[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a textile printing method. [Prior Art] In addition to roll printing and screen printing, conventional printing methods include pure printing as shown in British Patent No. 647105, French Patent No. 1223330, Japanese Patent No. 415613, and Japanese Patent No. 440155.

There is a photosensitive printing method shown in the issue. Each of these conventional printing methods has the following serious drawbacks. In other words, roll printing and screen printing have the major drawback that it is almost impossible to print and reproduce delicate, graphic-like patterns and designs due to the use of rolls and screens. There is a large loss of dye during post-processing such as soaping and water washing, which tends to cause fabric stains and water pollution. Although it is possible to express fine graphic patterns and designs with pure dry transfer printing, it is limited to synthetic fibers such as polyester and acetate, and is not possible with natural fibers. In addition, in the case of synthetic fibers, the texture is poor and phenomena such as pewter peeling are likely to occur. In wet transfer printing, there are no restrictions on the type of fabric, but since it uses water-soluble dyes, lithographic printing is impossible, and if you want to obtain minute patterns and designs like photographs, you have to rely on gravure printing. However, it is extremely uneconomical to produce printed products in small lots and in many varieties, and is not suitable for industrial implementation. In addition, although the photosensitive printing method can overcome the above-mentioned disadvantages of the printing method, it involves many manual elements and the process is extremely complicated, making it impossible to obtain printed products quickly and easily. [Purpose of the Invention] The present inventor has been researching textile printing methods for a long time, and in this research, he has solved the problems of each of the conventional textile printing methods and created fine, graphic-like patterns and designs. We have continued our intensive research with the aim of developing an economical and easily reproducible printing method for a wide range of fabrics, both natural fibers and synthetic fibers. In this research, he came up with the idea of printing without using gravure printing using lithographic inks or water-soluble dyes that could not be used at all in lithographic printing, and continued research based on this idea. As a result, by using an ink obtained by kneading a pigment obtained by subjecting a water-soluble dye to a water-insolubilizing treatment or a lipophilic treatment and kneading it with a lithographic ink vehicle, the above-mentioned intended purpose can be almost achieved. I found out. The present inventor further continued research into this new fact, and found that when using this new ink and also using a specific coating agent, the color tone of the printed product obtained will be even deeper and more colorful. This discovery led us to complete the present invention. That is, the present invention provides a textile printing method in which lithographic direct printing or lithographic offset printing is performed on the surface of a fabric, and then post-treatments such as steaming, soaping, and water washing are carried out. Alternatively, a product prepared by subjecting this to a lipophilic treatment and then kneading it with a lithographic ink vehicle can be used, and (b) this resin can be dissolved in an alcohol-soluble and water-insoluble resin. A textile printing method characterized by using a coating agent containing a base component consisting of a solvent and at least one selected from the group of solubilizers, surfactants, alkaline substances, neutral soda salts, and water. surfactant,
The present invention relates to a printing method characterized by using a coating agent containing at least one selected from the group of alkaline substances, neutral soda salts, and water. [Operation of the Invention] According to the method of the present invention, all the drawbacks of conventional textile printing methods can be overcome. That is, in the method of the present invention, water-soluble dyes such as direct dyes, reactive dyes, acid dyes, acidic metal-containing dyes, basic dyes, etc. are insolubilized to give them properties as pigments, and then used as a vehicle for ordinary lithographic inks. By kneading, direct lithographic printing or lithographic offset printing is possible, and delicate patterns and designs can be easily and economically reproduced on both natural fiber and synthetic fiber fabrics.
Furthermore, since it does not rely on gravure printing, it can be economically and quickly adapted to the production of small lots and a wide variety of products. In addition, when making a water-soluble material water-insolubilized, by using both water-insolubilization treatment and lipophilic treatment, it is possible to improve the wettability of the water-insolubilized material with the oil-based vehicle for lithographic printing, improve the leveling and transferability of the ink, and darken the color. This makes it possible to achieve even dyeing. Another noteworthy feature of the present invention is that the above-mentioned printing and textile printing are performed in combination with the above-mentioned coating agent. As is well known, lithographic printing is one of the four major printing methods used industrially, along with gravure, letterpress (or letterpress), and silk screen printing. Of all these methods, lithographic printing requires the most ink. Print film thickness is thin. For this reason, there is the fateful drawback that it is difficult to obtain rich, colorful tones. However, in the present invention, a coating agent containing at least one of the above-mentioned specific components, ie, a solubilizer, an alkaline substance, a surfactant, a neutral soda salt, and water, is combined with the above-mentioned specific ink. By performing printing and textile printing in combination, the once insolubilized dye is efficiently restored to a soluble state during steaming, and the effect of dyeing the fabric is exhibited. As a result, extremely rich and colorful colors can be obtained. Furthermore, by applying this coating agent, the oil-based lithographic ink vehicle that has adhered to the fabric can be easily removed by soaping, washing with water, or the like. This makes it easier to perform the process equivalent to de-sizing in general textile printing. Another advantage is that, although it is water-based, it can be lithographically printed. This means that there is no need to separately prepare a coating machine, and printing can be completed in one step using a lithographic multicolor printing machine, which is extremely efficient and economical. Furthermore, since the coating agent is water-based, water can be used to clean the printing press after printing, making the process extremely efficient and sanitary. [Structure of the Invention] The ink used in the method of the present invention is produced by subjecting a water-soluble dye to water-insolubilizing treatment or lipophilic treatment and kneading this with a lithographic ink vehicle. be. There are various types of water-soluble dyes used in this case, including direct dyes, reactive dyes, acid dyes, acidic metal-containing dyes, and basic dyes, all of which can be used effectively in a wide range of applications. The treatment for making these water-soluble dyes water-insoluble is not particularly limited as long as it is a means that can make the dye water-insoluble, but representative methods are as follows. (i) Metal salts or insoluble salts by chelation (ii) Soaking into insoluble amine salts (iii) Physical adsorption onto adsorbents (iv) Coagulation (v) Combination of the above treatments Please explain in more detail. The example is as follows. The method (i) using metal salts or chelation is a method in which the dye is made water-insoluble by converting it into a metal salt or by chelating it, and the metal compound used is a metal compound, especially an inorganic compound. Compounds are preferred, and specific examples include halogen compounds of various metals, such as Na, Fe, Ca, Al, etc., sulfides, and oxides of Si, Ti, etc. as preferred examples. Furthermore, various chelating agents capable of chelating dyes can be widely used as the chelating agents used at this time. The conditions for insolubilization are not particularly limited, and conditions that produce a metal salt or chelate may be appropriately adopted. In order to obtain the insoluble amine salt (ii), a nitrogen-containing organic compound is usually dissolved in a water-soluble organic solvent as required in an aqueous solution of a water-soluble dye, and the mixture is added and mixed at room temperature or under heating. The solvent at this time may be any water-soluble organic solvent, and examples thereof include various alcohols. Next, the insolubilized product can be obtained by filtering, washing and drying the above mixture. The organic nitrogen-containing compounds used to make these water-soluble dyes water-insoluble include not only aliphatic compounds but also aromatic compounds. For example, amines and amides are representative examples of aliphatic compounds. For example, the former includes primary, secondary, and tertiary amines, and specific examples include various alkyl amines such as 1-aminododecane, N-tetradecylamine, palmitylamine, and stearylamine. Examples of the latter amides include various fatty acid amides, and specific examples include oleic acid amide, ricinoleic acid amide, stearic acid amide, and the like. Representative examples of the aromatic compound include various aromatic amines and various aromatic amides, and specific examples include phenylenediamine, diphenylguanidine, and the like. Among these compounds, 1-aminododecane, o-phenylenediamine, and oleic acid amide can be exemplified as preferred. Examples of the method (iii) of adsorption to an adsorbent and the method of coagulation (iv) include a method using the cohesive force of a condensate of benzaldehyde and a polyhydric alcohol, a method using zirconium complexes, carbon racks, activated carbon, etc. Preferred specific examples include methods that utilize the adsorption ability of porous adsorbents such as graphite and γ-alumina. These water insolubilization treatments are appropriately selected and used depending on the type of dye used, printing conditions, etc. Furthermore, the present invention includes not only a water insolubilization treatment but also a combination of this and a lipophilization treatment. At this time, water insolubilization treatment may be performed in advance and then lipophilization treatment may be performed, or conversely, lipophilization treatment may be performed and then water insolubilization treatment may be performed. As the lipophilic treatment at this time, a method of treatment with a metal compound can be exemplified. This treatment using a metal compound is the same as the method (i) of the above-mentioned water insolubilization treatment to form a metal salt.In other words, the water insolubilization method to form a metal salt (i) At the same time, it can be said that it also has the effect of making it lipophilic. In the present invention, it is essential to use a coating agent. This coating agent may be applied to the fabric in advance as a so-called undercoat when printing or textile printing is performed using the above-mentioned ink, or may be applied as a so-called overcoat after printing with the ink. Furthermore, an undercoat and an overcoat may be used together. When used in combination, two different coating agents can be used, and the coating agent can be printed twice to increase the film thickness. The point is, you just need to use different ink colors depending on the number of ink colors and the number of printing press units. The coating agent used at this time consists of a base component consisting of an alcohol-soluble and water-insoluble resin and a solvent capable of dissolving this resin, a dye solubilizer, a surfactant, an alkaline substance, a neutral soda salt, and water. It is made by blending at least one member selected from the group consisting of: As the resin used as the base component, alcohol-soluble and water-insoluble resins are widely used from a range of natural or synthetic resins, but preferred ones include rosin-modified maleic acid resin, rosin-modified phenolic resin, and rosin-modified fumaric acid resin. Examples include resins, and various glycols as solvents that can dissolve these resins. The most preferred base component is a so-called moisture set type varnish, particularly a varnish consisting of a rosin-modified maleic acid resin with a high acid value and a glycol. The ratio of the base component resin to the solvent is not particularly limited and can be appropriately determined from a wide range. Dye solubilizers to be added to this base component include polyhydric alcohols such as diethylene glycol, thiodiethylene glycol, mono-, di-, or tri-ethanolamine glycerin, glycerin acetate esters such as acetin, diethylene glycol monoalkyl ethers (alkyl Specific examples include ethers such as lower alkyl (preferably lower alkyl, specifically ethyl), triglycol alkyl ether (alkyl is the same as above), urea, etc., and are generally referred to as dye solubilizers or hydrotrobing agents. things are used. Of these,
In particular, diethylene glycol is most desirable. In addition, when using glycols as a base component in the present invention, this solubilizer may be omitted depending on the case. That is, when glycols are contained in an amount greater than that normally used as a base component, the excess glycol may act as a solubilizer in the present invention. Cationic, anionic, and nonionic surfactants are all included in the present invention, and particularly preferred are sodium stearate, sodium lauryl sulfate, and
Anionic activators such as sodium alkylbenzene sulfonate. Examples of the alkaline substance include morpholine, ammonia, KOH, NaOH, sodium chloride, soda carbonate, and water glass. Also, the term "soda salt" as used herein refers to a neutral salt, such as anhydrous nitric acid or crystalline sodium sulfate (Na ₂ SO ₄ .10H ₂ O). These are indispensable as alkali solubilization aids, especially for reactive dyes. One or more of these substances are blended into the base component, and the amount used in this case is usually about 10 to 150 parts by weight, preferably about 30 to 120 parts by weight, per 100 parts by weight of the base component. . As the lithographic ink vehicle used in the present invention, a wide range of vehicles that have been conventionally used for this type of lithographic ink can be used as they are, such as rosin, rosin-modified phenolic resin, alkyd resin, and oil-soluble acrylic. resin,
Any resin that can be used as a lithographic vehicle, such as petroleum resin, or a varnish consisting only of a natural drying vegetable oil such as tung oil or linseed oil or a synthetic drying oil without resin can also be used. In addition, the present invention does not preclude the addition of other usual additives used in lithographic inks, such as thickeners, thickening agents, gelling agents, dryers, tokinis, anti-back transfer agents, etc. I can give an example. In the present invention, an ink is prepared using this lithographic vehicle and the water-insolubilized product of the above-mentioned water-soluble dye according to a conventional method. In this case, the ink and the means used may be in accordance with conventional methods. The ink thus obtained is used to perform lithographic direct printing or lithographic offset printing on the surface of the fabric. In this case, not only synthetic resins but also natural fibers can be used as fabrics. For example, synthetic fibers include various types of nylon, polyester, acrylic, and various other synthetic fibers, and natural fibers include cotton, silk,
Examples include hemp and wool. Any of the conventional methods such as lithographic direct printing or lithographic offset printing can be effectively used. In addition, when undercoating with a coating agent, the coating agent is coated on the fabric prior to the above-mentioned printing. The thus printed fabric is dried with or without coating with a coating agent. This drying is preferably dry to the touch or completely dry. This is then followed by the usual steaming, soaping and rinsing. [Effects of the Invention] By the method of the present invention, all of the above-mentioned difficulties of conventional textile printing methods can be overcome. That is, (a) it becomes possible to form minute patterns and designs similar to color photographs. (b) It is possible to economically, quickly, and easily obtain printed products in small lots and in many varieties. (c) It can be applied to all kinds of fabrics, and can be applied not only to various synthetic fibers but also to various natural fibers. (d) Undesirable phenomena such as water pollution, white field pollution, and dye loss hardly occur. (E) It has excellent texture and various fastness properties, and there is no need to worry about so-called pewter peeling. (F) Furthermore, by using a coating agent in combination with the ink of the present invention, it is possible to obtain a print with an even more excellent deep and colorful tone, and the oil-based varnish in the ink can be easily removed. (g) Since the dye is insolubilized, there is very little dye-colored wastewater generated during post-treatments such as steaming, soaping, and washing, which is very useful for preventing water pollution. (H) The problem of white area contamination often seen in general textile printing hardly occurs in the present invention. [Example] The method of the present invention will be explained below with reference to Examples.

Example 2 A Insolubilization (oleophilization) treatment of dye and production of ink

[Table] With the formulations in Table 2 above, sufficient insolubilization treatment is possible even if the mixing of the second liquid is omitted, but red and blue can be treated by mixing the second liquid to further improve water resistance during printing. (moisture and water resistance) is further improved. The reaction and insolubilization treatment was conducted in accordance with Example 1. Using the thus obtained insolubilized (oleophilized) products of the four colors, ink is produced using the same formulation and method as in Example 1. B.

A printed product is obtained by steaming, soaping, washing, etc. The print thus obtained was strong, dark, and had a bright pink color. Example 4 Insolubilization treatment is carried out using reactive dyes as shown in the table below. The treatment method is exactly the same as that of Examples 1 to 3.

The three types of red ink and coating material in this example were printed and overprinted separately on silk, nylon, and wool fabrics using a lithographic offset printing machine. Teaming, soaping and washing are performed.
The resulting print forms a very colorful red graphic-like pattern on the fabric. Example 7 An acidic metal-containing dye is treated to be insolubilized (lipophilized) as shown in the table below.

[Table] The processing methods for the first liquid and the second liquid are the same as in Examples 1 to 6. Using the above-mentioned insolubilized dye, the same formulation as in Examples 1 to 6 was used, and the mixture was kneaded with three rolls to obtain four colors of ink. Using these four colors of ink, a color photograph of a landscape is printed on the surface of a wool fabric using a lithographic offset printing machine, and then the coating agent used in Example 6 is overprinted using the same machine. After drying, post-treatments such as steaming, soaping, and water washing yield a printed product with a delicate graphic pattern. Example 8 Insolubilization (lipophilization) treatment is performed using a direct dye as shown in Table 9.

[Table] For the second liquid Soccinol D (diphenylguanidine, Sumitomo Chemical)...5 Ethanol...10 Hydrochloric acid...3 Mix the second liquid with the first liquid of each color, stir and react, then filter and wash. A dye insolubilized (lipophilized) product is obtained by drying the residue. Ink was made from these dye-treated products using the same formulation and method as in Examples 1 to 7, and a photographic floral pattern was printed on cotton cloth with these four color inks using a lithographic offset printing machine. Overcoat with the coating agent used in Example 5. If both the ink and coating agent are dried and then subjected to post-treatments such as steaming, soaping, and water washing, a print with a deep color, bright color, and strong texture can be obtained. Example 9 The same results as in Example 8 were obtained by overcoating with the coating agents used in Examples 4 and 6 instead of the coating agent used in Example 8. Example 10 Even if the ink and coating agent used in Examples 8 and 9 were undercoated on a white cotton cloth before ink printing, Examples 8 to 9 were obtained.
The same result was obtained. Example 11 Examples 8 to 10 were also carried out using the so-called ink sanderch method in which the inks and coating agents used in Examples 8 to 10 were first undercoated with the latter, the former ink was printed, and then the coating agent was overcoated.
Similar results were obtained as in 10. Example 12 A dye is made insolubilizable (lipophilic) using the formulation shown in Table 10.

[Table] The first liquid and the second liquid are treated in the same manner as in Examples 1-11. Using this treated product, ink was prepared using the same formulation and method as in Examples 1 to 11. This ink and the coating agent used in Example 5 are printed on cotton cloth and nylon cloth using a lithographic printing machine. After drying, post-treatment of steaming, soaping and washing gives a graphic yellow print. Similar results were obtained with undercoat, overcoat, and sandwich coatings. Example 13 An ink is prepared using a commercially available basic dye lake according to the following formulation. Pink6G-RP (basic dye lake, Noma Chemical)
...1.2 Super gloss medium (Dainippon Ink) ...1.8 Linseed oil varnish ...0.4 Extra varnish ...0.2 This mixture is milled in a three-roll mill to make ink. This ink and the coating agent used in Example 5 were used to perform lithographic offset printing on cotton and nylon fabrics, followed by post-treatments such as steaming, soaping, and washing with water. When the coating agent was used as an undercoat, an overcoat, or a sandwich, clear graphic-like prints were obtained on both cotton and nylon fabrics. Example 14 A direct dye was agglomerated with a condensate of benzaldehyde and polyhydric alcohol. Make ink using commercially available lake pigment (insolubilized material). An ink was prepared by kneading the following formulation in three rolls. Direct black aggregate (EC Chemical)
...0.6 Super gloss medium (Dainippon Ink) ...1.4 Linseed oil varnish ...0.4 Special varnish ...0.1 This ink and the coating agent used in Example 5 were used for lithographic offset printing on cotton cloth and linen cloth, and after drying, Teaming, soaping and washing are performed. Regardless of whether the coating agent was an undercoat, an overcoat, or a sandwich, a deep dark green gradation pattern was formed on the fabric. Example 15 In Example 3, the components of the coating agent were changed to those shown in Table 11 below, and the other conditions were the same as in Example 3 to obtain a printed product, and its color tone was observed. However, in this example, for comparison, the color tone of a printed product obtained by using no coating agent at all and otherwise performing the same treatment as in this example was also observed.
