Description
本発明は、転写捺染印刷に使用する捺染印刷用転写紙に関する。特に本発明の捺染印刷用転写紙は、繊維材料又は皮革材料などの被印刷物への転写捺染印刷に好適である。 The present invention relates to a transfer paper for textile printing used for textile printing. In particular, the transfer paper for textile printing of the present invention is suitable for textile transfer printing on textiles or leather materials.
布帛に染料で図柄を堅牢・精細に描く方法として、捺染印刷法が知られている。捺染印刷法は、製版を使用する製版プリント方式と製版を使用しない無製版プリント方式に大別することができる。 2. Description of the Related Art Textile printing is known as a method for drawing patterns on fabrics with dyes in a robust and precise manner. Textile printing methods can be broadly classified into plate-making printing methods that use plate-making and plateless printing methods that do not use plate-making.
製版プリント方式による捺染印刷としては、スクリーン捺染、ローラー捺染、ロータリースクリーン捺染、グラビア印刷又はこれらのプリント技法を用いた方法等が知られており、工業的に実施されている。しかし、製版プリント方式の捺染印刷では版を製作するために色数に制約があり、特に三原色色分解型枠によるプリントでは、多色感を表現できるものの、三原色組成の色相・濃度を整えることが困難、多重層を形成するためプリント加工の再現性を欠きやすい、等の問題がある。加えて、小ロット生産では彫刻作製（製版）費用が高価となり、更にプリント加工時、色糊を加工に必要な量より余剰に調整する必要がある等、資材面での無駄や損失が大きいとの問題点が指摘されている。 Screen printing, roller printing, rotary screen printing, gravure printing, a method using these printing techniques, and the like are known as print printing by the plate-making printing method, and are industrially practiced. However, in the printing process of the plate-making printing method, the number of colors is limited in order to produce a printing plate.In particular, in the case of printing with a three-primary-color separation mold, a multicolor feeling can be expressed, but it is necessary to adjust the hue and density of the three-primary-color composition. There are problems such as difficulty in reproducibility of print processing due to difficulty in forming multiple layers. In addition, in small-lot production, engraving manufacturing (plate making) costs are expensive, and when printing, it is necessary to adjust the color glue more than necessary for processing. Problems have been pointed out.
これらの問題点を解決する新たな捺染法として、無製版プリント方式による捺染印刷が脚光を浴びている。無製版プリント方式では、コンピュータなどで画像処理を行い、例えば、水性の染料インクを用いてインクジェットプリントで被印刷物に図柄をプリントする。そして、この無製版プリント方式の捺染印刷法として、被印刷物に直接プリントするダイレクトプリント方式と、転写紙などにいったん図柄をプリントしてから被印刷物へ図柄を転写する転写プリント方式が提案されている。 As a new printing method for solving these problems, printing using a plateless printing method has been spotlighted. In the plateless printing method, image processing is performed by a computer or the like, and a pattern is printed on a printing material by, for example, inkjet printing using an aqueous dye ink. As a textile printing method of the plateless printing method, a direct printing method of directly printing on a printing material and a transfer printing method of printing a design on a transfer paper and then transferring the design to the printing material have been proposed. .
インクジェットプリントなどを利用したダイレクトプリント方式では、インクジェットインクの滲みを防止するための前処理を施した布帛へ、図柄を直接プリントする。しかしながら、この方法では、滲みを防止するための前処理工程が必要となり、また、インクジェットプリンターによって生地や転写用紙に水性染料インクを小ドットプリントした場合、ドット斑による均捺性を欠くとか、染料インクが滲み出して画像の精細性を失う等の問題点が指摘されている。 In the direct printing method using inkjet printing or the like, a design is directly printed on a fabric that has been subjected to a pretreatment for preventing bleeding of inkjet ink. However, in this method, a pretreatment step for preventing bleeding is required, and when a small dot print of an aqueous dye ink is applied to a fabric or transfer paper by an inkjet printer, lack of uniformity due to dot spots or dye Problems have been pointed out, such as bleeding of ink and losing the definition of an image.
これらの問題点を解決する方法として、転写プリント方式の転写捺染印刷が提案されている。転写捺染印刷では転写紙を用いて転写捺染をするが、転写紙としては、基材となる原紙上に、水溶性ワニス又は溶剤型ワニスなどを含む離型剤層を設け（離型紙）、この離型剤層上に、水溶性糊剤を含む糊層を形成させたものが知られており、その他にも、特殊な多層構造の転写紙が知られている。このような転写紙は、転写紙の糊層にインクジェットプリントなどでインクを糊層中に均一に保持させてから、この転写紙を被印刷物と接触させて転写捺染を行い、図柄を被印刷物に印刷する。 As a method for solving these problems, transfer printing by transfer printing has been proposed. In transfer printing, transfer printing is performed using transfer paper. As the transfer paper, a release agent layer containing a water-soluble varnish or a solvent-type varnish is provided on a base paper as a base material (release paper). There is known one in which a glue layer containing a water-soluble glue is formed on a release agent layer, and in addition, transfer paper having a special multilayer structure is known. In such transfer paper, the ink is uniformly held in the paste layer by ink jet printing or the like on the paste layer of the transfer paper, and then the transfer paper is brought into contact with the printing material to perform transfer printing, and the pattern is printed on the printing material. Print.
これまで転写捺染印刷法として、湿式転写法や乾式転写法などの種々の方法が提案されている。
例えば、熱で昇華する分散染料を用いた昇華転写法（乾式転写捺染法）が知られている。この方法では、昇華性インクをプリントした転写紙を被印刷物に接触させ、昇華により図柄を定着させる。しかし、昇華転写法は、昇華というプロセスが必要で、その適用は昇華性分散染料が染着性を有するポリエステルに限定される上、昇華性インクの使用が必要となり、また、昇華により染色するため高精細な画像が得られにくく、熱安定性が悪く洗濯により色落ちしやすいなど印刷の堅牢度も低い。
Various methods such as a wet transfer method and a dry transfer method have been proposed as transfer printing methods.
For example, a sublimation transfer method (dry transfer printing method) using a disperse dye sublimated by heat is known. In this method, a transfer paper on which a sublimable ink is printed is brought into contact with a printing material, and a design is fixed by sublimation. However, the sublimation transfer method requires a process called sublimation, and its application is limited to a polyester having a sublimable disperse dye having a dyeing property, and further requires the use of a sublimable ink, and for dyeing by sublimation. It is difficult to obtain a high-definition image, has poor thermal stability, and is easy to discolor due to washing.
また、セルロース系繊維又は蛋白質系繊維から成る布帛を水で湿らせ、転写紙と合わせ強く圧着して染料を転写捺染する湿式転写法（特許文献１および特許文献２など）が提案されている。しかし、湿式転写法は、水で湿らせる工程が必要となるため、図柄の精細性と再現性に欠けるという問題が生じやすい。 In addition, a wet transfer method (Patent Document 1 and Patent Document 2, etc.) has been proposed in which a cloth made of a cellulose-based fiber or a protein-based fiber is wetted with water, combined with transfer paper and strongly pressed to transfer and print a dye. However, the wet transfer method requires a step of moistening with water, and thus tends to cause a problem of lack of definition and reproducibility of the pattern.
さらに、特許文献３（特許第４０５８４７０号公報）又は特許文献４（特開平０６−２７０５９６号公報）には、布帛上に乾式転写された染料をスチーミング等で固着処理する方法が開示されている。この方法では、離型剤層を設けた基紙（離型紙）上に混合糊層（インク受容層）を有する転写紙に染料インクをプリントし、それを布帛へ乾式転写して、離型紙を剥離した後、布帛上へ乾式転写された染料をスチーミング等で固着させる。 Further, Patent Document 3 (Japanese Patent No. 4058470) or Patent Document 4 (Japanese Patent Application Laid-Open No. 06-270596) discloses a method of fixing a dye which has been dry-transferred onto a fabric by steaming or the like. . In this method, a dye ink is printed on a transfer paper having a mixed adhesive layer (ink-receiving layer) on a base paper (release paper) provided with a release agent layer, and the dye ink is dry-transferred to a fabric, thereby releasing the release paper. After peeling, the dye that has been dry-transferred onto the fabric is fixed by steaming or the like.
しかし、この方法で用いられる離型紙は、その製造においてコストが高い離型剤を使用すること、および、その製造効率が低いことに起因して、極めて高価であり、一般的な原紙の数倍（５〜１０倍）の製造原価になる。すなわち、離型剤の融点は一般的に低いので、離型剤層の上に糊層（インキ受容層）を設ける際、混合糊液を塗工した後の乾燥温度を上げることができず、乾燥時間が長くなり生産効率が非常に悪くなる。例えば、ポリエチレンラミネート離型剤の融点は約１１０℃であるため、乾燥温度を１１０℃以上に上げることはできず、生産能力（速度）を上げることは困難であった。また、従来の転写紙は、その取り扱いも容易でなく、転写工場の湿度や、転写紙の保管条件又は乾式転写条件が不適切であると、インク受容層を１００％転写して離型紙のみをきれいに剥離できない場合があり、そのような場合は不良品の発生をもたらし、紙のリサイクル使用も困難となる。さらに、少量多品種生産に対応するためには、転写紙が細切れ状態になるため、紙を貼り合わせてリサイクル使用することは事実上困難である。 However, the release paper used in this method is extremely expensive due to the use of a high-cost release agent in its production and its low production efficiency, and is several times larger than that of general base paper. (5 to 10 times) production cost. That is, since the melting point of the release agent is generally low, when providing a paste layer (ink receiving layer) on the release agent layer, the drying temperature after applying the mixed paste liquid cannot be increased, The drying time becomes longer and the production efficiency becomes very poor. For example, since the melting point of the polyethylene laminate release agent is about 110 ° C., the drying temperature cannot be increased to 110 ° C. or higher, and it has been difficult to increase the production capacity (speed). Also, conventional transfer paper is not easy to handle, and if the humidity of the transfer factory, storage conditions of the transfer paper or dry transfer conditions are inappropriate, 100% of the ink receiving layer is transferred and only the release paper is used. In some cases, it cannot be peeled cleanly, and in such a case, defective products are generated, and it is difficult to recycle the paper. Further, in order to cope with small-quantity multi-product production, the transfer paper is cut into pieces, so that it is practically difficult to bond and recycle the paper.
すなわち、この方法には、次に示すような問題点がある。
（Ａ）高価な離型紙が必要である。したがって、コストアップになる。
（Ｂ）インク受容層を布帛に転写する工程での剥離性（紙の剥離の再現性）に難しさがあり、インク受容層を１００％布帛へ転写できない場合がある（剥離不安定性）。部分的にインク受容層が転写紙に残ると、その部分が斑染めになり不良品が発生する。
（Ｃ）インク受容層は布帛へ（望ましくは１００％）移されるので、染料固着処理後の布帛の洗浄工程で、使用済みの糊と樹脂は全量排水へ流れ出し、余剰染料インクも排水に流れ出すので、排水を汚染する。
（Ｄ）汎用の離型剤は融点が低いものが多く、転写性を向上するために高温、例えば１５０℃以上で転写すると、離型剤を構成する樹脂がメルトして布帛へ付着し、洗浄工程では付着した樹脂の除去ができないため、布帛の風合いが硬くなる。またはメルトした樹脂がインク受容層の一部を紙に接着・残留させ、不良品を発生させる。
（Ｅ）生産効率上の問題もある。例えば、離型剤の融点が低いことにより、混合糊液塗工後の乾燥温度が制約され、生産速度を上げることが困難となる。
That is, this method has the following problems.
(A) Expensive release paper is required. Therefore, the cost increases.
(B) There is a difficulty in the releasability (reproducibility of peeling of the paper) in the step of transferring the ink receiving layer to the fabric, and the ink receiving layer may not be able to be transferred to 100% fabric (peeling instability). If the ink receiving layer partially remains on the transfer paper, that portion becomes spot-dyed and defective products are generated.
(C) Since the ink receiving layer is transferred to the fabric (preferably 100%), in the washing process of the fabric after the dye fixing treatment, all the used paste and resin flow out to the wastewater, and the excess dye ink also flows out to the wastewater. Polluting wastewater.
(D) Many of the general-purpose release agents have a low melting point, and when transferred at a high temperature, for example, 150 ° C. or more, in order to improve transferability, the resin constituting the release agent melts and adheres to the cloth, and is washed. Since the adhered resin cannot be removed in the process, the texture of the fabric becomes hard. Alternatively, the melted resin causes a part of the ink receiving layer to adhere to and remain on the paper, resulting in defective products.
(E) There is also a problem in production efficiency. For example, when the melting point of the release agent is low, the drying temperature after the application of the mixed size liquid is restricted, and it is difficult to increase the production speed.
このような課題に対処すべく、特許文献５では、スチーミングなどのインク固着処理によって接着力が低下するバインダーを転写紙の糊層（インク受容層）に用いることによって、転写紙に離型剤層を設けずに、優れた転写捺染印刷を行うことが提案されている。 In order to cope with such a problem, Patent Document 5 discloses that a release agent is applied to a transfer paper by using a binder whose adhesive strength is reduced by an ink fixing process such as steaming for a paste layer (ink receiving layer) of the transfer paper. It has been proposed to perform excellent transfer printing without providing a layer.
本発明者らは、捺染紙を被印刷物に密着させたままスチーミングなどの染料固着処理を行う転写捺染印刷に関して検討を行い、捺染印刷用転写用紙の糊層（インキ受容層）の組成を工夫することによって、融点の低い離型剤を使用せずに、優れた捺染印刷特性を有する捺染印刷用転写紙を開発することに成功した（特許文献５）。 The present inventors have studied transfer printing in which a dye fixing process such as steaming is performed while the printing paper is kept in close contact with the printing material, and devised the composition of the adhesive layer (ink receiving layer) of the transfer paper for printing printing. As a result, a transfer paper for textile printing having excellent textile printing properties was successfully developed without using a release agent having a low melting point (Patent Document 5).
本発明では、捺染紙を被印刷物に密着させたまま染料固着処理を行う転写捺染印刷における優れた転写紙を提供すること目的とする。具体的には、転写捺染印刷用の転写紙として、繊維材料又は皮革材料などの被印刷物に対して、風合い、精細性、堅牢性、発色性等の捺染性能に優れるとともに、上記の問題点（Ａ）〜（Ｅ）等を解決し、資材コストの削減、加工の再現性と品質の向上、排水負荷のさらなる削減、生産効率の向上を図ることができる、エコロジカルかつエコノミカルな捺染印刷用転写紙が望まれており、本発明においてもそのような転写紙を提供することを課題とする。 SUMMARY OF THE INVENTION It is an object of the present invention to provide an excellent transfer paper in transfer printing, in which a dye fixing treatment is performed while the printing paper is kept in close contact with a printing material. More specifically, as a transfer paper for transfer printing, it has excellent printing performance such as texture, fineness, fastness, color development, and the like with respect to an object to be printed such as a fiber material or a leather material. Ecological and economical transfer for textile printing that can solve A) to (E) and reduce material costs, improve processing reproducibility and quality, further reduce drainage load, and improve production efficiency. Paper is desired, and it is an object of the present invention to provide such a transfer paper.
本発明らは、被印刷物に捺染紙を密着させたままで染料の固着処理を行う転写捺染印刷に関して、それに用いる転写紙を鋭意検討したところ、特定の塗工方式で原紙上に塗工して糊層（インキ受容層）を設け、さらに、特に透気抵抗度を８００００秒以下とすることによってさらに優れた捺染印刷用転写紙が得られることを見出した。 The present inventors have studied the transfer paper used for the transfer printing in which the dye is fixed while the printing paper is kept in close contact with the printing material.

本発明は、捺染紙を被印刷物に貼り付けた状態で、染料の固着処理を行うことを特徴とする転写捺染印刷（本明細書においては、「ペーパー捺染法」ともいう）に関する。
本発明において転写捺染印刷とは、紙などの媒体を介して図柄を転写させて捺染印刷することをいい、「捺染印刷用転写紙」とは、かかる転写捺染印刷において図柄を転写させるために用いられる紙をいい、原紙層と糊層（インク受容層）を備える。また、本発明において「捺染紙」とは、染料インクが付与された捺染印刷用転写紙を意味する。 本発明においては、捺染印刷用転写紙を用いて、以下の方法によって捺染印刷を行うことができる。すなわち、原紙と原紙上に非接触方式により設けられた糊層とを備え、転写紙上に、染色インクをプリントして捺染紙を得て、その捺染紙を被印刷物に密着させてから、被印刷物に捺染紙を密着させたまま染料を固着させることによって、被印刷物に捺染印刷を行うことができる。
The present invention relates to transfer printing (hereinafter also referred to as "paper printing"), in which a dye fixing process is performed in a state where a printing paper is attached to a printing material.
In the present invention, transfer printing refers to transferring a pattern through a medium such as paper to perform printing, and `` transfer paper for printing printing '' is used to transfer a pattern in such transfer printing. Paper, which comprises a base paper layer and a glue layer (ink receiving layer). In the present invention, “textile paper” means a transfer paper for textile print to which a dye ink has been applied. In the present invention, textile printing can be performed by using the transfer paper for textile printing by the following method. That is, a base paper and a glue layer provided on the base paper in a non-contact manner are provided, a dyeing ink is printed on a transfer paper to obtain a printing paper, and the printing paper is brought into close contact with the printing material. By fixing the dye while keeping the printing paper in close contact with the printing paper, the printing printing can be performed on the printing substrate.
捺染印刷用転写紙
本発明の捺染印刷用転写紙は、原紙と原紙上に設けられた糊層とを備えている。原紙の透気抵抗度が８００００秒以下である。本発明者は、被印刷物に捺染紙を密着させたままで染料の固着処理を行う転写捺染印刷について鋭意検討を行ったところ、転写紙の透気抵抗性が転写捺染印刷の質に大きな影響を及ぼすことを見出し、さらに、透気抵抗度を国際公開ＷＯ２０１１／０５５８１７（特許文献５）などの従来品よりも低くすることによって優れた捺染印刷用転写紙が得られることを見出した。すなわち、透気抵抗度が８００００秒より高くなると、スチーミングなどによる染料の固着処理の際、熱が伝わりにくくなるためか、染料の染着が十分になされにくくなる一方、本発明の範囲内であれば、染料の固着処理を効率的に行うことができ、繊細な図柄などを捺染印刷することができる。スチーミングなどによる染料の固着処理をより効率的に行うため、捺染印刷用転写紙の透気抵抗度は、６００００秒以下であるとより好ましく、５００００秒以下であるとさらに好ましい。また、透気抵抗度の下限は特にないが、例えば、捺染印刷用転写紙の透気抵抗度が１００秒程度とすることも可能である。本発明において透気抵抗度の測定は、ＪＩＳ Ｐ ８１１７に記載の方法に従って行う。
The transfer paper for textile printing The transfer paper for textile printing of the present invention includes a base paper and an adhesive layer provided on the base paper. The air permeability resistance of the base paper is 80000 seconds or less. The present inventor has conducted intensive studies on transfer printing which performs dye fixing while keeping the printing paper in close contact with the printing material. Further, they have found that an excellent transfer paper for textile printing can be obtained by lowering the degree of air permeation resistance as compared with a conventional product such as WO2011 / 055817 (Patent Document 5). That is, when the air resistance is higher than 80,000 seconds, during the fixing treatment of the dye by steaming or the like, it is difficult to conduct heat, or it is difficult for the dye to be sufficiently dyed, but within the scope of the present invention. If it is, the fixing treatment of the dye can be performed efficiently, and a delicate pattern or the like can be printed. In order to more efficiently perform the fixing treatment of the dye by steaming or the like, the air permeability of the transfer paper for textile printing is preferably 60,000 seconds or less, and more preferably 50,000 seconds or less. Although there is no particular lower limit for the air resistance, the air resistance of the transfer paper for textile printing can be, for example, about 100 seconds. In the present invention, the measurement of the air resistance is performed according to the method described in JIS P8117.
捺染用紙の透気抵抗度を上記範囲に調整する方法としては、原紙の透気抵抗度を一定の範囲とすること、糊層の塗工量を調整すること、糊層の塗工方式を選択すること、糊層に対して表面処理を行うことなどが挙げられる。具体的には、例えば、塗工紙と比較して透気抵抗度が低い非塗工紙（透気抵抗度が１００秒以下の非塗工紙）を原紙として用いることにより、また、糊層の塗工量を少なくしたり、糊層の塗工方式として非接触方式を採用して嵩高な糊層とすることによっても、捺染印刷用転写紙の透気抵抗度を低くすることができる。さらに、例えば、カレンダー処理などの表面処理によって捺染印刷用転写紙の透気抵抗度を上げることも可能である。 As a method of adjusting the air resistance of the printing paper to the above range, the air resistance of the base paper is set to a certain range, the coating amount of the adhesive layer is adjusted, and the coating method of the adhesive layer is selected. And performing a surface treatment on the glue layer. Specifically, for example, by using uncoated paper having a low air resistance as compared with coated paper (non-coated paper having an air resistance of 100 seconds or less) as a base paper, Also, the air permeability resistance of the transfer paper for textile printing can be reduced by reducing the amount of coating or by using a non-contact method as a coating method of the adhesive layer to form a bulky adhesive layer. Further, for example, it is possible to increase the air resistance of the transfer paper for textile printing by a surface treatment such as a calendar treatment.
捺染印刷用転写紙の原紙
本発明の捺染印刷用転写紙に使用される原紙としては、糊層（インク受容層）をその上に塗布することができ、かつ捺染印刷に使用できる強度や柔軟性等を有する紙であれば特に限定されない。混合糊を塗布する際に、しわなどが入らないようにすることや染色品質が良好であることを考慮して、原紙を選択することが好ましい。
Base paper of transfer paper for textile printing As the base paper used for the transfer paper for textile printing of the present invention, an adhesive layer (ink receiving layer) can be applied thereon, and the strength and flexibility that can be used for textile printing The paper is not particularly limited as long as the paper has the following. When applying the mixed paste, it is preferable to select base paper in consideration of preventing wrinkles and the like and good dyeing quality.
本発明の捺染印刷用転写紙に用いる原紙としては、一般的に使用されている紙を用いることができ、紙の強度や柔軟性を考慮して、例えば、坪量が１０〜１００ｇ／ｍ２、より好ましくは坪量が２０〜８０ｇ／ｍ２、さらに好ましくは坪量が４０〜８０ｇ／ｍ２の紙を使用することができる。また、捺染印刷時の作業性などの観点から、転写紙の厚さ（紙厚）は０．０１〜０．５ｍｍ程度の紙が好ましく、０．０５〜０．３ｍｍ程度の紙がより好ましい。原紙の透気抵抗度は特に制限されない。 As the base paper used for the transfer paper for textile printing of the present invention, generally used paper can be used, and in consideration of the strength and flexibility of the paper, for example, the basis weight is 10 to 100 g / m 2. , more preferably a basis weight of 20 to 80 g / m 2, more preferably may be basis weight paper is used for 40 and 80 g / m 2. From the viewpoint of workability during textile printing, the thickness (paper thickness) of the transfer paper is preferably about 0.01 to 0.5 mm, and more preferably about 0.05 to 0.3 mm. The air permeability of the base paper is not particularly limited.
原紙のパルプ配合は特に制限されないが、例えば、クラフトパルプなどの化学パルプ、グラインドパルプなどの機械パルプ、古紙を原料とする古紙パルプなどを好適に使用することができる。また、原紙として非塗工紙を用いても、塗工紙を用いてもよい。原紙には適宜填料を配合することができる。 The pulp composition of the base paper is not particularly limited, but, for example, chemical pulp such as kraft pulp, mechanical pulp such as grind pulp, waste paper pulp using waste paper as a raw material, and the like can be suitably used. In addition, uncoated paper or coated paper may be used as the base paper. A filler can be appropriately added to the base paper.
糊層（インク受容層）
本発明の捺染印刷用転写紙は、上述した原紙上に、インク受容層として糊層を有する。糊層の付着量は特に制限されないが、ドライ換算で５〜７０ｇ／ｍ２が好ましく、１０〜５０ｇ／ｍ２がより好ましく、１５〜３０ｇ／ｍ２としてもよい。糊層の付着量は、捺染用紙のコストやバインダー類が布帛へ接着する際の強度及び発色性に関わってくるので、それらの要素を勘案して適宜選択すればよい。
Glue layer (ink receiving layer)
The transfer paper for textile printing of the present invention has a paste layer as an ink receiving layer on the above-described base paper. Adhesion amount of glue layer is not particularly limited, is preferably 5 to 70 g / m 2 on dry basis, more preferably 10 to 50 g / m 2, may be 15 to 30 g / m 2. The amount of the glue layer to be applied depends on the cost of the printing paper and the strength and color development when the binders are adhered to the fabric, and may be appropriately selected in consideration of these factors.
糊層の付与を塗布装置（コーティング機）での塗布により行う場合は、適宜付着量を管理することが重要である。これまでにさまざまな方式の塗布装置が開発されている。本捺染用紙を製造する際には、エアナイフ方式やカーテン方式、ダイ方式のように、非接触型の塗布方式であれば、種々の塗布方式を使用することができる。 When the glue layer is applied by coating with a coating device (coating machine), it is important to appropriately control the amount of adhesion. Various types of coating apparatuses have been developed so far. In producing the textile printing paper, various coating methods can be used as long as they are non-contact coating methods such as an air knife method, a curtain method, and a die method.
一般に、塗工方式には、塗工装置と被塗工物（本発明では、捺染印刷用転写紙が相当）が接触して塗工液を塗工する接触型の塗工方式と、塗工装置と被塗工物（本発明では、捺染印刷用転写紙が相当）が接触せずに塗工液を塗工する非接触型の塗工方式がある。接触型の塗布装置としては、塗工量を前計量するロールコーターや、後計量する、かき落とし方式のブレード（刃）コーター、ロッドコーター、コンマコーター等がある。非接触型の塗布装置としては、エアナイフコーター、カーテンコーター、ダイコーターなどがある。 In general, the coating method includes a contact type coating method in which a coating apparatus and an object to be coated (corresponding to a transfer paper for textile printing in the present invention) are applied to apply a coating liquid. There is a non-contact type coating system in which a coating liquid is applied without contact between the apparatus and a coating object (in the present invention, a transfer paper for textile printing). Examples of the contact-type coating apparatus include a roll coater for pre-measuring the coating amount, a scraper-type blade (blade) coater for post-measurement, a rod coater, and a comma coater. Examples of the non-contact type coating device include an air knife coater, a curtain coater, and a die coater.
接触型の塗布装置の場合、糊層の表面の平滑性は高くなるが、原紙の凹凸に応じて混合糊層の厚みにムラが生じやすく、画像にもムラができてしまう場合もある。それに対し、非接触型の塗布方式の場合、混合糊層が原紙表面の凹凸に沿って均一に塗布できることから、特にインクジェットプリントした場合の画像の精細性を高くすることができる。従って、本発明においては非接触型の塗布方式によって塗工層を設ける。 In the case of a contact-type coating apparatus, the smoothness of the surface of the glue layer is increased, but the thickness of the mixed glue layer tends to be uneven depending on the unevenness of the base paper, and the image may be uneven. On the other hand, in the case of the non-contact type coating method, since the mixed paste layer can be uniformly applied along the irregularities on the surface of the base paper, it is possible to enhance the definition of an image particularly in the case of inkjet printing. Therefore, in the present invention, the coating layer is provided by a non-contact type coating method.
混合糊を塗布する際の固形分濃度は、塗布方式に合わせて適宜選択できるが、非接触型の塗布方式の場合、５〜６０重量％が好ましい。特に、エアナイフ方式の場合は、１０〜３０重量％、カーテン方式の場合は１０〜３０重量％％、ダイ方式の場合は１０〜５０重量％％が望ましい。 The solid content concentration at the time of applying the mixed paste can be appropriately selected according to the application method. In the case of the non-contact type application method, the solid content is preferably 5 to 60% by weight. In particular, in the case of the air knife system, it is preferably 10 to 30% by weight, in the case of the curtain system, 10 to 30% by weight, and in the case of the die system, it is preferably 10 to 50% by weight.
塗工速度については、特に制限されないが、５ｍ／ｍｉｎ以上であることが好ましく、１０ｍ／ｍｉｎ以上であるとより好ましい。塗工速度が５ｍ／ｍｉｎより低いと、乾燥前に混合糊液が原紙内部に浸透してしまい、インク受容層として有効に寄与する混合糊層が少なくなるため、十分な効果を発現しにくくなる。 The coating speed is not particularly limited, but is preferably 5 m / min or more, more preferably 10 m / min or more. If the coating speed is lower than 5 m / min, the mixed paste liquid permeates into the base paper before drying, and the amount of the mixed paste layer that effectively contributes as an ink receiving layer is reduced, so that it is difficult to exhibit a sufficient effect. .

糊層に用いられる水溶性合成系バインダーは、水溶性であり、加熱により強い被膜形成性を有するものである。また、原紙上または原紙内に形成された糊層は、繊維や皮革などの被印刷物と捺染印刷用転写紙との間を接着させるとともに、染料の固着処理（例えば、スチーミング、加湿、または高温での乾熱処理）により接着力が低下する性質を有するものである。したがって、加熱・加圧した後の乾燥状態で接着力を発揮するとともに、水溶性であるので加湿状態（場合により高温での乾熱処理後の状態）で接着力が弱くなる。 The water-soluble synthetic binder used for the glue layer is water-soluble and has a strong film-forming property when heated. In addition, the adhesive layer formed on or in the base paper adheres between the substrate to be printed such as fiber or leather and the transfer paper for textile printing, and fixes the dye (for example, steaming, humidification, or high temperature). (Dry heat treatment) to reduce the adhesive strength. Therefore, the adhesive strength is exhibited in a dry state after being heated and pressed, and the adhesive strength is weakened in a humidified state (in some cases, after a dry heat treatment at a high temperature) because it is water-soluble.
糊層を構成する水溶性合成系バインダーとしては、下記例示されたものが好ましく使用できるが、このうち、水溶性ホットメルト接着剤としては、マレイン酸交互共重合体のアルカリ水可溶型ホットメルト接着剤、感水性ホットメルト接着剤、ポリビニルアルコール系ホットメルト接着剤等を挙げることができる。 As the water-soluble synthetic binder constituting the glue layer, those exemplified below can be preferably used. Among them, as the water-soluble hot melt adhesive, an alkaline water-soluble hot melt of maleic acid alternating copolymer is used. An adhesive, a water-sensitive hot melt adhesive, a polyvinyl alcohol-based hot melt adhesive, and the like can be given.
この水溶性合成系バインダーとしては、主として石油化学で合成されたものを挙げることができる。また、染着阻害のないバインダーが望まれる。具体的には、水溶性ポリビニルアルコール系バインダー、水溶性アクリル系バインダー、水溶性ウレタン系バインダー、水溶性ウレタン変性エーテル系バインダー、水溶性ポリエチレンオキサイド系バインダー、水溶性ポリアミド系バインダー、水溶性フェノール系バインダー、水溶性酢酸ビニル系バインダー、水溶性スチレンアクリル酸系バインダー、水溶性スチレンマレイン酸系バインダー、水溶性スチレンアクリルマレイン酸系バインダー、水溶性ポリエステル系バインダー、水溶性ポリビニルアセタール系バインダー、水溶性ポリエステル・ウレタン系バインダー、水溶性ポリエーテル・ウレタン系バインダー、水溶性ホットメルト接着剤等を挙げることができ、これらから選ばれた１種または２種以上の混合物が好ましく使用できる。 Examples of the water-soluble synthetic binder include those synthesized mainly by petrochemicals. Also, a binder that does not inhibit dyeing is desired. Specifically, water-soluble polyvinyl alcohol-based binder, water-soluble acrylic-based binder, water-soluble urethane-based binder, water-soluble urethane-modified ether-based binder, water-soluble polyethylene oxide-based binder, water-soluble polyamide-based binder, water-soluble phenol-based binder , Water-soluble vinyl acetate-based binder, water-soluble styrene-acrylic acid-based binder, water-soluble styrene-maleic acid-based binder, water-soluble styrene-acrylic-maleic acid-based binder, water-soluble polyester-based binder, water-soluble polyvinyl acetal-based binder, water-soluble polyester Examples thereof include a urethane-based binder, a water-soluble polyether / urethane-based binder, and a water-soluble hot-melt adhesive, and one or a mixture of two or more selected from these can be preferably used. .

However, it is preferable because it is excellent in the property that the adhesive strength is reduced in a humidified state) and the inhibition of dyeing is small.
また、本発明の転写紙の糊層は、天然系糊剤を含むことが好ましい。天然系糊剤は、天然に産出する糊剤の原料をそのまま又は物理的又は化学的に加工して得られるものである。天然系糊剤は接着力を示すが、水溶性合成系バインダーと異なり、加熱しても接着力が上昇することはない。一方、スチーミングや乾燥加熱処理により除去できるものであり、したがって、親水性であることが望ましい。また、本発明の捺染印刷用転写紙の糊層はインク受容層としても機能するため、染料インクとの相溶性が高く、染料インクを均一に吸収保持する性質を有することが好ましい。 The glue layer of the transfer paper of the present invention preferably contains a natural glue. The natural sizing agent is obtained by directly or physically or chemically processing the raw material of the sizing agent produced in nature. A natural paste shows an adhesive force, but unlike a water-soluble synthetic binder, the adhesive force does not increase even when heated. On the other hand, it can be removed by steaming or drying and heat treatment, and therefore, it is desirable that it be hydrophilic. Further, since the adhesive layer of the transfer paper for textile printing of the present invention also functions as an ink receiving layer, it is preferable that the adhesive layer has high compatibility with the dye ink and has a property of absorbing and holding the dye ink uniformly.

原紙への糊液を塗布した後、乾燥することによって、原紙上（付与が塗布によりなされた場合等。ただし、塗布された場合でも一部は紙内に吸収される）や原紙内（付与が吸収によりなされた場合等）に、糊層が形成される。この層は、水溶性合成系バインダーと天然系糊剤を含むことが好ましく、さらに各種助剤が配合されてもよい。そして、この層は、捺染用紙上にプリントされる染料インクを保持するインク受容層としての機能を有するとともに、捺染紙が布帛等に密着され加熱・加圧されたときには、捺染紙を布帛等の繊維に強く接着する接着剤層としても機能する。 After applying the paste liquid to the base paper, the base paper is dried to allow it to be applied on the base paper (when applied by coating, etc. However, even when applied, a part is absorbed into the paper) or inside the base paper (when the applied A glue layer is formed when absorption is performed. This layer preferably contains a water-soluble synthetic binder and a natural paste, and may further contain various auxiliaries. This layer has a function as an ink receiving layer for holding the dye ink to be printed on the printing paper, and when the printing paper is brought into close contact with a cloth or the like and heated and pressed, the printing paper is converted into a cloth or the like. It also functions as an adhesive layer that strongly adheres to fibers.
転写捺染印刷
本発明の転写捺染印刷においては、上述の転写紙に染料インクがプリントされて捺染紙を得る。捺染印刷用転写紙の糊層上には、染料インクが、捺染の図柄に基づいてプリントされ、その後乾燥することにより捺染紙が作製される。捺染用紙の一方の表面側に糊層が付与されている場合は、該表面側（印刷面）に染料インクがプリントされる。
Transfer Textile Printing In the transfer textile print of the present invention, a dye ink is printed on the above-described transfer paper to obtain a textile print. A dye ink is printed on the paste layer of the transfer paper for textile printing based on the pattern of textile printing, and then dried to produce a textile paper. When the adhesive layer is provided on one surface side of the printing paper, the dye ink is printed on the surface side (printing surface).
ここで用いられる染料インクとしては、具体的には、反応染料、酸性染料、金属錯塩型染料、直接染料、分散染料、カチオン染料等を染料として用いるインクを挙げることができる。染料インクとしては、これらの染料を水等の染料溶解剤に溶解または分散して使用することができる。 Specific examples of the dye ink used here include an ink using a reactive dye, an acid dye, a metal complex type dye, a direct dye, a disperse dye, a cationic dye, or the like as a dye. These dyes can be used by dissolving or dispersing these dyes in a dye dissolving agent such as water.
本発明において、インクジェットプリントに使用する染料インクとしては、染料を染料溶解剤または分散剤等により溶解または分散させたものが使用できる。染料溶解剤としては、例えば水、チオジグリコール、ポリエチレングリコール、グリセリン、エチレングリコール、εカプロラクタムを挙げることができる。染料インクには、さらに、必要に応じて乾燥防止剤、表面張力調整剤、粘度調整剤、ｐＨ調整剤、防腐剤、防黴剤、金属イオン封鎖剤、消泡剤、脱気剤当が添加される。これらの成分を混合して、微量の不純物を１ミクロン以下のメンブレンフィルターでろ過・脱気した染料インクが使用される。 In the present invention, as the dye ink used in the ink jet printing, a dye ink obtained by dissolving or dispersing a dye with a dye dissolving agent or a dispersing agent can be used. Examples of the dye dissolving agent include water, thiodiglycol, polyethylene glycol, glycerin, ethylene glycol, and ε-caprolactam. To the dye ink, if necessary, an anti-drying agent, a surface tension adjusting agent, a viscosity adjusting agent, a pH adjusting agent, a preservative, a fungicide, a metal ion sequestering agent, a defoaming agent, a degassing agent, etc. are added. Is done. A dye ink is used in which these components are mixed, and trace impurities are filtered and degassed by a membrane filter of 1 micron or less.
なお、染料の種類は、布帛を構成する繊維の種類に応じて、反応染料、直接染料、酸性染料、金属錯塩型染料、分散染料、カチオン染料等から選択されるが、分散染料をインク化する場合は、０．１〜０．３ｍｍのジルコニウムビーズを用いて染料の平均粒径を０．１μｍ程度に微粒化することが望ましい。 The type of dye is selected from reactive dyes, direct dyes, acid dyes, metal complex salt type dyes, disperse dyes, cationic dyes, etc., depending on the type of fibers constituting the fabric. In this case, it is desirable to use zirconium beads of 0.1 to 0.3 mm to make the average particle size of the dye finer to about 0.1 μm.
このようにして得られた捺染用紙に、染料インクをプリントし、乾燥して捺染紙を作製する。プリントの方法としては、インクジェットプリントが好ましいが、その他の方法、例えばグラビア印刷、スクリーンプリント等の方法も挙げることができ、公知の転写捺染の場合と同様の方法、条件によりプリントすることができる。染料インクを転写用紙上にプリントする方法としては、インクジェットプリントする方法が好ましい。本発明においては水性染料インクが好ましく、ここで、水性染料インクとは、水又は水に溶解する溶剤を主成分として染料を溶解または分散したインクである。 A dye ink is printed on the printing paper thus obtained and dried to prepare a printing paper. As a printing method, inkjet printing is preferable, but other methods such as gravure printing and screen printing can also be used, and printing can be performed by the same method and conditions as in the case of known transfer printing. As a method of printing the dye ink on the transfer paper, a method of inkjet printing is preferable. In the present invention, a water-based dye ink is preferable. Here, the water-based dye ink is an ink in which a dye is dissolved or dispersed in water or a solvent soluble in water as a main component.
本発明の転写捺染印刷においては、前記のように作製された転写紙を、繊維材料（セルロース系繊維材料、蛋白質系繊維材料、合成繊維材料など）や皮革材料などの被印刷物に密着させる。密着工程において、捺染紙が被印刷物に加熱・加圧などにより密着された後、密着された状態での染料の固着処理が行われる。加熱・加圧の条件は、通常の転写捺染の場合と同様の条件を適用することができ、例えば、ドラムなどにより捺染紙を被印刷物に密着させることができるが、その際の圧力をやや高めに設定するとより好ましい。この、加熱・加圧により、転写紙と繊維材料や皮革材料間が接着される。 In the transfer printing of the present invention, the transfer paper produced as described above is brought into close contact with a printing material such as a fiber material (cellulose fiber material, protein fiber material, synthetic fiber material, etc.) or leather material. In the contacting step, after the printing paper is brought into close contact with the printing material by heating, pressurizing, or the like, the dye is fixed in the contacted state. Heating and pressurizing conditions can be the same as those in normal transfer printing.For example, the printed paper can be brought into close contact with the printing material by a drum or the like, but the pressure at that time is slightly increased. It is more preferable to set to. By this heating and pressing, the transfer paper and the fiber material or the leather material are bonded to each other.
本発明の転写捺染印刷においては、捺染紙を被印刷物に密着させた状態で染料の固着処理を行う。染料の固着処理としては、反応染料等を用いる捺染で通常行われているスチームによる加熱のほか、加湿や水分の付与等を行った状態で加熱する方法等も挙げることができる。また、ポリエステル繊維や合成繊維の捺染の場合は、乾燥加熱する方法も採用できる。このスチームによる加熱や、加湿や水分の付与等を行った状態での加熱により、転写紙の剥離が可能となる。ポリエステル繊維や合成繊維の捺染の場合は、乾燥加熱する方法により転写紙の剥離が可能となる場合もあるが、乾燥加熱（固着）後、水分を付与すると、より容易に剥離することができる。 In the transfer printing according to the present invention, the dye fixing process is performed in a state in which the printing paper is in close contact with the printing material. Examples of the fixing treatment of the dye include, in addition to heating by steam, which is usually performed in printing using a reactive dye or the like, a method in which heating is performed in a state in which humidification, moisture provision, and the like are performed. In the case of printing polyester fibers or synthetic fibers, a method of drying and heating can also be adopted. The transfer paper can be peeled off by the heating with the steam or the heating in a state where the humidification or the provision of the moisture is performed. In the case of printing of polyester fibers or synthetic fibers, the transfer paper may be peeled off by a method of drying and heating, but if moisture is applied after drying and heating (fixation), the transfer paper can be peeled more easily.
捺染紙を布帛等に密着させて行われるスチーミング等による染料の固着処理の条件としては、通常の直接捺染法で採用されている染料のスチーミングによる固着条件と同様な条件をそのまま採用でき、例えば、１００〜２２０℃の蒸気によって捺染紙の非印刷面側からスチーミングを行うことができる。例えば、染料が反応染料の場合は、１相スチーム固着法による、１００〜１０５℃、５〜２０分間のスチーミング、アルカリを含まないインク受容層の場合は、２相法（例えばコールドフィックス法等）によるスチーミングと同様な条件が適用できる。染料が酸性染料の場合は、１００〜１０５℃、１０〜３０分間のスチーミング処理を行うことができる。生地から紙をはがす際、スチーミング後の水分や湿気を付与された状態での紙はがし（紙の剥離）は容易である。染料が分散染料の場合は、１６０〜２２０℃、１〜１５分間のＨＴスチーミングまたは乾熱処理を行う。乾熱処理により紙の剥離は可能になる場合もあるが、乾熱処理後に少量の湿気や水分を付与することにより剥離が容易になる。 As the conditions for fixing the dye by steaming or the like performed by bringing the printed paper into close contact with a cloth or the like, the same conditions as those for fixing the dye by steaming used in a normal direct printing method can be directly employed. For example, steaming can be performed from the non-printing surface side of the printed paper with steam at 100 to 220 ° C. For example, when the dye is a reactive dye, it is steamed at 100 to 105 ° C. for 5 to 20 minutes by a one-phase steam fixing method, and when the dye is an alkali-free ink receiving layer, it is a two-phase method (for example, cold fix method or the like). The same conditions as in the steaming according to (1) can be applied. When the dye is an acid dye, steaming treatment can be performed at 100 to 105 ° C. for 10 to 30 minutes. When peeling the paper from the cloth, it is easy to remove the paper (peeling off the paper) in a state where moisture and moisture are applied after the steaming. When the dye is a disperse dye, HT steaming or dry heat treatment is performed at 160 to 220 ° C. for 1 to 15 minutes. In some cases, the paper can be peeled off by the dry heat treatment, but the peeling becomes easy by adding a small amount of moisture or moisture after the dry heat treatment.
染料の固着処理は、加熱・加圧された後行ってもよいし、前記の加熱・加圧と同時に行っても良い。加熱・加圧及び染料の固着処理により、染料用紙上にプリントされた染料インク中の染料が繊維材料や皮革材料に吸収・染着される。また、染料の固着処理により、繊維材料や皮革材料に染着された染料の固着が行われるとともに、捺染紙と繊維材料や皮革材料間の接着力が低下する。 The fixing treatment of the dye may be performed after heating and pressurizing, or may be performed simultaneously with the above-mentioned heating and pressurizing. The dye in the dye ink printed on the dye paper is absorbed and dyed on the fiber material and the leather material by the heating / pressing and the fixing treatment of the dye. Further, by the dye fixing treatment, the dye dyed on the fiber material or the leather material is fixed, and the adhesive strength between the printing paper and the fiber material or the leather material is reduced.
本発明の転写捺染印刷においては、固着工程の後に捺染紙を被印刷物から剥離させて除去してもよい。前記のように原紙上または原紙中に形成された糊層は、前記の加熱・加圧により接着層としての機能を示すものであるが、一方、布帛等から転写紙の剥離が容易に行えるようにするため、スチーミング等による染料の固着処理工程により、その接着力が低下するものである。すなわち、混合糊の層は、スチーミング等による染料の固着処理工程、または捺染紙を剥離する工程で湿気が付与されることにより、容易に接着力が低下する性質を有することが望ましい。 In the transfer textile printing of the present invention, the textile paper may be peeled off from the substrate after the fixing step and removed. The glue layer formed on the base paper or in the base paper as described above has a function as an adhesive layer by the above-mentioned heating and pressing, but on the other hand, the transfer paper can be easily separated from the cloth or the like. Therefore, the adhesive strength is reduced by a dye fixing process by steaming or the like. That is, it is desirable that the layer of the mixed paste has a property that the adhesive strength is easily reduced by applying moisture in the step of fixing the dye by steaming or the like or the step of peeling the printing paper.
スチーミング等による処理工程により、繊維材料や皮革材料への染料の固着及び発色が行われ、且つ転写紙が剥離された後は、通常、水洗、ソーピング等の洗浄工程が行われる。混合糊は、この洗浄工程で容易に洗浄され除去できる性質を有することが望ましい。 After a dyeing process is performed on the fiber material or the leather material by a treatment process such as steaming, and the transfer paper is peeled off, a washing process such as washing with water or soaping is usually performed. Desirably, the mixed paste has a property that can be easily washed and removed in this washing step.
スチーミング等による染料の固着処理後は、従来の転写捺染法における条件と同様な条件で洗浄（水洗、ソーピング、水洗。分散染料の場合は水洗、還元洗浄、水洗）で処理することで、風合いが良好で繊細、濃厚な捺染物を得ることができる。分散染料の場合は洗浄を省略しても風合いが良好で繊細、濃厚な捺染物を得ることができる。 After fixing treatment of the dye by steaming etc., it is treated by washing (washing, soaping, washing with water under the same conditions as in the conventional transfer printing method. In the case of disperse dye, washing with water, reduction washing, washing with water) Good, delicate and dense prints can be obtained. In the case of disperse dyes, even if washing is omitted, delicate and dense prints can be obtained with good texture.
捺染紙の剥離、除去がされた後は、布帛等を洗浄（水洗、ソーピング）することによって、少量ながら布帛に付着している水溶性合成バインダーと天然系糊剤を水洗除去し、繊維の風合いが良好で繊細なプリント生地あるいはプリント製品を得る。ポリエステルなど合成繊維の場合は洗浄工程を省略することも可能である。 After the printed paper is peeled and removed, the fabric and the like are washed (washed with water and soaped) to remove a small amount of the water-soluble synthetic binder and the natural glue adhering to the fabric in a small amount, and the texture of the fiber is removed. Good and delicate printed fabric or printed product. In the case of synthetic fibers such as polyester, the washing step can be omitted.
離型紙を用いる転写捺染の場合は、インク受容層と染料インクが全量布帛へ移行するため、固着されなかった余剰染料と糊剤による排水汚染が大きいという問題がある。しかし、本発明の方法においては、布帛等より剥離された捺染紙には、固着されなかった染料（余剰染料）と混合糊剤の大部分が付着しており、一方、布帛等には余剰染料や混合糊剤がほとんど付着していないので、布帛洗浄時の排水負荷が公知の方法に比べて大幅に軽減される。従って、この点においても、本発明はエコロジー対応の加工法といえる。 In the case of transfer printing using release paper, since the entire amount of the ink receiving layer and the dye ink is transferred to the fabric, there is a problem in that wastewater contamination due to the excess dye and glue not fixed is large. However, in the method of the present invention, most of the unfixed dye (excess dye) and the mixed paste adhere to the printed paper peeled off from the cloth or the like, while the excess dye is attached to the cloth or the like. And the mixed paste is hardly adhered, so that the drainage load at the time of washing the fabric is greatly reduced as compared with the known method. Therefore, also in this respect, the present invention can be said to be a processing method compatible with ecology.
被印刷物
本発明の被印刷物は特に制限されないが、繊維材料からなる布帛や皮革材料などの捺染に好適に適用される。本発明が適用される繊維材料には、例えば、天然繊維材料及び合成繊維材料のいずれもが含まれる。天然繊維材料としては、綿、麻、リヨセル、レーヨン、アセテート等のセルロース系繊維材料、絹、羊毛、獣毛等の蛋白質系繊維材料を挙げることができる。合成繊維材料としては、ポリアミド繊維（ナイロン）やビニロン、ポリエスエル、ポリアクリル等と呼ばれる繊維を挙げることができる。
Printed Material Although the printed material of the present invention is not particularly limited, it is suitably applied to printing of a cloth or a leather material made of a fiber material. The fiber material to which the present invention is applied includes, for example, 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 the synthetic fiber material include polyamide fiber (nylon), and fibers called vinylon, polyester, polyacryl and the like.
本発明が適用される皮革材料としては、動物性皮革、例えば、牛、水牛、豚、馬、羊、山羊、カンガルー、鹿、豹、兎、狐、ラクダ等の天然皮革や公知の製革、なめし工程を経て乾燥したものを挙げることができる。 As the leather material to which the present invention is applied, animal leather, for example, natural leather such as cow, buffalo, pig, horse, sheep, goat, kangaroo, deer, panther, rabbit, fox, camel, and known leathermaking, tanning What dried through a process can be mentioned.
本発明は、これらの繊維材料の織物、編物、不織布、皮革等の単独、混紡、混繊または交織品に適用される。さらに複合系繊維でも良い。
必要に応じて、染料の染着に影響を及ぼす薬剤あるいは染着促進に効果のある薬剤などで布帛等の被印刷物を前処理しても良い。例えば反応染料を捺染する場合は、布帛などの被印刷物に、アルカリ剤として炭酸ソーダ、炭酸カリ、重炭酸ソーダ、珪酸ソーダ、酢酸ソーダ、セスキ炭酸ソーダ、トリクロル酢酸ソーダ等を３〜１５重量％、転写時の黄変防止、転写性向上、染着向上等の目的で尿素を３〜２５重量％、マイグレーション防止剤として親水性増粘物質、例えばアルギン酸ソーダの０．０５〜１重量％を含め混合液を浸漬し、パッド乾燥しても良い。また、酸性染料をプリントする場合は、染着促進剤として酸アンモニウム塩、例えば硫酸アンモニウム、酒石酸アンモニウム等を０．５〜５重量％、マイグレーション防止剤として耐酸性の天然ガム類０．０５〜０．５重量％を含む混合液を浸漬し、パッド乾燥しても良い。しかし、本発明においては、通常こういった前処理は不要である。
The present invention is applied to woven fabrics, knitted fabrics, non-woven fabrics, leathers, and the like, alone, blended, blended, or woven products of these fiber materials. Further, composite fibers may be used.
If necessary, a printed material such as a cloth may be pre-treated with an agent that affects dyeing or an agent that is effective in promoting dyeing. For example, when printing a reactive dye, 3 to 15% by weight of an alkali agent such as sodium carbonate, potassium carbonate, sodium bicarbonate, sodium silicate, sodium acetate, sodium sesquicarbonate, sodium trichloracetate, etc. is applied to a printing material such as a fabric. A mixture containing 3 to 25% by weight of urea and 0.05 to 1% by weight of a hydrophilic thickener such as sodium alginate as a migration inhibitor for the purpose of preventing yellowing, improving transferability, and improving dyeing. You may soak and dry a pad. When printing an acid dye, an acid ammonium salt such as ammonium sulfate or ammonium tartrate is used as a dyeing accelerator in an amount of 0.5 to 5% by weight, and an acid-resistant natural gum is used as a migration inhibitor in an amount of 0.05 to 0.1%. A mixed solution containing 5% by weight may be immersed and the pad may be dried. However, in the present invention, such pre-processing is usually unnecessary.

＜評価結果＞
表１に評価結果を示す。表１から明らかなように、本発明によれば、繊細なデザインの画像を、被印刷物である布帛に精細かつ濃厚に染着することができた。また、本発明によって転写捺染印刷を行った布帛は、柔軟な風合いを有していた。
その一方で、透気抵抗度が大きい転写紙を用いた比較例では、繊細なデザインを染着した際の画像の精細さおよび濃厚さが、実施例と比較して劣っていた。
また、本発明の捺染印刷用紙は、捺染印刷後の剥離性が良好で、容易に剥離することができた。
<Evaluation results>
Table 1 shows the evaluation results. As is clear from Table 1, according to the present invention, it was possible to dye a finely designed image finely and densely on the cloth to be printed. Moreover, the fabric subjected to the transfer printing according to the present invention had a soft texture.
On the other hand, in the comparative example using the transfer paper having a high air resistance, the fineness and richness of the image when a delicate design was dyed were inferior to those of the example.
The textile printing paper of the present invention had good peelability after textile printing and could be easily peeled.
