Description

[Technical field]

[0001] The present invention relates to a recording method and a recording apparatus. [Background technology]

[0002] Inkjet printers have become widespread in general households as digital signal output devices due to their advantages of low noise, low running costs, easy color printing, etc. In recent years, inkjet printers have been used not only for home use but also for industrial purposes such as displays, posters, and bulletin boards.

[0003] In the textile printing field, the market size of the so-called DTG (Direct to Garment) field, which prints directly on clothing such as T-shirts, is expanding year by year. In addition, due to trends such as the recent rise of the personal recommendation business in the apparel industry and the active collaboration with fine art in the interior textile field, there is an increasing demand for inkjet recording systems that can form images with excellent color development and various fastness properties on fabrics.

[0004] The textile printing method, which uses ink containing pigment as a coloring material to directly print images on fabric using inkjet printing, is different from screen printing and other conventional textile printing in that it does not require plate-related matters such as plate creation, storage, and cleaning, and has the advantages of being suitable for small-lot, high-mix production, enabling short delivery times as it does not involve a transfer process, and having excellent light resistance. For this reason, various studies have been conducted on pigment printing to improve the color development and fastness of printed matter, but it is difficult to satisfy these characteristics with ink alone, and in recent years, a method has been proposed in which the fabric is pretreated before the ink is printed on the fabric.

[0005] Patent Document 1 discloses a method for producing a printed textile, the method including: a first step of applying to a cloth a first pretreatment liquid containing at least water and an ink coagulant; a second step of applying to the cloth a second pretreatment liquid having a smaller ink coagulation power than the first pretreatment liquid; and a third step of inkjet printing on the cloth using an aqueous inkjet ink.

[0006] Patent Document 2 discloses a pretreatment liquid used in inkjet pigment printing, which contains at least one of a resin dispersion and a crosslinking agent, a lubricant, and water. Summary of the Invention [Problem to be solved by the invention]

[0007] However, there is a problem in that it is difficult to achieve both the storage stability of the treatment liquid that is applied in advance to the fabric to which the ink is applied, and the flexibility of the printed matter formed using the treatment liquid and the ink. [Means for solving the problem]

[0008] The present invention relates to a recording method including a first treatment liquid application step of applying a first treatment liquid to a fabric, a second treatment liquid application step of applying a second treatment liquid to the fabric, and an ink application step of applying ink to an area of ​​the fabric to which the first treatment liquid and the second treatment liquid have been applied, wherein the first treatment liquid includes water and a lubricant, and the second treatment liquid includes water and a coagulant. Effect of the Invention

[0009] According to the present invention, it is possible to provide a recording method that improves both the storage stability of the treatment liquid that is applied in advance to the fabric to which the ink is applied, and the flexibility of the printed matter formed using the treatment liquid and the ink. [Brief description of the drawings]

[0010] [Figure 1] FIG. 1 is a schematic diagram showing an example of a recording apparatus. [Diagram 2] FIG. 2 is a schematic diagram showing an example of the container means. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, one embodiment of the present invention will be described.

[0012] <<Recording method>> The recording method of the present invention includes a first treatment liquid application step of applying a first treatment liquid to a fabric, a second treatment liquid application step of applying a second treatment liquid to the fabric, and an ink application step of applying ink to the area of ​​the fabric to which the first treatment liquid and the second treatment liquid have been applied. The recording method of the present invention may also include other steps as necessary. In the present disclosure, the "first treatment liquid" and the "second treatment liquid" are liquid compositions that are applied in advance to the fabric before the ink is applied. In the present disclosure, an "ink" is a liquid composition that forms an image by being applied to an area of ​​a fabric to which the first treatment liquid and the second treatment liquid have been applied.

[0013] <First treatment liquid application step> The first treatment liquid application step is a step of applying the first treatment liquid to the fabric. The method of applying the first treatment liquid is not particularly limited, and examples thereof include an inkjet method, a blade coating method, a gravure coating method, a bar coating method, a roll coating method, a dip coating method, a curtain coating method, a slide coating method, a die coating method, and a spray coating method. Among these, a step of discharging the first treatment liquid onto the fabric by an inkjet method is preferable. As described below, the first treatment liquid used in the recording method of the present disclosure is unlikely to undergo viscosity changes and has excellent storage stability, so that it can be suitably applied even to an inkjet method in which the discharge performance is strongly affected by viscosity, etc.

[0014] -First processing solution- The first treatment liquid contains a lubricant and water, and may further contain an organic solvent, a surfactant, and other components, as necessary.

[0015] --Lubricant-- The lubricant refers to a component that has the function of improving the fastness and flexibility of a printed matter when contained as a component constituting the printed matter. By including a lubricant in the first treatment liquid, the fastness and flexibility of the printed matter formed by applying the first treatment liquid or the like can be improved.

[0016] The lubricant is preferably an anionic compound or a nonionic compound from the viewpoint of suppressing contamination of the inside of the device by mist generated when the first treatment liquid is applied to the fabric. Note that, since the generation of mist becomes prominent when the first treatment liquid is ejected by an inkjet method, it is more preferable to use an anionic compound or a nonionic compound in such a case.

[0017] Examples of the lubricant include siloxane compounds and waxes. Among these, siloxane compounds are preferred from the viewpoint of further improving the fastness and flexibility of the printed matter.

[0018] The siloxane compound is not particularly limited and can be appropriately selected according to the purpose, and examples thereof include organopolysiloxanes such as dimethylpolysiloxane, and modified organopolysiloxanes such as polyether-modified organopolysiloxanes, amino-modified organopolysiloxanes, hydroxy-modified organopolysiloxanes, epoxy-modified organopolysiloxanes, and phenyl-modified organopolysiloxanes. Among these, it is preferable to use dimethylpolysiloxane or amino-modified organopolysiloxane from the viewpoint of further improving the dry friction fastness and flexibility of the printed matter. These may be used alone or in combination of two or more.

[0019] Commercially available siloxane compounds include, for example, dimethylpolysiloxane (trade name: KM-860A, manufactured by Shin-Etsu Chemical Co., Ltd.), dimethylpolysiloxane (trade name: KM-9737A, manufactured by Shin-Etsu Chemical Co., Ltd.), dimethylpolysiloxane (trade name: KM-9782, manufactured by Shin-Etsu Chemical Co., Ltd.), dimethylpolysiloxane (trade name: KM-862T, manufactured by Shin-Etsu Chemical Co., Ltd.), dimethylpolysiloxane (trade name: KM-9738A, manufactured by Shin-Etsu Chemical Co., Ltd.), amino-modified organopolysiloxane (trade name: POLON-MF-14, manufactured by Shin-Etsu Chemical Co., Ltd.), amino-modified organopolysiloxane (trade name: POLON-MF-14, manufactured by Shin-Etsu Chemical Co., Ltd.), Examples of such organopolysiloxanes include siloxane (trade name: POLON-MF-51, manufactured by Shin-Etsu Chemical Co., Ltd.), epoxy-modified organopolysiloxane (trade name: X-51-1264, manufactured by Shin-Etsu Chemical Co., Ltd.), phenyl-modified organopolysiloxane (trade name: KM-9739, manufactured by Shin-Etsu Chemical Co., Ltd.), polyether-modified organopolysiloxane (trade name: BYK-307, manufactured by BYK Japan Co., Ltd.), dimethylpolysiloxane (trade name: BYK-333, manufactured by BYK Japan Co., Ltd.), and dimethylpolysiloxane (trade name: BYK-378, manufactured by BYK Japan Co., Ltd.).

[0020] The wax is not particularly limited and can be appropriately selected depending on the purpose, but from the viewpoint of further improving the fastness and flexibility of the printed matter, for example, polyethylene wax, carnauba wax, etc. These may be used alone or in combination of two or more kinds.

[0021] As the polyethylene wax, commercially available products can be used, such as the Nopcoat series manufactured by San Nopco Ltd., the Nopcomaru series manufactured by San Nopco Ltd., the Hi-Tech series manufactured by Toho Chemical Industry Co., Ltd., and the AQUACER series manufactured by BYK-Chemie Japan K.K.

[0023] The melting point of the wax is preferably from 50° C. to 130° C., and more preferably from 60° C. to 120° C. When the melting point is in the above range, the fastness and flexibility of the printed matter can be further improved.

[0024] The lubricant is preferably contained in the first treatment liquid in the form of lubricant particles, in other words, in a dispersed state. By stably maintaining the form of the lubricant particles in the first treatment liquid, the viscosity change in the first treatment liquid is suppressed, the storage stability is improved, and the first treatment liquid can be suitably applied even to an inkjet method in which the ejection performance is strongly affected by the viscosity, etc. The lubricant constituting the lubricant particles may be liquid or solid. The volume average particle diameter of the lubricant is not particularly limited and can be appropriately selected according to the purpose, but is preferably 0.01 μm or more, more preferably 0.01 μm or more and 0.2 μm or less. If the volume average particle diameter is 0.01 μm or more, the flexibility of the printed matter can be further improved. The volume average particle diameter can be measured, for example, using a particle size analyzer (device name: Nanotrac Wave-UT151, manufactured by Microtrac Bell Co., Ltd.).

[0025] The content of the lubricant is preferably 0.1% by mass or more and 10.0% by mass or less, more preferably 0.1% by mass or more and 6.0% by mass or less, based on the mass of the first treatment liquid. When the content is 0.1% by mass or more, the flexibility of the printed matter can be further improved. Also, when the content is 10.0% by mass or less, the washing fastness of the printed matter is improved.

[0031] --Surfactant-- As the surfactant, for example, a silicone-based surfactant, a fluorine-based surfactant, an amphoteric surfactant, a nonionic surfactant, an anionic surfactant, etc. can be used, but a silicone-based surfactant is preferable from the viewpoint of further improving the flexibility of the printed matter when used in combination with a lubricant. Note that, unlike the lubricant, the surfactant is preferably contained in the first treatment liquid in a dissolved form.

[0032] The silicone surfactant is not particularly limited and can be appropriately selected according to the purpose. Among them, those that do not decompose even at high pH are preferable. Examples of silicone surfactants include side chain modified polydimethylsiloxane, both end modified polydimethylsiloxane, one end modified polydimethylsiloxane, and both end modified polydimethylsiloxane of side chain. Those having a polyoxyethylene group or a polyoxyethylene polyoxypropylene group as a modified group are particularly preferable because they show good properties as an aqueous surfactant. In addition, polyether modified silicone surfactants can also be used as silicone surfactants, and examples thereof include compounds in which a polyalkylene oxide structure is introduced into the Si part side chain of dimethylsiloxane.

[0033] As the fluorosurfactant, for example, perfluoroalkylsulfonic acid compounds, perfluoroalkyl carboxylic acid compounds, perfluoroalkyl phosphate compounds, perfluoroalkyl ethylene oxide adducts, and polyoxyalkylene ether polymer compounds having perfluoroalkyl ether groups in the side chain are particularly preferred because they have low foaming properties.

[0037] The silicone surfactant is not particularly limited and can be appropriately selected depending on the purpose. Examples of the silicone surfactant include side-chain modified polydimethylsiloxane, both-end modified polydimethylsiloxane, one-end modified polydimethylsiloxane, and both-end side-chain modified polydimethylsiloxane. Polyether-modified silicone surfactants having a polyoxyethylene group or a polyoxyethylene polyoxypropylene group as the modifying group are particularly preferred because they exhibit good properties as aqueous surfactants. Such surfactants may be appropriately synthesized or commercially available products, such as those available from BYK-Chemie Co., Ltd., Shin-Etsu Chemical Co., Ltd., Dow Corning Toray Silicone Co., Ltd., Nippon Emulsion Co., Ltd., and Kyoeisha Chemical Co., Ltd. The polyether-modified silicone surfactant is not particularly limited and can be appropriately selected depending on the purpose. For example, it can be a surfactant represented by the general formula (S-1) in which a polyalkylene oxide structure is introduced into the Si part side chain of dimethylpolysiloxane. [ka] (In the general formula (S-1), m, n, a, and b each independently represent an integer, R represents an alkylene group, and R' represents an alkyl group.)

Examples of the fluorine-based surfactant include perfluoroalkyl phosphate compounds, perfluoroalkyl ethylene oxide adducts, and polyoxyalkylene ether polymer compounds having perfluoroalkyl ether groups on the side chains. Among these, polyoxyalkylene ether polymer compounds having perfluoroalkyl ether groups in the side chains are preferred because they have low foaming properties, and in particular, fluorine-based surfactants represented by general formulas (F-1) and (F-2) are preferred. [ka] In the compound represented by the above general formula (F-1), m is preferably an integer of 0 to 10, and n is preferably an integer of 0 to 40 in order to impart water solubility.

[0040] The content of the surfactant in the first treatment liquid is not particularly limited and can be appropriately selected depending on the purpose. From the viewpoint of excellent wettability and ejection stability, however, the content is preferably 0.001% by mass or more and 5% by mass or less, and more preferably 0.05% by mass or more and 5% by mass or less.

[0041] --Other ingredients-- As other components, various known additives can be used as necessary, such as antifoaming agents, pH adjusters, antiseptic and antifungal agents, and rust inhibitors.

[0042] --Physical properties of the first processing solution-- The physical properties of the first treatment liquid are not particularly limited and may be appropriately selected depending on the purpose. For example, it is preferable that the viscosity, surface tension, pH, etc. are within the following ranges. The viscosity of the first treatment liquid at 25°C is preferably from 5 mPa·s to 30 mPa·s, more preferably from 5 mPa·s to 25 mPa·s, in order to obtain good dischargeability. Here, the viscosity can be measured using, for example, a rotational viscometer (RE-80L manufactured by Toki Sangyo Co., Ltd.). The measurement conditions are 25°C, a standard cone rotor (1°34' x R24), a sample liquid volume of 1.2 mL, a rotation speed of 50 rpm, and 3 minutes. The surface tension of the first treatment liquid is preferably 35 mN / m or less, and more preferably 32 mN / m or less at 25° C., in order to ensure good leveling on the fabric and shorten the drying time. The pH of the first treatment liquid is preferably from 7 to 12, and more preferably from 8 to 11, from the viewpoint of preventing corrosion of metal members that come into contact with the liquid.

[0043] <Second Processing Liquid Application Step> The second treatment liquid application step is a step of applying a second treatment liquid to the fabric. The order of the first treatment liquid application step and the second treatment liquid application step is not particularly limited, but from the viewpoint of improving the dry rub fastness of the printed matter, it is preferable to perform the second treatment liquid application step after the first treatment liquid application step. When the second treatment liquid application step is performed after the first treatment liquid application step, the first treatment liquid application step and the second treatment liquid application step may be performed consecutively without any other step being interposed between them, or the second treatment liquid application step may be performed after a step of drying the first treatment liquid applied in the first treatment liquid application step. The method of applying the second treatment liquid is not particularly limited, and examples thereof include an inkjet method, a blade coating method, a gravure coating method, a bar coating method, a roll coating method, a dip coating method, a curtain coating method, a slide coating method, a die coating method, and a spray coating method. Among these, a step of discharging the second treatment liquid onto the fabric by an inkjet method is preferable. As described below, the second treatment liquid used in the recording method of the present disclosure is unlikely to undergo viscosity changes and has excellent storage stability, so that it can be suitably applied even to an inkjet method in which the discharge performance is strongly affected by viscosity, etc.

[0044] -Second processing solution- The second treatment liquid contains a flocculant and water. The second treatment liquid may contain an organic solvent, a surfactant, and other components as necessary. Details (type, content, etc.) of the water, organic solvent, surfactant, and other components in the second treatment liquid are the same as those in the first treatment liquid described above, and therefore will not be described here. The physical properties of the second treatment liquid are also the same as those in the first treatment liquid described above, and therefore will not be described here.

[0045] --Flocculant-- The aggregating agent refers to a component that causes aggregation or thickening of the ink when it comes into contact with the ink. Specifically, for example, a component that causes aggregation of dispersible particles (mainly anionic compounds) such as coloring materials or resins contained in the ink can be mentioned. By using a second pretreatment liquid containing such an aggregating agent, aggregation or thickening occurs in the ink that comes into contact with the area to which the second pretreatment liquid is applied, and this makes it possible to retain ink components such as coloring materials on the surface of the fabric, thereby improving the image density of the printed matter.

[0046] In the present invention, the reason why the flocculant is contained in the second processing liquid and is used in two liquids independently of the first processing liquid containing a lubricant, in other words, the reason why a single processing liquid containing both a flocculant and a lubricant is not used will be explained. As described above, the flocculant is a component that aggregates anionic water-dispersible particles such as coloring materials or resins contained in the ink, and therefore is preferably a cationic compound. In this case, when the flocculant, which is a cationic compound, and the lubricant are allowed to coexist in the treatment liquid, the lubricant aggregates due to the flocculant, and the treatment liquid thickens. Therefore, from the viewpoint of long-term storage stability (storage stability), it is preferable that the flocculant and the lubricant are contained in separate treatment liquids and used in two liquids. In addition, the aggregation that occurs when the flocculant and the lubricant are allowed to coexist becomes prominent when the lubricant is an anionic compound, so from the viewpoint of increasing the effect (storage stability), it is preferable that the lubricant in the present invention is an anionic compound. From the above, it is preferable that the first treatment liquid contains a lubricant but does not substantially contain a flocculant, and the second treatment liquid contains a flocculant but does not substantially contain a lubricant. Note that "substantially free" is not limited to the case where a specific component is not contained, and may be within a range where the influence of the specific component is not caused, for example, when a specific component is analyzed by a method known and common technical knowledge, the specific component is below the detection limit. Furthermore, in the present invention, the first treatment liquid containing a lubricant and the second treatment liquid containing a flocculant are stored and applied independently, and therefore viscosity changes (thickening) are suppressed compared to a treatment liquid containing both a lubricant and a flocculant, making the present invention suitably applicable even to inkjet methods in which the ejection performance is strongly affected by viscosity, etc.

[0047] As the flocculant, for example, inorganic salts, organic salts, cationic polymers, etc. can be used. Among these, inorganic salts or organic salts are preferable from the viewpoint of material safety. From the viewpoint of washing fastness of the resulting printed matter, monovalent inorganic salts or organic salts are preferable, and from the viewpoint of image density, divalent or higher inorganic salts are preferable. These may be used alone or in combination of two or more.

[0048] Examples of inorganic salts include monovalent inorganic salts such as sodium chloride, potassium chloride, and potassium nitrate, and divalent or higher inorganic salts such as calcium carbonate, calcium nitrate, calcium chloride, calcium acetate, calcium sulfate, magnesium chloride, magnesium acetate, magnesium sulfate, nickel chloride, barium sulfate, zinc sulfide, zinc carbonate, aluminum silicate, calcium silicate, magnesium silicate, aluminum hydroxide, aluminum sulfate, aluminum phosphate, aluminum lactate, polyaluminum chloride, iron (III) sulfate, potassium aluminum sulfate, potassium iron alum, and ammonium iron alum.

[0049] Examples of the organic salt include ammonium acetate, ammonium formate, ammonium oxalate, and ammonium lactate.

[0050] As the cationic polymer, for example, a quaternary ammonium salt type cationic polymer compound is preferable, and specific examples thereof include dialkylallyl ammonium chloride polymer, dialkylaminoethyl (meth)acrylate quaternary ammonium salt polymer, modified polyvinyl alcohol dialkyl ammonium salt polymer, and dialkyl diallyl ammonium salt polymer. Other examples of the cationic polymer include cationic specially modified polyamine compounds, cationic polyamide polyamine compounds, cationic urea-formalin resin compounds, cationic polyacrylamide compounds, cationic alkyl ketene dimers, cationic dicyandiamide compounds, cationic dicyandiamide-formalin condensation compounds, cationic dicyandiamide-polyamine condensation compounds, cationic polyvinyl formamide compounds, cationic polyvinyl pyridine compounds, cationic polyalkylene polyamine compounds, and cationic epoxy polyamide compounds.

[0051] From the viewpoint of improving image density and suppressing bleeding in printed matter, the content of the coagulant is preferably from 0.1 to 10.0% by mass, and more preferably from 0.5 to 5.0% by mass, relative to the mass of the second treatment liquid.

[0052] <Ink application process> The ink application step is a step of applying ink to the area of ​​the fabric to which the first treatment liquid and the second treatment liquid have been applied, that is, the ink is applied to the area on the fabric that contains both the lubricant and the coagulant. The method of applying the ink is not particularly limited, and examples thereof include an inkjet method, a blade coating method, a gravure coating method, a bar coating method, a roll coating method, a dip coating method, a curtain coating method, a slide coating method, a die coating method, a spray coating method, etc. Among these, a step of discharging the ink onto the fabric by the inkjet method is preferable.

[0053] -ink- The ink contains an organic solvent, water, a coloring material, a resin, a surfactant, and other components. The details (type, amount, etc.) of the organic solvent, water, surfactant, and other components in the ink are the same as those described for the first treatment liquid above, and therefore a description thereof will be omitted. The physical properties of the ink are also the same as those described for the first treatment liquid above, and therefore a description thereof will be omitted. In addition, in accordance with the second treatment liquid containing a flocculant that is preferably cationic, at least one selected from the colorant and the resin is preferably anionic (these may be collectively referred to as an "anionic compound"). When at least one selected from the colorant and the resin is anionic, the ink flocculates or thickens when it comes into contact with a component (flocculant) contained in the second treatment liquid, which allows the colorant and the like to be retained on the surface of the fabric, improving image density.

[0054] --Coloring material-- The coloring material is not particularly limited, and a pigment or a dye can be used, but a pigment is preferable. Moreover, as described above, the coloring material is preferably anionic from the viewpoint of acting with the flocculant, and more preferably an anionic pigment.

[0055] Examples of pigments that can be used include black pigments, yellow pigments, magenta pigments, cyan pigments, white pigments, green pigments, orange pigments, glossy pigments such as gold and silver pigments, and metallic pigments.

[0056] As inorganic pigments, titanium oxide, iron oxide, calcium carbonate, barium sulfate, aluminum hydroxide, barium yellow, cadmium red, chrome yellow, as well as carbon black produced by known methods such as the contact method, furnace method, and thermal method can be used.

[0057] As organic pigments, azo pigments, polycyclic pigments (e.g., phthalocyanine pigments, perylene pigments, perinone pigments, anthraquinone pigments, quinacridone pigments, dioxazine pigments, indigo pigments, thioindigo pigments, isoindolinone pigments, quinophthalone pigments, etc.), dye chelates (e.g., basic dye chelates, acid dye chelates, etc.), nitro pigments, nitroso pigments, aniline black, etc. can be used. Among these pigments, those having good affinity with the solvent are preferably used. In addition, resin hollow particles and inorganic hollow particles can also be used.

[0058] Specific examples of pigments for black colors include carbon blacks (CI Pigment Black 7) such as furnace black, lamp black, acetylene black, and channel black; metals such as copper, iron (CI Pigment Black 11), and titanium oxide; and organic pigments such as aniline black (CI Pigment Black 1).

[0060] The dye is not particularly limited, and acid dyes, direct dyes, reactive dyes, and basic dyes can be used. One type of dye may be used alone, or two or more types may be used in combination. Dyes include, for example, CI Acid Yellow 17, 23, 42, 44, 79, 142, CI Acid Red 52, 80, 82, 249, 254, 289, CI Acid Blue 9, 45, 249, CI Acid Black 1, 2, 24, 94, CI Food Black 1, 2, CI Direct Yellow 1, 12, 24, 33, 50, 55, 58, 86, 132, 142, 144, 173, CI Direct Red 1, 4, 9, 80, 81, 225, 227, CI Direct Blue 1, 2, 15, 71, 86, 87, 98, 165, 199, 202, CI Directed Black 19, 38, 51, 71, 154, 168, 171, 195, CI Reactive Red 14, 32, 55, 79, 249, CI Reactive Black 3, 4, 35.

[0061] The content of the coloring material may be appropriately determined depending on the application of the ink, but is preferably from 0.1% to 15.0% by mass, and more preferably from 1.0% to 10.0% by mass, based on the mass of the ink.

[0062] Methods for dispersing a pigment to obtain an ink include a method of introducing a hydrophilic functional group into the pigment to make it a self-dispersing pigment, a method of dispersing the pigment by coating the surface of the pigment with a resin, and a method of dispersing the pigment using a dispersant. As a method for introducing a hydrophilic functional group into a pigment to make it a self-dispersing pigment, for example, a method in which a functional group such as a sulfone group or a carboxyl group is added to a pigment (e.g., carbon) to make it dispersible in water can be mentioned. As a method for dispersing a pigment by coating its surface with a resin, a method for encapsulating the pigment in a microcapsule to make it dispersible in water can be mentioned. This can be called a resin-coated pigment. In this case, it is not necessary for all the pigments used to be coated with resin, and uncoated pigments and partially coated pigments may be included. The method of dispersing using a dispersant includes a method of dispersing using a known low molecular weight dispersant or a polymeric dispersant, such as a surfactant. As the dispersant, for example, an anionic surfactant, a cationic surfactant, an amphoteric surfactant, a nonionic surfactant, etc. can be used depending on the pigment. RT-100 (nonionic surfactant) manufactured by Takemoto Oil Co., Ltd. and a formalin condensate of sodium naphthalenesulfonate can also be suitably used as a dispersant. The dispersant may be used alone or in combination of two or more kinds.

[0063] --resin-- The resin is not particularly limited and can be appropriately selected according to the purpose, and examples thereof include urethane resin, polyester resin, acrylic resin, vinyl acetate resin, styrene resin, butadiene resin, styrene-butadiene resin, vinyl chloride resin, acrylic styrene resin, and acrylic silicone resin. Among these, urethane resin is preferable from the viewpoint of image fastness and flexibility. In addition, the resin is preferably anionic from the viewpoint of acting with the flocculant, as described above.

[0064] The form of the resin in the ink is not particularly limited, but it is preferable that the resin is dispersed in the form of resin particles. The resin particles are dispersed in water as a dispersion medium in the form of a resin emulsion, and the ink can be obtained by mixing the resin particles with materials such as coloring materials and organic solvents. The resin particles may be appropriately synthesized or may be commercially available.

[0065] The volume average particle size of the resin particles is not particularly limited and can be appropriately selected depending on the purpose. From the viewpoint of obtaining good fixing property and high image hardness, however, it is preferably from 10 nm to 1,000 nm, more preferably from 10 nm to 200 nm, and even more preferably from 10 nm to 100 nm. The volume average particle size can be measured, for example, using a particle size analyzer (Nanotrac Wave-UT151, manufactured by Microtrac-Bell Co., Ltd.).

[0066] The resin content is not particularly limited and can be appropriately selected depending on the purpose. From the viewpoint of fixation property and storage stability of the ink, however, the resin content is preferably from 1.0% to 30.0% by mass, and more preferably from 5.0% to 20.0% by mass, relative to the mass of the ink.

[0067] <Fabric> The fabric is a material to which the first treatment liquid, the second treatment liquid, and the ink are applied, and a printed matter is formed by applying these. In the present disclosure, the term "fabric" refers to fibers in the form of woven fabric, knitted fabric, nonwoven fabric, or the like. The fibers are preferably organic fibers such as synthetic fibers, semi-synthetic fibers, regenerated fibers, and natural fibers. Examples of synthetic fibers include fibers such as polyester, polyamide, acrylic, polyolefin, polyvinyl alcohol, polyvinyl chloride, polyurethane, and polyimide. Examples of semi-synthetic fibers include fibers such as acetate, diacetate, and triacetate. Examples of regenerated fibers include fibers such as polynosic, rayon, lyocell, and cupra. Examples of natural fibers include fibers such as cotton, linen, silk, and wool.

[0068] In addition, the fibers may be fibers containing a biodegradable polyester composition. The biodegradable polyester composition may contain, for example, a biodegradable aliphatic-aromatic polyester or polylactic acid, and may contain an organic filler or an inorganic filler, if necessary. Examples of the biodegradable aliphatic-aromatic polyester include polybutylene adipate terephthalate (PBAT), polybutylene succinate terephthalate (PBST), and polybutylene sebacate terephthalate (PBSeT). Examples of the organic filler include natural starch, plasticized starch, modified starch, natural fiber, and wood flour. Examples of the inorganic filler include talc powder, montmorillonite, kaolin, chalk, calcium carbonate, graphite, gypsum, conductive carbon black, calcium chloride, iron oxide, dolomite, silica, wollastonite, titanium dioxide, silicate, mica, glass fiber, and mineral fiber.

[0069] Unlike films, papers, etc., printed matter using fabrics is often required to have properties such as dry rub fastness, washing fastness, flexibility, etc., due to the requirements of the application. Therefore, it is preferable to achieve these properties by using the first treatment liquid containing a lubricant as described above. In addition, since the ink is more easily permeated into the fabric than into films, papers, etc., the coloring material is less likely to remain on the surface of the fabric, making it difficult to obtain a printed matter with high image density. Therefore, it is preferable to improve the image density by using a second treatment liquid containing a flocculant.

[0070] <<Recording device>> The recording device has a first treatment liquid storage means that stores a first treatment liquid, a second treatment liquid storage means that stores a second treatment liquid, an ink storage means that stores ink, a first treatment liquid application means that applies the first treatment liquid to the fabric, a second treatment liquid application means that applies the second treatment liquid to the fabric, and an ink application means that applies ink to the area of ​​the fabric to which the first treatment liquid and the second treatment liquid have been applied, and may have other configurations as necessary, such as a heating means that heats the first treatment liquid, the second treatment liquid, or various liquids such as ink that have been applied to the fabric.

[0071] The recording apparatus will be described with reference to Figures 1 and 2. Figure 1 is a schematic diagram showing an example of a recording apparatus. Figure 2 is a schematic diagram showing an example of a storage means (first treatment liquid storage means, second treatment liquid storage means, or ink storage means).

[0072] The recording device 400 shown in Fig. 1 is an inkjet recording device having a serial type inkjet head. A mechanism unit 420 is provided inside an exterior 401 of the recording device 400. The first treatment liquid container means 410p1 for the first treatment liquid, the second treatment liquid container means 410p2, the black ink container means 410k for the black ink, and the container portion 411 in the cyan ink container means 410c for the cyan ink are formed of a packaging material such as an aluminum laminate film. The container portion 411 is contained in a container case 414 made of, for example, plastic. As a result, each container means 410 is used as a cartridge.

[0073] On the other hand, a cartridge holder 404 is provided at the back side of the opening when the cover 401c of the apparatus body is opened. Each storage means 410 is detachably attached to the cartridge holder 404. As a result, the outlet 413 of each storage means 410 communicates with an inkjet ejection head 434 (an example of a first treatment liquid applying means, a second treatment liquid applying means, and an ink applying means) via each supply tube 436, and the first treatment liquid, the second treatment liquid, and the ink can be ejected from the inkjet ejection head 434 onto the fabric.

[0074] The recording apparatus 400 may have a heating means for heating various liquids such as the first treatment liquid, the second treatment liquid, or the ink applied to the fabric. Examples of the heating means include known heating means such as a roll heater, a drum heater, a hot air generator, and a heat press device. EXAMPLES
