Description

  The present invention relates to an improvement in a textile material or leather material printing method using printed paper. Specifically, the printed paper obtained by printing the dye ink on the printing paper obtained by applying a mixed paste composed of a water-soluble synthetic binder, a natural glue and an auxiliary agent to the base paper is pasted on a fiber material or leather material. The present invention relates to an improvement of a paper printing method characterized by performing a dye fixing process in a state.

  As used in this specification, “base paper” refers to base paper used for the production of textile printing paper, “printing paper” refers to base paper to which mixed glue is applied, and “printing paper” refers to dye ink. Means printed textiles.

  As a method for transferring a pattern to a fabric with a dye, a plate-making printing method transfer printing method using inkjet printing or the like is known together with a plate-making printing method printing method. Compared to the plate-making printing method, the plate-free printing method shortens the delivery time because there is no mold manufacturing process, makes it possible to change lots easily and produce small lots, and has a variety of expressions with no restrictions on the number of colors. Yes, the equipment to be used is relatively small and simple, the work space may be small, it can be handled by non-skilled technicians, the amount of colored wastewater is small, and the environmental burden is reduced , Etc. are attracting attention.

  In addition, various improved methods are used to solve problems such as plate-less printing methods, reduction in leveling due to dot spots, reduction in fineness due to dye ink bleeding, and fastness and pattern reproducibility. Are proposed in Patent Literature 1, Patent Literature 2, and the like. For example, the method described in Patent Document 2 uses a paper having a release agent layer (release paper), and applies a mixed paste liquid composed of glue and resin on the release agent layer, and then dries the ink. This is a method in which a layer is formed, dye ink is printed on the ink-receiving layer, dry-transferred to a fabric, a release paper is peeled off, and then the dye transferred on the fabric is fixed by steaming or the like.

However, this method has the following problems.
(A) An expensive release paper is required, resulting in an increase in cost. In addition, the release paper has poor disintegration property, and it is difficult to recycle the recovered paper.
(B) There is a problem in releasability (reproducibility of paper peeling) in the step of transferring the ink receiving layer to the fabric, and there are cases where transfer to 100% fabric is impossible (peeling instability). When the ink receiving layer partially remains on the printed paper, the portion becomes mottled and a defective product is generated.
(C) Since the ink receiving layer is transferred to the fabric, the paste, resin, and excess dye ink in the ink receiving layer flow out to the waste water in the washing step of the fabric after the dye fixing treatment. Therefore, the waste water is contaminated.
(D) Many general-purpose release agents have a low melting point (for example, the melting point of polyethylene laminate release agent is about 110 ° C.). When transfer is performed at a high temperature to improve transferability, the release agent is It melts and adheres to the cloth, and the texture of the cloth becomes hard. Alternatively, the melted release agent causes a part of the ink receiving layer to remain on the release paper and generate defective products.
(E) Due to the low melting point of the release agent, the drying temperature after application of the mixed paste is restricted, and it is difficult to increase the production speed. Therefore, there is a problem in production efficiency.

  Therefore, as a method for solving these problems, printing is performed by printing dye ink on a printing paper obtained by applying a mixed paste composed of a water-soluble synthetic binder, a natural paste and an auxiliary agent to a base paper and drying it. A step of obtaining paper, a step of attaching (temporarily adhering) the printed paper to a fabric or the like (fiber material or leather material), a step of performing a dye fixing process (such as steaming) with the printed paper attached, and Patent Document 3 discloses a textile material or leather material printing method including a step of removing printed paper after fixing treatment. This method is named “Paper Textile Printing Method” in Patent Document 3.

  In the paper printing method, inexpensive paper can be used as the base paper, and it is not necessary to use expensive release paper, can solve the problem of defective products caused by peeling instability, can further reduce drainage load, texture It can be applied at high temperature and high-density dyeing while maintaining the above, and since no release agent is used, there are advantages such as increasing the drying temperature of the mixed paste and improving the coating efficiency, The problems A) to (E) are improved. As a result, it is possible to provide a fine printed pattern with good reproducibility based on excellent economic efficiency and ecology.

  In the paper printing method, it is desired to reduce the amount of the mixed paste applied in order to reduce the raw material costs and to reduce the drainage load. In addition, in order to improve productivity, it is hoped that the coating speed in the coating (applying) process (coater speed) and the printing speed in the process of producing printed paper by printing dye ink (printing process) will be improved. It is rare. However, in the paper printing method described in Patent Document 3, it is difficult to reduce the application amount of the mixed glue or improve the productivity for the reasons described below, and the improvement has been desired.

(F) If the amount of application (coating) of the mixed paste is reduced, problems such as color developability and adhesiveness (stability of application of printed paper) tend to occur.
(G) If the solid content of the mixed paste is lowered (increase the amount of water) to reduce the viscosity in order to improve the coating speed, the amount of coating is reduced, causing problems in adhesion and color development. In addition, shrinkage and wrinkles of the base paper are likely to occur, and uniform coating may be hindered, resulting in defective printed paper.
(H) When the coating speed is increased, drying may be insufficient in the drying process after coating, and a blocking phenomenon may occur in which the front and back of the paper adhere after winding the printed paper.
(I) When the printing speed is increased, the ink is not sufficiently dried, and the printed ink may partially move to the back of the printed paper (color transfer), resulting in a defective product due to color spots.

(J) Furthermore, when printing paper by the paper printing method described in Patent Document 3 is stored in a place with high humidity, the glue may absorb moisture and cause a blocking phenomenon, so that improvement has been desired.

  These lubricants and moisture-proofing agents can be used alone or in a mixture of two or more. Furthermore, various auxiliary agents A can be added as necessary. As auxiliary agents A, polyvinyl alcohol, natural glue, talc, kaolin, calcium carbonate and organic pigments described in Japanese Patent No. 4258891 ( Plastic pigments). Talc, kaolin, calcium carbonate and plastic pigment are used in combination with lubricants and moisture-proofing agents to control the coefficient of friction.

  As a method for applying a lubricant and / or a moisture-proof agent to paper, the above-described method, that is, an emulsion or a mixed solution obtained by dissolving or emulsifying a lubricant, a moisture-proof agent, and an auxiliary agent A added as necessary in a solvent such as water, is used. In addition to the method of applying on the base paper (Claim 4 or 6), the method of impregnating the base paper by immersing the base paper in the emulsion or liquid mixture (Claim 5), the method of applying in the paper making process of the paper, the emulsion or liquid mixture The method of spraying and applying can be mentioned, but is not limited thereto. After applying the emulsion or mixed solution to the base paper, it is dried and then dried on the base paper (when the application is applied by application) or inside the base paper (when the application is applied by impregnation or when applied in the paper making process) Then, a layer composed of a lubricant and / or a moisture-proof agent is formed to become a base paper, and a mixed paste is applied to the base paper. When the lubricant and / or moisture-proofing agent is applied to one side of the base paper, the mixed glue is preferably applied to the other side.

  Note that the application of the lubricant and / or the moisture-proof agent and the application of the mixed paste may be performed simultaneously. For example, a lubricant and / or a moisture-proofing agent may be applied to one of both sides of the paper, and at the same time, a mixed paste may be applied to the other side and dried simultaneously.

  The paper printing method of the present invention is characterized by using a base paper to which a lubricant and / or a moisture-proofing agent is added, but the other is the same as the known paper printing method described in Patent Document 3. That is, a mixed glue composed of a water-soluble synthetic binder, a natural glue and an auxiliary agent is applied to a base paper, dried to obtain a printed paper, and the printed paper on which the dye ink is printed is used as a fiber material. Alternatively, it is applied to a leather material (cloth, etc.) and dyeing treatment such as steaming is performed to fix and develop the dye and to reduce the adhesive force between the printing paper and the fabric, etc. Is carried out in the same manner as a known paper printing method, except that the amount of mixed glue applied can be reduced.

  Therefore, it has the same advantage as the known method. That is, due to the peeling instability in the known transfer printing method, which can solve the problems (A) to (E), and can make a base paper not by expensive release paper but by generally available inexpensive paper. Can solve problems of defective products that occur, can reduce drainage load, can be applied at high temperature while maintaining the texture and can be dyed at high concentration, and does not use a release agent (low melting point), so mixing It is possible to improve the coating efficiency by raising the drying temperature of the paste liquid (for example, the drying temperature after coating can be increased to 150 to 180 ° C. and the coating speed can be increased three times or more).

  As a base material of the base paper used in the paper printing method of the present invention, that is, a paper to which a lubricant and / or a moisture proofing agent is applied, the same paper as the base paper of the known paper printing method can be used. That is, the paper is not particularly limited as long as the paper can be provided with the mixed paste and has strength and flexibility that can be used as printing paper. Therefore, paper other than extremely low wet strength such as tissue and toilet paper can be used, and it is inexpensive because commonly used paper or commercially available normal paper can be used as it is as the base paper. . Although processed paper such as coated paper can be used, it is not necessary to use expensive release paper having a release layer. Therefore, the manufacturing cost can be greatly reduced.

For example, paper made from pulp such as kraft pulp or grind pulp or recycled paper as a raw material, and a paper having a basis weight of 10 g to 100 g / m ² , preferably 20 to 80 g / m ² , etc. Paper is used. From the viewpoint of workability, paper having a thickness of about 0.01 to 0.5 mm is preferable. In particular, inexpensive and strong kraft paper and high-quality paper are preferably used. Commercially available products include bleached or unbleached kraft paper manufactured by Nippon Paper Industries, high quality paper, brands such as silver bamboo, silver candy, and silver from Nippon Daishowa Paperboard Co., Ltd. Examples include bleached kraft paper and unbleached kraft paper, but these are just examples.

  The water-soluble synthetic binder constituting the mixed paste is water-soluble, is polymerized by heating, has a high molecular weight, and has a resin film forming property. Moreover, the adhesive force which adhere | attaches a fiber, leather, and a base paper is produced by heating and pressurizing the film formed on the base paper or in a base paper. On the other hand, it has the property that the adhesive strength is reduced by the dye fixing process (steaming, humidification, or dry heat treatment at high temperature). Therefore, it is possible to form a film with strong adhesive strength in the dry state after heating and pressurizing, and a binder excellent in properties (temporary adhesiveness) in which the adhesive strength is greatly reduced by steaming, humidification, or dry heat treatment at high temperature. Is preferred.

  Examples of the water-soluble synthetic binder include those synthesized mainly by petrochemistry. Further, a binder that does not inhibit dyeing is desired. Specifically, a water-soluble polyvinyl alcohol binder, a water-soluble acrylic binder, a water-soluble urethane binder, a water-soluble urethane-modified ether binder, a water-soluble polyethylene oxide binder, a water-soluble polyamide binder, a water-soluble phenol binder, Water-soluble vinyl acetate binder, water-soluble styrene acrylic acid binder, water-soluble styrene maleic acid binder, water-soluble styrene acrylic maleic acid binder, water-soluble polyester binder, water-soluble polyvinyl acetal binder, water-soluble polyester / urethane Examples thereof include a water-based binder, a water-soluble polyether / urethane-based binder, a water-soluble hot melt adhesive, and the like, and one or a mixture of two or more selected from these can be preferably used.

  Among them, water-soluble polyvinyl alcohol binders, water-soluble acrylic binders, water-soluble polyester binders, water-soluble polyether / urethane binders, and water-soluble hot melt adhesives are excellent in water-solubility and temporary adhesion, and are dyed. This is preferable because of the small inhibition. Examples of the water-soluble hot melt adhesive include alkaline water-soluble hot melt adhesives of maleic acid alternating copolymers, water sensitive hot melt adhesives, polyvinyl alcohol hot melt adhesives, and the like.

  The natural sizing agent constituting the mixed paste is obtained by processing the raw material of the sizing agent produced in nature as it is or physically or chemically. Natural glues show adhesive strength, but unlike water-soluble synthetic binders, they do not polymerize or increase in adhesive strength even when heated. On the other hand, it can be removed by steaming or dry heat treatment, and is preferably hydrophilic. In addition, the compatibility with water-soluble synthetic binders and dye inks is high, and the property of uniformly absorbing and holding dye inks is required.

  Natural glues are classified into animal glues, plant glues, and mineral glues. Examples of the animal paste include gelatin extracted from collagen contained in animal skin and bone. Examples of the plant paste include CMC that uses starch or cellulose as a starting material. Examples of the mineral paste include clay collected from clay minerals. More specifically, natural gum paste (etherified tamarind gum, etherified locust bean gum, etherified guar gum, acacia arabic gum, etc.), fibrin-derived glue (carboxymethylcellulose, etherified carboxymethylcellulose, hydroxyethylcellulose, etc.), Polysaccharides (starch, glycogen, dextrin, amylose, hyaluronic acid, kudzu, konjac, potato starch, etherified starch, esterified starch, etc.), seaweed (sodium alginate, agar, etc.), mineral paste (bentonite, porcelain clay, silicic acid) Aluminum and its derivatives, silica, diatomaceous earth, clay, kaolin, acid clay, etc.), animal glue (casein, gelatin, egg protein, etc.), and one or a mixture of two or more selected from these Can be preferably used.

  Among them, natural gum paste, cellulose derivatives such as CMC, starch derivatives such as etherified starch, seaweed such as sodium alginate, mineral glue such as silicon dioxide, aluminum silicate, clay, and animal glue are preferable. It is a paste.

  The blending ratio of the water-soluble synthetic binder and the natural paste is preferably in the range of water-soluble synthetic binder: natural paste = 95: 5 to 20:80 (mass ratio) in terms of solid content. When the blending ratio of the water-soluble synthetic binder is less than 20% by mass or more than 95% by mass of the total mass of the water-soluble synthetic binder and the natural paste (when the natural paste is less than 5% by mass), There are problems such as paper peelability (easiness of peeling of printed paper), dyeing property, leveling property, adhesive strength between paper and fabric, and fineness. Tend to occur.

  The auxiliary agent constituting the mixed paste is added for improving various physical properties of the mixed paste, promoting dyeing properties, and the like. Examples of auxiliary agents include surfactants, thickeners, moisturizers, pH adjusters, alkali agents, thickening agents, preservatives, antifungal agents, degassing agents, antifoaming agents, and reducing agents. One or two or more selected from the auxiliaries exemplified herein can be used.

  In the case of an anionic surfactant added as a surface tension reducing agent or a penetrating agent in the mixed paste, 0.2 to 5% by mass, for improving the adhesion and dyeing power to fabrics of printing paper In the case of polyhydric alcohols such as polyethylene glycol, glycerin, thiodiglycol and diethylene glycol, urea, thiourea, dicyandiamide, etc., 1-15% by mass, increase the viscosity of the mixed paste In the case of an acrylic acid synthetic paste which is a thickener for facilitating the application to the base paper, 0 to 3% by mass of antiseptic, antifungal agent, antifoaming agent, degassing agent, anti-reducing agent In the case of 0.1 to 5% by mass, in the case of an alkaline agent such as soda ash, sodium bicarbonate, sodium oxalate, sodium acetate, etc. added when using a reactive dye, 1 to 15% by mass, when using a disperse dye or an acid dye Added to Acetate, 0.1 to 3 wt% in the case of PH adjusting agents such as ammonium sulfate or phosphate monobasic sodium, favorable results when blended.

  The mixed paste used in the paper printing method of the present invention is a hydrophilic mixture in which a water-soluble synthetic binder, a natural paste and an auxiliary are blended. By applying the mixed paste (hydrophilic mixture) or a solution thereof (mixed paste solution) to the base paper and drying, an improved printing paper used in the present invention can be obtained.

  After applying mixed glue to the base paper to which a mixture of lubricant or moisture proofing agent and auxiliary agent has been applied in advance, or applying lubricant and / or moisture proofing agent and mixed glue simultaneously on both sides one side at a time and then drying. As a result, a layer composed of the mixed paste and the lubricant or moisture-proofing agent is formed on the base paper or inside the base paper. This layer is a multi-component glue layer that contains a mixture of a water-soluble synthetic binder and a natural glue, and may contain various auxiliaries. This layer functions as an ink receiving layer for holding the dye ink, and when the printed paper is in close contact with the fabric or the like and is heated and pressurized, it temporarily bonds the printed paper strongly to the fibers of the fabric or the like. It is also a drug layer.

As described above, the mixed paste has a function as an ink receiving layer, a function as an adhesive layer, and a property that the adhesive strength is reduced and easily removed at the final stage of the dye fixing process by steaming or the like. Specifically, the following conditions must be satisfied.
1. Good compatibility with dye ink and does not interfere with dyeing on the fiber. That is, it is a mixed paste that gives excellent reproducibility of density and hue after dyeing.
2. By heating and pressurizing, fibers (fiber materials, leather materials) and paper can be temporarily strongly bonded. That is, in a dry state after applying pressure and applying heat, the fiber-paper has an adhesive force that strongly bonds temporarily (until the final stage of the dye fixing process).
3. The ink absorbency is good, the apparent ink drying property is good, and the fineness of the color pattern is also excellent. That is, the ink receptivity is large.
4). Adhesive strength is easily reduced by a dye fixing process such as steaming. That is, it is a mixed paste that can easily lose its adhesive strength when moisture or moisture is applied and can easily peel the printed paper from the fiber material or leather material.
5. It can be removed from the colored fiber material or leather material by washing with water after dye fixation, soaping, or the like. That is, it is a mixed paste having a high water solubility even after heating.

  The method for applying the mixed paste to the base paper is not particularly limited, but a method of applying, spraying, or base paper a mixed paste solution obtained by dissolving the above-mentioned components constituting the mixed paste in a solvent such as water. And the like can be mentioned by immersing in a mixed paste solution. After applying the mixed paste solution to the base paper, it is dried to dry the layer (ink) on the base paper (if the application is applied) or inside the base paper (if the application is absorbed) A receiving layer / adhesive layer) is formed, and a printed paper is obtained.

  Examples of the device for applying the mixed paste include a comma coater, a gravure coater, a reverse coater, an air knife coater, a jet coater, and an impregnation device, but these are only examples.

  The application amount of the mixed glue is related to the cost of the printing paper and the strength and color developability when the binders adhere to the fiber material. Therefore, when this application is performed by coating using a coating machine, it is important to control the amount of adhesion, such as adjusting the coater clearance and winding speed. Also, depending on the types of the mixed paste and the base paper, the shrinkage and swelling of the paper may occur during the application of the mixed paste, and wrinkles may occur, making it difficult to uniformly apply the paste to the base paper. However, when the mixed paste is applied using the base paper to which the lubricant and / or moisture proofing agent used in the present invention is applied, shrinkage of the base paper and generation of wrinkles during coating can be suppressed, and uniform coating becomes possible. This brings about an effect of reducing the occurrence of defective printing paper.

In the known paper printing method described in Patent Document 3, the amount of the mixed glue applied was 10 to 100 g / m ² in terms of dryness. For example, Example 1, 38 g / ^{m 2,} Example 3, 40 g / ^{m 2,} Example 4, 35 g / ^{m 2,} Example 6 In 38 g / ^{m 2,} an embodiment 7 in 40 g / ^{m 2,} giving It is shown that the amount is preferably 35-40 g / m ² . And when the application amount of the mixed paste is small, the adhesiveness and color developability are lowered.

However, in the present invention, even if the applied amount is 10 to 20 g / m ² , adhesiveness and color developability equal to or higher than those in the case of 35 to 40 g / m ² in a known paper printing method can be obtained. Therefore, the application amount of the mixed paste can be greatly reduced, and as a result, excellent effects such as reduction of raw material costs, reduction of drainage load, and improvement of productivity in the coating process can be achieved.

  A dyed ink is printed on the printing paper to which the lubricant or moisture proofing agent and the mixed paste are applied as described above, based on the printing pattern, and then dried to produce a printed paper. The above-mentioned mixed glue is mainly applied to one surface side of textile printing paper, and when a lubricant and / or a moisture-proofing agent is applied to the opposite side or inside the base paper, the dye ink is applied to the side to which the mixed glue is applied. Is printed. As a printing method, a method by ink jet printing is preferable, but other methods such as gravure printing, flexographic printing, screen printing and the like can also be mentioned, and printing can be performed by the same methods and conditions as in known transfer textile printing. I can do it.

  The dye ink used here is obtained by dissolving or dispersing a dye in a dye solubilizer or dispersant. The type of the dye is selected from reactive dyes, direct dyes, acid dyes, metal complex dyes, disperse dyes, cationic dyes and the like according to the types of fibers constituting the fiber material or leather material. When the disperse dye is converted into an ink, it is desirable that the average particle diameter of the dye is atomized to about 0.1 μm by using 0.1 to 0.3 mm zirconium beads.

  Examples of the dye dissolving agent include water, thiodiglycol, polyethylene glycol, glycerin, ethylene glycol, and ε-caprolactam. In addition, drying ink, surface tension adjuster, viscosity adjuster, pH adjuster, preservative, antifungal agent, sequestering agent, antifoaming agent, deaerator, etc. are added to dye ink as necessary Is done. A dye ink is used in which these components are mixed and a minute amount of insoluble matter is filtered and degassed with a membrane filter of 1 micron or less.

  As a method of printing the dye ink on the textile paper, a method of ink-jet printing using an aqueous dye ink is preferable, but other printing methods such as gravure printing and flexographic printing are also applicable. The water-based dye ink is an ink in which a dye is dissolved or dispersed with water or a solvent that dissolves in water as a main component. Adjust the ink viscosity with a thickener or the like as necessary. In the present invention, the dye ink is an aqueous dye ink, and the printing is preferably performed by a printing method such as inkjet printing or gravure printing.

  The printed paper produced as described above is brought into close contact with the textile material or leather material to be printed, and is heated and pressurized. By heating and pressing, the printed paper and the fiber material or leather material are bonded. The heating and pressurizing conditions can be the same as those for ordinary transfer printing, but it is preferable to set the pressure slightly higher.

  After heating and pressurizing, the dye fixing process is performed by steaming or the like in a state where the printed paper is in close contact. By the fixing treatment, the adhesive force of the ink receiving layer / adhesive layer is reduced, and the printed paper is easily peeled and removed.

  As the dye fixing treatment, there can be employed a method of heating in a state where humidification, moisture application, or the like is performed in addition to heating by steam which is usually performed in printing using a reactive dye or the like. As the conditions for the dye fixing process by steaming, the same conditions as the dye fixing conditions employed in the normal direct printing method can be used as they are. For example, when the dye is a reactive dye, steaming is performed by a one-phase steam fixing method at 100 to 105 ° C. for 5 to 20 minutes, and when the ink receiving layer does not contain an alkali, a two-phase method (for example, a cold fix method) The same conditions as the steaming by) can be applied. When the dye is an acid dye, a steaming treatment at 100 to 105 ° C. for 10 to 30 minutes can be performed. When peeling the paper from the dough, it is easy to peel off the paper in a state where moisture and moisture after steaming are applied.

  In the case of printing polyester fibers using a disperse dye, the fixing treatment can be performed by HT steaming or dry heat treatment at 160 to 210 ° C. for 1 to 15 minutes. That is, the printed paper can be peeled by a method of drying and heating after pasting at a high temperature. In this case, after drying and heating (fixing), it can be more easily peeled off by applying a small amount of moisture or moisture.

  The dye fixing process may be performed after heating and pressurization, or may be performed simultaneously with the heating and pressurization. By heating / pressurizing and dye fixing treatment, most of the dye in the dye ink printed on the printing paper is absorbed and dyed on the fiber material or leather material. In addition, the dye fixing process fixes the dye dyed on the fiber material or leather material, and decreases the adhesive force between the printed paper and the fiber material or leather material. Therefore, the printed paper is easily peeled from the fiber material or leather material.

  The dyeing and fixing of the dye to the fiber material or leather material is performed by a treatment process such as steaming, and after the printed paper is peeled off and removed, a normal washing process such as water washing and soaping is performed. A small amount of the mixed paste may be transferred from the printed paper to the fiber material. In this case, the mixed paste is washed and removed in this washing step. Therefore, the mixed paste preferably has a property that can be easily removed by washing. By removing the mixed paste with water, it is possible to obtain a fine and dense printed product having a good fiber texture. In the case of synthetic fibers such as polyester (in the case of disperse dyes), even if the washing step is omitted, it is possible to obtain a fine and dense printed product having a good texture.

  In the case of transfer printing using a release paper, the ink receiving layer and the dye ink are all transferred to the fiber material, so that there is a problem that waste water contamination due to the unfixed excess dye and paste is large. However, in the paper printing method, the dyed paper (excess dye) and most of the mixed paste remain on the printed paper peeled from the fiber material and the like, while the mixed paste is applied to the fiber material and the like. Since there is almost no adhesion, the drainage load during cleaning is greatly reduced. The method of the present invention can further reduce the application amount of the mixed paste further than the known paper printing method, and therefore can further reduce the drainage load, which is a more ecological processing method.

  The fiber material to which the paper printing method of the present invention is applied includes both natural fiber materials and synthetic fiber materials. Examples of natural fiber materials include cellulosic fiber materials such as cotton, hemp, lyocell, rayon and acetate, and protein fiber materials such as silk, wool and animal hair. Examples of synthetic fiber materials include polyamide fibers (nylon), fibers called vinylon, polyester, polyacryl, and the like.

  Examples of the leather material to which the present invention is applied include animal leather, for example, natural leather such as cow, buffalo, pig, horse, sheep, goat, kangaroo, deer, rabbit, rabbit, rabbit, camel, etc. The thing dried through the process can be mentioned. The paper printing method of the present invention is applied to single, blended, blended or interwoven products of these fiber materials such as woven fabrics, knitted fabrics, nonwoven fabrics, and leathers. Furthermore, a composite fiber may be used.

  If necessary, it may be used for paper printing after pretreatment of fiber materials with agents that affect dye dyeing or agents that are effective in promoting dyeing. There is no feature of the present invention.
