[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a woven fabric having a mysterious color exhibiting a so-called iridescent color and a method for producing the same.

[0002]

2. Description of the Related Art As a basic manufacturing technique of a technique for manufacturing a fabric having an iridescent color, Yoshikazu Yoshida, published on January 22, 1933, Textile design and manufacturing (Maruzen) p182-183. In Chameleon taffeta manufacturing method. That is, "a method of using one color for the warp thread and two colors for the weft thread and weaving this into the same mouth.
It is possible to weave one color of weft as a color, but the effect is not as good as the former ... "
It has been known for a long time.

After that, various improvements were further made in order to obtain a fabric having a higher-grade iridescent color.
In Japanese Patent Publication No. 9-117764, one of the warp threads and the weft threads constituting the woven fabric is a thread of three or four colors of A, B, C, (D), and three or more threads of the same color are used to give an iridescent color. Surrounding B, which is the intermediate color between A and C, which is not the center of color development, and the arrangement order of the yarns constituting the fabric is A, B, C, (D), and the weave design is relative to the fabric surface of B. Floating / sinking ratio = 3 or more, and the floating number of B is 1.5 of A, C, (D)
An improved method for obtaining an iridescent fabric by doubling or more is disclosed.

Further, in Japanese Patent Application Laid-Open No. 8-60563, a multi-ply of a warp yarn (desirably a natural fiber or an improved natural fiber spun yarn) and a weft yarn (desirably silk or recycled cellulose or synthetic fiber) having a metachromatic property is used. There is disclosed an improved method of obtaining an iridescent woven fabric even in a universal weaving structure by forming the filament yarn) and dyeing the warp yarn and the weft yarn in different colors.

In addition, there is a method of using a processed thread in which a metal is vapor-deposited on the surface of a fiber to be used, and, as seen in Japanese Patent Laid-Open No. 7-42070, there is a retroreflective property which is one of anisotropic reflection characteristics. A method of obtaining an iridescent fabric using glass beads or an inorganic fluorescent substance as a coloring agent for application is also disclosed.

Further, Japanese Patent Application Laid-Open No. 11-107110 discloses a method of obtaining an iridescent woven fabric by combining an interference coloring fiber and a natural fiber, a chemical fiber or a mixed fiber of a natural fiber and a chemical fiber. This invention is different from the conventional invention of imparting an iridescent color by the combination of weaving conditions or weaving textures of different-colored fibers, and the fiber-forming polymer having a large difference in birefringence is used to exhibit iridescent color.
This is a method of expressing an iridescent color by utilizing the interference color expressing ability of the composite fiber in which five or more layers are alternately laminated in a thin layer of 02 to 0.3 μm.

[0007]

However, the chameleon taffeta manufacturing method described in the inner and outer woven fabric structure and manufacturing science (Maruzen), which is a classical basic technique for manufacturing a fabric having an iridescent color, and JP-A-49-1177764. Japanese Patent Laid-Open No. 606053/1996 and the like, a method for providing an iridescent color based on a fabric configuration method based on the arrangement / arrangement state setting and the fabric configuration organization setting in a combination of different-colored fibers Although it was possible to add the above, it was not possible to obtain an iridescent fabric that lacked a sense of quality and had mystery.

That is, even if the chameleon taffeta is woven by simply using three colors having different hues, the three colors are mixed to give a dark and cloudy shade, or the color change is scarce, whereby an iridescent fabric is obtained. I can't.

For example, when a woven fabric is woven using red and magenta as warp threads and yellow as weft threads, the mixed color has a reddish hue, but since similar colors are used, the change in color must be small. I don't get. When red and green are used for the warp threads and blue is used for the weft threads, the change in color is clear, but a blackish and muddy hue is obtained.

Even if two similar colors are used for the warp, the change in color is small. For example, in a combination of relatively similar colors such as red and magenta and blue and cyan, the mixed color will have a clear lightness and saturation that will not deteriorate, but the color change must be poor. . In addition, in the combination of red and green, blue and green, red and blue, etc., the mixed color becomes dark,
Since the lightness is reduced, the woven fabric has a dark atmosphere.

On the other hand, the combinations of red and cyan, green and magenta, blue and yellow, white and black, etc. have the opposite colors (complementary colors), so the mixed color becomes gray and the woven fabric is dull. It becomes a shade.

Similarly, with regard to the weft yarn, if two different colors used for the warp yarn are used, three color changes can be obtained. However, when the same color or a similar color as the warp yarn is used,
Only two color changes are required. The same can be said when one color of warp and two colors of weft are driven in the same arrangement in the same arrangement.

The RGB method and the HSV method will be described as color display methods. RGB method is 3 of light
A method of displaying a color with a combination of values of 0 to 255 (maximum brightness of each color) for each of the primary colors R (red), G (green), and B (blue) (when each color has no brightness) Is. For example, if all RGB are designated as 0, they are displayed in black, and if all are designated as 255, they are displayed in white. Red is R: 2
55, G: 0. B: 0, green is R: 0, G: 255. B:
0, blue is R: 0, G: 0. B: Displayed at 255 etc.
The HSV method uses the hue (Hue) and saturation (Saturat).
ion), it is intended to display a color lightness (Value), hue display colors circulation at 360 stages of 0 to 359. That is, red (0) -orange (30) -yellow (60) -yellow green (90) -green (120) -blue green (150) -cyan (1
80) -sky blue (210) -blue (240) -purple (270) -magenta (300) -purple (330) -red (0). Saturation (saturation) is 0 (= achromatic color) to 10
0 ( pure color: maximum saturation of each hue) increases the hue. When the lightness is 0 (= black) to 100 ( pure color: lightness indicating the maximum saturation of each hue), the tint becomes bright.

The representative eight colors are displayed by the RGB method and the HSV method as follows.

The above-mentioned colors, including allowable values, can be displayed in the following range when displayed by the HSV method.

Further, a method of using a processed thread in which a metal is vapor-deposited on the surface of a fiber to be used, or, as seen in JP-A-7-42070, an iridescent fabric using glass beads or an inorganic fluorescent substance as a coloring agent. The production method cannot be put to practical use because the texture of the woven fabric is hard and deteriorates, and there are problems in friction and abrasion durability.

Further, the method of obtaining an iridescent woven fabric by combining the interference coloring fiber and the natural fiber, the chemical fiber or the mixed fiber of the natural fiber and the chemical fiber, which is disclosed in JP-A-11-107110, is more than the conventional method. However, it is a method of expressing an iridescent color by utilizing the interference color expression ability, and the color of the resulting fabric also exhibits a mysterious iridescent color and is epoch- making, but the method for producing the interference coloring fiber is However, it requires high manufacturing technology and equipment, and the cost is high, and there is a problem in widespread market development as a general-purpose fiber product. Also, in order to develop an interference color, a sufficiently high birefringence difference is achieved in combination with a general-purpose fiber forming polymer. However, there is no general-purpose polymer capable of forming a fiber having sufficiently high heat resistance to ensure the heat resistance, and the resulting interference-coloring fiber is inferior in heat resistance, and thus the resulting woven fabric is inferior in heat resistance.

The present invention solves these conventional problems and provides a woven fabric excellent in mystery and excellent in a mysterious color based on a general-purpose technique having high productivity.

3. Dyeing to a warp or weft constituting a woven fabric, or to both of them, in a different color having an atypical cross section of a shape capable of reflecting, scattering, and diffusing light that has optical anisotropy with respect to the incident angle of light. By using a bundle of multifilament yarns prepared as described above, a plurality of the different color dyeing and irregular cross-section multifilament yarns are arranged in parallel on the surface of the texture point of the fabric to form a fabric. It is possible to obtain a woven fabric having a color.

4. On the texture point surface of the woven fabric, a woven fabric having a constitutional structure in which multifilament yarns having an atypical cross section are arranged in parallel, first, after weaving a woven fabric of the relevant tissue using an undyed atypical cross-section multifilament yarn having metachromaticity By dyeing with each of the dyes capable of being dyed, a woven fabric exhibiting an iridescent color can be obtained.

[0022] and, in addition to the above-mentioned basic configuration requirements, Tamamushi

An asymmetrical multifilament yarn having a different cross-sectional shape is arranged in parallel and woven to form a fabric having an iridescent color.

Further, in addition to the above constituent elements,
6. A multifilament yarn having two atypical cross-sections which are arranged in parallel on the surface of the weave to form a woven fabric, 7. A fabric having an iridescent color, which has the same monofilament denier and substantially the same total denier, and which constitutes a woven fabric with a modified cross-section multifilament yarn, and The total denier of the single fiber denier is different constitute a fabric exhibiting a Tamamushi-like colors to constitute a fabric by substantially the same cross-section multifilament yarn. However, the above woven fabric defines one that exhibits a more effective iridescent color, does not limit the present invention in any way, and if it satisfies the basic configuration defined in claim 1, Weave with an iridescent color
Not to be excluded as an object.

The necessity for achieving the purpose of each constituent of the present invention and the specific manufacturing method will be described in detail below. The present invention provides (1) as a means for producing a woven fabric having an iridescent color, a texture angle that has been used for a long time has two different-colored fibers arranged in parallel on the surface of the woven fabric to form a woven fabric. In addition to the means for producing a woven fabric that imparts an iridescent color based on the difference in color incident on the eye, (2) spun yarn or multifilament dyed in a different color
At the texture point of the fabric that has an iridescent color composed of yarn
The two threads of the woven warp or weft are arranged in parallel.
Of the two yarns
The two colors used in the set are not in a complementary color relationship with each other and
The difference is 60 to 120, and the combination is based on the HSV method.
A saturation of 50 to 100 and a brightness of 80 to 100
It is necessary to have . That is, if the color tone expressed by a combination of colors of spun yarns or multifilaments dyed in different colors constituting the woven fabric (particularly, a combination of spun yarns or filaments arranged in parallel at the texture points of the woven fabric) is low, the saturation is low. A brilliant color fabric cannot be obtained, and a dull color tone is obtained, and if the lightness is low, only a dark-feeling fabric can be obtained. If the hues of the spun yarns or filaments that make up the woven fabric are not so large (so-called similar colors), the woven fabric will have a poor color change.

Specifically, the combination of hues of the spun yarns or filaments arranged in parallel at the composition points of the woven fabric is such that the hues of similar colors such as red / magenta and blue / cyan are less contrasted. If it is composed of threads or filaments, it will be a woven fabric with little color change, red / green, blue / green,
A combination of red, blue, etc. is not preferable because the brightness is lowered and the resulting fabric feels dark. Furthermore, since the combination of red / cyan, green / magenta, blue / yellow, white / black, etc. has a complementary color relationship, the color tone of the fabric becomes gray.

On the other hand, in the combinations of cyan / yellow, cyan / magenta, yellow / magenta, and red / yellow, the saturation is slightly reduced, but the brightness is not reduced. Woven fabrics woven by arranging them in parallel on the surface of the fabric texture point using spun yarns or filaments with a combination of colors such as green / yellow, green / cyan, blue / magenta, etc., have excellent brightness and saturation. It is possible to provide a fabric with a high iridescent color.

For example, when the two colors used for the warp are combined as follows, the mixed color is determined by the RGB method and the HS method.
The numerical values displayed by the V method are as follows, and the numerical values of the various hue combinations described above are as follows.

In addition to the above-mentioned structure, in order to solve the problem that the mysterious and attractive iridescent color cannot be expressed, the light has an optical anisotropy with respect to the incident angle of light and is reflected / scattered.・ By using a plurality of atypical cross-section multifilaments having atypical cross-sections that can be diffused and forming a woven fabric having a texture structure satisfying the constituent requirement of (1) above, it is possible to form a woven fabric with a conventional woven structure depending on the angle of view. In addition to the function of making a difference in the color of light incident on the surface and exhibiting an iridescent color, the textile constituent fibers themselves have optical anisotropy and reflect / scatter / diffuse the light with respect to the incident angle of light, which results in mysteriousness. It is possible to give the fabric a certain iridescent color.

The first constituent feature of the present invention, namely, a method for forming a woven fabric by combining fibers of different colors in order to obtain a woven bead-like colored woven fabric, in particular, an iridescent woven fabric in which the different-colored fibers are arranged in parallel on the surface of the texture point of the woven fabric. The most basic and simple woven structure form of the woven fabric that satisfies the constitutional requirements for the production of colored woven fabric is a woven fabric having a plain weave structure as shown in FIG. 1, in which the warp yarns A are two warp yarns A- of different colors. It consists of 1, A-2 and this 2
The warp threads of the book are arranged in parallel on the surface of the texture point of the fabric,
A woven fabric having a plain weave structure is formed by the weft yarns B having different colors for both -1 and A-2.

As shown in FIG. 1 and FIG. 2 of the aa 'sectional structure diagram of the woven fabric, the iridescent-like color development mechanism in such a woven fabric is seen from the vertical direction of the upper surface of the woven fabric when viewed from the line of sight a. A mixed color of the colors of the warp yarns A-1, A-2 and the weft yarn B is sensed and recognized, but has a tilt angle perpendicular to the warp direction of the woven fabric and oblique to the plane of the woven fabric. When viewed from the line-of-sight directions b1 and b2, as the inclination angle of the line of sight with respect to the fabric plane becomes smaller, the warp yarn A
A-1 from mixed color of -1, A-2 to single color of warp A-1
In the direction of the line of sight B, from the mixed color of the warp yarns A-1 and A-2 to the single color of the warp yarn A-2, A-
The two colors are strongly recognized.

Further, as shown in FIG. 1 and FIG. 3 of the bb 'sectional view of the woven fabric, a line of sight having a slanting angle perpendicular to the weft direction constituting the woven fabric and oblique to the plane of the woven fabric. When viewed in the directions c1 and c2, the color of the weft B is recognized more strongly, and in the fabric having such a configuration, the color of the fabric is recognized differently depending on the viewing direction and the line-of-sight angle.

Further, a weft B in which two wefts B-1 and B-2 of different colors are arranged in parallel on the texture point surface of the woven fabric, and the weft B-
1 and B-2 and one warp yarn A of a different color, a woven fabric can be formed by the same mechanism as shown in FIG. 4 and FIG. 5 of the bb ′ sectional structure diagram of the woven fabric. When viewed from the line-of-sight directions C1 and C2 which are perpendicular to the direction of the wefts and have a slant angle of inclination with respect to the fabric plane, the angle of inclination of the line of sight with the fabric plane is small with respect to the fabric plane. Indeed, in the line-of-sight direction C1, the color of B-1 from the mixed color of the wefts B-1 and B-2 to the single color of the weft B-1 is strongly recognized, and in the line-of-sight direction C2, the weft B-1, It is possible to obtain a woven fabric which strongly recognizes the color of B-2 from the mixed color of B-2 to the single color of weft B-2.

This is the iridescent color expression mechanism of the iridescent color woven fabric due to the main constitutional requirements. This means uses two warps of different colors in which the woven fabric structure is arranged in parallel on the woven fabric surface.
Even if a woven fabric is made up, or even if a woven fabric is made up of two differently colored wefts arranged in parallel on the surface point of the woven fabric, or if the weave structure is changed to twill weave, satin weave, etc.
In addition, even if the single yarn denier (fineness) of the fabric constituent fibers is changed,
To form a woven fabric by using two different-colored fibers and arranging the different-colored fabric-constituting fibers in parallel on the texture point surface of the woven fabric,
As long as they do not deviate from the constitutional requirements for the production of the iridescent color woven fabric, even if the state and degree of the effect of the iridescent color development may be different, a woven fabric having an iridescent color is obtained.

However, in the method for satisfying the constitutional requirements for the production of an iridescent colored woven fabric using such existing fibers, the single yarn denier of the woven fabric constituting fibers, the number of fibers of different colors and arranged in parallel, Even if the weaving structure is variously modified, the woven fabric condition changing means alone has a limit to the extent that the iridescent color expression effect has some variation, and the purpose is only a relatively monotonous color effect. It does not reach the mysterious iridescent color effect.

Therefore, in order to impart a more mysterious beetle-like color effect, the fiber cross-section is modified due to the development of the synthetic fiber manufacturing technology, so that the light has an optical anisotropy depending on the incident angle of light and is reflected. Focusing on the fact that irregularly-shaped cross-section yarns that scatter and diffuse can be produced, in order to express a mysterious beetle-like color effect that has hitherto been unachievable, in addition to the constituent requirements of the present invention, Either or both of them have an irregular cross-section of a shape capable of reflecting, scattering, and diffusing light that has optical anisotropy with respect to the incident angle of light.
Using multiple multifilament yarns dyed in different colors to form a woven fabric specified in the first constituent requirement, and combining the second constituent requirements to solve the problem and create a woven textile with a mysterious iridescent color. Obtainable.

In the present invention, the irregular cross-section yarn having optical anisotropy and capable of reflecting, scattering, and diffusing has a triangular cross-section (so-called trilobal), Y-shaped cross section, modified Y-shaped cross section, star-shaped cross section. It is an atypical cross-section multifilament that has an optical anisotropy such as a + -type cross-section and a pentagonal cross-section, and has a well-established reputation as an atypical-section yarn having a shape capable of reflecting, scattering, and diffusing.

For example, a triangular cross-section filament yarn has a silk-like appearance and luster, has a well-established reputation in silk-like synthetic fiber production, and is a cross-sectional shape that is frequently used. In order to develop a desired iridescent color, a woven fabric having a desired iridescent color can be obtained by selecting a cross-sectional shape and a modified cross-sectional yarn having a single yarn denier that have the most desirable effect.

As the multi-filament yarn of different color / atypical cross section for forming the woven fabric, even if a woven fabric is formed by using a multi-filament yarn of a different cross section previously dyed with a different color, first, an undyed heterochromatic dye After the woven fabric is formed using the cross-section multifilament yarn, it may be dyed with the dyeable dye of each modified cross-section multifilament yarn.

[0039]

BEST MODE FOR CARRYING OUT THE INVENTION The technical contents and embodiments of the present invention will be more specifically disclosed below based on Examples. [Example 1] As the warp A, a spun yarn A-2 composed of a 40th cotton single yarn A-1 dyed yellow and a 40th cotton single yarn dyed magenta was used, and a weft B was made of a 30th cotton single yarn. Using spun yarn dyed blue, warp A is A-1 (yellow) A-2
Adjacent and repeated with a combination of (magenta), A-1, A-
2, A-1, A-2, A-1, A-2. The warp is arranged so that A-1 and A-2 are arranged in parallel on the surface of the texture points shown in FIG. The constituent fabrics were woven. The obtained woven fabric has a purple color when viewed from the upper side in the vertical direction of the woven fabric, but shows an elegant iridescent-like color with predominantly blue, magenta, and yellow tones depending on the viewing angle. Since has a curved surface and a bulge instead of a flat surface, it was possible to obtain an extremely mysterious item that was very mysterious in color, without inevitably changing the line-of-sight angle.

Example 2 Warp A was dyed blue 40
Using count worsted single yarn, weft yarn B is 30 count worsted single yarn spun yarn B-1 which is dyeable with disperse dye, and 3 which is dyeable with cationic dye.
Using No. 0 worsted single yarn B-2 and a normal loom in a combination of B-1 and B-2 pairs, with the texture point surface shown in FIG.
Wefts B-1 and B-2 are arranged side by side to weave a fabric having a plain weave structure with the warp A, dyed with a yellow disperse dye and a magenta cationic dye, and the weft A is blue and the weft B is Are adjacent and repeated with a combination of B-1 (yellow) and B-2 (magenta), and B-1, B-2, B-1, and B-
2, B-1, B-2, ... Repeatedly, a plain weave fabric having the design shown in FIG. 4 was obtained. Although this woven fabric has a purple color when viewed from the upper surface in the vertical direction of the woven fabric, it was possible to obtain a very mysterious product like an iridescent bead as in Example 1.

0 and stained green and yellow 72d. / 24f (single yarn denier: 3d.) Polyethylene terephthalate triangular cross-section multifilament yarn A-1, A-
2 and 72d. / 24f (single yarn denier:
3d. ), A multifilament yarn made of polyethylene terephthalate having a normal circular cross-section dyed blue and having a saturation and lightness of 100) is used.
Repeatedly adjoining with a combination of 1 (yellow) and A-2 (green),
A-1, A-2, A-1, A-2, A-1, A-2 ...
The warp yarns are arranged so as to be arranged, and A-1 and A-2 are arranged in parallel on the surface of the texture points shown in FIG. 1 using an air jet loom, and a plain weave fabric is formed with the weft yarn B. The fabric was woven. The obtained woven fabric has a bluish-green color when viewed from the upper side in the vertical direction of the woven fabric, but depending on the viewing angle, it shows an elegant iridescent-like color of green, yellow, and blue, and was produced using such a woven fabric. Since the product is not flat but has a curved surface and a bulge, it is inevitable to obtain a very mysterious, iridescent-like product without consciously changing the line-of-sight angle.

Example 4 The warp A has a saturation and lightness of 100 and has a normal circular cross section dyed with cyan 72d. / 24 f (single yarn denier: 3 d.), A multifilament yarn made of acid dye-dyeable polyethylene terephthalate, and weft yarn 72 d. / 24f (single yarn denier: 3d.) Triangular cross-section multi-filament yarn B-1 made of disperse dye dyeable polyethylene terephthalate, and triangular cross-section multi-filament yarn bundle B- 2 made of cationic dye dyeable polyethylene terephthalate. And, B-1,

Then, repeatedly, B-1, B-2, B-1, B-
2, B-1, B-2, ... Repeatedly, a plain weave fabric having the design shown in FIG. 4 was obtained. Although this woven fabric is purple when viewed from the upper side in the vertical direction of the woven fabric, it was possible to obtain a very mysterious product having an iridescent color as in Example 1.

It can be provided by using general-purpose synthetic fibers that can be easily produced, without using the functional composite fibers. Furthermore, for the iridescent-like color effect, the cross-sectional shape of single-filament denier or the cross-sectional shape of the irregular cross-section multi-filament yarn that has optical anisotropy and reflects, scatters, and diffuses the incident light to be arranged in parallel on the texture point surface of the fabric is selected. As a result, it also has the selectivity to tailor the fabric to the desired color effect.
