BACKGROUND OF THE INVENTION
The present invention relates to a multi-color spots dyed fabric 帛 having a three-dimensional feeling and luxury.
[0002]
[Prior art]
Conventionally, natural fibers have been considered to have a natural feeling in dyed products due to the difference in minute dyed feet at the single fiber level, unlike synthetic fibers. Furthermore, for wool and other fabrics, top-dyed techniques are often used in which 10 or more colors of pre-dyed cotton are mixed and knitted. In addition, synthetic fibers that have been colored in a color mix with fine color spots scattered have been proposed for the purpose of natural color unevenness or new visual effects. However, in order to give shades of color unevenness to synthetic fiber fabrics that are originally dyed uniformly or to create spots with distinct color differences or shades of color difference, it is necessary to take the following method. That is,
(1) A method in which a spun yarn obtained by blending fibers separately dyed at the cotton stage in advance and a yarn dyed separately at the yarn stage are mixed and knitted to form a fabric. (2) Dyeability A method of knitting and knitting fabrics mixed with different fibers (3) A method of dyeing (3) A method of printing spot patterns by the number of colors by roll printing or screen printing (4) Fabricating particles containing dyes on the fabric For example, a method of coloring by applying.
[0003]
However, in the method (1), in order to obtain a fabric having the desired color tone, preparations must be made from the stage of cotton dyeing, and a very long process must be passed. In addition, since the color mix that can be produced is a partial color change in units of yarn if it is dyed by yarn, the size of the color range that appears on the surface of the fabric is one yarn dyed with a single color. In the case of partial dyeing, regular patterns are likely to occur due to the relationship between the dyeing length of the yarn and the pitch of the woven fabric, and the minimum spots are also limited to yarn width × knitting pitch. In the case of cotton dyeing, the size of the color range is basically limited to one single fiber and has directionality depending on the woven structure. In the method (2), although the dyeing can be performed at the post-processing stage, the size restriction is the same as in (1). Furthermore, regarding the color tone, since combinations of dyes and materials that can be dyed in different colors are limited, the combinations of colors that can be used in only a few colors are limited. The printing method (3) is laborious and expensive to produce roll engraving patterns and screen molds that determine the density and size of the spots, so the degree of freedom is low and the number of spots is large. And we have to repeat the printing for that number of sheets. And since the size of the obtained spots is limited in engraving on screen meshes and rolls, it is impossible to produce very fine ones, and regularity and periodicity occur in the distribution of color spots, and the quality of the fabric as a color mix. There is a problem that damages. Regarding the method (4), various methods have been proposed for the production of dye-containing particles. After the dye is coarsely grained, the dispersion is applied by means of screen printing, coating, dipping, or the like. This method can be easily applied by post-processing, and can give particles of any color in a single process. Since it is possible, there is an advantage that arbitrary multicolor spot dyeing can be easily performed.
[0004]
However, in these methods, water-soluble polymers, activators and dyes are prepared as described in JP-B-55-42194, JP-B-40-22032, and JP-B-48-2276. In the case of a technique in which the coagulated material is once filtered, dried, pulverized and sieved before use, a uniform particle size can be obtained arbitrarily, and the stability is high, but the process becomes considerably complicated. There is a basic problem that it is difficult to take immediate action because it has a large energy loss for drying wet mud and is not suitable for a small variety of products. Dye-containing particles can be prepared in advance, but in that case, since the color and the size of the particles are fixed, there is a problem that the size of the spots cannot be arbitrarily taken.
[0005]
As described above, in the past, regularity and periodicity are generated by the woven structure or screen, or the size of the spots is often limited even when it is not, and various multicolored spots are dyed by various fabrics. That was difficult. In addition, even when various designs are made with the aim of producing high-quality dyed fabrics, it gives the impression that the spots are too conspicuous or simply dusty, and the surface of the prefabricated fabric has a woven structure. There were many states such as giving a rough image by killing the feeling, and a natural and elegant spotted dyed fabric could not be obtained. Therefore, there are many similar qualities in the multi-colored spot-dyed fabric, which is conventionally called a color mix tone, and it has been difficult to easily design a material that is novel and satisfactory in terms of quality such as a high-class feeling and a natural feeling.
[0006]
[Problems to be Solved by the Invention]
According to the present invention, in a so-called color mix-finished fabric in which two or more colors are mixed in a minute area, a dyed fabric having a natural feeling and having a spot dyeing design that improves the three-dimensional feeling and texture of the fabric. Can be provided.
[0007]
[Means for Solving the Problems]
The multicolor spotted dyed fabric of the present invention has the following constitution in order to solve the above problems. That is, multi-color punctate staining fabric of the present invention, containing 2 or more colors region, a dyed fabric is knitted woven structure and dispersion relation Classification, in the individual color area, the other colors Assuming a maximum circle that does not, the diameter of the circle is within twice the average yarn diameter on the fabric surface, and for at least one color region, the maximum diameter of the circle is the average yarn on the fabric surface. It is a multicolor spotted dyed fabric characterized in that it is 1/10 or more of the diameter, and the dyeing area by the dye-containing particles is 40% or more of the fabric surface in total for all colors .
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail.
[0011]
The feature of the multicolor spotted dyed fabric of the present invention is that the size of the minute color spots is in harmony with the shadows due to the irregularities inherent in the fabric surface. As a result, a natural color mix is obtained, and at the same time, the three-dimensionality and texture of the material are not impaired. When there are fine color spots on the fabric, the surface feeling often changes considerably compared to the plain color due to visual effects. In particular, the three-dimensional feeling and texture due to the surface structure inherent to the fabric are important elements of the quality of the dyed product, but if the color spots applied do not match it, the quality is adversely affected. . And the delicate surface feeling of the fabric is that the shading produced by the yarn on the fabric surface is an important factor, so only when the yarn diameter on the fabric surface and the size of the color spots are appropriate. A high-quality multicolor spotted dyed fabric can be obtained by a synergistic effect.
[0012]
In addition, since the color spots of the multicolored spot-dyed fabric of the present invention have substantially no periodicity and regularity, there is no particular portion that gets a lot of attention or a pattern is raised. Has a classy appearance.
[0013]
In the present invention, the multicolor spotted dyed fabric refers to a fabric in which two or more color spots are spotted on the surface of the fabric.
[0014]
In this case, even if the fabric is dyed to the ground color and has spots of other colors on it, the ground color part remains or there is a white part that is not dyed at all. Consider color or white as one color on the fabric, respectively.
[0015]
The shape and size of the region formed from the color spots of each color on the fabric may be uniform, but if there is some variation, there is a more natural feeling and a higher-class feeling increases. Moreover, even if the color spots have the same shape, when the density is increased and the color spots of the same color overlap or contact with each other on the fabric, as shown in FIG. A variety of complicated shapes.
[0016]
In such a case, it is difficult to specify the size of the color spot. However, in the present invention, due to the relationship between human vision and the quality of the actual multicolored spotted dyed fabric, no matter what the shape of each color region is, other colors are mixed in that region. If the non-existing range is a size within a certain standard with respect to the yarn width on the fabric, a fabric having a high quality appearance can be obtained.
[0017]
As shown in FIG. 1, the area occupied by each color spot on the fabric in the present invention is a color in which a color difference is recognized when the fabric is macroscopically observed by a microscope, enlarged by a video, a photograph, a color scanner or the like. Each number is a part that can be regarded as the same color. Assuming the largest circle that is inscribed in the boundary of the region and does not contain other colors, as shown in A in FIG. 1, for each of these regions, no matter how wide the color region is, it is recognized by the naked eye as a single color. The area of the color to be obtained can be approximated to the size of the inscribed circle A. If the color spots are uniformly dispersed, it is not necessary to strictly measure all the color areas on the fabric, and a part of the color spots may be observed. In rare cases, even if there is a large color area, it can be observed as a defect or ignored for the overall quality. Such extraction of the color region and specification of the size can be performed with the naked eye. However, when the color difference between the color spots is clear, it is more efficient to use image processing by a computer.
[0018]
In the present invention, the yarn diameter means the thickness of the yarn appearing on the surface of the fabric among the yarns constituting the fabric. Warp and weft yarns have different thicknesses on the fabric surface, and some fabrics use yarns with different thicknesses. In that case, the thickness of the yarn that determines the unevenness of the fabric surface is particularly important. Okay, generally the thick thread on the surface.
[0019]
In the present invention, the diameter of the circle assumed in each of the above-described individual regions is set to be within twice the yarn diameter. If the yarn diameter exceeds twice the yarn diameter, it will not be in harmony with the shadows caused by the surface irregularities of the fabric itself, and it will be too conspicuous. In addition, at least one color has a diameter of 1/10 or more of the yarn diameter. When the thread diameter is smaller than 1/10, the spots recognized by the naked eye are too small to be buried in the unevenness of the fabric and to increase the synergistic effect on the material texture and stereoscopic effect of the fabric. There is a problem that cannot be done. More preferably, when each color is in a range of less than 1 time, the yarn diameter that forms the unevenness is not exceeded, so that it is integrated with the unevenness constituted by the yarn, and the three-dimensionality of the fabric is not impaired, and a more luxurious feeling is obtained. It is preferable.
[0020]
When the weaving density of the fabric is low and the gap between the yarns is wide, the color area larger than the yarn diameter is often divided by the gaps across a plurality of yarns, but unless other colors are sandwiched. In this case, it is considered that the same color is continuous.
[0021]
Regarding the relationship between the thread diameter and the color area, when the cloth is enlarged and observed, whether or not the thread appearing on the surface is completely included in the thread width direction is observed in each color spot. Can be roughly distinguished.
[0022]
In the present invention, the density of color spots is also related to the quality of the fabric. In the present invention, among the colors on the fabric, it is preferable that at least one color region of the darkest color is always present in a circle within 5 times the average yarn diameter of the fabric surface, and the spots are If it is more sparse, the color spots on the fabric may be too conspicuous and impair the natural feeling, and in some cases, it may give the impression of being stained. It is more preferable that one or more color spots are present inside a circle having a diameter of 3 times or less than the yarn diameter, which gives a more uniform impression.
[0023]
According to the present invention, any combination of colors on the fabric can be taken, and even if it is multi-colored, it is elegant, so more complicated expression is possible, but color spots of relatively close hue and density are possible. The fabric mixed with the center of the surface has better surface roughness and color familiarity, and can be of higher quality.
[0024]
The target fabric is not particularly limited for both the material and the woven structure.
There are many fabrics such as crepe that have large unevenness due to the structure rather than the unevenness due to the thread, but it is better that the fine shadow due to the thread matches the color spots than the large shadow. This technique can be used.
[0025]
Next, the manufacturing method of the multicolor spot-like dyeing | staining cloth of this invention is demonstrated.
[0026]
The multicolored spotted fabric of the present invention gives dye-containing particles to the fabric at a low particle density in advance so that the color spots do not overlap and develops color, and the size of the color spots dyed on the fabric is measured by magnifying observation. In addition, the minor axis of the particle is within twice the yarn diameter measured by observing the cloth surface to be applied with a magnifying glass or the like, and at least one-tenth or more for at least one color. The dye-containing particles in the range are used for dyeing.
[0027]
When dye-containing particles having a size in this range are used, even when the colored particles are applied to the fabric at a high density, even if the color spots overlap and continue in an irregular shape, basically other color regions in the color region. Since the range where the colors are not mixed is close to the area dyed by the single particles of the dye-containing particles of that color, the multicolor spotted dyed fabric of the present invention can be obtained.
[0028]
In addition, if there are too few color spots on the fabric dyed by the dye-containing particles, the color spots will be sparse, and conversely, the ground color or unstained white area will be widened. because not to do dyeing fabric, dyeing area by the dye-containing particles, in the total colors, adjust the density of the dye-containing particles so that more than 40% of the fabric surface.
[0029]
The preparation method of the dye-containing particles is preferably a preparation method in which the particle size can be changed easily and arbitrarily because it is necessary to take an appropriate particle size depending on the fabric.
[0030]
Such a preparation method is not particularly limited. For example, by adding an aqueous solution of a polyanionic polymer containing a dye and an emulsified water-insoluble liquid to the polycation aqueous solution, A method of forming a dye-containing coagulum by a complex can be used. By changing the stirring speed, the particle size can be arbitrarily changed. In such a method, the particle diameter is not uniform and can vary to some extent, but rather contributes to the improvement of the natural and high-quality feeling of the fabric. However, if particles that are significantly larger than the range of the present invention are mixed even if they are slightly, the portion tends to become a conspicuous defect on the fabric, and therefore, it is removed beforehand by a method such as filtration or centrifugation before being applied to the fabric. It is desirable to do.
[0031]
Also, the material of the fabric is not particularly limited as long as the dye used acts, and various materials can be used, and the structure can also be used according to the use such as knitted fabric and nonwoven fabric.
[0032]
Hereinafter, the present invention will be described in more detail with reference to examples.
[0033]
【Example】
[Example 1 and Comparative Example 1]
The following dye, polyanion polymer and water-insoluble liquid were mixed with a surfactant and water, and 100 parts were used as a polyanion liquid containing an oil-in-water emulsion.
[0034]
Dianix Yellow AN-P 0.5% by weight
Dianix Red BP (Dianix Red BP) 0.3 wt%
Dianix Blue KRN-P 0.1% by weight
(The above, manufactured by Mitsubishi Chemical Corporation, disperse dye)
Snow Algin M 1.5% by weight
(Fuji Chemical Co., Ltd., sodium alginate)
Mineral Spirit A 40% by weight
(Nippon Oil Co., Ltd., 4th class 2nd class petroleum)
Nonipol 95 1% by weight
(Sanyo Chemical Industries, Ltd., surfactant)
56.6% by weight of water
Moreover, 150 parts of polyallylamine hydrochloride was used as a 4% by weight aqueous solution. While dropping the above polyanion aqueous solution into this aqueous solution, the solution was stirred with a commercially available homomixer to obtain a liquid in which tea-based dye-containing particles having a minor axis of 240 μm or less were dispersed in water. Similarly, a purple particle liquid having the following contents and the same composition of the other components was prepared. However, the average minor axis of the particles was set to 320 μm by slowing the stirring speed.
[0035]
Dianix Yellow AN-P 0.1% by weight
Dianix Red BP (Dianix Red BP) 0.5% by weight
Dianix Blue KRN-P 0.3% by weight
The particle liquid was subjected to suction filtration using a 60-mesh sieve.
[0036]
In order to examine the size of the dyed particles on the respective fabrics in advance, the above two-color particle liquids were prepared by using 50 parts of Tantel Gum F 10 wt% liquid (manufactured by Dainippon Pharmaceutical Co., Ltd.) with respect to 5 parts of the particle liquid. After mixing, applying to polyester broad, and passing through a color washing step, a fabric having sparsely dispersed particles was obtained. When the size of the stained color spots was observed with a microscope, the minor axis of the brown and purple color spots was approximately 240 μm and 320 μm or less. Two types of the particle liquids were mixed at a ratio of 1: 1 to obtain a liquid containing two-color particles.
[0037]
To 30 parts of this particle solution, 50 parts of 18% by weight tantel gum F (Dainippon Pharmaceutical Co., Ltd.) and 20 parts of water were mixed as a paste to obtain coating paste (1) in which the dye particles were dispersed.
[0038]
When this paste was observed with a microscope, it was in a state in which two-color dye-containing particles were dispersed in the paste.
[0039]
Further, 60 parts of tantel gum and 30 parts of water were mixed with 10 parts of the same particle liquid to obtain coating paste (2) having different dye-containing particle contents.
[0040]
Next, the coating paste (1) was coated on each of polyester fabrics having a yarn diameter different from 180 μm to 480 μm using a 40 mesh screen to obtain samples A, B, D, and E. Sample C was applied to the same fabric as sample B using coating paste (2). Sample F was prepared as Comparative Example 1 by applying a paste (1) to a polyester fabric having a yarn diameter of 150 μm. The applied amount was about 120 g / m ² .
[0041]
After the fabric was dried, a color mixed fabric was obtained through a coloring process using a normal HT steamer, water washing, and RC washing process.
[0042]
As a result of observing these fabrics, the areas dyed with the dye-containing particles of glue (1) were in a state of sticking and continuous in a larger range than the original spots, but within the same color area. Assuming a single color circle that does not contain other colors, its diameter was generally less than 320 μm. Similarly, in the white region which is the ground color, the dyeing area on the fabric without including other colors was about 70% in total for the two colors.
[0043]
As a result of evaluating the quality of each fabric, samples A, B, C, D, and E in which the diameter of the circle is within the scope of the present invention with respect to the yarn diameter of the fabric surface give the fabric a three-dimensional feeling. In contrast to the natural quality, the sample F, which is out of the present invention as Comparative Example 1, has a slightly over-colored spot with respect to the quality of the fabric, and the surface texture originally possessed by the fabric has been lost. It was in a state. Compared to sample B of the same fabric with glue (1), sample C with glue (2) had sparse color spots and was somewhat conspicuous. When this sample C was observed with a magnifying glass, there were few color spots on the fabric. Therefore, the portion that did not contain purple color spots had an area of a circle with a diameter approximately 6 times or more of the yarn diameter. The dyeing area on the fabric was about 30%. The results are shown in Table 1.
[0044]
[Table 1]

[Example 2 and Comparative Example 2]
In the same manner as in Example 1, a blue-violet fine particle liquid containing the following dye was prepared. However, five types of fine particle liquids having an average major axis of 40 μm to 400 μm were obtained by changing the stirring speed in the mixer.
[0045]
Dyanix Red BP (Dyanix Red BP) 0.4 wt%
Dyanix Blue KRN 1.0% by weight
(The above, manufactured by Mitsubishi Chemical Corporation, disperse dye)
These fine particle liquids were applied as coating paste in the same manner as in Example 1 and applied to two types of fabrics. After normal color development and washing steps, the resulting spotted dyed fabrics were observed. The results are summarized in a table. Among these, in the case of the sample O in which the ratio of the maximum circle that can be assumed in the color region referred to in the present invention and the yarn diameter of the fabric surface is smaller than the range of the present invention, the surface feeling of the material is hardly changed, and the effect of the color mix is improved. Although not seen, samples G, H, I, K, and L had a soft three-dimensional appearance and finished with the most luxurious feeling. Samples J, M, and N were materials that gave a sense of sharpness to the eye. However, Comparative Example Sample P, which has a higher ratio than the present invention, was too rough and too grainy, and had no impression.
[0046]
The results are also shown in Table 1.
[0047]
【The invention's effect】
The present invention relates to a color mix-like dyed fabric in which two or more colors are mixed as minute spots, and is a new and high-quality dyed fabric that has a high-class feeling, a natural feeling, and an enhanced three-dimensional feel of the material.
