Title: Colored dispersion, recording medium, and textile printing method for hydrophobic fibers

Description:
TECHNICAL FIELD 
     The present invention relates to a colored dispersion liquid, a recording medium to which the colored dispersion liquid is adhered, and a method for textile printing of a hydrophobic fiber using the colored dispersion liquid. 
     BACKGROUND ART 
     In recent years, there has been proposed a recording method for performing plate-less printing by inkjet, and textile printing by inkjet printing (inkjet textile printing) has also been performed in the printing of fibers including cloth, etc. Textile printing by inkjet printing has various advantages such as plate-free, resource saving, energy saving, and easy high-definition expression, compared to conventional textile printing methods such as screen printing, etc. 
     Here, hydrophobic fibers typified by polyester fibers are generally dyed by a water-insoluble coloring material. For this reason, as an aqueous ink for printing of hydrophobic fibers by inkjet printing, it is generally necessary to use dispersed inks, in which a water-insoluble coloring matter is dispersed in water, and which have good performance such as dispersion stability. 
     Inkjet textile printing methods for hydrophobic fibers are roughly divided into direct printing and sublimation transfer methods. The direct printing method is a textile printing method in which ink is directly applied (printed) to a hydrophobic fiber, and then a dye in the ink is heat treated by high temperature steaming or the like, so that the dye is dyed and fixed to the hydrophobic fiber. On the other hand, the sublimation transfer method is a textile printing method in which ink is applied (printed) to an intermediate recording medium (a special transfer paper, etc.), then an ink application surface of the intermediate recording medium and a hydrophobic fiber are superimposed on each other, and then a dye is transferred by heat from the intermediate recording medium to the hydrophobic fiber. 
     The sublimation transfer method is mainly used for printing of banner flags, etc. and easily sublimating dyes which are excellent in transferability to hydrophobic fibers by heat treatment are used in the ink. The processing steps include the two steps of (1) a printing step: a step of applying a dye ink to an intermediate recording medium by an inkjet printer; and (2) a transfer step: a step of transferring and dyeing the dye from the intermediate recording medium to the fiber by heat treatment. Since commercially available transfer papers can be widely used, pretreatment of fibers is not required, and a washing step is also omitted. 
     As an ink for use in the sublimation transfer method, an aqueous ink in which a water-insoluble dye is dispersed in water has been generally used. For example, Patent Document 1 describes that an aqueous ink is prepared by adding a water-soluble organic solvent as a moisturizing agent (drying inhibitor), a surfactant as a surface tension adjusting agent, and other additives (a pH adjuster, a preservative antifungal agent, a defoaming agent, and the like) to a dye dispersion liquid obtained by dispersing a water-insoluble dye selected from a disperse dye and an oil-soluble dye in water using a dispersant, to optimize physical characteristics (physical properties) such as particle size, viscosity, surface tension, pH, etc.

     DISCLOSURE OF THE INVENTION 
     Problems to be Solved by the Invention 
     However, when the present inventors have studied a conventional aqueous ink in which a water-insoluble dye is dispersed in water, it has been found that, even when the dispersion stability of the dye dispersion is relatively good, when a component such as a surfactant is added to the dye dispersion to prepare an aqueous ink, the particles in the aqueous ink aggregate and the dispersion stability decreases.

     [Process for Preparing Colored Dispersion Liquid, etc.] 
     As a method for preparing the colored dispersion liquid according to the present embodiment, for example, a method of preparing an aqueous dispersion liquid containing the (A) C.I. Disperse Orange 25, the (B) coloring matter, and a dispersant and further adding an additive such as a water-soluble organic solvent, as required, may be mentioned. 
     Examples of the method of preparing an aqueous dispersion include a known method such as stirring and mixing each component constituting the aqueous dispersion using a sand mill (bead mill), a roll mill, a ball mill, a paint shaker, an ultrasonic disperser, a high-pressure emulsifier, or the like. For example, when a sand mill is used, first, each component and beads as a dispersion medium are charged into a sand mill. As the beads, glass beads having a particle diameter of 0.01 to 1 mm, zirconia beads, or the like can be used. The amount of the beads to be used is preferably 2 to 6 parts by mass per 1 part by mass of the dispersion target. Then, the sand mill is operated to perform a dispersion treatment. Dispersion treatment conditions are generally preferably 1 to 20 hours at 1,000 to 2,000 rpm. Then, the beads are removed by filtration or the like after the dispersion treatment, thereby obtaining an aqueous dispersion. 
     The thus-prepared colored dispersion liquid may be subjected to microfiltration using a membrane filter or the like. In particular, when the colored dispersion liquid is used as an ink for inkjet textile printing, it is preferable to perform microfiltration for the purpose of preventing clogging or the like of the nozzle. The pore size of the filter used for microfiltration is typically 0.1 to 1 μm, and preferably 0.1 to 0.8 μm. 
     In addition, the viscosity at 25° C. of the colored dispersion liquid as described in the present embodiment is preferably about 3 to 20 mPa·s when measured by an E-type viscometer from the viewpoint of discharge responsiveness at high speed. Further, the surface tension at 25° C. of the colored dispersion liquid as described in the present embodiment is about 20 to 45 mN/m when measured by a plate method. Actually, the surface tension at 25° C. is adjusted to obtain an appropriate physical property value in consideration of the discharge amount, response speed, ink droplet flight characteristics, etc. of the inkjet printer to be used. 
     The colored dispersion liquid as described in the present embodiment can be used in various fields, and is suitable for a waterborne writing ink, a waterborne printing ink, an information recording ink, textile printing, and the like. The colored dispersion liquid as described in the present embodiment is particularly preferably used as an ink for inkjet textile printing. 
     According to the colored dispersion liquid as described in the present embodiment, it is possible to effectively suppress particles in the colored dispersion liquid from aggregating during storage and increasing in average particle diameter, and also to effectively suppress particles from settling during storage. In other words, according to colored dispersion liquid of the present embodiment, it is possible to stably maintain a dispersed state of particles in the colored dispersion liquid. 
     In addition, the colored dispersion liquid as described in the present embodiment has a good initial filling property to an inkjet printer head and good continuous printing stability. Further, it is possible to obtain a clear image without bleeding of the image on paper after printing. 
     &lt;Recording Medium&gt; 
     The recording medium as described in the present embodiment is a recording medium to which the colored dispersion liquid as described in the present embodiment is adhered. The recording medium is not particularly limited as long as the recording medium is recordable with the colored dispersion liquid as described in the preset embodiment, and a fiber, paper (normal paper, inkjet exclusive paper, etc.) can be mentioned. In particular, the recording medium as described in the present embodiment is preferably a hydrophobic fiber to which the colored dispersion liquid as described in the present embodiment is attached. 
     Examples of the hydrophobic fiber include polyester fibers, nylon fibers, triacetate fibers, diacetate fibers, polyamide fibers, and mixed spun fibers, etc. using two or more types of these fibers. Mixed spun fibers of these hydrophobic fibers with regenerated fibers such as rayon or natural fibers such as cotton, silk, wool, etc. are also included in the hydrophobic fibers in this specification. Among the fibers, those having an ink-receiving layer (anti-bleeding layer) are also known, and such fibers are also included in the hydrophobic fibers. A method for forming the ink-receiving layer is known technology and the fiber having an ink-receiving layer can also be obtained as a commercially available product. The material, structure, and the like of the ink-receiving layer are not particularly limited, and may be used as appropriate depending upon the purpose and the like. 
     &lt;Method for Textile Printing of Hydrophobic Fibers&gt; 
     The method for textile printing of a hydrophobic fiber as described in the present embodiment is a method for printing on a hydrophobic fiber using the colored dispersion liquid as described in the present embodiment described above. Methods for printing of a hydrophobic fiber are roughly classified into a direct printing method and a sublimation transfer method. 
     The direct printing method includes a printing step in which a droplet of the colored dispersion liquid is adhered to a hydrophobic fiber by an inkjet printer to obtain a recorded image such as a letter or a pattern, a fixing step in which the dye in the colored dispersion liquid adhered to the hydrophobic fiber in the printing step is fixed to the hydrophobic fiber by heat, and a washing step of washing the unfixed dye remaining in the hydrophobic fiber. 
     The fixing step is generally performed by known steaming or baking. Examples of the steaming include a method in which a dye is attached (also referred to as wet heat fixing) to a hydrophobic fiber by treating the hydrophobic fiber with a high-temperature steamer for about 10 minutes at usually 170 to 180° C., or a high-pressure steamer for about 20 minutes at usually 120 to 130° C. Examples of the baking (thermosol) include a method in which a dye is attached (also referred to as dry heat fixation) to a hydrophobic fiber by treating the hydrophobic fiber at 190 to 210° C. for about 6 to 120 seconds. 
     The washing step is a step of washing the obtained fiber with warm water and, if necessary, with ambient temperature water. The warm water or ambient temperature water to be used for washing may contain a surfactant. The washed hydrophobic fiber is also preferably dried, usually at 50 to 120° C. for 5 to 30 minutes. 
     On the other hand, the sublimation transfer method includes printing by adhering a droplet of the colored dispersion liquid to an intermediate recording medium by an inkjet printer to obtain a recorded image, such as a letter, a pattern, etc., and transferring by contacting a hydrophobic fiber with a surface of the intermediate recording medium on which the colored dispersion liquid is adhered to transfer the recorded image to the hydrophobic fiber by heat treatment. 
     As the intermediate recording medium, it is preferable that the dye in the adhered colored dispersion liquid does not aggregate on its surface and the intermediate recording medium does not interfere with sublimation of the dye when transfer of the recorded image to the hydrophobic fiber is performed. As an example of such an intermediate recording medium, a paper on the surface of which an ink-receiving layer is formed with inorganic fine particles such as silica may be mentioned, and a special paper for inkjet, or the like may be used. 
     The heat treatment in the transfer step typically includes dry heat treatment at about 190 to 200° C. 
     The method for textile printing of a hydrophobic fiber as described in the present embodiment may further include a pretreating step of pretreating the hydrophobic fiber for the purpose of preventing bleeding or the like. Examples of this pretreatment step include a step of imparting an aqueous solution (pretreatment liquid) containing a sizing agent, an alkaline substance, a reduction inhibitor, and a hydrotropic agent to a hydrophobic fiber before the colored dispersion liquid is adhered. 
     Examples of the sizing agent include natural gums such as guar, locust bean, etc.; starches; marine algae such as sodium alginate, Gloiopeltis, etc.; plant skin such as pectic acid, etc.; fibrous derivatives such as methyl fibrin, ethyl fibrin, hydroxyethyl cellulose, carboxymethyl cellulose, etc.; processed starch such as carboxymethyl starch, etc.; synthetic glue such as polyvinyl alcohol and polyacrylate esters; and the like. Sodium alginate is preferable. 
     The alkaline substance includes, for example, alkali metal salts of inorganic acids or organic acids; salts of alkaline earth metals; compounds which liberate alkali when heated; and the like. Alkali metal hydroxides and alkali metal salts are preferable. Examples include alkali metal hydroxides such as sodium hydroxide, calcium hydroxide, etc.; alkali metal salts of inorganic compounds such as sodium carbonate, sodium bicarbonate, potassium carbonate, sodium dihydrogen phosphate, disodium hydrogen phosphate, sodium phosphate, etc.; alkali metal salts of organic compounds such as sodium formate, sodium trichloroacetate, etc.; and the like. Sodium bicarbonate is preferable. 
     As the reduction inhibitor, sodium meta-nitrobenzenesulfonate is preferable. As the hydrotropic agent, ureas such as urea, dimethylurea, etc. may be exemplified, and urea is preferable. 
     With regard to the sizing agent, the alkaline substance, the reduction inhibitor, and the hydrotropic agent, any one type may be used alone, or two or more types may be used in combination. 
     The mixing ratio of each component in the pretreating liquid is, for example, 0.5 to 5% by mass of the sizing agent, 0.5 to 5% by mass of sodium bicarbonate, 0 to 5% by mass of sodium meta-nitrobenzenesulfonate, 1 to 20% by mass of urea, and the balance of water. 
     Methods of attaching the pretreating liquid to hydrophobic fibers include, for example, a padding method. The aperture ratio of padding is preferably about 40 to 90%, and more preferably about 60 to 80%.

     &lt;Evaluation&gt; 
     The following evaluation tests were performed using the aqueous orange inks 1 to 10 prepared as described above. Results are indicated in Tables 5 and 6 below. 
     [Particle Size Change Test] 
     With respect to the aqueous orange inks after storage at 60° C. for 5 days, the median diameter (D50, number-average particle diameter) of the colorant in the respective inks was measured using a MICRO TRAC UPA EX150 (manufactured by MicrotrackBEL Corp.) and evaluated based on the following criteria. A, B, or C represents a good evaluation, and D represents a poor evaluation. 
     —Evaluation Criteria— 
     
         
         A: D50 is below 140 nm. 
         B: D50 is 140 nm or more and less than 160 nm. 
         C: D50 is 160 nm or more and less than 170 nm. 
         D: D50 is 170 nm or more. 
       
    
     [Sedimentation Property Test] 
     Using an absorbance Abs 0  at a maximum absorption wavelength (λmax) around 420 nm measured at the time of ink preparation and an absorbance Abs 1  at a maximum absorption wavelength (λmax) around 420 nm measured after storage at 60° C. for 5 days by collecting a supernatant of the respective inks, a sedimentation rate was calculated according to the following equation. Note that the absorbance was measured for a diluted solution obtained by adding water to the inks and diluting them 2,000 times. 
       Sedimentation rate (%)={(Abs 0 −Abs 1 /Abs 0 ×}100
 
     Then, the calculated sedimentation rate was evaluated based on the following criteria. A or B represents a good evaluation, and C represents a poor evaluation. 
     —Evaluation Criteria—

     As is apparent from the results of Tables 5 and 6, all of the aqueous orange inks of Examples 9 to 16 prepared using the aqueous dispersions of Examples 1 to 8 had no significant increase in particle diameter after the storage at high temperature, thus containing few coarse particles, and having good sedimentation properties and excellent storage stability. Contrary to this, the aqueous orange inks of Comparative Examples 3 and 4 prepared using the dispersion liquids of Comparative Examples 1 and 2 were inferior in storage stability to the aqueous orange inks of Examples 9 to 16. 
     Examples 17 to 20: Preparation of Aqueous Dispersions 11 to 14 
     Glass beads with a 0.2 mm diameter were added to each of the mixtures of the respective components described in Table 7 below, and then the respective mixtures were subjected to a dispersion treatment in a sand mill for about 15 hours under water cooling. The obtained liquids were filtered through a glass fiber filter paper GC-50 (ADVANTEC Co., Ltd., pore diameter of a filter: 0.5 μm) to prepare aqueous dispersion liquids 11 to 14. In Table 7, the numerical value of each component indicates the number of parts added.

     &lt;Evaluation&gt; 
     Using the aqueous orange inks 11 to 14 prepared as described above, the above-described particle size change test, the sedimentation property test, and the following re-dispersibility evaluation test were performed. Results are indicated in Table 9 below. 
     [Re-Dispersibility Evaluation Test] 
     25 μL of each of the aqueous orange inks was dropped onto a glass petri dish and dried for 1 hour in a constant temperature and humidity machine at 60° C. To the dried product obtained, drops of ion-exchanged water in a volume of 10 mL were added at room temperature, and whether or not the dried product was re-dispersed was visually observed and the respective orange inks were evaluated based on the following criteria. The ink that can be re-dispersed is considered excellent due to ease of fixing clogged ink after drying. A, B, or C represents good evaluation, and D is poor in evaluation. 
     —Evaluation Criteria— 
     
         
         A: There was no residue and all of the clog was re-dispersed. 
         B: The residue remained a little, but most of the clog was re-dispersed. 
         C: The residue remained a lot, and the clog was somewhat re-dispersed. 
         D: No clog was re-dispersed.

     As is apparent from the results of Table 9, all of the aqueous orange inks of Examples 21 to 24 prepared using the aqueous dispersion liquids of Examples 17 to 20 had no significant increase in particle diameter after the storage at high temperature, thus containing few coarse particles, and having good sedimentation properties and excellent storage stability. Furthermore, the aqueous orange inks of Examples 21 to 24 (particularly, the aqueous orange inks of Examples 22 to 24 containing polyoxyethylene styrylphenyl ether sulfate-based dispersant) had good re-dispersibility as well. 
     Examples 25 to 28: Preparation of Aqueous Dispersions 15 to 18 
     Glass beads with a 0.2 mm diameter were added to each of the mixtures of the components described in Table 10 below, and the respective mixtures were subjected to a dispersion treatment in a sand mill for about 15 hours under water cooling. The obtained liquids were filtered through a glass fiber filter paper GC-50 (ADVANTEC Co., Ltd., pore diameter of a filter: 0.5 μm) to prepare aqueous dispersion liquids 15 to 18. In Table 10, the numerical value of each component indicates the number of parts added.

     As is apparent from the results of Table 12, all of the aqueous orange inks of Examples 29 to 32 prepared using the aqueous dispersion liquids of Examples 25 to 28 had no significant increase in particle diameter after the storage at high temperature, thus containing few coarse particles, and having good sedimentation properties and excellent storage stability. In addition, the aqueous orange inks of Examples 29 to 32 were also excellent in re-dispersibility. 
     Examples 33 to 42: Preparation of Aqueous Dispersions 19 to 28 
     Glass beads with a 0.2 mm diameter were added to each of the mixtures of the components described in Tables 13 and 14 below, and the mixtures were subjected to a dispersion treatment in a sand mill for about 15 hours under water cooling. The obtained liquids were filtered through a glass fiber filter paper GC-50 (ADVANTEC Co., Ltd., pore diameter of a filter: 0.5 μm) to prepare aqueous dispersion liquids 19 to 28. In Tables 13 and 14, the numerical values of each component indicate the number of parts added.

     As is apparent from the results of Tables 17 and 18, all of the aqueous orange inks of Examples 43 to 52 prepared using the aqueous dispersions of Examples 33 to 42 had no significant increase in particle diameter after the storage at high temperature, thus containing few coarse particles, and having good sedimentation properties and excellent storage stability. The aqueous orange inks of Examples 49 to 52 were also excellent in re-dispersibility. On the other hand, the aqueous orange ink of Comparative Example 6 prepared using the aqueous dispersion liquid of Comparative Example 5 was inferior in storage stability to the aqueous orange inks of Examples 43 to 52. 
     Examples 53 to 58: Preparation of Aqueous Orange Inks 30 to 35 
     Each of the aqueous dispersion liquids 3, 19, and 25 to 28 obtained in Examples 3, 33, and 39 to 42 and the components described in Table 19 below were mixed and stirred for 30 minutes, and then filtered through a glass fiber filter paper GC-50 (manufactured by Advantec Ltd., pore diameter of the filter: 0.5 μm) to obtain aqueous black inks 1 to 6. In Table 19, numerical values of the respective components indicate the number of parts added.

     Each of the aqueous orange inks 30 to 35 prepared as described above was filled into an inkjet printer (PX-504A, manufactured by EPSON Co., Ltd.), and intermediate recording media in each of which a single-color solid image of 100% Duty was printed were obtained, using TRNASJECT EcoII 8385 (basis weight: 95 g/m 2 ) as an intermediate recording medium. An ink adhering surface of each of the obtained intermediate recording media and polyester fabric (Teijin Tropical) were superimposed on each other, and then heat treatment was performed using a tabletop automatic flat pressing machine (AF-65TEN manufactured by Asahi Garment Machinery Co., Ltd.) under a condition of 200° C. for 30 seconds, whereby dyed products that were dyed by the sublimation transfer method were obtained. All of the dyed products could have desired colors. 
     Furthermore, using the aqueous orange inks 30 to 35 prepared as described above, the particle size change test and the sedimentation property test were performed. Results are indicated in Table 20 below.

     As is apparent from the results shown in Table 20, all of the aqueous orange inks of Examples 53 to 58 had no significant increase in particle diameter at the storage at high temperature, thus containing few coarse particles, and having good sedimentation properties and excellent storage stability. 
     Examples 59 to 64: Preparation of Aqueous Black Inks 1 to 6 
     The aqueous dispersion liquids 3, 19, and 25 to 28 obtained in Examples 3, 33, and 39 to 42 and the components described in Table 21 below were mixed and stirred for 30 minutes, and then filtered through a glass fiber filter paper GC-50 (ADVANTEC Co., Ltd., pore size of a filter: 0.5 μm) to prepare aqueous black inks 1 to 6, respectively. In Table 21, the numerical value of each component indicates the number of parts added.

     Each of the aqueous black inks 1 to 6 prepared as described above was filled into an inkjet printer (PX-504A, manufactured by EPSON Co., Ltd.), and intermediate recording media in each of which a single-color solid image of 100% Duty was printed were obtained, using TRANSJET EcoII 8385 (basis weight: 95 g/m 2 ) as an intermediate recording medium. An ink adhering surface of each of the obtained intermediate recording media and polyester fabric (Teijin Tropical) were superimposed on each other, and then heat treatment was performed using a tabletop automatic flat pressing machine (AF-65TEN manufactured by Asahi Garment Machinery Co., Ltd.) under a condition of 200° C. for 30 seconds, whereby dyed products that were dyed by the sublimation transfer method were obtained. 
     For each of the dyed products obtained, the dye density was measured using a spectroscopic colorimeter eXact (manufactured by X-Rite Inc.). Colorimetry was carried out under the conditions of a D65 light source, a viewing angle of 2° and status I. The reflectance R λ , at 400 to 700 nm for each of the dyed products was determined and Kubelka-Munk equation K/S=(1−R λ ) 2 /2R λ  was used to calculate K/S. Then, sigma K/S value, which is a sum of K/S values at each wavelength, was calculated. As a result, all of the aqueous black inks had the sigma K/S value of 400 or more, indicating a good color development. 
     Furthermore, using the aqueous black inks 1 to 6 prepared as described above, the above-mentioned particle size change test and the sedimentation property test were performed. Results are indicated in Table 22 below.
