DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fabric for ink-jet printing, a method for producing the same, and a method for ink-jet printing using the same.

[0002]

2. Description of the Related Art In recent years, printing apparatuses using ink-jet technology have been put to practical use, and high-definition printed fabrics have been produced in a simple process, and many improvements have been attempted.

[0003] Regarding the processing of general ink-jet fabrics, many proposals have been made mainly with respect to prevention of bleeding and improvement of color development. For example, Yoshida et al.
No. 55277, an ink jet dyeing fabric containing a compound which is substantially non-dyeable with respect to a dye to be dyed on a fabric material in an amount of 0.1 to 50% by weight based on the fabric material, and The disclosed inkjet dyeing method makes it possible to prevent bleeding in inkjet printing.

Japanese Patent Application Laid-Open No. 62-53492 discloses a printing method in which a recording liquid containing a water-soluble dye is applied to fabrics by an ink jet system, and then, if necessary, a dyeing treatment is performed. Viscosity at 25 ° C of 10
By disclosing a printing method in which a recording liquid receiving layer of 00 cP or more is formed, it is stated that ink can be received in a recording liquid receiving layer having fluidity to prevent bleeding and obtain a high-quality ink jet textile. ing.

In this example, a 100% cotton broad cloth is immersed in a recording liquid receiving layer liquid of 2200 cP, and then squeezed lightly to remove excess receiving layer liquid. Immediately after installation, the printer was attached to an ink-jet printer, printed on cotton fabric, then removed from the printer and ironed to fix the ink. We have obtained printed fabrics with a printer.

In another embodiment, a 15,000 cP recording liquid receiving layer agent is converted into a 50% aqueous solution to form a 65% cotton 35% hemp 35% cotton solution.
Coat with a bar coater at 80 ℃ 1
The printed fabric is obtained by performing hot air drying for a long time, and the printed fabric is printed using an ink jet printer, and is subjected to a dyeing treatment with an iron and a washing with a neutral detergent to obtain an ink jet printed fabric. The ink-jet printing cloth produced according to the above-described embodiment sufficiently satisfies the resolution of a straight line at 1.5 mm intervals, has no blurring or bleeding, and has a sufficient density. It is said that it can be applied to home print printing.

[0007]

However, in Japanese Patent Application Laid-Open No. 61-55277 by Yoshida et al., No consideration is given to the transportability of a general-purpose ink jet printer in any of the embodiments. Its application is limited to the field of industrial printing, which requires a special cloth transport.

Further, even the method disclosed in Japanese Patent Application Laid-Open No. 62-53492 is not sufficiently effective in preventing bleeding, and further improvement is required to achieve high-definition printing.

Further, in the case of cloth, unlike paper and the like, transport technology is difficult, and it is inevitable that the cloth transport section of the apparatus is complicated and large, so that problems in terms of apparatus cost and space saving remain. However, it is substantially difficult for a user to easily perform printing as desired with high definition. As the most preferable mode, it is conceivable to process the cloth so that the conventional paper transport system can be used almost as it is, but there is no example in which this point is sufficiently considered.

[0010] Accordingly, an object of the present invention is to solve the above-mentioned problems in conventional general ink jet printing fabrics,
That is, in addition to the dyeing technology problem of obtaining a clear and high-concentration dyed material without ink bleeding, in addition to operational problems such as ink fixability and transportability in the apparatus, and problems of detergency during soaping. It is an object of the present invention to provide a fabric for inkjet printing, which simultaneously satisfies the above requirements, a method for producing the same, and a method for inkjet printing.

[0011]

According to the present invention, a base fabric is prepared by using a stiffening agent containing sodium alginate having an average degree of polymerization of 80 to 120 or carboxymethyl cellulose having an ether degree of 0.65 to 0.9. Treat to Clark stiffness 1
A method for producing a fabric for ink jet printing which is a fabric of 0 to 400 or less, a fabric obtained by the method, and an ink jet printing method for printing the fabric by an ink jet method, heating, and then removing a stiffening agent by washing. provide.

[0012]

The present inventors have made improvements to the ink-jet printing fabric which can be used for a simple transport system, so as to simultaneously satisfy the various requirements as described above. By controlling the Clarke stiffness within a certain range by performing the treatment, it was found that various properties such as coloring property, washing property, dyeing rate, fixing property, bleeding property and transportability can be remarkably improved.

[0013] This phenomenon is achieved by limiting the Clark stiffness of the fabric, thereby optimizing the cloth transport accuracy, and maximizing the print accuracy even when printing is performed using various ink jet printers as conventionally reported. It seems that it can be done.

Further, by controlling the Clark stiffness of the fabric and limiting the stiffening agent, various properties such as color development, washability, dyeing rate, fixability, bleeding, and transportability are further improved. The inventor of the present invention has found that it is possible to do so.

[0015] In particular, the selection of a stiffening agent is a very delicate problem, and can be dealt with by various materials if attention is paid only to the point of transportation. In consideration of such factors, it is necessary to employ a specific material that is controlled to the molecular weight and the degree of etherification.

Next, the present invention will be described in detail with reference to preferred embodiments.

First, there is no particular limitation on the base fabric of the fabric of the present invention. Examples of the material include natural fibers such as cotton, silk, hemp, rayon, acetate, wool, nylon, polyester and acrylic. Fibers, semi-synthetic fibers and the like and derivatives thereof are mentioned. Among them, cationized cotton is particularly suitable because it is compatible with a simple printing system using an anionic dye. The term “cationization” as used herein refers to, for example, those treated with a reactive quaternary compound, chitosan, an anion-dyeable polymer coat, or the like.

The fibers are used singly or in a blend, and may be used in any form such as a woven fabric, a knitted fabric, and a nonwoven fabric.

The form of the fabric is a cut sheet shape or a roll shape.

The cationization is to introduce a cationic substance into the above-mentioned cloth by the following three methods. (1) Reactive addition of reactive quaternary amine compound to fiber (2) Coating of cationic inorganic fine particles and binder (use of cross-linking agent) (3) Application of anion-dyeable polymer (use of cross-linking agent) Specific examples of the reactive quaternary amine compound include the following compounds (1) to (13).

Examples of the resin binder used in combination with these cationic inorganic fine particles include gum arabic, casein, glue, soybean protein, urea resin, melamine resin,
Examples include polyacrylamide, polyamide, polyethyleneimine, sodium polyacrylate, polyvinyl alcohol, gelatin, starch, polyvinylpyrrolidone, keratin, methylcellulose, styrene / butadiene latex, and styrene / maleic anhydride copolymer.

Examples of the anion-dyeable polymer substance include gum arabic, casein, glue, soybean protein, urea resin, melamine resin, polyacrylamide, polyamide, polyurethane, polyethyleneimine, and a polymer containing a quaternary amino group.

As a crosslinking agent, a bifunctional epoxy compound,
Bisacrylamide, dimethylol ethylene urea, dimethylol propylene urea, dimethylol dihydroxy ethylene urea, methylated dimethylol dimethoxy ethylene urea and the like can be mentioned.

A solution containing these compounds is applied to the fabric. Alternatively, the cationic substance is contained in the cloth by impregnating the cloth with the solution, then heating and curing, washing with water, and drying. The amount of these substances applied to the fabric varies depending on the treatment method and the type of the applied compound, but is generally preferably about 0.01 to 30% by weight based on the weight of the fabric.

The above-mentioned fibers are used alone or in a blend, and can be used in any form such as a woven fabric, a knitted fabric and a non-woven fabric.

The shape of the fabric is a cut sheet shape or a roll shape.

Next, the Clark stiffness that characterizes the ink jet textile printing fabric of the present invention using the above-described base fabric is in the range of 10 to 400, preferably 15 to 350, more preferably 20 to 300. Clark stiffness of 10

One of the stiffening agents for achieving the above-mentioned rigidity is sodium alginate having an average degree of polymerization of 80 to 120, more preferably 85 to 115. The degree of polymerization can be easily determined by measuring the viscosity of a 1% aqueous solution or by gel permeation chromatography. Here, the average degree of polymerization is based on weight average. When the average degree of polymerization is less than 80,
There is a problem in terms of the dyeing ratio, and when it exceeds 120, there is an obstacle in terms of detergency.

Further, another example of the above-mentioned stiffening agent is carboxymethyl cellulose having a degree of etherification of 0.65 to 0.9, more preferably 0.7 to 0.85. The degree of etherification is generally specified by IR or NMR. When the degree of etherification is less than 0.65, there is a problem in terms of coloring and dyeing properties, and when it exceeds 0.9, there is a problem in terms of detergency and bleeding.

Further, in addition to the above, a conventional pretreatment can be used in combination with the fabric for ink jet textile printing of the present invention. In particular, for a fabric dyed with a reactive dye, one containing 0.01 to 5% by weight of an alkaline substance with respect to the weight of the dry fabric to control the moisture content in the fabric, and is common to general fabrics As a treating agent, one or more of a substance selected from the group consisting of a water-soluble metal salt, a water-soluble polymer, urea, thiourea and a surfactant is used in an amount of 0.01 to 20.

Further, examples of the synthetic polymer include a polyvinyl alcohol-based compound, a polyethylene oxide-based compound, an acrylic acid-based water-soluble polymer, and a maleic anhydride-based water-soluble polymer. Among them, polysaccharide polymers and cellulose polymers are preferable.

Examples of the water-soluble metal salts include those which form typical ionic crystals, such as halides of alkali metals and alkaline earth metals.
And 10 to 10. Representative examples of such compounds include, for example, NaC
1, Na ₂ SO ₄ , KCl, CH ₃ COONa and the like, and examples of the alkaline earth metal salts include CaCl ₂ and MgCl ₂ . Among them, salts of Na, K, and Ca are preferable.

As the surfactant, anionic, cationic, amphoteric or nonionic surfactants are used. Typically, anionic surfactants include higher alcohol sulfates, naphthalene derivative sulfonates, and cationic surfactants. Examples include quaternary ammonium salts, imidazoline derivatives for amphoteric compounds, polyoxyethylene alkyl ethers, polyoxyethylene propylene block polymers, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters, and ethylene oxide adducts of acetylene alcohol for nonionic compounds.

The printing ink used for the ink-jet printing fabric of the present invention is not particularly limited as long as it can dye the fibers of the base fabric, but is composed of an aqueous liquid medium containing various dyes. Ink jet printing inks are preferably used.

As the dye, a dye which can be dyed on fibers constituting the fabric is dissolved or dispersed. Among them, an ink using an acid dye, a direct dye, a reactive dye, a basic dye, or a disperse dye is preferable when the fabric of the present invention is used.

One or more of these dyes are contained in the ink and can be used in combination with dyes having different hues. The amount of the dye used is generally from 1 to the total amount of the ink. The range is 30% by weight, preferably 1.5 to 25% by weight, more preferably 2 to 20% by weight. If the amount is less than 1% by weight, the color density is insufficient. On the other hand, if the amount exceeds 30% by weight, the ink ejection suitability becomes insufficient.

Water, which is a suitable component of the liquid medium constituting the ink used in the ink jet printing method of the present invention, is
30 to 90% by weight, preferably 40% by weight based on the total amount of the ink

According to the ink jet printing method of the present invention, the above-described ink jet printing fabric of the present invention is printed using the above-described printing ink. The ink jet recording method to be used may be any conventionally known ink jet recording method, for example, a method described in JP-A-54-59936,
The most effective method is a method in which the ink that has undergone the action of thermal energy causes a sudden change in volume, and the ink is ejected from the nozzles by the action force resulting from this state change. In such a system, stable printing can be performed by performing recording on the ink jet textile printing fabric of the present invention.

Further, as conditions under which a particularly effective printing method can be obtained, it is desirable that the discharged droplets be 20 to 200 pl and the ink ejection amount be 4 to 40 nl / mm ² .

As an example of an apparatus suitable for performing printing using the ink-jet printing cloth of the present invention, thermal energy corresponding to a recording signal is applied to ink in a chamber of a recording head, and droplets are formed by the thermal energy. An apparatus for generating the light is mentioned, which will be described below.

FIGS. 1, 2 and 3 show examples of the configuration of a head which is a main part of the apparatus.

The head 13 includes a glass, ceramic or plastic plate having a groove 14 through which ink passes, and a heating head 15 used for thermal recording (a head is shown in the figure, but is not limited to this). And obtained by bonding. The heating head 15 includes a protective film 16 made of silicon oxide or the like, and aluminum electrodes 17-1 and 17-.
2, a heating resistor layer 18 made of nichrome or the like, a heat storage layer 19, and a substrate 20 having good heat dissipation properties such as alumina.

The ink 21 has a discharge orifice (fine hole) 2
2, and the meniscus 23 is formed by the pressure P.

When an electric signal is applied to the electrodes 17-1 and 17-2, the area of the heating head 15 indicated by n rapidly generates heat, and bubbles are generated in the ink 21 in contact with the area, and the pressure is increased. As a result, the meniscus 23 protrudes, the ink 21 is ejected, the orifice 22 becomes a recording droplet 24, and flies toward the fabric 25 used in the present invention. FIG. 3 shows an external view of a multi-head in which many heads shown in FIG. 1 are arranged. The multi-head is a glass plate 2 having a multi-groove 26.
7 and a heating head 28 similar to that described with reference to FIG. FIG. 1 is a cross-sectional view of the head 13 along the ink flow path, and FIG. 2 is a cross-sectional view taken along line AB in FIG.

FIG. 4 shows an example of an ink jet recording apparatus incorporating such a head.

In FIG. 4, reference numeral 61 denotes a blade as a wiping member, one end of which is held by a blade holding member to become a fixed end, and forms a cantilever. The blade 61 is provided at a position adjacent to a recording area of the recording head, and in the case of this example, is held in a form protruding into the movement path of the recording head. Reference numeral 62 denotes a cap, which is disposed at a home position adjacent to the blade 61, and has a configuration in which the cap moves in a direction perpendicular to the direction in which the print head moves and comes into contact with the ejection port surface to perform capping.
Further, an absorber 63 is provided adjacent to the blade 61 and, like the blade 61, is held in a form protruding into the movement path of the recording head. The blade 61, the cap 62, and the absorber 63 constitute an ejection recovery section 64, and the blade 61 and the absorber 63 remove water, dust, and the like from the ink ejection port surface.

Reference numeral 65 denotes a recording head which has discharge energy generating means and discharges ink to a fabric facing a discharge port surface provided with discharge ports to perform recording. 66 denotes a recording head on which the recording head 65 is mounted. It is a carriage for moving. The carriage 66 is slidably engaged with the guide shaft 67, and a part of the carriage 66 is connected to a belt 69 driven by a motor 68 (not shown). As a result, the carriage 66 can move along the guide shaft 67, and the recording head 65 can move the recording area and the area adjacent thereto.

Reference numeral 51 denotes a cloth feeding unit for inserting a cloth, and 52 denotes a cloth feed roller driven by a motor (not shown).
With these configurations, the cloth is supplied to a position facing the discharge port surface of the recording head, and is discharged to a discharge section provided with a discharge roller 53 as recording proceeds.

In the above configuration, when the recording head 65 returns to the home position at the end of recording or the like, the cap 62 of the head recovery unit 64 is retracted from the moving path of the recording head 65, but the blade 61 protrudes into the moving path. I have. As a result, the ejection port surface of the recording head 65 is wiped. When capping is performed with the cap 62 in contact with the ejection surface of the recording head 65, the cap 62 moves so as to protrude into the movement path of the recording head.

When the recording head 65 moves from the home position to the recording start position, the cap 62 and the blade 61 are at the same position as the position at the time of wiping described above. As a result, the ejection port surface of the recording head 65 is also wiped during this movement.

The movement of the print head to the home position described above is performed not only at the end of printing or at the time of ejection recovery, but also at a predetermined interval while the printing head moves through the printing area for printing. Position, and the wiping is performed along with the movement.

As described above, the printing ink applied to the ink jet textile printing fabric of the present invention by the method of the present invention is:
In this state, it is merely attached to the fabric, so that it is preferable to continue the step of fixing the dye to the fiber and the step of removing the unfixed dye. Such a reaction fixing step and a method of removing unreacted dye may be a conventionally known method, for example, a steaming method, an HT steaming method,
After the treatment by the thermofix method or the like, the stiffening agent can be removed by washing to obtain a printed matter.

When a fabric which can be dyed with a reactive dye is dyed without using an alkali agent beforehand, an alkaline pad steam method, an alkaline blotch steam method, an alkaline shock method, an alkaline shock method, or the like may be used. After treatment by the cold fix method or the like, the printed material can be obtained by removing the stiffening agent by washing.
