Description

The present invention relates to a woven fabric having at least ground warp threads, ground weft threads, weft flat threads, and the like, and a method for producing the woven fabric.

Conventionally, foil woven fabrics are known (Patent Document 1).
In this foil woven fabric, the Karami yarn 1 and the ground warp yarn 2 are warped as a set of warp yarns A, and the ground weft yarns are woven into the warp yarns in a plain weave. Then, it is woven so as to be bound by a kalami thread, and a foil thread is used for at least a part of the ground warp thread, the ground weft thread and the picture weft thread.

Japanese Unexamined Patent Publication No. 11-43844

However, in the foil woven fabric described in Patent Document 1, as described in paragraph 0012, the flat foil yarn is exposed from between the picture weft yarns 4a to 4d and the warp yarn A on the black background, but the flat foil yarn is exposed. Since the portion that is not used is a hole that penetrates between the picture weft threads 4a to 4d and the warp thread A on a black background, the woven fabric has a very large gap.
Further, in the foil woven fabric described in Patent Document 1, since the flat foil yarn is only exposed in the same manner on either the front or back surface, different properties cannot be exposed on the front and back surfaces.

Therefore, the present invention has "improved woven fabric density" and "heterogeneous exposure on the front and back surfaces" by having a flat covering region in which the weft plain yarn partially organized by the ground warp yarn is arranged so as to cover the ground weft yarn. It is an object of the present invention to provide a woven fabric capable of realizing the above, and a method for manufacturing the woven fabric.

The woven fabric 1 according to the present invention is a woven fabric having at least ground warp threads, ground weft threads and weft plain threads, and the ground warp threads and ground weft threads form a regular ground structure, and at least a part of the weft plain threads is formed. The woven fabric is partially organized by the ground warp threads, and the woven fabric has a flat covering area arranged so that the weft flat threads cover the ground weft threads.
The "weft flat yarn" in the present invention is a flat yarn used as a weft.
Further, the "flat yarn" in the present invention is a yarn including a yarn having a longitudinal direction in the cross-sectional shape, such as a substantially rectangular shape or a substantially elliptical shape in the cross-sectional shape, and is, for example, a foil yarn or an interference coloring. It may be a yarn or the like, or a tasuki twisted yarn described later using these foil yarns or interference coloring yarns.

The second feature of the woven fabric 1 according to the present invention is that, in addition to the first feature, the width value of the weft flat yarn is larger than the diameter value of the ground weft yarn.
The "width 4W of the weft flat thread 4" in the present invention is the width 4W of the weft flat thread 4 in a plan view, and when the cross-sectional shape of the weft flat thread 4 has a longitudinal direction such as a rectangular shape or a substantially elliptical shape. , Means the length in the longitudinal direction in the cross-sectional shape of the weft flat thread 4.

The third feature of the woven fabric 1 according to the present invention is that, in addition to the first or second feature, the weft plain yarn has at least a portion having a flat cover factor value of 10 or more.
The "flat cover factor value CF of the weft flat thread 4" in the present invention is a value represented by the following formula (1).

The fourth feature of the woven fabric 1 according to the present invention is that, in addition to the above-mentioned first to third features, the ground warp yarn that organizes the weft flat yarn is a split yarn.

The fifth feature of the woven fabric 1 according to the present invention is that, in addition to the above-mentioned first to fourth features, at least a part of the weft flat yarn is a foil yarn and / or a yarn using a foil yarn.

The sixth feature of the woven fabric 1 according to the present invention is that, in addition to the features 1 to 5, at least a part of the weft flat yarn is a yarn using an interference coloring yarn and / or an interference coloring yarn. is there.

The seventh feature of the woven fabric 1 according to the present invention is a woven fabric having at least ground warp yarns, ground weft yarns and weft coat yarns, and the ground warp yarns and ground weft yarns form a regular ground structure, and the weft At least a part of the yarn is partially organized by the ground warp yarn, and the woven fabric has a covering region arranged so that the weft yarn covers the ground weft yarn.
The "weft coat" in the present invention is a coat (cover) used as a weft.
Further, the "thread to be threaded" in the present invention is not only a plain yarn having a longitudinal direction in the cross-sectional shape such as a substantially rectangular shape or a substantially elliptical shape in the cross-sectional shape, but also other than the plain yarn (the cross-sectional shape thereof is A thread that also includes a thread that does not have a longitudinal direction, such as a substantially circular shape or a substantially triangular shape, and is, for example, a foil thread or an interference coloring thread, or a thread using these foil threads or an interference coloring thread, which will be described later. Not only the Tasuki twisted yarn but also the round twisted yarn, the bellows twisted yarn, the Hagoromo twisted yarn, the Bryan twisted yarn and the like may be used.

Due to these characteristics, unlike Patent Document 1, the weft flat yarn 4 is raised by having a flat covering region 6 in which the weft flat yarn 4 partially woven by the ground warp yarn 2 is arranged so as to cover the ground weft yarn 3. It is possible to weave at a high density, resulting in a woven fabric with few gaps (“improvement of woven fabric density”).
At the same time, if the properties of the weft flat thread 4 of the flat covering area 6 and the properties of the ground weft thread 3 and the like of the flat covering area 6 (the portion covered by the weft flat thread 4) are different, the front and back surfaces of the woven fabric 1 can be used. It can be said that different properties can be exposed (“different exposure on the front and back surfaces”), and the weft flat thread 4 is less likely to be crushed (“suppression of crushing of the weft flat thread 4”).

Further, by making the value of the width 4W of the weft flat yarn 4 larger than the value of the diameter 3L of the ground weft yarn 3, the ground weft yarn 3 can be covered with the weft flat yarn 4 more reliably, and further "improvement of the woven fabric density". "And" different exposure on the front and back "can be achieved.

Further, by setting the flat cover factor value CF of the weft flat yarn 4 to 10 or more, it is possible to cover the ground weft yarn 3 with the weft flat yarn 4 more reliably, such as "improvement of woven fabric density" and "on the front and back sides". Further realization of "different exposure" can be achieved.

Then, by making the ground warp yarn 2 (flat ground warp yarn 2a) that organizes the weft flat yarn 4 into a split yarn, even in the portion where the ground warp yarn 2 organizes the weft flat yarn 4, weft from the gap between the split yarns. The plain yarn 4 is further exposed, and the exposed area of the weft plain yarn 4 in the woven fabric 1 can be increased.
In addition, at least a part of the weft flat yarn 4 may be a foil yarn or the like, or at least a part of the weft flat yarn 4 may be an interference coloring yarn or the like.
In addition, the weft flat yarn 4 may be replaced with the weft yarn 4', and the weft yarn 4'may have a covering region 6'arranged so as to cover the ground weft yarn 3.

The method for producing a woven fabric 1 according to the present invention is a method for producing a woven fabric having at least a ground warp yarn, a ground weft yarn, and a weft yarn, and at least a part of the weft yarn is partially textured with the ground warp yarn. When the weft yarn is driven in, the winding of the ground warp yarn is stopped and the weft yarn is driven so that at least a part of the weft yarn is placed so as to cover the ground weft yarn. That is the first feature.

Due to this feature, after driving the ground weft thread 3, the winding of the ground warp thread 2 is stopped, and by driving the weft thread 4', the weft thread 4'is arranged so as to cover the ground weft thread 3. , Unlike Patent Document 1, at least a part of the weft yarn 4'can be woven at a high density, and a woven fabric having a small gap can be manufactured (“improvement of woven fabric density”).
At the same time, the properties of the weft yarn 4'of the covering region 6'arranged so as to cover the ground weft 3 and the ground weft 3 etc. of the covering region 6'(the portion covered by the weft yarn 4'). By making the properties different in the above, it is possible to realize "different exposure on the front and back surfaces", and it can be said that the weft yarn 4'is less likely to be crushed ("suppression of crushing of the weft yarn 4'").

According to the woven fabric according to the present invention and the method for producing a woven fabric, "improvement of woven fabric density" by having a flat covering region in which weft plain yarn partially organized by ground warp yarn is arranged so as to cover the ground weft yarn. Etc. can be realized.

It may be a substantially rectangular shape, a substantially polygonal shape such as a substantially pentagon or a substantially hexagon, or a substantially star shape).

<Ground warp thread 2>
As shown in FIGS. 1 to 7, the ground warp yarn 2 constitutes the ground structure 5 described later together with the ground weft thread 3 described later, and at the same time partially organizes the weft flat yarn 4 (weft coat yarn 4') described later. It is a thread.
Of the ground warp yarns 2, the flat ground warp yarn 2a that organizes the weft flat yarn 4 may be, for example, a split yarn or a multifilament described later, but conversely, a yarn other than the split yarn (for example, a monofilament). It doesn't matter.

Further, among the ground warp yarns 2, the ground warp yarn 2a'that organizes the weft coat yarn 4'may also be, for example, a split yarn or a multifilament described later, but conversely, a yarn other than the split yarn or the like. It may be (for example, monofilament).
As shown in FIG. 1, the flat ground warp threads 2a and the ground warp threads 2a'partially organize the weft flat threads 4 and the weft cover threads 4', and also the ground weft threads 3.

On the other hand, among the ground warp yarns 2, the ground warp yarns 2 other than the weft plain yarn 4 and the weft coat yarn 4'(the textured ground warp yarn 2b that constitutes the ground structure 5 together with the weft flat yarn 4) may be a split yarn or the like. , A yarn other than the split yarn (for example, monofilament) may be used.
As shown in FIG. 1, the textured ground warp yarn 2b is composed of only the ground weft yarn 3.

<Separation thread, etc.>
When the flat ground warp yarn 2a, the ground warp yarn 2a', or the like is a split yarn, the fineness (total fineness) of the entire split yarn is 1 dtex or more and 300 dtex or less, preferably 5 dtex or more and 200 dtex or less, and further. It may be preferably 10 dtex or more and 100 dtex or less (33 dtex or the like).
The single fiber fineness of the split yarn is 0.1 dtex or more and 30.0 dtex or less, preferably 0.5 dtex or more and 20.0 dtex or less, more preferably 1.0 dtex or more and 10.0 dtex or less (about 2.0 dtex (1.375 dtex)). Etc.).

Further, it can be said that the flat ground warp yarn 2a or the like is a multifilament, and even in that case, the total fineness is 1 dtex or more and 300 dtex or less, preferably 5 dtex or more and 200 dtex or less, and more preferably 10 dtex or more and 100 dtex or less (33 dtex or the like). good.
In this case, the single fiber fineness of each filament is 0.1 dtex or more and 30.0 dtex or less, preferably 0.5 dtex or more and 20.0 dtex or less, and more preferably 1.0 dtex or more and 10.0 dtex or less (about 2.0 dtex (1. 375dtex) etc.) may be used.

When the ground warp yarn 2 (for example, the tissue ground warp yarn 2b) is neither a split yarn nor a multifilament (that is, a monofilament), the total fineness is 1 dtex or more and 300 dtex or less, preferably 5 dtex or more and 200 dtex or less. More preferably, it may be 10 dtex or more and 100 dtex or less (22 dtex or the like).
With respect to the ground warp threads 2 (flat ground warp threads 2a, ground warp threads 2a', woven ground warp threads 2b) described so far, the warp jumps (weft threads (weft flat thread 4 and weft cover thread 4', etc.) are warp threads (flat ground warp threads 2a, etc.). The distance (distance exposed on the surface 1a of the woven fabric 1) over the ground warp yarn 2a'etc.) is not particularly limited, but is, for example, 0.1 mm or more and 5.0 mm or less, preferably 0.5 mm or more. It may be 4.5 mm or less, more preferably 1.0 mm or more and 4.0 mm, and it can be said that a large warp jump affects the feel, and a small warp jump affects the gloss. , The jump of the weft yarn (weft flat yarn 4 or weft coat yarn 4'etc.) (not bound by the warp yarn, but exposed on the surface 1a of the woven fabric 1) rather than the jumping of the warp yarn (flat ground warp yarn 2a, ground warp yarn 2a', etc.) It can be said that the distance) has an effect.

The above-mentioned flat ground warp yarn 2a (ground warp yarn 2a') partially organizes the weft flat yarn 4 (weft coat yarn 4') (partially above the weft flat yarn 4 (weft coat yarn 4'). Not only the ground weft thread 3 is also organized (overcoming the ground weft thread 3), so only the ground weft thread 3 is organized (overcoming only the ground weft thread 3). It can be said that the warp skipping distance (distance exposed on the surface 1a of the woven fabric 1) is longer than that of the tissue warp yarn 2b (particularly during weaving) (see reference numeral X in FIG. 1).
The specific value of the density of the ground warp yarn 2 (ground warp density) is also not particularly limited, but is, for example, 100 yarns / 10 cm or more and 1200 yarns / 10 cm or less, preferably 150 yarns / 10 cm or more and 1000 yarns / 10 cm or less. More preferably, it may be 200 pieces / 10 cm or more and 800 pieces / 10 cm or less (347 pieces / 10 cm or the like).

<Ground weft 3>
As shown in FIGS. 1 to 7, the ground weft thread 3 is a thread that constitutes the ground structure 5 described later together with the above-mentioned ground warp thread 2.
As described above, the ground weft thread 3 may be woven (drived) not only in one type but also in a plurality of types in one woven fabric 1.

Here, the different types of ground weft yarns 3 are glossy yarns (bright yarns), semi-dull yarns, and dull yarns (the amount of titanium oxide added (content) is different), and the total fineness. The number of filaments is different, the cross-sectional shape of each fiber is different (round cross section, irregular cross section, etc.), the presence or absence of predetermined processing such as woolly processing is different, and these are combined and different. You may be.
The different types of ground weft threads 3 are woven (drived) by different shuttles (shuttles, chome) in the loom for weaving the woven fabric 1.
Such ground weft yarn 3 may be, for example, the above-mentioned glossy yarn, semi-dull yarn, dull yarn, round twisted yarn using foil yarn or interference coloring yarn described later, bellows twisted yarn, hagoromo twisted yarn, briyan twisted yarn or the like. There may be.

<Diameter 3L of ground weft thread 3>
The diameter 3L of the ground weft thread 3 described above is the diameter if the cross-sectional shape of the ground weft thread 3 is substantially circular, and the major axis (or minor axis) if the cross-sectional shape of the ground weft thread 3 is substantially elliptical. If the cross-sectional shape of the ground weft thread 3 is irregular, the longest distance (or the shortest distance) may be the longest distance (or the shortest distance) from one peripheral edge to another substantially opposite peripheral edge in the cross-sectional shape.
Further, the diameter 3L of the ground weft 3 may be calculated from the fineness (dtex) of the ground weft 3 and the specific gravity (g / cm ³ ) of the material, assuming that the cross-sectional shape of the ground weft 3 is substantially circular. If the fineness is "Adtex" and the specific gravity is "Bg / cm ³ ", the diameter 3L of the ground weft 3 is "3L≈11.3 × √ (A / B) μm".
In addition, regarding the diameter 3L of the ground weft 3, the ground weft 3 is imaged with an electron microscope such as a scanning electron microscope (SEM), and the diameter 3L of the ground weft 3 is actually measured in the photograph (image) taken. This actual measurement method is also not particularly limited, but for example, in the captured image, the length of the ground weft 3 along the direction substantially orthogonal to the longitudinal direction (length direction) of the ground weft 3 ( The value of (width) is set to the value of the diameter 3L (or width 3W) of the ground weft thread 3, or the length of the ground weft thread 3 along a direction substantially orthogonal to the longitudinal direction of the ground weft thread 3 in the captured image. If the value of the sword differs depending on the actual measurement location, the value of the length of the ground weft thread 3 along the substantially orthogonal direction is measured at a plurality of locations, and the average value of the plurality of measured values or the average value of the actual measurement values is used. The minimum value, the maximum value, the intermediate value, and the like may be actually measured by a method in which the diameter of the ground weft 3 is 3 L (or the width is 3 W).

The diameter 3L of the ground weft 3 may be smaller than the value of the width 4W of the weft flat yarn 4 described later (or the width 4W'of the weft yarn 4'described later).
When one woven fabric 1 has a plurality of types of ground weft yarns 3, the diameter 3L of at least one type of ground weft yarn 3 has a width of 4W of the weft flat yarn 4 (or a width of 4W'of the weft yarn 4'). It can be said that it should be smaller than the value of.

The specific value of the diameter 3L of the ground weft 3 is not particularly limited, but may be, for example, 10 μm or more and 1000 μm or less, preferably 20 μm or more and 500 μm or less, and more preferably 30 μm or more and 300 μm or less (about 124 μm or the like). ..
The specific value of the fineness (total fineness) of the ground weft 3 is also not particularly limited, but is, for example, 10 dtex or more and 2000 dtex or less, preferably 20 dtex or more and 1000 dtex or less, preferably 30 dtex or more and 500 dtex or less (167 dtex or the like). It doesn't matter.
The specific value of the density of the ground weft thread 3 (ground weft density) is also not particularly limited, but is, for example, 100 threads / 10 cm or more and 1000 threads / 10 cm or less, preferably 150 threads / 10 cm or more and 800 threads / 10 cm or less. More preferably, it may be 200 pieces / 10 cm or more and 600 pieces / 10 cm or less (165 pieces / 10 cm, 180 pieces / 10 cm, 250 pieces / 10 cm, etc.).

<Weft flat thread 4>
As shown in FIGS. 1 to 7, the weft flat yarn 4 is a yarn in which at least a part thereof is partially organized by the above-mentioned ground warp yarn 2 and arranged so as to cover the above-mentioned ground weft yarn 3. The point that the weft flat yarn 4 is partially organized by the ground warp yarn 2 will be described in detail later.
The weft flat thread 4 may have a longitudinal direction in its cross-sectional shape, such as a substantially rectangular shape or a substantially elliptical shape.

At least a part of the weft flat yarn 4 may be a yarn using a foil yarn and / or a foil yarn described later, or a yarn using an interference coloring yarn and / or an interference coloring yarn described later.
In addition, the weft flat yarn 4 may be a yarn other than a yarn using a foil yarn or an interference coloring yarn, and may be, for example, a glossy yarn.

<Weft yarn 4'>
Instead of the weft flat yarn 4 described above, the woven fabric 1 may have a weft yarn 4'.
As shown in FIG. 7, the weft yarn 4'is also a yarn in which at least a part thereof is partially organized by the above-mentioned ground warp yarn 2 and arranged so as to cover the above-mentioned ground weft yarn 3. The cross-sectional shape of the weft yarn 4'is not particularly limited as long as it is arranged so as to cover the ground weft yarn 3. The point that the weft yarn 4'is partially organized by the ground warp yarn 2 will be explained in detail later.

That is, the weft yarn 4'includes not only the weft plain yarn 4 described above, but also yarns other than the weft plain yarn 4 (the cross-sectional shape thereof does not have a longitudinal direction such as a substantially circular shape or a substantially triangular shape).
At least a part of the weft yarn 4'may be a foil yarn or the like described later, or an interference coloring yarn described later, and the weft yarn 4'is also other than the foil yarn or the interference coloring yarn. It may be, for example, a glossy thread or the like.

<Foil thread, etc.>
The "foil thread" in the present invention is a Japanese paper such as ganpishi or Torinoko paper, or a synthetic resin non-woven fabric to which foil or raden such as gold, silver, aluminum, zinc, or stainless steel is attached with lacquer or sulfur. It may be a finely cut thread, or a finely cut thread obtained by adhering aluminum, copper, zinc, stainless steel, etc. to a synthetic resin film such as polyester, polyurethane, or polyamide (evaporation, sputtering, etc.), and the cutting foil. It can also be called a thread, a flat foil thread, a slit thread, or a lame thread.
The foil yarn itself can be said to have a substantially rectangular cross-sectional shape and has a longitudinal direction (that is, the foil yarn itself can be said to be a weft flat yarn 4).

The yarn using such a foil yarn is, for example, a yarn in which a foil yarn is wound tightly around a synthetic resin such as rayon or polyamide, a core yarn such as silk, a metal yarn, and a water-soluble yarn (round twisted yarn). In the case of round twisted yarn, the foil yarn is wound without gaps, so it can be said that the core yarn is not exposed.
Since it can be said that the cross-sectional shape of the circularly twisted yarn depends on the cross-sectional shape of the core yarn (similar to the cross-sectional shape of the core yarn), when the cross-sectional shape of the core yarn does not have a longitudinal direction such as a substantially circular shape. Does not have a longitudinal direction in the cross-sectional shape of the circularly twisted yarn, and when the cross-sectional shape of the core yarn has a longitudinal direction such as a substantially rectangular shape, the cross-sectional shape of the circularly twisted yarn also has a longitudinal direction (that is, the circularly twisted yarn). Can be said to be at least the weft yarn 4').

Further, the yarn using the foil yarn is, for example, a synthetic resin such as rayon or polyamide, or a core yarn such as silk, metal yarn, or water-soluble yarn, and the foil yarn is wound around the core yarn at intervals (or). It may be a twisted yarn (also referred to as a bellows twisted yarn), and in the bellows twisted yarn, it can be said that the core yarn is exposed because the foil yarns are wound at intervals.
Since it can be said that the cross-sectional shape of the bellows plying also depends on the cross-sectional shape of the core yarn (similar to the cross-sectional shape of the core yarn), when the cross-sectional shape of the core yarn does not have a longitudinal direction such as a substantially circular shape. Does not have a longitudinal direction in the cross-sectional shape of the bellows plying, and when the cross-sectional shape of the core yarn has a longitudinal direction such as a substantially rectangular shape, the cross-sectional shape of the bellows plying also has a longitudinal direction (that is, the bellows twisted yarn). Can be said to be at least weft yarn 4').

Further, the yarn using the foil yarn is, for example, a yarn obtained by twisting the foil yarn with a synthetic resin such as rayon or polyamide, or a core yarn such as silk, metal yarn, or water-soluble yarn (also referred to as hagoromo twisted yarn). In the Hagoromo twisted yarn, the core yarn and the foil yarn are simply twisted together, so it can be said that the core yarn is naturally exposed.
Since it can be said that the cross-sectional shape of the hagoromo plyed yarn also depends on the cross-sectional shape of the core yarn (similar to the cross-sectional shape of the core yarn), when the cross-sectional shape of the core yarn does not have a longitudinal direction such as a substantially circular shape. Does not have a longitudinal direction in the cross-sectional shape of the hagoromo plyed yarn, and when the cross-sectional shape of the core yarn has a longitudinal direction such as a substantially rectangular shape, the cross-sectional shape of the hagoromo plyed yarn also has a longitudinal direction (that is, the hagoromo twisted yarn). Can be said to be at least weft yarn 4').

In addition, the yarn using the foil yarn is, for example, a foil yarn as a core yarn, and two yarns such as synthetic resin such as polyester or polyamide, silk, metal yarn, and water-soluble yarn are used for the core yarn. It may be twisted in a twisted shape (also called a tasuki twisted yarn), and in the tasuki twisted yarn, a core yarn (foil yarn) and a yarn such as polyester are twisted in a twisted shape, so the core yarn is naturally It can be said that it is exposed.
Since the cross-sectional shape of the Taski twisted yarn depends on the cross-sectional shape of the core yarn (foil yarn) (similar to the cross-sectional shape of the core yarn), it can be said to be substantially rectangular and has a longitudinal direction (that is, the Taski twisted yarn). Can be said to be weft plying 4).

In addition, the yarn using the foil yarn is, for example, a synthetic resin such as rayon or polyamide, a core yarn such as silk, metal yarn, or a water-soluble yarn, and a synthetic resin yarn such as polyester or polyamide together with the foil yarn. The core yarn may be twisted together (also referred to as Bryan twisted yarn), and in the Briyan twisted yarn, the core yarn is naturally exposed because the core yarn and the yarn such as foil yarn and polyester are simply twisted together. It can be said that.
Since it can be said that the cross-sectional shape of the Bryan twisted yarn also depends on the cross-sectional shape of the core yarn (similar to the cross-sectional shape of the core yarn), when the cross-sectional shape of the core yarn does not have a longitudinal direction such as a substantially circular shape. Does not have a longitudinal direction in the cross-sectional shape of the Bryan twisted yarn, and when the cross-sectional shape of the core yarn has a longitudinal direction such as a substantially rectangular shape, the cross-sectional shape of the Bryan twisted yarn also has a longitudinal direction (that is, the Briyan twisted yarn). Can be said to be at least weft yarn 4').

<Interference coloring thread, etc.>
The "interference coloring thread" in the present invention is a thread that develops structural color by utilizing the principle of light interference, and is configured by laminating a plurality of layers.
In such an interference coloring thread, the colors that interfere with each other and strengthen each other are determined according to the thickness and the viewing angle (when the interference coloring thread of a certain thickness is viewed at a certain angle, for example, blue strengthens each other and becomes blue. It can be seen, but when the thickness and angle change, the blue color does not strengthen each other, but different colors such as red strengthen each other and appear as the red color).

The plurality of layers constituting the interference coloring yarn include at least a film in which a plurality of synthetic resin layers such as polyester and polyamide are laminated, and in addition to this film, a resin coating layer and a metal adhesion layer are included. It may be.
The interference coloring yarn is formed by laminating a metal adhesion layer and a resin coating layer in this order on, for example, one surface of one film, or in addition to this configuration, on the other surface of the film. On the other hand, it may be configured by laminating resin coating layers.

Further, in the interference coloring thread, for example, a metal adhering layer and another film are laminated in this order on one surface of one film (so that the metal adhering layer is sandwiched between the two films). A resin coating layer, a metal adhesion layer, another resin coating layer, and another film are laminated in this order (2) on one surface of one film. A metal adhering layer may be sandwiched between the two resin coating layers, and the three layers may be laminated so as to be sandwiched between the two films).
Regarding the film constituting the interference coloring yarn, the number of layers of the synthetic resin in the film is not particularly limited, but may be several hundred, for example. The film itself is not colored with a dye or metal.

The resin coating layer constituting the interference coloring yarn may be transparent (colorless and transparent), or may be colored yellow or orange (colored transparent). The resin coating layer may be a layer of a synthetic resin such as polyester, polyurethane, or polyamide.
The metal formed by adhering (depositing, sputtering, etc.) and finely cutting the metal adhering layer constituting the interference coloring yarn may be gold, silver, aluminum, copper, zinc, stainless steel, or the like.

The interference coloring yarn itself can be said to have a substantially rectangular cross-sectional shape and has a longitudinal direction (that is, the interference coloring yarn itself can be said to be a weft flat yarn 4).
Such an interference coloring yarn may be used instead of the foil yarn described above to be a round twisted yarn, a bellows twisted yarn, a hagoromo twisted yarn, a taski twisted yarn, a Bryan twisted yarn or the like (that is, the interference coloring yarn is at least a weft yarn). It can be said that it is 4').

<Width 4W of weft flat yarn 4 and width 4W'of weft yarn 4'>
The width 4W of the weft flat thread 4 described above is the width of the weft flat thread 4 in a plan view (the width when the weft flat thread 4 is viewed in a plan view), and can be said to be the length in the longitudinal direction described above.
On the other hand, the width 4W'of the weft yarn 4'described above is the diameter of the weft yarn 4'if the cross-sectional shape of the weft yarn 4'is substantially circular (that is, if it does not have a longitudinal direction). It can be said that it is the same value as 4L'. It should be noted that the width of the weft yarn 4'when the weft yarn 4'is viewed in a plan view is such that the diameter 4L'of the weft yarn 4'sees as the width 4W'of the weft yarn 4'. I can say.

The width 4W of the weft flat yarn 4 (or the width 4W'of the weft yarn 4') may be larger than the diameter 3L of the ground weft yarn 3 described above.
When one woven fabric 1 has a plurality of types of ground weft threads 3, the width 4W of the weft flat yarn 4 (or the width 4W'of the weft coat yarn 4') is 3L in diameter of at least one type of ground weft yarn 3. It can be said that the larger it is, the better.

The specific value of the width 4W of the weft flat yarn 4 (or the width 4W'of the weft yarn 4') is not particularly limited, but is, for example, 20 μm or more and 2000 μm or less, preferably 30 μm or more and 1000 μm or less, and more preferably 50 μm. It may be 500 μm or more (151.5 μm, 252.5 μm, 378.75 μm, etc.).
If the weft plain yarn 4 (or the weft yarn 4') is the foil yarn or the like described above, or an interference coloring yarn, the width of the weft plain yarn 4 is 4 W (or the width of the weft yarn 4'is 4 W'). Is the value obtained by dividing "30.3 mm", which is one inch of the curved scale, by 80, 120, 200, etc. (also called the cutting width), and when divided by 80, "80 cut (= 0.37875 mm = 378.75 μm)" ) ”, When divided by 120, it is also called“ 120 cut (= 0.2525 mm = 252.5 μm) ”, and when divided by 200, it is also called“ 200 cut (= 0.1515 mm = 151.5 μm) ”.

<Thickness / density of weft flat yarn 4 and thickness / density of weft yarn 4'>
If the cross-sectional shape of the weft flat yarn 4 or the weft coat yarn 4'has a longitudinal direction, it naturally has a lateral direction as well, and the lateral direction is the weft flat yarn 4 or the weft. It can be said that it is the thickness of the thread 4'.
The specific value of the thickness of the weft flat yarn 4 (or the weft yarn 4') is also not particularly limited, but is, for example, 1 μm or more and 100 μm or less, preferably 2 μm or more and 80 μm or less, and more preferably 5 μm or more and 50 μm or less ( It may be 10 μm, 12 μm, 25 μm, etc.).
Further, the specific value of the density (weft flat density, weft density) of the weft flat yarn 4 (or weft coat yarn 4') is also not particularly limited, but is, for example, 100 yarns / 10 cm or more and 1000 yarns / 10 cm or less. , Preferably 120 pieces / 10 cm or more and 800 pieces / 10 cm or less, more preferably 140 pieces / 10 cm or more and 600 pieces / 10 cm or less, and even more preferably 160 pieces / 10 cm or more and 300 pieces / 10 cm or less (165 pieces / 10 cm, 180 pieces). / 10 cm, 250 pieces / 10 cm, etc.) may be used.

<Flat cover factor value CF of weft plain yarn 4, covered factor value CF'of weft yarn 4'>
The "flat cover factor value CF of the weft flat thread 4" in the present invention is a value represented by the following formula (1).
In the formula (1), the unit of the density of the weft plain yarn 4 is "book / 10 cm", the unit of the width 4 W of the weft flat yarn 4 is "mm", and the flat cover factor value CF is the weft flat yarn 4. It can be said that it is a value corresponding to the cover factor in the weft direction along.

Further, the "covered factor value CF'of the weft yarn 4'" in the present invention is a value represented by the following formula (2).
In the formula (2), the unit of the density of the weft yarn 4'is also "book / 10 cm", and the unit of the width 4 W'of the weft yarn 4'is also "mm", and the covered factor value CF It can be said that'is a value corresponding to the cover factor in the weft direction along the weft yarn 4'.

The above-mentioned flat cover factor value CF of the weft plain yarn 4 is not particularly limited, but may be, for example, 10 or more, preferably 15 or more, and more preferably 20 or more (24.9975, 37.875, 63. 125, 94.6875, 113.625, etc.) may be used.
The flat cover factor value CF does not have to have an upper limit, but may be, for example, 300 or less, 200 or less, or 150 or less.
Here, the above-mentioned lower limit value and upper limit value may be combined with each other such as 10 or more and 300 or less and 10 or more and 200 or less to form a range of the flat cover factor value CF.

Further, the above-mentioned covered factor value CF'of the weft yarn 4'is also not particularly limited, but may be, for example, 10 or more, preferably 15 or more, and more preferably 20 or more (24.9975, 37). .875, 63.125, 94.6875, 113.625, etc.) may be used.

Here, the above-mentioned lower limit value and upper limit value may be combined with each other to be in the range of the covered factor value CF', such as 10 or more and 300 or less, or 10 or more and 200 or less.

<Partial structure in which the weft flat yarn 4 and the weft coat yarn 4'compose the ground warp yarn 2>
As described above, at least a part of the weft flat yarn 4 and the weft coat yarn 4'described so far is partially organized by the ground warp yarn 2 (flat ground warp yarn 2a, ground warp yarn 2a'), but the present invention "Partially organized" in the above means that there is a portion of the weft flat yarn 4 that is not organized by the flat ground warp yarn 2a, and that there is a portion of the weft yarn 4'that is not organized by the ground warp yarn 2a'. It means that.

For example, as shown in FIG. 4, in the first flat covering region 6A, one weft warp 4 is organized into one flat warp 2a (the flat warp 2a is the weft warp). After getting over the top of 4 and sneaking underneath), it is organized into another flat warp 2a at intervals of a predetermined number of flat warp threads 2a in the weft direction.
Further, in the example of FIG. 4, focusing on the warp direction, one flat ground warp thread 2a is spaced by a predetermined number of weft flat threads 4 in the warp direction after forming a certain weft flat thread 4. It is vacant and organized in another weft flat thread 4.

On the other hand, since the first flat covering region 6A can be said to be the first covering region 6A', one weft cover yarn 4'is organized into one ground warp yarn 2a'(then). After the ground warp threads 2a'overcome over the weft coat thread 4'and sneak underneath), another coat is spaced apart by a predetermined number of the ground warp threads 2a'in the weft direction. It can be said that it is organized in the ground warp thread 2a'.
Further, in the example of FIG. 4, focusing on the warp direction, one ground warp thread 2a'organizes a certain weft coat thread 4'and then the weft coat thread 4'in the warp direction. It is organized in another weft yarn 4'at intervals of a predetermined number of yarns.

Therefore, a portion of the flat ground warp 2a (ground warp 2a') that is spaced by a predetermined number of threads in the weft direction and a portion of the weft warp 4 (weft warp 4') that is spaced by a predetermined number of threads in the warp direction. However, since it is a portion of the above-mentioned weft flat yarn 4 (weft cover yarn 4') that is not organized by the flat ground warp yarn 2a (ground warp yarn 2a'), the first flat cover region 6A (first cover region 6A'). In, the weft flat yarn 4 (weft coat yarn 4') is partially organized in the flat ground warp yarn 2a (ground warp yarn 2a').
In the first flat covering region 6A (first covering region 6A'), the partial structure of the flat ground warp yarn 2a (ground warp yarn 2a') with respect to the weft flat yarn 4 (weft coating yarn 4') is a satin weave (save). It can be said that it is a weave) organization.

<Ground organization 5 etc.>
As shown in FIGS. 1 to 7, the ground structure 5 is regularly composed (woven) by the above-mentioned ground warp threads 2 (flat ground warp threads 2a, ground warp threads 2a', tissue ground warp threads 2b) and ground weft threads 3. It is an organization.
The ground structure 5 is not particularly limited as long as it is regularly composed of the ground warp threads 2 and the ground weft threads 3, but for example, a plain weave structure, a twill weave structure, a satin weave structure, and the like. It may be.

Here, as shown in FIG. 1, when there is one type of ground weft thread 3 in one woven fabric 1, only the one type of ground weft thread 3 constitutes the ground warp thread 2 and the regular ground structure 5. To do.
In this case, one ground structure 5 naturally becomes one layered structure, and this ground structure 5 may be a plain weave structure.

In addition, as described above, when there are a plurality of types of ground weft threads 3 in one woven fabric 1 (when a plurality of types of ground weft threads 3 are driven by a plurality of shuttles), the ground warp threads 2 are used for each of the ground weft threads 3. And a regular ground structure 5 (each ground weft thread 3 is regularly organized with a ground warp thread 2).
As shown in FIG. 7, this depends on how the weft threads 3 and the ground warp threads 2 (flat ground warp threads 2a (ground warp threads 2a')) are organized, but in one ground structure 5, there are a plurality of types of ground. Each weft 3 may have a plurality of layers (ground structure layers).

In this case, among these plurality of panniculi layers, the panniculus layer in which the structure constituting the flat ground warp threads 2a (ground warp threads 2a') is a plain weave structure can be said to be the main ground structure layer 5a, and the main ground structure layer 5a. The ground weave 3 that organizes the above can be said to be the main ground weft 3a.
Further, among the plurality of ground structure layers, the ground structure layer in which the structure constituting the flat ground warp threads 2a (ground warp threads 2a') is other than the plain weave structure (such as a satin weave structure) can be said to be the sub-ground structure layer 5b. The ground weave 3 that organizes the sub-ground structure layer 5b can also be said to be the sub-ground weave 3b.

The main ground structure layer 5a is a plain weave structure, and a place where the main ground weft 3a is organized with the ground warp thread 2 (a place where the ground warp thread 2 gets over the main ground weft thread 3a and sneaks underneath, so to speak, is in charge. It can be said that there are more stopped places) than any tissue.
Further, since the sub-ground structure layer 5b is other than the plain weave structure (such as a satin weave structure), the place where the sub-ground weft 3b is organized with the ground warp thread 2 (the ground warp thread 2 gets over the top of the sub-ground weft 3b and is below. It can be said that there are fewer places to sneak into the main tissue layer 5a.

In this way, the sub-ground structure layer 5b, which has fewer places organized with the ground warp thread 2 (points locked to the ground warp thread 2), is easy to move in the warp direction with respect to the main ground structure layer 5a (easy to fall). ) Can also be said.
Whether the subordinate structure layer 5b, which is more mobile, moves toward the back surface (the other side) 1b side of the main area structure layer 5a or the front surface (one side) 1a side with respect to the main area tissue layer 5a, is the subject. It depends not only on the structure of the sub-ground structure layer 5b itself, but also on the number of shuttles (in which chome or weft order) in the loom that weaves the woven fabric 1 to drive the sub-ground weft thread 3b. That can be said (see Fig. 1).

<Structure in which weft flat yarn 4 and weft coat yarn 4'easily move (fall easily) in the warp direction and weft order>
This also applies to the partial structure in which the above-mentioned weft flat yarn 4 and weft head yarn 4'consisting with the ground warp yarn 2 (flat ground warp yarn 2a, ground warp yarn 2a').
If there is one type of ground weft 3 in one woven fabric and the ground structure 5 in which the one type of ground weft 3 constitutes the ground warp 2 is a plain weave structure, the weft 4 and the weft coat are used. The partial structure in which 4'consists with the ground warp thread 2 naturally has a portion not organized in the ground warp thread 2 and is naturally locked to the ground warp thread 2 (locked to the ground warp thread 2). It can be said that it is easy to move (fall easily) in the warp direction with respect to the plain weave set 5 because there are fewer places (FIGS. 1 (a) and 1 (c)).

In addition, as shown in FIG. 7, there are a plurality of types of ground weave threads 3 in one woven fabric 1, a plurality of ground structure layers are provided for each of the plurality of types of ground weft threads 3, and the plurality of ground structure layers are present. Even when the main ground structure layer 5a, which is a plain weave structure, is included, the partial structure in which the weft flat thread 4 and the weft coat thread 4'compose the ground warp thread 2 has a portion not organized in the ground warp thread 2. As a matter of course, there are fewer places organized with the ground warp thread 2 (places locked with the ground warp thread 2) by the amount of the warp. It can be said that it is easy to move in the direction (easy to fall).
Does the partial structure of the weft flat yarn 4 and the weft yarn 4', which are easy to move, also move toward the surface (one side) 1a side of the ground weaving structure 5 with respect to the ground structure 5 (particularly, the main ground structure layer 5a)? Whether it moves to the back surface (the other surface) 1b side depends on the partial structure itself, and at what number of shuttles (how many chome or "weft order") in the loom for weaving the woven fabric 1. It can be said that it depends on whether the weft flat yarn 4 or the weft cover yarn 4'is driven in (in the weft order of FIG. 1A, the weft flat yarn 4 and the like easily move in the downward arrow direction in the drawing, but FIG. 1B). In the weft order, the weft flat yarn 4 and the like are on the lower side of the ground warp yarn 2 (flat ground warp yarn 2a and the like) that have already been warped, so that the weft flat yarn 4 and the like are difficult to move downward in the figure).
Further, as indicated by reference numeral X in FIG. 1, in a structure that easily moves in the warp direction, the above-mentioned flat ground warp yarn 2a (ground warp yarn 2a') is only on the weft flat yarn 4 (weft coat yarn 4'). It can also be said that there is a portion (a portion where the warp skipping distance (distance exposed on the surface 1a of the woven fabric 1) is longer) that is continuously overcome even on the ground weft thread 3.

<Manufacturing method of woven fabric 1>
As shown in FIG. 1, the method for producing the woven fabric 1 is a method for producing the woven fabric 1 having at least the above-mentioned ground warp yarn 2, ground weft yarn 3, and weft coat yarn 44'(including weft flat yarn 4).
In this manufacturing method, the ground warp yarn 2 and the ground weft yarn 3 form a regular ground structure 5, and at least a part of the weft coat yarn 4'is partially covered with the ground warp yarn 2 (ground warp yarn 2a', etc.). At the time of organization, after driving the ground weft thread 3, the winding of the ground warp thread 2 is stopped, and the weft thread 4'(including the weft flat thread 4) is driven to make at least a part of the weft thread 4'. , Arrange so as to cover the ground weft thread 3.

Here, in the present invention, "a regular ground structure 5 is formed by the ground warp threads 2 and the ground weft threads 3, and at least a part of the weft coat thread 4'is partially organized by the ground warp threads 2". If the ground warp threads 2 (ground warp threads 2a'and the tissue ground warp threads 2b) are organized with respect to the weft coat threads 4'and the ground weft threads 3 (for each weft coat thread 4'and the ground weft threads 3) (If it gets over or sneaks under it), the ground warp threads 2 and the ground weft threads 3 form a regular ground structure 5, and at the same time, at least a part of the weft coat threads 4'is partially organized by the ground warp threads 2. Means that (see FIG. 1).
Further, in the present invention, "stopping the winding of the ground warp yarn 2 and driving the weft yarn 4'" means not only the case of driving the weft yarn 4'immediately after the winding is stopped, but also the winding. This also includes the case where another one or a plurality of ground weft threads 3 are driven after stopping, and then the weft thread 4'is driven.

In the loom used in this manufacturing method, for example, if there is only one type of ground weft yarn 3, the shuttle of the loom 1 or 2 chome is used together with the weft yarn 4'. In addition, one kind of ground weft thread 3 and weft coat thread 4'driven from the shuttle of 1 and 2 chome is called "1 Koshi" as one set.
If there are two types of ground weft threads 3, the shuttle of the loom is 1 to 3 chome in combination with the weft coat thread 4'. It should be noted that the two types of ground weft threads 3 and weft coat threads 4'driven from the shuttles of 1-3 chome are called "1 koshi" as one set.

As shown in FIG. 1, the weft threads (ground weft thread 3 and weft cover thread 4') for each "1 koshi" are substantially parallel in cross-sectional view and plan view when they are driven (the ground weft thread 3 and the weft cover thread 4'). It can be said that the density (weft density) is low because it is almost in parallel).
However, by performing the above-mentioned structure in which the weft yarn 4'moves easily in the warp direction, the weft order, and the winding stop of the ground warp yarn 2 at a predetermined timing, the ground weft yarn 3 and the weft yarn 4'are made into the ground warp yarn 2. The weft yarn 4'is arranged so as to cover the ground weft yarn 3 on the surface (one side) 1a side of the woven fabric 1. That is, by this manufacturing method, the weft yarn 4'can be woven at a higher density, and the woven fabric 1 having a small gap can be manufactured.

For example, even if two types of ground weft threads 3 and weft threads 4'are driven in at a weft density of 250 threads / 10 cm (that is, a total weft density of 750 threads / 10 cm at 1-3 chome), the weft coat is used. The weft has a weft density of 485 threads / 10 cm by performing the structure in which the threads 4'easily move in the warp direction, the weft order, and the winding stop of the ground warp threads 2 at predetermined timings.
Similarly, for example, even if two types of ground weft threads 3 and weft coat threads 4'are driven at a weft density of 180 threads / 10 cm (total weft density of 540 threads / 10 cm at 1-3 chome), 349 weft threads are used. The weft density is / 10 cm, and even if two types of ground weft threads 3 and weft coat threads 4'are driven at a weft density of 165 threads / 10 cm (total weft density of 495 threads / 10 cm at 1-3 chome), the weft threads are still present. The weft density is 320 lines / 10 cm.
In the above-mentioned manufacturing method of the woven fabric 1, after the ground weft 3 is driven, the winding of the ground warp 2 is stopped, and the weft 4 (weft coat 4') is driven into the ground weft 3 and the weft 4 (weft). Alternatively, the specific value of the combined density (finished weft density) of the weft yarn 4') is also not particularly limited, but for example, 100 yarns / 10 cm or more and 1200 yarns / 10 cm or less, preferably 150 yarns / 10 cm or more. It may be 1000 pieces / 10 cm or less, more preferably 200 pieces / 10 cm or more and 800 pieces / 10 cm or less (320 pieces / 10 cm, 349 pieces / 10 cm, 485 pieces / 10 cm, etc.).

<Flat covering area 6, covering area 6'>
As shown in FIGS. 1 to 6 and 7, the woven fabric 1 has a weft according to the structure in which the weft flat yarn 4 and the weft coat yarn 4 ′ move easily in the warp direction, the weft order, and the manufacturing method of the woven fabric 1. The flat yarn 4 and the weft yarn 4'have a flat covering region 6 and a covering region 6'arranged so as to cover the ground weft yarn 3.
As shown in FIGS. 2 to 6, when the weft flat yarn 4 (weft coat yarn 4') is an interference coloring yarn, in the first flat cover region 6A and the second flat cover region 6B, each region 6A, If the orientation of the weft plain yarn 4 is different for each 6B, this means that when viewed as one woven fabric 1, even though the interference coloring yarns of the same thickness are used for each weft flat yarn 4, each region The colors look different for each of 6A and 6B.

In addition, in FIGS. 2 to 6, "the direction of the weft flat yarn 4 is different for each region 6A and 6B" means that the surface (exposed surface) of the weft flat yarn 4 is substantially along the warp direction to the back side or the front side. The orientation of the surface of the weft flat thread 4 is different from each other due to the inclination, a part of the weft flat thread 4 being twisted to the back side or the front side, or the weft flat thread 4 itself being curved. Means.
Further, on the surfaces of the first flat covering region 6A and the second flat covering region 6B (first covering region 6A'and second covering region 6B'), the weft flat yarn 4 (weft covering region 4') is partially structured. The number of exposed locations (number of warp skips) of the ground warp threads 2 (flat ground warp threads 2a, ground warp threads 2a') is not particularly limited, and each area 6A, 6B (6A', 6B'). It may be different for each.

Hereinafter, Examples 1 to 8 of the woven fabric 1 according to the present invention will be referred to.
<Example 1>
In the woven fabric 1, among the ground warp yarns 2, the flat ground warp yarn 2a that organizes the weft flat yarn 4 is a polyester monofilament yarn (247 yarns / 10 cm of 22 dtex), and the tissue ground warp yarn 2b is a polyester multifilament yarn (347 yarns / 10 cm of 33 dtex). Of the ground weft threads 3, the secondary weft yarn 3b to be driven into the 1-chome of the weaving machine is a polyester woolly processed yarn (250 yarns of 167 dtex / 10 cm), and the main ground weft yarn 3a to be driven into the 2-chome of the weaving machine is a polyester woolly processed yarn. (250 yarns / 10 cm of 167 dtex), and the weft plain yarn 4 to be driven into the 3-chome of the weaving machine is made of foil yarn (250 yarns / 10 cm of width 4 W "80 cut"). When a regular ground structure 5 is formed by the weft thread 3a and at least a part of the weft flat thread 4 is partially organized by the flat ground warp thread 2a, the ground warp thread 2 is driven after the main ground weft thread 3a of 2-chome is driven. By stopping the winding of (flat ground warp yarn 2a and woven ground warp yarn 2b) and immediately after that, by driving in the weft flat yarn 4 of 3-chome, at least a part of the weft flat yarn 4 is arranged so as to cover the ground weft yarn 3. Then, the woven fabric 1 of Example 1 was woven.
In the woven fabric 1 of Example 1, the sub-ground weft 3b of 1-chome is composed of the plain weave 2a, the sub-texture layer 5b is a satin weave structure, and the main weave 3a of 2-chome is the plain weave 2a. The main structure layer 5a to be composed is a plain weave structure, the weft plain weave 4 of 3-chome is a satin weave structure, and the sub-ground weft 3b of 1-chome is a tissue ground warp. The ground structure 5 constituting 2b is a plain weave structure.
