Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for producing a polymer mutual array in which polymers are arranged in the axial direction. More specifically, it describes a method for producing a polymer mutually arranged body having a unique structure in which two polymeric AB components are mutually arranged, and another C component layer intersects and intervenes so as to divide the AB2 component layer. This is related to the device.

Polymer mutual arrays are known as sea-island composite fibers in the form of fibers, and when divided or one component removed, they can be used as ultrafine fibers for various artificial leathers, waterproof high-density woven and knitted fabrics, and fabrics. It has many useful uses such as woolen fabrics, tricots, filters, high-grade strings, fiber-reinforced fibers, and silk-like woven and knitted fabrics. In addition, although the film form has many uses, such as optical applications where it can be used as an image guide by simply stacking it, polarizing plate applications, easily splittable films, and highly reflective road sign applications, it is easy to No method for manufacturing array fibers or films has been provided.

An object of the present invention is to provide a method for easily producing a polymer mutual array, and in particular, to easily and highly increase the number of components corresponding to island components, and in particular, to increase the ratio of island components. The purpose is to significantly increase economic and industrial value. A further object of the present invention is to obtain fibers suitable for stably and reliably obtaining ultrafine fibers over a long period of time even when the number of island components is extremely increased.

A further object of the present invention is to provide a fiber or film having a sea-island structure, in which the islands further have a sea-island structure, which is an extremely high degree of structure.

Another object of the present invention is to provide a splittable fiber in which one component further has a polymer mutual array structure. Furthermore, it is an object of the present invention to provide a method that has all the above-mentioned structures and has excellent spinning stability.

Other purposes will become apparent from the description provided below.

Now, if we look at the conventional technology, we can see that there are methods and devices for obtaining fibers with a polymer mutual array structure: 18369-18369, 13208-13208, 47-
There are 26723. This method is extremely effective as it increases the ratio of island components, ensures reliable island arrangement, high spinning stability, and extremely good controllability, but it also extremely increases the number of island components. At the same time, it is difficult to create pores from a single cap, which inevitably leads to high costs.

On the other hand, the special public authorities 1973-3505, the 44-889 special public authorities,
Tokusho 43-19604, USP3051453, etc., first of all
The AB2 fluid is placed in an alternating laminar flow (in the form of ABABABAB...) or similar relationship, and then this fluid is passed through a sand layer or through a wire mesh or gauze to disrupt and split the laminar fluid, and to In general, it is around 50%, but it varies somewhat due to viscosity difference, interfacial tension, etc.), and it has a dispersion-non-dispersion relationship, just like polymer blend spinning, and has a considerable degree of dispersion depending on the spinning hole. A spinning method has been provided that has an alignment relationship. The biggest drawbacks of these methods are that the spinning conditions are just like those in polymer blend spinning, where the streamlines are disturbed from time to time, making the spinning unstable, and the spinning must be performed with strong wind (quenching). There are serious problems such as the inability to perform high-speed (take-up) spinning, poor drawability of yarn spun with strong wind, inability to draw at high magnification, poor yarn properties, and the formation of drip-like yarns that cannot be spun. It had drawbacks. In particular, the disadvantages of not being able to obtain a high ratio of island components, differences in fiber cross section and fiber quality among the multiple discharge holes, and unstable spinning were disadvantages that could be said to be fatal from an industrial perspective. . Patents such as Japanese Patent Publication No. 47-15530 disclose a spinning method and apparatus having a large number of mixing channels, but when all the components are layered, the distribution of each component in the cross section is sometimes It changes from moment to moment,
The present invention still contains the objectives that must be solved, such as the large variation among fibers, the inability to control the number of island components, and the inability to obtain a high island ratio.

The present invention provides a method and apparatus for producing a polymer mutual array without these drawbacks, as well as a fiber with a novel array structure.
For example, it is easy to achieve a large number of islands with 100 to 100,000 islands, and at the same time, it is easy to achieve an extremely high island ratio.
At the same time, it has a simple discharge structure that is easy to make, 1/10
It is easy to make ultra-fine continuous fibers of ~1/10000 denier (100 microdenier), and at the same time, the structure and method have a stable flow, resulting in stable spinning, stable discharge comparable to that of a single component, and at the same time the long cross-sectional length (fiber A discharge structure that is stably connected in the axial direction, with a distribution of high island sub-sections in which many islands are surrounded by many other islands, which are surrounded by the same or other sea components. Fibers with a structure that is not exposed on the surface of an island component, furthermore, fibers that form an island component in a polymer mutual array structure having a sea-island cross section, and furthermore, fibers that are separated by other island components or the same component. It is an object of the present invention to provide a separable type conjugate fiber or one in which the surface of the composite fiber has a sandwich structure film or the opposite structure, and to achieve these desired effects.

The gist of the invention is as described in the claims.

Now, in order to make it easier to understand, an example will be given and explained below.

Figure 1 shows a three-component composite fiber or film (including ribbon-like) obtained by the present invention, in which in the fiber cross section, AB2 components are alternately arranged in large numbers and interposed with each other, and the A component layer and An example of a cross section of a polymer mutually arranged fiber in which the C component (including the case where it is the same as the A or B component) is interposed in a layered manner at the interface of the B component layer, and such relationships form multiple layers.
1> (hereinafter, numbers in the figures are indicated by <>). This may be a film (including a ribbon) extending in a certain direction. This is only a matter of drawing; if you stretch it out horizontally and look at it, it looks like a film or ribbon.

In other words, the A component and the B component overlap (ABABABAB...) and are interposed by a large number of C components so as to cut the interface.
It does not have a multilayer structure of ABCABCABC... in which the components and B components are all arranged in layers like the C component.

The interface between the A and B components is generally parallel, as described later, but the smaller and thinner the A component is, the more the viscosity and difference between the A and B components, the interfacial tension, and their Due to differences, etc., the A component becomes smaller and becomes elliptical or round. Further, the A component and the B component may be reversed. This does not impede the effectiveness of the present invention, but rather brings about favorable results when ultrafine fibers are aimed.

In principle, the A and B component layers or the C component layer can be arranged in parallel, but this is generally not the case. This is because viscous fluids, such as polymer melts, flow faster in the center of the tube, and the closer they get to the walls, the slower the flow. The cross-sectional distribution of the flow in a circular tube is said to be parabolic. Furthermore, when the polymer is discharged from the discharge hole and taken out at a constant high speed, the central part of the hole continues to be replenished with polymer one after another, but the part near the hole wall is not sufficiently replenished. It will be stretched. Therefore, that part maintains a thin and small distribution form, and the central part becomes thick. In other words, if we focus on the form of the island component (referred to as A), the central part becomes thicker and the outer periphery becomes thinner. Figure 2 is a schematic enlarged view of a part of Figure 1, and shows the shape of the AB component. It shows the alternating arrangement layers <2> and <3> and the laminar flow <4> of the C component obtained by dividing them. The reason why such a state is formed will be shown in a later principle diagram. To give an example of what kind of characteristics such a fiber has, if A,
If a polymer is selected in which components B and C are non-adhesive, that is, they can be separated by adding physical or chemical means, component C and components A and B are first separated after fiber or film formation. be able to,
Furthermore, the A component and the B component can be separated into fine fibers. The number of layers and the total number can be numerous. A preferred example of the separation means is to apply a water jet to any processed product of such polymeric interlayer fibers by known means (such as a thin, strong, needle-like jet of water, e.g.
7274, 47−18069, 48−13749, 57−59348, 44−
22230, 57-58463, etc.). Furthermore, if component B can be dissolved and removed using a solvent or a decomposing agent, ultrafine fibers of component A can be obtained. Furthermore, if both the C and B components are removed simultaneously, ultrafine fibers consisting only of the A component can be obtained.

By removing only the thin striped portions of component A or component B exposed on the surface, it is possible to obtain highly colored fibers as long as the thinness is appropriate.

Figure 3 shows that in one fiber cross section <5>, a large number of island components A are dispersed and arranged along the layer arrangement, and the fiber is a polymeric mutual array fiber with a high number of island components, that is, sea islands. It is a composite fiber. Component B is a sea component. This fiber is obtained by making component C the same as component B in FIG.
If the viscosity of the component is higher than that of the B component, the A component will be rounded. The morphology of such island components is
Suitable for those with a high number of islands such as 100 to 100,000, and even for those with extremely high island ratio.
It can even be made to have an extremely low island ratio.
According to the present invention, these materials can be obtained stably, stretch well, and have excellent molecular orientation of the island components.

FIG. 4 is a longitudinal cross-sectional example of the mutually arranged polymer of the present invention, showing that each component is well arranged in the fiber axis direction and the film axis direction. Especially in Figure 3.
The AB components are arranged substantially parallel to the fiber axis direction. This will be better understood if you compare it with Figures 3 and 4. However, in this case, the A component is represented by a line. <7> is a general symbol indicating omission of an intermediate portion.

FIG. 5 shows that the polymer mutual array obtained by the present invention is further coated with one more component <11> (component D), and one of the components A or B (in this figure, <
10>) indicates that the fibers are not substantially exposed on the outer periphery of the fiber cross section. When the A component is an island component, the D component is preferably the same as the sea component of the B component. Not only does this have the effect of preventing component A from being peeled out of the fiber, but if component B is removed, a large number of bundles of ultrafine fibers of component A can be obtained at once.

Of course, depending on the purpose, component D may be common to component A, or may be a different polymer from AB.
This can be said to be a core-sheath type composite fiber in which the core is the mutually arranged polymer obtained according to the present invention and the D component is the sheath. This type is particularly effective in preventing separation of the A component from the B component when the number of divisions of the A component is small and the A component is easily separated from the B component. In addition, in the case of Fig. 5 as well as in Fig. 3, the C component is the same as the B component (=B),
The C component intersects and interposes so as to cut the AB component layer.

FIG. 6 shows a sea-island composite fiber in which the AB component is an island component <13> and the D component <14> is a sea component.
The island component consists of AB and C (=B) as in Figure 3,
It is a high-grade fiber that forms a polymeric mutual array in which C component layers intersect and intervene so as to cut AB component layers, and can be referred to as island-in-sea composite fiber <12>. In particular, the island component A within the islands is extremely highly dispersed and is suitable for obtaining bundles of ultrafine fiber bundles. In reality, they are too small to be shown in the figure, and there are many of them, but in the figure they are shown as thick, rough dots for easy understanding. Of course, each component of this fiber is arranged in the fiber axis direction.

FIG. 7 is an example of a splittable composite fiber. In this fiber cross section <15>, a polymer mutual array is used in which the components to be divided <18>A and B components have a high cross-sectional distribution as shown in FIG.
This is an example of dividing by . That is, as in FIG. 3, it consists of AB and C (=B), and the C component intersects and intervenes so as to divide the AB component layer.

Moreover, FIG. 8 is an example of a hollow splittable composite fiber <19>. The intervening D component <21> separates the polymer mutual array <22> A and B components into a large number of parts. That is, as in FIG. 3, it is composed of AB and C (=B), and the C component layer intersects and intervenes so as to divide the AB component layer. The central portion <20> is hollow. These are all divided by the D component, but the D component and the A component or B component may be the same component.

The method and apparatus for obtaining these fibers are described in Japanese Patent Publication No. 49-54707, No. 49-54, for the type shown in Figure 7.
7368, 50−73103, 50−60769, 50−14608, 50−
4320, 50-13620, for the type shown in Figure 8,
It can be obtained by introducing the polymer interlayer array obtained according to the present invention into one of the components of the base mentioned in Japanese Patent Publications No. 51-70366, No. 50-130317, and No. 50-40424. The method can be easily carried out in exactly the same manner as the apparatus and method for obtaining the fibers shown in FIGS. 1, 5, and 6, which will be described later. Once you know these, you will be able to understand how to combine them with the above-mentioned known documents without having to illustrate them one by one. The same holds true for obtaining other types of fiber morphology in combination with the polymeric interarrays of the present invention.

FIG. 9 is a schematic representation to facilitate understanding of the basic apparatus and method of the present invention. The reason why the excellent mutual array of polymers which is the object of the present invention can be easily obtained will be explained in detail below.

Fluid A and fluid B are each guided to the fluid introduction section <23> through the pump. As will be explained later, this can also be said to constitute a fluid introduction section consisting of a part of the fluid alternating array element. Below that, fluid alternating array elements <24> are set in multiple stages. <24> is the first row (displayed as 1t), below it is the second row (displayed as 2t...the same will be displayed in this way up to Nt), and the Nth <25> is displayed.
Display as Nt. These are called the first fluidic alternating element group.

At this time, the AB component fluids are in a pasted state as shown in <39> at the entrance, and then deformed as shown in <40>, taking the simplest pasted state. This is expressed as 2d. Next, <40> is transformed into <
41> and is introduced in a tight fit with the fluid alternating array element <24>. The AB component fluid has a polymer arrangement like <42> in the center of the element,
For the first time, there will be four layers: ABAB. This is displayed as 4d. Similarly, when it is 2t, it becomes 8d, and...
When Nt, it becomes 2×2 to the N power d. The fluid alternating array element thus refers to an element that has the function of sequentially and alternately arranging AB fluids in layers. It is also a type of static fluid mixer. However, since it is meaningless to say that they mix well here, we specifically clarified this as a fluid alternating arrangement element.
An element is a type of basic unit for alternately arranging fluids, and such units are used in series in many stages. A specific example of this fluidic alternating array element will be described later.

In Fig. 9, the drawings are too detailed for 3t, 4t...Nt, so it is difficult to see, so only the direction of the AB fluid interface is indicated by up and down arrows <44> and <45>. <42><43
You can understand this by comparing it with the figure above. <26><32>
is an abbreviation meaning that a large number of such elements were used.

In this way, the first alternately arranged fluid having 2×2 to the Nth power layer (if counted only by A, it is half of that) is arranged relative to the next C fluid, and the second fluid alternately arranged. It is introduced into the array element group together with C fluid. At this time,
What is extremely important is the relationship between the direction of the interface of the layer where the C fluid forms and the direction of the interface of the AB fluid created upstream. It is preferable that the angles Θ formed by these interfaces are substantially orthogonal. In FIG. 9, it is shown to be substantially twisted by an intersection angle of 90±α (0<α<90 degrees). This can be done by twisting the upstream side or the downstream side. It's relative. Furthermore, as will be shown later, a twisting element may be provided to give twist to the fluid.

Note that this should not be confused with static fluid mixers, which often state that each element can be twisted 90 degrees. If each element in the first fluid alternating element group (or in the second fluid alternating element group) is twisted by 90 degrees, not only will the fluid arrangement be disrupted, but it will also be forced to merge with fluid C. Without understanding the meaning of time, that is, the meaning of the arrangement direction of AB fluid and the second arrangement of C fluid at that time, it should never be confused with the change in the orientation of elements in the conventional series arrangement. .

The fluid is then directed to the next fluid alternating array element while converging as smoothly as possible through the rectangular funnel.
Introduce it into the introduction part <29> so that it is in contact with the C fluid. This state is like <48><49>. <
The direction of the AB fluid interface in <48> is essentially twisted by 90 degrees ±α, so it is in the direction of the left and right arrows as in <47>. (In the diagram, it is twisted approximately 90 degrees) <29
If it falls further within >, it will be transformed into <50>. AB
When the fluid is regarded as one fluid, the number of alternately arranged layers is two. This represents 2v. In this case, the number of alternately arranged layers of AB fluid is 2×2 to the N power. In the figure, 2×2
It is expressed as Nth power q. Subsequently, a large number of fluid alternating array elements <30> (denoted as 1'h), . . . <31> (denoted as n'h) are successively provided. These are referred to as the second fluidic alternating array element group.

Thus, at 2'h, there are 4 layers or 4V between the AB and C fluid layers, and the number of AB fluid layers is stretched to 2.
×2 to the (N-1) power, that is, 2×2 to the (N-1) power.
-1) It becomes q. This part is extremely important in understanding the present invention. A specific device will be illustrated and explained in detail later. Furthermore, in n', h,
Between AB fluid layer and C fluid layer, 2×2 to the n power, that is,
2×2 to the nth power v, the number of AB fluid layers is stretched and reduced to 2×2 to the (N−n) power. i.e. 2×2
q to the (N−n) power. Although not shown in detail, <52> indicates such an ABC fluid cross section (see Figure 2). If this fluid is discharged as it is from one die, a fiber or film having such a cross section can be obtained. When taken out from the porous cap, the same number of such items must be included. However, as shown in Fig.
If the particles are distributed smoothly with >, the number of distributed particles will be reduced by the amount divided by that number, but it can still be discharged as a mutual array of polymers. <37> indicates a cap S, which is provided with a discharge hole <38>. At this time, each funnel <35> is inserted as smoothly as possible from the lower part <36> of the fluid alternating array element into the mouthpiece hole <38>.
It is important to arrange the shape so that it leads to If the D fluid is introduced together with the C fluid at this time, the D fluid and the C fluid will form a thin laminate layer. It should be clear that the CD fluid arranges while separating the AB fluid. The above is the first
Although the following explanation has been given on the case where the alternately arranged flow is composed of two fluids A and B, it goes without saying that it may be composed of three or more components. It is clear from the above description that a laminated ABE fluid may be formed in advance by adding E fluid to AB fluid, for example. However, for ease of understanding, the following description will focus on the cases of A and B2 fluids.

The key points of the present invention will be explained in more detail with reference to FIG. <55> in Figure 10 a
indicates AB fluid laminar flow. This can be achieved by arranging a large number of alternating fluid elements in series and introducing AB fluids respectively. This is now shown in a state where it has been introduced so as to have a substantially perpendicular relationship with the C fluid and has merged with it. Figure 10b shows the change when this passes through the first stage of the fluid alternating array element 1'h in Figure 9.
Shown below. In Figure 10a, <56> is C fluid, and <53> is
Indicates the interface between AB fluid layer and C fluid layer, <54>
indicates the interface between the A fluid layer and the B fluid layer. It should be noted that <53> and <54> are substantially orthogonal. In this example, the number of layers of A fluid and B fluid is 8 and 8, respectively. In this example, the one in Figure 10a is first crushed from the horizontal direction so that the vertical direction is doubled, and the thickness of the AB fluid layer increases, and it is in the center, and in the horizontal direction in the figure.
It is divided into two parts and overlapped as shown in FIG. 10b. If we merge the ABC fluids so that their interfaces are parallel, then ABCABCABCABC...
In the present invention, only a known multilayer structure is obtained, which is not the purpose of the present invention. Thus, C fluid layer and C
An AB fluid layer is separated and inserted between the fluid layers. <57> indicates an interface between the C fluid layer and AB fluid layer, and <58> indicates an interface between another C fluid layer and AB fluid layer. <59> and <60> indicate the interface between the A fluid layer and the B fluid layer. <57>
and 〈58〉, 〈59〉 and 〈60〉 are still substantially orthogonal, and the AB fluids have become smaller but their number in the longitudinal direction is reduced, i.e. halved. Attention must be paid to what is happening. From this, in order to obtain A fluid or B fluid with a cross section close to a square (round shape due to interfacial tension), it is necessary to make approximately twice as many divisions between AB fluids upstream as by the C fluid layer. You can probably tell that something is true. Therefore, in order to obtain well-dispersed A fluid or B fluid, it is preferable that the AB fluid be divided at least 1.5 times more than the division after merging with the C fluid. Particularly preferably, it is 1.8 or more. On the other hand, the upper limit is preferably 3 times or less.

Figure 11 shows the same relationship as Figure 10, but the layers <61> and <62> formed by the interface of C fluid.
On the other hand, the case is shown in which the angle Θ formed by the AB fluid interface with the layers <63> and <64> is not orthogonal, nor is it parallel. It will be appreciated that some slope is allowed. In short, the AB fluid interface layer is divided into many parts by the C fluid layer.
At intersection angle Θ=±(90±α)±(integer)×180 degrees,
Preferably, 0<α<45 degrees. Particularly preferred is α<15 degrees.

If a large amount of A fluid is introduced and a reduced amount of B fluid is introduced to form an AB fluid laminar flow, AB
The fluid layer is formed so that the A fluid is thick and the B fluid is thin. If a small amount of fluid C is further introduced and arranged alternately, the result will be as shown in FIG. 12, and a mutual array of polymers with an island height ratio made of fluid A will be obtained. This adds significantly to the economic value when removing the BC fluid and leaving the A fluid. In this sense, it is often preferable that fluid B=fluid C in FIGS. 10, 11, and 12. It will be seen that if the BC fluid layer can be formed without disturbing the A fluid layer, a significantly higher proportion of the A fluid can be produced.

From the above explanation, it is possible to understand how the island component is controlled, a high island ratio is achieved, a super large number of islands is possible, and the interposition of the C component makes it possible to form a polymer mutual array. Probably.

Next, the fluid alternating array element that brings about favorable results in the present invention and why it brings about the effects and configuration shown in FIG. 10 will be explained in more detail.

A fluid alternating arrangement element which provides favorable results for the present invention is disclosed in Japanese Patent Application Laid-Open No. 55-145522 ("Fluid Mixer"). The structure of the present invention will be explained with reference to it, and since the structure of the present invention cannot be understood from the reference alone, supplementary explanation will be added. Its configuration can be restated using the same terminology as that of the present invention: ``At least one unit is provided in which a shape-deforming element having one passage and a moving part having two passages are connected in the conduit.'' It is a fluidic alternating arrangement element of the structure, and the shape deforming part has a shape that is continuous without substantially changing the cross-sectional area of the core passage perpendicular to the extending direction of the conduit while maintaining the cross section of one passage as a parallelogram. The movable part has the same shape at a position adjacent to the shape-deforming part, and the sum of the cross-sectional areas perpendicular to the extending direction of the pipe is equal to the cross-sectional area adjacent to the deformed part. The two passages have two approximately equal passages, and the centers of the two passages are bent without interfering with each other in point-symmetrical positions through the center line of the conduit, and the two passages are bent with respect to each other at both ends of the moving part. Overlapping fluidic alternating array elements (referred to as split-overlap-expansion type fluidic alternating array elements). That is, the fluid is caused to flow in the following manner.

``When arranging the two fluids of polymers A and B in a layered manner by generating an interface within the fluid without causing significant rotation in the laminar flow of the two fluids of polymers A and B, the fluid is divided into at least multiple small parts. Laminar flow formation (split A method particularly preferred for the present invention: ``In this (above) method, the total cross-sectional area of the fluid when the fluid is divided into at least a plurality of small parts, and the overlap There is a method of guiding each fluid so that the total cross-sectional area does not substantially change when the fluids are brought together and recombined.

FIG. 13 is a diagram illustrating a fluid arrangement mechanism of a preferred fluid arrangement element for the present invention.

Now, as shown in FIG. 13a, fluids A and B are supplied to one vertically long rectangular passage <68>. Aisle <68
> has been deformed into a horizontally elongated rectangle as shown in FIG. 13b, but the cross-sectional area of the passage <68> in FIG. 13b remains substantially constant. Figure 13 a to 1
Although the cross-sectional shape of the passage <68> changes continuously in the process of moving to FIG. 3b, the cross-sectional area is configured not to change substantially. A portion where the cross-sectional shape of the passage <68> continuously changes while keeping the cross-sectional area substantially constant is called a shape-deforming portion. Next, one passage <68> is connected to two passages <69>< with the same shape and cross-sectional area via the wall <71>.
Divided into 70> Now let the center of the conduit be M, and let the centers of the individual passages <69><70> divided into two be K and L, respectively. If these relationships are illustrated, the state shown in FIG. 13c is obtained.

Next, the passage <69> is moved above the center K while maintaining the same cross-sectional shape and cross-sectional area, and becomes a passage <69'> whose center is at the position K'. On the other hand, aisle <70
> maintains the same cross-sectional shape and cross-sectional area and moves the center L to L' to form a passage <70'> in Figure 13 d.
The state will be as follows. In this way, from Figure 13c to Figure 13
In the process of transitioning to the state shown in Figure d, two passages <
The centers of 69′><70′> always maintain a point-symmetric relationship with respect to the center M of the conduit. Therefore, the lengths of both passages and the distances between them from the center of the pipe are always the same.

Furthermore, passage <69′> moves to the right to form passage <69″> whose center is at position K″, and while maintaining the above point symmetry, the center L′ of passage <70′> moves to the left. to form a passage <70″> with the center moved to the L″ position. And two passages ＜69′＞＜
70′> results in a state in which the passages <68> are stacked in a direction parallel to the cutting line cut by the wall <71>. This state is illustrated in Figure 13e.
It is. FIG. 13f shows the state in which the fluids exiting the passages <69'><70'> are stacked (overlapping) and reach the next passage <68>. Figure 13 e~
Since the fluid only changes position at f, the part that performs this action is called a moving part. Figure 14 shows the state from Figure 13 a to 13
It is a figure explaining the structure of the process of transforming into the state of FIG. b.

FIG. 14a shows one aspect of the cross-sectional change during the transition from the passage in the state of FIG. 13a (solid line) to the passage in the state of FIG. 13b (dotted line). now,
The passage cross-sectional shape shown by the solid line is shown by the rectangle OPQR,
The cross-sectional shapes indicated by dotted lines are each indicated by a rectangle O′P′Q′R′. Now, the corresponding points OO′, PP′, QQ′,
When RR′ changes in a straight line, and the cross-sectional shape in the middle is a quadrilateral inscribed in this group of straight lines, with sides op, pq, qr, and ro parallel to OP, PQ, QR, and RO, respectively, then takes the maximum value when the quadrilateral opqr becomes a square, and is larger than the area of the rectangle OPQR.
It becomes 1.125 times. This degree of change in cross-sectional area is the mixer (fluid alternating array element) shown in Japanese Patent Publication No. 39-437.
It is extremely small compared to twice that of , and can be seen as virtually unchanged, and the device is easy to manufacture. If you want to obtain a more precise device, the 14th
As shown in figure b, the lines OO′, PP′, QQ′, and
If RR′ is a right-angled hyperbola with a convex shape inside, it is possible to create a passageway with no change in cross-sectional area.

Furthermore, by arbitrarily selecting a curve connecting OO′, PP′, QQ′, and RR′, the cross-sectional area can be changed to take a minimum value or a maximum value.

In the fluid alternating arrangement element suitable for the present invention, the entrance/exit of the passage <68> (the cross-sectional shape in FIGS. 13a and b has a rectangular side length;
and <70′><70″> are best square. This will result in a device with the smallest cross-sectional area, but in the use of the present invention,
It is not limited to this.

FIG. 15 shows an example of one unit of fluid alternating array element that can be suitably used in the present invention.
Figure a is a front view, Figure 15 b is a side view, Figure 15 c
1 and 2 respectively show plan views. In actual use, a number of these units are connected in series. However, in order to conveniently introduce and discharge fluid, it is often convenient to use a unit with a shape cut at a specific part and connect it to the lower and upper parts of the unit, respectively. It can be used for the introduction part and discharge part of fluid A and fluid B in Figure 9, and the introduction part and discharge part of fluid C and AB fluid.)

It may be introduced in any of the G, H-H, I-I, and J-J cross sections, but it is recommended to
You can decide as appropriate by looking at Figure 6g.

The correspondence between FIG. 16 and FIG. 13 is as follows. 13a and 16c, 13b and 16e, 13c and 16f, 13d and 16g, 16a and 13e. and FIG. 16b, and FIG. 13f and FIG. 16e correspond, respectively.

What should be noted here is Fig. 16 a, b, c.
These are the left and right arrows. This indicates that the two fluids are stretched and flattened along with the interface in the order of a, b, and c in the direction formed by the fluid interface. At this time, note that if the two marks are at the tip of the arrow, the distance between them is increasing. This is useful for understanding the situation when the AB fluid and the C fluid are arranged alternately as shown in FIG. 10.

FIG. 17 is a perspective view showing an example in which one unit of the fluid alternating array element that can be suitably used in the present invention is composed of two divided members. In FIG. 17, one unit of the fluidic alternating array element can be composed of two members a and b. U, V, W of these two members a,
When X is combined with points u', v', w', and x' of member b, it becomes 1
two units are formed.

In Fig. 17a, 75, 75'75''...75''''' are located at the uppermost position, and in Fig. 17b, 76, 76', 76''...76''''' protrudes upward.

If these members a and b are arranged in a rectangular tube having a hole with a square cross section, it can be easily assembled and disassembled for cleaning.

Such an alternating fluid array element is a type of generally-called static fluid mixer, and since the word "mixing" is not quite the same as the word "array", it is more correctly called an alternating fluid array element here. It is known that mixers can be classified into two types: (1) relative position movement of multiple passage pipes, and (2) relative position movement due to flow velocity distribution occurring in the cross section of the passage pipes. Although the latter cannot be used in the present invention, the former is far more suitable for use in the present invention. Fluidic alternating elements that are inferior to the previously described fluidic alternating elements, but which are next in line with the principles of the present invention, include the following: Dutch patent no.

There is −437.

In Japanese Patent Publication No. 39-437, if the terminology is unified as much as possible in the present specification and replaced, it is stated that ``An interface is created in the fluid without causing significant rotation in the laminar flow of two polymer fluids A and B. In order to arrange the two fluids of polymers A and B in a layered manner, the fluids are divided by cutting the interface, then the interface of each divided fluid is expanded, and then they are overlapped and rejoined (divided-expanded-overlap method). ``A method of causing a laminar flow of two polymer fluids A and B to generate an interface within the fluid without causing significant rotation.''
When arranging two polymeric fluids in a layered manner, the fluids are divided by cutting the interface, then overlapped and recombined, and the device element that expands the interface of the combined fluids (division-expansion-overlap type fluid alternating arrangement element) ) has been disclosed. This involves expansion and contraction of the fluid flow path for each array, so the array is compared to the above-mentioned elements.
Although it is inferior because it tends to be easily disturbed, it can be applied to the present invention.

Furthermore, in Japanese Patent Application Laid-open No. 48-94945, the liquid flow was
An alternating array fluidic element is disclosed which comprises a unit consisting of a dividing plate and a guide plate through which the divided liquid flows alternately at 45 degrees in the longitudinal direction. This fluidic alternating array element is also applicable to the present invention. In addition, Sakura Seisakusho Co., Ltd.'s ``Sukiur Mixer'' is known in this type of industry, but you only need to pay attention to the fact that the fluid is arranged diagonally and alternately, and Sulzer Co., Ltd. (Switzerland).
Examples include static mixing element SMV type.

After knowing the present invention, it will be easy to see what fluidic interleaving elements can and cannot be applied.

FIG. 18 is an example of a discharging device for polymer mutual arrays according to the present invention. Since the length of this device is long, a and b are drawn in two parts, but it is necessary to overlap S and S' in a and S and S' in b and view the diagram as a whole. .

The same applies to other blocks.

This packing section can be maintained by pressing against three fluid supply holes provided in the spinning head. Each of the fluidic alternating array elements has already been described in detail, so although they are not drawn in detail, they will be obvious without needing to be described in detail.

FIG. 19 is a perspective view for easy understanding of the state in which the insert block <97> is housed in the pack outer cylinder.

<97> has a protrusion <97'>, and the aforementioned polymer introduction holes <101>, <103>, and <105> are present. It will be easier to understand if the MM' cross section of the pack outer cylinder is shown in FIG.

In general, a round shape is preferred for the fluidic alternating array element.
This is because the round shape makes it easier to make holes with a lathe or drill. The square hole provided in the insert block of the present invention can be made by drilling a small hole and cutting it into a square shape, but first, divide the insert block into two parts, make a square groove, and then There is a clever method of aligning them, fastening them deeply with screws, then cutting and machining the outer shape to match the inner dimensions of the pack's outer cylinder, hardening it, or making it independently and securing it with screws.

Next, various aspects of how to arrange the first fluid alternating element group and the second fluid alternating element group will be described.

FIG. 20a shows the first fluidic alternate arrangement element group <111>
This is a method of arranging a second fluidic alternating array element group <112> in series.

Fig. 20b shows that when the method of a is too vertically long, the first fluidic alternate arrangement element group <113> is arranged in a rising shape from the bottom to the top, and the second
It is introduced together with C fluid into the fluid alternate array element group <114>.

Fig. 20c shows that even with method b, if the length is too long, the first fluidic alternate arrangement element group is set to <115> and <116>.
Divided into two parts, <115> is placed vertically, and <116>
are arranged in a rising form from bottom to top, and C is placed in the second fluid alternating array element group <117> so as not to disturb it.
It is introduced together with the fluid. Although I have explained it using the expression "top and bottom," it is the same even if you read it as "left and right." In these cases, between <111> and <112>, <113>
For example, between <114> and <116> and <117>,
Needless to say, a twist of 90 degrees is necessary.

FIG. 21 shows the first fluid alternating array element <118>...
This figure shows a preferred embodiment in which a plurality of second fluidic alternating element groups <123> are provided for one group of <120>;<119> is an abbreviation as before.

The AB fluid alternating array is passed from <121> through the branch conduit <122> tube in a 90 degree twist to the C
Together with the fluid, it is guided to the second fluid alternating array element group <123>. As a result, the C fluid intersects in layers so as to divide the interface between the layers in which the AB2 fluids are alternately arranged. It must be noted that the group of branch conduits <122> has the effect of further dividing the AB fluid and in that direction.

FIG. 22a shows an example of the structure and method of such fluid branching, and the direction of the AB fluid layer is indicated by left and right arrows <124>. It is divided into several parts (5 parts in the figure) in a direction perpendicular to the direction of this arrow. It must be noted here that it is not divided into several parts parallel to the double arrows. In this way, for <120> in Figure 21, <121>
<125> can be followed in the same way as <125> is followed. Thus, the AB fluid alternation can be divided into <126> each to form the next alternation with C fluid.

On the other hand, Fig. 22b shows the direction of the fluid layer of the AB fluid with the double arrow <
This is a duct that has an enlarged flow path that can stretch the AB fluid in the layer direction by allowing the <127> to flow into the <128>.

The fluid conduits <128> to <130> are enlarged, and the fluid <130> is expanded through each conduit <131>...<131n′>.
＞<131′>……n pieces up to <130n′> (20 in the figure)
(depicted separately) and subjected to subsequent mutual distribution with C fluid. (In the figure, <132>, <132'>
...Distributed into <132n′> and piped alternately in a circular pattern. ) In this way, distribution efficiency can be significantly increased. However, in the present invention, higher efficiency can be achieved by increasing the number of fluid alternate array elements by a space corresponding to <128><129><130>. There are many things you can do.

The secret to effectively achieving the present invention is to avoid creating dead spaces in the fluid flow, to avoid repeated expansion and contraction of the fluid, to avoid sudden expansion and contraction of the fluid, to avoid sudden changes in the direction of the flow, and to avoid fluid flow. The absolute dimensions of the flow (of the layer) should be kept as small as possible, other than converging smoothly and gently into a funnel just before the outlet hole, and the residence time should be minimized. things to do, etc.

In particular, the fluid should not be squeezed too finely in the upstream.
It is preferable to narrow down to 1/15 or less just before the discharge hole.

Figures 5, 6, and 7 show the flow of polymer mutual arrays.
As shown in Figure 8, surrounding it with another component,
If you want to make a sea-island composite fiber with one more component, you will need one more component, making a total of four components.
Obviously this is also possible. However, in many cases, such a component is not necessary for the fiber, and a cap holder (pack) that can withstand such a component, a pump, its drive unit, and circuit are not required, making it uneconomical. In such a case, when one wants to add another component to the one shown in FIG. 20a, it is often desired to make the C component common to the B component.

FIG. 23 shows a preferable method when, in the case of FIG. 20a, the C fluid is equal to the B fluid, and the C fluid is desired to be one component of the polymer mutual array complex of the AB fluid. That is, when the B fluid is distributed and used as one fluid of the alternating array body flow with the AB flow, B is divided into two parts, and before reaching the fluid alternating array element, the resistance part T,
This indicates that it is preferable to provide T'. <
134><135> with an adjustable resistance (e.g.
Fluid B can be successfully delivered to each desired amount by adjusting it with a screw or by installing a small tube and adjusting it little by little through trial and error until the desired value is reached. Note that <133> is a first fluid alternate array element group, and <136> is a second fluid alternate array element group. Thus C can be used as a third component.

In Fig. 24, B fluid is used in the same way as Fig. 20b.
When dividing, resistor T at <137> and resistor at <138>
If the B fluid is to be divided into two in the same manner as in FIG. 25 and FIG. Even if it can be temporarily distributed successfully without resistance,
Difficult to distribute uniformly for a long time. In addition, <139><143><
144> is the first fluid alternating array element group, <140><145>
is the second fluidic alternating array element group. Fluid C can be used in the same manner as described above.

It is clear from the example of FIG. 18 that all of FIGS. 20 to 25 can be accommodated in the insert block.

Furthermore, Fig. 26 is based on the method of Fig. 23 and Fig. 18.
C with a core of polymer mutual array consisting of AB fluid
A configuration for obtaining fibers as shown in FIG. 5 using a fluid as a sheath,
Shows how. A polymeric mutual array consisting of AB fluid is introduced in <146>. The fluidic interleaving element is disposed thereon in the insert block <147>. The flow of polymeric interarrays directed to <146> is distributed through the guide holes <148>. On the other hand, the polymer C fluid is introduced from the guide hole <149> in a manner similar to that shown in FIG. 18 but with a different distribution. The method for making this change is easy and obvious without needing to be described in detail. These are provided in the insert block <150> which has these holes.

Polymer mutual array flow is the first upper cap plate <151>
A protrusion with a hole <153> provided on the second cap plate <152> that is guided through the hole provided with and provided below the second cap plate <152>
is fitted and protrudes downward. This has a hole <154>, which is followed by a guiding hole <148>. This protrusion is held down by the upper plate <151> to prevent it from slipping upward from <152>. This protrusion <153> is pushed into the recess provided in the lower base plate <155> while maintaining a small gap. Further, a discharge hole <158> is provided at the bottom of the depression.

The polymer C fluid is introduced from <149> into the middle between the base plates <152> and <154>, and is introduced into the depressions and protrusions <153>.
It is discharged from <158>, passing through a narrow gap between the polymers and surrounding the polymer interlayer array stream. These cap plates are fixed with screws <156><157>, etc.

Needless to say, many such core-sheath components are also placed in other parts of the cap.

FIG. 27 shows the structure and method for producing a sea-island composite fiber made of mutually arranged polymers. It is very similar to Fig. 26, but the cap is different. Polymer mutual arrays are <146′> and <
148′> and reaches the upper cap plate <159>. This has a small hole group <165>, passes through the middle cap <160><162>, then the lower cap <163>,
It reaches the discharge collecting nozzle <164> and is discharged from the discharge hole <169>. A pipe <166> is embedded in the middle mouthpiece, and is held in place by <160> and <159> to prevent it from being pulled out. This pipe <166> has a cap plate <
It passes through the space for introducing C fluid between <162> and <163> and is inserted into the hole provided in the base plate <163>. The hole <167> provided in the cap plate <163> is larger than the pipe, forming a narrow annular space. Therefore, a core-sheath flow directed to one pipe is formed, and at the same time, a large number of core-sheath flows are collected in a funnel-shaped collection part <168>,
Smoothly narrowed and converged, as a sea-island style <169>
It is discharged from. Needless to say <
146'>, a first fluid alternating element group and a second fluid alternating element group are provided, and
The system and structure shown in FIG. 23 are used for fluid distribution. Also, C fluid is introduced into <149>, and <170>
<161> is a bolt for fixing the cap plates to each other.

Such units are also provided elsewhere on the base plate. In the diagram, the number of pipes is 3, but 1
There are 16 pipes per unit (collection part <168>), which in this case is 16 islands.

For example, the number of islands is 3.4, 5, 7, 8, 11, 12, 13,
15, 16, 24, 36, 60, 70, 145, 223, etc. can be selected as appropriate. The island component (AB) ratio can be more than 50% of the total, and can sometimes be around 90%.
With this method, it is possible to form bundles of fibers, even with fiber denier on the order of 100 microdenier.
Even the 1000 microdenier order is easily obtained.

How to spin other bonded composite fibers and split composite fibers based on the above explanation?
It should be clear enough. It is also clear from Figures 18, 26, and 27 that both the ABCD four-component device and the four-component fiber can be easily produced.

Now, in FIG. 9, the second fluid alternating array element group is substantially twisted by about 90 degrees relative to the first fluid alternate array element group ((90 degrees ± 45 degrees) ±
(integer) x 180 degrees), but these element groups may be left as they are and only the torsion element inserted as a connecting pipe may be used. An example of such a torsion element is shown below.

Figure 28 shows a rectangular tube twisted 90 degrees. When entering through the entrance of <171> and exiting through <172>, it is twisted 90 degrees. If the fluid has strong viscoelasticity, it may be twisted a little further. Each part of a and b in <171> is <172
>, the fluid comes out through twisting at a' and b'.

Figure 29 shows a torsion element with a rectangular outer shape, where the hole <173> becomes <174> and <171><172>.
As in the case of , it is twisted internally. Therefore, parts c and d come out at c' and d'.

FIG. 30 shows a torsion element having a cylindrical outer shape, and the degree of twist between <175> and <176> is the same as in FIG. 28. e is twisted into e' and f is twisted into f'.

Figure 31 shows a torsion element which is cylindrical both inside and outside, with a torsion plate <180> inserted inside, <177> being <177'> and <178> being <
178′>. However, since the torsion elements are more likely to cause fluid turbulence than the respective fluid alternating elements, it is preferable to avoid using them as much as possible.

Now, as a preferable polymer, A/B, A/B/C, (including B=C) Examples of each fluid are shown.

PET = polyethylene terephthalate or its modified products (including various known copolymers), N = nylon (66, 6, etc.), PE = polyethylene, PST
= polystyrene, PBT = polybutylene terephthalate, PEG = polyethylene glycol, a PET/5-sodium sulfoisophthalate copolymer PET b N/5-sodium sulfoisophthalate copolymer PET c PET/PST d PET /2-ethylhexyl acrylate copolymerization PST e N/2-ethylhexyl acrylate copolymerization

Thus, the present invention has achieved all of the objectives of the present invention without mentioning them one by one. Its application is extremely wide and is used in many of the applications already mentioned. This enables extremely useful applications in industry.

As mentioned above, the configuration and method of the present invention have been specifically explained in detail. Next, Examples according to the present invention will be shown, but the effectiveness of the present invention is not limited by these in any way, but rather they bring about the following application development.

Example 1 Using a three-component spinning machine, the first
A large number of fluid alternating array elements shown in Figures 5 and 16 are arranged, polyethylene terephthalate is arranged as the island component A, and polystyrene is used as the sea components B and C.
Spun at 285 degrees Celsius. At this time, the number of first fluid alternating array elements is 16, the number of second fluid alternate array elements is 8,
The intersection angle between AB fluid and C fluid was approximately 90 degrees. Furthermore, although the fluid is in a normal type mouthpiece, the discharge hole and the funnel-shaped expansion just above it are 15
The yarn was spun from the doubled spindle. The number was 6 holes. At that time, the distribution number is A among AB fluids.
Focusing only on the fluid, the number of islands of A per hole on average is (2 to the 8th power) x (2 to the 8th power)/6 = approximately 1092, and the polymer interlayer array fiber has approximately 1000 islands. It was done.

At this time, the fiber contained 60 parts of the A component, 20 parts of the B component, and 60 parts of the C (=B) component, and was drawn with 2.8 times steam to form a polymer interlayer array fiber of about 3 denier. When calculating the denier of the remaining ultrafine fibers from the polymer interlayer array fibers after polystyrene was dissolved and removed with trichlorethylene, it was found to be 3 x (60/100) x (1/1092) = about 0.0015 denier on average.

Example 2 As in Example 1, 55 parts of polyethylene terephthalate, 15 parts of B component, and 15 parts of B' component were used as the island component A in a polymer mutual arrangement, that is, for the above subtotal of 85 parts,
C component (sea component) 15 parts, first fluid alternating array element
18. Spinning was carried out at 285 degrees C using a three-component composite spinning machine with 9 second fluid alternating array elements (27 in total), 16 islands, 18 sea-island fiber outlet holes, and 18 holes. The spinning condition was good. The number of islands at this time was 16 islands/fiber, and the denier of the obtained polymer mutual array fiber after drawing was
It was 2.5d. When examined with an electron microscope, the A component was very well dispersed and very fine, so the degree of dispersion was determined by calculation. The results are as follows.

The number of distributed A per fiber, that is, approximately (2 to the 9th power x (2 to the 9th power)/18 = 145631 The number of distributed A per island, that is, (2 to the 9th power) x (2 to the 9th power) )/18/16 = approx. 910, denier of ultrafine fiber, 2.5 x (55/100) x (1/14563) = approx. 0.000094 = 94 microdenier (average) Polystyrene is removed from this single fiber with trichlorethylene It was found that the fibers were made up of 16 bundles of about 900 94 microdenier ultra-fine fibers.
