Description

色漆資材及び色漆スリット糸Color lacquer material and color lacquer slit yarn
　本発明は、着物や和装小物等に用いられる織物や編物の原糸となる漆糸に関する。 The present invention relates to a lacquer yarn used as a raw yarn of a woven or knitted fabric used for a kimono or a small kimono.
　着物や和装小物等に用いられる織物や編物等の原糸として用いられる糸の一つに漆糸がある。漆糸は、和紙の上に漆を薄く塗工し、これを一定幅に細く裁断したものを芯糸に巻き付けて形成される。細く裁断したものは漆スリット糸とも呼ばれ、該漆スリット糸は漆糸の材料として用いられる他、漆スリット糸のまま織物や編物に織り込まれることもある。 漆 Lacquer yarn is one of the yarns used as the original yarns of woven or knitted fabrics used for kimonos and kimono accessories. The lacquer yarn is formed by thinly coating lacquer on Japanese paper, cutting the lacquer into a certain width, and winding it around a core yarn. The finely cut yarn is also called a lacquer slit yarn, and the lacquer slit yarn is used as a material for the lacquer yarn, and may be woven into a woven or knitted fabric as the lacquer slit yarn.
　漆は、樹木から採取された樹液を原料とする茶褐色透明の天然樹脂である。漆を和紙の上に塗工し、乾燥させて漆層を形成した場合、漆層の厚みが或る大きさに達するまでは漆層は柔らかい状態で存在し、その大きさを超えると漆層は硬く割れやすくなる。漆糸または漆スリット糸の場合は、和紙に漆を薄く塗工して柔らかい漆層を形成することで、折り曲げても割れない漆糸、漆スリット糸を得ている。 Lacquer is a brown transparent natural resin made from sap collected from trees. When lacquer is applied on Japanese paper and dried to form a lacquer layer, the lacquer layer exists in a soft state until the thickness of the lacquer layer reaches a certain size. Is hard and easily cracked. In the case of lacquer yarns or lacquer slit yarns, lacquer yarns and lacquer slit yarns that are not cracked even when bent are obtained by thinly applying lacquer to Japanese paper to form a soft lacquer layer.
　漆は、そのまま和紙に塗工しても茶褐色の漆糸または漆スリット糸しか得ることができない。そこで、漆に顔料を混ぜたものを和紙に塗工することで、漆糸や漆スリット糸に様々な色彩を付与することが行われている。しかしながら、顔料を含有する漆は漆単体に比べて和紙に対する接着力が低下する。そこで、接着力の低下を補うために、下地として顔料の含有量が少ない漆を和紙の上に置き、その上に顔料を多く含有する漆を重ねて漆層を形成する手法が広く採用されている。ところが、この手法では、顔料を含まない通常の漆層よりも厚みが大きくなり、漆層が硬くなる。このため、漆層が変形し難くなり、漆糸や漆スリット糸の柔軟性が低下する。なお、漆本来の色とは異なる色を有する漆糸および漆スリット糸をそれぞれ本明細書では色漆糸および色漆スリット糸と呼ぶこととする。 Even if lacquer is coated on Japanese paper as it is, only brown lacquer yarn or lacquer slit yarn can be obtained. Therefore, lacquer yarns and lacquer slit yarns are given various colors by applying a mixture of lacquer and pigment to Japanese paper. However, the lacquer containing the pigment has lower adhesive strength to Japanese paper than the lacquer alone. In order to compensate for the decrease in adhesive strength, a method has been widely adopted in which lacquer with a low pigment content is placed on Japanese paper as a base material, and lacquer containing a large amount of pigment is overlaid on it to form a lacquer layer. I have. However, in this method, the thickness is larger than that of a normal lacquer layer containing no pigment, and the lacquer layer is hard. For this reason, the lacquer layer is less likely to be deformed, and the flexibility of the lacquer yarn or the lacquer slit yarn is reduced. In addition, the lacquer yarn and the lacquer slit yarn having a color different from the original color of the lacquer are respectively referred to as a color lacquer yarn and a color lacquer slit yarn in this specification.
　また、特許文献１には、和紙の上に漆を塗工し、その上に、開繊させて薄く延ばした繊維体（霞状透視性ウェブ）を接着し、さらにその上に透明フィルムを接着したものを細く裁断した装飾糸が開示されている。この装飾糸では、霞状透視性ウェブを通して漆層が見えるため、漆層が、霞んだような深みのある色となる。しかしながら、この装飾糸は、和紙の上に漆層、霞状透視性ウェブを含む接着剤、フィルムが積層されており、一般的な漆糸又は漆スリット糸に比べて厚みが大きくなるため、柔軟性に欠ける。 Further, in Patent Document 1, lacquer is applied on Japanese paper, and a fibrous body (hazy transparent web) which is spread and thinned is adhered thereon, and a transparent film is further adhered thereon. A decorative yarn obtained by cutting the obtained material into small pieces is disclosed. In this decorative yarn, since the lacquer layer is visible through the haze transparent web, the lacquer layer has a haze-like deep color. However, this decorative yarn is made by laminating a lacquer layer, an adhesive containing a haze-like transparent web, and a film on Japanese paper, and is thicker than a general lacquer yarn or lacquer slit yarn. Lack of sex.
　一方、着物や和装小物では、金属光沢を有する糸が織り込まれた織物が用いられることがある。金属光沢を有する糸は、和紙の表面に金箔や銀箔を漆等で張り付けたもの、あるいは、ポリエステル製フィルムの上にアルミニウム等の金属を蒸着したものを細く裁断することで作製され、金銀糸（金糸および銀糸）とも呼ばれる。金銀糸が織り込まれることによって華やかな雰囲気の織物が得られる。しかしながら、金銀糸の金属光沢は表面的なものであるため、漆糸や漆スリット糸とともに金銀糸が織り込まれた場合でも、漆の色が変化するわけではなく、また、金銀糸の金属光沢によって漆自身の色彩が損なわれてしまう。 On the other hand, in kimonos and small kimonos, a woven fabric in which a yarn having a metallic luster is woven may be used. Threads with metallic luster are produced by cutting gold paper or silver foil on the surface of Japanese paper with lacquer or by evaporating a metal such as aluminum on a polyester film, and cutting the gold and silver threads ( Gold and silver). A gorgeous woven fabric can be obtained by weaving the gold and silver threads. However, since the metallic luster of gold and silver threads is superficial, the color of the lacquer does not change even if the gold and silver threads are woven together with the lacquer threads and lacquer slit threads. The color of the lacquer itself will be impaired.

　本発明が解決しようとする課題は、柔軟性を低下させることなく、また、漆自身の色彩を損なうことなく、内面的な金属光沢を有する色漆スリット糸および色漆糸が得られる色漆資材を提供することである。 The problem to be solved by the present invention is to provide a color lacquer material from which a color lacquer slit yarn and a color lacquer yarn having an internal metallic luster can be obtained without lowering the flexibility and without impairing the color of the lacquer itself. It is to provide.
　上記課題を解決するために成された本発明に係る色漆資材の第１の態様は、
　a) ベースシートと、
　b) 該ベースシートの上に積層された光反射層と、
　c) 該光反射層の上に積層された漆層と、
　を備え、
　前記光反射層が、金属粉末を含有する透光性材料から成ることを特徴とする。 The first aspect of the color lacquer material according to the present invention made in order to solve the above problems,
a) a base sheet;
b) a light reflecting layer laminated on the base sheet;
c) a lacquer layer laminated on the light reflecting layer,
With
The light reflection layer is made of a translucent material containing a metal powder.
　本発明においては、ベースシートの上に光反射層と漆層が積層されているだけであるため、色漆資材の柔軟性の低下を抑えることができる。また、光反射層に入射した光が金属粉末によって様々な方向に反射され、漆層を通して外部に放出されるため、変化に富んだ金属光沢が漆層の内側から付与される。本発明では、透光性材料として、例えば接着剤、目止め材等として用いられる水溶性樹脂、油溶性樹脂を用いることができる。また、光反射層には、１種類の透光性材料が含まれていてもよく、複数種類の透光性材料が含まれていてもよい。さらに、光反射層には、１種類の金属粉末が含まれていてもよく、２種類以上の金属粉末が含まれていてもよい。透光性材料は、主に、ベースシートの上に金属粉末を接着するために用いられる。したがって、透光性材料の中に金属粉末が完全に埋もれるほどの量を使用する必要はない。つまり、金属粉末の透光性材料から金属粉末の一部が突出した状態にあってもよい。このような状態（光反射層の上面が凸凹な状態）であっても、光反射層の上に漆層を積層することにより色漆資材の上面は平坦面となる。また、光反射層の上面が凸凹となることによって該光反射層と漆層の接触面積が大きくなり、両者の接合強度が向上する。さらに、光反射層の厚みを薄くすることができるため、色漆資材の柔軟性の低下をより一層抑えることができる。 に お い て In the present invention, since the light reflection layer and the lacquer layer are merely laminated on the base sheet, a decrease in the flexibility of the color lacquer material can be suppressed. In addition, since the light incident on the light reflecting layer is reflected in various directions by the metal powder and emitted to the outside through the lacquer layer, a varied metallic luster is imparted from the inside of the lacquer layer. In the present invention, as the translucent material, for example, a water-soluble resin or an oil-soluble resin used as an adhesive, a filler, or the like can be used. Further, the light reflecting layer may include one type of translucent material, or may include a plurality of types of translucent materials. Further, the light reflecting layer may include one type of metal powder, or may include two or more types of metal powder. The translucent material is mainly used for bonding metal powder on the base sheet. Therefore, it is not necessary to use an amount such that the metal powder is completely buried in the translucent material. That is, a part of the metal powder may protrude from the light transmitting material of the metal powder. Even in such a state (the upper surface of the light reflecting layer is uneven), the upper surface of the colored lacquer material becomes a flat surface by laminating the lacquer layer on the light reflecting layer. In addition, since the upper surface of the light reflecting layer is uneven, the contact area between the light reflecting layer and the lacquer layer is increased, and the bonding strength between the two is improved. Further, since the thickness of the light reflection layer can be reduced, the decrease in the flexibility of the color lacquer material can be further suppressed.
　本発明において、前記色漆資材は、さらに、前記光反射層と前記漆層の間に形成された、タンニンを含有する水性エマルジョン層を有することが好ましい。
　前記水性エマルジョン層を設けた目的は、光反射層と漆層の接着性を高めることである。したがって、上記目的を達成することができるように、水性エマルジョン層の厚みや水性エマルジョン層を形成する範囲を設定すればよい。タンニンは、多くの植物に含まれることが知られており、タンニンを含む代表的な植物材料として、柿の果実、茶葉、ゴボウの根、マンゴー樹皮がある。 In the present invention, the color lacquer material preferably further includes an aqueous emulsion layer containing tannin formed between the light reflection layer and the lacquer layer.
The purpose of providing the aqueous emulsion layer is to enhance the adhesion between the light reflection layer and the lacquer layer. Therefore, the thickness of the aqueous emulsion layer and the range for forming the aqueous emulsion layer may be set so that the above object can be achieved. Tannin is known to be contained in many plants, and typical plant materials containing tannin include persimmon fruits, tea leaves, burdock roots, and mango bark.
　また、本発明では、前記漆層が、染料が混入された漆から構成されていることが好ましい。
　染料を混入させることにより漆層を着色することができる。また、染料は、水、有機溶剤等の媒体中に溶解する。このため、媒体に不溶である顔料と異なり、漆に染料を混入させても、その接着力がほとんど低下しない。したがって、漆層の厚みを大きくしなくても漆層と光反射層を十分接合させることができるため、漆層を着色したことにより該漆層の柔軟性が低下することがない。また、染料が溶解した状態で漆層の中に存在するため、漆本来の透明度を維持したまま漆層を着色することができる。したがって、光反射層の上に着色された漆層を積層したことにより、光反射層による反射光量が低下することを抑えることができる。 In the present invention, it is preferable that the lacquer layer is composed of lacquer mixed with a dye.
The lacquer layer can be colored by mixing a dye. The dye is dissolved in a medium such as water or an organic solvent. For this reason, unlike a pigment which is insoluble in a medium, even if a dye is mixed into lacquer, its adhesive strength hardly decreases. Therefore, since the lacquer layer and the light reflecting layer can be sufficiently bonded without increasing the thickness of the lacquer layer, the flexibility of the lacquer layer is not reduced by coloring the lacquer layer. Further, since the dye is present in the lacquer layer in a dissolved state, the lacquer layer can be colored while maintaining the original lacquer transparency. Therefore, by laminating the colored lacquer layer on the light reflecting layer, it is possible to suppress a decrease in the amount of light reflected by the light reflecting layer.
　また、上記課題を解決するために成された本発明に係る色漆資材の第２の態様は、
　a) ベースシートと、
　b) 該ベースシートの上面に積層された光反射層と、
　c) 該光反射層の上面に積層された漆層と、
　を備え、
　前記漆層が、染料が混入された漆から成ることを特徴とする。 Further, a second aspect of the color lacquer material according to the present invention made in order to solve the above-mentioned problems is as follows:
a) a base sheet;
b) a light reflecting layer laminated on the upper surface of the base sheet;
c) a lacquer layer laminated on the upper surface of the light reflection layer,
With
The lacquer layer is made of lacquer mixed with a dye.
　上述したように、染料が混入された漆から漆層を構成することにより、漆層の厚みを大きくしなくても漆層と光反射層を十分接合させることができる。したがって、本発明の第２の態様においても、漆層を着色したことにより該漆層の柔軟性が低下することがない。また、染料が溶解した状態で漆層の中に存在するため、漆本来の透明度を維持したまま漆層を着色することができる。したがって、光反射層の上に着色された漆層を積層したことにより、光反射層による反射光量が低下することを抑えることができる。 し た As described above, by forming the lacquer layer from the lacquer mixed with the dye, the lacquer layer and the light reflection layer can be sufficiently bonded without increasing the thickness of the lacquer layer. Therefore, also in the second aspect of the present invention, coloring of the lacquer layer does not reduce the flexibility of the lacquer layer. Further, since the dye is present in the lacquer layer in a dissolved state, the lacquer layer can be colored while maintaining the original lacquer transparency. Therefore, by laminating the colored lacquer layer on the light reflecting layer, it is possible to suppress a decrease in the amount of light reflected by the light reflecting layer.
　本発明において、前記ベースシートには、紙製シート、樹脂製シート、木製シート、金属製シート等、様々な材質のシートであって、様々な厚みのもの、様々な硬さ・柔らかさのものを用いることができる。ベースシートとして、洋紙や和紙、樹脂製フィルム等の薄いシートを用いた場合は、折り曲げや切断等の加工が容易な色漆資材を提供することができる。特に、ベースシートを和紙から構成すると、柔らかな色漆資材を得ることができるため、色漆資材を細く切断して色漆糸を作製する場合に好適である。 In the present invention, the base sheet is a sheet of various materials, such as a paper sheet, a resin sheet, a wooden sheet, a metal sheet, etc., of various thicknesses, of various hardness and softness. Can be used. When a thin sheet such as Western paper, Japanese paper, or a resin film is used as the base sheet, it is possible to provide a color lacquer material that can be easily folded or cut. In particular, if the base sheet is made of Japanese paper, a soft colored lacquer material can be obtained, and thus it is suitable for producing a colored lacquer yarn by cutting the colored lacquer material finely.
　本発明においては、前記色漆資材から前記ベースシートを除いた厚みが、該ベースシートの厚みよりも小さいことが好ましい。この構成により、ベースシートの上に光反射層と漆層を、あるいは光反射層と水性エマルジョン層と漆層を、この順に積層することによって、ベースシートの触感や質感が大きく損なわれることがない。また、色漆資材から前記ベースシートを除いた厚みを小さくしたことの結果として漆層の厚みも小さくなるため、色漆資材を曲げたときに漆層にひびが入りにくくなり、見映えがよい。また、環境（温度や湿度等）の変化に伴い色漆資材に生じる歪みを小さくすることができる。そのため、日本のような温帯地域だけでなく、乾燥地域や高湿地域、高温地域においても、良質な色漆スリット糸や色漆糸、布を提供することができる。 に お い て In the present invention, the thickness of the color lacquer material excluding the base sheet is preferably smaller than the thickness of the base sheet. With this configuration, by laminating the light reflection layer and the lacquer layer on the base sheet, or the light reflection layer, the aqueous emulsion layer, and the lacquer layer in this order, the tactile feel and texture of the base sheet are not significantly impaired. . Also, since the thickness of the lacquer layer is also reduced as a result of reducing the thickness of the color lacquer material excluding the base sheet, the lacquer layer is less likely to crack when the colored lacquer material is bent, and the appearance is good. . In addition, distortion generated in the color lacquer material due to a change in environment (temperature, humidity, and the like) can be reduced. Therefore, it is possible to provide high quality colored lacquer slit yarns, colored lacquer yarns, and cloths not only in temperate regions such as Japan but also in dry regions, high humidity regions, and high temperature regions.
　また、本発明において、漆層を構成する漆が精製漆から成ることが好ましい。精製漆の規格については日本工業規格Ｋ－５９５０に規定されており、従来一般には、精製漆は原料漆液または生漆に所定の処理を施した後、ごみ等の固形物を除去することにより得られる。本発明では、従来の一般的な方法で得られた精製漆の他、特許文献２に記載されている方法で得られた精製漆を用いることができる。特許文献２に記載されている方法で得られた精製漆は「ＭＲ漆（登録商標）」として株式会社佐藤喜代松商店より市販されており、一般的な精製漆に比べて乾燥硬化が速い、塗膜の耐候性に優れる、塗膜の硬度が高い、耐沸騰水性に優れる、といった特徴を有する。したがって、ＭＲ漆を用いることにより、耐候性や耐沸騰水性、加工性に優れた、丈夫な色漆資材を得ることができる。また、ＭＲ漆は乾燥硬化が速いため、色漆資材の製造時間を短縮できるという効果もある。 漆 In the present invention, the lacquer constituting the lacquer layer is preferably composed of purified lacquer. The standard of purified lacquer is stipulated in Japanese Industrial Standard K-5950. Generally, purified lacquer is obtained by subjecting raw lacquer liquor or raw lacquer to a predetermined treatment and then removing solids such as garbage. Can be In the present invention, purified lacquer obtained by the method described in Patent Document 2 can be used in addition to purified lacquer obtained by a conventional general method. Purified lacquer obtained by the method described in Patent Document 2 is commercially available as “MR lacquer (registered trademark)” from Kiyomatsu Sato Co., Ltd. It has features such as excellent weather resistance of the film, high hardness of the coating film, and excellent boiling water resistance. Therefore, by using MR lacquer, a durable color lacquer material excellent in weather resistance, boiling water resistance and workability can be obtained. In addition, since MR lacquer is dried and cured quickly, there is also an effect that the production time of colored lacquer material can be reduced.
　上述した第１の態様および第２の態様の色漆資材は様々な用途に利用することができる。例えば、前記色漆資材は、包装用シート、壁紙用シート等として使用することができる。また、前記色漆資材を適宜の大きさの正方形のシートに切断して日本の折り紙のように使用することができる。前記色漆資材を折り紙のように使用するときは、できるだけ薄くて柔らかなベースシートを用いることが好ましい。また、前記色漆資材は、適宜の形状や大きさに切断して装飾品や工芸品に加工することができる。また、前記色漆資材を一定の幅に裁断することにより、色漆スリット糸が得られ、該色漆スリット糸を芯糸に巻き付けることにより色漆糸が得られる。すなわち、本発明に係る色漆スリット糸は、上述した第１の態様又は第２の態様の色漆資材を一定の幅に裁断して成ることを特徴とする。 色 The colored lacquer materials of the first and second embodiments described above can be used for various purposes. For example, the colored lacquer material can be used as a packaging sheet, a wallpaper sheet, or the like. Further, the color lacquer material can be cut into square sheets of an appropriate size and used like Japanese origami. When the color lacquer material is used like origami, it is preferable to use a base sheet that is as thin and soft as possible. Further, the color lacquer material can be cut into an appropriate shape and size to be processed into a decorative article or a craft. Further, by cutting the color lacquer material into a certain width, a color lacquer slit yarn is obtained, and by winding the color lacquer slit yarn around a core yarn, a color lacquer yarn is obtained. That is, the color lacquer slit yarn according to the present invention is characterized in that the color lacquer material of the above-described first or second embodiment is cut into a fixed width.
　本発明の第１の態様においては、柔軟性の低下を抑えつつ、漆自身の色彩を生かした内面的な金属光沢を有する色漆資材が得られるため、このような色漆資材から作製される色漆スリット糸および色漆糸も柔軟で且つ漆の色彩に内面的な金属光沢を付加したものとなる。また、本発明の第２の態様においては、着色された漆層を備えた構成であっても、強い内面的な金属光沢を有する、柔軟な色漆資材が得られるため、このような色漆資材から作製される色漆スリット糸および色漆糸も、強い内面的な金属光沢を有する、柔軟なものとなる。そのため、上記色漆スリット糸や該色漆スリット糸から形成される色漆糸を用いることにより、漆自身の色彩を損なうことなく優れた金属光沢色を有する、しなやかな織物や編物を作製することができる。 In the first aspect of the present invention, a color lacquer material having an internal metallic luster utilizing the color of the lacquer itself can be obtained while suppressing a decrease in flexibility, and thus the lacquer material is produced from such a color lacquer material. The color lacquer slit yarn and the color lacquer yarn are also flexible and have an inner metallic luster added to the color of the lacquer. Further, in the second aspect of the present invention, even with a configuration provided with a colored lacquer layer, a soft colored lacquer material having a strong inner metallic luster can be obtained. Colored lacquer slit yarns and colored lacquer yarns made from materials are also flexible with strong internal metallic luster. Therefore, by using the color lacquer slit yarn and the color lacquer yarn formed from the color lacquer slit yarn, it is possible to produce a supple fabric or knit having an excellent metallic luster color without impairing the color of the lacquer itself. Can be.

　以下、本発明を詳細に説明する。
＜ベースシート＞
　本発明の色漆資材に用いるベースシートは、色漆資材の用途に応じた適宜の厚さ、柔らかさの材料から成るシートを用いることができる。一般的には、前記ベースシートは、厚みが０．１ｍｍ以下の薄い洋紙、和紙、樹脂フィルムが好ましく、特に、色漆資材を一定の幅に細く裁断して色漆スリット糸にしたり、該色漆スリット糸を芯糸に巻き付けて色漆糸にしたりする場合は、０．０５ｍｍ以下の非常に薄い和紙を用いることが好ましい。 Hereinafter, the present invention will be described in detail.
<Base sheet>
As the base sheet used for the color lacquer material of the present invention, a sheet made of a material having an appropriate thickness and softness according to the use of the color lacquer material can be used. In general, the base sheet is preferably thin paper having a thickness of 0.1 mm or less, Japanese paper, and a resin film. In particular, the color lacquer material is finely cut into a certain width to form a color lacquer slit yarn, When a lacquer slit yarn is wound around a core yarn to form a colored lacquer yarn, it is preferable to use a very thin Japanese paper of 0.05 mm or less.
＜光反射層＞
　光反射層は、金粉や銀粉、アルミ箔粉等の金属粉末を含有する透光性材料から構成することができる。透光性材料に対する金属粉末の比率（重量％）は２０～４０重量％程度が好ましい。透光性材料は、ベースシートの上に金属粉末を固定することができる量があればよく、金属粉末の間の隙間を完全に埋めるほどの量が無くてもよい。透光性材料が金属粉末の間の隙間に充填されておらず、光反射層の上面に金属粉末の一部が露出している状態（つまり、光反射層の上面が凸凹な状態）であっても、光反射層の上に形成される漆層、あるいは水性エマルジョン層と漆層によって光反射層の上面の凸凹が埋まるため、光反射層の機能上、問題がない。 <Light reflection layer>
The light reflecting layer can be made of a light-transmitting material containing a metal powder such as a gold powder, a silver powder, and an aluminum foil powder. The ratio (% by weight) of the metal powder to the translucent material is preferably about 20 to 40% by weight. The translucent material may have an amount capable of fixing the metal powder on the base sheet, and may not have such an amount as to completely fill the gap between the metal powders. The gap between the metal powders is not filled with the translucent material, and a part of the metal powder is exposed on the upper surface of the light reflecting layer (that is, the upper surface of the light reflecting layer is uneven). However, since the unevenness on the upper surface of the light reflecting layer is filled with the lacquer layer formed on the light reflecting layer or the aqueous emulsion layer and the lacquer layer, there is no problem in the function of the light reflecting layer.
　また、光反射層は、ベースシートの上に、金や銀、アルミニウムなどの金属を真空蒸着したり、金や銀、アルミニウムなどの金属を圧延してなる金属箔を貼り付けたりすることにより構成することができる。 The light reflection layer is formed by vacuum-depositing a metal such as gold, silver, or aluminum on a base sheet, or attaching a metal foil obtained by rolling a metal such as gold, silver, or aluminum. can do.
＜水性エマルジョン層＞
　水性エマルジョン層は、光反射層の上に水性エマルジョンを塗布することにより形成される。水性エマルジョン層は、光反射層と漆層を強く接着させるために設けられる。水性エマルジョン層は、光反射層の上面全体に形成されていることが好ましいが、光反射層の上面に水性エマルジョン層で覆われていない領域が存在していても構わない。 <Aqueous emulsion layer>
The aqueous emulsion layer is formed by applying an aqueous emulsion on the light reflecting layer. The aqueous emulsion layer is provided to strongly adhere the light reflection layer and the lacquer layer. The aqueous emulsion layer is preferably formed on the entire upper surface of the light reflection layer, but a region not covered by the aqueous emulsion layer may be present on the upper surface of the light reflection layer.
　水性エマルジョンは、例えばタンニンを含む植物材料を圧搾して得られた絞り汁をそのまま用いたり、或いは、絞り汁に酵母菌を加えて発酵させたりしたものを用いることができる。水性エマルジョンの例として柿渋液が挙げられる。渋柿（果実）の搾り汁には水分、タンニン、果実片、金属イオンが含まれており、この絞り汁を静置すると不純物が塊状になって沈澱し、タンニン成分の溶け込んだ透明な上澄み液が得られる。この上澄み液が「柿渋液」と呼ばれるものであり、この上澄み液は、そのまま（原液で）、あるいは水で薄めて使用することができる。 As the aqueous emulsion, for example, a juice obtained by squeezing a plant material containing tannin can be used as it is, or a juice obtained by adding yeast to the juice and fermenting can be used. An example of the aqueous emulsion is persimmon juice. The juice of astringent persimmon (fruit) contains water, tannins, fruit pieces, and metal ions. When this juice is allowed to stand, impurities precipitate in the form of lumps and a clear supernatant liquid in which the tannin component is dissolved is produced. can get. This supernatant is called “persimmon juice”, and the supernatant can be used as it is (as a stock solution) or diluted with water.
＜漆層＞
　漆層は、光反射層の上に直接、或いは光反射層の上に水性エマルジョンを塗布し、その上に漆を塗布することにより形成される。
　漆層は漆単独で構成しても良く、染料が混入された漆から構成しても良い。 <Lacquer layer>
The lacquer layer is formed by applying an aqueous emulsion directly on the light reflection layer or by applying an aqueous emulsion on the light reflection layer, and then applying lacquer thereon.
The lacquer layer may be composed solely of lacquer, or may be composed of lacquer mixed with a dye.
　漆に混入する染料としては、油溶性染料及び水溶性染料のどちらでも使用することができる。ただし、漆は油性成分であるウルシオールを主体とし、このウルシオールの中に水溶性成分が分散状態で存在する油中水滴型エマルジョンであるため、漆に染料を混入する場合は、該染料として、ウルシオールに可溶な油溶性染料を用いることが好ましい。漆に対する染料の混合比率（重量％）は、漆自身の色の濃さや漆に付与したい色の種類や濃さに応じて適宜の値に設定するとよく、一般的には１重量％～２０重量％程度が好ましい。漆自身が茶褐色であることから、茶系の着色を漆に施す場合は染料の混合比率が小さくても十分な発色が得られる。一方、茶褐色の反対色である青緑系の着色を漆に施す場合は、十分な発色を得るためには染料の混合比率を大きくする。ただし、染料の混合比率が大きくなると漆の硬化時間や乾燥時間が長くなる。また、漆の硬化時間や乾燥時間は、漆の種類（漆を採取した樹木の種類、該樹木の生育地等）によって異なり、さらには、周囲環境（温度、湿度）の影響を受ける。したがって、色漆資材を製造する毎に、複数の混合比率で染料を漆に混入したものを調製し、それらの硬化時間・乾燥時間や漆層の発色から、適切な混合比率を求めるようにするとよい。 染料 Either oil-soluble dyes or water-soluble dyes can be used as dyes to be mixed into lacquer. However, lacquer is mainly composed of urushiol, which is an oily component, and is a water-in-oil emulsion in which a water-soluble component is present in a dispersed state in this urushiol. It is preferable to use an oil-soluble dye soluble in urushiol. The mixing ratio (% by weight) of the dye to the lacquer may be set to an appropriate value according to the color depth of the lacquer itself and the type and depth of the color desired to be imparted to the lacquer, and is generally 1% by weight to 20% by weight. % Is preferable. Since the lacquer itself is brownish, a sufficient coloring can be obtained even when the mixing ratio of the dye is small, when a brownish color is applied to the lacquer. On the other hand, when a turquoise color, which is the opposite color of brown, is applied to lacquer, the mixing ratio of the dye is increased to obtain a sufficient color. However, when the mixing ratio of the dye increases, the curing time and drying time of the lacquer increase. The curing time and drying time of the lacquer vary depending on the type of the lacquer (the type of tree from which the lacquer is collected, the area where the tree grows, and the like), and are further affected by the surrounding environment (temperature and humidity). Therefore, every time a color lacquer material is manufactured, a mixture of dyes is mixed into the lacquer at multiple mixing ratios, and the appropriate mixing ratio is determined from the curing time, drying time, and color development of the lacquer layer. Good.
　漆層には、一種類の漆を用いてもよいが、複数種の漆を混合したものを用いてもよい。複数種の漆を混合することにより、硬化時間、乾燥時間を調整することができる。
　また、漆層には精製漆を用いるとよく、特に、ＭＲ漆と呼ばれる精製漆を用いることが好ましい。ＭＲ漆は３本ロールミルを用いて精製された漆であり、主成分であるウルシオールの中に水溶性成分（水分、糖タンパク質、水溶性多糖類）が微細な粒子として分散している。漆の硬化に寄与するラッカーゼは水溶性成分の中に存在しており、水溶性成分の粒子が小さいことによりラッカーゼとウルシオールの接触面積が大きくなる。そのため、通常の漆や従来の精製漆よりもウルシオールの重合反応が起き易くなり、硬化時間を短縮することができる。また、ＭＲ漆は、ウルシオール中に存在する水溶性成分の粒子が小さいため、漆の透明度が高いという特徴がある。 One type of lacquer may be used for the lacquer layer, or a mixture of a plurality of types of lacquer may be used. The curing time and the drying time can be adjusted by mixing a plurality of types of lacquer.
Further, it is preferable to use purified lacquer for the lacquer layer, and it is particularly preferable to use purified lacquer called MR lacquer. MR lacquer is lacquer purified using a three-roll mill, in which a water-soluble component (water, glycoprotein, water-soluble polysaccharide) is dispersed as fine particles in urushiol as a main component. Laccase that contributes to the curing of lacquer is present in the water-soluble component, and the contact area between the laccase and urushiol increases due to the small size of the particles of the water-soluble component. Therefore, the polymerization reaction of urushiol is more likely to occur than ordinary lacquer or conventional purified lacquer, and the curing time can be shortened. Further, MR lacquer has a feature that the transparency of lacquer is high because particles of water-soluble components present in urushiol are small.
　金属粉末を含有する水溶性材料、水性エマルジョン、漆の塗布は手作業で行っても良く、エアーブラシやコーター等、適宜の塗装装置を用いても良い。 塗布 The application of the water-soluble material containing the metal powder, the aqueous emulsion, and the lacquer may be performed manually, or an appropriate coating device such as an air brush or a coater may be used.

＜色漆資材の作製手順＞
　図１を参照しつつ、色漆資材の作製手順を説明する。
　まず、エナメル樹脂にうすめ液を添加してエナメル樹脂の粘度を調整した後、そこに金属粉末を混ぜて金属粉末液を調製する。そして、金属粉末液を和紙１０の上に捺染方式で塗工し、乾燥させて金属粉末層２０を形成する（図１（ａ））。この状態では、金属粉末２１と和紙１０、金属粉末２１同士がエナメル樹脂によって接合されているが、金属粉末２１の間には隙間が存在する。 <Procedure for producing colored lacquer materials>
With reference to FIG. 1, a procedure for producing a color lacquer material will be described.
First, the viscosity of the enamel resin is adjusted by adding a thinning solution to the enamel resin, and then the metal powder is mixed therein to prepare a metal powder solution. Then, the metal powder liquid is applied on the Japanese paper 10 by a printing method, and dried to form a metal powder layer 20 (FIG. 1A). In this state, the metal powder 21 and the Japanese paper 10 and the metal powder 21 are joined to each other by the enamel resin, but a gap exists between the metal powders 21.
　次に、水溶性接着剤ＰＶＡを水に溶解してＰＶＡ５％水溶液を調製し、これを金属粉末層２０の上に塗布して乾燥させる。これにより、金属粉末２１とエナメル樹脂、うすめ液、及び水溶性接着剤ＰＶＡからなる光反射層３０が形成される。金属粉末層２０の上に塗布された水溶性接着剤ＰＶＡは、金属粉末２１の間の隙間に入り込み、和紙１０と金属粉末２１、及び金属粉末２１同士を強く接合する。ただし、この状態では、光反射層３０の上面は粗面となっている。
　続いて、光反射層３０の上に柿渋液を塗布し、乾燥させて柿渋層４０を形成する。このとき、光反射層３０の上面が粗面であるため、柿渋層４０と光反射層３０の接触面積が大きくなり、両者は強く接合される（図１（ｃ））。 Next, a 5% aqueous solution of PVA is prepared by dissolving the water-soluble adhesive PVA in water, and this is applied on the metal powder layer 20 and dried. Thereby, the light reflecting layer 30 made of the metal powder 21, the enamel resin, the thinning liquid, and the water-soluble adhesive PVA is formed. The water-soluble adhesive PVA applied on the metal powder layer 20 enters the gaps between the metal powders 21 and strongly joins the Japanese paper 10 with the metal powders 21 and the metal powders 21. However, in this state, the upper surface of the light reflection layer 30 is rough.
Subsequently, a persimmon juice layer is applied on the light reflection layer 30 and dried to form a persimmon juice layer 40. At this time, since the upper surface of the light reflection layer 30 is rough, the contact area between the persimmon juice layer 40 and the light reflection layer 30 increases, and the two are strongly bonded (FIG. 1C).
　次に、ＭＲ漆に油溶性染料を、その濃度が１重量％、２重量％、５重量％、１０重量％となるように添加して着色ＭＲ漆を作製した。
　続いて、着色ＭＲ漆を柿渋層４０の上に塗布し、２日～４日かけて自然乾燥させ、漆層５０を形成した（図１（ｄ））。
　以上により、ベースシートである和紙１０の上に、光反射層３０、柿渋層４０、漆層５０がこの順に積層されてなる色漆資材１が得られた。 Next, an oil-soluble dye was added to the MR lacquer so as to have a concentration of 1% by weight, 2% by weight, 5% by weight, and 10% by weight to prepare a colored MR lacquer.
Subsequently, the colored MR lacquer was applied onto the persimmon astringent layer 40 and dried naturally for 2 to 4 days to form a lacquer layer 50 (FIG. 1 (d)).
As described above, the color lacquer material 1 in which the light reflection layer 30, the persimmon astringent layer 40, and the lacquer layer 50 were laminated in this order on the Japanese paper 10 as the base sheet was obtained.
　得られた色漆資材１の厚みを計測したところ５０μｍであった。和紙１０の厚みが３１μｍであることから、光反射層３０、柿渋層４０、および漆層５０を合わせた厚みは１９μｍとなり、和紙１０の厚みより小さかった。この結果は、着色ＭＲ漆に含まれる油溶性染料の濃度が１重量％、２重量％、５重量％、１０重量％のいずれであっても、ほぼ同じであった。 厚 み When the thickness of the obtained colored lacquer material 1 was measured, it was 50 μm. Since the thickness of the Japanese paper 10 was 31 μm, the total thickness of the light reflection layer 30, the persimmon juice layer 40, and the lacquer layer 50 was 19 μm, which was smaller than the thickness of the Japanese paper 10. This result was almost the same regardless of the concentration of the oil-soluble dye contained in the colored MR lacquer being 1% by weight, 2% by weight, 5% by weight, or 10% by weight.
　また、色漆資材１の色を視認したところ、ＭＲ漆の色（茶褐色）と反対色（補色）に近い青色、緑色の油溶性染料をＭＲ漆に添加したものは、油溶性染料の濃度が５重量％、１０重量％のときに、着色が確認された。一方、ＭＲ漆の色と近い色（赤色）の油溶性染料をＭＲ漆に添加したものは、油溶性染料の濃度が１重量％でも着色を十分、確認することができた。このことから、ＭＲ漆を着色したい色に応じて、ＭＲ漆に添加する油溶性染料の量を調整することが好ましい。 Also, when the color of the color lacquer material 1 was visually confirmed, the concentration of the oil-soluble dye was low when the blue and green oil-soluble dyes, which were close to the color (brown color) of the MR lacquer, were added to the MR lacquer. Coloring was confirmed at 5% by weight and 10% by weight. On the other hand, when the oil-soluble dye of a color (red) close to the color of the MR lacquer was added to the MR lacquer, coloring was sufficiently confirmed even when the concentration of the oil-soluble dye was 1% by weight. For this reason, it is preferable to adjust the amount of the oil-soluble dye to be added to the MR lacquer according to the color to be colored.
　また、図２に示すように、色漆資材１００を１ｍｍ幅に裁断して色漆スリット糸１１０を作製した。この色漆スリット糸１１０は、折り曲げてもヒビが入ることがなく、しなやかな糸であった。また、絹糸ないし化学繊維糸を経糸に、色漆スリット糸１１０を緯糸にして織物を作製したが、途中で緯糸が切れることはなかった。また、得られた織物は金銀箔スリット糸ないし金銀糸を緯糸として用いた場合と同様にジャガード織に対応でき、仕上がりも同程度の柔らかさであった。 (2) As shown in FIG. 2, the color lacquer material 100 was cut into a width of 1 mm to produce a color lacquer slit yarn 110. The color lacquer slit yarn 110 was a flexible yarn without cracking even when bent. In addition, a woven fabric was produced by using a silk thread or a chemical fiber thread as a warp and a color lacquer slit thread 110 as a weft, but the weft was not broken in the middle. Further, the obtained woven fabric was compatible with Jacquard weave in the same manner as in the case of using a gold-silver foil slit yarn or a gold-silver yarn as the weft, and the finish was almost the same softness.
　次に、上記色漆スリット糸１１０を、５００ｍｍの長さに切断したスリット糸片を２０本用意し、これら２０本のスリット糸片のうち１０本については以下の環境試験を行ってから、残り１０本については、環境試験を行わずに、それぞれ引張強さ及び伸び率試験を行った。引張強さ及び伸び率試験は、地方独立行政法人京都市産業技術研究所にて行われた（受付番号２０１７０２２８８、試験完了日：2017年12月4日）。 Next, the color lacquer slit yarn 110 was prepared into 20 slit yarn pieces obtained by cutting to a length of 500 mm, and after performing the following environmental test on 10 of these 20 slit yarn pieces, the remaining Tens were subjected to tensile strength and elongation tests, respectively, without conducting an environmental test. The tensile strength and elongation tests were performed at the Kyoto City Industrial Technology Research Institute (accession number 20172288, test completion date: December 4, 2017).
＜環境試験＞
　以下の(1)-(4)までを１サイクルとし、これを６回繰り返した（６サイクル）。
(1) 温度１０℃、湿度５０％ＲＨの環境下に３時間放置する。
(2) １時間かけて、温度を４０℃に、湿度を９０％ＲＨに調温調湿。
(3) 温度４０℃に、湿度９０％ＲＨの環境下に３時間放置。
(4) １時間かけて、温度を１０℃に、湿度を５０％ＲＨに調温調湿。 <Environmental test>
The following (1) to (4) were defined as one cycle, and this was repeated six times (six cycles).
(1) Leave for 3 hours in an environment of a temperature of 10 ° C. and a humidity of 50% RH.

(3) Leave for 3 hours in an environment of a temperature of 40 ° C and a humidity of 90% RH.
(4) The temperature and humidity are adjusted to 10 ° C. and the humidity to 50% RH over 1 hour.
＜引張強さ及び伸び率試験＞
　JIS L1013 8.5.1に準じた測定。
　試験機の種類：定速伸長形
　つかみ間隔：２０ｃｍ
　引張速度：２０ｃｍ／分
　容量：５０Ｎ <Tensile strength and elongation test>
Measurement according to JIS L1013 8.5.1.
Type of testing machine: Constant speed extension type Gripping interval: 20cm
Tensile speed: 20cm / min Capacity: 50N
　上記環境試験前後のスリット糸片の引張強さ及び伸び率試験の結果を図３及び図４に示す。図３及び図４は、いずれも、１０本のスリット糸片について引張強さ及び伸び率試験を行ったときの変位（ｍｍ）と試験力（Ｎ）との関係を示している。これらの図から、環境試験前のスリット糸片の強度（平均値）は１．７２Ｎ、伸度（平均値）は２．６％であった。一方、環境試験後のスリット糸片の強度（平均値）は１．７８Ｎ、伸度（平均値）は２．７％であった。このように、環境試験の前後で、スリット糸片の強度及び伸度に大きな違いはなかった。このことから、上記実施例で得られた色漆スリット糸１１０は過酷な環境下でも強度及び伸度が変化しないことが分かる。 結果 The results of the tensile strength and elongation test of the slit yarn pieces before and after the above environmental test are shown in FIGS. 3 and 4 show the relationship between the displacement (mm) and the test force (N) when the tensile strength and elongation rate tests were performed on ten slit yarn pieces. From these figures, the strength (average value) of the slit yarn piece before the environmental test was 1.72 N, and the elongation (average value) was 2.6%. On the other hand, the strength (average value) of the slit yarn piece after the environmental test was 1.78 N, and the elongation (average value) was 2.7%. Thus, there was no significant difference in the strength and elongation of the slit yarn pieces before and after the environmental test. This indicates that the color lacquer slit yarn 110 obtained in the above example does not change in strength and elongation even under a severe environment.
　なお、上記の実施例では、いずれも油溶性染料を漆に混入して漆層を形成した、水溶性染料を漆に混入して漆層を形成することも可能である。本発明者は、３色の水溶性染料（ＩＮＫ　ＲＥＤ３４、ＩＮＫ　ＹＥＬＬＯＷ　２７、ＩＮＫ　ＢＬＵＥ　１２（いずれも中央合成化学株式会社製））をそれぞれ漆に混入したものを和紙の上に塗工し、塗膜ができることを確認している。 In each of the above embodiments, the lacquer layer is formed by mixing an oil-soluble dye into lacquer, and the lacquer layer can be formed by mixing a water-soluble dye into lacquer.
