Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a 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 production technique of a technique for producing a woven fabric exhibiting an iridescent color, there is known a technique by Yoshikazu Yoshida, already published on January 22, 1938, for inner and outer woven fabrics and manufacturing studies (Maruzen), p.182 to 183. Discloses a chameleon taffeta manufacturing method. That is, "a method of using one color for the warp and two colors for the weft, and weaving the same in the same yarn.
It is also possible to weave one color 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 made to obtain a fabric having a higher quality iridescent color.
In JP-A-9-117764, three or four colors of A, B, C, and (D) are used as one of the warp and the weft constituting the woven fabric, and three or more yarns of the same color are used to exhibit an iridescent color. Surround B, which is an intermediate color between A and C, which is the center of color expression, without being adjacent to each other, the arrangement order of the yarns constituting the fabric is also arranged as A, B, C, (D), and the weave structure is also relative to the fabric surface of B. Floating / sinking ratio = 3 or more, and floating number of B is 1.5 of A, C, (D)
An improved method of obtaining an iridescent fabric by more than doubling is disclosed.

Further, Japanese Patent Application Laid-Open No. Hei 8-60563 discloses that a woven fabric is formed of a warp yarn (preferably natural fiber or spun natural fiber spun yarn) and a weft yarn (preferably silk, regenerated cellulose or synthetic fiber). An improved method of obtaining an iridescent woven fabric with a universal weave structure by dyeing the warp and the weft into different colors is disclosed.

[0005] In addition, a method using a processed yarn in which a metal is vapor-deposited on the surface of a fiber to be used, and a method of retroreflection, which is one of the anisotropic reflection characteristics, as disclosed in JP-A-7-42070. A method for 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. H11-107110 discloses a method of obtaining an iridescent fabric by combining interference coloring fibers with natural fibers, synthetic fibers, or blended fibers of natural fibers and chemical fibers. The present invention differs from the conventional invention in which an iridescent color is imparted by a combination of weaving conditions or a weaving structure of a different color fiber.
This is a method of developing an iridescent color utilizing the interference color developing ability of a composite fiber obtained by alternately laminating five or more layers in a thin layer of 02 to 0.3 μm.

[0007]

However, a chameleon taffeta manufacturing method described in the description of inner and outer fabric structures and manufacturing technology (Maruzen), which is a classic basic technique for manufacturing a fabric having an iridescent color, and Japanese Patent Application Laid-Open No. 49-117774. In the method of giving a beetle-like color based on a fabric construction method by setting an arrangement / arrangement state in a combination of different-color fibers and setting a fabric construction structure as represented by Japanese Patent Application Laid-Open No. H8-60563, etc. Can be applied, but a mysterious iridescent fabric lacking in a sense of quality could not be obtained.

That is, even when weaving a chameleon taffeta simply using three colors having different hues, the three colors are mixed to give a dark and turbid color, or the color change is poor, so that an iridescent fabric is obtained. Can not do.

For example, when weaving a woven fabric using red and magenta for the warp and yellow for the weft, the mixed color has a reddish hue, but since the same color is used, the color change cannot be reduced. Not get. When red and green are used for the warp and blue are used for the weft, the change in color is clear, but the color becomes dark and cloudy.

[0010] Even if two similar colors are used for the warp, the color change is small. For example, in the case of a combination of relatively similar colors such as red and magenta and blue and cyan, the mixed color has a clear color tone and a hue that does not drop in saturation, but the color change must be poor. . Also, in the combination of red and green, blue and green, red and blue, etc., the mixed color becomes dark,
Since the brightness decreases, the woven fabric has a dark atmosphere.

On the other hand, the combination of red and cyan, green and magenta, blue and yellow, white and black, and the like are in an opposite color (complementary color), so that the mixed color becomes gray, and the woven fabric becomes dull. It becomes hue.

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

Here, an RGB method and an HSV method will be described as color display methods. The RGB method uses light 3
A method of displaying a color by a combination of values of each of the primary colors R (red), G (green), and B (blue) (the state of no brightness of each color) to 255 (the maximum brightness of each color) is there. For example, when all RGB are designated as 0, black is displayed, and when all 255 are designated, white is displayed. Red is R: 2
55, G: 0, B: green, R: 0, G: 255. B:
0, blue are R: 0, G: 0. B: Displayed at 255 or the like. The HSV method includes a hue (Hue), a saturation (Satur)
) and lightness (Value) to display a color, and the hue displays color circulation in 360 steps from 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)-magenta (330)-red (0). Saturation (saturation) is 0 (= achromatic) to 10
0 (dark color: maximum saturation of each hue) makes the color deeper. The lightness is from 0 (= black) to 100 (dull color: lightness indicating the maximum saturation of each hue), and the hue becomes bright.

Displaying the representative eight colors by the RGB method and the HSV method is as follows.

However, when displaying colors numerically,
A constant value may not be obtained depending on the measuring method, measuring instrument, and the like. Therefore, the above colors, including the tolerance,
When displayed by the method, colors in the following range can be obtained.

Further, a method using a processed yarn in which metal is vapor-deposited on the surface of a fiber to be used, or an iridescent fabric using glass beads or an inorganic fluorescent substance as a coloring agent as disclosed in JP-A-7-42070 In the production method, the fabric texture is hard and deteriorated, and there is a problem in friction and abrasion durability, so that it cannot be put to practical use.

Furthermore, the method of obtaining an iridescent fabric by combining interference coloring fibers and natural fibers, synthetic fibers or a blend of natural fibers and chemical fibers as disclosed in Japanese Patent Application Laid-Open No. 11-107110 is compared with the conventional method. It is a method of developing an iridescent color utilizing the interference color expression ability, and the color of the obtained fabric also exhibits a mysterious iridescent color, which is revolutionary, but the method of producing the interference coloring fiber is It requires high manufacturing technology and equipment, and is costly. There is a problem in widespread market development as a general-purpose fiber product, and it has a sufficiently high birefringence difference in combination with a general-purpose fiber-forming polymer to develop interference colors. There is no general-purpose polymer capable of forming a fiber having sufficiently high heat resistance that can ensure sufficient heat resistance, and the resulting interference coloring fiber has poor heat resistance, and the resulting woven fabric has poor heat resistance.

The present invention solves these conventional problems and provides a woven fabric excellent in mystery and excellent in iridescent color, which is based on general-purpose technology with high productivity.

1. The two colors used for the warp or weft of the woven fabric dyed in different colors are not complementary to each other, and the combination has a saturation and lightness of 50 to 100, and the contrast of the hue is large. The present invention constitutes a woven fabric having an iridescent color composed of dyed spun yarn or multifilament yarn. 2. Specifically, the warp yarns are cyan and yellow, cyan and magenta,
It is composed of a multifilament yarn having any color of yellow and magenta, green and yellow, green and cyan, blue and magenta, red and yellow, and weft. Further, the weft may be composed of a spun yarn or a multifilament yarn having an arbitrary hue to the cyan and yellow, cyan and magenta, yellow and magenta, green and yellow, green and cyan, blue and magenta, red and yellow, and warp. Good.

3. Dyeing on the warp and / or weft constituting the woven fabric, or both of them, in a different color having an irregular cross section of a shape that has the optical anisotropy with respect to the incident angle of the light and can be reflected, scattered and diffused Using a bundle of multifilament yarns, a plurality of the different-color dyeing and irregular cross-section multifilament yarns are arranged side by side on the texture point surface of the fabric to form a woven fabric, thereby forming a woven fabric. A colored fabric can be obtained.

4. On the texture point surface of the woven fabric, the woven fabric having the constitutional structure in which the multifilament yarns having the irregular cross section are arranged in parallel, first after weaving the woven fabric of the corresponding tissue using the undyed irregular cross section multifilament yarn having a heterochromatic property By dyeing with each dye which can be dyed, a woven fabric having an iridescent color can be obtained.

Further, in addition to the above basic constitutional requirements, a more specific and effective production method for producing a woven fabric exhibiting a beetle-like color, and as a condition, a plurality of woven fabrics arranged in parallel on the texture point surface of the woven fabric 4. The cross-sectional shape of the multifilament yarn having the irregular cross-section of 5. A manufacturing method in which irregular multi-filament yarns having the same cross-sectional shape are arranged in parallel and woven to form a woven fabric having an iridescent color, and An object of the present invention is to provide a manufacturing method in which irregular multi-filament yarns having different cross-sectional shapes are arranged in parallel and woven to form a woven fabric having an iridescent color.

Further, in addition to the above-mentioned constitutional requirements, as a more effective and specific manufacturing method and condition, a multifilament yarn having a plurality of irregular cross sections constituting a woven fabric arranged in parallel on the texture point surface of the woven fabric, 7. 7. A method for producing a woven fabric having an iridescent color in which the woven fabric is constituted by a modified cross-section multifilament yarn having the same single fiber denier and substantially the same total denier, and A method for producing a woven fabric exhibiting an iridescent color in which a woven fabric is constituted by multifilament yarns having different cross-sections of almost the same denier having different single fiber deniers. However,
The above method defines a method for producing a woven fabric exhibiting a more effective iridescent color, and does not limit the present invention in any way, as long as the basic structure defined in claim 1 is satisfied. It is not excluded as a method for producing a woven fabric exhibiting an iridescent color.

In the following, the necessity of achieving each object of the present invention and the specific manufacturing method will be described in detail. The present invention provides (1) as a means for producing a woven fabric exhibiting an iridescent color, by setting a plurality of different-color fibers in parallel on the surface of a woven fabric used for a long time to form a woven fabric. In addition to the means of producing a woven fabric that gives a beetle-like color based on the difference in the color incident on the eyes depending on the viewing angle, (2) the two colors used for the warp or weft of the woven fabric dyed in different colors It is necessary that the combination be composed of a spun yarn or a multifilament yarn dyed in a different color having a chroma and lightness of 50 to 100 and having a large hue contrast, without being in a complementary color relationship. That is, if the color tone expressed by the combination of the colors of the spun yarn or the multifilament dyed in a different color constituting the woven fabric (especially the combination of the spun yarn or the filament arranged in parallel at the texture point of the woven fabric) is low, A clear color tone fabric cannot be obtained, resulting in a dull color tone. Further, if the lightness is low, only a dark fabric can be obtained. In addition, if the hue of the spun yarn or filament constituting the woven fabric is not large (so-called similar colors), the woven fabric will have little change in color.

More specifically, the combination of the hues of the spun yarns or filaments arranged in parallel at the texture points constituting the woven fabric has a small contrast between the hues of similar colors, such as red / magenta and blue / cyan. If it is composed of yarn or filament, it becomes a woven fabric with little change in color, red / green, blue / green,
A combination of red and blue is not preferable because the brightness decreases and the fabric becomes dark. Further, since the combination of red / cyan, green / magenta, blue / yellow, white / black, and the like has a complementary color relationship, the color tone of the fabric becomes gray.

On the other hand, in the combination of cyan / yellow, cyan / magenta, yellow / magenta, and red / yellow, the saturation is slightly reduced, but the brightness is not reduced. Fabrics woven using spun yarns or filaments of a combination of colors such as green / yellow, green / cyan, and blue / magenta and laid in parallel at the surface of the fabric structure point have excellent lightness and saturation. Can be provided.

For example, when the two colors used for the warp are combined as described below, 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 combinations of the above hues are as follows.

In addition to the above configuration, in order to eliminate the difficulty that a mysterious and quaint iridescent color cannot be expressed, the light has an optical anisotropy with respect to the incident angle of light, and is reflected and scattered. By using a plurality of irregular cross-section multifilaments having irregular cross-sections in a shape that can be diffused and forming a woven fabric having a tissue configuration that satisfies the above-mentioned constitutional requirement (1), an eye can be obtained according to an angle viewed by a conventional woven fabric structure. In addition to the function of giving a difference to the color incident on the surface and exhibiting an iridescent color, the woven fabric fibers themselves have optical anisotropy with respect to the incident angle of light, and reflect, scatter, and diffuse the light. A certain iridescent color can be given to the fabric.

The first constitutional requirement in the present invention, that is, a method of forming a woven fabric by combining fibers of different colors in order to obtain a beetle-like colored fabric, in particular, a beetle-like structure in which the different-colored fibers are arranged in parallel on the surface of the texture point of the fabric The most basic and simple woven structure form of the woven fabric that satisfies the constitutional requirements for the production of a colored woven fabric is a woven fabric having a plain woven structure as shown in FIG. 1, A-2, this 2
The warp yarns are arranged side by side on the surface of the texture point of the fabric, and the warp A
Both -1 and A-2 form a woven fabric having a plain weave structure with the wefts B having different colors.

The mechanism of developing a beetle-like color in such a woven fabric is shown in FIG. 1 and FIG. 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 slant angle perpendicular to the warp direction of the fabric and oblique to the plane of the fabric. When viewed from the line of sight directions B1 and B2, the smaller the inclination angle of the line of sight with respect to the plane of the fabric, the smaller the warp A in the line of sight direction B1.
-1 from a mixed color of A-1 and A-2 to a single color of warp A-1
In the line of sight direction B2, from the mixed color of the warps A-1 and A-2 to the single color of the warp A-2.
They come to strongly recognize the two colors.

Also, as shown in FIG. 1 and FIG. 3 showing the bb 'sectional structure diagram of the woven fabric, a line of sight perpendicular to the weft direction of 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 yarn B is more strongly recognized, and in the woven fabric having such a configuration, the color of the woven fabric is recognized differently depending on the viewing direction and the viewing angle.

A weft B in which two different-color wefts B-1 and B-2 are arranged in parallel on the textured surface of the woven fabric;
1 and B-2 and one warp A of a different color, a woven fabric is formed by the same mechanism as shown in FIG. 4 and FIG. When viewed from the line-of-sight directions C1 and C2, which are perpendicular to the weft direction and have a slanting angle with respect to the plane of the fabric, the angle of inclination of the line of sight with the plane of the cloth relative to the plane of the cloth is small In the line-of-sight direction C1, the color of B-1 is strongly recognized from the mixed color of the wefts B-1 and B-2 to the single color of the weft B-1. It is possible to obtain a woven fabric that 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 mechanism of developing the iridescent color of the iridescent color woven fabric according to the main constituent requirements. This means, even if the woven fabric is constituted by a plurality of warp yarns of different colors arranged in parallel on the surface of the fabric texture point and a plurality of weft yarns of different color arranged in parallel on the surface of the fabric texture point, Even if the weaving structure is changed to twill weave, satin weave, or the like, or if the denier (fineness) of the constituent fibers of the woven fabric is changed, a plurality of fibers of different colors are used at the texture point surface of the woven fabric. By arranging the different-color fabric constituent fibers in parallel to constitute the fabric, as long as it does not deviate from the constituent requirements for manufacturing a beetle-like color fabric, the state of the beetle-like color expression effect, even if there is a difference in the degree,
Both give fabrics with iridescent colors.

However, in the method for satisfying the constitutional requirements for the production of an iridescent color woven fabric using the existing fibers, the denier of the yarn constituting the woven fabric, the number of fibers of different colors arranged in parallel for the woven fabric, Even if various measures are taken to change the weaving structure, etc., only the fabric composition condition changing means has a limit to the effect of producing a beetle-like color, with a certain degree of variation. It does not lead to the mysterious iridescent color effect.

Therefore, in order to further impart a mysterious beetle-like color effect, the fiber cross-section is modified according to the development of synthetic fiber production technology. Focusing on the ability to manufacture irregular cross-section yarns that scatter and diffuse, in addition to the constituent requirements of the present invention, in order to develop a mysterious beetle-like color effect that was previously unattainable, the warp or weft of the woven fabric Either or both of them have an irregular cross section of a shape that can reflect, scatter and diffuse light with optical anisotropy with respect to the incident angle of light,
Using a plurality of multifilament yarns dyed in different colors, the fabric specified in the first component is constituted, and the problem is solved by combining the second component to produce a fabric having a mysterious iridescent color. Obtainable.

In the present invention, the irregularly shaped yarn having optical anisotropy and capable of being reflected, scattered, and diffused has a triangular cross section (so-called trilobal), a Y-shaped cross section, a modified Y-shaped cross section, and a star-shaped cross section. This is a multi-filament multi-filament having an optical anisotropy, such as a +, a cross-section and a pentagonal cross section, and having a reputation as a modified cross-section yarn having a shape capable of reflection, scattering and diffusion.

For example, a filament yarn having a triangular cross section has a silky appearance and luster, has a reputation in the production of silk-like synthetic fibers, and has a widely used cross section. In addition, a woven fabric having a desired iridescent color can be obtained by selecting a cross-sectional shape and a single-denier irregular-shaped yarn having the most desirable effect in order to develop a desired iridescent color and producing a woven fabric.

The multi-filament yarn having a different cross section and different cross section forming the woven fabric may be formed by using a multi-filament yarn having a different cross section which has been dyed in a different color in advance. After the woven fabric is formed using the cross-section multifilament yarn, each of the modified cross-section multifilament yarns may be dyed with a dye capable of being dyed.

The constituent fabrics were woven. The obtained woven fabric has a purple color when viewed from the upper surface in the vertical direction of the woven fabric, but exhibits an elegant iridescent color with a predominant color of blue, magenta, and yellow depending on the viewing angle, and is an article produced using such a woven fabric. Since it has a curved surface / bulge instead of a flat surface, it was inevitably possible to obtain an extremely mysterious, rich, iridescent-colored article without consciously changing the viewing angle.

A woven fabric having a plain weave structure having the structure shown in FIG. 4 repeated as 2, B-1, B-2,... Was obtained. The woven fabric has a purple color when viewed from the upper surface in the vertical direction of the woven fabric. However, as in the case of Example 1, a very mysterious article with a rich iridescent color was obtained.

.. Are arranged in parallel with each other, and A-1 and A-2 are arranged in parallel on the surface of the texture point shown in FIG. The fabric was woven. The obtained woven fabric is a blue-green color when viewed from the upper surface in the vertical direction of the woven fabric, but shows an elegant iridescent color with a predominant color of green, yellow, and blue depending on the viewing angle, and was manufactured using such a woven fabric. Since the article has a curved surface and a bulge instead of a flat shape, it was inevitably possible to obtain an extremely mysterious article with a rich iridescent color without consciously changing the viewing angle.
