Description

Detailed Description of the Invention (Technical Field of the Invention) The present invention uses an ink application method based on the ink jet printing principle, and uses a cloth cloth having a high flexibility as a transfer ink support.
The present invention relates to a transfer cloth which provides a novel printing method capable of performing transfer printing even in a place where transfer is difficult or in a state where transfer is difficult.

(Conventional technology and its problems) The conventional printing process requires plate-making regardless of which printing method is used in order to reproduce an accurate pattern. This plate making is costly and time consuming, and it is quite disadvantageous for the recent small-lot production of various kinds and short product life. These printing methods are rolls for making patterns, or screens are provided in a printing machine for knitting, printing a paste in which a coloring agent is mixed in a dyeing object such as woven fabric, drying, steaming,
Generally, it is washed and finished.

Following roller printing and screen printing, transfer printing became popular for a while. The reason for this is that the transfer paper used for this transfer printing was manufactured under the printing industry, and in the dyeing and printing business, there was a good workability to transfer it to a cloth foil. Even in this case, there was platemaking and there was no change in the process.

On the other hand, the ink support of the transfer paper is paper, and there is a colorant paste on the paper, and this is brought into close contact with a cloth cloth, which is a dyeing object, and is pressed and heated to perform transfer. However, paper has the drawback that it is not soft, that it is not easily bendable, and that it is easily scratched and torn.

(Purpose of Invention) The present invention solves these drawbacks of transfer paper, and pays attention to combining manufacturing methods that omit plate making when making transfer paper, and as a result of earnest study, CAD (Computer Aided Design)
(Hereinafter abbreviated as CAD device) and ink jet printing technology, and by using the ink support as a cloth strip,
We have established a new transfer cloth that eliminates the defects of the prior art. That is, (the structure of the device) The present invention has a fabric weight of Ag / m ² and a thickness of Bmm of 15
A transfer cloth characterized in that an ink layer is formed by inkjet printing on a support made of cloth foil satisfying ≦ A × B ≦ 40 gmm / m ² via a non-dyeing polymer compound film. .

(Means for Solving the Problem) The cloth foil used as the ink support in the present invention is selected from woven fabrics and knitted fabrics composed of vegetable fibers, animal fibers, and synthetic fibers. That is, which fiber is selected depends on the chemical structure of the pigment that is the main component of the ink. The pigments that are the main components of the ink are classified by conventional dyeing science, and those having the same chemical structure as this dye are used. That is, they are disperse dyes, direct dyes, acid dyes, cationic dyes, reactive dyes and the like. These are classified as nonionic, anionic, and cationic in terms of ion. First, since ionically nonionic disperse dyes show good dyeing properties to diacetate, triacetate and polyester fibers, these fiber groups are not preferable for the ink support cloth of disperse dyes. Vegetable fibers and animal fibers which do not have good dyeing properties to disperse dyes, especially vegetable fibers, are preferred for the ink support cloth of disperse dyes. On the contrary, direct dyes, acid dyes, cationic dyes, and reactive dyes that are ionically anionic and cationic show good dyeing properties on plant fibers and animal fibers. Therefore, these fiber groups are ink supports for these dyes. Cloth is not suitable for cloth. Diacetate, triacetate, which does not have good dyeing properties with these dyes,
Polyester fibers are preferred for ink carrier fabrics of these dyes. If an ink support that is dyed is used, the dye to be dyed and the dye in the ink both share the dye and the yield of the dye is lowered, which is not preferable.

In other words, the cloth to be dyed is determined, and when the dye to be dyed is determined, the cloth to be the ink support is the fiber cloth which is not dyed with the dye in the ink. To be elected. The cloth foil may be woven or knitted, but as described above, this ink jet printing serves as an ink support for ejecting ink onto the cloth foil to form a desired pattern by ink jet printing. A cloth that is easy to make, has good pattern formation quality, and has good adhesion to the material to be dyed and good transferability. Foil is preferred. For this purpose, the fabric weight A (g / m ² ) and thickness B (mm)
Then, it is necessary to satisfy 15 ≦ A × B ≦ 40 (g · mm / m ² ). In this case, the basis weight and thickness conform to JIS L1096 and are obtained by measurement. The process of deriving the numerical condition will be described here. The data are shown by excerpting the results of comparing the basis weight, thickness, and quality of transfer cloth for 9 kinds of polyester cloth foil and 11 kinds of cotton cloth foil from 100 or more kinds of cloth foil samples.

Although there is no numerical meaning of the unit weight A × the thickness B here, from the viewpoint of four relations of unit weight, thickness, and quality as a transfer cloth, the one in which the unit weight and the thickness are well balanced as the cloth is the equivalent value. It can be judged that the conditions are satisfied and the quality of the transfer cloth is good. The basis weight and thickness are determined by the type of single yarn, the processing of the yarn, the number of bundles, and the structure, and it is not appropriate to be too light or heavy to satisfy the numerical conditions, and the thickness is It seems that thin or thick is inappropriate.

The material to be dyed in the present invention covers all materials that can be dyed with the dye. For example, when a pigment obtained from a disperse dye is used, polyester, diacetate, triacetate, polyamide or the like can be the dyeing object.

Direct dye, acid dye, cotton, rayon, silk, wool,
Polyamide, polyvinyl alcohol, etc. can be the dyed body.

If it is a cationic dye, cotton, rayon, silk, wool, polyamide, polyvinyl alcohol, acrylic, cationic dyeable polyester and the like can be used as the dyeing object.

If reactive dyes are used, cotton, rayon, silk, wool, polyamide, polyvinyl alcohol and the like can be dyed.

The transfer cloth is adjusted as follows. The cloth used as the ink support is well refined, oil, dirt and impurities are removed well, the warp density, the weft density or the knit density is set to the most stable, and the tissue is fixed using hot air or a hot roll. For this fixing, it is necessary to set a high condition so as not to be deformed by dry heat and wet heat treatment which perform a transfer operation. In addition, a film of non-dyeing polymer compound is formed on the cloth foil so that the ink does not bleed and the transfer is easy.
So-called pretreatment is performed.

The non-staining polymer compound used here is gum arabic, guar gum, locust bingham, silagum, sodium alginate, carboxymethyl cellulose, carboxymethyl starch, cloth foil used in sodium polyacrylate, etc. The above mixing is also performed. In addition to this, an antiseptic agent, an anti-reducing agent, a fixing aid, a fixing reaction agent, a fixing accelerator, etc. are added to the aqueous solution of the polymer compound. Of these compounds, it is also possible to provide them separately to either the cloth of the ink support or the material to be dyed, or both, except the preservative.

This pretreatment is performed by a pad method, a coating method, a screen method, a spray method or the like. The ink is adjusted so that the well-purified pigment and surface tension, specific electric conductivity, viscosity, PH, particle size, etc. can be printed by an ink jet printing device.

It is preferable that these applied amounts in the pretreatment satisfy 1/200 to 1/4 times the weight of the support. A procedure for making a transfer cloth foil by the ink jet printing method will be described below.

1) Design The pattern on paper, the pattern on cloth, the pattern on the film, or the plain color, which is the desired design source, is read by the CAD device, and the pattern is laid out and modified to form the color instruction.

2) Cloth foil Prepare the desired cloth foil without proper pretreatment.

3) Ink Fill the device with an ink of the type suitable for the desired cloth foil.

4) Printing Printing is performed according to the instructions of the CAD device. The printed cloth foil becomes a transfer cloth foil. The ink jet printing apparatus is available on the market as an electrostatic suction method, an ultrasonic vibration method, a piezo element method, etc., but the method is not limited.

The present invention has been demonstrated using one of these on-demand devices. The transfer cloth is provided with the following means in order to improve the close contact with the material to be dyed.

1) An adhesive component is applied to the ink support, that is, the transfer cloth, to improve the adhesion with the article to be dyed.

2) In the same manner as in 1), an adhesive component is previously applied to the ink support by a similar method to the ink support.

3) Improving the adhesiveness by using both means of 1) and 2) at the same time.

Such an adhesive component consists of the so-called adhesive polymer elastic body and the components of the tackifier as the skeleton, but in the present invention, the adhesiveness is 180 degrees and the peeling force is weak such as 20 to 50 g / 15 mm. Yes, it is only added in a trace amount in the non-dyeing polymer compound. Alternatively, only the adhesive component can be separately added. A spray method or a coating method is suitable for this. As the polymer elastic body, there are natural rubber, styrene-butadiene copolymer, butadiene polymer, and chloroprene polymer as the diene elastic body, and acrylic ester copolymer and vinyl ether copolymer as the ethylene elastic body. The condensation type elastic body includes polyurethane, silicone resin and the like.

Examples of the tackifier include rosin, dammar, copal, hydrogenated rosin, hydrogenated rosin ester, coumarone indene, polyester pen, phenol resin, alkyd resin, petroleum hydrocarbon resin, xylene resin, and epoxy resin. If these pressure-sensitive adhesive components are made to directly touch the fiber surface of the dye-receiving material, and if the pressure-sensitive adhesive component remains, it causes discomfort. In this case, the amount applied by the pretreatment is to avoid direct contact of the adhesive component, and may be 1/2 or less of the amount applied to the ink support.

The transfer operation is performed as follows. The ink support and the material to be dyed are superposed and pressed to improve the adhesion. A simple iron and press are used for this, and a padder is used for the extended long material. After pressurization, a fixing operation is performed by dry heat and wet heat treatment. In the case of a pigment made of a disperse dye such as polyester, triacetate, diacetate, or polyamide, it is fixed at a dry heat of 100 to 200 ° C, a high-pressure saturated steam of 100 to 150 ° C, and a superheated steam of 105 to 185 ° C. Saturated steam 80 for pigments from direct dyes such as cotton, silk, wool, polyamide, polyvinyl alcohol, acrylic, acid dyes, cationic dyes, reactive dyes, etc.
It is fixed at ~ 150 ° C and superheated steam 105-185 ° C. After fixing, a cleaning operation is carried out to remove unfixed dye, non-dyeing polymer compound and other additives by peeling from the ink support or as it is. As these conditions, those determined in advance depending on the type of material and the type of dye are used.
The transfer cloth is not only used for a cloth-exposed object but also for the object to be dyed at the sewing stage. That is, after inserting a pattern cutting line in the article, the transfer cloth is fixed and transferred in the line. Furthermore, the transfer cloth can be used after sewing. That is, the sewn garment is fixed to an anthropomorphic model, a so-called mannequin doll, in a worn state, and the transfer cloth is fixed and transferred at a desired position. These transfer operations are the same as those described above for cloth foil.
