Description

  The present invention relates to an ink jet printer provided with a conveying device having an adhesive endless conveying member and a recorded matter produced using the same.

  The ink jet recording method can easily and inexpensively create an image, and thus has been applied to various printing fields such as photographs, various printing, marking, and special printing such as a color filter. In particular, ink jet recording devices that emit and control fine dots, ink with improved color reproduction gamut, durability, and emission suitability, ink absorbency, coloring material color development, surface gloss, etc. are dramatically improved. In addition, it is also possible to obtain image quality comparable to silver salt photographs by using special inkjet paper. The image quality improvement of today's ink jet recording system is achieved only when all of the ink jet recording apparatus, ink, and ink jet dedicated paper are available.

  Furthermore, in recent years, it has been attempted to apply the above-described ink jet recording method to textile printing. This is because, in the field of textile printing, an ink jet recording method that does not require a plate making process has great advantages for shortening the delivery time and dealing with a small number of products.

  Further, since only a necessary amount of ink is used as a formed image, it can be said that this is an excellent image forming method having environmental advantages such as less waste liquid compared to the conventional method.

  In the ink jet textile printing method, it is necessary to stably transport a recording material that easily undergoes non-uniform deformation during transportation, such as a fabric, without causing deformation, for example, Adhesive transport belts are used.

  As such an adhesive transport belt, for example, a method of applying an organic solvent solution of an adhesive called a base adhesive on the transport belt to form an adhesive belt has been proposed (see, for example, Patent Document 1). . However, since an organic solvent is used for coating, there are problems in safety and environmental suitability for workers. Furthermore, when the adhesive strength is reduced due to repeated use, it is necessary to reapply the base adhesive, and after the adhesive has been scraped off once using an organic solvent, there is the trouble of applying again. there were.

  On the other hand, a method of applying an adhesive tape having an adhesive layer on both surfaces of a base material on the surface of an endless belt has been proposed (see, for example, Patent Document 2). As proposed in Patent Document 2, by using a double-sided adhesive tape, an adhesive layer can be provided on the belt without using an organic solvent or the like, and it can be easily replaced when the adhesive layer deteriorates. It becomes possible.

However, when an adhesive tape is to be applied on the conveyor belt without any gap, an overlapped portion A is generated between the ends of the adhesive tape as shown in FIG. That is, when the adhesive tape T is applied on the endless transport belt B, and when the adhesive tape T is applied to the entire circumference of the transport belt B, the adhesive tape T application start portion TS and the adhesive tape T are always applied. An overlapping portion A with the end point TE occurs. In this overlapping portion A, the cross section of the adhesive tape T is more exposed. In particular, when the adhesive layer 2 is provided on both surfaces of the substrate T as shown in FIG. After removing the peelable body 1 on both sides of the double-sided adhesive tape T, it is used by being attached to the base material T in a state composed of the base material T and the adhesive layer 2. Although I is applied, the solvent in the ink I penetrates to the double-sided pressure-sensitive adhesive tape T, and as a result, deformation 3 ′ of the base material and peeling of the pressure-sensitive adhesive layer 2 from the base material 3 occur. In addition, if ink enters the gap created by the deformation, even if cleaning is performed after that, the ink that has penetrated will not be removed. As a result, there was a problem that the product was no longer usable.

It is possible to provide an ink jet printer that prevents deformation, image reproducibility, backside contamination during printing, and image bleeding, and a recorded matter produced using the same.

  Hereinafter, the best mode for carrying out the present invention will be described in detail.

  As a result of intensive studies in view of the above problems, the present inventor has found that in an ink jet printer used in an ink jet recording method for ejecting and recording ink on a recording material, the recording material transport device uses an adhesive tape as an endless belt. Or an adhesive endless conveying member provided with an adhesive layer formed by transferring to the roller surface, and an ink jet printer characterized in that the adhesive tape does not have a base material, without requiring an organic solvent, In addition, the present inventors have found that an inkjet printer that can prevent deformation of the overlapped portion by ink, image reproducibility, backside contamination during printing, and image bleeding can be realized, and the present invention has been achieved.

  The ink jet printer of the present invention is used in an ink jet recording method for recording an image by emitting ink to a recording material.

  First, an outline of the ink jet printer of the present invention will be described using an ink jet textile printer as an example.

  FIG. 3 is a schematic diagram showing an embodiment of an ink jet printer as an example of an industrial ink jet recording apparatus in the present invention. Hereinafter, the schematic configuration of the ink jet printer of the present invention will be described with reference to FIG. 3. However, the ink jet printer to which the present invention can be applied is not limited to the following configuration, and is an industrial ink jet recording means. Therefore, it is possible to add any structural change or component easily conceivable by those skilled in the art.

  As shown in FIG. 3, a print medium that is a recording material in the ink jet printer P of the present invention is an appropriate fabric 51 and is wound as a roll-shaped laminate 50. The fabric 51 is unloaded from the roll-shaped laminate, and is pressed against the surface of the adhesive conveyance belt 59 via the intermediate rollers 53 and 54 and the tension roller 52 and fixed by the printing pressure roller 55. The fixed fabric 51 is transported in the transport direction indicated by the arrow, and is printed with the ink applied by the printer unit having the inkjet print head 56 in the region between the platen rollers 57.

  The printed fabric 51 is peeled off from the adhesive conveying belt 59 by the nail 60 for peeling off the cloth, and dried by the drying heater 64. As the drying heater 64, it is possible to select and use one having an appropriate form, such as one that blows hot air against the fabric 51, one that is dried by irradiating infrared rays. After drying, the film is taken up by a take-up roller 66.

  The fabric transport member S includes a transport roller 58, a transport belt 59 in the form of an endless belt that is a transport means wound between the transport rollers 58, and a pair of platen rollers 57 that regulate the printing surface of the fabric 51 to be flat. And have. In the transport belt 59, the ink is roughly wiped off by the cleaning member 61 after the fabric 51 is peeled off at the site of the cloth peeling claw 60. Next, after the cleaning member 62 is washed with water and the moisture is wiped off by the wiping member 63, the cloth 51 is again adhered and fixed by the cloth sticking roller 55 and is repeatedly printed by the printer unit. Thus, it is an apparatus for continuously recording a pattern or the like on the fabric 51.

  At this time, it is desirable that the printed fabric is wound while sufficiently drying. In particular, when printing on a long fabric of 20 to 100 m is continued for a long time, the printed fabric is discharged endlessly, so that the printed fabric overlaps the floor or the like and takes a place. If this is not taken up, the work is unsafe and there is a risk that it will get dirty unexpectedly. Therefore, it is necessary to perform a winding operation after printing. During this operation, a medium that is not related to printing such as paper, cloth, or vinyl may be sandwiched between the cloths to prevent show-through. Of course, it is not always necessary to wind up when cutting in the middle or short fabric.

  In the ink jet printer having the above-described configuration, in the present invention, the transport device includes an adhesive endless transport member provided with an adhesive layer formed by transferring an adhesive tape to an endless belt or a roller surface, The adhesive tape has no base material.

  In an ink jet printer, it is a common practice to increase the amount of ink shot in order to obtain a high density image. However, when the recording medium is a fabric, since the fabric is produced by knitting warp and weft, there is a space where no yarn is present, and when ink is ejected into this space, the back side of the fabric is present. A so-called back-through occurs that causes ink to escape.

  For this reason, a general textile inkjet printer is provided with a device for cleaning the endless transport member after using the endless transport member that receives the ink on the back of the fabric.

  In the case where an adhesive tape including a base material is used for such an endless conveying member, contamination of the adhesive surface can be solved by making the composition of the adhesive layer a silicone polymer, a fluorine-modified acrylic resin, or the like. However, the base material portion of the adhesive tape is exposed on the cross section of the adhesive layer as shown in FIG. 1 which is always generated during the pasting, and as described in FIG. The organic solvent and the colorant in the ink permeate into the base material portion, and the base material is deformed or contaminated.

  On the other hand, as shown in FIG. 2 b), by using an adhesive tape that does not include a base material and is formed of an adhesive layer alone, there is no base material that becomes a source of contamination or deformation in the cross-sectional portion, which is excellent. Durability can be obtained.

  Subsequently, the structure of the adhesive tape which does not contain the base material based on this invention is demonstrated.

  The adhesive tape which does not contain the base material which concerns on this invention is comprised in the state by which the adhesion layer 2 was pinched | interposed into a pair of peeling body 1, as shown in FIG.

  The material of the pressure-sensitive adhesive layer according to the present invention is characterized by using a silicone polymer, and examples of the silicone polymer include addition reaction curable silicone polymers and condensation polymerization curable silicone polymers.

  Crosslinking by addition reaction occurs between the component (A) and the component (B) of the crosslinking agent, and the gel fraction of the adhesive layer after curing is determined by the ratio of the crosslinking component.

  In this invention, it is preferable to mix | blend so that the molar ratio of the SiH group in (B) component with respect to the alkenyl group in (A) component may be in the range of 0.5-20, especially 0.8-15. If it is less than 0.5, the crosslinking density is lowered, and the holding force may be lowered accordingly. On the other hand, if it exceeds 20, the adhesive strength and tack may decrease, or the usable time of the treatment liquid may be shortened.

  In addition, in order to improve the heat resistance such as heat resistance and solvent resistance such as suppression of solvent penetration, the proportion of the cross-linking component in the composition may be increased. There may be effects such as reduced flexibility. From such points, the mass ratio (A: B) between the component (A) and the component (B) is preferably 20:80 to 80:20, and particularly 45:55 to 70:30. Is preferred. When the blending ratio of the component (A) is less than 20, adhesive properties such as adhesive strength and tack may be deteriorated, and when it exceeds 80, sufficient film strength cannot be obtained.

  Component (C) is an addition reaction control agent. When preparing a silicone adhesive layer coating solution and applying it to a substrate, the treatment solution should not thicken or gel before heat curing. It is to be added.

If it is less than 1 ppm, the curability is lowered, the crosslinking density is lowered, and the holding power may be lowered. If it exceeds 5,000 ppm, the usable time of the treatment bath may be shortened.

  The conductive fine particles of the component (E) may be added to the above-mentioned addition reaction curable silicone pressure-sensitive adhesive layer coating solution for the purpose of preventing electrification.

  Next, the release film or release paper, which is a release body to which an adhesive is applied and held, will be described.

  Here, the release film or the release paper is a base material for forming the adhesive layer, and at the same time, a base material for protecting the adhesive layer from foreign matters such as dust and dust when storing the adhesive. As a specific example of the release film, a film made of various resins such as polyethylene terephthalate, polybutylene terephthalate, polycarbonate, polyarylate is used as a base material, and a release treatment (silicone treatment) is performed on one or both sides of the base material with the adhesive layer. Etc.). Specific examples of the release film are the same as the release film except that the base material is paper.

  Specific examples of the coating solution for performing the release treatment for producing the release film and release paper are as follows. Among the DEHESIVE series manufactured by Asahi Kasei Wacker Silicone Co., Ltd., solvent-free 636, 919, 920, 921 924, emulsion type 929, 430, 440, 39005, 39006, solvent type 940, 942, 952, 953, 811, etc. are silicones for release paper manufactured by GE Toshiba Silicone Co., Ltd .: TPR6500, TPR6501, UV9300, UV9315 , XS56-A2775, XS56-A2982, TPR6600, TPR6605, TPR6604, TPR6705, TPR6722, TPR6721, TPR6702, XS56-B3884, XS56-A8012, XS56-B2654, TPR6700 , TPR6701, TPR6707, TPR6710, TPR6712, XS56-A3969, XS56-A3075, YSR3022, and the like.

  For the release film and release paper, a release treatment agent is generally selected in accordance with the desired pressure-sensitive adhesive, so there are not many common commercial products, but the release film and release paper that can be used in the present invention. Specific examples of the release film include an A50 liner manufactured by Teijin DuPont Films, Ltd., and a release paper manufactured by Yodogawa Paper Co., Ltd.

  The adhesive layer is coated on the release paper using a roll coater, blade coater, bar coater, air knife coater, gravure coater, reverse coater, die coater, lip coater, spray coater, comma coater, etc. The adhesive layer is formed through an electron beam exposure process such as drying, heating, and ultraviolet rays.

  Although the thickness of these adhesion layers is based also on the kind of adhesive, it is 3-100 micrometers normally, Preferably it is about 5-60 micrometers.

  Further, as an example of a general commercial product of a double-sided pressure-sensitive adhesive tape having no base material applicable to the present invention, manufactured by Adhesives Research: ARclear 8932, ARclad 7876, manufactured by Teraoka Seisakusho Co., Ltd. 7470 and the like.

  Next, a method of sticking the baseless adhesive tape to the endless transport member in a multilayer and creating the adhesive endless transport member will be described.

  First, for example, on the endless belt of the endless conveying member, the adhesive surface of the baseless adhesive tape from which the peeled body on one side is peeled off is attached. Next, the peeling body on the other surface is peeled off to expose the adhesive surface.

  Examples of the endless transport member that can be used in the present invention include a transport roller and an endless belt. In the present invention, the endless transport member is an endless belt, and the surface of the endless belt is coated with a fluororesin. One of them.

  The transport roller applicable to the present invention may have any shape as long as it can be rotated and transported, such as a cylindrical shape, an elliptical middle shape, and a polygonal shape, but the surface is covered with a fluororesin. It is preferable from the viewpoint of exerting the objective effect.

  Moreover, as an endless belt base material utilized for this invention, there exist what has become a film-like single film | membrane, and the thing which installed the core material in the film or the outer side. As a material for forming a film, the present invention is characterized in that a fluororesin is applied particularly from the viewpoint of preventing contamination with ink.

  Examples of the core material include metals and synthetic fibers, and examples of the synthetic fibers include glass fibers and aramid fibers. In the present invention, glass fiber is desirable from the viewpoints of substrate flexibility and durability, and it is desirable to coat with a fluororesin for the purpose of preventing friction with the transport roller during transport. The coating with the fluororesin is achieved by immersing the glass fiber belt in the fluororesin dispersion, pulling it up and heating it at 400 ° C. for 15 minutes to weld the fluororesin onto the glass fiber.

  As the fluororesin preferably used in the present invention, known fluororesins can be widely used. Specifically, PTFE (polytetrafluoroethylene), FEP (perfluoroethylene propene copolymer), PFA (perfluoroalkoxyalkane), ETFE (ethylene-ethylene), known under the name of Teflon (registered trademark) (Du Pont). Tetrafluoroethylene copolymer), ECTFE (ethylene-chlorotrifluoroethylene copolymer), FVDF (polyvinylidene fluoride), PCTFE (polychlorotrifluoroethylene), TFE / PDD (tetrafluoroethylene-perfluorodioxole copolymer) Etc. Among these, it is preferable to use PTFE.

  Next, a recording medium to which the ink jet printer of the present invention is applied, ink, and an ink jet textile printing process as a representative example will be described.

  The recording material used when printing an image with the ink jet printer of the present invention is not particularly limited, but it is preferable to use a fabric from the viewpoint that the effects of the present invention can be exhibited.

  Examples of fabric materials that can be preferably used in the present invention include cotton, hemp, wool, silk, rayon, cupra, polynosic, polyester, nylon, acrylic, vinylon, and blends thereof.

  In many cases, the fabric is usually prepared by appropriately selecting the type of yarn, the thickness of the yarn, the weaving method, the blending ratio, etc. so that the fabric texture desired by the fabric manufacturer can be obtained. There are no general products, but examples of test dyes from Kokusai Co., Ltd. are cotton, gold, broad, twill, satin, knit smooth, ponchiroma, flannel, canvas, etc., and hemp (ramie) broad, etc. However, for wool, muslin, tropical, surge, etc., for silk, feather double, seika palace, etc., for rayon, taffeta, sfumoslin, fuziette, etc., for cupra, taffeta, etc., for polynosic, broad etc. For lyocell, plain weave, etc., for diacetate, taffeta, etc., for polyester, taffeta, tropical, amundsen, spun yarn fabric, tetrex, georgette, crepe desin , Cocoons, jerseys, double piques, car seats, etc. for new synthetic fibers, such as Toraysee, Samia, etc., for cation dyeable polyester, knit smooth, etc. for nylon 6, taffeta, cocoons, jerseys, etc. Muslin, jersey, etc. for acrylic, Broad, etc. for vinylon, Polyester 65 / Cotton 35 broad, Polyester 65 / Cotton 35 twill, Polyester 50 / Cotton 50 knit smooth, Polyester 65 / Rayon 35 plain weave, etc. Examples of the polyurethane 20 / polyester 80 knit include AATCC Style 1, 10, SDC and the like for multi-fiber cloth.

  When applied to the ink jet printer of the present invention, the effect is remarkably exhibited particularly when a stretchable cloth such as a knit is precisely attached on the belt. Among them, it is effective when a fabric having a breaking elongation of 5% or more in both the longitudinal direction and the lateral direction is used. In general, fabrics that stretch well, such as those with a breaking elongation of 5% or more, are prone to wrinkling during the manufacture of the fabric, and are stretched and adhered well when applied precisely, creating gaps between the fibers and causing line-through. However, by applying a conveying member having an adhesive layer defined in the present invention, even a fabric having the above characteristics can be stably conveyed.

  Examples of the fabric having the above elongation include knit smooth for cotton, pontiloma, jersey for polyester, double picket, knitted smooth for cationic dyeable polyester, jersey for nylon 6, jersey for nylon 66, etc. For example, jersey or the like is used for acrylic, polyester 50/50 cotton knit smooth is used for blend, and polyurethane 20 / polyester 80 is used for knitting.

  The reason why the ink jet printer of the present invention is suitably used for the above-mentioned stretched fabric is considered as follows.

  In inkjet image recording, the amount of ink applied directly affects the image density. Therefore, in order to obtain a high-quality and high-quality printed matter, it is necessary to increase the amount of ink applied. However, when ink is applied onto a fabric that does not stretch, the speed of the ink that penetrates into the fabric is given to the ink. The ink droplets do not catch up with the speed and the ink droplets coalesce, and the image is blurred. In addition, when a fine line is drawn, there is a problem that an image blur along a fiber called feathering occurs and a desired fine line cannot be obtained. For this reason, until now, bleeding has been inevitable with high-density prints.

  However, in the present invention, it is possible to increase the ink absorption speed and greatly reduce the bleeding by stretching the fabric having a breaking elongation of 5% or more in advance to stretch the fabric (space portion). did it. As a result, it was possible to obtain a printed matter with a higher density and higher quality than before.

  In the case of the inkjet printing method according to the present invention, in order to obtain a uniform dyed product, natural impurities (oils, waxes, pectic substances, natural pigments) attached to the fabric fibers before the water-soluble polymers are pretreated on the fabric. Etc.), it is desirable to wash away the residues of the chemicals used in the fabric manufacturing process (such as glue) and dirt. As cleaning agents used for cleaning, alkaline agents such as sodium hydroxide and sodium carbonate, surfactants such as anionic surfactants and nonionic surfactants, enzymes and the like are used.

  In the inkjet textile printing method according to the present invention, a pretreatment liquid is applied to a fabric by an inkjet method (pretreatment step), and then on a fabric containing fibers that can be dyed with a disperse dye or a pigment. After forming an image by ink jet method using ink (ink application process), the fabric to which ink is applied is heat-treated (coloring process), and the heat-treated fabric is further washed (washing process). Printing is completed and a printed product is obtained.

  In the pretreatment step according to the present invention, for the purpose of imparting a bleeding prevention effect, it is preferable to impart a pretreatment agent by a pad method, a coating method, a spray method or the like.

  The pretreatment method is not particularly limited as long as a method suitable for the fiber material and the ink is appropriately selected from known methods such as pretreatment of water-soluble polymers on the cloth. For example, it is used for a fabric provided with 0.2 to 50% by mass of at least one substance selected from the group consisting of water-soluble metal salts, polycation compounds, water-soluble polymers, surfactants and water repellents. Therefore, it is possible to prevent a high degree of bleeding, and a high-definition image can be printed on the fabric, which is preferable.

  The example of the specific water-soluble polymer used as a pretreatment agent is given. Examples of natural water-soluble polymers include starches such as corn and wheat, cellulose derivatives such as carboxymethylcellulose, methylcellulose and hydroxyethylcellulose, sodium alginate, guar gum, tamarind gum, locust bean gum, gum arabic and other polysaccharides, gelatin, Examples of protein substances such as casein and keratin, and synthetic water-soluble polymers include polyvinyl alcohol, polyvinyl pyrrolidone, and acrylic acid polymers. As the surfactant, for example, anionic, cationic, amphoteric and nonionic surfactants are used. Typically, anionic surfactants include higher alcohol sulfates and sulfonates of naphthalene derivatives. Quaternary ammonium salts, etc .; amphoteric surfactants, imidazoline derivatives, etc .; nonionic surfactants, polyoxyethylene alkyl ethers, polyoxyethylene propylene block polymers, etc. Sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester, ethylene oxide adduct of acetylene alcohol, and the like. Examples of the water repellent include silicon, fluorine-based and wax-based ones. These water-soluble polymers and surfactants that are pre-applied to the fabric are stable against high-temperature environments because they do not cause dirt due to taring when ink-jet printing and color development at high temperatures. Preferably there is. Further, these water-soluble polymers and surfactants that are previously imparted to the fabric are preferably those that can be easily removed from the fabric by washing after ink jet printing and color development at high temperature.

  Moreover, it is preferable that the dyeing adjuvant is contained in the inkjet ink for textile printing used when dyeing | staining by the high temperature steaming method mentioned later, or the fabric used for textile printing.

  The dyeing assistant has the effect of reducing the amount of moisture that is re-evaporated and shortening the temperature rising time by making a eutectic mixture with water condensed in the form of cloth when steaming the printed fabric. Further, this eutectic mixture has the effect of dissolving the dye on the fiber and promoting the diffusion rate of the dye into the fiber. Urea is mentioned as a dyeing assistant. This dyeing assistant may be applied to the fabric in advance or may be contained in the pretreatment liquid.

  In the pretreatment liquid, the dissolved gas contained in the liquid is a factor that impairs the resolution and clarity of the printed matter and causes generation of fine bubbles. Methods for degassing a dissolved gas from a liquid can be broadly divided into a method of degassing by a physical method such as boiling or reduced pressure, and a chemical method of mixing an absorbent into the liquid. In the present invention, degassing can be performed by any means. In particular, the method of permeating and removing the dissolved gas in the liquid by passing the liquid through the gas-permeable hollow fiber membrane and reducing the pressure on the outer surface side of the hollow fiber membrane has an adverse effect on the physical properties of the liquid. The dissolved gas in the liquid can be efficiently removed without giving, which is preferable.

  Next, the ink used in the ink jet textile printing method according to the present invention will be described.

  The ink in the present invention contains at least a coloring material, a water-soluble organic solvent, and water. Examples of the color material include disperse dyes, reactive dyes, acid dyes, direct dyes, pigments, and oil-soluble dyes, among which disperse dyes are preferably used.

  Specific compounds of the coloring material that are preferably used in the present invention are shown below, but the present invention is not limited to these exemplified compounds.

  In the present invention, the content of the color material contained in the ink is preferably 0.1 to 20% by mass, and more preferably 0.2 to 13% by mass.

  Examples of the water-soluble organic solvent used in the ink according to the present invention include the same water-soluble organic solvents that can be used for the pretreatment liquid. The amount of the water-soluble organic solvent is preferably 10 to 60% by mass with respect to the total ink mass.

  Examples of the surfactant used in the ink according to the present invention include the same surfactants that can be used in the pretreatment liquid.

  When these surfactants are used, they can be used singly or as a mixture of two or more, and by adding in a range of 0.001 to 1.0% by mass with respect to the total mass of the ink, The surface tension can be arbitrarily adjusted, which is preferable.

  In the ink according to the present invention, an inorganic salt can be added to the ink in order to keep the ink viscosity and the dye stable and improve the color development. Examples of the inorganic salt include sodium chloride, sodium sulfate, magnesium chloride, magnesium sulfate and the like. When implementing this invention, it is not limited to these.

  In the ink according to the present invention, an antiseptic and an antifungal agent can be added to the ink in order to maintain long-term storage stability of the ink. Examples of the antiseptic and antifungal agent include aromatic halogen compounds (for example, Preventol CMK), methylene dithiocyanate, halogen-containing nitrogen sulfur compounds, 1,2-benzisothiazolin-3-one (for example, PROXEL GXL), and the like. Is mentioned.

  The fabric to which the ink has been applied is then subjected to a treatment in the color development step.

  The color development step is a step of developing the original hue of ink by adhering to and fixing the dye in the ink that has only adhered to the fabric surface after printing and is not sufficiently adsorbed and fixed to the fabric. As the method, steaming by steam, baking by dry heat, thermosol, HT steamer by superheated steam, HP steamer by pressurized steam, etc. are used. They are appropriately selected depending on the material to be printed, ink, and the like. Further, the printed fabric may be immediately heat-treated or may be heat-treated after a while and may be dried and colored according to the intended use, and any method may be used in the present invention.

  In the ink jet textile printing method of the present invention, when dyeing with a disperse dye, not only a method of developing a color at a high temperature but also a carrier may be used. The compound used as the carrier is preferably a compound having characteristics such as large dyeing acceleration, simple use, stable, low burden on human body and environment, easy removal from the fiber, and no influence on dye fastness. Examples of carriers include o-phenylphenol, p-phenylphenol, methylnaphthalene, alkyl benzoate, alkyl salicylate, phenols such as chlorobenzene and diphenyl, ethers, organic acids, hydrocarbons and the like. These promote the swelling and plasticization of difficult-to-dye fibers that are difficult to dye at temperatures around 100 ° C. like polyester, and make it easier for disperse dyes to enter the fibers. The carrier may be preliminarily adsorbed on the fibers of the fabric used for inkjet printing, or may be included in the inkjet ink.

  After the heat treatment, a cleaning process is necessary. This is because a dye that has not participated in the dyeing remains, resulting in poor color stability and low fastness. It is also necessary to remove the pretreatment product applied to the fabric. If left as it is, not only the fastness is lowered, but also the fabric is discolored. Therefore, cleaning according to the object to be removed and the purpose is essential. The method is selected according to the material and ink to be printed. For example, in the case of polyester, treatment is generally performed with a mixed solution of caustic soda, a surfactant, and hydrosulfite. The method is usually carried out in a continuous type such as an open soaper or in a batch type using a liquid dyeing machine, and any method may be used in the present invention.

  After washing, drying is necessary. After the washed fabric is squeezed or dehydrated, it is dried or dried using a dryer, heat roll, iron or the like.

  EXAMPLES Hereinafter, the present invention will be specifically described with reference to examples, but the present invention is not limited thereto. In addition, although the display of "part" or "%" is used in an Example, unless otherwise indicated, "part by mass" or "mass%" is represented.
