Definitions
- the present invention relates to a sublimation transfer dyeing method for dyeing an object to be dyed using an intermediate recording medium provided with a sublimation transfer toner, and a dyed product obtained by the dyeing method.
- the dyeing method using the electrophotographic method for the hydrophobic fiber typified by polyester cloth or the hydrophobic resin typified by PET film can be roughly divided into two. That is, a direct method in which a toner is directly applied to an object to be dyed, and then a dye contained in the toner is dyed on the object to be dyed by heat treatment; and an intermediate recording is performed after the toner is applied to an intermediate recording medium such as paper. A sublimation transfer method in which the toner application surface of the medium and the object to be dyed are superposed and then heat treatment is performed, and the dye contained in the toner is sublimated and transferred to the object to be dyed.
- the sublimation transfer method is said to be suitable for dyeing for applications where the texture is important, such as clothing such as sports apparel.
- the dye in the toner used for the sublimation transfer method is an easily sublimation type that is excellent in sublimation transfer to hydrophobic fibers by heat treatment, among disperse dyes or oil-soluble dyes suitable for dyeing hydrophobic fibers. Are used.
- the sublimation transfer method When the sublimation transfer method is used in the electrophotographic system, it is possible to dye only the dye out of the plurality of components constituting the toner from the intermediate recording medium to the fiber. As a result, toner constituents other than the dye do not adhere to the dyed fabric, and are suitable for applications in which the texture of the fabric is important, such as clothing; interiors such as sheets and sofas; or beddings; In addition, it is possible to reduce the risk of occurrence of rash, eczema and the like due to toner constituents for people with sensitive skin quality. In addition, the fact that processes such as washing and drying are not required greatly reduces the dyeing process; washing and drying lines and washing water treatment facilities that require high cost, large space and large operating energy There are also merits such as making unnecessary. Therefore, the sublimation transfer method is regarded as an excellent staining method capable of staining even in a small space.
- the ink-jet sublimation transfer dyeing has a problem that an organic solvent, which is one of the components constituting the ink, volatilizes due to heat when transferring the dye and contaminates the working environment.
- an organic solvent which is one of the components constituting the ink
- the electrophotographic system there is no volatile component in the toner and the work environment is not contaminated; the fiber (or its structure) that can be dyed by the appearance of a photosensitive drum capable of outputting up to 900 mm width.
- the size of fabric etc. has become compatible with the sports apparel field; and the dyeing area per unit time is larger than that of the inkjet method (serial printing method); Gathered.
- Sublimation transfer dyeing using an electrophotographic method is disclosed in, for example, the following Patent Documents 1 to 5.
- the electrophotographic system due to the characteristics of the electrophotographic system, even if toner is applied to paper as an intermediate recording medium, the toner remains on the paper surface and does not penetrate into the paper. Therefore, it has been said that it is possible to use inexpensive plain paper without using special paper such as inkjet as the intermediate recording medium, but in the sublimation transfer textile printing method in the electrophotographic method in the test according to the present invention, It was confirmed that sublimation transfer dyeing can be performed on a dyed fabric with high efficiency by using special paper as an intermediate recording medium for electrophotography.
- An object of the present invention is to provide a sublimation transfer dyeing method capable of dyeing an object to be dyed with high efficiency by an electrophotographic method using toner, and an object to be dyed with high efficiency by this dyeing method.
- the present inventors have found that the above problems can be solved by using paper having a specific density as an intermediate recording medium, and have completed the present invention. That is, the present invention relates to the following (1) to (13).
- the intermediate recording medium is JIS P 0001: 1998 3.
- Classification b) Packaging material 1) Cellophane described in relation to paper and paperboard; Sublimation transfer dyeing method according to (1) above, which is paper selected from the group consisting of: (3) The sublimation transfer dyeing method according to (1) or (2), wherein the intermediate recording medium is a paper containing cellulose.

Description
即ち、被染色物へ直接トナーを付与した後、熱処理によってトナー中に含有される染料を被染色物に染着させるダイレクト法;及び、紙等の中間記録媒体にトナーを付与した後、中間記録媒体のトナー付与面と被染色物とを重ね合わせてから熱処理を行い、トナー中に含有される染料を被染色物に昇華転写させる昇華転写法;の2つである。
また、洗浄・乾燥等の工程が不要となることは、染色工程の大幅な削減;高コストかつ大規模なスペースと大規模な稼働エネルギーを必要とする、洗浄・乾燥ライン及び洗浄水の処理設備等の不要化;等のメリットも生じる。
従って、昇華転写法は、小規模なスペースでも染色できる優れた染色方法とされている。
しかし、インクジェット方式の昇華転写染色は、インクを構成する成分の一つである有機溶剤が、染料を転写するときの熱によって揮発し、作業環境を汚染する等の問題がある。
これに対して電子写真方式は、トナー中に揮発成分が存在せず、作業環境を汚染しないこと;900mm幅まで出力可能な感光体ドラムの出現によって、染色できる繊維(又は、その構造物である布等)のサイズがスポーツアパレル分野にも対応可能となったこと;及び、単位時間当たりの染色面積がインクジェット方式(シリアルプリント方式)と比較して大きいこと;等の理由により、近年では注目が集まっている。
一方、電子写真方式はその特性上、中間記録媒体として紙にトナーを付与しても、紙表面にトナーが留まり、紙内部まで浸透することはない。よって、中間記録媒体としてインクジェットの様な専用紙を用いなくても、安価な普通紙を用いることが可能であるとされてきたが、本発明による試験において電子写真方式における昇華転写捺染方法において、電子写真用の中間記録媒体として専用紙を用いることで、高効率で被染色布に昇華転写染色できることが確認された。

トナーの製造方法としては、混練、粉砕、分級の工程を経て作製する粉砕法の他、重合性のモノマーを重合させ、同時に形状や大きさを制御しながらトナーの粒子形成を行う重合トナーの製造方法(例えば、乳化重合法、溶解懸濁法、乳化会合法、ポリエステル伸張法等)を適用することができる。製造を高速に行えるという点では、粉砕法が好ましい。粉砕法によるトナーの製造方法は、下記の製造工程1~3の3つの工程を含むのが一般的である。
染料、樹脂、及び必要に応じて荷電制御剤、ワックス等をヘンシェルミキサー等の混合機で混合し、染料-樹脂混合物を得る工程。
「製造工程2」
前記染料-樹脂混合物を、密閉式ニーダー;又は、1軸もしくは2軸の押出機;等で溶融混練し、冷却して樹脂組成物を得る工程。
「製造工程3」
前記樹脂組成物を、ハンマーミル等で粗粉砕した後、ジェットミル等で微粉砕し、必要に応じてサイクロンを用いて目標とする粒度分布になる様に分級してトナー(トナー粒子)を得る工程。
キャリアとしては、鉄、フェライト、マグネタイト等の金属;これらの金属と、アルミニウム、鉛等の金属との合金;等の、公知の材料からなる磁性粒子を用いることができ、特にフェライト粒子が好ましい。また、磁性粒子の表面を結着樹脂等の被覆剤で被覆したコートキャリアや、結着樹脂中に磁性体微粉末を分散してなるバインダー型キャリア等を用いてもよい。
(1)感光ドラム等の潜像担持体上に露光によって形成された静電潜像を、トナーを用いた現像剤により現像し、トナー像を形成する。
(2)得られたトナー像を転写部材によって紙等の中間記録媒体に転写することにより、中間記録媒体上にトナー画像を形成する。
(3)得られた中間記録媒体を定着器によって加熱、加圧し、中間記録媒体上に形成されたトナー画像を中間記録媒体に定着する。これにより、中間記録媒体への画像の印刷が完了する。
定着器はクリーニング機能を備えるものであってもよい。クリーニングの方法としては、シリコーンオイルをローラに供給してクリーニングする方法;シリコーンオイルを含浸したパッド、ローラ、ウェッブ等でローラをクリーニングする方法;等が挙げられる。
また、被染色物を染色するのに必要なトナー量が少なくて済むので、染色に掛かる費用が少なくてすむようになり、コストメリットに優れた染色方法を提供できるようになった。
さらに、昇華転写後の中間記録媒体に残存する染料の量が非常に少なくなることから、通常では脱墨ができず、焼却等により廃棄されていた昇華転写染色後の中間記録媒体が、再生紙等にリサイクルできる可能性が生じ、環境に優しい染色方法としても期待できる。
実施例中、平均粒子径は、精密粒度分布測定装置「Mulitisizer RTM 3(ベックマン・コールター株式会社製)」を用いて測定した。
