Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of dyeing different colors, and more particularly, to a method of dyeing a fabric by at least three colors after one bath.
The present invention relates to a dyeing method for dyeing more than one kind of color, and a fabric dyed by such a dyeing method.

[0002]

2. Description of the Related Art In order to improve the design of fabrics, fabrics of a plurality of colors are sometimes used. However, in the textile industry, dyeing companies, weaving companies, designers, and sales companies are all separated and separated. No product development has been carried out from a total point of view for fiber dyeing. Therefore, when designers and distributors want multi-colored products, conventionally, the yarns constituting the fabric are dyed in a desired color in advance, and the fabric is knitted from a plurality of yarns dyed in a desired color. This forms a multicolored fiber.

[0003] However, such a yarn-dying method is uneconomical because a yarn loss of 5% to 8% is usually caused. For example, a shortage of one kind of color causes a delivery date to be delayed or a color to be lost. Out of balance, dyeing period (1.5 to 2 months required at peak)
Is necessary, there is a delay in delivery, there is a great fear of loss of quotient opportunity, there is a drawback of jumping of other colors, knitting of each color, management of yarn dyed, etc.
The workability was poor, the color could not be changed, the yarn was dyed in advance, and there was a problem due to the difference in the image when the fabric was used.

Conventionally, as a method of dyeing blended and interwoven fibers, dyeing in two colors has been performed. However, the dyes that can be used in the same bath are limited, and dyeing of three or more colors by dyeing after one bath is performed. It is not the fact. For example, Tokuho 7-9
No. 1740 discloses a sportswear fabric which is dyed in a different color. This fabric also dyes a polyester dyeable with a normal pressure cationic dye with a cationic dye and a polyamide fiber with an acidic dye. Is to be dyed.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a fiber (yarn)
Investigate the dyeability of each dye, select a plurality of yarns that will be multicolored in relation to the selected dye, fabricate by knitting or weaving from such yarns, and fabric after dyeing after one bath Is intended to be able to be dyed into three or more colors, and an object of the present invention is to eliminate the disadvantages of the conventional dyeing method.

[0006]

The technical means adopted by the present invention to achieve the above object is at least one selected means.
2 out of a group of fibers corresponding to the dye-dyeing properties of two or more dyes
The above fibers are selected, and the selected fibers include at least two or more kinds of fibers having different dye distribution ratios, and fabrics are made from such fibers, and the dyeing properties of the selected dye and the properties of the fibers for the selected dye are determined. The method is characterized in that the fabric is dyed in a different color after one bath using the dye distribution ratio. Alternatively, two or more dyes having different dye-dyeing properties are selected, and fibers are respectively selected from two or more fiber groups to which the selected two or more dyes are dyed, and a dye is selected from at least one fiber group. At least two types of fibers having different distribution ratios are selected, a fabric is made from the selected fibers, and the fabric is colored in three colors by using the dye-dyeing property of the selected dye and the dye distribution ratio of the fibers. It is characterized by dyeing the above colors after one bath. For example, if the fabric is composed of three types of fibers having different dye distribution ratios for one dye, the fabric can be dyed into three colors by using the dye distribution ratio. Furthermore, if two or more dyes having different dye-dyeing properties and two or more fibers having different dye distribution rates at which the dyes are dyed are selected, multicolor dyeing can be performed using the dye distribution rate and the dye-dyeability. Can do it.

Another technical means adopted by the present invention is to select three or more dyes having different dye-dyeing abilities, and to select one or more from each of three or more fiber groups to which the selected three or more dyes are dyed. Selecting one or more fibers, fabricating the fabric from the selected fibers, and dyeing the fabric into three or more colors after one bath using the dye-dyeing properties of the selected dye. It is. In this case, the fabric can be dyed in three or more colors by utilizing only the dye-dyeing properties. Preferably, at least two or more fibers having a different dye distribution ratio with respect to the selected dye are selected from at least one fiber group. By doing so, it is possible to perform multicolor dyeing using the dye-dyeing property and the dye distribution ratio.

The term “dyeing” refers to a phenomenon in which a dye is selectively absorbed by immersing a fiber in a dye solution and treating the fiber. In the present specification, “dye-dyeability” refers to a certain dye. Means the property of the dye that only dyes specific fibers. Then, the fibers constituting the fabric are selected from a group of fibers in which the selected dye is dyed.

The dye preferably comprises a dye selected from cationic dyes, acid dyes, direct dyes, disperse dyes, reactive dyes and acid mordant dyes.
Directly selected from dyes. Further, at least one selected from a cationic dye, an acid dye, and a direct dye may be used, and a disperse dye, a reactive dye, an acidic mordant dye, and the like may be used in combination.

When a cationic dye is selected, a fiber is selected from a group of fibers corresponding to the cationic dye. Preferably, acrylic fiber, cationic dyeable polyester (CD)
P) is used. When an acid dye is selected, wool, silk, polyamide fiber, or the like is selected, and nylon 6, nylon 66 is preferably selected. If direct dyes are selected, cotton, rayon, cupra, tencel,
Cellulose fibers such as hemp are preferably selected. When the fabric contains acetate, triacetate, or polyester fibers, the fibers can be dyed by suitably selecting a disperse dye. When a reactive dye is selected, cellulose fiber, wool, polyamide fiber and the like are selected. When an acidic mordant dye (chromium dye) is selected, wool, silk, nylon and the like are selected.

In addition, various fibers (yarns) can be dyed with the same type of dye, but have their own dye absorptivity (capacity or amount to absorb the dye of the yarn). ) Also has a unique dye dyeing rate (speed of dye dyeing on the yarn) while being a dyeable fiber.
Since the dye dyeing rate can be considered as one factor that determines the speed at which the yarn adsorbs the dye from the yarn side, in the present specification, the dye (the individual dyes constituting one dye) is used. The ability of the fibers to adsorb dyes (including individual dyes) in relation to the dyes (including dyes) is referred to as the dye distribution of the fibers.

When a plurality of fibers having different dye distribution ratios are dyed by using a dye consisting of one dye, shading can be obtained because the fibers have different forces of pulling (adsorbing) the color. In addition, since a dye is usually formed by mixing a plurality of dyes, for example, when dyeing a fabric made of a plurality of fibers having different dye absorptivity with a violet dye (comprising a red and a blue dye), Depending on the dye distribution of the fibers (determined by the fiber's dye absorption and dye dyeing rate), the fabric can be dyed in multiple colors (eg, reddish blue, bluish red). Of course, the same is true even when a plurality of dyes of the same system (same race) are used. For example, a fabric made of a plurality of fibers having different dye absorptivity is dyed using two kinds of similar dyes (for example, a cationic dye) of blue and yellow, so that the fabric has a plurality of colors (for example, dark green and yellow green) )
Can be dyed.

More specifically, when a dye of one kind (cationic dye) is used for a fabric made of a dyeable polyester of a cationic dye and acrylic, the dye is dyed in two colors because the dye distribution ratio is different. Similarly, high pressure CDP and normal pressure CDP,
If the fabric is made using acrylic, the fabric can be dyed in three colors. Further, when an acid dye is used for a fiber made of nylon 6 and nylon 66, the fiber is dyed in two colors due to a difference in dye distribution ratio. If a direct dye is used in a combination of rayon and cotton, two colors can be dyed. further,
Rayon, cupra, tencel, cotton 3 ~
It becomes four colors. By adding dull yarn and bright yarn to the fabric, it can be dyed in a different color.

The dye used in the present invention is preferably at least two selected from a cationic dye, a direct dye and an acid dye. Hitherto, it has been practiced to dye a cross-woven fiber in two colors by using a cationic dye and an acid dye and an acid dye and a direct dye in the same bath (see Japanese Patent Publication No. Hei 7-91740).

In general, cationic dyes are used in weakly acidic dye baths, acid dyes are dyed in neutral to acidic dye baths, and direct dyes are dyed in neutral to weakly alkaline dye baths, especially cationic dyes. Has the property of being stable on the acidic side and becoming unstable from neutral to the alkaline side. Therefore, it has been considered that it is not possible to make a cationic dye and a direct dye in the same bath in the past, and the cationic dye was actually decomposed and deteriorated.

On the other hand, the applicant has succeeded in selecting a direct dye which can be dyed stably on the acid side, whereby a cationic dye and a direct dye, which have so far been considered impossible, can be used. Succeeded in the same bath. Such direct dyes include, for example, Shivafix (registered trademark) dyes of Ciba Geigy Co., Ltd. However, the direct dye that can be put into the same bath as the cationic dye is not limited to this, and any dye that can be stably dyed on the acidic side may be used. In this case, the pH of the dyeing bath is from neutral to acidic.
About 3 to PH 6.5 is preferable.

Since the cationic dye and the direct dye can be used in the same bath as described above, the types of fibers that can be selected as the fibers constituting the fabric are increased, and the dye distribution ratio to the same type of dye is different. By selecting a plurality of fibers, a multicolor fabric can be provided.

For example, a dye is a cationic dye, a direct dye,
If the fabric is made of an acid dye and the fabric is made of acrylic fiber, normal pressure cationic dyeable polyester, 6 nylon, 66 nylon, rayon, the acrylic fiber and normal pressure cationic dyeable polyester become the cationic dye and 6 nylon And 66 nylon are dyed with acid dye and rayon is dyed with different color by direct dye.
Acrylic fiber and normal pressure cationic dyeable polyester are dyed in different colors, and nylon 6 and nylon 66 are dyed in different colors. As a result, five different colors can be dyed in one bath. Further, if fibers and dyes are selected, it can be dyed in multicolors of about 10 colors.

If such a fabric contains a polyester other than CDP, the polyester is not dyed, so that the original color, for example, white, is expressed as it is, and as a result, a fabric of six colors can be provided. When a disperse dye is used in combination, polyesters other than CDP can be dyed. Furthermore, if polyurethane elastic fiber is used for the cloth, a multi-color sportswear cloth having a stretch function can be obtained, and such cloth can be suitably used for swimwear and the like.

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for selecting a dye by utilizing the dye-dyeing properties of the selected dye or the dye distribution rate of the fiber (determined by the dye-absorption rate of the fiber and the dye-dye rate of the fiber). The dyed fabric is dyed in a different color. Preferably, a large number of yarn types and a large number of dye types are used, and a combination of the two is used to provide a multicolored fiber. .
