BACKGROUND OF THE INVENTION
The present invention relates to a papermaking fabric, and more particularly to a papermaking fabric.
[0002]
[Prior art]
The papermaking method is a well-known technique. First, a papermaking raw material containing pulp fibers and the like is formed endlessly from a head box, placed between rolls of a papermaking machine, and supplied onto a running papermaking fabric.
The side on which the raw material for the papermaking fabric is supplied is the papermaking surface, and the opposite side is the running surface.
The supplied raw material moves as the papermaking fabric travels, and during the movement, moisture is removed by a dewatering device such as a suction box or foil installed on the traveling surface side of the fabric to form wet paper. That is, the papermaking fabric functions as a filter and separates pulp fibers and water.
The wet paper formed in this papermaking zone is then transferred to the press zone and the dryer zone.
In the press zone, the wet paper is transported by a papermaking felt, and is squeezed by a nip pressure between the press rolls together with the papermaking felt to further remove moisture. In the dryer zone, the wet paper is transported by a papermaking canvas and dried to produce paper.
Papermaking fabrics are woven with a loom using warps and wefts such as synthetic resin monofilaments. In order to form it endlessly, it is formed endlessly by a known weaving joint, pin seam or the like, or endlessly formed by a bag weaving machine at the stage of weaving.
In the case of bag weaving, the relationship between warp and weft is reversed on the loom and in use.
[0003]
In this specification, the warp is a yarn extending in the machine direction of the papermaking machine, that is, the direction of movement of the fabric when in use, and the weft is a yarn extending in the cross machine direction of the papermaking machine, that is, in the width direction of the fabric. is there.
There are more demands than ever for papermaking fabrics, especially papermaking fabrics.
These include improved surface smoothness, prevention of paper wire mark generation, improved papermaking yield, good drainage, wear resistance, dimensional stability, and running stability.
In recent years, with the increase in papermaking speed, the increase in neutral papermaking, the increase in the amount of filler used, and the paper company's cost reduction policy, an early solution to the above demand is strongly desired.
When the papermaking speed is increased, the dehydration speed is inevitably increased and the dehydration power is increased. Since the papermaking raw material is dehydrated through the papermaking fabric, moisture is removed through the mesh formed between the yarns of the papermaking fabric. This is the water space. However, since not only moisture but also fine fibers and fillers are removed together from the papermaking raw material, the retention (papermaking yield) decreases. Also, the wet paper that remains on the fabric is pressed against the surface of the paper by the dehydration force, so the yarn is difficult to wet in the part where the yarn is present, and conversely between the meshes where the yarn is not present The wet paper is difficult to get between the meshes, and threads and mesh marks are generated on the wet paper surface.
Further, since fibers are more retained between the meshes, the fiber density becomes excessively dense, the density of the fiber density of the paper is also generated, and the paper is thick and thin.
This is called a wire mark or drainage mark.
In addition, when the wet paper bite becomes large or the fiber bite occurs, there arises a problem that the wet paper peelability from the papermaking fabric is deteriorated when the wet paper is transferred to the felt. Although it is impossible to completely eliminate the wire mark, in order to make it as small and inconspicuous as possible, the paper surface of the woven fabric must be made fine to improve the fiber support and smoothness.
When the dewatering speed becomes high and the dewatering power becomes strong, naturally, the occurrence of fiber detachment and the generation of wire marks become remarkable, and therefore the performance of the papermaking fabric needs to be further improved.
Further, since the fibers are oriented in the running direction of the fabric, it is particularly necessary to improve the fiber support of the weft yarn.
Also, excellent drainage is required for good dehydration under high-speed conditions. If it has excellent freeness, the vacuum pressure of dehydration can be suppressed, and the above-mentioned fibers are not trapped or pulled out, the occurrence of wire marks can be eliminated, and the retention can be improved. .
Also, when the papermaking speed is increased, water contained in the fabric is scattered by the roll rotating part, etc., and splashes occur, and the water drops fall on the wet paper and generate marks, so the water retention of the fabric is reduced. Is also required.
In recent years, twin wire type paper machines such as hybrid formers and gap formers have increased rapidly, and this problem has become one of the most important issues to be solved.
[0004]
On the other hand, the increase in neutral papermaking made the demand for improved wear resistance even stronger. Neutral papermaking uses calcium carbonate as a filler and, unlike acidic papermaking, causes severe wear on the yarn on the running surface. In addition, the speed of papermaking and the excessive dehydration accompanying the decrease in drainage due to the fiber yield make the conditions more severe.
In order to improve the wear resistance, measures are taken such as changing the fabric structure to a weft-worn type structure or changing the material of the thread.
In general, from the standpoint of improving the wear resistance and maintaining the posture stability of the woven fabric in use, it is preferable to give the weft yarn of the woven fabric a wear resistance action. As a matter of course, when the warp is worn, the tensile strength is lowered, the dimension of the fabric is increased, and when the warp is worn and cut by wear, the fabric itself is cut and the service life is exhausted.
Attempts have also been made to use polyamide monofilaments with excellent abrasion resistance for wefts, but this attempt does not improve the structure of the fabric itself, but merely uses the properties of the materials used. Thus, the epoch-making effect cannot be obtained, and the fabric using the half-faced polyamide monofilament has a drawback that the posture stability is poor.
Attempts have also been made to use thicker yarns for the wefts on the running surface, but this has problems such as the fact that the balance between the warp and the weft is lost, the crimpability is deteriorated and the wire mark is generated, and there is a problem in practice. It was.
[0005]
In order to prevent the occurrence of paper wire marks, it is conceivable to increase the number density of warps and wefts and improve the support of the fibers. To that end, it is necessary to reduce the diameters of the warps and wefts.
However, in a well-known warp / single weft / double woven fabric generally used at present, the wear resistance, rigidity, and posture stability are reduced when the wire diameter is reduced.
In this way, the papermaking fabric loses surface properties when the wire diameter is increased in order to improve wear resistance and rigidity, wire marks are generated on the paper, and conversely the wire diameter is increased in order to improve surface properties. When the number density is increased by thinning, the wear resistance and rigidity are lowered, so to speak, there are conflicting problems.
[0006]
In order to solve the above-mentioned problems, an attempt has been made with a woven fabric in which the papermaking surface side and the traveling surface side are configured using separate warp and weft yarns, and the fabrics of both layers are integrated by binding yarns. Yes. In other words, a warp and weft with a small wire diameter are used for the fabric on the paper surface side to form a dense paper making surface, and a warp and weft with a large wire diameter are used for the fabric on the running surface side for running with high wear resistance. A surface is formed.
However, this was not always satisfactory. This is because, in the binding portion where the binding yarn intersects with the yarn on the paper surface side, the binding yarn pulls the paper surface side fabric toward the running surface side, so that a dent is generated on the paper surface side fabric surface, and the paper actually When the paper is drawn, the dent mark is transferred to the paper and a wire mark is generated.
Also, in order to reduce this dent as much as possible, if the wire diameter of the binding yarn is reduced or the number of binding yarns is reduced, the binding yarn becomes weak. Internal wear occurs between the woven fabrics, and the bonding force is further weakened, resulting in a problem that a gap is generated between the paper surface side fabric and the running surface side fabric or the service life is exhausted. Moreover, since it is a two-layer fabric, the thickness of the papermaking fabric is also increased, and there is a problem that the water retention described above is increased.
[0007]
By the way, in order to effectively improve the support of the fiber and to produce a good quality paper without generating a wire mark on the paper, it is necessary to support the fiber with a weft. This is because the pulp fibers generally supplied from the head box onto the papermaking fabric are oriented in the machine direction, that is, the warp direction. By supporting the fibers by dividing the recesses between the warps with wefts, the fibers are prevented from staying between the warps.
Therefore, in order to solve the above-mentioned problems, single-layer fabrics for papermaking in which auxiliary wefts are arranged on a single-layer fabric of a weft wear type are disclosed in JP-A-2-68383, JP-A-2-68384, and JP-A-2-68385. JP-A-3-279485 proposes. Because it is a single-layer fabric, its thickness is small and its water retention is small, and since the fabric body is a weft-wear type, it has good wear resistance. Auxiliary wefts are arranged to fill in the dents formed in the fabric body. Smoothness and fiber support of the weft can be improved, the above-mentioned purpose has been achieved, and a certain level of effect has been proved. However, the weft of the auxiliary weft is small and the retention is not sufficient, so a high pressure shower is applied. In some cases, the auxiliary weft thread vibrates and fibrillates.
In addition, because the weft of the auxiliary weft is small, the bent shape of the auxiliary weft is not firmly formed, and the meshing between the auxiliary weft and the warp is bad during the weaving operation to form the woven fabric endlessly. There was also a problem that unevenness occurred at the joint and the smoothness was impaired.
[0008]
[Problems to be solved by the invention]
In view of the above-mentioned problems, the present invention has a low water retention, wear resistance, surface smoothness, good weft fiber support, strong weaving of auxiliary wefts, and no movement of auxiliary wefts. It is intended to provide a fabric.

[0010]
DETAILED DESCRIPTION OF THE INVENTION
A feature of the present invention is that a long crimp is formed on the paper-making surface side through the upper side of a plurality of wefts in which the warp is continuous, and a long crimp is formed on the running surface side in the lower side of the plurality of warps in which the wefts are continuous. A weft-wearing type single-layer woven fabric is formed, and auxiliary wefts are arranged between the wefts of the main body of the fabric, and before and after the position where the warp weaves the wefts from below, the auxiliary wefts adjacent to the wefts from above This is a configuration that weaves.
Because it is a single-layer fabric, the thickness of the fabric can be reduced to reduce water retention, and water contained in the fabric is scattered by the roll rotating part, etc. even when the paper machine speed increases, and the water droplets become wet. There is no problem of falling on paper and generating marks.
In addition, the use of the weft wear type provides a structure in which the weft protects the wear of the warp and the wear resistance is improved.
Further, by arranging the auxiliary wefts between the wefts, the fiber supportability and surface smoothness of the wefts are improved, and the generation of wire marks and the retention of pulp fibers between warp yarns are prevented. The auxiliary weft is preferably arranged between all the wefts in view of surface uniformity.
The auxiliary weft is structured so that the warp weaves from the upper side before and after the position where the weft is woven from the lower side, so that the auxiliary weft is strongly woven into the structure, and the auxiliary weft can be retained without moving. It is good and the bend shape is firmly formed.
[0011]
The position where the warp weaves the weft from the lower side is the position where the warp is located below the weft, the part where the warp is located at the lowest position. The warp yarns are located at the lowermost position and when the warp yarns are woven from the upper side to the upper side of the weft yarns.
Since it is woven at that position, the auxiliary weft can be pulled deeply and deeply woven into the structure.
In addition, when weaving back and forth, the result is that the auxiliary weft is woven twice in the complete structure, which increases the number of places to weave, which also increases the retention of the auxiliary weft.
Furthermore, the surface smoothness can be further improved by arranging the auxiliary wefts on the upper side of the warp yarns at portions other than the position where the front and back auxiliary wefts are woven from the upper side of the position where the warp weaves the weft yarns from the lower side.
[0012]
The yarn forming the woven fabric does not bend at a right angle at the intersection between the warp and the weft, and the crimp is not formed in a rectangular shape, but is usually bent in a curved shape at the intersection, so that the crimp is formed in an arcuate shape.
For example, a warp crimp formed on the paper surface side is formed by projecting to the paper surface side in a bow shape between a position where wefts are woven from below and a position where wefts are woven next from the bottom. The center part protrudes most to the papermaking surface side. Accordingly, a difference in height is generated on the papermaking surface, and a dent is generated, and the surface smoothness is impaired.
The conventional single-layer fabric for papermaking in which the above-mentioned auxiliary wefts are arranged is based on the idea that the auxiliary wefts are arranged in the recesses to improve the surface smoothness, but there are problems as described above.
[0013]
In the present invention, unlike the conventional idea of filling the dent, the surface smoothness is improved by reducing the height difference by bringing the bow shape of the crimp of the warp closer to a straight line.
That is, before and after the position where the warp weaves the weft from the lower side, the auxiliary weft is in the middle of the warp going down from the upper side of the weft to the lower side of the weft and in the middle of the warp going from the lower side of the weft to the upper side of the weft. In the part of the weft arranged below the warp, the auxiliary weft pushes the warp upward and the other weft is located above the weft to form a crimp on the paper side. Since the auxiliary weft pushes down the warp downward in the part arranged on the upper side of the warp, the warp bends at a right angle in the part where the warp weaves the auxiliary weft, and in the crimp part of the warp the crimp shape is linear from the bow shape As a result, the paper surface becomes smooth. This will be described in detail later with reference to the drawings.
[0014]
Further, since the warp is formed in a straight line, the elongation rigidity in the warp direction is improved. The yarn used in the present invention can be freely selected depending on the properties desired for the papermaking fabric and is not particularly limited.
For example, in addition to monofilament, multifilament, spun yarn, crimped or sublime processed textured yarn, bulky yarn, processed yarn called stretch yarn, molding yarn, or these are combined. Can be used. Further, the cross-sectional shape of the yarn is not limited to a circular shape, and a square shape, a star-shaped rectangular shape, a flat shape, an elliptical shape, a hollow shape, and the like can be used.
The material of the yarn can be freely selected, and polyester, nylon, polyphenylene sulfide, polyvinylidene fluoride, polypropylene, aramid, polyetheretherketone, polyethylene terephthalate, cotton, wool, metal, and the like can be used.
Of course, you may use the thread | yarn which blended or contained various substances according to the objective to these copolymers or these materials.
[0015]
In general, it is preferable to use polyester monofilament that is rigid and excellent in dimensional stability for the paper surface side warp, running surface side warp, and paper surface side weft, and has a small wire diameter and shower resistance and fibril resistance. Nylon monofilaments are preferably used for auxiliary wefts that require a high degree of conversion.
In addition, it is preferable to interweave polyester monofilaments and nylon monofilaments on the running surface side wefts that require abrasion resistance, such as by alternately arranging polyester monofilaments and nylon monofilaments in order to improve wear resistance while ensuring rigidity.
In addition, it is also possible to arrange a plurality of yarns in the same structure where the yarn is originally one yarn. By arranging the fine wire diameter yarns together, it is possible to improve the surface properties and reduce the thickness of the fabric.

In the drawing, the warp is indicated by Arabic numerals, for example 1, 2, 3; the weft is indicated by dashes, for example 1 ′, 2 ′, 3 ′; the auxiliary weft is indicated by double dashes. For example, 1 ″, 2 ″, 3 ″.
Further, the x mark indicates the position where the warp is located above the weft and auxiliary weft, and the white square indicates the position where the warp is located below the weft and auxiliary weft.
[0017]
FIG. 1 is a design diagram showing the complete structure of Example 1 of the present invention.
In the design diagram of FIG. 1, 1, 2, 3, 4, 5 are warps, 1 ', 3', 5 ', 7', 9 'are wefts, 2 ", 4", 6 ", 8", 10 " ″ Is an auxiliary weft.
The fabric excluding the auxiliary wefts of this embodiment, that is, the main fabric of this embodiment is a 5 shaft 4/1 satin weave fabric.
This is because, when only the main fabric is removed except for the auxiliary weft, the warp 1 passes over the lower side of the weft 1 'and then continues on the upper side of the four wefts 3', 5 ', 7', 9 '. A long crimp is formed on the paper-making surface, and the warp yarns 1 are sequentially shifted by two weft yarns so that the warp yarns 2, 3, 4, and 5 are arranged to form a complete structure. . Next, looking at the auxiliary wefts, it can be understood that the auxiliary wefts are arranged between the respective wefts.
Since the auxiliary weft is arranged, the fiber support in the weft direction is good.
In this embodiment, auxiliary wefts are arranged between all the wefts. However, the present invention is not limited to this. For example, the auxiliary wefts can be arranged every one interval.
And it can be understood that the auxiliary wefts are woven from the upper side before and after the position where the wefts are woven from the lower side by the warp.
For example, the warp 1 weaves the weft 1 'from the lower side, and weaves the full-structure auxiliary weft 10 "and the auxiliary weft 2" following the lower side located before and after the weft 1' from the upper side. It can also be seen that the auxiliary weft is a complete structure and is woven from the upper side at two locations by warp. For example, the auxiliary weft 2 ″ is woven from the upper side by the warp 1 and the warp 4. In this embodiment, all the portions other than the position where the auxiliary weft is woven from the upper side by the warp at the above position are above the warp. Has been placed.
For example, the auxiliary weft 2 ″ is woven from the upper side by the warp 1 and the warp 4, but is arranged on the upper side at the intersection of the other warps 2, 3, 5.
As for the warp 1, the auxiliary wefts 4 ″, 6 ″, and 8 ″ other than the auxiliary weft 10 ″ and the auxiliary weft 2 ″ woven from the upper side of the warp 1 are arranged on the upper side of the warp 1.
The above configuration is well understood from FIG. 6 which is a cross-sectional view along the warp 1.
The auxiliary wefts 10 "and 2" push the warp 1 upward, and the auxiliary wefts 4 ", 6" and 8 "push the warp 1 downward to make the shape of the warp 1 straight and the paper surface smoothness. It is also possible to reduce the thickness of the fabric.
[0018]
FIG. 7 is a cross-sectional view taken along the line II-II ′ of the design diagram showing the complete structure of a 4/1 satin weave monolayer woven fabric without the auxiliary weft shown in FIG. Compared with the shape of 1, it can be understood how the warp of the present invention is formed linearly.
FIG. 5 is a design diagram showing a complete structure of a single-layer fabric in which auxiliary wefts shown in Japanese Patent Laid-Open No. 2-68383 are arranged.
Referring to FIG. 8 which is a cross-sectional view taken along the line III-III ′ in FIG. 5, auxiliary wefts are arranged in a recess formed in a portion where the warp 1 rises from below to above, for example, the warp 1 is the weft 1 It can be seen that the auxiliary weft yarn 2 ″ is arranged in the recess formed in the portion rising from below the weft yarn 3 ′ to improve the smoothness, and the configuration is completely different from the present invention.
Further, in the example of FIG. 5, since the auxiliary weft is woven from the upper side at the portion where the warp crosses from the upper side to the upper side, the auxiliary weft retainability of the auxiliary weft as described above is small because the force for weaving the auxiliary weft downward in the structure is small. There were problems such as not enough.
[0019]
2 and 3 are design diagrams showing the complete structure of another embodiment of the present invention.
The embodiment of FIG. 2 is an embodiment in which the main fabric is a 3/1 twill, and the embodiment in FIG. 3 is an embodiment in which the main fabric is broken 3/1. The symbols for warp and weft are the same as in FIG.
[0020]

[0023]
【The invention's effect】
As described above, since the present invention is a single-layered weft wear type, the thickness is small, the water retention is small, the freeness is good, and the wear resistance is good.
Further, since the auxiliary wefts are arranged, the surface smoothness, the fiber supportability of the wefts, and the wire mark property are good.
In addition, since the warp is formed in a straight line, the thickness can be further reduced and the elongation rigidity can be improved.
Further, since the weaving of the auxiliary weft is strong, the retention of the auxiliary weft is good, and the auxiliary weft does not move and the fibrillation resistance is also good. Further, since the auxiliary weft is firmly bent and the shape is stabilized, there is no inconvenience in the weaving operation.
