1, the number of rollers fixed at the splitting point is 1, and the number of take-up rollers is 7 (number of winding weights is 7), and these are combined into 1 unit for a total of 10 units (1 unit for winding up). Stretching and splitting was performed using a spindle (number of weights: 70).

When stretching, the stretching method was changed to non-heated stretching pin 3 (cold stretching method 1 using experiment N (1, 1) with a surface temperature of 145 ~
Hot drawing pin 3 heated to 155°C (Actual MNo. 2~
4, 7, and 8) and a hot stretching method using a single-sided or double-sided hot plate heated to a surface temperature of 150°C (Experiment No. 5 and 6).

As stretching conditions, the peripheral speed of the stretching roller 4 (i.e., stretching speed) is 300 m/min, and the ratio between the peripheral speed of the drawing roller 2 and the peripheral speed of the stretching roller 4 (i.e., the stretching ratio) is 4.6.

/3f multifilament yarns were obtained. However, when performing stretching and splitting, the number of rollers fixed at the splitting point is set to 1 for each stretching roller.
The number of take-up rollers was 4 (the number of winding weights was 4), and this constituted one unit, and drawing and separation was performed using a total of 20 units (total number of winding weights: 80).

When stretching, the stretching method was changed to a cold stretching method 9 using unheated stretching pins 3 (experiment No. 9) at a surface temperature of 15 (
Hot stretching bottle 3 heated to 1°C (Experiment No. 10
) and a hot stretching method using a single-sided or double-sided hot plate (Experiment No. 11 and 12) heated to a surface temperature of 150°C.

The stretching conditions such as the stretching speed and the stretching ratio were the same as in Example 1 (Experiment Nos. 9 to 12).

As the fiber separation conditions, the stretching roller 4 and the take-up rollers 61 to 6

When winding, a ring type twisting winder 71 to 74 equipped with a traveler is used, and a take-up roller 61 is used as one winding condition.

The above results are shown in Table 1.

Experiment Nos. 1 to 12 satisfied the constituent requirements of the present invention.

It was possible to form a good package with good splitting operation and a five-wound configuration.The resulting filament yarn had small variations in yarn quality between winding spindles.

-21 = Comparative Example I In the same manner as in Example 1, undrawn nylon 6 multifilament yarn was drawn and split into 30 d monofilament yarn 7.
I got the book. During stretching and splitting, the number of rollers fixed at the splitting point is set to 1 for each stretching roller. The number of take-up rollers was set to 7 (the number of winding weights was 7), and this was regarded as one unit, and drawing and separation was carried out using a total of 10 units (total number of winding weights of 70).

When stretching, the stretching method was changed to cold stretching method 1 using an unheated stretching bin 3 (experiment No. 1.3) with a surface temperature of 1.
Hot drawing pin 3 heated to 50°C (Experiment No. 14)
Two hot stretching methods were used.

The stretching conditions such as the stretching speed and the stretching ratio were the same as in Example 1 (Experiments N013 and 14).

When separating the fibers, the distance between the center of each of the first to seventh take-up rerollers 61 to 67 arranged at equal intervals in the horizontal direction is set to 190 mm, and the separating point is set from the direction in which the take-off rollers 61 to 67 are arranged. The distance H to the fixed roller 5 is 600 mm,
[:H/Lx (n-1)]-0,53, that is, a condition that does not satisfy the constituent requirements of the present invention.

2. As fiber splitting conditions, 1 stretching roller 4 and take-up rollers 61 to 6

d) (Experiment No. 13 and 14).

When winding 1. Ring type twisting winding machines 71 to 77 equipped with travelers are used to take up the winding roller 6 as one winding condition.
The mechanical relaxation rate between 1 to 67 and the winders 71 to 77 was 8.0% (Experiments N013 and 14), and the winding amount of the bathoke was 1. It was set as Okg.

The above results are shown in Table 2.

Experiment Nos. 13 and 14 that do not satisfy the constituent requirements of the present invention
Although the single-fiber operation was good and a good single-wound package could be formed, the obtained filament yarn had a lot of variation in yarn quality between winding spindles.

Comparative Example 1 Nylon 6 chips were melt-spun from a spinneret with 7 spinning holes to obtain an undrawn nylon 6 multifilament yarn wound in a substantially untwisted state, and this was passed through a normal supply roller (see Fig. 1). After stretching using a stretching device consisting of a drawing roller (corresponding to the drawing roller 2), a stretching pin, and a stretching roller (corresponding to the stretching roller 4 in FIG. 1), the fibers were subsequently split to obtain seven monofilaments of 30 d. .

When splitting the fibers, the one-fiber splitting method is changed to a method that does not use the splitting point fixed roller 5, that is, the drawn multifilament yarn y is directly transferred from one drawing roller to a plurality of parallel guiding rollers (
The monofilament yarn is supplied to a ring-type yarn winding machine equipped with a traveler (corresponding to take-up rollers 61 to 67 in FIG. 77) was adopted.

The number of guide rollers was set to 6 (the number of winding weights was 7) for the number of drawing rollers, and this constituted one unit, and a total of 10 units (the number of winding weights was 70) were used to carry out drawing and fiber division.

When stretching, the stretching method was changed to an unheated stretching pin (Experiment N
Cold drawing method using 15 and 16) 1 surface temperature
There were two hot stretching methods using hot stretching pins (experiment No. 013) heated to 50°C.

The stretching conditions such as the stretching speed and the stretching ratio were the same as in Example 1 (Experiment Nos. 15 to 17).

The stretch rate corresponding to the stretch rate between the stretching roller 4 and the Yudori rerollers 61 to 67 in Example 1 as a fiber splitting condition is mechanically is 0% (Actual NN015 ~
17) However, since the monofilament yarn slips on the two drawing rollers, it is essentially in a relaxed state. Therefore, in this method, the splitting tension is linked to the winding tension, so when setting the 1-minute fiber tension, the splitting tension can be adjusted to approximately 0.2 g/d by changing the weight of the traveler (Experiment N
o, 15), about 1. Og/d (experiments Nα16 and 17
) was set.

As winding conditions, the mechanical relaxation rate between the drawing roller and the twisting machine was 8.0% (Experiment Nos. 15 to 17).

The volume of the package is 1. It was set as Okg.

The above results are shown in Table 2.

In experiment Nα15, when the 1-minute fiber tension was set to approximately 1.0 g/d, the 1-minute fiber tension was linked to the winding tension, so the winding tension became too high and the package was wound tightly, causing continuous winding. could not be done.

5-Also, in Experiment Nos. 16 and 17, the traveler was changed to a lighter one to lower the winding tension and improve the winding form of the package, but the 1-minute fiber tension was as low as about 0.2 g/d. Problems such as the filament yarn being cut in the 1-minute fiber region, or the filament yarn passing over to an adjacent spindle and being wound around the roller occurred, resulting in a decrease in 1-minute fiber operation.

6- Table 2 (Effects of the Invention) According to the method and apparatus of the present invention, high and stable splitting tension can be achieved when continuously producing drawn monofilament yarn or multifilament yarn from undrawn multifilament yarn of one synthetic fiber. The multifilament yarn can be divided well, and the obtained monofilament yarn or multifilament yarn can be stably wound with an optimal winding tension.

The resulting filament yarn has small variations in yarn quality between each winding spindle.
