BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a textile dyeing method, and its object is to be able to express a pattern pattern having a variety of deep gradations, which has a fantastic and novel blurring tone. In particular, it is an object of the present invention to provide a method for dyeing a fabric, which is capable of obtaining a dyed product with high added value that can satisfy consumers' demands as a yukata fabric.

[0002]

2. Description of the Related Art Yukata has been popular for a long time as a relaxing wear for evening chill or as a costume for Bon Odori and summer festivals. As a technique for dyeing this yukata cloth, there are Narumi Shibori and medium-sized dyeing, but medium-sized dyeing that can express a pictorial pattern is generally adopted. Among them, the medium dyeing method is very efficient because it can be used for both patterning and dyeing in the same factory.
Moreover, since it can be mass-produced, it is now widely used as a synonym for yukata dyeing. This medium-sized dyeing method is a method in which a paper pattern about the size of a hand towel is fixed to a wooden frame, the fabric is folded and patterned, and the dye is poured in from the top to dye, and the dyeing method is not dip dyeing. It is characterized by being a pouring dye, and there are different dyes that can be dyed in different colors with one pattern, and Hosokawa dyeing that uses two patterns to add and shade patterns.

On the other hand, consumers' fashion preferences have been diversified year by year, and more novel patterns have been demanded. In order to increase the commercial value of the dyed product in response to such a demand, a method of expressing a blur pattern on a fabric has been conventionally used. As a method of expressing this blur pattern, there has been a method of using a roller, for example. This method forms irregularities on the roller surface, changes the depth and spacing of the irregularities,
It was a method of expressing a blurry pattern on fabric by printing. Alternatively, at least one of the printing density gradient or the coating density gradient is applied on the article by passing the step of printing a color paste in a pattern and the step of applying a sizing agent aqueous solution containing a surfactant. There is also a blur pattern forming method in which the color is formed after the formation. Furthermore, there is also a technique of expressing a blur pattern by causing the dye to adhere to the cloth by changing the density difference thereof by tilting the printing table and an appropriate addition means.

[0004]

However, in the blurry pattern expressed by printing using the above roller,
There is a problem in that consumers are easily bored because they are artificial in appearance and cannot express a natural blur pattern. In addition, when a printing density or a coating density gradient is formed and then a coloring process is performed, or when a blurring pattern is expressed by changing the concentration difference of the dyes to be attached, generally, as shown in FIG. Only the monotonous blurring pattern formed by the difference in the shade of the color forming A) in one direction can be expressed, and again there is a problem that the consumer is easily bored. In addition, there is a problem in that it takes much time and effort to express a more diverse and varied blurring pattern by the above method, and the manufacturing efficiency is deteriorated. Therefore, in the industry, unlike the blurriness pattern that has been expressed by the conventional method, a more fantastic and novel blurriness pattern that can satisfy the diversifying consumer demands year by year is expressed in a simple way. It has been desired to create an excellent dyeing method that can be performed.

To do.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The constitution of the method for dyeing fabric according to the present invention will be described in detail below. The dyeing process of the fabric of this invention is
It is composed of a primary dyeing process and a secondary dyeing process. First,
The primary dyeing step will be described in detail. In the primary dyeing step, first, a sizing agent is applied to the surface of the fabric which has been pretreated as necessary. As the cloth used, cloth made of natural fibers such as cotton and hemp is preferably used. As the sizing agent, a sizing agent composed of a mixture of a printing sizing material and a dye-proofing agent is used.

As the paste for printing, the usual pastes used in "Yuzen dyeing" and the like, for example, tracant rubber, mapro gum, methyl cellulose, carboxymethyl cellulose and the like can be preferably used, and one or two of them can be used.
A mixture of one or more kinds, or a mixture obtained by appropriately adding cloth laver, raw starch paste, glue, etc. to the paste can be suitably used,
There is no particular limitation. The method for adjusting these pastes is also arbitrary, and for example, a solution obtained by dissolving about 20 to 40 parts by weight of the above paste in 100 parts by weight of boiling water can be preferably used. On the other hand, as the stainproofing agent, those known as chemical stainproofing agents, that is, hydroxymetasulfonate, tartaric acid, sodium acetate, sodium thiosulfate, sodium hydrogen sulfite, aluminum sulfate, zinc dust, amines, etc., are particularly preferable. It can be used without limitation. In particular,
The reaction-preventing agent of "GCR-13" (trade name, manufactured by Nippon Senka Co., Ltd., hydroxymetasulfonate) can be preferably used, but the present invention is not particularly limited thereto. Such a dye-proofing agent is prepared by using the adjusted paste 100.
The mixture is used in a ratio of about 40 parts by weight with respect to parts by weight.

[0008] A sizing agent composed of a mixture of a sizing material and a dye-proofing agent as described above is used to perform patterning (pasting) on the surface of the fabric. The squeegee (1) for printing is made by attaching a paper pattern (10) engraved in an arbitrary pattern as shown in FIG.
Using. This squeegee for printing (1) is constructed by being hingedly assembled with a work table (11) on which a cloth (2) having a predetermined area is placed. The cloth (2) to be dyed has a predetermined area. Spread it on the workbench (11) for just a minute and make a pattern
Squeegee the sizing agent from the upper surface of (10) to form a predetermined pattern (M) on the fabric surface. At this time, the patterning is performed for each predetermined area, and after finishing the patterning in the predetermined area, the cloth is folded back at a predetermined position, and the upper surface of the patterned area portion is
The same area is folded and folded in a folding tatami mat type, and the squeegee (1) is used again for patterning. In this way, the fabric of the required length is modeled. In the present invention, the work of patterning a predetermined area of the fabric in this manner is repeated while folding the fabric, and the patterned fabrics are stacked on a folding screen tatami mat. By performing such patterning, the sizing agent in the patterned (M) portion is soaked into the back surface of the fabric by repeated patterning work, and good patterning can be performed.

After the patterning of the sizing agent, the folded fabric is
Leave it folded for at least 12 hours,
The dye-proofing agent in the sizing agent is exuded from the contour of the patterned pattern (M). In this way, by leaving the fabric after patterning as it is, the stain-proofing agent in the patterned paste becomes an aqueous solution, which oozes out from the contour part of the pattern (M) imprinted to the peripheral part. It becomes possible to express a fantastic blurring pattern. After leaving for a predetermined time, the cloth is then spread and dried. Here, the cloth (2) left unfolded in a folded state is unfolded and dried to eliminate the creases formed during the molding,
When dyeing, which will be described later, it should be possible to perform uniform dyeing. Further, the drying method is not particularly limited, such as blowing air and hot air,
It may be performed by an appropriate method, but it can be easily performed by using an apparatus as shown in FIG. 2, for example. In other words, the cloth (2) after patterning is conveyed by using a plurality of rollers (3), (3), ... Installed at a high position, and the heat source device (4) is installed at an arbitrary position in this conveying step. Keep it. Then, by driving the roller (3), the cloth (2) is conveyed while facing the heat source device (4), and the cloth is dried in the stretched state, so that the working efficiency becomes very good.

After the completion of drying, the cloth is spread and dyed.
The dye used is dichlorotriazine (trade name;
Procion M, Micacion, etc.), Monochlorotriazine (Product name: Cibacron, Procion H, etc.), Trichlorpyrimidine (Product name: Reactone, Drimalene, etc.), Sulfate ester of oxyethyl sulfone (Product name: Remazole, etc.), Acrylamide derivative (Product) Reactive dyes such as name; primazine etc.) and dichlorquinoxaline (trade name: Levafix E etc.) are preferably used. Further, the dyeing method is not particularly limited as to the cloth, but the pad dyeing method is preferable because the dye can penetrate into the fiber structure of the cloth. Specifically, the use of a pad dyeing machine (5) as shown in FIG. 3 enables efficient dyeing. That is, after the patterning, the dried cloth (2) is conveyed by the conveying means (51) to the padder (5) including the dye solution tank and the roller.
2) Pass it inside. In the padder (52), the cloth (2) is dipped in the dye solution (S) while being squeezed by a roller.
The cloth (2) dyed by the padder (52) is a conveying means (51).
It is transported by the vinyl sheet (6)
Are conveyed in parallel with the dyed fabric (2), the dyed fabric (2) and the vinyl sheet (6) are laminated and wound into a roll (see the sectional view of FIG. 4). It The dyed fabric (2) is laminated with the vinyl sheet (6), and is left in the rolled state for at least 12 hours to stabilize the dye. In this invention,
Put the dyed fabric on top of the vinyl sheet (6),
As shown in FIG. 4, it is wound into a roll and left to stand for at least 12 hours so that the action of the dye-proofing agent contained in the typed sizing agent is sufficiently exhibited after dyeing.
That is, if the fixing treatment of the dye described below is performed immediately after dyeing, it is not possible to sufficiently develop the fantastic and novel blur-like pattern which is the object of the present invention.
Leave the fabric for a certain time.

The dyed and abandoned fabric is then spread and dried. Although the drying method is arbitrary, it is preferable to perform the drying using the apparatus as shown in FIG. 2 in the same manner as described above, because the drying can be performed efficiently. After drying, the fabric (2)
Is immersed in an alkaline solution to fix the dye. As the alkaline solution, any solution can be used as appropriate, but "Fixer RC" (trade name, manufactured by Osaka Soda Co., Ltd.,
Sodium silicate) and the like can be preferably used. The method of immersing in an alkaline solution is also arbitrary, and as in the case of the above-mentioned dyeing, using the apparatus as shown in FIG. 3, the cloth dyed by the pad method is dipped in the alkaline solution, and after the immersion, Similarly, it is wound in a roll shape in a state of being laminated with a vinyl sheet and left as it is for at least 12 hours to fix the dye.

After the dye is fixed, the cloth is washed with water by an arbitrary method. After washing with water, the fabric is soaped. As the soaping agent, any soaping agent for reactive dyes can be preferably used, and specifically, "Peletex CA-200" (trade name, manufactured by Miyoshi Yushi Co., Ltd., polycarboxylic acid salt). ) Is 0.5 to 0.3
Those diluted to a concentration of about% are preferably used. In such a soaping treatment liquid, the cloth after dyeing and fixing 2
Soaking is carried out for 0 to 30 minutes. After the soaping is finished, the cloth is washed with water and dried to obtain a primary dyed cloth.

In the primary dyed cloth obtained by the above primary dyeing process, as shown in FIG. 5, the dye-proofing agent in the typed sizing agent oozes out from the contour of the pattern part (M) to the peripheral part. As it soaks into the mold, is dried in that state, and is subjected to a dyeing treatment, it is dyed and finished with the boundary portion of the patterned portion (M) imprinted. Such primary dyed cloth is then subjected to a secondary dyeing step, which is a casting process.

The casting process is performed on the pattern portion (M) of the primary dyed cloth. A known method is preferably adopted as the casting method, and is not particularly limited. That is, as shown in FIG. 6, it is possible to use a dyeing table (6) having a work table (60) connected to a vacuum chamber (61). As shown in the figure, a portion of the primary dyed cloth excluding the pattern portion (M) is thinly coated with the anti-sealing glue (7) and paste is placed. Here, the dye-proof paste is not particularly limited, and includes bran powder, bran, lime, sand,
Known compounds such as salt or a mixture thereof, or a mixture of a seaweed powder boiled product and bentonite can be preferably used. Next, in order to dye the pattern part (M) separately,
An embankment (8) of the dye-proof paste is formed on the contour portion of the pattern portion (M). Next, an arbitrary dye is poured over the primary dyeing cloth (2) for dyeing. At this time, the vacuum tank (61) is driven to improve the penetration of the dye into the cloth, and the dye Suction. When the cloth is washed with water and dried after completion of such casting, a variety of pattern patterns (M) having a fantastic and novel blurring tone as shown in FIG. 7 can be expressed.
