Description

  The present invention relates to a fabric for inkjet recording and a method for producing a fabric for inkjet recording.

  2. Description of the Related Art Conventionally, a technique for recording on a fabric by using an ink-jet method using a color material has been developed. In general, inkjet recording fabrics are bonded with a detachable paper or film on the back side of the print surface to ensure the dimensional stability of the fabric and prevent ink back-through and image distortion during printing. (For example, refer to Patent Document 1).

  By the way, the fabric for inkjet recording is provided in a roll state having a width of 24 or 36 inches and a length of about 20 to 30 m. Therefore, it is necessary for the user to provide a process of cutting the ink-jet recording fabric into a size suitable for the use form after printing. Since the inkjet recording fabric is made of a fiber such as polyester, the fiber may be broken or the fabric may be broken by a normal cutting method (hand cutting or the like). As a method for preventing this, there is a so-called “melt cut” method in which the fibers are cut while being heated to weld the fibers.

However, in order to perform “melting cut”, a large-scale facility such as a hot-melting cutter or a heat-resistant mat is required, which cannot be achieved by general users.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments suitable for the invention will be described in detail with reference to the drawings.

1. Inkjet Recording Fabric FIG. 1 is a perspective view showing a part of an inkjet recording fabric according to this embodiment.

  As shown in FIG. 1, the inkjet recording fabric 100 according to the present embodiment is obtained by bonding a peelable film body 12 to the back surface of the printing surface of the fabric 10. By bonding the film body 12, the shape of the fabric can be fixed, so that distortion of the image during printing can be prevented. In addition, it is possible to prevent the ink from passing through during printing.

  The film body 12 is not particularly limited as long as it has a strength that can fix the shape of the fabric, and various materials can be used. Examples of the material of the film body 12 include paper such as glassine paper and special high-quality paper for processing, and PET-based and OPP-based resin laminate films. The film body 12 may have ink absorbability. When the ink absorbs, the film body 12 absorbs ink that has oozed out on the back side of the printing surface of the fabric, thereby preventing contamination of the fabric with ink.

  In addition, in so-called borderless printing in which printing is performed without forming a blank portion around the recording medium, it is difficult to print the entire surface of the recording medium without forming a blank. Things have been done. In this case, the ink that has been printed out is contaminated with a platen of the printer (a member that supports the recording medium from below at the printing position). However, the use of the inkjet recording fabric according to the present embodiment has an advantage that it is not necessary to provide an ink absorbing material on the platen because the film body absorbs the ink that has been printed out. In such an embodiment, the plurality of fabrics are preferably bonded to the film body with a gap.

  The thickness of the film body 12 may be 20 to 500 μm. If the thickness of the film body 12 is less than 20 μm, it may be broken due to insufficient strength. On the other hand, when the thickness exceeds 500 μm, it may be difficult to wind in a roll shape at the winding portion. The film body 12 is peeled off after printing.

  The paste material for bonding the film body 12 is preferably applied to or sprayed on the film body 12 in advance so that the cloth to be printed is not affected, and then the fabric 10 is bonded. The paste material may be either water-soluble or oil-soluble, and examples thereof include polyvinyl acetate, acrylic-modified resin, ethylene-vinyl acetate copolymer, SBR latex, polyvinyl alcohol, and starch.

  Examples of the fabric 10 include woven fabric, knitted fabric, and non-woven fabric. Examples of the material for the fabric include, for example, semi-synthetic fibers such as acetate and triacetate; synthetic fibers such as polyester, nylon, and acrylic; and those using one or more of them in the form of mixed spinning or weaving. it can. In this, although it demonstrates in detail later, it is preferable to use a polyester fiber whose melting | fusing point is comparatively low as about 120 degreeC from a viewpoint that a fabric must be melt-cut.

  As shown in FIG. 1, in the inkjet recording fabric 100 according to the present embodiment, only the fabric 10 is cut into a standard size in advance. If the fabric 10 is cut to a standard size in advance, a step of cutting by the user after printing on the fabric 10 is not required, and an indoor / outdoor banner printed on the fabric 10 simply by peeling the mount 12 attached to the fabric 10 and the like Can make banners, etc.

  When the user cuts the fabric by hand, fiber fraying on the cut surface, breakage of the fabric, and the like often occur. Moreover, even if it respond | corresponds by sticking a transparent tape on a cut surface in order to repair this, an external appearance will be impaired. These problems can be solved by cutting the fabric into a standard size in advance. Here, the standard size generally refers to a size used for an indoor / outdoor banner, a pocket, or the like, but is not particularly limited to these sizes, and means a size according to a usage pattern on the user side.

  In order to cut only the fabric 10, a cutting method called “melting cut” is applied. “Melting cut” is a method of cutting while welding a cut portion of a fabric using a heat cutter that maintains a temperature at which the fabric can be melted but the film body cannot be melted. By melting and cutting only the fabric, it is possible to prevent the occurrence of fiber sag and fabric tear on the cut surface 10b. In order to perform melt cutting, large equipment such as a heat cutter and a heat-resistant mat is required, so that it has been a great effort and cost to perform on the general user side. The inkjet recording fabric 100 can significantly reduce the labor and cost on the user side.

  The inkjet recording fabric 100 according to this embodiment can be printed by an inkjet method using pigment ink or dye ink, but it is preferable to use pigment ink. This is because the ink-jet recording fabric is often used for applications such as indoor and outdoor banners, banners, hanging curtains, and the like, and therefore light resistance is required. Also, pigment ink has better color development than dye ink, and images can be recognized even when viewed from the back side.

  When pigment ink is used as the ink, if the printing surface of the fabric is previously processed with an ink acceptor, “bleeding” of the fabric surface can be suppressed. As a method of processing a fabric with an ink acceptor, for example, there is a method of processing the surface of the fabric with a treatment liquid (ink acceptor) containing a cationic resin. By this method, an ink receiving layer can be formed on the surface of the fabric. When an ink receiving layer containing a cationic resin is formed on the surface of the fabric, not only “bleeding” of the fabric surface can be suppressed, but also water resistance can be improved.

  Pigment inks used in the ink jet system have an ionic polymer added to enhance the pigment dispersion effect by electric repulsion. By using a fabric to which a polymer material added to the pigment ink and a resin material that becomes a counter ion is used, the bonding force between the ink molecules and the resin molecules in the image forming portion is enhanced.

  Examples of the cationic resin include polymers and oligomers such as acrylamide, vinylamine, allylamine, ethyleneimine, and dicyandiamide. These resins may be used alone or in combination of two or more. The molecular weight of the cationic resin is preferably in the range of 1000 to 10,000. If it is within the above range, the resin can be uniformly applied to the fabric.

  A divalent or higher valent metal may be added to the treatment liquid containing the cationic resin. These metal ions have the effect of reducing the refractive index of light and improving the clarity. Examples of the divalent metal include Cu, Zn, Ca, Sn, and Ba. Examples of the trivalent metal include Al and Fe. In addition, in order to obtain the same effect as the above divalent or higher metals, inorganic materials such as alumina hydrate, colloidal silica, metal oxide, water-insoluble collagen fine particles, oil emulsion, polysulfonic acid ether, wax emulsion, Organic substances such as fatty alcohol aliphatic esters, polyethylene glycol fatty acid esters and stearic acid esters can also be added.

  Furthermore, a component that exhibits an ink absorption performance and prevents ink permeation and diffusion into the fabric layer may be included in the processing liquid during printing. The substance that can be expected to have the above effects can be selected from synthetic resins such as polyurethane, polystyrene and polyacryl, latexes such as urethane rubber and butadiene rubber, and mixtures thereof. The composition of the fabric used and the color material used Further, it is necessary to select appropriately depending on the molecular weight.

  Further, if necessary, the treatment liquid may contain a penetrant, a pH adjuster and the like. Examples of the penetrant include alcohols such as octyl alcohol and isopropyl alcohol, and general surfactants. Examples of the pH adjuster include acetic acid, ammonium acetate, sodium carbonate, ammonium sulfate and the like.

  Examples of a method for applying a treatment liquid comprising a cationic resin include a method in which the treatment liquid is directly applied or sprayed on a fabric, and a method in which the treatment liquid is formed on a film and laminated. Examples of the direct application or spraying method include a gravure method, a coating method, a mangle pad method, and the like. In addition, as a means for forming and laminating the film, a laminating method or the like can be given. An ink receiving layer is formed on the fabric surface by processing with the above processing solution. Printing is performed on the surface of the fabric on which the ink receiving layer is formed by an inkjet method.

2. Method for Producing Inkjet Recording Fabric A method for producing an inkjet recording fabric according to an embodiment of the present invention includes a first step in which a peelable paper or film is bonded to one surface of a fabric, and the fabric is fixed. A second step of melting and cutting to size. Hereinafter, specific examples of the method for producing an inkjet recording fabric according to an embodiment of the present invention will be described with reference to the drawings. However, the method for producing an inkjet recording fabric according to an embodiment of the present invention is limited thereto. Is not to be done.

2.1 First Step FIG. 2 is a diagram schematically showing a first step of the method for manufacturing an ink jet recording fabric according to the present embodiment. As shown in FIG. 2, the first step is a step in which the fabric 10 and the film body 12 are bonded together via the paste material 16. As described above, the fabric 10 can have an ink receiving layer formed on the printing surface in advance.

  First, while rotating the fabric roll 10a and the film body roll 12a at the same speed, the paste material 16 is applied to the mount 12 from the paste supply section 14 so as to be uniform. Examples of the method for applying the paste material 16 include spray coating and roll coating. Next, the fabric 10 and the film body 12 are bonded together by the bonding roll 18. And the fabric roll 22 for inkjet recording can be obtained by winding in the winding part 20 so that the printing surface of the fabric 10 may become the surface.

2.2 Second Step FIG. 3 is a diagram schematically showing a second step of the method for manufacturing an ink jet recording fabric according to the present embodiment. As shown in FIG. 3, the second step is a step of cutting only the fabric 10 of the inkjet recording fabric roll 22 manufactured in the first step into a standard size. That is, the film body 12 must not be cut. Therefore, in the second step, a method called “melting cut” described above is applied. Specifically, only the fabric 10 of the inkjet recording fabric 22 is melt-cut using a heat cutter 24 that maintains the temperature at which the fabric 10 is melted and the film body 12 is not melted. According to this method, by using the film body 12 having a melting point higher than that of the fabric 10, it is possible to cut while welding only the fabric 10. For example, when a polyester fiber is used as the material of the fabric 10, the polyester fiber melts in the vicinity of 120 ° C., so the temperature of the heat cutter 24 may be set to 130 to 200 ° C. Moreover, since the film body 12 can be cooled if the cooling part 24 is provided in the film body side below the heat cutter 24, the melt cut of the film body 12 can be prevented. The heat cutter 24 may be a rotary type having a plurality of cutting portions as shown in FIG. 3, or may have a single cutting portion and move up and down. The inkjet recording fabric 22 cut to a standard size by the heat cutter 24 is completed by being wound by the winding unit 28 so that the printing surface of the fabric 10 becomes the surface.

2.3 Modification Example In the above embodiment, after the fabric and the backing sheet are bonded, only the fabric is melt-cut to a standard size. As a modified example, the following method can be applied.

  Inkjet recording fabrics that have been cut to a standard size in advance can be bonded one by one to a mount or the like on which a paste material is uniformly applied. Also in this modified example, it is preferable to melt-cut the inkjet recording fabric. This is because, when the melt cutting is performed, the cut portion can be cut while being welded, so that it is possible to prevent occurrence of fiber fraying and fabric tearing on the cut surface. Also by this modification, the fabric can be bonded to one surface of the film body with a gap. According to this method, there is an advantage that the length of the gap can be easily adjusted.

  The present invention is not limited to the above-described embodiments, and various modifications can be made. For example, the present invention includes substantially the same configuration (for example, a configuration having the same function, method, and result, or a configuration having the same purpose and effect) as the configuration described in the embodiment. In addition, the invention includes a configuration in which a non-essential part of the configuration described in the embodiment is replaced. In addition, the present invention includes a configuration that achieves the same effect as the configuration described in the embodiment or a configuration that can achieve the same object. In addition, the invention includes a configuration in which a known technique is added to the configuration described in the embodiment.
