Description

【0001】
【発明の属する技術分野】
この発明は、籐細工用素材の染色方法に関する。
【0002】
【従来の技術】
ヤシ科のつる性植物である籐は、東南アジア(主としてインドネシア)、アジア大陸などの熱帯から亜熱帯にかけて多く分布する植物であり、その茎が軽く、しなやかで堅牢性があり、曲げたり、編んだりして自由なデザインができるので、家具その他の細工用素材としての材料として賞用されている。
【0003】
このような籐の茎の表面には、エナメル質またはホーロー質と呼ばれる表皮があり、それより内側の茎の芯の部分の長手方向には、通気性のある管状の組織を有する。
【0004】
このような籐を細工用素材として用いるには、そのまま茎の全体を乾燥させるか、または機械を用いて表皮を剥いで皮籐(ピール)と籐芯に分けて乾燥させ、必要に応じて防腐および着色加工をする。
【0005】
籐の表皮を含む籐細工用素材は、そのままよりもステインや樹脂系染料や顔料を塗布して耐久性を向上させると共に、装飾性を高めて多様な需要に対応している。
【0006】
従来の籐細工用素材の着色方法としては、染料や顔料を溶解した木材用の着色剤を調製し、これを油やワニスに溶解した油性ステインまたは水に溶解した水性ステインを塗布する方法がある。
【0007】
また、年輪のある木材の表面をできるだけ斑(むら)なく着色する方法としては、鉄、亜鉛、クロムなどの金属塩からなる鉱物性塩の水溶液を染み込ませ、さらに硫酸塩、過塩素酸塩などの過酸化物の水溶液を染み込ませて反応させる木材用の鉱物質染料が知られている(特許文献1参照。)。
【0008】
【特許文献1】
特表2002−502328号公報(特許請求の範囲)
【0009】
【発明が解決しようとする課題】
しかし、上記した従来の木材系染料または染色方法では、籐細工用素材について、その表皮部分とそれより内側の芯の部分を同様な濃さに染色できないという問題がある。
【0010】
この問題の要因は、籐の表皮がエナメル質またはホーロー質と呼ばれる緻密で撥水性のある部分で形成されており、また茎の内部は、長手方向に通気性があり液状の染料は茎の内部に深く浸透するが、茎の表皮からはじかれて少しの染料しか着色に作用せず、薄い色にしか着色できないということにある。
【0011】
また、従来の染色方法として、先ず鉱物性塩の水溶液を染み込ませ、次いで過酸化物の水溶液を染み込ませて着色反応させる方法では、多量の素材を2種類の染色液槽に移し変える必要があり、染色作業が煩雑になるという問題点がある。
【0012】
そこで、この発明の課題は、上記した問題点を解決し、染料が籐の茎の内部にも茎の表皮にもほぼ同様な濃さの色で着色でき、しかも染色作業が煩雑にならない籐細工用素材の染色方法とすることである。
【0013】
【課題を解決するための手段】
上記の課題を解決するために、この発明においては、鉄製容器内で籐の表皮を含む籐細工用素材を加熱された塩基性染料液に浸漬し、次いで乾燥させることからなる籐細工用素材の染色方法としたのである。
【0014】
上記したように構成されるこの発明の染色方法は、鉄製容器内で塩基性染料液に浸漬して加熱することにより、籐の表皮に塩基性染料と結合しやすい何らかの化学的変化が生じているものと考えられ、例えば籐の表皮に鉄イオンまたは塩化鉄または過塩素酸鉄が接触し、その状態で酸性下に陽極に荷電した塩基性染料が籐の表皮とよく結合して染色されているものとも考えられる。
【0015】
このようにして籐の表皮に塩基性染料が良く染色されると、本来染色されやすい多孔質の籐の内部の染色の程度と同様な色調になり、むらなく染色されるのである。
【0016】
このような方法は、一つの容器内で起こる反応を利用しているため、作業は簡単で効率の良い染色工程である。
【0017】
また、上記の染色方法をより確実におこなうためには、加熱された塩基性染料液に浸漬する際、大気圧下で90〜110℃の煮沸状態に加熱された塩基性染料液に5〜15時間浸漬する上記の籐細工用素材の染色方法とすることが好ましく、塩基性染料が、ビスマークブラウンを使用することが、より好ましい染色方法である。前記の染色時間が5時間未満の短時間では、表皮まで充分に着色することは困難であり、15時間を超える長時間浸漬してもそれ以上に濃く着色することは困難であって、実用性を損なうからである。
【0018】
【発明の実施の形態】
この発明に用いる籐は、籐細工用素材として利用できる籐であればよく、特にその種類を限定して用いる必要はないが、例えば代表的な籐の種類であるカラムス マルガリータ(Calamus margaritae)のほか、その近縁種などであり、例えばカラムス(Calamus)属、ダエモノロプス (Daemonorhops)属、ケラトロブス(Ceratolobus)属などのものが挙げられる。また、利用できる籐素材の一般名を挙げると、ロタン セガ、ロタン ロンティ、ロタン トヒチ、ロタン マナウなどである。
【0019】
籐の表皮を含む籐細工用素材は、茎をそのまま乾燥させたのもの、または機械を用いて表皮を剥いで皮籐(ピール)とするか、または表皮を含めて細長い板状に形成したものなどが例示できるが、その他にも籠、マット、家具など各籐細工の用途に応じて形成された素材であってもよい。
【0020】
この発明に用いる鉄製容器は、特に鉄の種類は限定されないが、酸性条件で加熱された際に、鉄イオンを放出しやすいように、ステンレス鋼以外のものを採用することが好ましい。また、錆止めなどのためにフッ素樹脂コーティングされたものも好ましくなく、鋳鉄などのように鉄系素材をそのままに内面を形成した容器が好ましい。
【0021】
この発明に用いる塩基性染料液は、酸性でプラスに荷電されてカチオン性の染料イオンになり、特に酸性で水溶性の高い塩基性染料である。このような塩基性染料は、芳香族環に置換したアミノ基(−NH2、−NHR、−NR2)が塩酸などの酸性分と塩を作っており、一般式はD−NH3+Cl-で示される。
【0022】
代表的な塩基性染料としては、ビスマークブラウン(茶粉とも通称される。)、(日本化学工業所社製:ビスマークブラウン B コンク)、ビスマークブラック、メチレンブルー(マゼンダ)、オーラミン、メチルバイオレット、マラカイトグリーン、水性染料(水性ステイン、WBST-2131 RED MAHONY SKS SBY)などが挙げられる。
【0023】
染色条件の酸性下で浸漬するには、塩酸、硫酸、その他の酸化剤で染料液をpH調整すればよく、例えばpH2.7〜3.5に調整して好ましい結果を得ている。
【0024】
乾燥工程では、浸漬に用いた染料を液切りし、その後、自然乾燥させるか、または温風などの低湿度の空気流中において乾燥させるようにすればよい。
【0025】
【実施例および比較例】
〔実施例1〕
籐(カラムス マルガリータ、素材名:ロタン セガ)の茎表皮を含む厚さ3mm程度の細長い板状に形成した籐細工用素材を多数本準備し、これを鉄製の容器内で加熱されたビスマークブラウン(日本化学工業所社製:ビスマークブラウン B コンク)を1%を含有する水溶液であり、pH2.7となるように酸化剤を添加したものに浸漬し、これを大気圧下で90℃の染料液に6時間浸漬した。
【0026】
次いで、液切りした籐細工用素材を60℃の温風で1時間乾燥させて染色された籐細工用素材を得た。
【0027】
得られた籐細工用素材は、塩基性染料が籐の表皮とよく結合して染色されており、染料が籐の茎の内部にも茎の表皮にもほぼ同様な濃さの色で着色され、しかも染色作業が比較的簡単であった。
【0028】
〔比較例1〕
籐(カラムス マルガリータ、素材名:ロタン セガ)の茎表皮を含む厚さ3mm程度の細長い板状に形成した籐細工用素材を多数本準備し、これを鉄製の容器内で加熱されたアニリン染料(ダイロンジャパン社製:ダイロン・マルチ)を1%を含有する水溶液であり、これを大気圧下で70〜80℃の染料液に30〜40分浸漬し、水ですすいだ後に、陰干して自然乾燥させた。
【0029】
得られた籐細工用素材は、染料が籐の表皮に充分に結合しておらず、薄い色に染色されており、また染料は籐の茎の内部に濃い色で着色されており、斑のある染色重量状態であった。
【0030】
【発明の効果】
この発明は、以上説明したように、鉄製容器内で籐の表皮を含む籐細工用素材を加熱された塩基性染料液に浸漬し、次いで乾燥させることからなる籐細工用素材の染色方法としたので、籐の表皮に鉄イオンまたは塩化鉄または過塩素酸鉄が接触し、その状態で酸性下に陽極に荷電した塩基性染料が籐の表皮とよく結合して染色されているものとも考えられ、染料が籐の茎の内部にも茎の表皮にもほぼ同様な濃さの色で着色され、しかも染色作業が比較的簡単で煩雑でない籐細工用素材の染色方法であるという利点がある。
[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for dyeing a rattan work material.
[0002]
[Prior art]
Rattan, a vine plant of the palm family, is a plant that is distributed widely from the tropics to the subtropics such as Southeast Asia (mainly Indonesia) and the Asian continent. Its stem is light, supple and robust, and it is bent and knitted. Because it can be designed freely, it is used as a material for furniture and other work materials.
[0003]
On the surface of such a rattan stem, there is an epidermis called enamel or enamel, and in the longitudinal direction of the core portion of the inner stem, there is a breathable tubular tissue.
[0004]
In order to use such rattan as a material for craftwork, dry the whole stem as it is, or peel off the epidermis using a machine and dry it into a rattan (peel) and rattan core, preserving as necessary And coloring process.
[0005]
The materials for rattanwork, including the rattan skin, are coated with stains, resin-based dyes and pigments to improve durability, and have improved decorativeness to meet various demands.
[0006]
As a conventional method for coloring a rattan material, there is a method of preparing a colorant for wood in which dyes and pigments are dissolved and applying an oily stain dissolved in oil or varnish or an aqueous stain dissolved in water. .
[0007]
In addition, as a method of coloring the surface of wood with tree rings as evenly as possible, an aqueous solution of a mineral salt composed of a metal salt such as iron, zinc or chromium is soaked, and sulfate, perchlorate, etc. There is known a mineral dye for wood in which an aqueous solution of a peroxide is soaked and reacted (see Patent Document 1).
[0008]
[Patent Document 1]
Japanese translation of PCT publication No. 2002-502328 (Claims)
[0009]
[Problems to be solved by the invention]
However, the above-mentioned conventional wood dyes or dyeing methods have a problem that the surface of the rattanwork material and the core part inside it cannot be dyed to the same density.
[0010]
The cause of this problem is that the rattan skin is formed of dense and water-repellent parts called enamel or enamel, and the inside of the stem is breathable in the longitudinal direction and the liquid dye is inside the stem Although it penetrates deeply into the skin, it is repelled from the epidermis of the stem and only a small amount of dye acts on the coloration, and it can be colored only in a light color.
[0011]
In addition, as a conventional dyeing method, a method in which an aqueous solution of a mineral salt is first soaked and then an aqueous solution of a peroxide is soaked to cause a color reaction, it is necessary to transfer a large amount of material to two kinds of dyeing baths. There is a problem that the dyeing work becomes complicated.
[0012]
Accordingly, the object of the present invention is to solve the above-mentioned problems, and the dye can be colored with a similar color to the inside of the rattan stalk and the skin of the stalk, and the dyeing work is not complicated. It is to make it the dyeing | staining method of the raw material.
[0013]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, in the present invention, a rattanworking material comprising immersing a rattanworking material containing a rattan skin in a heated iron basic dye solution in an iron container and then drying it. The dyeing method was used.
[0014]
In the dyeing method of the present invention configured as described above, some chemical change that easily binds to the basic dye occurs in the rattan skin by being immersed and heated in a basic dye solution in an iron container. For example, iron ion or iron chloride or iron perchlorate is in contact with the rattan skin, and the basic dye charged to the anode under acidity is well bonded to the rattan skin and dyed. It can be considered a thing.
[0015]
When the basic dye is well dyed on the rattan skin in this way, the color tone becomes similar to the degree of dyeing inside the porous rattan, which is easily dyed, and is dyed evenly.
[0016]
Since such a method uses a reaction that occurs in one container, the operation is simple and efficient.
[0017]
Moreover, in order to perform said dyeing | staining method more reliably, when immersed in the heated basic dye liquid, it is 5-15 in the basic dye liquid heated to the boiling state of 90-110 degreeC under atmospheric pressure. It is preferable to use the dyeing method for the above-mentioned rattanwork material soaked for a long time, and it is more preferable that the basic dye is bismark brown. When the dyeing time is less than 5 hours, it is difficult to sufficiently color the epidermis, and even when immersed for a long time exceeding 15 hours, it is difficult to color deeper than that. It is because it damages.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
The rattan used in the present invention is not particularly limited as long as it can be used as a material for wickerwork. For example, in addition to the typical rattan type, Calamas margaritae (Calamus margaritae) And related species such as the genus Calamus, Daemonorhops, Ceratolobus and the like. Common names of rattan materials that can be used include Rotan Sega, Rotan Ronti, Roto Tohiti, and Rotan Manau.
[0019]
The material for rattanwork including the rattan skin can be obtained by drying the stem as it is, or by peeling the skin using a machine to make a peel (peel), or by forming a thin plate shape including the skin, etc. However, it may be a material formed in accordance with the use of each rattanwork, such as a basket, mat, and furniture.
[0020]
The iron container used in the present invention is not particularly limited in the type of iron, but it is preferable to employ a material other than stainless steel so that iron ions are easily released when heated under acidic conditions. Moreover, the thing coated with a fluororesin for rust prevention etc. is not preferable, and the container which formed the inner surface as it is, such as cast iron, is preferable.
[0021]
The basic dye solution used in the present invention is acidic and positively charged to become a cationic dye ion, and is an acidic and highly water-soluble basic dye. In such a basic dye, an amino group (—NH 2 , —NHR, —NR 2 ) substituted on an aromatic ring forms a salt with an acidic component such as hydrochloric acid, and the general formula is D-NH 3+ Cl - represented by.
[0022]
Representative basic dyes include Bismarck Brown (also known as tea powder), (Nippon Chemical Industry Co., Ltd .: Bismarck Brown B Conch), Bismarck Black, Methylene Blue (Magenta), Auramin, Methyl Violet, Malachite Green And aqueous dyes (aqueous stain, WBST-2131 RED MAHONY SKS SBY).
[0023]
In order to immerse under the acidity of the dyeing conditions, the pH of the dye solution may be adjusted with hydrochloric acid, sulfuric acid, or other oxidizing agent. For example, a preferable result is obtained by adjusting the pH to 2.7 to 3.5.
[0024]
In the drying step, the dye used for the immersion may be drained and then naturally dried or dried in a low-humidity air stream such as warm air.
[0025]
Examples and Comparative Examples
