Abstract
Description
本発明は水変色性布帛及びそれを用いた水変色性布帛セット、水変色性布帛の製造方法に関する。更に詳細には乾燥した状態（非吸液状態）と、水を含浸した状態（吸液状態）では異なる様相を示す水変色性布帛及びそれを用いた水変色性布帛セット、水変色性布帛の製造方法に関する。 The present invention relates to a water-discolorable fabric, a water-discolorable fabric set using the same, and a method for producing a water-discolorable fabric. More specifically, a water-coloring cloth showing different appearances in a dry state (non-liquid absorption state) and a water-impregnated state (liquid-absorbing state), a water-coloring cloth set using the same, and a water-coloring cloth. Regarding the manufacturing method.
従来、着色された布帛上に低屈折率顔料をバインダー樹脂と共に分散状態に固着させた多孔質層を設けてなり、多孔質層が乾燥状態で白色を呈して下層を隠蔽し、吸液により多孔質層が透明化して下層の色を視認することができる水変色性布帛が開示されている（例えば、特許文献１参照）。
前記水変色性布帛は、水の付着により色変化を楽しむことができるとしても、多孔質層を布帛上に形成する際、低屈折率顔料とバインダー樹脂が布帛に浸透して十分な隠蔽性を発現できなかったり、多孔質層が不均一に形成されて、乾燥状態で下層の色が視認されることがあった。更に、布帛に浸透した低屈折率顔料とバインダー樹脂によって繊維間の固着を生じて布帛の風合いを損なうことがあった。
Conventionally, a porous layer in which a low refraction pigment is fixed together with a binder resin in a dispersed state is provided on a colored cloth, and the porous layer becomes white in a dry state to conceal the lower layer, and is porous by absorbing liquid. A water-discolorable fabric in which the quality layer is transparent and the color of the lower layer can be visually recognized is disclosed (see, for example, Patent Document 1).
Even if the water-discolorable fabric can enjoy the color change due to the adhesion of water, when the porous layer is formed on the fabric, the low refractive index pigment and the binder resin permeate the fabric to provide sufficient hiding property. In some cases, it could not be expressed or the porous layer was formed non-uniformly, and the color of the lower layer was visually recognized in a dry state. Further, the low refractive index pigment and the binder resin that have penetrated into the fabric may cause adhesion between the fibers and impair the texture of the fabric.
本発明は、多孔質層が乾燥状態で下層を十分に隠蔽すると共に、明瞭な色変化を視認することのできる水変色性布帛及びそれを用いた水変色性布帛セット、水変色性布帛の製造方法を提供しようとするものである。 INDUSTRIAL APPLICABILITY According to the present invention, a water-discolorable fabric in which the porous layer sufficiently conceals the lower layer in a dry state and a clear color change can be visually recognized, a water-discolorable fabric set using the same, and a water-discolorable fabric are manufactured. It seeks to provide a method.

The transparent resin layer is provided on the printed fabric.
When the transparent resin layer is formed with the ink for forming the porous layer, which will be described later, the transparent resin layer can prevent the ink from penetrating into the printing fabric to form a uniform porous layer, and is porous. When the layer is dry, the lower layer can be sufficiently concealed.
Further, since the ink forming the porous layer does not penetrate into the printed fabric, the texture and soft texture of the fabric can be maintained.
Examples of the resin forming the transparent resin layer include amide resin, olefin resin, ethylene-vinyl acetate resin, acrylic resin, epoxy resin, epoxy-acrylate resin, urethane resin, ethylene resin, and urethane-. Acrylic resin, melamine resin, phenol resin, urea resin, urea resin, urea-melamine resin, diallyl phthalate tree, ester resin, alkyd resin, maleinized rosin, vinyl butyral resin, cellulose resin Examples thereof include resins, amide resins, two-component curable resins, ultraviolet curable resins, and electron beam curable resins.
As the transparent resin layer, a heat-meltable resin and a two-component curable resin are preferably used.
Further, it is preferable to use a resin having a glass transition point (Tg) of 20 ° C. or lower because the soft texture of the printed fabric can be maintained.
The transparent resin layer may be formed directly on the printing fabric, but a transfer sheet provided with the transparent resin layer applied by applying a transparent resin on a base material having releasability is bonded to the printing fabric. After heat-sealing, the base material can be removed to form a transparent resin layer.
It is also possible to adhere to the printing fabric via the adhesive resin layer and remove the base material to form a transparent resin layer.
前記透明性樹脂層上に設けられる多孔質層は、低屈折率顔料をバインダー樹脂と共に分散状態に固着させた層であり、乾燥状態と吸液状態で透明性が異なる層である。
前記低屈折率顔料としては、珪酸及びその塩、バライト粉、硫酸バリウム、炭酸バリウム、炭酸カルシウム、石膏、クレー、タルク、アルミナホワイト、炭酸マグネシウム等が挙げられ、これらは屈折率が１．４〜１．８の範囲にあり、水を吸液すると良好な透明性を示すものである。
なお、前記珪酸の塩としては、珪酸アルミニウム、珪酸アルミニウムカリウム、珪酸アルミニウムナトリウム、珪酸アルミニウムカルシウム、珪酸カリウム、珪酸カルシウム、珪酸カルシウムナトリウム、珪酸ナトリウム、珪酸マグネシウム、珪酸マグネシウムカリウム等が挙げられる。

また、前記低屈折率顔料は二種以上を併用することもできる。
前記低屈折率顔料の粒子径は特に限定されるものではないが、０．０３〜１０．０μｍのものが好適に用いられる。
前記珪酸は、乾式法により製造させる珪酸であってもよいが、湿式法により製造される珪酸（以下、湿式法珪酸と称する）が特に効果的であり、この点を説明すると、珪酸は非晶質の無定形珪酸として製造され、その製造方法により、四塩化ケイ素等のハロゲン化ケイ素の熱分解等の気相反応を用いる乾式法によるもの（以下、乾式法珪酸と称する）と、ケイ酸ナトリウム等の酸による分解等の液相反応を用いる湿式法によるものとに大別され、乾式法珪酸と湿式法珪酸とでは構造が異なり、前記乾式法珪酸は珪酸が密に結合した三次元構造を形成するのに対して、湿式法珪酸は、珪酸が縮合して長い分子配列を形成した、所謂、二次元構造部分を有している。
従って、前記乾式法珪酸と比較して分子構造が粗になるため、湿式法珪酸を多孔質層に適用した場合、乾式法珪酸を用いる系と比較して乾燥状態における光の乱反射性に優れ、常態での隠蔽性が大きくなるものと推察される。
また、前記多孔質層は、水を吸液させるものであるから、湿式法珪酸は乾式法珪酸に比べて粒子表面にシラノール基として存在する水酸基が多く、親水性の度合いが大であり、好適に用いられる。
なお、前記多孔質層の常態での隠蔽性と吸液状態での透明性を調整するために、湿式法珪酸と共に、他の低屈折率顔料を併用することもできる。
The porous layer provided on the transparent resin layer is a layer in which a low refractive index pigment is fixed together with a binder resin in a dispersed state, and the transparency is different between a dry state and a liquid absorbing state.
Examples of the low refractive index pigment include silicic acid and salts thereof, barite powder, barium sulfate, barium carbonate, calcium carbonate, gypsum, clay, talc, alumina white, magnesium carbonate and the like, and these have a refractive index of 1.4 to 1.4 to. It is in the range of 1.8 and shows good transparency when it absorbs water.
Examples of the salt of silicate include aluminum silicate, potassium aluminum silicate, sodium aluminum silicate, aluminum calcium silicate, potassium silicate, calcium silicate, sodium calcium silicate, sodium silicate, magnesium silicate, potassium magnesium silicate and the like.
Silicic acid is mentioned as a preferably used low refractive index pigment.
Further, two or more kinds of the low refractive index pigments can be used in combination.
The particle size of the low refractive index pigment is not particularly limited, but those having a particle size of 0.03 to 10.0 μm are preferably used.
The silicic acid may be a silicic acid produced by a dry method, but a silicic acid produced by a wet method (hereinafter referred to as a wet method silicic acid) is particularly effective. Explaining this point, the silicic acid is amorphous. It is produced as a quality amorphous silicic acid, and depending on the production method, a dry method using a vapor phase reaction such as thermal decomposition of silicon halide such as silicon tetrachloride (hereinafter referred to as dry silicic acid) and sodium silicate are used. The dry method silicic acid and the wet method silicic acid have different structures, and the dry method silicic acid has a three-dimensional structure in which silicic acid is tightly bonded. On the other hand, the wet method silicic acid has a so-called two-dimensional structural portion in which silicic acid is condensed to form a long molecular arrangement.
Therefore, since the molecular structure is coarser than that of the dry silicic acid, when the wet silicic acid is applied to the porous layer, the diffuse reflection of light in the dry state is excellent as compared with the system using the dry silicic acid. It is presumed that the concealment property under normal conditions will increase.
Further, since the porous layer absorbs water, the wet method silicic acid has more hydroxyl groups existing as silanol groups on the particle surface than the dry method silicic acid, and has a high degree of hydrophilicity, which is suitable. Used for.
In addition, in order to adjust the hiding property of the porous layer in a normal state and the transparency in a liquid absorbing state, another low refractive index pigment can be used in combination with the wet method silicic acid.
前記多孔質層中の低屈折率顔料は、粒子径、比表面積、吸油量等の性状に左右されるが、常態での隠蔽性と吸液状態での透明性を共に満足するためには、塗布量が１〜５０ｇ／ｍ２であることが好ましく、より好ましくは、５〜５０ｇ／ｍ２である。１ｇ／ｍ２未満では、常態で十分な隠蔽性を得ることが困難であり、また、５０ｇ／ｍ２を越えると吸液時に十分な透明性を得ることが困難である。

前記バインダー樹脂としては、ウレタン系樹脂、ナイロン樹脂、酢酸ビニル樹脂、アクリル酸エステル樹脂、アクリル酸エステル共重合樹脂、アクリルポリオール樹脂、塩化ビニル−酢酸ビニル共重合樹脂、マレイン酸樹脂、ポリエステル樹脂、スチレン樹脂、スチレン共重合樹脂、ポリエチレン樹脂、ポリカーボネート樹脂、エポキシ樹脂、スチレン−ブタジエン共重合樹脂、アクリロニトリル−ブタジエン共重合樹脂、メタクリル酸メチル−ブタジエン共重合樹脂、ブタジエン樹脂、クロロプレン樹脂、メラミン樹脂、及び前記各樹脂エマルジョン、カゼイン、澱粉、セルロース誘導体、ポリビニルアルコール、尿素樹脂、フェノール樹脂等が挙げられる。
前記低屈折率顔料とバインダー樹脂の混合比率は、低屈折率顔料の種類及び性状に左右されるが、好ましくは、低屈折率顔料１質量部に対してバインダー樹脂固形分０．５〜２質量部であり、より好ましくは、０．８〜１．５質量部である。低屈折率顔料１質量部に対してバインダー樹脂固形分が０．５質量部未満の場合には、前記多孔質層の実用的な皮膜強度を得ることが困難であり、２質量部を越える場合には、前記多孔質層内部への水の浸透性が損なわれ易くなる。
前記多孔質層は、一般的な塗膜と比較して着色剤に対するバインダー樹脂の混合比率が小さいため、十分な皮膜強度が得られ難い。そこで、耐擦過強度を高めるために、前記のバインダー樹脂のうち、ナイロン樹脂又はウレタン系樹脂を用いると効果的である。
前記ウレタン系樹脂としては、ポリエステル系ウレタン樹脂、ポリカーボネート系ウレタン樹脂、ポリエーテル系ウレタン樹脂等があり、二種以上を併用することもできる。また、前記樹脂が水に乳化分散したウレタン系エマルジョン樹脂や、イオン性を有するウレタン樹脂（ウレタンアイオノマー）自体のイオン基により乳化剤を必要とすることなく自己乳化して、水中に溶解乃至分散したコロイド分散型（アイオノマー型）ウレタン樹脂を用いることもできる。
なお、前記ウレタン系樹脂は水性ウレタン系樹脂又は油性ウレタン系樹脂のいずれを用いることもできるが、水性ウレタン系樹脂、殊に、ウレタン系エマルジョン樹脂やコロイド分散型ウレタン系樹脂が好適に用いられる。
前記ウレタン系樹脂は単独で用いることもできるが、皮膜に必要とされる性能に応じて、他のバインダー樹脂を併用することもできる。ウレタン系樹脂以外のバインダー樹脂を併用する場合、実用的な皮膜強度を得るためには、前記多孔質層のバインダー樹脂中にウレタン系樹脂を固形分質量比率で３０％以上含有させることが好ましい。
前記バインダー樹脂において、架橋性のものは任意の架橋剤を添加して架橋させることにより、さらに皮膜強度を向上させることができる。
前記バインダー樹脂には、水との親和性に大小が存在するが、これらを組み合わせることにより、多孔質層中への浸透時間、浸透度合い、浸透後の乾燥の遅速を調整することができる。更には、適宜分散剤や界面活性剤を添加して前記調整をコントロールすることができる。
The low refractive index pigment in the porous layer depends on properties such as particle size, specific surface area, and oil absorption, but in order to satisfy both the hiding property in the normal state and the transparency in the liquid absorbing state, it is necessary to satisfy both. The coating amount is preferably 1 to 50 g / m 2 , more preferably 5 to 50 g / m 2 . If it is less than 1 g / m 2 , it is difficult to obtain sufficient concealment under normal conditions, and if it exceeds 50 g / m 2 , it is difficult to obtain sufficient transparency at the time of liquid absorption.
The low refractive index pigment is dispersed in a vehicle containing a binder resin as a binder, applied on a support, and then dried to form a porous layer.
Examples of the binder resin include urethane resin, nylon resin, vinyl acetate resin, acrylic acid ester resin, acrylic acid ester copolymer resin, acrylic polyol resin, vinyl chloride-vinyl acetate copolymer resin, maleic acid resin, polyester resin, and styrene. Resin, styrene copolymer resin, polyethylene resin, polycarbonate resin, epoxy resin, styrene-butadiene copolymer resin, acrylonitrile-butadiene copolymer resin, methyl methacrylate-butadiene copolymer resin, butadiene resin, chloroprene resin, melamine resin, and the above. Examples thereof include each resin emulsion, casein, starch, cellulose derivative, polyvinyl alcohol, urea resin, phenol resin and the like.
The mixing ratio of the low refractive index pigment and the binder resin depends on the type and properties of the low refractive index pigment, but preferably, the binder resin solid content is 0.5 to 2 mass with respect to 1 part by mass of the low refractive index pigment. Parts, more preferably 0.8 to 1.5 parts by mass. When the solid content of the binder resin is less than 0.5 parts by mass with respect to 1 part by mass of the low refractive index pigment, it is difficult to obtain a practical film strength of the porous layer, and when it exceeds 2 parts by mass. In addition, the permeability of water into the porous layer is likely to be impaired.
Since the mixing ratio of the binder resin to the colorant is smaller in the porous layer than in a general coating film, it is difficult to obtain sufficient film strength. Therefore, it is effective to use a nylon resin or a urethane-based resin among the above-mentioned binder resins in order to increase the scratch resistance.
Examples of the urethane-based resin include polyester-based urethane resin, polycarbonate-based urethane resin, and polyether-based urethane resin, and two or more of them can be used in combination. Further, a colloid in which the resin is emulsified and dispersed in water or self-emulsified by the ionic group of the ionic urethane resin (urethane ionomer) itself without the need for an emulsifier and dissolved or dispersed in water. A dispersed type (ionomer type) urethane resin can also be used.
As the urethane-based resin, either an aqueous urethane-based resin or an oil-based urethane-based resin can be used, but an aqueous urethane-based resin, particularly a urethane-based emulsion resin or a colloid-dispersed urethane-based resin is preferably used.
The urethane-based resin can be used alone, but other binder resins can also be used in combination depending on the performance required for the film. When a binder resin other than the urethane resin is used in combination, it is preferable that the urethane resin is contained in the binder resin of the porous layer in a solid content mass ratio of 30% or more in order to obtain a practical film strength.
Among the binder resins, those having a crosslinkable property can be further improved in film strength by adding an arbitrary cross-linking agent and cross-linking.
The binder resin has different affinities with water, and by combining these, the permeation time into the porous layer, the degree of permeation, and the slow speed of drying after permeation can be adjusted. Further, the adjustment can be controlled by appropriately adding a dispersant or a surfactant.

合計質量が１００ｇ／ｍ２を超えると布帛としての風合いを損ない易くなると共に、吸液状態における多孔質層の透明性が低下して捺染布帛本来の色を視認し難くなる。
式（１）について、質量Ｂ／質量Ａが０．１未満では、透明性樹脂層に対する多孔質層の割合が低下して布帛として風合いを維持した状態で乾燥状態における多孔質層の遮蔽性が低下して明瞭な色変化を視認でき難くなる。
質量Ｂ／質量Ａが１０を超えると透明性樹脂層に対する多孔質層の割合が大きくなり、透明樹脂層による多孔質層を形成するインキの捺染布帛への浸透防止性が低下して多孔質層が不均一になり、捺染布帛を均一に隠蔽でき難くなると共に、吸液状態において多孔質層が不均一であるため、均一な色変化を視認でき難くなる。

前記水変色性布帛の製造方法としては、布帛にインクジェットインキを用いてインクジェット記録装置により印刷して染着させた後、必要により水洗、加熱乾燥した捺染布帛上に、透明性樹脂を含む印刷インキを用いて印刷し、必要により加熱乾燥して透明性樹脂層を形成し、前記透明性樹脂層上に低屈折率顔料とバインダー樹脂を含むインキを印刷し、必要により加熱乾燥して低屈折率顔料をバインダー樹脂と共に分散状態に固着させた多孔質層を設けて製造される。
The mass A of the transparent resin layer of the water-discolorable fabric obtained as described above is in the range of 5 to 90 g / m 2 , preferably 5 to 70 g / m 2 , and more preferably 5 to 50 g / m 2. Thereby, the hiding property of the porous layer and the flexible texture can be satisfied.
If the mass A is less than 5 g / m 2 , it becomes difficult to form a uniform transparent resin layer on the printed fabric, and therefore it is difficult to form a uniform porous layer on the upper layer. Therefore, the porous layer is a lower layer in a dry state. Is difficult to hide sufficiently.
If the mass A exceeds 90 g / m 2 , the soft texture of the fabric is likely to be impaired.
The total mass of the mass A of the transparent resin layer and the mass B of the porous layer is in the range of 10 to 100 g / m 2 , preferably 20 to 100 g / m 2 , and more preferably 30 to 100 g / m 2 . By satisfying the following formula (1), a clear color change can be visually recognized and a flexible texture can be satisfied.
0.1 ≤ mass B / mass A ≤ 10.0 (1)
When the total mass is less than 10 g, the shielding property in the dry state is lowered, and the color change between the dry state and the liquid absorbing state is reduced.
If the total mass exceeds 100 g / m 2 , the texture of the fabric is likely to be impaired, and the transparency of the porous layer in the liquid absorbing state is lowered, making it difficult to visually recognize the original color of the printed fabric.
Regarding the formula (1), when the mass B / mass A is less than 0.1, the ratio of the porous layer to the transparent resin layer decreases, and the shielding property of the porous layer in the dry state while maintaining the texture as a woven fabric is improved. It is lowered and it becomes difficult to visually recognize a clear color change.
When the mass B / mass A exceeds 10, the ratio of the porous layer to the transparent resin layer increases, and the permeability of the transparent resin layer to prevent the ink forming the porous layer from penetrating into the printing fabric decreases, and the porous layer decreases. Is non-uniform, making it difficult to uniformly conceal the printed fabric, and because the porous layer is non-uniform in the liquid absorbing state, it becomes difficult to visually recognize a uniform color change.
Further, the mass C of the printed fabric is 30 g / m 2 or more, and by satisfying the following formula (2), the concealing property of the porous layer, the clear color change, and the flexible texture can be satisfied.
0.1 ≤ (mass A + mass B) / mass C ≤ 1.0 (2)

Comparative Example 1
On a white cotton broad cloth (texture amount: 100 g / cm 2 woven cloth), yellow, cyan, magenta, and black non-discolorable inkjet water-based inks containing a reactive dye as a colorant are used. A colorful floral pattern was process-printed with an inkjet printing machine, dyed by steam treatment, washed with water, and dried by heating to obtain a printed fabric.
Wet method silicic acid [trade name: Nipseal E-200, manufactured by Nippon Silica Industry Co., Ltd.], urethane emulsion [trade name: Hydran HW-930, manufactured by DIC Co., Ltd., solid content 50%] on the printed fabric. White screen printing made by uniformly mixing and stirring 30 parts, 40 parts of water, 0.5 part of silicone-based defoamer, 3 parts of thickener for water-based ink, 1 part of ethylene glycol, and 3 parts of blocked isocyanate-based cross-linking agent. A 100-mesh screen plate was used for solid printing on the entire surface, and the mixture was dried and cured at 130 ° C. for 5 minutes to form a porous layer (40 g / m 2 ) to obtain a water-discolorable cloth.
前記水変色性布帛は乾燥状態では白色を呈しているものの、捺染布帛に印刷された花柄は多孔質層を介して視認することができる。
多孔質層上から水を付着させると、多孔質層に水が浸透して透明化し、捺染布帛に印刷された花柄が視認されるが、乾燥状態でも花柄が視覚されるため、乾燥状態と吸液状態における変化性に乏しかった。
Although the water-discolorable fabric is white in a dry state, the floral pattern printed on the printed fabric can be visually recognized through the porous layer.
When water is attached from above the porous layer, the water permeates into the porous layer and becomes transparent, and the floral pattern printed on the textile is visible, but the floral pattern is visible even in the dry state, so it is in a dry state. There was little change in the liquid absorption state.
