Description
本発明は、超臨界二酸化炭素を用いて繊維を染色するための染料、超臨界二酸化炭素を用いた繊維の染色方法、前記染色方法により染色された繊維、および化合物に関する。
The present invention relates to a dye for dyeing fibers using supercritical carbon dioxide, a method for dyeing fibers using supercritical carbon dioxide, fibers dyed by the dyeing method, and compounds.
ポリプロピレン樹脂およびポリエチレン樹脂等のポリオレフィン系樹脂は結晶性の熱可塑性樹脂であり、安価、易加工性、高強度、高耐薬品性、高耐擦過性、高耐屈曲性、軽量、低吸湿性、低熱伝導性、高帯電防止性、再生可能等の優れた特性を持っている。
Polyolefin resins such as polypropylene resin and polyethylene resin are crystalline thermoplastic resins that have excellent properties such as low cost, easy processability, high strength, high chemical resistance, high abrasion resistance, high bending resistance, light weight, low moisture absorption, low thermal conductivity, high antistatic properties, and recyclability.
一方で、ポリオレフィン系樹脂は、主鎖、側鎖ともに炭化水素からなる高分子化合物であり、従来の染料化合物との親和性、相溶性が低く、また化学反応に有効な官能基を有していない等の理由により、高濃度かつ高堅牢染色は極めて困難であるとされてきた。
On the other hand, polyolefin resins are polymeric compounds in which both the main chain and side chain are made of hydrocarbons, and because they have low affinity and compatibility with conventional dye compounds and do not have functional groups that are effective in chemical reactions, it has been considered extremely difficult to achieve high-concentration, high-fastness dyeing.
そのために、現在市場にある有色ポリオレフィン系樹脂は、ポリマーペレット等の製造段階で有色顔料を添加し、その後所望の形状に紡糸、成形等を行っているものが大部分を占めている。
For this reason, the majority of colored polyolefin resins currently on the market are made by adding colored pigments during the manufacturing stage of polymer pellets, etc., and then spinning and molding them into the desired shape.
この着色方法では樹脂製品製造工程の初期段階に色を決定する必要がある。また採算性を考慮すると、ひとつの色を一定量以上生産する必要があり、結果的に色選択の自由が制限される。
With this coloring method, the color must be determined at an early stage in the resin product manufacturing process. Also, to be profitable, a certain amount of each color must be produced, which limits the freedom of color selection.
さらに樹脂製品の色を変更する場合は、樹脂製品製造装置内に残存している先の色の着色樹脂を次の色の着色樹脂で置換する工程が必要であり、その際に大量の廃棄樹脂が発生するとともに、時間およびエネルギーを浪費する等の問題が生じる。
Furthermore, when changing the color of a resin product, a process is required to replace the colored resin of the previous color remaining in the resin product manufacturing equipment with colored resin of the next color, which generates large amounts of waste resin and causes problems such as wasting time and energy.
山本洋，繊維学会誌，６１（２００５），３１９－３２１．に記載されているように、ポリプロピレン樹脂およびポリエチレン樹脂は、ポリ塩化ビニル樹脂、ポリスチレン樹脂と並ぶ四大汎用合成樹脂であり、幅広い分野で用いられている。
As described by Hiroshi Yamamoto in Sen-i-Gakkaishi Journal, 61 (2005), 319-321, polypropylene resin and polyethylene resin are among the four major general-purpose synthetic resins, along with polyvinyl chloride resin and polystyrene resin, and are used in a wide range of fields.
しかし合成繊維としてのポリプロピレン樹脂及びポリエチレン樹脂の用途は非常に限定されている。
However, the uses of polypropylene resin and polyethylene resin as synthetic fibers are very limited.
この理由は、前記のとおりポリプロピレン樹脂繊維及びポリエチレン樹脂繊維の高濃度かつ高堅牢染色が極めて困難であり、唯一有効な着色方法である有色顔料による原液着色法では単糸繊度が大きくならざるを得ず、また色選択の自由が制限されること等であると考えられる。
The reason for this is thought to be that, as mentioned above, it is extremely difficult to dye polypropylene resin fibers and polyethylene resin fibers at high concentrations and with high fastness, and the only effective coloring method, the solution coloring method using colored pigments, necessitates a large single yarn size and limits the freedom of color selection.

特公昭３８－１０７４１号公報には、アントラキノン系染料に、炭素数３乃至１２のアルキル基またはシクロアルキル基を置換基として有するフェノキシ基を導入した赤色染料と紫色染料の製造例、及びそれらを使用したポリプロピレン樹脂繊維の染色例が記載されている。
JP 38-10741 B describes examples of producing red and purple dyes in which a phenoxy group having an alkyl or cycloalkyl group with 3 to 12 carbon atoms as a substituent has been introduced into an anthraquinone dye, as well as examples of dyeing polypropylene resin fibers using these dyes.
しかし、これらのアントラキノン系赤色染料またはアントラキノン系紫色染料ではポリオレフィン系樹脂繊維の高濃度染色は困難である。さらに染色に使用する際の染料の形態に関しては、これらのアントラキノン系赤色染料を有機溶剤であるアルコールまたはアセトンに溶解後使用する等の記載があり、環境にやさしいものであるとは言い難い。加えて黄色染料についての記載はない。
However, it is difficult to achieve high-concentration dyeing of polyolefin resin fibers using these anthraquinone red dyes or anthraquinone purple dyes. Furthermore, with regard to the form of the dyes used for dyeing, there is a description that these anthraquinone red dyes should be dissolved in organic solvents such as alcohol or acetone before use, which is hardly environmentally friendly. Furthermore, there is no description of yellow dyes.
特公昭４０－１２７７号公報には、アントラキノン系染料に、炭素数１乃至９のアルキル基、シクロアルキル基またはハロゲノ基を置換基として有するフェノキシ基を導入した青色染料の製造例、及びそれらを使用したポリエステル繊維、ポリアミド繊維、ポリオレフィン系樹脂繊維の染色例が記載されている。

しかし、これらのアントラキノン系青色染料ではポリオレフィン系樹脂繊維の高濃度染色は困難であり、また得られた染色物の染色堅牢性についての具体的な記載はされていない。さらに染色に使用する際の染料の形態に関しては、これらのアントラキノン系青色染料を有機溶剤であるアルコールまたはアセトンに溶解後使用する等の記載があり、環境にやさしいものであるとは言い難い。加えて黄色染料についての記載はない。
However, it is difficult to achieve high-concentration dyeing of polyolefin resin fibers using these anthraquinone blue dyes, and no specific description is made of the dye fastness of the resulting dyed products. Furthermore, with regard to the form of the dyes used for dyeing, there is a description that these anthraquinone blue dyes should be dissolved in organic solvents such as alcohol or acetone before use, which is hardly environmentally friendly. Furthermore, there is no description of yellow dyes.
特公昭４１－３５１５号公報には、アントラキノン系染料に、炭素数１乃至９のアルキル基またはハロゲノ基を置換基として有するフェノキシ基を導入した青色染料の製造例、及びそれらを使用したポリオレフィン系樹脂繊維の染色例が記載されている。

Furthermore, with regard to the form of the dye used for dyeing, there is a description that it should be dissolved in organic solvents such as alcohol or acetone before use, which is hardly environmentally friendly. Furthermore, there is no description of yellow dyes.

British Patent No. 872,882 describes an example of dyeing polyolefin resin fibers using a blue dye in which an alkylamino group or a cycloalkylamino group has been introduced at the alpha position of an anthraquinone dye.
しかしこれらのアントラキノン系青色染料ではポリオレフィン系樹脂繊維の高濃度染色は困難であり、また得られた染色物の染色堅牢性についての具体的な記載はされていない。加えて黄色染料についての記載はない。
However, it is difficult to achieve high-concentration dyeing of polyolefin resin fibers using these anthraquinone blue dyes, and there is no specific description of the color fastness of the resulting dyed products. In addition, there is no description of yellow dyes.
米国特許第３，５３６，７３５号明細書には、アントラキノン系染料に、ｓｅｃ－ブチル基、ｓｅｃ－ペンチル基、ｔｅｒｔ－ペンチル基から選択される２つの置換基を有するフェノキシ基を導入した赤色染料の製造例、及びそれらを使用したポリプロピレン樹脂繊維の染色例が記載されている。

しかしこれらのアントラキノン系赤色染料ではポリオレフィン系樹脂繊維の高濃度染色は困難であり、また得られた染色物の染色堅牢性についての具体的な記載はされていない。さらに染色に使用する際の染料の形態に関しては、有機溶剤であるジメチルホルムアミドに溶解後使用する等の記載があり、こちらは環境にやさしいものであるとは言い難い。加えて黄色染料についての記載はない。
However, it is difficult to achieve high-concentration dyeing of polyolefin resin fibers using these anthraquinone red dyes, and no specific description is made of the dye fastness of the resulting dyed products. Furthermore, with regard to the form of the dye used for dyeing, there is a description that it should be dissolved in dimethylformamide, an organic solvent, before use, which is hardly environmentally friendly. Furthermore, there is no description of the yellow dye.
特開２０１９－２０３２２３号公報には、長鎖アルキル基を有するアントラキノン系黄色染料、アントラキノン系赤色染料またはアントラキノン系青色染料を含有する分散染料組成物を用いてポリプロピレン繊維を水中で染色する染色例が記載されている。
JP 2019-203223 A describes an example of dyeing polypropylene fibers in water using a disperse dye composition containing an anthraquinone yellow dye, an anthraquinone red dye, or an anthraquinone blue dye having a long-chain alkyl group.
しかし記載されている長鎖アルキル基を有するアントラキノン系黄色染料ではポリプロピレン繊維の高濃度染色は困難である。
However, it is difficult to achieve high-concentration dyeing of polypropylene fibers using the anthraquinone-based yellow dyes that have the long-chain alkyl groups described.
特開昭５５－１５２８６９号公報には、長鎖アルキル基を有するモノアゾ系染料の製造例、及びそれらを使用したファインデニールポリエステル繊維の染色例が記載されている。しかしそれらを使用したポリオレフィン系繊維への染色例は記載されていない。加えて黄色染料についての記載はない。
JP Patent Publication 55-152869 describes examples of producing monoazo dyes with long-chain alkyl groups, and examples of dyeing fine denier polyester fibers using them. However, it does not describe examples of dyeing polyolefin fibers using them. In addition, there is no mention of yellow dyes.
またポリオレフィン系樹脂繊維の染色性を改善するために、ポリオレフィン系樹脂繊維の改質についても種々検討されてきた。
Also, various modifications to polyolefin resin fibers have been investigated to improve their dyeability.
改質技術としては、ポリエステル等の可染性樹脂成分の配合、可染性基を有するビニル系単量体等との共重合、ステアリン酸金属塩等の染色促進剤の配合、等種々のものが知られている。
Various modification techniques are known, including the incorporation of dyeable resin components such as polyester, copolymerization with vinyl monomers that have dyeable groups, and the incorporation of dye accelerators such as metal stearates.
これらの改質ポリオレフィン系樹脂繊維の染色性は改善されているものの、染色処理によって糸の強度が低下してしまい、衣服等に用いた場合に強度不足に陥るという問題を有している。
Although the dyeability of these modified polyolefin resin fibers has been improved, the strength of the yarn is reduced by the dyeing process, resulting in a problem of insufficient strength when used in clothing, etc.
ところで、特許第３２５３６４９号公報には、水系染色に代わる染色方法として、超臨界二酸化炭素を染色媒体として用い、疎水性繊維材料を様々な染料で染色すること等が記載されている。
Incidentally, Japanese Patent Publication No. 3253649 describes a dyeing method that uses supercritical carbon dioxide as a dyeing medium to dye hydrophobic fiber materials with various dyes as an alternative to aqueous dyeing.
しかし疎水性繊維材料の一例としてポリプロピレンは記載されているが、実施例にはポリエステル布の染色例のみが記載されており、ポリプロピレン繊維の染色例は記載されていない。
However, although polypropylene is listed as an example of a hydrophobic fiber material, the examples only include dyeing examples of polyester fabric, and do not include examples of dyeing polypropylene fibers.
特許第６７２１１７２号公報には、超臨界二酸化炭素を染色媒体として用い、ポリオレフィン系繊維であるポリプロピレン繊維をアントラキノン系青色染料、アントラキノン系黄色染料、アントラキノン系赤色染料、及びこれらの染料を混合して染色することが記載されている。
Patent Publication No. 6721172 describes the use of supercritical carbon dioxide as a dyeing medium to dye polypropylene fibers, which are polyolefin fibers, with anthraquinone blue dye, anthraquinone yellow dye, anthraquinone red dye, or a mixture of these dyes.
しかし記載されているアントラキノン系黄色染料ではポリプロピレン繊維の高濃度染色は困難である。
However, it is difficult to achieve high-concentration dyeing of polypropylene fibers using the described anthraquinone yellow dyes.
ポリプロピレン樹脂繊維及びポリエチレン樹脂繊維を高濃度かつ高堅牢染色する方法が実用化されると、無着色の小単糸繊度の安価なレギュラー糸を色数制限なく着色することが可能となり、これまでポリプロピレン樹脂繊維及びポリエチレン樹脂繊維が適用されてこなかった衣料や車両内装材等の高い意匠性が要求される分野における新しい用途展開が期待される。
If a method for dyeing polypropylene resin fibers and polyethylene resin fibers with high concentration and high fastness can be put to practical use, it will be possible to color inexpensive, uncolored, small single-fiber regular yarns with no limit on the number of colors, which is expected to lead to new applications in fields where high design quality is required, such as clothing and vehicle interior materials, where polypropylene resin fibers and polyethylene resin fibers have not been used until now.

＜超臨界二酸化炭素を用いた繊維の染色方法＞
本発明は、超臨界二酸化炭素を用いた繊維の染色方法であって、前記本発明の染料を用いて超臨界二酸化炭素存在下に繊維を染色する工程を含む方法である。前記方法において、染色媒体として超臨界二酸化炭素を用いる。 <Method of dyeing textiles using supercritical carbon dioxide>
The present invention relates to a method for dyeing a fiber using supercritical carbon dioxide, which comprises a step of dyeing a fiber with the dye of the present invention in the presence of supercritical carbon dioxide. In the method, supercritical carbon dioxide is used as a dyeing medium.
本発明は、超臨界二酸化炭素を用いた繊維の染色方法であって、前記本発明の染料を用いて超臨界二酸化炭素存在下に繊維を染色する工程を含む方法である。前記方法において、染色媒体として超臨界二酸化炭素を用いる。 <Method of dyeing textiles using supercritical carbon dioxide>
The present invention relates to a method for dyeing a fiber using supercritical carbon dioxide, which comprises a step of dyeing a fiber with the dye of the present invention in the presence of supercritical carbon dioxide. In the method, supercritical carbon dioxide is used as a dyeing medium.
染色媒体として、超臨界二酸化炭素を用いる染色方法は、染色媒体として水を使用する一般的な染色方法と比較して、染色時に水を使用せず、また洗浄工程が不要であるために廃水が発生しない、染色助剤が不要、染色時間が短い、染色媒体である二酸化炭素を再利用可能である等のことから、環境にやさしい染色方法として注目されている。
Compared to the general dyeing method that uses water as the dyeing medium, the dyeing method that uses supercritical carbon dioxide as the dyeing medium does not use water during dyeing, does not require a washing process, and therefore does not generate wastewater, does not require dyeing auxiliaries, has a short dyeing time, and allows the carbon dioxide dyeing medium to be reused. As a result, it has attracted attention as an environmentally friendly dyeing method.
また、前記本発明の染料にてポリオレフィン系樹脂を使用した繊維等を染色した場合、超臨界二酸化炭素は親油性であり、本発明の染料及びポリオレフィン系樹脂ともに親油性であるので、染色媒体、染料、被染色物それぞれの親和性が高く、結果として高品位な染色物が得られる。
In addition, when the dye of the present invention is used to dye fibers or the like that use polyolefin resin, the dye of the present invention and the polyolefin resin are both lipophilic, so there is a high affinity between the dyeing medium, the dye and the object to be dyed, resulting in a high-quality dyed product.
本発明の超臨界二酸化炭素を用いた繊維の染色方法における染色工程は、３１℃以上の温度かつ７．４ＭＰａ以上の圧力で行われるのが好ましい。前記染色温度および染色圧力は、染色媒体である二酸化炭素の臨界点（３１℃における７．４ＭＰａ）以上であることが必要なためである。
The dyeing process in the fiber dyeing method using supercritical carbon dioxide of the present invention is preferably carried out at a temperature of 31°C or higher and a pressure of 7.4 MPa or higher. This is because the dyeing temperature and dyeing pressure must be equal to or higher than the critical point of carbon dioxide, which is the dyeing medium (7.4 MPa at 31°C).
前記染色工程において、染色温度は被染色繊維の樹脂の種類によって主として決定される。前記染色温度、通常は６０乃至１８０℃の範囲であり、好ましくは８０乃至１６０℃の範囲である。
In the dyeing process, the dyeing temperature is mainly determined by the type of resin in the fiber to be dyed. The dyeing temperature is usually in the range of 60 to 180°C, and preferably in the range of 80 to 160°C.
前記染色工程において、染色圧力は被染色繊維の樹脂の種類によって主として決定される。前記染色圧力は、通常は約７．４乃至４０．０ＭＰａの範囲であり、好ましくは２０乃至３０ＭＰａである。
In the dyeing process, the dyeing pressure is mainly determined by the type of resin in the dyed fiber. The dyeing pressure is usually in the range of about 7.4 to 40.0 MPa, and preferably 20 to 30 MPa.
前記染色工程における染色時間は、被染色繊維の樹脂の種類及び染色温度によって決定される。前記染色時間は、通常は約１０乃至１２０分間、好ましくは３０乃至９０分間である。
The dyeing time in the dyeing process is determined by the type of resin in the dyed fiber and the dyeing temperature. The dyeing time is usually about 10 to 120 minutes, preferably 30 to 90 minutes.
前記染色工程において、前記繊維に対する前記染料の濃度は、被染色繊維の種類と加工状態に依存する。前記被染色繊維が繊維状である場合、前記繊維に対する前記染料の濃度は、０．１乃至６．０％ｏ．ｍ．ｆ．（ｏｎ ｔｈｅ ｍａｓｓ ｏｆ ｆｉｂｅｒ）、好ましくは０．１乃至４．０％ｏ．ｍ．ｆ．である。
In the dyeing process, the concentration of the dye relative to the fiber depends on the type and processing state of the fiber to be dyed. When the fiber to be dyed is fibrous, the concentration of the dye relative to the fiber is 0.1 to 6.0% o.m.f. (on the mass of fiber), preferably 0.1 to 4.0% o.m.f.
本発明の染色方法において、浴比（被染色物：二酸化炭素の質量比）は、被染色物の種類と加工状態に依存する。前記浴比は、通常は１：２乃至１：１００、好ましくは１：５乃至１：７５である。被染色物が適当なチーズに巻かれた布の場合、本発明の染色方法において、浴比は比較的低く、例えば、１：２乃至１：５である。
In the dyeing method of the present invention, the bath ratio (mass ratio of material to be dyed: carbon dioxide) depends on the type of material to be dyed and the processing state. The bath ratio is usually 1:2 to 1:100, preferably 1:5 to 1:75. When the material to be dyed is a cloth wrapped in a suitable cheese, the bath ratio in the dyeing method of the present invention is relatively low, for example, 1:2 to 1:5.
