Definitions
- the present invention relates to an inkjet recording method and an inkjet recording apparatus.
- ink is ejected from an inkjet head to a recording medium, and droplets of the ink are collected to thereby form an image.
- the inkjet recording method is also utilized for textile printing.
- the textile printing as the ink, an ink containing an aqueous medium and a colorant is usually used.
- the recording medium is usually a cloth.
- a cloth subjected to a pretreatment with a pretreatment agent for suppression of ink blur is used for the cloth.
- the cloth pretreated with a pretreatment agent is usually dried and then used, and therefore has the property of absorbing the aqueous medium of the ink.
- a one-pass inkjet recording method is known as a commercially advantageous inkjet recording method.
- the one-pass inkjet recording method at least one ink is ejected from an inkjet head onto the surface of a recording medium by one scanning of the inkjet head over the recording medium to thereby form an image.
- inks of a plurality of colors are superposed on the recording medium having absorbability, such as a cloth, by the one-pass inkjet recording method, edging of the color of an ink ejected later may be formed on an image formed, causing the image to be lack in definition.
- US 5 348 557 A discloses a process for dyeing sheetlike fiber materials, in particular those made of or containing cellulose fibers, with anionic dyes, in particular those having fiber-reactive groups, which comprises applying an alkali-free and preferably low-electrolyte or completely electrolyte-free aqueous solution of the anionic dye by the inkjet printing spray technique to a fiber material which has been pretreated and modified with a compound that contains one or more primary, secondary or tertiary amino groups or quaternary ammonium groups, which amino/ammonium groups may be part of a heterocycle.
- WO 2014/010710 A1 discloses an image forming method, including: a pre-treatment liquid application step for applying a pre-treatment liquid on a recording medium including a substrate and a coating layer at least on one surface of the substrate, wherein the pre-treatment liquid is applied on a surface of the recording layer with the coating layer; a drying step for drying the recording medium on which the pre-treatment liquid has been applied; and an image forming step for forming an image on the recording medium after drying by discharging a water-based ink by inkjet method, wherein the pre-treatment liquid includes a water-soluble cationic polymer, an ammonium salt of an organic acid and water, and wherein the water-based ink includes water and negatively charged colored particles including a colorant.
- US 2014/036014 A1 discloses inkjet ink compositions for forming an image in a form of an elastic film attached to a surface of a stretchable and/or flexible substrate and processes utilizing same for inkjet printing color images on various substrates such as colored and absorptive or impregnable stretchable materials, which are characterized by heightened efficiency in process time, ink and energy consumption, as well as products having durable, wash-fast and abrasion-fast images printed thereon by the process.
- the ink compositions comprise a first part, which contains a property-adjusting agent and a carrier, and a second part which contains an emulsified property-sensitive proto-elastomeric film-forming agent, a colorant and a carrier, such that the second part congeals upon contact with the property-adjusting agent.
- the second part is digitally applied to the substrate less than 1 second following the application of the first part to the substrate.
- An object of the present invention is to form a definite image even in the case of forming of an image on a recording medium having absorbability by a one-pass inkjet recording method.
- the surface of the recording medium is wetted, before ink arrival at the surface of the recording medium, to the same degree of wetting as in landing of ink droplets, and therefore ink droplets first landed on the recording medium and ink droplets landed thereon later are spread on the recording medium in the substantially same manner. Accordingly, no edging of the color of an ink ejected later occurs around an image formed, and therefore a definite image can be formed in the case of forming of an image on a recording medium having absorbability by a one-pass inkjet recording method.
- An inkjet recording method is a so-called one-pass inkjet recording method including ejecting two or more inks to the surface of a recording medium by one scanning of an inkjet head over the recording medium to thereby form an image.
- the inks each contain an aqueous medium and a colorant.
- the inks are two or more inks and are usually inks of different colors, but may be inks of the same color.
- the inks may be any number of inks as long as the number of inks is two or more and a predetermined appearance is obtained by superposing.
- the aqueous medium is a liquid containing water as a main component and is water or an aqueous solution.
- examples of the solute of the aqueous medium include a salt and a water-soluble organic solvent.
- the content of the water-soluble organic solvent in each of the inks is preferably 15 to 70mass%, more preferably 30 to 60mass% from the viewpoints of dissolution of various components in each of the inks and drying property of the inks.
- the content is preferably 15mass% or more from the viewpoints that liquid properties such as ink viscosity are adjusted and a surfactant is dissolved. If the content is more than 70mass%, the inks may be deteriorated in drying property to cause a cloth after printing not to be dried, making it impossible to superpose or roll up printed products before a heat treatment (color development).
- water-soluble organic solvent examples include a polyhydric alcohol, an amine, a monohydric alcohol, an alkyl ether of a polyhydric alcohol, 2,2'-thiodiethanol, an amide, a heterocyclic compound, and acetonitrile.
- polyhydric alcohol examples include 1,6-hexanediol, 1,2-hexanediol, 1,5-pentanediol, 1,2-pentanediol, 2,2-dimethyl-1,3-propanediol, 2-methyl-2,4-pentanediol, 3-methyl-1,5-pentanediol, 3-methyl-1,3-butanediol, 2-methyl-1,3-propanediol and glycols.
- glycols examples include ethylene glycol, glycerin, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, tetraethylene glycol, triethylene glycol, tripropylene glycol, 1,2,4-butanetriol, diethylene glycol, propylene glycol, dipropylene glycol and butylene glycol.
- the content of the glycols in each of the inks is preferably 15 to 60mass%, more preferably 30 to 60mass% not only from the viewpoint of the above reasons, but also from the viewpoint that a water-soluble polymer of the cloth is inhibited from being excessively swollen, to allow an ink to be ejected later to easily penetrate into the cloth, resulting in forming of a higher-definition image.
- Examples of the amine include ethanolamine and 2-(dimethylamino)ethanol.
- Examples of the monohydric alcohol include methanol, ethanol and butanol.

- the relative humidity of the humidified air is 50 to 80%, more preferably 55 to 75% from such viewpoints.
- the temperature of the humidified air may be so low to thereby cause the humidity of the humidified air to be insufficient, resulting in insufficient reproduction of wetting of the surface of the recording medium by landing of ink droplets, and may be so high to thereby cause drying of the surface of the recording medium properly wetted to be promoted, also resulting in insufficient reproduction of wetting of the surface of the recording medium by landing of ink droplets.
- the temperature of the humidified air is preferably 20 to 40°C, more preferably 20 to 30°C from such viewpoints.
- the volume of the humidified air may be so small to thereby cause wetting of the surface of the recording medium by landing of ink droplets to be insufficiently reproduced, and may be so large to thereby cause the shape of the surface of the recording medium and ink landing to be disordered, or cause the recording medium to be excessively wetted to promote penetration of the inks into the recording medium, resulting in an insufficient image density on the surface of the recording medium.

- Blowout port 112 is disposed upstream of inkjet heads 111 in X direction, and expanded to a region in which blowout port 112 is at least overlapped with all inkjet heads 111 in Y direction.
- Each inkjet head 111 includes, for example, an ink chamber, a pressure chamber and a nozzle (not illustrated), and is connected to an ink tank that accommodates ink of each color.

- FIG. 3A schematically illustrates a mode where a first ink penetrates into a cloth
- FIG. 3B schematically illustrates a mode where, when a second ink is further ejected to a cloth which is humidified immediately before ejection of the first ink and to which the first ink is ejected, the second ink penetrates into the cloth
- FIG. 3C schematically illustrates a mode where, when a second ink is further ejected to a cloth which is not humidified before ejection of the first ink and to which the first ink is ejected, the second ink penetrates into the cloth.
- ink for example, cyan ink
- the ink penetrates into the cloth around positions where ink droplets are landed, with being spread in both of the direction along the surface of the cloth and the depth direction, as illustrated in FIG. 3A .
- the cloth is here dry, the ink penetrates into the cloth, with being absorbed to a water-soluble polymer attached to a fiber, in the pretreatment agent.
- the cloth is wet, the ink penetrates into the cloth in which the water-soluble polymer is swollen, and therefore the ink less penetrates in the thickness direction of the cloth and is more easily spread in the direction along the surface than the ink in the case where the cloth is dry.
- the cyan ink When the cloth is wetted in advance, in ejection of the cyan ink, to the same degree as the degree of wetting by landing of droplets of the ink, the cyan ink is spread in the same manner as the spreading in a cloth after ink ejection, and thus penetrates into the above cloth.
- the yellow ink penetrates into the cloth in the same manner as the cyan ink, as illustrated in FIG. 3B .
- the reason for this is considered because the state of the cloth portion in penetration of the cyan ink (for example, the degree of swelling of the water-soluble polymer) is substantially the same as the state of the cloth portion in penetration of the yellow ink.
- the yellow ink penetrates into a portion that is substantially the same as the cloth portion into which the cyan ink penetrates, to thereby form a green dot.
- the yellow ink penetrates into a wider portion than the portion into which the cyan ink penetrates, in the direction along the surface of the cloth, namely, the outside of the green dot, as illustrated in FIG. 3C . Therefore, edging of the yellow ink ejected later is formed on an image formed on the surface of the cloth (arrow in FIG. 3C ).
- both of the cyan ink and the yellow ink penetrate into the cloth in a wider region from the landing positions.
- the volume of ink droplets is limited, and therefore the inks may further penetrate in the direction along the surface of the cloth and in the thickness direction to thereby decrease the hues of the inks, resulting in no sufficient development on the surface of the cloth.
- the inks may be thus excessively spread to cause the boundary between different hues in an image to be formed on the surface of the cloth to be more blurred, thereby resulting in a further reduction in definition of the image.
- the inkjet head is moved from side to side (for example, in Y direction in FIG. 2A ) as compared with that in a scanning inkjet recording apparatus in which an inkjet head ejects ink with several times of scanning, and the amount of ink ejection per unit time is generally smaller than that in a one-pass inkjet recording apparatus. Therefore, ink is easily dried to easily stabilize the humidity on the recording medium in image forming by the scanning inkjet recording apparatus, as compared with image forming by the one-pass inkjet recording apparatus. Accordingly, the environment around the recording medium is not significantly changed between first droplet ejection and second droplet ejection, and the degrees of spreading of the inks landed on the recording medium are not substantially affected
- an image is usually formed in an interleaved manner in the scanning inkjet recording apparatus. Therefore, for example, a case where the cyan ink is landed at a position where the yellow ink is landed and a case where the yellow ink is landed at a position where the cyan ink is landed are generated randomly and at the same degree in the entire recording medium (cloth). Accordingly, even if the dot diameters of the yellow ink and the cyan ink landed at the same position are different, portions different in the landing order are present randomly, but almost uniformly in an area of the recording medium, in which an image is formed, to thereby form an image small in a feeling of strangeness as a whole.
- the inkjet head is not moved in image forming by the one-pass inkjet recording apparatus, and the amount of ink ejection per unit time is generally larger than that in the scanning inkjet recording apparatus. Therefore, the humidity near the inkjet head tends to become higher. Accordingly, the environment around the recording medium significantly differs between first droplet ejection and second droplet ejection, also resulting in the difference in the degree of spreading between the inks landed on the recording medium.
- the inkjet head is secured and the ink ejection order is usually fixed in the one-pass inkjet recording apparatus (e.g., the yellow ink is first ejected, and the cyan ink is then ejected). Therefore, even a slight difference is generated between the dot diameter of the yellow ink and the dot diameter of the cyan ink to thereby cause a feeling of strangeness due to the difference to be increased in the entire image formed, resulting in forming of an image large in a feeling of strangeness.
- the inkjet recording method is an inkjet recording method including ejecting two or more inks, each containing an aqueous medium and a colorant to the surface of a recording medium having absorbability of the aqueous medium, by one scanning of an inkjet head over the recording medium, to thereby form an image, wherein the recording medium is a cloth or a non-woven fabric, and the inkjet recording method includes humidifying the surface of the recording medium before ejection of the inks to the recording medium. Therefore, a definite image can be formed even in the case of forming of an image on a recording medium having absorbability by a one-pass inkjet recording method.
- the method inkjet recording method, it is much more effective from the viewpoint of forming of a high-definition image on the cloth at high productivity that the method can be applied to textile printing and the recording medium includes, on the surface thereof, a pretreatment agent that prevents blur of the inks.
- the inks each contain glycols and the content of the glycols in each of the inks is 15 to 60mass%. It is much more effective from the above viewpoints that the content of the glycols in each of the inks is 30 to 60mass%.
- the inkjet recording apparatus is a one-pass inkjet recording apparatus including an inkjet head that ejects ink being relatively moved in one direction to a recording medium, to form a predetermined image by one scanning to the recording medium, and a conveyance mechanism that holds the recording medium to relatively move the inkjet head in one direction to the recording medium, wherein the recording medium is a cloth or a non-woven fabric, and the inkjet recording apparatus further includes a humidification apparatus that humidifies the front portion of the surface of the recording medium in the scanning direction of the inkjet head, of the recording medium. Therefore, a definite image can be formed even in the case of forming of an image on a recording medium having absorbability by a one-pass inkjet recording method.
- the inkjet head includes a plurality of nozzle groups that eject inks of a plurality of colors, each of the nozzle groups ejects ink of a different color, and a plurality of the humidification apparatuses are disposed corresponding to the respective nozzle groups and are disposed in front in the scanning direction of the nozzle groups.
- the inkjet recording apparatus here includes a humidification apparatus for each inkjet head, it may include a humidification apparatus for each inkjet head unit.
- the inkjet recording apparatus includes inkjet head units 41, and blowout ports 412 for individual inkjet head units 41, the ports disposed upstream in the movement direction of the cloth (opposite in the case of X direction), as illustrated in FIG. 4 .
- Inkjet head units 41 are the same as inkjet head units 11 except for having no blowout port 112, and blowout ports 412 are each the same as blowout port 112 except for being disposed outside of the inkjet head units.
- the inkjet recording apparatus illustrated in FIG. 4 is preferable because of exerting the same effect as that in the inkjet recording apparatus illustrated in FIG. 1 and also being more easily altered so that the existing inkjet recording apparatus for textile printing can be applied to the present invention.
- the inkjet recording apparatus may include one humidification apparatus to be disposed upstream of a plurality of inkjet heads.
- the humidification apparatus in the inkjet recording apparatus may be one other than the blowout port, for example, a spray apparatus that feeds mist to the cloth.
- the cloth in the inkjet recording apparatus, while the cloth is moved relative to the inkjet head in X direction, it may be moved relative to the inkjet head in the direction opposite to X direction. In such a case, the cloth may be secured or may be moved in synchronization with movement of the inkjet head in X direction or the opposite direction thereto.
- DISPERBYK-190 produced by BYK, comb-like block polymer dispersant, solid content: 40mass%
- a dispersant was added to 60 parts by weight of ion exchange water, and 5 parts by weight of dipropylene glycol propyl ether was mixed therewith.
- C.I. Disperse Blue-60 as a disperse dye was added to the solution and pre-mixed, the resultant was dispersed by a sand grinder filled with 0.5-mm zirconia beads at a volume fraction of 50%, to provide dye dispersion liquid A-1 having a dye solid content of 20mass%.
- the Z average particle size of a disperse particle of dye dispersion liquid A-1 obtained was measured by a dynamic light scattering particle size distribution meter Zeta Sizer Nano S (manufactured by Malvern Instruments Ltd.), and was 0.15 ⁇ m.
- dye dispersion liquid A-1 Twenty five parts by weight of dye dispersion liquid A-1 was added to a mixed liquid in which 40 parts by weight of ethylene glycol, 7 parts by weight of glycerin, 0.2 parts by weight of PROXEL GXL (antifungal agent produced by LONZA Japan) and 0.2 parts by weight of KF-351A (surfactant produced by Shin-Etsu Chemical Co., Ltd.) were added to 27.6 parts by weight of ion exchange water, and the resultant was stirred and thereafter filtered by a filter of 1 ⁇ m to provide cyan ink 1.
- a mixed liquid 40 parts by weight of ethylene glycol, 7 parts by weight of glycerin, 0.2 parts by weight of PROXEL GXL (antifungal agent produced by LONZA Japan) and 0.2 parts by weight of KF-351A (surfactant produced by Shin-Etsu Chemical Co., Ltd.) were added to 27.6 parts by weight of ion exchange water, and the resultant was stirred and
- cyan ink 2 was obtained in the same manner as production of cyan ink 1 except that the amount of ion exchange water to be added and the amount of ethylene glycol to be added were changed to 57.6 parts by weight and 10 parts by weight, respectively.
- Dye dispersion liquid A-2 was obtained in the same manner as production of dye dispersion liquid A-1 except that the disperse dye was changed to C.I. Disperse Yellow-114.
- the Z average particle size of a disperse particle of dye dispersion liquid A-2 obtained was 0.17 ⁇ m.
- Yellow ink 1 was obtained in the same manner as in production of the cyan ink except that dye dispersion liquid A-1 was changed to dye dispersion liquid A-2.
- yellow ink 2 was obtained in the same manner as in production of yellow ink 1 except that the amount of ion exchange water to be added and the amount of ethylene glycol to be added were changed to 57.6 parts by weight and 10 parts by weight, respectively.
- a polyester cloth in which the fineness of a thread was 50 d was immersed in an aqueous carboxymethyl cellulose solution as a pretreatment, and squeezed and dried.
- Blowout ports for feeding humidified air were disposed upstream, in the feeding direction of the cloth, of inkjet heads of respective colors of a commercially available inkjet recording apparatus for one-pass textile printing so as to be overlapped with the inkjet heads in the width direction of the cloth, to prepare a one-pass tester illustrated in FIG. 1 .
- a fine line (cyan: 75%, yellow: 75%) of 0.5 mm in width was printed on the cloth by use of cyan ink 1 and yellow ink 1 described above together with the tester, preliminarily dried, thereafter subjected to HT steam treatment at 175°C for 10 minutes, thereafter washed with water, subjected to reduction washing with an aqueous 0.2% hydrosulfite solution at 80°C, and furthermore thereafter sufficiently washed with water and dried.
- the color blur of the fine line to be formed was observed visually and by an optical microscope at 100-fold magnification, and evaluated according to the following criteria.
- the "color blur” means the difference in blur between cyan and yellow colors.
- a fine line and a rectangular image were formed on the cloth in the same manner as in Example 1 except that no humidification of the cloth before ink ejection was performed, and the fine line and the image were evaluated.
- the rectangular image in Comparative Example 1 was a reference image in the sensory test of the image density.
- a fine line and a rectangular image were formed on the cloth in the same manner as in Example 1 except that a liquid composition (penetrant) was attached to the cloth as described in PTL 1 instead of humidification of the cloth before ink ejection, and the fine line and the image were evaluated.
- a liquid composition penetrant
- Blowout ports for feeding humidified air were disposed at the tips (namely, both ends of each inkjet head), in the scanning direction (direction across the feeding direction of the cloth), of inkjet heads of respective colors of a commercially available inkjet recording apparatus for scanning textile printing so as to be overlapped with the inkjet heads in the scanning direction, to prepare a scanning comparative tester.
- the "scanning” means an inkjet recording method in which ink is ejected to a cloth with the cloth being conveyed and an inkjet head being reciprocated in the direction across the conveyance direction of the cloth.
- a fine line and a rectangular image were formed on the cloth in the same manner as in Example 1 except that the comparative tester was used, and the fine line and the image were evaluated.
- a fine line and a rectangular image were formed on the cloth in the same manner as in Comparative Example 3 except that no humidification of the cloth before ink ejection was performed, and the fine line and the image were evaluated.
- Example 1 The evaluation results in Example 1 and Comparative Examples 1 to 4 are shown in Table 1.
- Table 1 Recording system Humidification Color blur Image density Example 1 One-pass Humidified air A A Example 2 One-pass Humidified air B A Comparative Example 1 One-pass None C A Comparative Example 2 One-pass Penetrant A C Comparative Example 3 Scanning Humidified air A A Comparative Example 4 Scanning None A A
- Example 2 color blur was more suppressed in Example 1 as compared with Example 2. From the foregoing, the concentration of glycols in each ink is more effectively 15mass% or more from the viewpoint of suppression of color blur.
- the present invention can allow a high-definition image to be formed even on a recording medium having absorbability of an aqueous medium by a one-pass system high in productivity. Accordingly, the present invention is expected to contribute to further development of high-speed and high-definition inkjet textile printing.
