DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of dyeing a fabric into various color patterns by using an ink jet dyeing method in which a dye is transferred to a floating surface on a water surface, and a dyed fabric dyed by the method. About.

[0002]

2. Description of the Related Art Ink-sinking patterns are formed on the basis of accidental convection, so that they are unique and give a natural impression to a viewer. These two points are features that are not found in artificially designed patterns, and are recognized for their artistry and commercial value. Transferring sumi-shi patterns to fabrics has been practiced since the Edo period. However, the pattern was a monochromatic pattern stained with ink or plant extracts. If a multi-colored sumi-shi pattern can be expressed on fabric, higher artistry and commercial value can be obtained, and various dyeing methods have been tried. However, the conventional techniques have problems in clarity of dyeing, fastness, and weather resistance, and no ink-wash dyeing method capable of freely dyeing various color patterns has been established.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to convert various fabrics into various color patterns having high clarity, fastness, and weather resistance.
Establish a dyeing method that can carry out sumi-shi dyeing that can be dyed freely using simple equipment with simple operations, and can also transfer patterns instantaneously and reliably, and provide dyed fabrics processed by that dyeing method. That is.

[0004]

Means for Solving the Problems To achieve the above object, a method for dyeing a fabric by the ink jet dyeing method according to the present invention comprises the following arrangement. That is, a drug-diluted aqueous solution in which a sizing agent containing a surface inactive component and a thickening component and an auxiliary agent containing a surface active component are mixed is prepared in a water tank.
To this, multicolor dyes are sequentially added, and the water surface is stirred to form a desired pattern. Then, the fabric is immersed in the water surface to transfer the pattern.

[0005] When a dye is added to a dilute aqueous solution of a drug, a process of first dispersing a white or light-colored dye substantially uniformly on the water surface and then sequentially adding multicolored dyes is used. Alternatively, it may contribute to the diffusion control of multicolor dyes and clear dyeing.

[0006] In addition, a natural rubber extract and a seaweed extract may be contained in the paste at an equal ratio, thereby contributing to improvement in the efficiency and accuracy of dyeing.

[0007] The dyed fabric of the present invention is a fabric which is dyed by the above-mentioned dyeing method and a method described in detail below, and particularly includes a sizing agent containing an inactive component and a thickening component, An auxiliary agent containing a surfactant component, and a multi-colored dye are sequentially added to the diluted drug aqueous solution mixed with the agent,
After the water surface is agitated to form a desired pattern, the fabric is immersed in the water surface and the pattern is transferred and dyed.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective explanatory view showing an outline of the staining method of the present invention. The cloth (10) is shown in FIG.
The cords (12) and (12) are connected to both ends thereof via support plates (11) and (11). On the side edge of the fabric (10), a large number of bow-shaped stretching tools (13) composed of bamboo strings and needles are attached. The fabric (10) is stretched flat with the pins by the restoring force of the tensioner (13).

The flattened fabric (10) is shown in FIG.
It is immersed in the water tank (20A) shown in (b) to transfer the pattern floating on the water surface. The water tank (20A) has a two-layer structure in which the dye (40) floats on the surface of a dilute aqueous solution (30) of a chemical agent that assists dyeing.

Next, the cloth (10) on which the pattern has been transferred is dipped in a water tank (20B) shown in FIG. This washing is not an essential step, but contributes to the removal of the extra stain agent (40) and the dilute aqueous solution (30). The water tank (20B) contains ordinary tap water (5
0) is filled.

[0011] The cloth (10) dyed in this way is placed between the struts (23) and (23) shown in FIG.
2) It is stretched through (12) and dried.

In the above-mentioned dyeing step, the present invention adopts the following constitution so that the cloth (10) can be dyed freely into a sumi-run pattern of various colors. FIG. 2 shows an aquarium (2
It is a plane explanatory view which shows the process of adding a multicolor dyeing | staining agent (40) to 0A) one by one, and shaping a water surface, and shaping a desired blackwashing pattern.

[0013] The water tank (20A) is first filled with a dilute aqueous solution (30) of an agent for assisting dyeing. The water depth is 2
About 0 to 40 cm is preferable. The agents include the following sizing agents and auxiliaries.

[0014] The paste contains an interface inactive component and a thickening component in equal proportions. As the surface inactive component, a natural rubber extract, particularly capsicum gum and gum arabic is most suitable. These natural rubbers have an interfacial inerting effect to form a film on the water surface or increase the surface tension.

As the thickening component, a seaweed extract, especially cloth laver, sodium alginate and Amatex are most suitable. These seaweeds are not only easily dissolved in water, but also have a thickening effect of giving water stickiness and maintaining a state.

[0016] Of the natural rubber, wood wax and pine resin are not preferable because they cause contamination of the fabric and cause color bleeding. In addition, starches such as rice flour, potatoes, sweet potatoes, and minerals such as bentonite, talc, porcelain clay and the like are also mentioned as sizing agents, all of which are difficult to dissolve in water, and starches are easily rotted, It is hard to say that it is suitable.

The assistant contains a surfactant. This lowers the strong surface tension of the water to allow the dye to diffuse well on the surface of the water, contributing to the appearance of a white background and sharpening of the pattern. Oil-based auxiliaries are not suitable because they separate from water and are inconvenient for dyeing, and may add odor to the fabric, cause discoloration, or damage fibers.

Here, the dilute aqueous solution (30) contains a surface-inactive component of the sizing agent and a surface-active component of the auxiliary. This is a mixture of a sizing agent and an auxiliary with seemingly contradictory effects, but is a feature of the present invention that improves the efficiency and precision of the dyeing. In addition, depending on the combination with the staining agent (40) described below, there is an effect that the staining agent (40) is excessively diffused and that a plurality of staining agents (40) are prevented from being mixed with each other. Further, the dyeing agent (40) is instantly transferred to various fabrics (10) not only natural materials such as silk at room temperature but in less than one second at room temperature, and the dyed pattern is clear without any defects such as decolorization and color bleeding. , A dyed fabric having high fastness and high weather resistance can be obtained.

First, a white or light-colored coloring agent (40) is charged. As the light color, those of brown, grayish white, and yellow are preferable. As shown in FIG. 2 (a), the white or light-colored stain (41) is applied to the surface of the diluted drug aqueous solution (30) filled in the water tank (20A) by an injection tool (21) such as an air spray. Dispersed thinly and almost uniformly.

Then, as shown in FIG. 2 (b), a variety of yellow, red, blue, black, etc., are placed on the white or light-colored dye (41) by means of a charging tool (21) such as air spray. Color dyes (42) are sequentially charged. As described above, the white or light-colored stain (41) is added to the dilute aqueous solution (3
When the multicolor dye (42) is added after the thin and substantially uniform dispersion on the surface layer of (0), it contributes to the diffusion control of the multicolor dye (42) and clear dyeing. It should be noted that the multicolor dye (42) becomes a light color when diffused greatly, and becomes a dark color when not diffused much.

The dye (40) contains a carbon black organic pigment, polyvinyl alcohol, a colorant, a sizing agent, an activator, a stabilizer, a humectant and a preservative. This prevents the staining agent (40) from settling, mixing the staining agents (42), and preventing color bleeding after transfer to the fabric (10).

The dye (4) floating on the surface of the water tank (20A)
0) is manually agitated using a stirrer (22) such as a metal fitting or a brush, and shaped into a desired blackwashing pattern as shown in FIG. 2 (c). Since this multi-colored sumi-in pattern is formed depending on accidental convection, it is unique,
It gives a natural impression to the viewer, so the artistry and commercial value are recognized.

The desired dyed fabric can be obtained by the above means, but the acrylic resin may be added to the dilute aqueous solution (30) or the dye (40). The acrylic resin acts to fix the dye (40) to the fabric (10). Therefore, it contributes to prevention of decolorization of dyeing and improvement of fastness and weather resistance.

[0024]

The present invention has the following effects by providing the above-described configuration. According to the dyeing method according to claim 1, a multicolor dye is mixed with a dilute aqueous solution containing a sizing agent containing a surface-inactive component and a thickening component and an auxiliary agent containing a surface-active component. Then, the water surface is stirred to form a desired pattern, and the fabric is immersed in the water surface to transfer the pattern. For this reason, ink-wash dyeing, which can freely dye various fabrics into various color patterns with high clarity, robustness, and weather resistance, can be performed with simple operation using simple equipment, and the pattern transfer is instantaneous and reliable. Can be performed.

According to the dyeing method of the present invention, first, a white or light-colored dye is substantially uniformly dispersed on the water surface of a dilute aqueous solution of a drug, and then a multi-color dye is sequentially added. The diffusion of the color dye is adjusted to obtain a clear dye.

According to the third aspect of the present invention, since the natural rubber extract and the seaweed extract are contained in the paste at an equal ratio, the efficiency and accuracy of the dyeing are improved.
