Description

本発明は、染料を含有するインキによって着色された転写部材を用いた、布帛への転写捺染法およびそれに用いる転写捺染装置に関する。 The present invention relates to a transfer printing method on a fabric using a transfer member colored with an ink containing a dye, and a transfer printing apparatus used therein.

セルロース繊維を転写捺染する方法として、分散染料を用いる方法が提案されている。しかし、分散染料はセルロース繊維との親和性に乏しいため、堅牢度の点で問題がある。
そのため、昇華性を有しない染料を用い、湿式転写捺染する方法が提案されている。この方法は転写紙上に塗布された転写樹脂層を染料と共にセルロース繊維上に転写移行させ、ついでスチーミングおよびソーピング処理によって発色および転写樹脂層等の除去をおこなうものである。しかし、この方法も転写工程が複雑で作業性の点で満足すべきものではない。
As a method for transferring and printing cellulose fibers, a method using a disperse dye has been proposed. However, since the disperse dye has a poor affinity with the cellulose fiber, there is a problem in terms of fastness.
Therefore, a method of wet transfer printing using a dye having no sublimation property has been proposed. In this method, the transfer resin layer applied on the transfer paper is transferred to the cellulose fibers together with the dye, and then the color is developed and the transfer resin layer and the like are removed by steaming and soaping treatment. However, this method also has a complicated transfer process and is not satisfactory in terms of workability.

そのため、反応性染料を含むインキにより所望の図柄を印刷した転写シートを用いて、これをあらかじめアルカリ剤を含む液で前処理されたセルロース繊維を乾燥したものに重ね合せ、水蒸気中で加熱、加圧する転写捺染する方法が提案されている(特許文献1)。この方法では、セルロース繊維にアルカリ剤を含む液で前処理する工程と、その後、乾燥する工程の二つの工程を必要とする。また、アルカリ剤を塗布した布帛が長期間保存されれば、湿度等の影響によって保存安定性が劣化するという問題がある。 Therefore, using a transfer sheet in which a desired pattern is printed with an ink containing a reactive dye, the cellulose fibers pretreated with a liquid containing an alkaline agent are superposed on a dried one, and heated and added in steam. A method of printing by pressing has been proposed (Patent Document 1). This method requires two steps: a step of pretreating the cellulose fibers with a liquid containing an alkaline agent, and a step of drying the cellulose fibers thereafter. Further, if the fabric coated with the alkaline agent is stored for a long period of time, there is a problem that the storage stability is deteriorated due to the influence of humidity and the like.

Another object of the present invention is to obtain a transfer fabric having excellent color development by quickly using the fabric coated with an alkaline agent for transfer printing without storing it for a long period of time.

本発明においては、転写部材のインク受容層に染料を含有するインクを付与し着色転写部材を得る印刷工程(C)を有することができる。すなわち、転写部材に染料を含有するインクを付与し着色部分を染料で着色して着色転写部材を得る印刷工程(C)を有することが好ましい。
インク受容層に染料を含有するインクを用いて、インクジェット印刷、グラビア印刷、オフセット印刷、スクリーン印刷等の通常の印刷方式により所望の図柄を、印刷することができる。
本発明において、前処理工程(A)は、布帛に染色助剤を付与し処理布帛を得る工程であるのに対し、印刷工程(C)は、転写部材にインクを付与する工程であり、両者は、互いに異なるメディア(布帛/転写部材)に対して処理液(染色助剤/インク)を付与する独立した工程である。別言すれば、転写部材に対して下地として染色助剤を付与し、その上に重ねてインクを付与させる連続工程ではない。
それ故、本発明の転写捺染方法では、染色助剤を付与する位置からインクが付与された着色転写部材の着色部分を処理布帛に転写する位置までの距離を調整することができるので、この距離を長くすればするほど処理布帛の乾燥を促して含水量を少なく調整することができる。従って、転写工程(B)における処理布帛の含水量を最適化することで品質の良い転写を実現することができる。
連続工程を用いた場合には、転写部材に対して下地として染色助剤を付与した後、一旦乾燥させてからその上にインクを付着し、転写工程の前に水分を付与しなければならず、工程が煩雑化し好ましくない。
また本発明では、あらかじめ印刷工程(C)を行い、転写部材にインクを付与した着色転写部材を製造しておき、その着色転写部材を転写工程(B)に供給し、前処理工程(A)からの処理布帛に転写することもできる。
<Printing process (C)>
In the present invention, it is possible to have a printing step (C) of applying an ink containing a dye to the ink receiving layer of the transfer member to obtain a colored transfer member. That is, it is preferable to have a printing step (C) in which an ink containing a dye is applied to the transfer member and the colored portion is colored with the dye to obtain a colored transfer member.
Using an ink containing a dye in the ink receiving layer, a desired pattern can be printed by a usual printing method such as inkjet printing, gravure printing, offset printing, and screen printing.
In the present invention, the pretreatment step (A) is a step of applying a dyeing aid to the cloth to obtain a treated cloth, whereas the printing step (C) is a step of applying ink to the transfer member, both of which. Is an independent step of applying a treatment liquid (dyeing aid / ink) to different media (fabric / transfer member). In other words, it is not a continuous process in which a dyeing aid is applied to the transfer member as a base and ink is applied on top of the dyeing aid.
Therefore, in the transfer printing method of the present invention, the distance from the position where the dyeing aid is applied to the position where the colored portion of the colored transfer member to which the ink is applied is transferred to the treated fabric can be adjusted. The longer the length is, the more the treated fabric can be dried and the water content can be adjusted to be small. Therefore, good quality transfer can be realized by optimizing the water content of the treated fabric in the transfer step (B).
When a continuous process is used, a dyeing aid must be applied to the transfer member as a base, dried once, and then ink is adhered onto the transfer member to add moisture before the transfer process. , The process becomes complicated and is not preferable.
Further, in the present invention, the printing step (C) is performed in advance to manufacture a colored transfer member in which ink is applied to the transfer member, and the colored transfer member is supplied to the transfer step (B) to be supplied to the transfer step (B), and the pretreatment step (A) is performed. It can also be transferred to the treated fabric from.

<前処理工程(A)と転写工程(B)との連続>

<Continuity of pretreatment step (A) and transfer step (B)>
In the present invention, the pretreatment step (A) and the transfer step (B) are continuously performed. "Continuous" means that the treated fabric to which the dyeing aid is applied in the pretreatment step (A) is treated as it is in the order of the steps without removing it from the flow of the steps.
