Mode for Carrying Out the Invention

[0007] Hereinafter, embodiments of the present invention (hereinafter referred to as "the present embodiment") will be described in detail. However, the present invention is not limited to this, and various modifications can be made without departing from the gist thereof.

[0008] 1. Treatment Liquid Composition for Dye Printing The treatment liquid composition for dye printing of the present embodiment (hereinafter also referred to as "treatment liquid composition") is a treatment liquid composition used by adhering it to a fabric, and includes resin particles, a thickener, and water. The viscosity of the treatment liquid composition at 20°C is 3.0 mPa·s or more, and the total concentration of potassium ions and sodium ions detected from the treatment liquid composition by ion chromatography is 100.0 ppm or less. The treatment liquid composition is preferably used to adhere to the fabric before dye printing the fabric.

[0009] According to the present embodiment, by previously adhering the treatment liquid composition to the fabric and performing dye printing on the fabric to which the treatment liquid composition is adhered, it is difficult for pretreatment marks to remain on the fabric after dye printing, and a printed matter having excellent color development and texture can be obtained.

[0010] Although the reason why such excellent effects are obtained according to this embodiment is not clear, the present inventors presume as follows. That is, usually, since fabrics are manufactured using components such as surfactants and pastes, those components remain almost uniformly throughout the fabric. Therefore, when the treatment liquid composition is attached to the fabric and dried, those components move and localize in the fabric as the drying progresses. The localized components may cause pretreatment marks on the fabric surface.

[0011] However, the treatment liquid composition of this embodiment contains resin particles, a thickener, and water, the viscosity of the treatment liquid composition at 20 °C is 3.0 mPa·s or more, and the total concentration of potassium ions and sodium ions detected from the treatment liquid composition by ion chromatography is 100.0 ppm or less. Since the viscosity of the treatment liquid composition at 20 °C is 3.0 mPa·s or more, it becomes possible to make the moving speed of components such as surfactants and pastes in the fabric slower. Therefore, in the fabric, localization derived from those components can be suppressed, and the appearance as pretreatment marks can be preferably suppressed.

[0012] In addition, a thickener is included in the treatment liquid composition for viscosity adjustment and the like, and the thickener may contain potassium ions and sodium ions. When a treatment liquid composition containing such a thickener is used as a pretreatment agent for a fabric, in the fabric, those ions react with carbon dioxide in the air to generate potassium carbonate salt and sodium carbonate salt. In that case, those carbonates may cause pretreatment marks on the fabric surface. However, in the treatment liquid composition of this embodiment, the total concentration of potassium ions and sodium ions detected from the treatment liquid composition by ion chromatography is 100.0 ppm or less. Therefore, in the fabric, it is difficult for those carbonates to be generated, and it is difficult for pretreatment marks derived from the carbonates to appear.

[0013] Furthermore, since the treatment liquid composition contains resin particles, the dye dissolved in the organic solvent also dyes the resin particles, and the resin particles can be appropriately present in the fabric. For such reasons, by attaching the treatment liquid composition of the present embodiment to the fabric and performing dye resist printing, it is possible to attach a large amount of ink in the vicinity of the fabric while having an appropriate texture.

[0014] From the above, it is presumed that by using the treatment liquid composition, it is difficult for pretreatment marks to remain on the fabric after dye resist printing, and it is possible to obtain a dyed product having excellent color development and texture. However, the reason is not limited to this.

[0015] Next, the physical properties of the treatment liquid composition and the ink composition, each component contained therein, and the application method of the treatment liquid composition will be described. First, the physical properties of the treatment liquid composition will be described.

[0016] 1.1. Physical Properties of Treatment Liquid Composition The physical properties of the treatment liquid composition can be arbitrarily adjusted depending on the type of fabric and the method of attaching it to the fabric, that is, the application method and the like.

[0017] 1.1.1. Viscosity The viscosity of the treatment liquid composition at 20°C is 3.0 mPa·s or more. When a treatment liquid composition having a viscosity within the above range is used for the fabric, it is possible to make the moving speed of components such as surfactants and pastes in the fabric slower. Therefore, localization derived from those components can be suppressed in the fabric, and the appearance as pretreatment marks on the fabric surface can be preferably suppressed. In addition, the coatability such as the ease of spreading of the treatment liquid when attached to the fabric can be improved.

[0018] The viscosity of the treatment liquid composition is measured using a viscoelasticity measuring device. Specifically, the temperature of the treatment liquid composition is adjusted to 20°C, and the shear viscosity (mPa·s) at a shear rate of 200 seconds -1 can be measured by reading it. A more specific measurement method can be referred to in the examples.

[0019] The viscosity of the treatment liquid composition at 20°C is preferably 3.0 mPa·s or more and 15.0 mPa·s or less, more preferably 3.0 mPa·s or more and 13.0 mPa·s or less. When the treatment liquid composition having a viscosity within the above range is used for the fabric, the appearance as a pretreatment mark on the fabric surface can be more preferably suppressed.

[0020] 1.1.2. Total Concentration The total concentration of potassium ions and sodium ions detected from the treatment liquid composition by ion chromatography (hereinafter, also simply referred to as "total concentration") in the treatment liquid composition is 100.0 ppm or less. When the treatment liquid composition having a total concentration within the above range is used for the fabric, it is difficult to generate potassium carbonate salt and sodium carbonate salt in the fabric, and the appearance as a pretreatment mark derived from carbonate on the fabric surface can be preferably suppressed.

[0021] The total concentration is measured using ion chromatography. Specifically, first, 20 g of the treatment liquid composition is centrifugally filtered at 8000 rpm for 5 minutes, then solid-liquid separated by a 0.2 μm size syringe filter, and the supernatant is collected. Thereafter, pure water is added to the supernatant to prepare a solution diluted 100 times. Using an ion chromatograph, the solution is measured, and the total concentration (ppm) of potassium ions and sodium ions detected from the treatment liquid composition is calculated using a calibration curve prepared in advance. For a more specific measurement method, reference can be made to the examples.

[0022] The total concentration is preferably 60.0 ppm or less, more preferably 30.0 ppm or less, still more preferably 10.0 ppm or less, and even more preferably 5.0 ppm or less. When the treatment liquid composition having a total concentration within the above range is used for the fabric, the appearance as a pretreatment mark on the fabric surface can be more preferably suppressed. The lower limit of the total concentration is not particularly limited. For example, considering the lower limit of quantification of ion chromatography, it is usually 1.0 ppm or more. Note that the lower limit of the total concentration may be 0.0 ppm.

[0023] 1.1.3. Surface Tension The surface tension of the treatment liquid composition at 25°C is preferably 30 mN / m or more and 50 mN / m or less. By setting the surface tension of the treatment liquid composition at 25°C within the above range, appropriate wettability and permeability to the fabric are exhibited. In addition, since the treatment liquid composition is easily absorbed uniformly by the fabric, it is possible to suppress the difference in the amount of adhesion generated when applying the treatment liquid composition, that is, the occurrence of coating unevenness.

[0024] Note that the surface tension of the treatment liquid composition can be measured, for example, using an automatic surface tension meter CBVP-Z (Kyowa Interface Science Co., Ltd.). Specifically, it can be measured by reading the surface tension when a platinum plate is wetted with the treatment liquid composition in an environment at 25°C.

[0025] 1.2. Resin particles The treatment liquid composition contains resin particles. By including resin particles in the treatment liquid composition, it is difficult for pretreatment marks to remain on the fabric after dye printing, and a printed matter having excellent color development and texture can be obtained.

[0026] Examples of the resin particles include polyester resins, urethane resins, addition polymerization resins, fluororesins, and natural resins. These resin particles are often handled in the form of an emulsion, that is, a resin dispersion, but may also be supplied in a powder state. The resin particles can be used alone or in combination of two or more.

[0027] Since it tends to be more difficult for pretreatment marks to remain on the fabric after dye printing, and a printed matter having more excellent color development and texture can be obtained, it is preferable that the resin particles contain one or more selected from the group consisting of polyester resins and urethane resins, and more preferably contain a polyester resin.

[0028] Since there is a tendency to obtain an impression with less remaining pretreatment marks, excellent texture, and even better color development properties, the glass transition temperature of the polyester resin is preferably -25°C or higher, more preferably 1°C or higher, still more preferably 15°C or higher, and even more preferably 25°C or higher. The upper limit is, for example, 180°C or lower, and may be 150°C or lower. In this specification, the glass transition temperature of the polyester resin can be measured, for example, by a differential scanning calorimeter (hereinafter also referred to as "DSC").

[0029] Examples of the polyester resin include resins having structural units derived from polyvalent carboxylic acids and structural units derived from polyhydric alcohols.

[0030] Examples of the polyvalent carboxylic acids include terephthalic acid, isophthalic acid, orthophthalic acid, phthalic acid, 4,4'-diphenyldicarboxylic acid, 2,5-naphthalenedicarboxylic acid, 1,5-naphthalenedicarboxylic acid, 2,6-naphthalenedicarboxylic acid, 2,7-naphthalenedicarboxylic acid, 1,4-cyclohexanedicarboxylic acid, 2-potassium sulfoterephthalic acid, 5-sodium sulfoisophthalic acid, adipic acid, azelaic acid, sebacic acid, dodecanedicarboxylic acid, glutaric acid, succinic acid, trimellitic acid, trimesic acid, pyromellitic acid, trimellitic anhydride, phthalic anhydride, succinic anhydride, and p-hydroxybenzoic acid, and their salts. Examples of the salts include potassium salts, sodium salts, calcium salts, and magnesium salts.

[0031] Examples of the polyhydric alcohol include ethylene glycol, 1,2-propylene glycol, 1,3-propylene glycol, 1,3-propanediol, 1,3-butylene glycol, 1,4-butanediol, 1,6-hexanediol, 2-methyl-1,5-pentanediol, neopentyl glycol, 1,4-cyclohexanedimethanol, p-xylylene glycol, bisphenol A-ethylene glycol adduct, diethylene glycol, triethylene glycol, polyethylene glycol, polypropylene glycol, polytetramethylene glycol, polytetramethylene oxide glycol, dimethylolpropionic acid, glycerin, trimethylolpropane, sodium dimethylol ethyl sulfonate, potassium dimethylol ethyl sulfonate, and potassium dimethylolpropionate.

[0032] The polyester resin preferably contains a hydroxyl group, a carboxyl group, a sulfonic acid group, and sodium salts thereof. These groups may be contained singly or in combination of two or more in the polyester resin.

[0033] The sulfonic acid group-containing polyester resin has, for example, a structural unit derived from a polyvalent carboxylic acid, a structural unit derived from a polyhydric alcohol, and a structural unit derived from a sulfonic acid group-containing aromatic monomer. Examples of the sulfonic acid group-containing aromatic monomer include 5-sulfoisophthalic acid, sulfoterephthalic acid, 4-sulfophthalic acid, 4-sulfonaphthalene-2,7-dicarboxylic acid, and 4-sulfo-1,8-naphthalenedicarboxylic anhydride, and salts thereof. As the salt, the above may be referred to, and a sodium salt is preferred.

[0034] When the polyester resin contains these groups, the polyester resin can react well with a crosslinking agent, preferably a compound containing an isocyanate group, and tends to have good binding properties with a fabric, preferably a fabric containing a fiber having a hydroxyl group. Therefore, it is difficult for pretreatment marks to remain, and there is a tendency to obtain an imprinted product having excellent texture and more excellent color developability.

[0035] The polyester resin can be obtained, for example, by appropriately selecting one or more from the above-mentioned polyvalent carboxylic acids, polyhydric alcohols, and, if necessary, sulfonic acid group-containing aromatic monomers, and synthesizing them by a conventional polycondensation reaction.

[0036] As such a polyester resin, commercially available products can also be used. Examples of commercially available products include Eritel (registered trademark) KA-5071S, KT-8803, KT-9204, KT-8701, KT-8904, and KT-0507 (above are product names, manufactured by Unitika Ltd., polyester resin emulsion); Hi-Tech (registered trademark) SN-2002 (product name, manufactured by Toho Chemical Industry Co., Ltd., polyester resin emulsion); Plascoat (registered trademark) Z-221, Z-446, Z-561, Z-565, RZ-570, Z-592, Z-687, Z-690, Z-730, Z-760, RZ-105, RZ-570, and RZ-760 (above are product names, manufactured by Gohsei Chemical Industry Co., Ltd.); Bayronal (registered trademark) MD-1200, MD-1500, and MD-2000 (above are product names, manufactured by Toyobo Co., Ltd.).

Examples of urethane resins include, for example, polyether-type urethane resins containing an ether bond in the main chain, polyester-type urethane resins containing an ester bond in the main chain, and polycarbonate-type urethane resins containing a carbonate bond in the main chain, in addition to the urethane bond. Also, commercially available products can be used as the urethane resin.

[0040] In addition, although commercially available products were listed above, the resin particles may also be obtained by synthesis according to conventional methods.

[0041] Since there is a tendency to obtain an impressed article with less remaining pretreatment marks and having better color development property and texture, the content of the resin particles is preferably 1.0% by mass or more and 25.0% by mass or less in terms of solid content based on the total amount of the treatment liquid composition. Since there is a tendency to obtain an impressed article with less remaining pretreatment marks, having better texture and further better color development property, the content of the resin particles is more preferably 4.0% by mass or more and 25.0% by mass or less in terms of solid content based on the total amount of the treatment liquid composition. Since there is a tendency to obtain an impressed article with less remaining pretreatment marks and having further better color development property and texture, the content of the resin particles is still more preferably 3.0% by mass or more and 15.0% by mass or less in terms of solid content based on the total amount of the treatment liquid composition.

[0042] 1.3. Thickener The treatment liquid composition contains a thickener. By including a thickener in the treatment liquid composition, it is difficult for pretreatment marks to remain on the fabric after dye printing, and a printed article having excellent color development property and texture can be obtained. The thickener may be used alone or in combination of two or more.

[0043] In this specification, the thickener is a substance that can adjust the viscosity of the treatment liquid composition, and is preferably a substance that increases the viscosity.

[0044] Examples of thickeners include plant polymers such as gum arabic, tragacanth, galactan, carob gum, guar gum, karaya gum, carrageenan, pectin, agar, quince seed, algal colloid, trant gum, glucomannan, dextrin, cyclodextrin, tamarind gum, nori, pectic acid, shirataki gum, and locust bean gum; microbial polymers such as xanthan gum, dextran, succinoglucan, and pullulan; animal polymers such as collagen, casein, albumin, glue, and gelatin; starch polymers such as starch, roasted starch, alpha starch, oxidized starch, carboxyl starch, carboxymethyl starch, carboxyethyl starch, hydroxyethyl starch, dialdehyde starch, and methyl hydroxypropyl starch; cellulose polymers such as cellulose, methyl cellulose, ethyl cellulose, methyl hydroxypropyl cellulose, carboxymethyl cellulose, hydroxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, nitrocellulose, sodium cellulose sulfate, sodium carboxymethyl cellulose, crystalline cellulose, cationized cellulose, and cellulose powder; alginic acid polymers such as sodium alginate, potassium alginate, ammonium alginate, and propylene glycol alginate; vinyl polymers such as polyvinyl pyrrolidone, polyvinyl alcohol, polyvinyl formal, polyvinyl methyl ether, and carboxyvinyl polymer; acrylic polymers such as polyoxyethylene polymers, polyoxyethylene polyoxypropylene copolymer polymers, modified polyacrylic acid, modified polyacrylic acid emulsion, sodium polyacrylate, polyethyl acrylate, polyacrylamide, and acryloyldimethyltaurine salt copolymer; methacrylic polymers such as modified polymethacrylic acid, modified polymethacrylic acid emulsion, sodium polymethacrylate, polyethyl methacrylate, polymethacrylamide, and methacryloyldimethyltaurine salt copolymer; synthetic water-soluble polymers such as urethane-modified polyethers, polyethyleneimine, and cationic polymers;Examples thereof include inorganic water-soluble polymers such as bentonite, magnesium aluminum silicate, montmorillonite, beidellite, nontronite, saponite, hectorite, and anhydrous silicic acid;

[0045] Since it tends to be more difficult for pretreatment marks to remain and an impressed article having more excellent color developability and texture can be obtained, the thickener preferably contains at least one selected from the group consisting of microbial polymers, cellulose polymers, alginic acid polymers, vinyl polymers, and synthetic water-soluble polymers, and more preferably contains at least one selected from the group consisting of xanthan gum, carboxymethyl cellulose, sodium alginate, polyvinylpyrrolidone, and urethane-modified polyether.

[0046] As such thickeners, commercially available products can also be used. Examples of commercially available products include SOKALAN® K-17P, K-30P, K-60P, K-80P, K-85P, K-90P, K-115P (trade name, BAFS SE, polyvinylpyrrolidone); Pittcol® K30, K-50, K-80, K-85, K-90, K-17L, K-30L, K-30AL, K-60L, K-90L, K-120L (trade name, Daiichi Kogyo Seiyaku Co., Ltd., polyvinylpyrrolidone); Crejas® K-30, K-90 (trade name, Daiichi Kogyo Seiyaku Co., Ltd., polyvinylpyrrolidone); SN Thickeners 621TF (trade name, Sannapco Co., Ltd., urethane-modified polyether); SN Thickeners 929 (trade name, Sannapco Co., Ltd., sodium polycarboxylate); SN Thickeners 630, 920 (above, trade name, Sannapco Co., Ltd., modified polyacrylic acid emulsion); SN Thickeners 617 (trade name, Sannapco Co., Ltd., modified polyacrylic acid); Bistool® 3015 (trade name, Sannapco Co., Ltd., modified polyacrylic acid emulsion); KELZAN® T, S, AR, RD, ST, M, HP, ASX (above, trade name, Sankyo Co., Ltd., xanthan gum); Echo Gum® and Monart Gum® GS (above, trade name, Sumitomo Pharma Co., Ltd., xanthan gum); CEKOL® 150, 700, 30000 (carboxymethyl cellulose) (above, trade name, Sankyo Co., Ltd.).

[0047] Since it tends to be more difficult for pretreatment marks to remain and a stamped article having more excellent color development property and texture can be obtained, the content of the thickener is preferably 0.01% by mass or more and 10.0% by mass or less, more preferably 0.02% by mass or more and 7.0% by mass or less, and still more preferably 0.03% by mass or more and 5.0% by mass or less in terms of solid content based on the total amount of the treatment liquid composition.

[0048] 1.4. Water The treatment liquid composition contains water. After the treatment liquid composition is attached to the fabric, water evaporates by drying. Examples of water include pure water such as ion-exchanged water, ultrafiltration water, reverse osmosis permeated water, and distilled water, and those with extremely low ionic impurities such as ultrapure water. In addition, water sterilized by ultraviolet irradiation or addition of hydrogen peroxide is preferable when storing the treatment liquid composition for a long time because it can suppress the generation of mold and bacteria.

[0049] The water content is preferably 30.0% by mass or more and 99.0% by mass or less, more preferably 35.0% by mass or more and 98.0% by mass or less, based on the total amount of the treatment liquid composition. By setting the water content within the above range, an increase in the viscosity of the treatment liquid composition can be suppressed, and the workability when attaching the treatment liquid composition to the fabric and the drying property after attachment can be improved. Since higher affinity and higher safety can be obtained for fabrics, preferably fabrics containing fibers having hydroxyl groups, the treatment liquid composition is preferably an aqueous treatment liquid composition. In this embodiment, "aqueous" means that the water content relative to the total amount of the composition is 30.0% by mass or more.

[0050] 1.5. Crosslinking agent The treatment liquid composition preferably further contains a crosslinking agent. In the treatment liquid composition, by including a crosslinking agent, crosslinkability can be imparted to the treatment liquid composition, enabling the binding of resin particles, dyes, and fabrics. Therefore, it is difficult for pretreatment marks to remain, and there is a tendency to obtain printed matter with excellent texture and more excellent color development properties. The crosslinking agent may be used alone or in combination of two or more.

[0051] The crosslinking agent can be appropriately selected from known crosslinking agents and may be one that starts a crosslinking reaction at room temperature or one that starts a crosslinking reaction by heat. Examples of such crosslinking agents include crosslinking agents having self-crosslinkability, compounds having a plurality of functional groups in the molecule that react with an unsaturated carboxylic acid component, and metals having polyvalent coordination sites.

[0052] Since there is a tendency to obtain an impressed article that is less likely to have pretreatment marks remaining, has better texture, and further has better coloring properties, as the crosslinking agent, it is preferable to include at least one selected from the group consisting of compounds containing isocyanate groups and compounds containing oxazoline groups, and it is more preferable to include a compound containing an isocyanate group.

[0053] Examples of the compound containing an isocyanate group include water-dispersible (block) polyisocyanate and the like. Note that (block) polyisocyanate means polyisocyanate and / or blocked polyisocyanate. These compounds containing isocyanate groups may be used alone or in combination of two or more.

[0054] Examples of the water-dispersible polyisocyanate include those obtained by dispersing a polyisocyanate imparted with hydrophilicity by a polyethylene oxide chain in water with an anionic dispersant or a nonionic dispersant.

[0055] Examples of the polyisocyanate include diisocyanates such as hexamethylene diisocyanate and isophorone diisocyanate; derivatives (modified products) of polyisocyanates such as trimethylolpropane adducts, biuret bodies, and isocyanurate bodies of these diisocyanates. Further, the polyisocyanate may have an isocyanurate skeleton in its structure. These polyisocyanates may be used alone or in combination of two or more.

[0056] The water-dispersible blocked polyisocyanate is obtained by blocking the isocyanate groups of the water-dispersible polyisocyanate with a blocking agent. Examples of the blocking agent include diethyl malonate, ethyl acetoacetate, ε-caprolactam, butanone oxime, cyclohexanone oxime, 1,2,4-triazole, dimethyl-1,2,4-triazole, 3,5-dimethylpyrazole, and imidazole. These blocking agents may be used alone or in combination of two or more.

[0057] The crosslinking agent is preferably a compound containing an isocyanate group having an isocyanurate skeleton in its structure, and more preferably a water-dispersible polyisocyanate having an isocyanurate skeleton in its structure. Since the compound containing an isocyanate group having an isocyanurate skeleton has at least three crosslinking points, it tends to make the binding property between the resin particles and the fabric more suitable. Therefore, it is difficult for pretreatment marks to remain, and there is a tendency to obtain an impressed article having excellent texture and further excellent color developability.

[0058] Commercially available products can also be used as such a compound containing an isocyanate group. Examples of the commercially available products include Fixer #100ECO, #104EA, #220, 70ECO, #70, #410, and #400 (above, trade names, Murayama Chemical Laboratory Co., Ltd.); Elastron (registered trademark) BN-11, BN-27, BN-69, and BN-77 (above, trade names, Dai-ichi Kogyo Seiyaku Co., Ltd.).

[0059] Examples of the oxazoline group-containing compound include compounds having two or more oxazoline groups in the molecule. Examples of such oxazoline group-containing compounds include 2,2'-bis(2-oxazoline), 2,2'-methylene-bis(2-oxazoline), 2,2'-ethylene-bis(2-oxazoline), 2,2'-trimethylene-bis(2-oxazoline), 2,2'-tetramethylene-bis(2-oxazoline), 2,2'-hexamethylene-bis(2-oxazoline), 2,2'-octamethylene-bis(2-oxazoline), 2,2'-ethylene-bis(4,4'-dimethyl-2-oxazoline), 2,2'-p-phenylene-bis(2-oxazoline), 2,2'-m-phenylene-bis(2-oxazoline), 2,2'-m-phenylene-bis(4,4'-dimethyl-2-oxazoline), bis(2-oxazolinylcyclohexane) sulfide, bis(2-oxazolinylnorbornane) sulfide, and oxazoline ring-containing polymers. These oxazoline group-containing compounds may be used alone or in combination of two or more.

[0060] Since it is difficult for pretreatment traces to remain, and there is a tendency to obtain an impressed article having excellent texture and more excellent color development property, it is preferable that the oxazoline group-containing compound includes a water-soluble oxazoline group-containing compound.

[0061] As such an oxazoline group-containing compound, commercially available products can also be used. Examples of the commercially available products include Epocros (registered trademark) K-2010, K-2020, K-2030, K-2035E, WS-300, WS-500, and WS-700 (above are trade names, Nippon Shokubai Co., Ltd.).

[0062] Since there is a tendency to obtain an impressed article with less remaining pre-treatment marks and having more excellent color development property and texture, the content of the crosslinking agent is preferably 0.5% by mass or more and 5.0% by mass or less in terms of solid content based on the total amount of the treatment liquid composition. Since there is a tendency to obtain an impressed article with less remaining pre-treatment marks, having more excellent texture and further excellent color development property, the content of the crosslinking agent is more preferably 1.5% by mass or more and 4.5% by mass or less in terms of solid content based on the total amount of the treatment liquid composition. Since there is a tendency to obtain an impressed article with less remaining pre-treatment marks and having further excellent color development property and texture, the content of the crosslinking agent is still more preferably 1.5% by mass or more and 2.5% by mass or less in terms of solid content based on the total amount of the treatment liquid composition.

[0063] 1.6. Organic solvent The treatment liquid composition preferably further contains an organic solvent. By the treatment liquid composition further containing an organic solvent, it is difficult for pre-treatment marks to remain on the fabric after dye printing, and an impressed article having excellent texture and more excellent color development property can be obtained. The organic solvent can be used alone or in combination of two or more.

[0064] Examples of the organic solvent include glycerin; glycols such as ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, dipropylene glycol, 1,3 - propanediol, 1,2 - butanediol, 1,2 - pentanediol, 1,2 - hexanediol, 1,4 - butanediol, 1,5 - pentanediol, and 1,6 - hexanediol; glycol monoethers such as ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, propylene glycol monomethyl ether, propylene glycol monoethyl ether, dipropylene glycol monomethyl ether, dipropylene glycol monoethyl ether, and methyl triglycol; nitrogen - containing solvents such as 2 - pyrrolidone, N - methyl - 2 - pyrrolidone, and N - ethyl - 2 - pyrrolidone; and alcohols such as methanol, ethanol, n - propyl alcohol, iso - propyl alcohol, n - butanol, 2 - butanol, tert - butanol, iso - butanol, n - pentanol, 2 - pentanol, 3 - pentanol, and tert - pentanol.

[0065] Since it is difficult for pretreatment traces to remain further and a printed and dyed product with more excellent color - developing property and texture can be obtained, the organic solvent preferably contains glycols, and more preferably contains 1,2 - hexanediol.

[0066] The content of the organic solvent is preferably 5.0% by mass or more, more preferably 5.0% by mass or more and 30.0% by mass or less, and still more preferably 10.0% by mass or more and 20.0% by mass or less with respect to the total amount of the treatment liquid composition. By setting the content of the organic solvent within the above range, there is a tendency to obtain a printed and dyed product in which pretreatment traces are more difficult to remain and which has more excellent color - developing property and texture.

[0067] 1.7. Other Components The treatment liquid composition may contain various additives such as surfactants, solubilizers, humectants, pH adjusters, antioxidants, preservatives, fungicides, corrosion inhibitors, and chelating agents. The additives may be used alone or in combination of two or more.

[0068] The content of the additives is, for example, 0.01% by mass or more and 5.0% by mass or less with respect to the total amount of the treatment liquid composition.

[0069] 1.8. Method for preparing the treatment liquid composition The treatment liquid composition can be prepared by mixing each component in an arbitrary order and, if necessary, performing filtration or the like to remove impurities, foreign matters, etc. As a method for mixing each component, a method of sequentially adding each component to a container equipped with a stirring device such as a mechanical stirrer and a magnetic stirrer and stirring and mixing them is used. Examples of the filtration method include centrifugal filtration and filter filtration.

[0070] 2. Inkjet ink composition The inkjet ink composition (hereinafter also referred to as "ink composition") is used to produce a printed matter by printing on a fabric to which the treatment liquid composition of the present embodiment is adhered. Next, the ink composition will be described. The ink composition according to the present embodiment contains a disperse dye and water.

[0071] 2.1. Disperse dye Since excellent color development properties tend to be obtained for the fabric to which the treatment liquid composition is adhered, the ink composition contains a disperse dye as a dye. Disperse dyes usually form particles and are color materials dispersed in a dispersion medium by a dispersant. Also, disperse dyes are usually nonionic dyes having a hydrophilic group and an appropriate polar group. The disperse dyes may be used alone or in combination of two or more.

[0072] Examples of disperse dyes include C.I. Disperse Yellow, C.I. Disperse Red, C.I. Disperse Blue, C.I. Disperse Orange, C.I. Disperse Violet, C.I. Disperse Green, C.I. Disperse Brown, and C.I. Disperse Black.

[0073] Among them, sublimable dyes are preferred as the disperse agent. In this specification, "sublimable dye" refers to a dye having the property of sublimating upon heating. Specific examples of such sublimable dyes include C.I. Disperse Yellow 3, 7, 8, 23, 39, 51, 54, 60, 71, and 86; C.I. Disperse Orange 1, 1:1, 5, 20, 25, 25:1, 33, 56, and 76; C.I.

Solvent Blue 36, 63, 105, and 111, etc.

[0074] In this embodiment, since better dyeability can be obtained for the fabric to which the treatment liquid composition adheres, and a stamped article having sufficient color development tendency can be obtained, cyan dyes, red dyes, and yellow dyes are preferred. Further, since better dyeability can be obtained and a stamped article having sufficient color development tendency can be obtained, as the cyan dye, C.I. Disperse Blue 359 is more preferred. As the red dye, C.I. Disperse Red 60 is more preferred. As the yellow dye, C.I. Disperse Yellow 54 is more preferred.

[0077] From the viewpoint of more effectively and surely achieving the operational effects of the present embodiment, the content of water is preferably 30.0% by mass or more and 80.0% by mass or less with respect to the total amount of the ink composition.

[0078] 2.3. Dispersant The ink composition may contain a dispersant. When the ink composition contains a dispersant, the dispersibility of the disperse dye is excellent and the clogging resistance of the ink composition is excellent. Examples of the dispersant include sodium naphthalenesulfonate-formalin condensate and resins. The sodium naphthalenesulfonate-formalin condensate is a compound obtained by condensing a sulfonated product having a naphthalene ring in the molecule with formalin, or a salt thereof. The dispersant may be used alone or in combination of two or more.

[0079] Since it has better dispersibility, it is preferable that the dispersant contains a resin. Examples of the resin include urethane resins, styrene-acrylic resins, acrylic resins, fluorene resins, polyolefin resins, rosin-modified resins, terpene resins, polyester resins, polyamide resins, epoxy resins, vinyl chloride resins, vinyl chloride-vinyl acetate copolymers, and ethylene-vinyl acetate resins. Among them, from the viewpoint of excellent clogging resistance, urethane resins and styrene-acrylic resins are preferable as the resin, and styrene-acrylic resins are more preferable.

[0080] The urethane resin is not particularly limited as long as it has a urethane bond in the molecule. Examples of urethane resins include polyether-type urethane resins containing an ether bond in the main chain, polyester-type urethane resins containing an ester bond in the main chain, and polycarbonate-type urethane resins containing a carbonate bond in the main chain, in addition to the urethane bond. The urethane resin may be used alone or in combination of two or more.

Examples of commercially available products include Joncryl (registered trademark) 67 (trade name) manufactured by BASF Japan Ltd., and Solsperse (registered trademark) 43000 (trade name) manufactured by Lubrizol Corporation.

[0084] From the viewpoint of more effectively and surely achieving the effects of this embodiment, the content of the dispersant is preferably 3.0% by mass or more and 8.0% by mass or less based on the total amount of the ink composition.

[0085] 2.4. Surfactant The ink composition may contain a surfactant. Examples of the surfactant include acetylene glycol-based surfactants, fluorine-based surfactants, and silicone-based surfactants. The surfactant may be used alone or in combination of two or more.

[0086] Examples of the acetylene glycol-based surfactant include 2,4,7,9-tetramethyl-5-decyne-4,7-diol and its alkylene oxide adducts, and 2,4-dimethyl-5-decyne-4-ol and its alkylene oxide adducts.

[0089] From the viewpoint of more effectively and surely achieving the effects of the present embodiment, the content of the surfactant is preferably 0.5% by mass or more and 5.0% by mass or less based on the total amount of the ink composition.

[0090] 2.5. Water-soluble organic solvent The ink composition may contain a water-soluble organic solvent. Examples of the water-soluble organic solvent include glycerin; glycols such as ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, dipropylene glycol, 1,3-propanediol, 1,2-butanediol, 1,2-pentanediol, 1,2-hexanediol, 1,4-butanediol, 1,5-pentanediol, and 1,6-hexanediol; glycol monoethers such as ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, propylene glycol monomethyl ether, propylene glycol monoethyl ether, dipropylene glycol monomethyl ether, dipropylene glycol monoethyl ether, and methyl triglycol; nitrogen-containing solvents such as 2-pyrrolidone, N-methyl-2-pyrrolidone, and N-ethyl-2-pyrrolidone; and alcohols such as methanol, ethanol, n-propyl alcohol, iso-propyl alcohol, n-butanol, 2-butanol, tert-butanol, iso-butanol, n-pentanol, 2-pentanol, 3-pentanol, and tert-pentanol. The water-soluble organic solvent may be used alone or in combination of two or more.

[0091] Glycerin, glycols, and glycol monoethers can mainly function as penetration solvents and / or humectants. Glycol monoethers tend to have strong properties as penetration solvents, and glycerin and glycols tend to have strong properties as humectants.

[0092] From the perspective of more effectively and reliably achieving the effects of this embodiment, the content of the water-soluble organic solvent is preferably 5.0% by mass or more and 30.0% by mass or less based on the total amount of the ink composition.

[0093] 2.6. Other Components The ink composition may contain various additives such as a dissolution aid, a viscosity modifier, a pH adjuster, an antioxidant, a preservative, a fungicide, a corrosion inhibitor, and a chelating agent for capturing metal ions that affect dispersion. The additives may be used alone or in combination of two or more.

Commercially available products can also be used as the preservative. Examples of commercially available products include CRL, BND, GXL, XL-2, and TN (above, trade names) of the Proxel (registered trademark) series manufactured by Lonza Japan Co., Ltd. The preservatives may be used alone or in combination of two or more.

[0095] The content of each additive is 0.01% by mass or more and 5.0% by mass or less based on the total amount of the ink composition.

[0096] 2.7. Method for Producing Ink Composition The ink composition can be prepared by mixing a disperse dye, water, and, if necessary, other components in an arbitrary order, and, if necessary, performing filtration or the like to remove impurities, foreign substances, and the like. As a method for mixing each component, a method of sequentially adding each component to a container equipped with a stirring device such as a mechanical stirrer and a magnetic stirrer, and stirring and mixing is used. Examples of the filtration method include centrifugal filtration and filter filtration.

[0097] Also, in the ink composition, in order to disperse the disperse dye better, a dye dispersant may be prepared in advance, and instead of the disperse dye, the ink composition may be prepared using the dye dispersant. The dye dispersant can be obtained, for example, by mixing a disperse dye, water, and a dispersant in any order and dispersing them with a paint shaker or the like.

[0098] 3. Composition set The composition set includes the above-described treatment liquid composition and the above-described ink composition.

[0099] In this embodiment, the treatment liquid composition is attached to the fabric in advance to obtain a fabric with the treatment liquid composition attached. Then, the fabric with the treatment liquid composition attached is subjected to resist dyeing with the ink composition. By using the treatment liquid composition, it is difficult for pretreatment marks to remain on the fabric after dye resist printing, and a dyed product having excellent color development and texture can be obtained.

[0100] 4. Fabric Examples of the fabric according to this embodiment include natural fibers such as cotton, hemp, wool, leather, and silk; synthetic fibers such as nylon, polypropylene, polyester, acetate, triacetate, polyamide, acrylic, and polyurethane; biodegradable fibers such as polylactic acid; metals such as iron, zinc, stainless steel, aluminum, gold, silver, and copper; plastics such as polyethylene, polypropylene, and polyethylene terephthalate; paper, etc. Also, the fabric may be a blended fiber thereof.

[0101] Since it tends to be difficult for pretreatment marks to remain on the fabric after dye resist printing, and a stamped product having better color development and texture can be obtained, the fabric is preferably cotton, hemp, nylon, wool, acrylic, silk, leather, polyester, metal, plastic, or paper, more preferably contains fibers having a hydroxyl group, and even more preferably is cotton. The fibers having a hydroxyl group may be blended fibers thereof.

[0102] Examples of the form of the fabric include woven fabrics, knitted fabrics, non-woven fabrics, cloth, as well as clothing and other apparel. Clothing and other apparel include T-shirts after sewing, handkerchiefs, scarves, towels, tote bags, cloth bags, curtains, sheets, bed covers, and furniture such as wallpaper; the cloth before and after cutting as parts before sewing. Their forms include long ones rolled in a roll shape, those cut into a predetermined size, and those in a product shape. Note that it is sufficient that the treatment liquid composition adheres to the fabric, and a fabric having the treatment liquid composition previously applied thereto may be used.

[0103] Examples of the basis weight of the fabric are, for example, 1.0 oz or more and 10.0 oz or less. If the basis weight of the fabric is within such a range, good recording can be performed.

[0104] The fabric is preferably a white fabric. Even if it is a white fabric, by using the treatment liquid composition, it is difficult for pretreatment marks to remain on the fabric after dye printing, and a printed matter having excellent color development and texture can be obtained.

[0105] Furthermore, as the fabric, it is more preferable that they are white cotton-made furniture such as white cotton T-shirts. Usually, components for maintaining and improving whiteness remain in white cotton-made furniture, but even if such components remain, by using the treatment liquid composition, it is difficult for pretreatment marks to remain on the fabric after dye printing, and a printed matter having excellent color development and texture can be obtained.

[0106] As the fabric, a fabric previously colored with a dye may be used. Since the treatment liquid composition is less likely to cause pretreatment marks, it can be used even for a fabric previously colored. That is, even if the fabric is colored, it is possible to perform printing with suppression of the generation of pretreatment marks, so that the quality and commercial value of the printed matter as a product can be enhanced compared to the conventional ones.

[0107] Examples of dyes for pre-coloring fabrics include water-soluble dyes such as acid dyes and basic dyes; disperse dyes used in combination with a dispersant; reactive dyes; solvent dyes and the like. When using cotton fabric as the fabric, it is preferable to use disperse dyes and reactive dyes suitable for dyeing cotton, and disperse dyes are more preferable.

[0108] 5. Dyeing method 5.1. Process liquid composition adhesion step The dyeing method of this embodiment includes a process liquid composition adhesion step of adhering a process liquid composition to a fabric. By going through this step, a fabric with the process liquid composition adhered thereto can be obtained. Further, an ink composition is adhered to this fabric. By using the process liquid composition, it is difficult for pretreatment marks to remain on the fabric after dye printing, and a dyed product having excellent color development and texture can be obtained. The dyeing method can be applied to various fabrics and can perform good printing.

[0109] The dyeing method preferably includes an ink composition adhesion step of adhering an ink composition to the fabric with the process liquid composition adhered thereto after the above-described process liquid composition adhesion step. The ink composition to be adhered to the fabric is not particularly limited as long as it contains a disperse dye. For example, the inkjet ink composition according to this embodiment can be used. Further, for the ink composition adhesion step, reference can be made to the dyeing method using the inkjet method described later.

[0110] The adhesion amount of the process liquid composition on the fabric is, for example, made to adhere so as to be 0.02 g / cm 2 or more and 0.5 g / cm 2 or less, and it is preferably made to adhere so as to be 0.02 g / cm 2 or more and 0.3 g / cm 2 or less. By setting the adhesion amount of the process liquid composition within the above range, the process liquid composition can be adhered to the fabric more uniformly, the aggregation unevenness of the image in the printed matter can be further suppressed, and the color development can be enhanced.

[0111] As a method of attaching the treatment liquid composition to the fabric, for example, there are a dipping coating method of immersing the fabric in the treatment liquid composition, a roller coating method of applying the treatment liquid composition with a mangle roller, a roll coater, etc., a spray coating method of spraying the treatment liquid composition with a spray device, etc., and an inkjet coating method of injecting the treatment liquid composition by an inkjet method. These coating methods may use one method alone to attach the treatment liquid composition to the fabric, or may combine two or more methods to attach the treatment liquid composition to the fabric. In the present embodiment, since the degree of freedom in designing the adhesion amount of the treatment liquid composition is increased, it is difficult to cause defects during adhesion, and the treatment liquid composition can be uniformly adhered to the fabric, it is preferable to use a roller such as a mangle roller and a roll coater to attach the treatment liquid composition to the fabric.

[0112] 5.2. Drying step In the printing and dyeing method, it is preferable to include a drying step of drying the treatment liquid composition adhered to the fabric after the treatment liquid composition adhesion step of adhering the treatment liquid composition to the fabric. The drying of the treatment liquid composition may be performed by natural drying, but from the viewpoint of improving the adhesion amount of the treatment liquid composition to the fabric and also improving the drying speed, drying with heating is preferable.

[0113] Since it is less likely that pretreatment marks remain on the fabric after dye printing and dyeing, and there is a tendency to obtain a printed product having better color development and texture, the drying temperature is preferably 300 ° C or lower, more preferably 200 ° C or lower. Further, by setting the upper limit of the drying temperature within this range, even if the fabric is pre-colored with a dye, sublimation of the dye due to heat drying can be suppressed, and fading of the fabric base color can be suppressed. The lower limit of the heating temperature is such that the medium such as moisture contained in the treatment liquid composition may volatilize, preferably 50 ° C or higher, more preferably 100 ° C or higher, and still more preferably 110 ° C or higher.

[0114] Examples of the heating method include a heat press method, an atmospheric pressure steam method, a high pressure steam method, and a thermofix method. Examples of the heat source for heating include warm air, infrared rays (lamps), and microwaves.

[0115] The heating time is preferably 1 second or more and 5 minutes or less. When the heating time is within the above range, volatile components such as organic solvents and water can be more preferably volatilized from the fabric, and damage to the fabric also tends to be reduced.

[0116] In the printing and dyeing method, after the treatment liquid composition is adhered to the fabric, a washing step may be included as necessary. By including this step in the printing and dyeing method, components contained in the treatment liquid composition that are not adhered to the fabric can be removed.

[0117] 6. Inkjet printing and dyeing method The inkjet printing and dyeing method is a method of adhering an ink composition to a fabric to which a treatment liquid composition has been adhered, using the inkjet method. By adopting the inkjet method, a dyed portion with a fine pattern can be easily and surely formed. In addition, it can be applied to various fabrics and good printing can be performed. By the inkjet printing and dyeing method, good printing with a small difference in color between the front and back can be performed even on thick fabrics. Examples of the inkjet printing and dyeing method include an indirect printing and dyeing recording method and a direct printing and dyeing recording method.

[0118] 6.1. Inkjet recording apparatus As an inkjet recording apparatus used in the printing method, it is not particularly limited as long as it has at least an ink container for storing an ink composition and a recording head connected thereto, and can form an image on a cloth to which a treatment liquid composition adheres or a transfer paper which is an intermediate transfer medium by discharging the ink composition from the recording head. Further, as the inkjet recording apparatus, either a serial type or a line type can be used. A recording head is mounted on these types of inkjet recording apparatuses, and droplets of the ink composition are intermittently discharged from the nozzle holes of the recording head at a predetermined volume and at a predetermined timing while changing the relative positional relationship between the cloth or transfer paper and the recording head. Thereby, an ink composition can be adhered to the cloth or transfer paper to form a predetermined transfer image.

[0119] Generally, in a serial type inkjet recording apparatus, the conveyance direction of the recording medium intersects with the reciprocating operation direction of the recording head, and the relative positional relationship between the recording medium and the recording head is changed by a combination of the reciprocating operation of the recording head and the conveyance operation of the recording medium. Also in this case, generally, a plurality of nozzle holes are arranged in the recording head, and a row of nozzle holes, that is, a nozzle row, is formed along the conveyance direction of the recording medium. Further, depending on the type and number of the ink compositions, a plurality of nozzle rows may be formed in the recording head.

[0120] Also generally, in a line type inkjet recording apparatus, the recording head does not perform a reciprocating operation, and the relative positional relationship between the recording medium and the recording head is changed by the conveyance of the recording medium to change the relative positional relationship between the recording medium and the recording head. Also in this case, generally, a plurality of nozzle holes are arranged in the recording head, and a nozzle row is formed along a direction intersecting the conveyance direction of the recording medium.

[0121] 6.2. Indirect printing recording method The inkjet printing method of this embodiment includes a treatment liquid composition adhesion step of adhering a treatment liquid composition to a fabric, a discharge step of discharging an ink composition from a recording head and adhering it to an intermediate transfer medium, and a transfer step of transferring the ink composition adhered to the intermediate transfer medium to the fabric to which the treatment liquid composition obtained in the treatment liquid composition adhesion step is adhered. Specifically, in this printing method, an ink composition containing a disperse dye such as a sublimable dye is discharged by a liquid ejection head as a recording head and adhered to an intermediate transfer medium, and the surface of the intermediate transfer medium to which the ink composition is adhered and the fabric surface to which the treatment liquid composition is adhered are heated in a facing state, and the disperse dye contained in the ink composition is transferred to the fabric to which the treatment liquid composition is adhered. In this embodiment, such a printing method is also referred to as an indirect printing recording method. With this printing method, the form of the fabric is not limited, and good printing can be performed.

[0122] 6.2.1. Treatment Liquid Composition Adhesion Step Regarding the treatment liquid composition adhesion step, the above printing method can be referred to.

[0123] 6.2.2. Discharge Step In the discharge step, the heated ink composition is discharged from the liquid ejection head and adhered to the intermediate transfer medium. Specifically, the pressure generating means is driven to discharge the ink composition filled in the pressure generating chamber of the liquid ejection head from the nozzles.

[0124] As the intermediate transfer medium, for example, paper such as plain paper and a recording medium provided with an ink receiving layer can be used. The recording medium provided with the above ink receiving layer is called, for example, dedicated paper for inkjet and coated paper. Among them, paper provided with an ink receiving layer containing inorganic particles such as silica is more preferable. Thereby, in the process of drying the ink composition applied to the intermediate transfer medium, an intermediate recording material with suppressed bleeding or the like on the recording surface can be obtained. Also, with such a medium, it is easier to retain the disperse dye on the surface of the recording surface, and in the subsequent transfer step, the sublimation of the disperse dye can be performed more efficiently.

[0125] In this process, multiple types of ink compositions may be used. Thereby, for example, the color gamut that can be expressed can be made wider. Among the multiple types of ink compositions, one type may be the ink composition of the present embodiment, or two or more types may be the ink composition of the present embodiment.

[0126] 6.2.3. Transfer Process The transfer process is a process of heating with the surface of the intermediate transfer medium to which the ink composition adheres and the fabric surface to which the treatment liquid composition adheres facing each other, and transferring the disperse dye contained in the ink composition to the fabric to which the treatment liquid composition adheres. Thereby, the disperse dye is transferred, and an impression object which is a fabric to which the ink composition adheres is obtained.

[0127] In this process, the intermediate transfer medium to which the ink composition is applied may be heated in a state of facing the fabric to which the treatment liquid composition adheres. In this process, it is more preferable to heat in a state where the intermediate transfer medium and the fabric to which the treatment liquid composition adheres are in close contact. Thereby, for example, a clearer image can be recorded, that is, dyed, on the fabric to which the treatment liquid composition adheres.

[0128] Examples of the heating method include steaming by steam, heat press by dry heat, thermosol, HT steamer by superheated steam, and HP steamer by pressurized steam. The fabric to which the ink composition is applied may be immediately subjected to heat treatment, or heat treatment may be performed after a predetermined time has elapsed.

[0129] Since it tends to be difficult for pretreatment marks to remain on the fabric after dye printing, and a printed matter having more excellent color development properties and texture is likely to be obtained, as a heating method, heat pressing by dry heat is preferable. In heat pressing by dry heat, usually, during the heating, moisture contained in the fabric generates as steam from the unpressurized portion. At that time, carbonates of potassium carbonate salt and sodium carbonate salt generated in the fabric may localize in the unpressurized portion and appear as pretreatment marks on the fabric surface. However, since the total concentration of the treatment liquid composition of the present embodiment is 100.0 ppm or less, it is difficult for those carbonates to be generated in the fabric. Therefore, even when heat pressing by dry heat is used, it is difficult for pretreatment marks derived from carbonates to appear.

[0130] The heating temperature is preferably 160°C or higher and 220°C or lower, more preferably 190°C or higher and 210°C or lower. When the heating temperature is within the above range, the energy required for transfer can be reduced more, and the productivity of the printed matter tends to be more excellent. Also, the color development property of the printed matter tends to be more excellent.

[0131] The heating time depends on the heating temperature, but is preferably 30 seconds or longer and 120 seconds or shorter, more preferably 40 seconds or longer and 90 seconds or shorter. When the heating time is within the above range, the energy required for transfer can be reduced more, and the productivity of the printed matter tends to be more excellent. Also, the color development property of the printed matter tends to be more excellent.

[0132] By transfer, the adhesion amount of the ink composition adhering to the fabric is, for example, 1.5 mg / cm 2 or more and 6.0 mg / cm 2 or less per unit area of the fabric. When the adhesion amount of the ink composition is within the above range, the color development property of an image or the like formed by printing is improved, and the drying property of the ink adhering to the fabric is ensured, reducing the occurrence of bleeding of the image or the like.

[0133] 6.2.4. Other processes In this method, an intermediate treatment process and a post-treatment process may be included as necessary.

[0134] Examples of the intermediate treatment step include a step of preheating the fabric to which the treatment liquid composition has adhered. Examples of the post-treatment step include a step of washing the printed matter.

[0135] 6.3. Direct printing and dyeing recording method The inkjet printing and dyeing method may include a treatment liquid composition adhesion step of adhering a treatment liquid composition to a fabric, and an ink composition adhesion step of discharging an ink composition from a recording head and adhering the ink composition to the fabric to which the treatment liquid composition obtained by the treatment liquid composition adhesion step has adhered. In the present embodiment, such a printing and dyeing method is also referred to as a direct printing and dyeing recording method. With this printing and dyeing method, it is possible to easily and surely form a dyed portion of a fine pattern. In addition, since it is not necessary to use a plate such as an intermediate transfer medium, it has excellent on-demand properties and can be suitably applied to small-lot production and multi-item production.

[0136] 6.3.1. Step of obtaining a fabric to which a treatment liquid composition has adhered For the treatment liquid composition adhesion step, the above-described printing and dyeing method can be referred to.

[0137] 6.3.2. Ink composition adhesion step In the ink composition adhesion step, the ink composition is adhered to the fabric to which the treatment liquid composition has adhered. Further, the ink composition adhesion step may include a step of further adhering the ink composition onto the region to which the ink composition has adhered.

[0138] In the ink composition adhesion step, the maximum adhesion amount to the fabric is preferably 50 mg / cm 2 or more and 200 mg / cm 2 or less, and more preferably 80 mg / cm 2 or more and 150 mg / cm 2 or less. When the maximum adhesion amount is within the above range, the color development property becomes better. In addition, the friction fastness of the image is excellent, and the aggregation unevenness tends not to be noticeable.

[0139] In this process, when applying the ink composition to the fabric to which the treatment liquid composition has adhered, it is preferable to perform heating. Thereby, for example, a clearer image can be recorded, i.e., dyed, on the fabric to which the treatment liquid composition has adhered.

[0140] As the heating method, the method described in the drying step in the above-mentioned resist dyeing method can be referred to.

[0141] In heating, the surface temperature of the heated fabric is preferably 60°C or higher and 180°C or lower. By having the surface temperature within the above range, damage to the inkjet head and the fabric can be reduced, and at the same time, the ink is likely to uniformly wet and spread on the fabric and is likely to penetrate. Note that the surface temperature can be measured using, for example, a non-contact thermometer (product name "IT2-80", manufactured by Keyence Corporation).

[0142] The heating time is preferably 5 seconds or longer and 5 minutes or shorter. By having the heating time within the above range, it is possible to sufficiently heat the fabric while reducing damage to the inkjet head and the fabric.

[0143] 6.3.3. Other Processes In this method, an intermediate treatment step and a post-treatment step may be included as necessary. Regarding these steps, the other steps in the above-mentioned indirect resist dyeing recording method can be referred to.

Specifically, the following method was used to obtain a fabric with the treatment liquid composition attached. As the fabric, white cotton blade #4000 (product name, manufactured by Toyobo Co., Ltd.) was immersed in the treatment liquid composition, and the treatment liquid composition was applied to the fabric with a mangle roller so that the squeezing ratio was 80%. Thereafter, after drying at 140 °C for 2 minutes and further drying at 170 °C for 1 minute, fabrics with the treatment liquid composition attached were obtained respectively.
