Description
本発明は、蓄光性を有する各種用途の模様紙、その模様紙を製造する方法に関するものである。 The present invention relates to a pattern paper having various phosphorescent properties and a method for producing the pattern paper.
従来、下記特許文献１では、主原料であるコウゾやミツマタなどの繊維に蓄光粉を混ぜ合わせて和紙としている。
上記特許文献１では、和紙の繊維内に蓄光粉が万遍なく入り込むので、蓄光粉の一部しか和紙の外面に表れず、蓄光粉による輝度を確保することが難しい。
この発明は、少量の蓄光性蛍光粉末体により明るく発光させることができる模様紙と、その模様紙の製造方法を提供することを目的としている。
In Patent Document 1, since the phosphorescent powder uniformly enters the fibers of the Japanese paper, only a part of the phosphorescent powder appears on the outer surface of the Japanese paper, and it is difficult to ensure the luminance by the phosphorescent powder.
An object of the present invention is to provide a pattern paper that can emit light brightly with a small amount of phosphorescent phosphor powder and a method for producing the pattern paper.
後記実施形態の図面（図１）の符号を援用して本発明を説明する。
請求項１の発明にかかる模様紙１においては、中空扁平状レーヨン繊維２と蓄光性蛍光粉末体とを凝集させた複数の蓄光凝集塊を模様４として、抄造した下地紙３上に重ねて定着させている。請求項１の発明では、蓄光性蛍光粉末体を混ぜた蓄光凝集塊を模様４として、抄造した下地紙３上に重ねて定着させているので、下地紙３内に蓄光性蛍光粉末体が吸収されず、少量の蓄光性蛍光粉末体により明るく発光させることができる。また、光透過性の高いレーヨン繊維２に蓄光性蛍光粉末体を混ぜた蓄光凝集塊を模様４としているので、蓄光性蛍光粉末体による輝度を高めることができる。さらに、蓄光凝集塊のレーヨン繊維２として中空扁平状のものを利用しているので、蓄光凝集塊の残光蓄光性に必要な光が当り易くなり、発光も見易くなる。
The present invention will be described with reference to the reference numerals of the drawings (FIG. 1) of the embodiment described later.
In the patterned paper 1 according to the invention of claim 1, a plurality of luminous aggregates obtained by agglomerating the hollow flat rayon fiber 2 and the phosphorescent fluorescent powder are formed as a pattern 4 and fixed on the ground paper 3 that has been made. I am letting. In the invention of claim 1, the phosphorescent agglomerated powder mixed with the phosphorescent phosphor powder is fixed on the ground paper 3 as a pattern 4 so that the phosphorescent phosphor powder absorbs the base paper 3. The light can be brightly emitted by a small amount of the phosphorescent phosphor powder. Moreover, since the luminous aggregate obtained by mixing the luminous phosphor powder with the light-transmitting rayon fiber 2 has the pattern 4, the luminance of the luminous fluorescent powder can be increased. Furthermore, since a hollow flat fiber is used as the rayon fiber 2 of the phosphorescent aggregate, light necessary for the afterglow phosphorescent property of the phosphorescent aggregate can be easily hit and light emission can be easily seen.
請求項２の発明においては、模様紙１を下記の方法により製造する。
中空扁平状レーヨン繊維２と蓄光性蛍光粉末体とを液体に混ぜたものを攪拌して分散するとともにこの中空扁平状レーヨン繊維２と蓄光性蛍光粉末体とを凝集剤で凝集し、その中空扁平状レーヨン繊維２と蓄光性蛍光粉末体とを含む複数の蓄光凝集塊を液体に混ぜた凝集塊含有混合液体を製造するとともに、抄造途中で下地紙３としての湿紙を形成する前段階においてその湿紙素材に前記凝集塊含有混合液体を接触させたものを脱水して乾燥させることにより、中空扁平状レーヨン繊維２と蓄光性蛍光粉末体とを凝集させた複数の蓄光凝集塊を模様４として下地紙３上に重ねて定着させた模様紙１を製造する。請求項２の発明では、請求項１の発明の効果に加え、抄造途中で下地紙３としての湿紙を形成する前段階の湿紙素材に前記凝集塊含有混合液体を接触させたので、蓄光凝集塊を模様４として下地紙３上に重ねて定着させ易くなり、蓄光性を有する各種用途の模様紙１を容易に製造することができる。

図１（ｄ）に示す模様紙１は、図１（ａ）に示す下記の概略的過程（蓄光凝集塊の作成と紙の抄造）を経て製造される。
Hereinafter, an embodiment of the present invention will be described with reference to FIG.
The pattern paper 1 shown in FIG. 1 (d) is manufactured through the following schematic process (production of luminous aggregates and paper making) shown in FIG. 1 (a).
図１（ｂ）（ｃ）に示す中空扁平状レーヨン繊維２の１００部と、蓄光性蛍光粉末体の１００部と、凝集剤としての繊維状ビニロンバインダーの３０部とを水により２％に希釈して混ぜた液体を攪拌して分散する。次に、その液体に薬品としてのアクリルアミド・アクリル酸共重合体の０．１％水溶液を０．２％重量入れて攪拌する。その攪拌後、薬品としての硫酸アルミニウムの１０％水溶液を１％重量添加して攪拌するか、または、薬品としてのスチレン系ポリマーを０．２％重量添加して攪拌する。このようにして、中空扁平状レーヨン繊維２と蓄光性蛍光粉末体とを凝集し、その中空扁平状レーヨン繊維２と蓄光性蛍光粉末体とを含む複数の蓄光凝集塊を液体に混ぜた凝集塊含有混合液体を製造する。この中空扁平状レーヨン繊維２は、相対向する平坦壁２ａと相対向する両側壁２ｂとそれらの間の中空部２ｃとからなり、この中空部２ｃについては両平坦壁２ａの内面が互いに接触しても両平坦壁２ａの内面間に若干隙間が生じてもよい。ちなみに、図１（ｂ）において、中空部２ｃが延びる方向の長さＬは２〜１５ｍｍ好ましくは３〜５ｍｍ、両側壁２ｂを互いに結ぶ方向の幅Ｗは４０〜２００μ好ましくは４０〜６０μ、両平坦壁２ａを互いに結ぶ方向の厚さＴは１〜１０μ好ましくは１〜３μにそれぞれ設定されている。また、幅Ｗと厚さＴとの比である扁平比Ｗ：Ｔは１０：１〜７０：１好ましくは２０：１〜３０：１に設定されている。 1 part of hollow flat rayon fiber 2 shown in FIGS. 1B and 1C, 100 parts of phosphorescent fluorescent powder, and 30 parts of fibrous vinylon binder as a flocculant are diluted to 2% with water. Then, the mixed liquid is stirred and dispersed. Next, 0.2% by weight of a 0.1% aqueous solution of acrylamide / acrylic acid copolymer as a chemical is added to the liquid and stirred. After the stirring, 1% by weight of a 10% aqueous solution of aluminum sulfate as a chemical is added and stirred, or 0.2% by weight of a styrene polymer as a chemical is added and stirred. In this way, the aggregate obtained by agglomerating the hollow flat rayon fiber 2 and the phosphorescent fluorescent powder and mixing a plurality of phosphorescent aggregates including the hollow flat rayon fiber 2 and the phosphorescent fluorescent powder with the liquid. A mixed liquid containing is produced. The hollow flat rayon fiber 2 is composed of opposed flat walls 2a, opposed side walls 2b, and hollow portions 2c therebetween, and the inner surfaces of the flat walls 2a are in contact with each other. Alternatively, a slight gap may be formed between the inner surfaces of both flat walls 2a. Incidentally, in FIG. 1 (b), the length L in the direction in which the hollow portion 2c extends is 2 to 15 mm, preferably 3 to 5 mm, and the width W in the direction connecting the side walls 2b to each other is 40 to 200 μ, preferably 40 to 60 μ. The thickness T in the direction connecting the flat walls 2a to each other is set to 1 to 10 μm, preferably 1 to 3 μm. The flatness ratio W: T, which is the ratio of the width W to the thickness T, is set to 10: 1 to 70: 1, preferably 20: 1 to 30: 1.
抄造途中で下地紙３としての湿紙を形成する前段階において、短網抄紙機の短網上で形成された湿紙素材上に前記凝集塊含有混合液体を連続的に供給し、その凝集塊含有混合液体を接触させたものを脱水して乾燥させることにより、中空扁平状レーヨン繊維２と蓄光性蛍光粉末体とを凝集させた多数の蓄光凝集塊を模様４として下地紙３上に重ねて定着させた例えば坪量６０ｇ／ｍ２の模様紙１を製造する。ちなみに、短網抄紙機に代えて長網抄紙機または円網抄紙機で抄紙したり、それらの組み合わせによる抄紙機で抄紙したりすることは可能である。 In the previous stage of forming the wet paper as the base paper 3 in the middle of papermaking, the agglomerate-containing mixed liquid is continuously supplied onto the wet paper material formed on the short net of the short net paper machine, and the aggregate The mixture liquid contacted is dehydrated and dried, so that a large number of phosphorescent aggregates obtained by agglomerating the hollow flat rayon fiber 2 and the phosphorescent phosphor powder are stacked on the base paper 3 as patterns 4. For example, a fixed pattern paper 1 having a basis weight of 60 g / m 2 is manufactured. Incidentally, it is possible to make paper with a long paper machine or a circular paper machine instead of a short paper machine, or with a paper machine with a combination thereof.
このような模様紙１では、抄造途中で下地紙３としての湿紙を形成する前段階の湿紙素材に凝集塊含有混合液体を接触させているので、下地紙３内に蓄光性蛍光粉末体が吸収されず、少量の蓄光性蛍光粉末体により明るく発光させることができるとともに、蓄光凝集塊を模様４として下地紙３上に重ねて定着させ易くなる。また、光透過性の高い中空扁平状レーヨン繊維２を利用しているので、蓄光性蛍光粉末体による輝度を高めることができるとともに、蓄光凝集塊の残光蓄光性に必要な光が当り易くなって発光も見易くなる。 In such a pattern paper 1, since the mixed liquid containing agglomerates is brought into contact with the wet paper web material in the previous stage of forming the wet paper as the base paper 3 in the middle of papermaking, the phosphorescent phosphor powder is contained in the base paper 3. Is not absorbed, and it is possible to emit light brightly with a small amount of phosphorescent phosphor powder, and it is easy to fix the phosphorescent agglomerates as patterns 4 on the base paper 3. Moreover, since the hollow flat rayon fiber 2 with high light transmittance is used, the luminance by the phosphorescent fluorescent powder can be increased, and the light necessary for the afterglow phosphorescence of the phosphorescent agglomerates can be easily hit. The light emission is easy to see.
