Description
本発明はポリエステル繊維の染色方法に関するものであり、更に詳しくは、ポリエステル繊維を濃色に、且つ効率良く染色することが可能なポリエステル繊維の染色方法に関するものである。 The present invention relates to a method for dyeing polyester fibers, and more particularly, to a method for dyeing polyester fibers capable of dyeing polyester fibers darkly and efficiently.
ポリエステル繊維の染色加工は、水を大量に使用し、しかも染色後に未着染料や染色助剤などが廃水となって大量に排出されるので、水質汚濁の原因となり、これの浄化が企業の大きな負担となりはじめている。 Polyester fiber dyeing uses a large amount of water, and after dyeing, unattached dyes and dyeing assistants are discharged as waste water and discharged in large quantities. It is starting to become a burden.
このような問題を解決するため、最近、廃液をほとんど出さずにポリエステル繊維を効率よく染色する方法として、超臨界二酸化炭素中で染色を行う方法が提案されている。 In order to solve such problems, recently, a method of dyeing in supercritical carbon dioxide has been proposed as a method of efficiently dyeing polyester fibers with little waste liquid.
例えば、特開平５−１３２８８０号公報には、分散染料を用いて疎水性繊維、例えば、ポリエステル、ナイロン、ポリオレフィン等の繊維を高濃度で染色する方法が開示されている。 For example, Japanese Patent Application Laid-Open No. 5-132880 discloses a method of dyeing hydrophobic fibers such as polyester, nylon, polyolefin and the like with a high concentration using a disperse dye.
さらに、特開２００２−３７１４８３号公報、特開２００２−３６３８７０号公報には、セルロース繊維を超臨界二酸化炭素中にて染色する方法が開示されているが、該方法を採用した場合、高温度では染料が分解し鮮明な染色ができないし、一方、低圧では染料の溶解度が不十分であるため、実質的に濃度の高い染色物が得られないという問題があった。
本発明の目的は、上記従来技術の有する問題点を解決し、特に、ポリエステル繊維を濃色に、且つ効率良く染色することが可能なポリエステル繊維の染色方法を提供することにある。 An object of the present invention is to solve the above-mentioned problems of the prior art, and in particular, to provide a method for dyeing polyester fibers capable of dyeing polyester fibers darkly and efficiently.
本発明者らは上記目的を達成するために鋭意検討した結果、超臨界二酸化炭素による染色に際し、極性有機溶媒と水との混合液を共溶媒として併用するとき、所望の濃度が発現することを究明し、本発明に到達した。 As a result of intensive studies to achieve the above object, the present inventors have found that, when dyeing with supercritical carbon dioxide, when using a mixture of a polar organic solvent and water as a cosolvent, a desired concentration is expressed. As a result, the present invention was reached.
かくして本発明によれば、超臨界二酸化炭素流体中で、ポリエステル繊維を染色するに際し、該超臨界二酸化炭素流体に、メタノール、エタノール、プロパノール、イソプロピルアルコール、ブタノール、ベンジルアルコール、アセトン、アセトフェノン、Ｎ−メチル−２−ピロリドン、メチルエチルケトン、ジメチルスルフォキシド、ジメチルフォルムアミド、エチレングリコール、アセトニトリルからなる群から選ばれた少なくとも一種の極性有機溶媒と水との混合液を０．０１〜１０モル％添加することを特徴とするポリエステル繊維の染色方法が提供される。 Thus, according to the present invention, when polyester fibers are dyed in a supercritical carbon dioxide fluid, methanol, ethanol, propanol, isopropyl alcohol, butanol, benzyl alcohol, acetone, acetophenone, N- 0.01 to 10 mol% of a mixed liquid of at least one polar organic solvent selected from the group consisting of methyl-2-pyrrolidone, methyl ethyl ketone, dimethyl sulfoxide, dimethyl formamide, ethylene glycol, and acetonitrile and water is added. A method for dyeing polyester fibers is provided.
本発明によれば、廃液をほとんど出さずに、ポリエステル繊維を濃色に、且つ効率良く染色することが可能なポリエステル繊維の染色方法が提供されるので、ポリエステル繊維の染色加工に広く使用することができる。 According to the present invention, a polyester fiber dyeing method capable of efficiently dyeing polyester fibers in a dark color with little waste liquid is provided, so that it can be widely used for dyeing polyester fibers. Can do.
以下、本発明を詳細に説明する。本発明で使用するポリエステル繊維とは、エチレンテレフタレートを主たる繰り返し成分とするものが好ましく、繰り返し単位の９０モル％以上がエチレンテレフタレートであるものがより好ましく、さらに繰り返し単位の９５モル％以上がエチレンテレフタレートであるものが好ましい。 Hereinafter, the present invention will be described in detail. The polyester fiber used in the present invention is preferably one having ethylene terephthalate as the main repeating component, more preferably 90 mol% or more of the repeating unit is ethylene terephthalate, and more preferably 95 mol% or more of the repeating unit of ethylene terephthalate. Are preferred.
尚、該ポリエステルには、少量の共重合成分が共重合されていても良く、具体的には、イソフタル酸、５−ナトリウムスルホイソフタル酸、ナフタレンジカルボン酸などの芳香族ジカルボン酸、アジピン酸、セバシン酸などの脂肪族ジカルボン酸、テトラメチレングリコール、ヘキサメチレングリコールなどの脂肪族ジオールなどが例示される。更に該ポリエステル繊維は、本範囲の目的を損なわない範囲内で、安定剤、酸化防止剤、帯電防止剤、蛍光増白剤、触媒、着色剤などを添加したものでもよい。 The polyester may be copolymerized with a small amount of a copolymer component, specifically, aromatic dicarboxylic acids such as isophthalic acid, 5-sodium sulfoisophthalic acid, naphthalenedicarboxylic acid, adipic acid, sebacin. Examples include aliphatic dicarboxylic acids such as acids, and aliphatic diols such as tetramethylene glycol and hexamethylene glycol. Further, the polyester fiber may be added with a stabilizer, an antioxidant, an antistatic agent, a fluorescent brightening agent, a catalyst, a colorant, and the like within a range not impairing the purpose of this range.
本発明においては、上記ポリエステル繊維を、超臨界二酸化炭素流体中で染色するに際し、該超臨界二酸化炭素流体に、メタノール、エタノール、プロパノール、イソプロピルアルコール、ブタノール、ベンジルアルコール、アセトン、アセトフェノン、Ｎ−メチル−２−ピロリドン、メチルエチルケトン、ジメチルスルフォキシド、ジメチルフォルムアミド、エチレングリコール、アセトニトリルからなる群から選ばれた少なくとも一種の極性有機溶媒と水との混合液を共溶媒として添加する。 In the present invention, when the polyester fiber is dyed in a supercritical carbon dioxide fluid, methanol, ethanol, propanol, isopropyl alcohol, butanol, benzyl alcohol, acetone, acetophenone, N-methyl is added to the supercritical carbon dioxide fluid. A mixture of at least one polar organic solvent selected from the group consisting of -2-pyrrolidone, methyl ethyl ketone, dimethyl sulfoxide, dimethyl formamide, ethylene glycol, and acetonitrile and water is added as a co-solvent.
ここで、添加する混合液の量は０．０１〜１０モル％、好ましくは０．１〜５モル％である。該添加量が０．０１モル％より少ない場合は、本発明の効果が充分に発現せず、一方、該添加量が１０モル％を越える場合は、染色性が低下するばかりでなく、処理後の繊維布帛などに溶媒が残存し、溶媒除去の後処理が必要となるので好ましくない。 Here, the amount of the mixed solution to be added is 0.01 to 10 mol%, preferably 0.1 to 5 mol%. When the added amount is less than 0.01 mol%, the effect of the present invention is not sufficiently exhibited. On the other hand, when the added amount exceeds 10 mol%, not only the dyeability is lowered but also after the treatment. This is not preferable because the solvent remains in the fiber fabric and the like, and a post-treatment after removing the solvent is required.
次いで、本発明においては、上記混合液を添加した超臨界二酸化炭素流体中に染料を添加し、７〜３５ＭＰａの圧力、及び４０〜２００℃の温度で染色する。 Next, in the present invention, a dye is added to the supercritical carbon dioxide fluid to which the above mixed solution is added, and dyeing is performed at a pressure of 7 to 35 MPa and a temperature of 40 to 200 ° C.
ここで用いる染料としては、水に難溶か又は不溶性の分散染料が使用可能で、その例としては、ニトロ染料、メチン染料、キノリン染料、アミノナフトキノン染料、クマリン染料、好ましくはアントラキノン染料、トリシアノビニル染料、アゾ染料、ジニトロジフェニルアミン、など公知の分散染料が使用できる。 As the dye used here, disperse dyes that are sparingly soluble or insoluble in water can be used. Examples thereof include nitro dyes, methine dyes, quinoline dyes, aminonaphthoquinone dyes, coumarin dyes, preferably anthraquinone dyes, tricyano dyes. Known disperse dyes such as vinyl dyes, azo dyes and dinitrodiphenylamine can be used.
染料の添加量は、合成繊維の重量に対し０．０１〜１０重量部（％ｏｗｆ）であることが好ましい。該添加量が０．０１％ｏｗｆよりも少ない場合には所望の色相に染色できない場合がある。一方、該添加量が２０％ｏｗｆを超える場合には超臨界処理機械の中に染料が多く残存し、洗浄に手間がかかる。 The addition amount of the dye is preferably 0.01 to 10 parts by weight (% owf) with respect to the weight of the synthetic fiber. If the amount added is less than 0.01% owf, the desired hue may not be dyed. On the other hand, when the addition amount exceeds 20% owf, a large amount of dye remains in the supercritical processing machine, and it takes time and effort for cleaning.
本発明の染色方法における超臨界二酸化炭素流体中での圧力は、７〜３５ＭＰａであることが好ましい。該圧力が７ＭＰａ未満の場合は、染料が繊維に充分に染着されず、本発明の効果が発現しにくくなる。一方、圧力が３５ＭＰａを超えると装置が大掛かりになって、加工に要するエネルギーも多くなってしまう。 The pressure in the supercritical carbon dioxide fluid in the dyeing method of the present invention is preferably 7 to 35 MPa. When the pressure is less than 7 MPa, the dye is not sufficiently dyed on the fiber, and the effect of the present invention is hardly exhibited. On the other hand, if the pressure exceeds 35 MPa, the apparatus becomes large and the energy required for processing increases.
また、本発明の染色方法における温度は４０〜２００℃が好ましい。該温度が４０℃未満の場合は染色時間が長くなり過ぎ、本発明の効果が発現しにくくなる。一方、染色温度が２００℃を超えると、繊維や染料が劣化する場合があり、染色に要するエネルギーも大きくなる。より好適には１５０℃以下で良い。 The temperature in the dyeing method of the present invention is preferably 40 to 200 ° C. When the temperature is lower than 40 ° C., the dyeing time becomes too long, and the effect of the present invention is hardly exhibited. On the other hand, if the dyeing temperature exceeds 200 ° C., fibers and dyes may deteriorate, and the energy required for dyeing also increases. More preferably, it may be 150 ° C. or lower.
染色に要する時間は、使用する染料の種類によっても異なるが、通常５〜９０分が好ましい。９０分を超えると作業効率の点から好ましくない場合が多い。より好適には６０分以内が良い。一方、５分未満の時間では、所望の色相が得られない場合が多いし、繊維への付着ムラも発生しやすくなる。より好適には１５分以上が良い。 The time required for dyeing varies depending on the type of dye used, but is usually preferably from 5 to 90 minutes. If it exceeds 90 minutes, it is often not preferable from the viewpoint of work efficiency. More preferably, it is within 60 minutes. On the other hand, in a time of less than 5 minutes, a desired hue is often not obtained, and uneven adhesion to the fiber is likely to occur. More preferably, 15 minutes or more is good.
また、染色浴はオートクレーブを用いることが好ましく、浴比は１：５〜１００が好ましい。 The dyeing bath is preferably an autoclave, and the bath ratio is preferably 1: 5 to 100.
以下、実施例を挙げて本発明の構成および効果をさらに詳細に説明する。尚、実施例における各物性は以下の方法により求めたものである。 Hereinafter, an example is given and the composition and effect of the present invention are explained in detail. In addition, each physical property in an Example is calculated | required with the following method.
