Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transfer printing method, and particularly to a transfer printing method Q using a discharge printing agent.

The dyeing technique conventionally called discharge printing generally refers to removable dyes (dyes that are discharged using a discharge printing agent).

On the other hand, dyes that cannot be discharged with a discharge dye are called non-discharge dyes), and after drying, a glue paste containing a discharge dye is printed, steamed, washed with water, and soaped to create the pattern. A method of discharging only a portion is known.

Alternatively, the ground color is pre-dyed with a removable dye, and after drying, a glue paste containing a discharge dye and a non-removable dye that is not discharged with the discharge dye and has a different hue from the removable dye (rubbing) is used. There is also a known method of printing, steaming, washing with water, and soaping, then coloring and discharge printing in which only the parts of the image have different hues.

The method below will vary slightly depending on the dye type, but 2
．． A specific example of No. 3 will be described below.

(1) Discharge printing of acrylonitrile fibers Discharge printing is carried out using a cationic dye discharging agent and a non-dischargeable dye, and can be roughly divided into reduction discharge printing method and oxidation discharge printing method.

The reduction discharge printing method uses dechlorin or stannous chloride as a reducing agent, and the oxidation discharge printing method uses sodium chlorite or sodium hypochlorite as an oxidizing agent.

Dyes for background dyeing include Zebulon Yellow 3RL (dye manufactured by DuPont), Astrazon Orange 2RL (dye manufactured by Bayer), Astrazon Red 2BL, Maxilon Red BL (dye manufactured by Ciba-Geigy), and Eisenriki Chiron Blue. Typical dyes include GLH (dye manufactured by Hodogaya Chemical Co., Ltd.), Maxilon Blue GRL1 Diacrylic Splash Blue-5RL (dye manufactured by Mitsubishi Kasei Co., Ltd.), and can be easily discharged with stannous chloride.

Next, the non-dischargeable dyes that can be used in the colored discharge printing method are Eisenkatilon Brilliant Yellow 3GLH, Eisenkatilon Yellow 5GLH1 Eisenkatilon Brilliant Red 4 GH1 Eisenkatilon Brilliant Pink FGH, Eisenriki Chiron Brilliant Red 6BH, Cramps Cachiron Brilliant Blue 3RLH, Cramps Cachiron Turquis Blue LH
(All of the above dyes are manufactured by Hodogaya Chemical Co., Ltd.), Diacrylic Brilliant Pink R1 Diacrylic Brilliant Violet FRL.

Diacrylic brilliant blue RHL (dye manufactured by Mitsubishi Kasei Corporation), anthracene red violet F 2 R,
Anthrathin Blue-F 2 R, Suminol Blue 3R
, Suminol Blue 5G (dye manufactured by Sumitomo Chemical Co., Ltd.).

(2) Discharge printing of polyester fibers Polyester fibers have a dense fiber structure and are hydrophobic, making it extremely difficult for discharge printing agents to penetrate and diffuse into the fibers. Therefore, a discharge printing reinforcing agent (carrier) must be used in conjunction with the polyester fibers. better results can be obtained.

Generally, the following two or three methods are known.

Pad a polyester fiber cloth with a nail-removable disperse dye (removable dye), dry it, then print a glue paste containing a removable dye,
After drying, it is steamed under normal pressure to decompose the dye in the printed area, and then
A method of using thermosol or high-pressure steaming to dye the dye in non-printed areas.

Alternatively, a nail-removable disperse dye (removable dye) is padded and dried, then a glue paste containing a discharging agent is printed, and after drying,
A method of discharging printed areas and dyeing non-printed areas at the same time using thermosol or high-pressure steaming.

Alternatively, a glue paste containing a discharge printing agent is printed on ground-dyed cloth,
After drying, discharge printing is performed using thermosol or high-pressure steaming.

Discharging agents that can be used include dechlorin and tin chloride, and dischargeable dyes such as Resolin Yellow 5GS,
Resolin Yellow NL1 Resolin Yellow Brown G
L S, Resolin Orange 3GL, Resolin Scarlet 3GL, Resolin Red RL, Resolin Red BRL, Resolin Lupine BL, Resolin Blue BBLS, Resolin Navy Blue GL
S, Resolin Brilliant Scarlet PGG (
The non-dischargeable dyes used for coloring and discharge printing include Resolin Brilliant Yellow 7GL Paste, Resolin Brilliant Red BS Paste, Resolin Violet RL, Resolin Blue RRL, Resolin Blue FBL Paste 50%, Resolin Brilliant Yellow PGG, Resolin Brilliant Violet PRL (dyes manufactured by Bayer)
etc. are used.

(3) Other methods include white discharge printing using dechlorin for polyamide fibers,
For acetate fibers, use dechlorin (Koyoru Shirabuki, colored discharge dyeing with tin chloride), for regenerated cellulose fibers, use Rongarit C (manufactured by Hoechst), Hydrosulfide R Conc (manufactured by Ciba Geigy), aluminum foil CP (
(manufactured by Daiichi Pharmaceutical Co., Ltd.) etc. are known.

As mentioned above, many types of dye Q are known and put to practical use regarding white discharge printing and colored discharge printing.

However, in all of these methods, discharge printing paste is directly printed onto yarn-dyed cloth, and the ability to express patterns is limited, making it extremely difficult to express elaborate patterns.

In order to solve the above-mentioned problem, the present invention makes use of the advantages of conventional white discharge printing and colored discharge printing methods, and also makes use of the advantages of transfer printing to make it possible to express extremely elaborate patterns. Explain.

As shown in Figure 1, art paper, coated paper, printing base paper,
A transfer resin layer 2 is provided on a transfer paper base 1 such as printing paper such as pure white paper, cellophane, acetate film, aluminum foil, or a film laminated with these, and this resin layer is formed on this transfer resin layer 2. A transfer paper 4 is created by using a resin having similar properties as the resin as a binder and forming a pattern layer 3 by an appropriate printing method, such as a gravure method or a screen printing method, using an ink containing a discharge printing agent. do.

Next, the transfer paper 4 is brought into close contact with the cloth 5 to be dyed, which has been pre-dyed with a dye (removable dye) that can be discharged with the discharge agent contained in the ink, and heated, as shown in FIG. The entire transfer resin layer 2 is transferred onto the transfer paper 4, followed by a steaming process, followed by water washing or solvent soaping to remove the transfer resin layer 2 and the binder in the ink, and then finishing by a normal method. This is a method of discharging white color.

Note that colored discharge printing is also possible by simultaneously containing a non-dischargeable dye that cannot be discharged with a discharge printing agent in the above ink.

Here, the resin and ink binder resin forming the transfer resin layer 2 include polyester resin, polyamide resin, maleic acid resin, vinyl resin, xylene resin, phenol resin, ketone resin, and acrylic resin. , petroleum-based resin, cellulose-based resin, etc., and the temperature is 50℃.
A thermoplastic resin having a softening point at a temperature of about 200°C is suitable.

In addition, the heating transfer conditions are 130 to 200'C.
1 Pressure conditions 1-50kq/c1? L1 speed condition 3~
Approximately 30 m/min is appropriate.

Further, as an alternative method of the present invention, there is also the following method.

That is, as shown in FIG. 3, a transfer resin layer 7 is applied on a transfer paper base 6, and a removable dye layer 8 is applied on the transfer resin layer 7 with an endless plate or a desired pattern using ink containing a removable dye.
, and further contains a discharging agent thereon, and an ink containing or not containing a non-dischargeable dye that is not discharged by the discharging agent (transfer paper 10 on which a pattern layer 9 is appropriately formed by overprinting with a trowel) is formed. The transfer paper 10 is brought into close contact with the cloth 11 to be dyed and heated to transfer the entire transfer resin layer 7 of the transfer paper 10 as shown in FIG. By applying solvent soaping treatment, finishing, etc., the parts where the removable dye and the ink containing the discharging agent overlap are discharged with the releasable dye and the discharged part is dyed with the non-removable dye, or This is a method of color discharge printing or white discharge printing without any process.

In addition, the dyed fabrics that can be used in the present invention include acrylic,
It can be applied to a wide variety of fibers, including synthetic fibers such as polyester and polyamide, natural fibers such as natural cellulose and protein, and blended fibers of synthetic fibers and natural fibers.

Further, the dye can be selected from the appropriate dyes mentioned above depending on the fiber to be applied.

Since the present invention has the above-described configuration, unlike conventional discharge printing methods, it is possible to reproduce extremely elaborate patterns of tweezers.
The present invention solves problems such as connecting patterns, which are extremely difficult from a plate-making standpoint, and has great practical effects.

The effect will become clearer from the following examples.
