Description

[Technical Field]

[0001] The present invention relates to a treatment liquid composition, a composition set, a treatment method, and a textile printing method. [Background technology]

[0002] In recent years, the applications of inkjet printing have expanded, and inkjet printing is now used not only in office and home printing machines but also in commercial printing, textile printing, and the like.

[0003] Inkjet inks containing sublimation dyes and disperse dyes that have sublimation properties are also used.

[0004] Such inkjet inks include a direct printing method in which the ink is applied to the fabric to be dyed and then the dye is fixed by heat treatment such as steaming, and a thermal transfer printing method in which the dye ink is applied to an intermediate transfer medium and then the dye is sublimated and transferred from the intermediate transfer medium to the fabric to be dyed by heat.

[0005] However, in the past, when dyeing with inkjet ink, the fabric had to be made of polyester fibers.

[0006] In order to obtain dyeability for fibers other than polyester fibers, particularly fabrics made of cellulosic fibers, a method has been proposed in which a fabric containing cellulosic fibers is treated with an alkaline aqueous solution and a non-aqueous solution containing an aromatic acylating agent, thereby promoting an aromatic acylation reaction (see Patent Document 1).

[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-123373 Summary of the Invention [Problem to be solved by the invention]

[0008] However, the above-mentioned methods sometimes fail to provide sufficient color development, and also require the use of a large amount of a highly concentrated strong alkali and an aromatic acylating agent such as benzoyl chloride, which is toxic and corrosive to the skin, resulting in problems in terms of safety and environmental impact. [Means for solving the problem]

[0009] The present invention has been made to solve the above-mentioned problems, and can be realized as the following application examples.

[0010] A treatment liquid composition according to an application example of the present invention is a treatment liquid composition that is applied to a fabric containing fibers having hydroxyl groups and is to be subjected to textile printing, and includes: an oxazoline group-containing polymer; and aromatic carboxylic acids.

[0011] In a treatment liquid composition according to another application example of the present invention, the oxazoline value of the oxazoline group-containing polymer is 100 or more and 600 or less.

[0012] In a treatment liquid composition according to another application example of the present invention, the content of the oxazoline group-containing polymer in the treatment liquid composition is 1.0% by mass or more and 10.0% by mass or less.

[0013] In a treatment liquid composition according to another application example of the present invention, the content of the aromatic carboxylic acids in the treatment liquid composition is 0.1% by mass or more and 20.0% by mass or less.

[0014] In a treatment liquid composition according to another application example of the present invention, the aromatic carboxylic acids are at least one selected from the group consisting of benzoic acid, 1-naphthalenecarboxylic acid, 2-naphthalenecarboxylic acid, and salts thereof.

[0015] In a treatment liquid composition according to another application example of the present invention, the oxazoline group-containing polymer is a resin having a styrene-acrylic structure.

[0016] In the treatment liquid composition according to another application example of the present invention, the glass transition temperature of the oxazoline group-containing polymer is 0° C. or higher.

[0017] Furthermore, in a treatment liquid composition according to another application example of the present invention, when the content of the oxazoline group-containing polymer in the treatment liquid composition is XP [mass %] and the content of the aromatic carboxylic acids in the treatment liquid composition is XA [mass %], the relationship of 0.1≦XP / XA≦40 is satisfied.

[0018] The composition set according to the application example of the present invention comprises: a treatment liquid composition according to the application example of the present invention; and an inkjet dye textile printing ink composition containing a dye and water. In a composition set according to another application example of the present invention, the dye is a disperse dye.

[0019] A treatment method according to an application example of the present invention includes a treatment liquid application step of applying a treatment liquid composition according to an application example of the present invention to a fabric containing fibers having hydroxyl groups.

[0020] A textile printing method according to an application example of the present invention includes an ink composition application step of applying an ink jet dye textile printing ink composition containing a dye and water to an intermediate transfer medium by an ink jet method to form an image; and a transfer step of heating the intermediate transfer medium and a treated fabric obtained by treating a fabric containing fibers having hydroxyl groups with a treatment liquid composition according to an application example of the present invention while they are facing each other, thereby transferring the image to the treated fabric. DETAILED DESCRIPTION OF THE INVENTION

[0021] Preferred embodiments of the present invention will be described in detail below. [1] Treatment liquid composition First, the treatment liquid composition of the present invention will be described.

[0022] The treatment liquid composition of the present invention is a treatment liquid composition to be applied to a fabric to be printed, particularly a fabric containing fibers having hydroxyl groups, and contains an oxazoline group-containing polymer and an aromatic carboxylic acid.

[0023] In this way, by containing an oxazoline group-containing polymer and aromatic carboxylic acids, a dehydration condensation reaction can occur between hydroxyl groups and oxazoline groups contained in the fibers constituting the fabric, and the oxazoline groups can react with the aromatic carboxylic acids. This allows aromatic functional groups derived from aromatic carboxylic acids to be introduced into the fabric. By introducing aromatic functional groups into the fabric in this way, the fabric generally has improved affinity with dyes having an aromatic ring structure, improved dyeability, and excellent color development. Furthermore, because the aromatic functional groups can be introduced into the fabric via a covalent bond with strong bonding strength, the dyed products obtained by printing also have excellent fastness. Furthermore, there is no need to use dangerous or highly toxic substances such as strong alkalis or aromatic acylating agents, which is advantageous in terms of safety and environmental impact. Furthermore, the method can be suitably applied to the production of dyed products using simple equipment and processes.

[0024] [1-1] Oxazoline group-containing polymer The treatment liquid composition of the present invention contains an oxazoline group-containing polymer. The oxazoline group-containing polymer is a component that mainly contributes to a reaction with hydroxyl groups contained in the fibers constituting the fabric and a reaction with aromatic carboxylic acids, and has the function of introducing an aromatic ring structure derived from aromatic carboxylic acids into the fibers.

[0025] The oxazoline group-containing polymer may be any polymer that contains an oxazoline group in the molecule, and the oxazoline value of the oxazoline group-containing polymer is preferably 100 or more and 600 or less, more preferably 200 or more and 590 or less, and even more preferably 300 or more and 580 or less.

[0026] This allows the above-mentioned reaction to proceed more suitably while ensuring that the texture of the dyed product obtained as a final product is sufficiently excellent, and makes it possible to improve the color development and fastness of the dyed product.

[0027] In this specification, the oxazoline value refers to a value expressed by X / Y, where X is the weight-average molecular weight of the oxazoline group-containing polymer and Y is the number of oxazoline groups contained in one molecule of the oxazoline group-containing polymer.

[0028] The oxazoline group-containing polymer may have any other chemical structure as long as it has an oxazoline group. For example, a resin having a styrene structure, a resin having an acrylic structure, a resin having a styrene-acrylic structure, etc. can be used. However, a resin having at least a styrene structure is preferred, and a resin having a styrene-acrylic structure is more preferred.

[0029] This allows fabric treated with the treatment liquid composition to have better dyeability and color development with dyes. This effect is particularly pronounced when a disperse dye is used as the dye. Furthermore, the presence of an acrylic structure in addition to a styrene structure enhances intermolecular interactions for dyeing with a disperse dye, resulting in better dyeability and color fastness.

[0030] As the oxazoline group-containing polymer, a combination of several materials may be used.

[0031] The glass transition temperature of the oxazoline group-containing polymer is not particularly limited, but is preferably 0° C. or higher.

[0032] This makes it possible to improve the fastness of dyed products produced using fabrics treated with the treatment liquid composition of the present invention.

[0033] In particular, the glass transition temperature of the oxazoline group-containing polymer is more preferably 10°C or higher and 100°C or lower, and even more preferably 30°C or higher and 80°C or lower.

[0034] This makes it possible to more significantly exhibit the above-mentioned effects, and also to improve the flexibility of the oxazoline group-containing polymer, thereby improving the texture of dyed products produced using fabrics treated with the treatment liquid composition of the present invention.

[0035] The content of the oxazoline group-containing polymer in the treatment liquid composition of the present invention is preferably 1.0% by mass or more and 10.0% by mass or less, more preferably 1.5% by mass or more and 9.0% by mass or less, and even more preferably 2.0% by mass or more and 7.0% by mass or less.

[0036] This allows the above-mentioned reaction to proceed more suitably while ensuring that the texture of the dyed product obtained as a final product is sufficiently excellent, and makes it possible to improve the color development and fastness of the dyed product.

[0037] [1-2] Aromatic carboxylic acids The treatment liquid composition of the present invention contains an aromatic carboxylic acid.

[0038] Aromatic carboxylic acids mainly react with the oxazoline groups of the oxazoline group-containing polymer, thereby functioning to introduce an aromatic ring structure into the fabric via the oxazoline group-containing polymer.

[0039] Aromatic carboxylic acids contain, in the molecule, an aromatic ring structure and at least one of a carboxyl group and a salt structure thereof.

[0040] Examples of the aromatic ring structure contained in the molecule of the aromatic carboxylic acids include hydrocarbon ring structures such as a benzene ring, a naphthalene ring, an anthracene ring, and an annulene ring, and heterocyclic structures such as a furan ring, a thiophene ring, a pyrrole ring, a pyrazole ring, an imidazole ring, a pyridine ring, a pyridazine ring, a pyrimidine ring, and a pyrazine ring.

[0041] The aromatic carboxylic acids may have a plurality of aromatic ring structures in the molecule. The carboxyl group and its salt structure may be directly bonded to the aromatic ring structure described above in the molecule of the aromatic carboxylic acid, or may be bonded to the aromatic ring via at least one other atom.

[0042] The aromatic carboxylic acids may have one or more carboxyl groups or salt structures thereof in the molecule.

[0043] The treatment liquid composition of the present invention may contain a plurality of types of aromatic carboxylic acids. The aromatic carboxylic acids contained in the treatment liquid composition of the present invention are preferably one or more selected from the group consisting of benzoic acid, 1-naphthalenecarboxylic acid, 2-naphthalenecarboxylic acid, and salts thereof, and more preferably one or more selected from the group consisting of benzoates, 1-naphthalenecarboxylates, and 2-naphthalenecarboxylates.

[0044] This makes it possible to improve the reactivity with the oxazoline group of the oxazoline group-containing polymer, and also improves the affinity between the fabric treated with the treatment liquid composition of the present invention, i.e., the treated fabric, and the dye, thereby further improving the dyeability and color development.

[0045] In particular, when the aromatic carboxylic acid is a salt, the solubility in water can be improved, the dissolution stability of the aromatic carboxylic acid in the treatment liquid composition of the present invention can be improved, and undesired precipitation of the aromatic carboxylic acid and undesired concentration variations in the treatment liquid composition of the present invention can be more effectively prevented. As a result, treatment of fabrics can be performed more stably, the color development and fastness of the final dyed product can be improved, and the occurrence of undesired color unevenness in the dyed product can be more effectively prevented. In addition, the storage stability of the treatment liquid composition of the present invention can be improved, and the treatment liquid composition of the present invention can be more suitably used for treating fabrics and producing dyed products even when stored for a long period of time.

[0046] When the aromatic carboxylic acids contained in the treatment liquid composition of the present invention are salts of carboxylic acids, examples of the salts include lithium salts, sodium salts, potassium salts, magnesium salts, calcium salts, and ammonium salts.

[0047] The content of aromatic carboxylic acids in the treatment liquid composition of the present invention is preferably 0.1% by mass or more and 20.0% by mass or less, more preferably 0.2% by mass or more and 9.0% by mass or less, and even more preferably 0.3% by mass or more and 5.0% by mass or less.

[0048] This allows the reaction between the aromatic carboxylic acid and the oxazoline group-containing polymer to proceed more suitably, reduces the amount of aromatic carboxylic acid remaining as an unreacted component after the reaction, and improves the color development of dyed products produced using the treatment liquid composition of the present invention.

[0049] When the content of the oxazoline group-containing polymer in the treatment liquid composition of the present invention is XP [mass %] and the content of aromatic carboxylic acids in the treatment liquid composition is XA [mass %], it is preferable to satisfy the relationship 0.1≦XP / XA≦40, it is more preferable to satisfy the relationship 0.4≦XP / XA≦30, and it is even more preferable to satisfy the relationship 2.0≦XP / XA≦10.

[0050] This allows the reaction between the aromatic carboxylic acid and the oxazoline group-containing polymer to proceed more suitably, and the amounts of aromatic carboxylic acids and unreacted oxazoline groups remaining as unreacted components after the reaction can be reduced, thereby making it possible to improve the color development of dyed items produced using the treatment liquid composition of the present invention.

[0051] [1-3]Water The treatment liquid composition of the present invention usually contains water in addition to the oxazoline group-containing polymer and aromatic carboxylic acids.

[0052] In the treatment liquid composition of the present invention, water is a component that mainly functions as a solvent and a dispersion medium for the oxazoline group-containing polymer and aromatic carboxylic acids. Furthermore, by including water in the treatment liquid composition of the present invention, treatment of fabrics with the treatment liquid composition of the present invention can be more suitably carried out. As the water, for example, pure water such as RO water, distilled water, or ion-exchanged water may be used.

[0053] The water content in the treatment liquid composition of the present invention is preferably 70.0% by mass or more and 98.9% by mass or less, more preferably 73.0% by mass or more and 97.0% by mass or less, and even more preferably 75.0% by mass or more and 96.0% by mass or less.

[0054] This makes it possible to more reliably adjust the viscosity and fluidity of the treatment liquid composition to suitable values, thereby enabling more suitable treatment of fabrics.

[0055] [1-4] Polyvalent carbodiimide compounds The treatment liquid composition of the present invention may further contain a polyvalent carbodiimide compound.

[0056] As a result, dyed products produced using fabric treated with the treatment liquid composition of the present invention will have better color development.

[0057] The polyvalent carbodiimide compound may be any compound having two or more carbodiimide structures, that is, —N═C═N— structures, in the molecule, and examples thereof include polycarbodiimide resins.

[0058] Commercially available polycarbodiimide compounds include, for example, V-02, V-02-L2, SV-02, V-04, V-10, SW-12G, E-02, E-03A, and E-05 (all manufactured by Nisshinbo Chemical Inc.).

[0059] The NCN equivalent of the polyvalent carbodiimide compound is preferably 600 or less, more preferably 100 or more and 580 or less, and even more preferably 200 or more and 550 or less.

[0060] This makes it possible to improve the storage stability of the treatment liquid composition of the present invention, while also improving the color development of dyed products produced using fabrics treated with the treatment liquid composition of the present invention.

[0061] In this specification, the NCN equivalent refers to a value expressed by X / Y, where X is the molecular weight of the polycarbodiimide compound and Y is the number of carbodiimide structures contained in one molecule of the polycarbodiimide compound.

[0062] The content of the polyvalent carbodiimide compound in the treatment liquid composition of the present invention is preferably 0.1% by mass or more and 20.0% by mass or less, more preferably 0.5% by mass or more and 15.0% by mass or less, and even more preferably 0.8% by mass or more and 7.0% by mass or less.

[0063] This makes it possible to improve the storage stability of the treatment liquid composition of the present invention, while also improving the color development of dyed products produced using fabrics treated with the treatment liquid composition of the present invention.

[0064] When the content of the oxazoline group-containing polymer in the treatment liquid composition of the present invention is XP [mass %] and the content of the polyvalent carbodiimide compound in the treatment liquid composition is XC [mass %], it is preferable to satisfy the relationship 0.01≦XC / XP≦10.0, it is more preferable to satisfy the relationship 0.05≦XC / XP≦5.0, and it is even more preferable to satisfy the relationship 0.10≦XC / XP≦2.5.

[0065] This makes it possible to improve the storage stability of the treatment liquid composition of the present invention, while also improving the color development of dyed products produced using fabrics treated with the treatment liquid composition of the present invention.

[0066] [1-5]Non-aromatic organic acid The treatment liquid composition of the present invention may further contain a non-aromatic organic acid.

[0067] This makes it possible to ensure that the dyeability and fastness of dyed items produced using the treatment liquid composition of the present invention are sufficiently excellent, while more effectively suppressing undesired yellowing and the like of fabrics treated with the treatment liquid composition of the present invention, i.e., treated fabrics, and dyed items produced using the treatment liquid composition of the present invention.

[0068] The non-aromatic organic acid may be any acid that does not have an aromatic ring structure in the molecule, and examples thereof include acetic acid, malic acid, citric acid, adipic acid, succinic acid, lactic acid, N,N-bis(2-hydroxyethyl)-2-aminoethanesulfonic acid (BES), 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES), morpholinoethanesulfonic acid (MES), carbamoylmethyliminobisacetic acid (ADA), piperazine-1,4-bis(2-ethanesulfonic acid) (PIPES), N-(2-acetamido)-2-aminoethanesulfonic acid (ACES), cholamine hydrochloride, and N-tris(hydroxymethyl)methyl-2-aminoethanesulfonic acid (TES). Among these, at least one selected from the group consisting of acetic acid, malic acid, and citric acid is preferred.

[0069] This allows the effects of using the non-aromatic organic acid to be more pronounced.

[0070] The content of the non-aromatic organic acid in the treatment liquid composition of the present invention is preferably 0.01% by mass or more and 0.5% by mass or less, more preferably 0.02% by mass or more and 0.4% by mass or less, and even more preferably 0.03% by mass or more and 0.3% by mass or less. This makes the above-mentioned effects more pronounced.

[0071] [1-6] Other ingredients The treatment liquid composition of the present invention may contain components other than those described above. Hereinafter, such components will also be referred to as "other components" in this section.

[0072] Examples of other components include chelating agents, preservatives, mildew inhibitors, rust inhibitors, flame retardants, various dispersants, water-soluble organic solvents, surfactants, antioxidants, ultraviolet absorbers, oxygen absorbers, dissolution aids, and penetrating agents.

[0079] The composition set of the present invention comprises the treatment liquid composition of the present invention described above, and an inkjet dye textile printing ink composition containing a dye and water.

[0080] This makes it possible to provide a composition set that can be suitably used for producing dyed products with excellent color development and fastness. Furthermore, it is advantageous in terms of safety and environmental impact, as it does not require the use of dangerous or highly toxic substances such as strong alkalis or aromatic acylating agents. Furthermore, it can be suitably applied to the production of dyed products using simple equipment and processes.

[0081] The treatment liquid compositions constituting the composition set of the present invention have been explained above in [1], so the inkjet dye textile printing ink composition will be explained below.

[0082] [2-1] Inkjet dye textile printing ink composition The inkjet dye textile printing ink compositions constituting the composition set of the present invention contain a dye and water.

[0092] In particular, the dye contained in the ink jet dye textile printing ink composition constituting the composition set of the present invention is preferably a disperse dye. This allows the effects of the present invention to be more pronounced.

[0093] The content of the colorant in the inkjet dye textile printing ink composition is not particularly limited, but is preferably from 1.0 to 10.0% by mass, and more preferably from 1.0 to 8.0% by mass.

[0094] This makes it easier to ensure sufficient color density in a recording section formed using the inkjet dye textile printing ink composition, and also makes it possible to improve the high-temperature stability, storage stability, ejection stability, clogging recovery properties, etc. of the inkjet dye textile printing ink composition.

[0095] [2-1-2]Water The ink jet dye textile printing ink composition constituting the composition set of the present invention contains water.

[0096] Water is a component that functions, for example, as a solvent for dissolving solid components such as dyes and a dispersion medium for dispersing them in the inkjet dye printing ink composition. As the water, for example, pure water such as RO water, distilled water, or ion-exchanged water may be used.

[0097] The water content in the inkjet dye textile printing ink composition is preferably 50.0% by mass or more and 98.0% by mass or less, more preferably 55.0% by mass or more and 95.0% by mass or less, and even more preferably 60.0% by mass or more and 92.0% by mass or less.

[0098] This makes it possible to more reliably adjust the viscosity of the inkjet dye textile printing ink composition to a suitable value, and further improves the ejection stability when using an inkjet method.

[0099] [2-1-3] Water-soluble organic solvents The inkjet dye textile printing ink composition constituting the composition set of the present invention may contain a water-soluble organic solvent.

[0100] This can improve the moisture retention of the inkjet dye textile printing ink composition and more effectively prevent the solid content of the inkjet dye textile printing ink composition from unintentionally precipitating due to drying in an inkjet head or the like. Furthermore, the viscosity of the inkjet dye textile printing ink composition can be more suitably adjusted. This further improves the ejection stability of the inkjet dye textile printing ink composition when used in an inkjet method.

[0101] The water-soluble organic solvent may be any organic solvent that is soluble in water, and for example, an organic solvent having a solubility in water at 20° C. of 10 g / 100 g water or more can be suitably used.

[0102] The boiling point of the water-soluble organic solvent at 1 atmospheric pressure is preferably 150°C or higher and 350°C or lower.

[0103] This can further improve the moisture retention of the inkjet dye textile printing ink composition, and more effectively prevent the solid content of the inkjet dye textile printing ink composition from unintentionally precipitating due to drying in an inkjet head, etc. As a result, the ejection stability of the inkjet dye textile printing ink composition when used in an inkjet method can be further improved. Furthermore, after the inkjet dye textile printing ink composition is ejected, it can be relatively easily volatilized as needed, and more effectively prevent the water-soluble organic solvent from unintentionally remaining in the dyed product produced.

[0104] Examples of such water-soluble organic solvents include alkyl monoalcohols; alkyl diols; glycerin; glycols; glycol monoethers; lactams, and one or more selected from these can be used in combination.

[0105] Examples of glycols include triethanolamine, ethylene glycol, diethylene glycol, triethylene glycol, and propylene glycol. Examples of glycol monoethers include triethylene glycol monobutyl ether. Examples of lactams include 2-pyrrolidone and 1-(2-hydroxyethyl)-2-pyrrolidone.

[0106] The content of the water-soluble organic solvent in the inkjet dye textile printing ink composition is preferably 1.0% by mass or more and 50.0% by mass or less, more preferably 3.0% by mass or more and 45.0% by mass or less, and even more preferably 5.0% by mass or more and 40.0% by mass or less.

[0107] This makes it possible to more reliably adjust the viscosity of the inkjet dye textile printing ink composition to a suitable value, thereby further improving the ejection stability when using an inkjet method.

[0108] [2-1-4] Surfactants The ink jet dye textile printing ink composition constituting the composition set of the present invention may contain a surfactant.

[0109] Examples of surfactants include various anionic surfactants, cationic surfactants, nonionic surfactants, etc., and one or more selected from these can be used in combination.

[0110] The content of the surfactant in the inkjet dye textile printing ink composition is preferably 0.1% by mass or more and 2.5% by mass or less, more preferably 0.1% by mass or more and 2.0% by mass or less, and even more preferably 0.1% by mass or more and 1.5% by mass or less.

[0111] [2-1-5] Resin materials The inkjet dye textile printing ink composition constituting the composition set of the present invention may contain a resin material.

[0112] This makes it possible to improve the fixability of the dye-recorded area and the fastness of the dyed product when producing a dyed product by the second method described below.

[0113] As the resin material, for example, polyester resin, urethane resin, acrylic styrene copolymer resin, etc. can be used.

[0114] The content of the resin material in the inkjet dye textile printing ink composition is preferably 0.1% by mass or more and 15.0% by mass or less, more preferably 0.5% by mass or more and 10.0% by mass or less, and even more preferably 0.5% by mass or more and 8.0% by mass or less.

[0115] This makes it possible to improve the fastness of the dyed product while ensuring that the texture of the dyed product obtained is sufficiently excellent.

[0116] [2-1-6] Other ingredients The inkjet dye textile printing ink compositions constituting the composition set of the present invention may contain components other than the components described above. Hereinafter, such components will also be referred to as "other components" in this section.

[0117] Examples of other components include chelating agents, preservatives, mildew inhibitors, rust inhibitors, flame retardants, various dispersants, antioxidants, ultraviolet absorbers, oxygen absorbers, dissolution aids, and penetrating agents.

[0118] Examples of chelating agents include ethylenediaminetetraacetate, etc. Examples of preservatives and antifungal agents include sodium benzoate, sodium pentachlorophenol, sodium 2-pyridinethiol-1-oxide, sodium sorbate, sodium dehydroacetate, 1,2-dibenzisothiazolin-3-one, 4-chloro-3-methylphenol, etc. Examples of rust inhibitors include benzotriazole, etc.

[0119] The content of other components is preferably 5.0% by mass or less, and more preferably 1.0% by mass or less.

[0120] [2-1-7]Other The surface tension at 25°C of the inkjet dye textile printing ink composition constituting the composition set of the present invention is not particularly limited, but is preferably 20 mN / m or more and 60 mN / m or less, more preferably 25 mN / m or more and 50 mN / m or less, and even more preferably 30 mN / m or more and 40 mN / m or less.

[0121] This makes it more difficult for nozzle clogging of the inkjet head to occur, further improving the ejection stability of the inkjet dye textile printing ink composition. Furthermore, even if nozzle clogging does occur, recovery by capping the nozzle can be more excellent.

[0122] The surface tension can be measured by the Wilhelmy method or the Ring method using a surface tensiometer (e.g., DY-300, DY-500, DY-700, etc., manufactured by Kyowa Interface Science Co., Ltd.).

[0123] The viscosity at 25°C of the inkjet dye textile printing ink composition constituting the composition set of the present invention is preferably 2 mPa·s or more and 10 mPa·s or less, and more preferably 3 mPa·s or more and 8 mPa·s or less.

[0124] This improves the ejection stability of the inkjet dye textile printing ink composition when used in an inkjet method.

[0125] The viscosity can be determined by measurement using a vibration viscometer, a rotational viscometer, a capillary viscometer, or a falling ball viscometer. For example, when using a vibration viscometer, the viscosity can be determined by measurement in accordance with JIS Z8809.

[0126] The inkjet dye textile printing ink composition constituting the composition set of the present invention may be any composition that can be ejected by an inkjet method. Examples of the inkjet method include on-demand methods such as a charge deflection method, a continuous method, a piezoelectric method, and a Bubble Jet (registered trademark) method. However, it is particularly preferable that the inkjet dye textile printing ink composition be ejected from an inkjet head that uses a piezoelectric vibrator.

[0127] This makes it possible to more effectively prevent the coloring material from being altered in the inkjet head, and to improve the ejection stability by the inkjet method.

[0128] [2-2] Other The composition set of the present invention may include at least one treatment liquid composition and at least one inkjet dye textile printing ink composition of the present invention. In other words, the composition set of the present invention may include multiple types of treatment liquid compositions or multiple types of inkjet dye textile printing ink compositions of the present invention.

[0129] The composition set of the present invention preferably includes three inkjet dye textile printing ink compositions corresponding to the three primary colors, i.e., cyan, magenta, and yellow. The three primary colors may be further subdivided based on their color densities. For example, in addition to cyan, magenta, and yellow, the composition set may include light cyan, light magenta, and light yellow.

[0130] The composition set of the present invention may also include an achromatic inkjet dye textile printing ink composition, more specifically, a black ink.

[0131] Furthermore, the composition set of the present invention may include, in addition to the treatment liquid composition and the inkjet dye textile printing ink composition of the present invention, compositions other than these.

[0132] [3] Processing method Next, the processing method of the present invention will be described.

[0133] The treatment method of the present invention, that is, the method for producing a treated fabric, includes a treatment liquid application step in which the treatment liquid composition of the present invention described above is applied to a fabric containing fibers having hydroxyl groups.

[0134] This provides a treatment method that can produce treated fabrics suitable for use in the production of dyed products with excellent color development and fastness. Furthermore, it is advantageous in terms of safety and environmental impact because it does not require the use of dangerous or highly toxic substances such as strong alkalis or aromatic acylating agents. Furthermore, the method can be suitably applied to the production of treated fabrics and dyed products using simple equipment and processes.

[0135] [3-1]Fabric The fabric to which the treatment liquid composition of the present invention is applied will be described below.

[0136] The fabric may be any fabric containing fibers having hydroxyl groups. Examples of such fibers include synthetic fibers such as polyester fibers, semi-synthetic fibers such as acetate fibers, regenerated fibers such as cellulose fibers such as rayon, and natural fibers such as cotton, silk, and wool. Blends of two or more fibers selected from these may also be used. Blends of fibers having hydroxyl groups and fibers not having hydroxyl groups may also be used. Cotton is particularly preferred as the fiber having hydroxyl groups. When the fiber having hydroxyl groups is cotton, the use of the treatment liquid composition of the present invention can particularly improve the dyeability of disperse dyes on cotton, resulting in excellent color development.

[0137] As the fabric, various woven fabrics such as plain weave, twill weave, satin weave, varied plain weave, varied twill weave, varied satin weave, patterned weave, single-layer weave, double weave, multiple weave, warp pile weave, weft pile weave, and leno weave can be used.

[0138] The thickness of the fibers constituting the fabric can be, for example, 10 d or more and 100 d or less.

[0139] [3-2] Treatment liquid application process In the treatment liquid application step, the treatment liquid composition of the present invention described above is applied to a fabric containing fibers having hydroxyl groups.

[0140] In this step, the treatment liquid composition may be applied to the entire fabric or may be applied selectively to only a portion of the fabric, but it is preferable to apply the treatment liquid composition to at least the entire area to be dyed.

[0141] In this step, the treatment liquid composition may be applied to the fabric by any method, and examples of methods for applying the treatment liquid composition to the fabric include immersion, spraying, and ink-jet methods.

[0142] This step may be carried out, for example, with the treatment liquid composition in a heated state. This allows, for example, when the treatment liquid composition contains solid components with low solubility, the solid components to be more suitably dissolved, and also allows the treatment liquid composition to more easily penetrate into the gaps between the fibers of the fabric, so that the surfaces of the fibers that make up the fabric can be suitably wetted with the treatment liquid composition.As a result, the effects of the present invention can be more significantly exhibited.

[0143] The temperature of the treatment liquid composition in this step is not particularly limited, but is preferably 10°C or higher and 90°C or lower, more preferably 15°C or higher and 80°C or lower, and even more preferably 20°C or higher and 70°C or lower.

[0144] The amount of the treatment liquid composition applied to the fabric in this step is not particularly limited, but is preferably 50% to 200% of the mass of the fabric before the treatment liquid composition is applied.

[0145] This allows the above-mentioned reaction to proceed more favorably, and also simplifies the process of removing excess treatment liquid composition and its components.

[0146] The amount of the treatment liquid composition applied to the fabric may be adjusted by first applying an excess amount of the treatment liquid composition to the fabric, and then pressing, etc. More specifically, for example, the fabric may be immersed in the treatment liquid composition, and then pressed with a mangle roller to achieve a predetermined wringing ratio.

[0147] The above-mentioned wringing rate T [%] can be expressed as T = [(X1 - X0) / X0] × 100, where X0 [kg] is the mass of the fabric before the application of the treatment liquid composition and X1 [kg] is the mass of the fabric after the application of the treatment liquid composition, i.e., the mass of the fabric at the end of this process.

[0148] [3-3] Reaction process The treatment method of the present invention may include, after the treatment liquid application step, a reaction step in which the fibers constituting the fabric to which the treatment liquid composition has been applied are reacted with an oxazoline group-containing polymer and an aromatic carboxylic acid.

[0149] It should be noted that if the desired reaction proceeds sufficiently after the treatment liquid application step, there is no need to provide a separate reaction step, and this step may be omitted.

[0150] The reaction step can be suitably carried out by, for example, a heat treatment. This allows the reaction described above to proceed, and also allows volatile components such as water to be suitably removed, making it easier to handle the fabric thereafter, and also effectively preventing undesired bleeding of the inkjet dye textile printing ink composition when the inkjet dye textile printing ink composition is applied to the fabric that has been treated with the treatment liquid composition of the present invention.

[0151] When the reaction step is carried out by heat treatment, the heating temperature is preferably 70°C or higher and 250°C or lower, more preferably 80°C or higher and 220°C or lower, and even more preferably 100°C or higher and 200°C or lower.

[0152] This allows the above-mentioned reaction to proceed more efficiently while effectively preventing undesired denaturation and deterioration of the fabric and the components of the treatment liquid composition. It also allows volatile components such as water contained in the fabric to which the treatment liquid composition has been applied to be efficiently removed. This is also preferable from the viewpoint of energy conservation.

[0153] When the reaction step is carried out by heat treatment, the heating time is preferably from 20 seconds to 1200 seconds, more preferably from 30 seconds to 600 seconds, and even more preferably from 60 seconds to 300 seconds.

[0154] This allows the above-mentioned reaction to proceed more efficiently while effectively preventing undesired denaturation and deterioration of the fabric and the components of the treatment liquid composition. It also allows volatile components such as water contained in the fabric to which the treatment liquid composition has been applied to be efficiently removed. This is also preferable from the viewpoints of productivity of the treated fabric and energy conservation.

[0155] The reaction process may be carried out in multiple stages under different conditions. More specifically, the reaction step may include, for example, a first heat treatment mainly for the purpose of removing moisture and a second heat treatment mainly for the purpose of the above-mentioned reaction.

[0156] In such a case, the heating temperature in the first heat treatment is preferably 70°C or higher and 160°C or lower, more preferably 80°C or higher and 150°C or lower, and even more preferably 100°C or higher and 140°C or lower.

[0157] The heating time in the first heat treatment is preferably 10 seconds or more and 600 seconds or less, more preferably 15 seconds or more and 300 seconds or less, and even more preferably 30 seconds or more and 180 seconds or less.

[0158] The heating temperature in the second heat treatment is preferably 120°C or higher and 250°C or lower, more preferably 130°C or higher and 220°C or lower, and even more preferably 140°C or higher and 200°C or lower.

[0159] The heating time in the second heat treatment is preferably 10 seconds or more and 600 seconds or less, more preferably 15 seconds or more and 300 seconds or less, and even more preferably 30 seconds or more and 180 seconds or less.

[0160] [3-4] Cleaning process The treatment method of the present invention may include a washing step of washing the fabric after the treatment liquid application step, more specifically, for example, after the above-mentioned reaction step.

[0161] This makes it possible to remove, for example, unreacted components and unnecessary components from the fabric, and to more suitably dye the fabric with the inkjet dye textile printing ink composition.

[0162] Examples of the washing step include alkali washing, acid washing, water washing, and organic solvent washing, and two or more types selected from these may be used in combination.

[0163] In the washing step, when at least washing with water is performed, the washing with water is preferably performed using running water.

[0164] [3-5] Drying process Furthermore, the treatment method of the present invention may include a drying step of drying the fabric after the treatment liquid application step, more specifically, for example, after the above-mentioned washing step.

[0165] This makes it easier to handle the fabric thereafter, and also makes it possible to effectively prevent undesired bleeding of the inkjet dye printing ink composition when the inkjet dye printing ink composition is applied to the fabric that has been treated with the treatment liquid composition of the present invention.

[0166] The drying step can be suitably carried out by, for example, a heat treatment. This allows, for example, the above-mentioned reaction, particularly the reaction between the fibers constituting the fabric and the oxazoline group-containing polymer, to proceed further, increasing the number of reaction sites between the fibers and the oxazoline group-containing polymer and improving the bonding strength between the fibers and the oxazoline group-containing polymer.

[0167] The heating temperature in the drying step is preferably 100°C or higher and 200°C or lower, and more preferably 100°C or higher and 140°C or lower.

[0168] The heating time in the drying step is preferably 15 seconds or more and 300 seconds or less, and more preferably 30 seconds or more and 180 seconds or less.

[0169] [4] Printing method Next, the textile printing method of the present invention will be described.

[0170] [4-1] First method The textile printing method of the present invention, i.e., the method for producing a dyed product, comprises an ink composition application step of applying an inkjet dye textile printing ink composition containing a dye and water to an intermediate transfer medium by an inkjet method to form an image, and a transfer step of heating the intermediate transfer medium and a treated fabric obtained by treating a fabric containing fibers having hydroxyl groups with the treatment liquid composition of the present invention while they are placed opposite each other, thereby transferring the image to the treated fabric.

[0171] This makes it possible to provide a textile printing method capable of producing dyed products with excellent color development and fastness. Furthermore, it is not necessary to use highly dangerous or toxic substances such as strong alkalis or aromatic acylating agents, which is advantageous in terms of safety and environmental impact. Furthermore, the method can be suitably applied to the production of dyed products using simple equipment and processes.

[0172] [4-1-1] Ink composition application process In the ink composition application step, an ink jet dye textile printing ink composition containing a dye and water is applied to an intermediate transfer medium by an ink jet method to form an image. A plurality of ink jet textile printing ink compositions, for example, a plurality of ink jet dye textile printing ink compositions, may be used to form the image.

[0173] The inkjet method for ejecting the inkjet dye textile printing ink composition may be any method, including, for example, a charge deflection method, a continuous method, a piezo method, an on-demand method such as a bubble jet (registered trademark) method, and the like.

[0174] As the intermediate transfer medium, for example, paper such as plain paper, a recording medium provided with an ink receiving layer, such as recording media called inkjet paper or coated paper, etc. can be used.

[0175] [4-1-2] Transfer process In the transfer step, the intermediate transfer medium and a treated fabric obtained by treating a fabric containing fibers having hydroxyl groups with the treatment liquid composition of the present invention are placed opposite each other and heated to transfer the image to the treated fabric.

[0176] As the treated fabric, a treated fabric obtained by the treatment method described in [4] above can be used.

[0177] The heating temperature in this step is not particularly limited, but is preferably 160°C or higher and 230°C or lower, and more preferably 170°C or higher and 210°C or lower.

[0178] This allows the energy required for transfer to be reduced, leading to improved productivity of dyed products, and also to improved color development and fastness of the resulting dyed products.

[0179] The heating time in this step depends on the heating temperature, but is preferably 30 seconds or more and 90 seconds or less, and more preferably 30 seconds or more and 60 seconds or less.

[0180] This allows the energy required for transfer to be reduced, leading to improved productivity of dyed products, and also to improved color development and fastness of the resulting dyed products.

[0181] Furthermore, this step may be carried out by heating the surface of the intermediate transfer medium, on which the inkjet dye textile printing ink composition is adhered, while the surface is opposed to the treated fabric at a fixed distance, or by heating the surface of the intermediate transfer medium while it is in close contact with the surface of the treated fabric. However, it is preferable to carry out this step by heating the surface of the intermediate transfer medium, on which the inkjet dye textile printing ink composition is adhered, while it is in close contact with the surface of the treated fabric.

[0182] This can reduce the energy required for transfer, improve the productivity of dyed products, and improve the color development of the resulting dyed products.

[0183] [4-2] Second method The dyed product according to the present invention can also be produced, for example, by the following method.

[0184] That is, the dyed product according to the present invention can be suitably produced by using the second method, which includes an ink composition application step of applying an inkjet dye printing ink composition containing a dye and water to a treated fabric obtained by treating a fabric containing fibers having hydroxyl groups with the treatment liquid composition of the present invention, thereby forming an image, and a fixing step of heating the treated fabric on which the image has been formed, thereby fixing the image.

[0185] According to such a method, there is no need to use an intermediate transfer medium, and therefore it is advantageous from the viewpoints of productivity of dyed products, resource saving, and energy saving.

[0186] The processing temperature in the fixing step is not particularly limited, but is preferably 160°C or higher and 200°C or lower, and more preferably 170°C or higher and 185°C or lower.

[0187] This makes it possible to more effectively prevent undesired alteration, deterioration, etc. of the treated fabric and the components of the inkjet dye printing ink composition, while more efficiently fixing the dye.

[0188] The processing time of the fixing step is not particularly limited, but is preferably 30 seconds or more and 180 seconds or less, and more preferably 40 seconds or more and 120 seconds or less.

[0189] This makes it possible to improve the dyeability of the dye on the treated fabric and also improve the productivity of dyed products.

[0190] Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these.

[0191] For example, the processing method and printing method of the present invention may include steps other than those described above, if necessary.

[0192] Furthermore, in the above-described embodiment, the explanation has been centered on the case where the treatment liquid composition of the present invention contains water in addition to the oxazoline group-containing polymer and the aromatic carboxylic acid, but the treatment liquid composition of the present invention may contain a solvent or dispersion medium other than water instead of water.

[0204] [7] Manufacturing of dyed goods Dyed items were produced using the treatment liquid composition of Example 1 as follows.

[0205] First, the treatment liquid composition of Example 1 and the three inkjet dye textile printing ink compositions prepared in [6] above were combined to form a composition set.

[0206] Next, cotton broadcloth (#4000) manufactured by Nisshinbo Co., Ltd. was prepared as a fabric and immersed in the treatment liquid composition of Example 1 above.

[0207] Next, the amount of treatment liquid composition applied to the fabric was adjusted so that the wringing rate was 80% using a mangle roller, and the fabric was heat treated at 120°C for 2 minutes, and then further heat treated at 170°C for 1 minute.

[0208] Thereafter, the fabric was washed with water for 5 minutes and then dried to obtain a treated fabric.

[0209] On the other hand, using an inkjet printer (PX-G930 manufactured by Seiko Epson Corporation), the three inkjet dye textile printing ink compositions constituting the composition set according to Example 1 were ejected by inkjet printing onto the coated surface of coated paper (TRANSJET Sportsline 1254 manufactured by Cham Paper Co., Ltd.) serving as an intermediate transfer medium, to form an image having three areas in which the three inkjet dye textile printing ink compositions were applied independently without overlapping. Each of the three areas was printed at a resolution of 720 dpi horizontally and 720 dpi vertically, with a 100% duty and an ink application rate of 12 mg / inch. 2 The fill pattern was set to the following conditions.

[0210] The intermediate transfer medium on which the image was formed and the treated fabric were placed opposite each other, and a heat press (TP-608M, manufactured by Taiyo Seiki Co., Ltd.) was used to press the intermediate transfer medium at 200°C for 60 seconds under a pressure of 4.2 N / cm. 3 The image formed on the intermediate transfer medium was thermally transferred to the treated fabric by heating and pressing at a pressure of 1000 kJ / cm2, thereby obtaining a dyed evaluation sample. At this time, the intermediate transfer medium was placed so that the surface on which the image was formed faced the treated fabric.

[0211] Furthermore, dyed products were produced in the same manner as above, except that the treatment liquid composition of Example 1 was replaced with the treatment liquid compositions of Examples 2 to 22 and Comparative Example 1.

[0212] A dyed product was produced in the same manner as above, except that the treated fabric was replaced with a cotton broadcloth (#4000) manufactured by Nisshinbo Co., Ltd., which was a fabric not treated with the treatment liquid composition.

Specifically, each of the dyed products was left to stand for 1 hour at 25°C after production, and the recorded surface of the dyed product was rubbed 20 times with a cotton cloth under a load of 200g using a Gakushin-type rub fastness tester AB-301 (manufactured by Tester Sangyo Co., Ltd.). The state of peeling of the recorded surface and the state of ink transfer to the cotton cloth were then visually inspected, and the rub resistance was evaluated according to the following criteria. The less color transfer and peeling, the better the rub resistance, and the better the fastness. A grade of B or higher was considered good.
