Description

  The present invention relates to an ink jet recording sheet that is unlikely to fray when the sheet is cut, and a method for manufacturing the ink jet recording sheet. More specifically, the present invention relates to an ink jet recording sheet suitable for a hanging curtain or a banner used indoors and outdoors, and a method for manufacturing the ink jet recording sheet.

  Inkjet printing apparatuses (inkjet printers) targeting substrates such as paper and resin sheets have become widespread. According to these printing apparatuses, an ink-jet print product having a high density and clear full color printing can be obtained. Therefore, these printing apparatuses are widely used for OA use or home use.

  Recently, as a base material to replace paper and a resin sheet, a fabric that is lightweight, has high flexibility, and has excellent durability and tear strength has been attracting attention. Fabrics are preferred because of their unique texture, and products that are sold in A4 size are becoming popular as base materials for sheets for small-sized inkjet printers used in OA and homes. In addition, fabrics of large sizes such as banners and tapestry are used as a base material for advertising curtains regardless of whether they are indoors or outdoors.

  However, the fabric is prone to fraying, and due to this fraying, there is a possibility of causing a problem of conveyance failure or clogging of the head nozzle due to rubbing between the ink-jet head and the fabric, and in the worst case, causing a printer failure problem. is there. Therefore, a fabric recording medium that solves the above problems and can be printed even by an individual user is highly desired.

  Conventionally, a method for preventing fraying of a substrate in inkjet printing has been proposed. In Patent Document 1, after cutting a printing medium material, a process for exposing the cut part to a flame or a process for fixing the cut part with a resin is manufactured, and this is used for ink jet printing. Has been proposed.

  Patent Document 2 proposes a printing fabric provided with a printing ink receiving layer on the surface and / or inside of the fabric and a resin layer on the back surface. Patent Document 3 proposes a printing sheet fabric in which a porous layer is formed on one side of a base fabric and a resin coating layer is formed on the other side.

Japanese Patent Laid-Open No. 7-070951 JP 2012-086508 A JP 2002-309489 A

  However, according to the method described in Patent Document 1, it is necessary to increase the manufacturing cost because it is necessary to increase the number of processes such as the curling of the end of the fabric by exposure to a flame, the exposure to a flame, and the process of fixing with a resin. There is a problem of becoming. Further, according to the methods described in Patent Document 2 and Patent Document 3, a sufficient fraying prevention effect cannot be obtained. For this reason, an ink jet recording material using a fabric has not yet been obtained with an ink jet recording sheet having a low cost and an excellent fraying prevention effect.

  The present invention has been made in view of such conventional problems, and is an inkjet recording sheet that can prevent poor conveyance due to fraying of the yarn or poor printing due to nozzle clogging when performing inkjet output at low cost. And it aims at providing the manufacturing method of the sheet | seat for inkjet recording.

  An ink jet recording sheet according to one aspect of the present invention that solves the above problems includes a fabric provided with a coating agent and an ink receiving layer provided on the fabric, and the coating agent has a glass transition point of 10 to 10. It is 40 degreeC and is provided more than the thickness of the said fabric.

  Hereinafter, an ink jet recording sheet according to an embodiment of the present invention will be described. The ink jet recording sheet according to this embodiment includes a fabric provided with a coating agent and an ink receiving layer. Hereinafter, each configuration will be described.

(Fabric)
The fabric is a base material for an ink jet recording sheet, and is provided with a coating agent. In addition, as will be described later, an ink receiving agent is applied to the fabric to form an ink receiving layer.

  As fabrics, inorganic fibers including glass fibers, carbon fibers, alumina fibers, etc., synthetic fibers such as nylon fibers, polyester fibers, acrylic fibers, semi-synthetic fibers such as acetate, recycled fibers such as rayon, cotton, hemp, etc. Any of the organic fibers including natural fibers can be used. Among these, the fabric is preferably organic fibers for reasons such as the texture as the fabric and the transportability of the printer. Among these, the fabric is preferably a polyester fiber having excellent tensile strength and tear strength and high form stability.

  A coating agent is mix | blended in order to coat | cover a fabric and to prevent fraying. In this embodiment, the coating agent has a glass transition point (hereinafter also simply referred to as Tg) of 10 ° C. or higher. Moreover, Tg is 40 degrees C or less, and it is preferable that a coating agent is 32 degrees C or less. When the Tg of the coating is 10 to 40 ° C., the viscosity of the coating is appropriate. Moreover, the fabric coated with such a coating agent is less likely to fray. Furthermore, when the Tg of the coating agent is 10 to 40 ° C., the fabric provided with such a coating agent does not adversely affect the transportability in the printer while leaving the texture as the fabric.

  The coating agent of this embodiment is provided with respect to the fabric more than the thickness of the fabric. In the present embodiment, “the coating agent is applied more than the thickness of the fabric” means that the coating agent adheres to the inside of the fabric and also adheres to both surfaces of the fabric. Whether or not the coating agent adheres to the inside of the fabric can be confirmed by, for example, whether or not the filaments adhere to each other with an electron microscope. Moreover, it can be confirmed whether it has adhered to the fabric surface by measuring the change of the glossiness of the fabric surface before and behind provision of a coating agent. Moreover, a coating agent is provided so that at least one part may be coat | covered among the surfaces of a fabric. The coating agent is preferably applied so as to cover the entire surface of the surface of the fabric.

  A padding method, a spray method, an ink jet method, or the like can be employed as a method for applying the coating agent beyond the thickness of the fabric. Among these, the padding method is preferable from the viewpoint of easily covering the fabric uniformly. The padding method is a method in which a fabric is passed through a coating material stored in a bathtub and immersed, and then squeezed by a roll. The step by the padding method may be performed once or a plurality of times as long as the coating agent can be applied more than the thickness of the fabric. The treatment liquid by the padding method preferably has a low solid content because there are problems such as easy gumming up and drying when the coating agent has a high solid content. The solid content of the coating agent is preferably 20% or less.

  The coating agent can be selected from an acrylic resin, a urethane resin, a polyester resin, and the like according to necessary performance such as flame resistance and water resistance. A coating agent may be used individually from these resin, and may be used in mixture. The form of the coating agent may be any of an emulsion, an aqueous solution, and an oil solution. Among these, the coating agent is preferably an acrylic emulsion from the viewpoints of physical properties, environment, and cost. In addition, it is possible to select a urethane resin and a polyester resin depending on required physical properties such as flameproof performance. Examples of the acrylic resin include all acrylic resins, acrylic silicone resins, acrylic styrene resins, and acrylic urethane resins.

  The coating agent may be introduced with a crosslinking group for improving the adhesion between the resin particles or added with a crosslinking agent to such an extent that the texture of the fabric is not impaired. As such a crosslinking group, a carbodiimide group, an oxazoline group, an aziridine group, an isocyanate group, etc. are illustrated as what reacts with the functional group which a coating resin component has. Examples of such a crosslinking agent include carbodilite (manufactured by Nisshinbo Chemical Co., Ltd.), Epocross (manufactured by Nippon Shokubai Co., Ltd.), and the like. In addition, a wetting agent for allowing the coating agent to penetrate into the fabric may be added. By improving the permeability to the fabric, the coating agent can not only fill the voids of the fabric, but also reinforce the yarns constituting the fabric. Furthermore, the coating agent may be added with an antifoaming agent, a solvent, a thickener, a flame retardant, etc. as other prescriptions.

  The viscosity of the coating agent is preferably adjusted to 100 mPa / s or less. When the viscosity is adjusted to such a viscosity, the coating agent can be applied more uniformly because the permeability to the fabric is increased. For example, the viscosity can be measured using a BM viscometer (manufactured by Toki Sangyo Co., Ltd.) in a 25 ° C. environment under a rotor No. It can be measured under the condition of 4, 60 rpm.

Returning to the description of the entire fabric, the fabric weight is preferably 50 g / m ² or more. The fabric weight is preferably 300 g / m ² or less. On the other hand, the application amount of the coating agent in the basis weight is preferably 10 g / m ² or more after drying. Moreover, it is preferable that the application amount of the coating agent in this basis weight is 40 g / m ² or less after drying. When the fabric weight is 50 to 300 g / m ² and the amount of the coating agent applied to the fabric in this weight range is 10 to 40 g / m ² , the texture of the fabric coated with the coating is impaired. Therefore, fraying can be sufficiently prevented.

(Ink receiving layer)
The ink receiving layer is a layer formed on the base material in order to absorb ink described later and fix color materials such as dyes and pigments. The ink receiving agent that constitutes the ink receiving layer is not particularly limited. As an example, the ink acceptor is a water-swellable polyurethane resin.

  Examples of water-swellable polyurethane resins include Pascall (Meisei Chemical Co., Ltd.), Pateracol (registered trademark), Hydran (DIC Corporation), Superflex (registered trademark) (Daiichi Kogyo Seiyaku Co., Ltd.), etc. Is exemplified. Examples of the form of the water-swellable polyurethane resin include a wide variety of known materials such as an aqueous solution or dispersion, or a modified polymer in which an anionic residue or a cationic residue is introduced into the above resins. The water-swellable polyurethane resin is relatively soft and does not impair the fabric texture. In addition, the water-swellable polyurethane resin is rich in water-swellability and excellent in ink receptivity. Furthermore, the water-swellable polyurethane-based resin does not hinder the flame retardancy as compared with other resins, and is easy to use for fabrics that require flame retardancy.

  The water swelling ratio of the water-swellable polyurethane resin is preferably 150% or more, and more preferably 200% or more. Further, the water swelling rate of the water-swellable polyurethane resin is preferably 500% or less, and more preferably 400% or less. When the water swelling rate is less than 150%, the ink absorbability is lowered, the density and saturation are lowered due to image bleeding and pigment particle aggregation, and it is difficult to obtain a satisfactory image. On the other hand, when the water swelling rate exceeds 500%, the ink receiving layer is poor in water resistance, and particularly when wetted with water, the strength decreases, and scratches may easily occur, or the ink receiving layer may peel off from the substrate.

  Here, in general, the fabric has irregularities on the surface. Therefore, the ink applied to the fabric exhibits a specific bleeding behavior. Therefore, in order to obtain an image with high density and high saturation without impairing the inherent flexibility of the fabric, the film elongation of the resin is preferably 300% or more. The film elongation of the resin is preferably 500% or less. When the film elongation is less than 300%, the flexibility of the fabric is lowered, the flexibility, which is a characteristic of the fabric, is lowered, and creases are likely to occur when bent or folded. On the other hand, when the film elongation exceeds 500%, the influence of the fabric having high flexibility is strongly exerted, and the printer transportability of the fabric is liable to be adversely affected. In this embodiment, the film elongation can be measured by a JIS K-6251 tensile test method.

  Returning to the description of the entire ink receiving layer, it is preferable that in addition to the ink receiving agent, in the ink receiving layer, amorphous silica is appropriately blended in the ink jet recording sheet in order to improve ink absorption. Amorphous silica is excellent in ink absorption speed and inexpensive. Examples of the amorphous silica include wet precipitation silica, gel silica, and dry (gas phase) silica. Among these, amorphous silica is preferably wet gel silica because it has a large specific surface area and high ink receiving ability.

  The ink receiving layer may be used by mixing a cationic resin, a flame retardant, a light resistance improver, an antioxidant, a viscosity modifier, a crosslinking agent, a pH adjuster, etc. in addition to the ink receptor and amorphous silica. Good.

  Examples of the cationic resin include cationic polymer compounds such as polyethyleneimine resin, polyacrylic resin, polyamine resin, polyamide resin, and polyurethane resin. These may be used alone or in combination.

  Any conventionally known flame retardant is used as the flame retardant. Examples of such flame retardants include halogen flame retardants such as hexabromocyclododecane and tetrabromobisphenol A, phosphorus flame retardants such as tributoxyethyl phosphate and ammonium polyphosphate, and inorganic flame retardants such as antimony trioxide and zinc chloride. Examples include flame retardants, other nitrogen-containing compound flame retardants, and silicone flame retardants. These may be used alone or in combination.

  Various light resistance improvers such as benzotriazole, benzophenone, triazine, cyanoacrylate, oxanilide, salicylate, formamidine, carbazide, benzoate, nickel complex, hindered amine, cinnamate, etc. Illustrative examples are light resistance improvers. These may be used alone or in combination.

  Examples of the antioxidant include hindered amines and hindered phenols. These may be used alone or in combination.

  Examples of the viscosity modifier include methyl cellulose, ethyl cellulose and derivatives thereof, glycerins and polyglycerin and polyethylene oxide and polypropylene oxide adducts thereof, and polysaccharides and derivatives thereof. More specifically, examples of the viscosity modifier include glucose, fructose, mannitol, D-sorbit, dextran, xanthan gum, curdlan, cycloamylose, maltitol, and derivatives thereof. These may be used alone or in combination.

  Examples of the crosslinking agent include isocyanate crosslinking agents, carbodiimide crosslinking agents, isothiazoline crosslinking agents, carbodilite crosslinking agents, and the like. These may be used alone or in combination.

  Examples of pH adjusters include acidic adjusters such as malic acid, citric acid, acetic acid, ammonium citrate, and potassium dihydrogen phosphate, and alkaline adjusters such as sodium bicarbonate, sodium carbonate, disodium hydrogen phosphate, and sodium acetate. Etc. are exemplified. These may be used alone or in combination.

  A coating agent is applied to the surface of the fabric to prevent fraying. Therefore, it is preferable to employ a coating method as a method of forming the ink receiving layer on the surface of the fabric. The coating method is a method of coating the fabric surface with a fixable liquid.

  As described above, the ink jet recording sheet according to the present embodiment is manufactured at a lower cost as compared with a case where a high-cost process such as a process of exposing a cut part to a flame or a process of fixing a cut part with a resin is performed. can do. In addition, the obtained ink jet recording sheet is provided with a coating agent having a predetermined glass transition point more than the thickness of the fabric. Therefore, when performing inkjet output, the inkjet recording sheet can prevent poor conveyance due to fraying of the yarn and poor printing due to nozzle clogging.
