Description

The present invention relates to a transfer paper for dry transfer printing for preventing and discharging a fabric made of a natural or synthetic fiber material, and a dry transfer printing method using the same.

2. Description of the Related Art Conventionally, a processing method for imparting a design to a fabric by a technique such as a discharging method (white discharging or colored discharging: the same applies hereinafter), an anti-discharge method, or an anti-dyeing method using a discharging agent or an anti-dyeing agent is known. When these techniques are used, screen printing, roller printing, rotary screen printing, gravure printing or transfer printing using these printing techniques are known and practiced industrially.

Here, printing is a general term for methods of dyeing fabrics and the like into multicolored patterns, and is classified into direct printing (overprinting), discharging, anti-dyeing, anti-dyeing, etc., depending on the technique. This is in contrast to plain dyeing such as dyeing and continuous dyeing. In the above-mentioned classification, discharging is performed by grounding a fabric with a removable dye (plain dyeing), and then printing a printing paste containing a discharging agent (corresponding to ink in ink-jet printing), and a printing portion (that is, a pattern). Part)). The one that prints only the discharge agent and makes the pattern part white is called white discharge, and the one that prints the discharge agent and anti-discharge coloring material and colors the pattern part in a different color is called colored discharge. It is considered to be a high quality product. In the color discharge, the discharge-resistant coloring material used for coloring the pattern portion is referred to as an insertion color material (coloring), and the color of the pattern portion colored with the insertion color material is referred to as an insertion color.

However, these conventional plate-making printing methods have many problems such as high cost of plate-making in small-lot production, inability to respond to short delivery times, inability to provide fine design, and high wastewater load. As a new processing method for solving these problems, a plate-free print that is image-processed by a computer and printed by an ink jet method is in the spotlight, and the practical use of a direct printing method on a fabric is accelerated. However, when printing directly on a fabric by ink jet printing, the same applies to both dye solution and discharging ink, but there are problems such as ink bleeding and loss of delicateness. Pre-treatment is essential.

Employing such a direct printing method requires fabric pre-processing equipment and pre-processing steps, and there are many different forms such as yarn thickness, twist strength, weaving method, and knitting method. Since it is necessary to optimize the pre-treatment conditions of the fabrics to be included, the process becomes complicated, which causes an increase in cost, and it is conceivable that the non-rise rate also increases. In addition, the weak point of the inkjet printing method is plain dyeing, and in the case of plain dyeing, especially in the case of dark solid color printing, a large amount of ink is required, the time required for printing increases, and the fine design that characterizes inkjet printers It does not take advantage of the function of giving Therefore, it is general to perform plain dyeing by exhaust dyeing, continuous dyeing or semi-continuous dyeing (cold pad batch dyeing).

Several patents (Patent Documents 1 to 4) are disclosed as methods for imparting a pattern to this plain dyed fabric by white discharging, coloring discharging or anti-discharge discharging. All of these methods are methods for printing directly on a fabric, and have many of the problems described above.
In order to solve these problems, the present inventors have previously described a unique and novel “dry transfer printing method of natural or synthetic fiber materials with water-soluble dyes” (Patent Document 5, Patent Document 6, etc.).

In the present invention, for example, this dry transfer printing technique may be referred to as a white discharge method, a colored discharge method, a white anti-discharge method and / or a color anti-discharge method (hereinafter referred to as dry transfer printing method for prevention / discharge). ).

As the ink receiving layer, a mixture of a hydrophilic synthetic resin that is softened or melted by heating, a hydrophilic paste, and various auxiliary agents (hereinafter, the mixture may be referred to as “ink receiving layer paste”). It is a more preferable embodiment of the present invention to be laminated using.

The dry transfer printing method for preventing and discharging according to the present invention is a method of printing or applying an ink containing a preventing and discharging agent (including a coloring material if necessary) on a transfer sheet to produce a transfer sheet. Dry transfer printing method for preventing and discharging, in which a fabric (stained or unfixed fabric) made of a synthetic fiber material is brought into close contact with a pressure and heat treatment to be transferred and then subjected to a wet heat treatment (coloring and / or fixing treatment). The transfer paper comprises a synthetic resin soluble in an organic solvent as a release agent layer, and a hydrophilic synthetic resin, a hydrophilic paste, and various auxiliary agents that are softened or melted by heating as an upper ink receiving layer. This is a dry transfer printing method for preventing and discharging, characterized by being laminated (Item 12).

The following two methods are considered in the dry transfer printing method for preventing and discharging according to the present invention.
First, the following (1) to (5)
(1) Fabrication process for fabrics made from natural or synthetic fibers
(2) Production process of ink containing anti-discharge / discharging agent (including color material if necessary)
(3) Transfer paper production process
(4) A step of producing a transfer paper by printing or applying an ink containing the anti-discharge agent (including a color material if necessary) on the transfer paper.

(5) A dry transfer printing method for preventing and discharging fabrics made of natural or synthetic fiber materials, comprising a step of applying a heat treatment ((coloring and / or fixing)) with a colorant to the dyeing-proof fabric (Item 14) ).

More specifically, one of the preferred embodiments of the present invention is an ink jet system in which an ink (including a coloring material if necessary) containing an anti-discharge agent is applied to a transfer sheet having a specific configuration as a feature of the present invention. The printed paper is then printed to form a printed pattern, and then the transfer paper is transferred to the fabric (dyed fabric or non-fixed fabric) made of natural or synthetic fiber material by pressure and heat treatment, and finally wet. This is achieved by obtaining a discharged fabric by heat treatment (color removal or coloring treatment).

Hereinafter, the structure of the transfer paper, which is a feature of the present invention, will be described in more detail.
That is, the present invention provides a transfer paper by applying and drying the ink receiving layer paste as an ink receiving layer on a transfer base paper coated with an organic solvent-soluble synthetic resin layer as a release agent, The transfer paper is produced by printing or applying an ink (including a color material if necessary) containing an anti-discharge agent to the transfer paper. Here, the coating amount of the ink receiving layer paste applied over the release agent is preferably usually ^{15g / m 2 ~80g / m 2} , a ^{20g / m 2 ~50g / m 2} . If the transfer rate is 15 g / m ² or less, the transfer rate of dyes in transfer and anti-discharge agents (hereinafter sometimes referred to as “medicine”) tends to be insufficient, and more than 80 g / m ² In this case, the drying after coating is slow, the productivity is lowered, and the detergency after the dye fixing treatment is deteriorated.

Next, the present invention is characterized in that the ink receiving layer paste is composed of multiple components and the composition is optimized so that the ink containing the anti-discharge agent on the transfer paper (including the color material if necessary) is printed. As the ink is absorbed and dried, the design is quickly fixed and stabilized so that the design does not blur, and the transfer and release properties are good. A transfer paper that can be made 100%, has high reproducibility, and is capable of robust and delicate transfer has been developed. In this case, transferability is significantly reduced under coating conditions in which a large amount of hydrophilic paste is in direct contact with the release agent layer. In order to solve this problem, the inventors of the present invention have an important composition ratio between the hydrophilic synthetic resin and the hydrophilic paste as the ink-receiving layer, and specifically, for 100 parts by weight of the hydrophilic synthetic resin. The present invention has found that it is particularly preferable to use an ink receiving layer in such a range that the hydrophilic paste is contained in an amount of 1 to 50 parts by weight, more preferably 5 to 30 parts by weight (Item 2).

In the present invention, the advantage of using the ink receiving layer paste is that no special treatment is required for the fiber material to be transferred and printed, and the transfer paper can be prepared by simply applying and drying the ink receiving layer paste on the transfer base paper. The transfer paper is prepared by printing or applying ink (including a coloring material if necessary) containing an anti-discharge agent to the transfer paper to produce the transfer paper, and the transfer paper is in close contact with the fiber material and subjected to pressure and heat treatment. And then wet-heat-treating (coloring and / or fixing) to complete the dry transfer printing method for prevention and discharge, so that quick delivery is possible by so-called plate-free printing, and sharp A high-density, high-quality, and high-stiffness design can be easily obtained, and a completely new transfer printing method corresponding to cost and ecology has been established.

Furthermore, in the ink receiving layer used in the present invention, it is essential to add and laminate various auxiliary agents in addition to the hydrophilic synthetic resin and the hydrophilic paste, and as various auxiliary agents to be added and laminated, PH adjusting agents, Selected from buffer, alkali agent, surface tension modifier, viscosity modifier, moisturizer, foil transfer binder, thickening agent, preservative, antifungal agent, antistatic agent, sequestering agent and antireduction agent It is characterized by being 1 type or 2 types or more (Claim 3).

Here, as the pH adjuster, a so-called weakly acidic substance made of an organic acid alone or an ammonium salt of an organic acid or an inorganic acid, which is acidic itself or selected from substances that become acidic by heating, is included. Therefore, the present invention is extremely effective in solving the problems of the present invention (particularly, improvement in dyeing rate). The buffering agent is also used for the same purpose as that of the pH adjusting agent.
Examples of the alkali agent include a function of a color remover by hydrolysis of a disperse dye and a reactive dye and a function of fixing the reactive dye.

As the surface tension modifier, fatty acids, alcohols, aldehydes, ethers, esters, amines, tempel, etc. are effective. Specifically, for example, nonionic and anionic surfactants, methanol, ethanol, ethyl Examples include ether, triethanolamine, diethanolamine, acetone, chloroform, sodium diethylhexylsulfosuccinate, and polyether-modified polydimethylsiloxane. Specific product names include Meisanol TR (anionic activator: manufactured by Meisei Chemical Co., Ltd.), Ionette 300 (nonionic activator: manufactured by Sanyo Kasei Kogyo Co., Ltd.), Plus Coat RY-2 (fluorine-based 10% liquid: Mutual Chemistry) Manufactured by Kogyo Kogyo Co., Ltd.), and 0.1 to 5% is added to the ink receiving layer paste including the above chemicals. These are effective as water repellency preventing agents when the ink receiving layer paste is applied.

As the viscosity modifier, acrylic synthetic glue is effective. As specific trade names, thickener-F (anion type: manufactured by Sano Co., Ltd.), high print LN-11R (anion type: Hayashi Chemical Industries) And Daishi Print ST (manufactured by Kyoto Glue Co., Ltd.) and the like, and can be used in an amount of 0.1 to 3% with respect to the ink receiving layer paste.

Specific examples of the humectant include polyethylene glycol (MW 200 to 600), glycerin and the like, and 1 to 5% of the ink receiving layer paste can be used.

Specific examples of the binder for foil transfer include those based on nylon powder, acrylic resin, and the like, which are effective for promoting the transfer of the hydrophilic synthetic resin.

Specific examples of the antiseptic and antifungal agent include neosynthol LB (preservative: manufactured by Sintfine), neosynthol TF-1 (antifungal: manufactured by Sintfine), and Amorden FS-100 (antiseptic / antifungal agent). : Organic nitrogen sulfur compound: Yamato Chemical Co., Ltd.), Protectol N (antiseptic / antifungal agent: parachlorometacresol type: Okamoto Dye Store Co., Ltd.), etc. Preservatives), used for the purpose of anti-rusting during storage of the applied ink receiving layer.

Examples of the sequestering agent include ethylenediaminetetraacetic acid and its mono-, di-, and tri-sodium salts.
Specific examples of the reduction inhibitor include sodium chlorate and sodium metanitrobenzene sulfonate, which are used to improve the dyeing stability in the steam treatment of the transfer fabric, that is, the color-change colorant used in combination with the color remover. Used.

As the transfer base paper used in the present invention, pulp paper made from pulp such as kraft pulp or grind pulp or recycled paper, recycled paper, or heat-resistant synthetic resin film such as polyester film is used. In view of workability, the weight is preferably 10 to 150 g / m ² and the thickness is preferably about 0.01 to 0.5 mm.

Such transfer base paper is made of organic resin-soluble synthetic resin, specifically silicon resin, fluorine resin, polypropylene resin, polyethylene resin, acrylic resin, alkyd resin, polyamide resin, phenol resin, stearic acid resin, polyester resin, etc. It dissolves in a solvent such as ethyl acetate, toluene, xylene, methanol, ethanol, propyl alcohol, etc., and is applied and dried as an organic solvent varnish to form a release agent layer. The thickness of the release agent layer is preferably about 10 to 30 μm. As these transfer base papers, for example, commercially available polyethylene laminated kraft paper can also be used. In the case of a film having the same composition as that of the release agent, there is an advantage that it can be used as it is without applying the release agent.

On this base paper for transfer, as the ink receiving layer, a hydrophilic synthetic resin that is softened and melted by heat, specifically, a water-soluble polyester resin (for example, plus coat Z-850, plus coat Z-221 and plus coat) Z-730: All of the above, all manufactured by Kyodo Chemical Industry Co., Ltd.), water-soluble polyamide resin (for example, water-soluble nylon: sold by Sano Co., Ltd.), water-soluble urethane resin, water-soluble urethane-modified ether resin (for example, HA resin PE) -1B: manufactured by Meisei Chemical Co., Ltd.), water-soluble polyvinyl alcohol-modified resin (hot melt type), excival resin, HP polymer (manufactured by Kuraray Co., Ltd.), and other water-soluble acrylic resins (for example, binder 812-A-1) : Manufactured by Sano Co., Ltd.) and water-soluble polyethylene oxide resin (for example, Alcox E-30: manufactured by Meisei Chemical Industry Co., Ltd.) One or two or more kinds and a hydrophilic glue for temporarily fixing the printing ink on the transfer paper, such as natural gum glue (etherified tamarind gum, etherified locust bean gum, etherified guar gum, acacia arabic gum) Etc.), fiber-derived paste (etherified carboxymethylcellulose, hydroxyethylcellulose, etc.), modified starch paste (etherified starch, esterified starch), water-soluble synthetic paste (polyacrylate, polyvinyl alcohol, etc.), seaweed paste (alginic acid) Ink-receiving layer paste mainly containing one or more selected from soda) has a viscosity of 3,000 to 30,000 MPa (Millipascal second), a coating amount of Wet 20 to 100 g / m ² , and a dry time of 10 to 10. It is applied to 50 g / m ² and a thickness of about 10 to 60 μm. The hydrophilic paste further contains a mineral paste (specifically, for the purpose of accelerating the absorption of the dye and / or anti-discharge agent ink into the ink receiving layer and enhancing the drying property of the surface). , Silica, diatomaceous earth, clay, talc, bentonite, acid clay, etc.) can also be added.

In the present invention, since the thickness of the ink receiving layer to be applied is related to the degree of difficulty when the resin is softened and melted and transferred to the cloth, and the washing removal property after the dye fixing process, the ink receiving layer paste is coated. When applying with a machine, it is important to control the amount of adhesion. Further, depending on the type of the hydrophilic synthetic resin, a water repelling phenomenon may occur at the time of application, and uniform adhesion with the release agent may be difficult. The phenomenon of water repellency varies depending on the type of paste and paste solid content, the type and amount of surface tension reducing agent (anionic, nonionic surfactants, alcohols, etc.), etc. It needs to be adjusted. Moreover, 0.5 to 3% of an acrylic acid synthetic paste can be arbitrarily used for increasing the viscosity of the ink receiving layer paste during coating.

As a fabric (dyed fabric or non-fixed fabric) made of a natural or synthetic fiber material applied to the dry transfer printing method for prevention / discharge printing according to the present invention, fibers are first classified into the following three types.
1) Natural fiber: vegetable (cotton, rayon, hemp), animal (wool, silk)
2) Synthetic fiber: synthesized from petroleum and coal (polyester, polyamide, polyacrylonitrile, etc.)
3) Semi-synthetic fiber: Chemically treated plant fiber (triacetate, diacetate, etc.)

In order to perform discharge discharging and prevention discharge discharge of these fibers, they are used in the following two forms.
A) Dyed cloth ---- (used for discharging) = a method of partially removing the color material from the dyed cloth,
1) It is necessary to select a colorant that can completely remove the discharge prescription and processing conditions, and to consider the surface dyeing at the time of dyeing to promote the discharge.

    2) Even if the dye of the ground dye can be removed by itself, there are cases where the color remains when the blended dye is used. This is because the discharge speed of each dye is different, so that the discharge agent is consumed easily, and the amount of effective discharge agent is decreased in turn, so that a slow-release dye further becomes defective in color removal and remains in color.

B) Non-fixed fabric --- PAD-DRY with the anti-discharging dyeing pad method dye, print the discharging agent in the non-fixed state, dry and moist heat treatment, dyeing the ground dye on the unprinted part of the discharging agent, and discharging Simultaneously discoloration of the ground dye in the agent print section.
Post ironing method (post pad method)
After printing and drying the discharging agent, the surface dyeing dye paste is coated on the entire surface, dried and wet heat treated.
The characteristics of the discharge method and the anti-discharge method are shown in Table 1 below.

As described above, the present invention is characterized in that a transfer paper is produced by printing or applying an ink containing an anti-discharge agent (including a color material if necessary) on the transfer paper. Here, the ink containing the anti-discharge agent and the production method (procedure and points to be noted) will be described.
Composition of ink composition 1) Discoloring agent for ground dye 2) Dissolving agent for discoloring agent and coloring material 3) Moisturizing agent for preventing clogging of inkjet printer nozzles 4) Improving ink flow and leveling Surface tension reducing agent for enhancing 5) Preservative for preventing decay of ink components 6) Chemicals for promoting dyeing of coloring materials and promoting discharge effect

The ink is adjusted by adjusting the type and amount of the medicine in consideration of the discharge operation conditions. In this case, water-soluble colorants can be mixed directly with the above ink liquid, but water-dispersible disperse dyes, vat dyes, etc. are large in particle size and will cause clogging of the printer nozzles. The particle size must be crushed to 0.5 μm or less, adjusted to a fixed particle size with a filter, and then added to the ink composition liquid. Furthermore, in order to increase the flow of the printer nozzle, it is deaerated and used in a sealed container.

Next, for an ink containing an anti-discharge agent (including a coloring material if necessary), the ink containing the anti-discharge agent includes an alkali agent, a sulfite compound, an organic acid, various surfactants and other reducing agents ( 1 type or 2 or more types of the coloring agent selected from the sulfin type | system | group, a stannous type | system | group, an amine type | system | group, or the anti-dyeing agent is characterized by the above-mentioned. Here, the color removal agent or the anti-dyeing agent is a compound that discolors or decolorizes or hydrolyzes the dye and loses the affinity with the fiber. Specific examples include the following.

It is characterized by being transferred by applying pressure and heat treatment in close contact with a fabric (dyed fabric or non-fixed fabric) made of, followed by wet heat treatment (color removal and / or fixing treatment).

The wet heat treatment (discoloration and / or fixing treatment) is a step of performing dyeing of the ground dyed cloth (pigment decomposition) and dyeing of the non-dyed part of the dyed dye (also applicable to the anti-discharge cloth), Usually, fixing equipment used for textile printing can be used. Examples of usage conditions for these facilities are shown below.

Further, a composite fiber of natural fiber and synthetic fiber may be used. It should be noted that an auxiliary agent effective for penetration and diffusion of the dye, for example, urea pretreated with 5 to 20% Pad-Dry, may be used as the fabric during transfer.

The present invention is an invention relating to the practical application of a so-called inkjet print transfer method for preventing and discharging a delicate pattern that has conventionally been regarded as difficult and with good reproducibility, and has been established overcoming many difficulties. It is a rare new technology.
That is, for example, "stability of transfer paper" (the anti-discharge agent applied as a pattern during storage of the transfer paper does not decompose or peel off or contaminate others) and "transferability" (with short heat treatment) There is a contradiction between the two physical properties of being able to efficiently and cleanly transfer the anti-discharge / discharging agent. However, this is a technology that harmonizes and balances these contradictory properties, and the side of the fiber material that is the transfer target. The invention deserves special mention in that it has developed a one-phase transfer method that does not require any special treatment (alkali treatment or paste treatment) and can be easily transferred and fixed by anyone with simple equipment.

In addition, there is an advantage that the heat transfer equipment frequently used for sublimation transfer printing such as polyester fiber can be applied as it is, and the practical value is extremely large. In particular, the method of the present invention is not only capable of building small-scale, high-mix production, which has become increasingly important in recent years, and industrial production systems that can respond quickly and efficiently to diverse needs, but also high quality that can be easily enjoyed at home.・ Technology that can provide functional transfer paper, and is an environmentally compatible method with excellent economic efficiency and quality effects (delivery, robustness, texture, etc.). It is a new method that greatly contributes to

As described above, according to the dry transfer printing method for prevention / discharge printing according to the present invention, it is possible to deal with small lots at a low cost, and to obtain a dressing / discharge / resistant with excellent quality. In particular, it simplifies complex textile printing technology and is advantageous not only for industrial production, but anyone can freely choose a pattern that suits their tastes, and it is clear, robust, and textured for various fiber materials. There is a unique effect that the design can be printed.

Among them, the dry transfer method for preventing and discharging according to the present invention comprises a hydrophilic synthetic resin that can be easily peeled off from the release agent layer by being softened or melted by heat as an ink receiving layer on the base paper for transfer, In addition, a hydrophilic paste that uniformly absorbs and holds the ink to be printed, improves leveling and eliminates dot spots at the time of transfer to a fabric, and a dye fixing agent for coloring, and if necessary, a known foil transfer binder paste Ink containing anti-discharge agent (including color material if necessary) is printed on the transfer paper coated with a paste mixed with humectant, surfactant, etc. by inkjet printing method, etc. Attaching or giving a pattern such as a figure or a pattern, drying this to produce a transfer paper, and using the transfer paper, it adheres to a fabric made of natural or synthetic fiber material (dyed fabric or non-fixed fabric) / Or pressurizing / heating It is found that processing of white discharge method, colored discharge method, white anti-discharge method and / or anti-color discharge method can be constructed by wet heat treatment by steaming etc. Finally, the present invention has been completed.

The characteristics of the present invention are as follows. Various auxiliary agents necessary for a one-phase dry transfer printing method, such as an ink receiving layer to be applied on a release agent layer, (1) softened or melted by heat on paper Hydrophilic synthetic resin that can transfer chemicals (which may contain coloring materials) onto the cloth, (2) Low-temperature softening foil transfer binder paste (nylon powder etc. as the main component to shorten the transfer time if necessary, (3) Insertion color material, color removal agent, and anti-dyeing agent (4) Moisturizing agent for promoting the diffusion / penetration of ink into the fiber and the anti-discharge / discharge effect (5) ) The all-in-one system is equipped with the optimal amount that can be used for each effect, such as hydrophilic glue to keep the pattern sharp on the paper. This eliminates the complication of the printing work and reproducibility. Prevention and discharge characterized by a rational approach Which is a dry transfer printing method.

The required amounts of various auxiliary agents and chemicals for these ink receiving layers of the present invention are 10-30 wt% of hydrophilic synthetic resin, 0-30 wt% of foil transfer binder paste, 5-20 wt. %, Humectant 0 to 15% by weight, hydrophilic paste 0.5 to 10% by weight and the remainder (% by weight) are preferably used in the range of water.

Further, in order to improve the physical properties of the ink receiving layer, as various auxiliary agents added as necessary, a surface tension reducing agent for preventing water repellency at the time of coating, for example, 0.1 to 3% by weight of an anionic surfactant, Moreover, 0.5 to 5 weight% etc. of acrylic acid-type synthetic glues can be arbitrarily used for the increase in the viscosity of the paste solution at the time of coating.

Another feature of the present invention is that the ink containing an anti-discharge agent (including a color material as necessary) is a water-soluble or water-dispersed discharge agent, a color remover, an anti-dyeing agent, a stabilizer or, if necessary, a colorant. The ink receiving layer formed on the release agent layer is mainly composed of two components, which includes a hydrophilic synthetic resin that is softened or melted by heat, a hydrophilic paste, A transfer paper is prepared by applying and drying the mixed glue solution, and ink containing an anti-discharge agent (including color material if necessary) is applied to the transfer paper by ink jet printing or other methods to form a transfer paper. A dry transfer printing method for preventing and discharging, characterized in that a paper is used for transfer printing on a fabric made of a natural or synthetic fiber material.

In this case, a coating method in which a large amount of hydrophilic paste is in direct contact with the release agent layer, for example, a water-soluble (hydrophilic) synthetic resin and a large amount of water-soluble (hydrophilic) paste are mixed. Under conditions such as use, the ability to peel off water-soluble (hydrophilic) synthetic resins by heating and pressurization is greatly reduced, which may result in lack of transferability and transfer reproducibility of ink to the fabric. When the transfer paper prepared with the two-layer structure of the present invention is used, there is an advantage that such an adverse effect can be suppressed. In addition, when using reactive dyes or reducing agents as water-soluble or water-insoluble dressing / extracting / anti-dyeing agents, if the transfer paper does not contain alkali agents, natural fiber materials should be used with alkali agents, moisturizers, and other necessary It is necessary to pre-process with materials.

In this case, the transfer force is greatly reduced under coating conditions in which a large amount of hydrophilic paste is in direct contact with the release agent layer. In order to prevent this, the present invention also includes a method for forming a two-layer ink-receiving layer in which a paste is applied after applying a resin as an ink-receiving layer. A method of making the ink receiving layer one layer by selecting and adjusting the ratio has been found, and more preferably, the object of the present invention has been achieved.

In order to improve the physical properties of the ink receiving agent, as an auxiliary agent added as necessary, a surface tension reducing agent for preventing water repellency during coating, for example, an anionic surfactant 0.1 to 3%, an ink receiving layer In addition, wetting and moisturizing agents such as polyethylene glycol (MW 200-600) 1-5% or glycerin 1-3% for improving the adhesive strength of the film after dye printing are also used to increase the viscosity of the paste solution during coating. Can arbitrarily use 0.5 to 3% acrylic acid synthetic paste. Furthermore, for the purpose of shortening the transfer time, a foil transfer binder mainly composed of nylon powder or acrylic resin can be added.

The materials used to make inks containing these anti-discharge / discharging agents (including coloring materials if necessary) are water-soluble compounds that are dissolved in water to form inks. In the case of water-dispersible compounds, an appropriate amount of dispersant is added. To make ink.

For example, in the case of reactive dyes, it is preferable to select from among the reactive dyes that can withstand stannous reducing agents. As the marking agent for coloring and checking the printed state of the pattern, a colorant that is reduction resistant and does not stain the target fiber material is selected.

Inks containing these anti-discharge agents (including color materials if necessary) are additives that take into account both sides of the drying resistance of the printing machine nozzle (clogging prevention) and the drying properties of the chemicals printed on the transfer paper. It is desirable to prepare by adding. That is, glycols such as ethylene glycol, diethylene glycol, triethylene glycol, and polyethylene glycol MW 200 to 600 are used as a drying inhibitor that also improves drug solubility, and sequestering agents such as ethylenediaminetetraacetic acid. 0.1% to 0.5% of disodium salt, sodium hexametaphosphate, etc., 0% of antiseptic / antifungal agents such as benzimidazole, sodium benzoate, organic iodine, organic sulfur, organic nitrogen sulfur Add 0.05-0.5% and adjust the concentration and pH with ion-exchanged water (PH = 7 ± 1).

Next, the ink liquid is preferably filtered by a known method and provided as an ink containing an anti-discharge agent (including a color material if necessary). The transfer paper is prepared by printing the ink prepared as described above on the transfer paper composed of the above-mentioned transfer paper, that is, the transfer paper-ink acceptor layer, by ink-jet printing or other methods and drying.

The method of the present invention mainly describes the use of a high-tech ink jet printing machine, but by adjusting the viscosity of the ink with a glue, it can be used in various ways such as mechanical printing, hand printing, hand drawing, printing, etc. It goes without saying that colors can be added. If you draw a design using ancient Japanese dyeing techniques such as hand-drawn Yuzen, you can make it into an artistic sewing product that has only one in the world.

Next, the transfer paper is matched with a fabric made of natural or synthetic fiber material, and the ink receiving layer and the drug layer are transferred to the fabric by pressurization and heating by 90% or more, preferably about 100%, particularly preferably 100%. After that, the ground dye is disassembled and / or fixed, and the resin, chemicals, and paste used as the ink receiving layer are removed by washing (washing, soaping, washing), and the fabric has a good fiber texture. Obtain a printed fabric or printed sewing product.

In the present invention, after the transfer to the fabric, the fixing condition employed in the normal direct printing method can be used as it is for the decomposition and / or fixing treatment of the ground dye. After the dye fixing treatment, the synthetic resin and paste used for the ink receiving layer are removed by a conventional washing condition (water washing, soaping, water washing) to obtain a printed matter having a good fiber texture.
In addition, since the transfer paper that has been transferred can be recycled as the base paper for transfer, and the amount of glue attached is small, considering that the waste water load on the washing water of the transfer fabric is also small, the method of the present invention is environmentally friendly. It can be said that it is eco-friendly and gentle to the environment.

In the printing of reactive dyes, in the mixed system where dye-water-alkali coexists, the dye tends to be hydrolyzed, resulting in poor dyeing. However, there is no moisture on the one-phase transfer paper, which may cause hydrolysis. There is a feature that is relaxed. However, a moisturizing agent that allows both dye and alkali to permeate and diffuse into the fiber is indispensable for dyeing the fabric. However, when dye solution is printed on transfer paper containing moisturizing agent, The moisturizing agent has a deliquescent property, and the dye bleeds, and there is a problem that a delicate design cannot be expressed.

In addition, contradictory physical properties that are considered difficult to achieve compatibility, for example, the adhesion and release properties of dyes on transfer paper are contradictory. When the peelability is improved and the peelability is improved, the transferability is good, but the stability of the transfer paper is deteriorated, which causes a problem in storage of the transfer paper.

The present inventors repeated persistent research and experiments, and included many difficult problems such as transferability, transfer paper stability, print design sharpness, dyeing power, cleanability, and fiber texture in the ink receptor composition. In combination with the selection and optimization of various chemicals, we found a solution by adjusting the compositional balance of multiple components.As a result, the pretreatment of the fabric can be omitted, which is not only industrially advantageous, The company has developed a new technology with a high practical value that can be adopted by ordinary households.

In addition, various water-soluble and water-insoluble dyes are applied to the dry transfer printing method for preventing and discharging according to the present invention. In addition to reactive dyes, water-soluble dyes are also applicable to acid dyes, metal complex dyes, and direct dyes. For example, in prevention and discharge using reactive dyes as ground dyes, VS reactive dyes and 3-15% by weight of sodium carbonate, potassium carbonate, sodium bicarbonate, sodium silicate, sodium trichloroacetate, etc. as transfer agents, and yellow at the time of transfer. Pads are dried with a mixture of 3 to 25% by weight of urea and 0.05 to 1% by weight of a hydrophilic thickener such as sodium alginate as a migration inhibitor for the purpose of preventing alteration, improving transferability, and improving dyeing. . In addition, when acid dyes are used as background dyes, 0.5-5% by weight of acid ammonium salts such as ammonium sulfate, ammonium nitrate, ammonium tartrate, etc. as migration dyes and pH adjusters (dyeing accelerators), preventing migration Pad and dry a 0.05-0.5 wt% mixture of acid resistant natural gums as an agent.

For fixing the dye to the fiber after the transfer, the fixing conditions employed in the normal direct printing method can be used as they are. In the case of non-fixed fabric, for example, in the one-phase steam fixing method of reactive dyes, the steaming treatment is performed at 100 to 105 ° C. for 10 to 30 minutes with acidic dyes, such as the steaming treatment at 100 to 105 ° C. for 5 to 20 minutes. Do. After the dye fixing treatment, the synthetic resin and paste used for the ink receiving layer are removed by a conventional washing condition (water washing, soaping, water washing) to obtain a printed matter having a good fiber texture.
