Description
本発明は合成繊維の処理方法に関するものであり、更に詳しくは、合成繊維に、各種機能を付与することが可能な合成繊維の処理方法に関するものである。 The present invention relates to a synthetic fiber treatment method, and more particularly, to a synthetic fiber treatment method capable of imparting various functions to a synthetic fiber.
繊維或いは繊維布帛への機能付与加工は、精錬後または染色後に、水または溶剤を大量に使用して、含浸法（Ｄｉｐ法）、コーティング法などによって、機能剤を付与させる方法がこれまで一般に採用されてきた。この場合、機能剤は繊維の表面に付着するために、大量の機能剤が必要となり、コスト高となる上、耐久性の劣るものしか得られないという問題があった。 As a function-imparting process for fibers or fiber fabrics, a method in which a functional agent is imparted by an impregnation method (Dip method) or a coating method using a large amount of water or a solvent after refining or after dyeing has been generally used. It has been. In this case, since the functional agent adheres to the surface of the fiber, a large amount of the functional agent is required, resulting in a problem that the cost is high and only inferior durability is obtained.
また、このような方法においては、加工後に未使用の機能剤や助剤などが廃液に混じって大量に排出され、水質汚濁、大気汚染の原因となり、これの浄化が企業の大きな負担となりはじめている。 Also, in such a method, unused functional agents and auxiliaries etc. are mixed with waste liquid after processing and discharged in large quantities, causing water pollution and air pollution, and purification of this is beginning to become a heavy burden on companies .
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機能剤を効率よく付与する方法として、超臨界二酸化炭素中で処理を行う方法が提案されている。 In order to solve such problems, recently, a method of treating in supercritical carbon dioxide has been proposed as a method for efficiently applying a functional agent with little waste liquid.
例えば、特開平５−２４７８４１号公報には、蛍光漂白剤を用いて疎水性繊維を漂白する方法が開示されており、また、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, JP-A-5-247841 discloses a method of bleaching hydrophobic fibers using a fluorescent bleaching agent, and JP-A-5-132880 discloses hydrophobicity using a disperse dye. A method for dyeing fibers such as polyester, nylon, polyolefin and the like at a high concentration is disclosed.
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、該方法を例えばアラミド繊維へ適用しようとすると、繊維自身の分子構造が非常に緻密であるため、機能剤を繊維内部にまで充分浸透させることは非常に困難であった。
本発明の目的は、上記従来技術の有する問題点を解決し、アラミド繊維など、繊維の分子構造が非常に緻密な繊維であっても、機能剤を充分に浸透させることが可能な超臨界二酸化炭素流体処理方法を提供することにある。 The object of the present invention is to solve the above-mentioned problems of the prior art, and supercritical dioxide capable of sufficiently penetrating a functional agent even if the molecular structure of the fiber is very dense, such as an aramid fiber. The object is to provide a carbon fluid treatment method.
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、超臨界二酸化炭素とその共溶媒とを併用し、非水系で処理するとき、所望の機能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-mentioned object, the present inventors have determined that a desired function is exhibited when processing is performed in a non-aqueous system using a combination of supercritical carbon dioxide and a co-solvent thereof, and the present invention. Reached.
かくして本発明によれば、超臨界二酸化炭素流体中で、合成繊維に機能剤を付与するに際し、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を０．０１〜１０モル％添加し、次いで、機能剤をアラミド繊維に対し０．０１〜２０重量部添加した後、１０〜４５ＭＰａの圧力、及び１００〜２８０℃の温度で処理することを特徴とする合成繊維の処理方法が提供される。 Thus, according to the present invention, when a functional agent is added to a synthetic fiber in a supercritical carbon dioxide fluid, methanol, ethanol, propanol, isopropyl alcohol, butanol, benzyl alcohol, acetone, acetophenone is added to the supercritical carbon dioxide fluid. At least one polar organic solvent selected from the group consisting of N-methyl-2-pyrrolidone, methyl ethyl ketone, dimethyl sulfoxide, dimethyl formamide, ethylene glycol, acetonitrile, There is provided a method for treating synthetic fibers, characterized in that, after adding 0.01 to 20 parts by weight of a functional agent to aramid fibers, treatment is performed at a pressure of 10 to 45 MPa and a temperature of 100 to 280 ° C.
本発明によれば、廃液をほとんど出さずに、機能剤を効率よく繊維に付与することが可能な合成繊維の処理方法が提供されるので、各種機能付与加工に好適に使用することができる。 According to the present invention, there is provided a method for treating a synthetic fiber that can efficiently impart a functional agent to a fiber with almost no waste liquid, so that it can be suitably used for various function imparting processes.
以下、本発明を詳細に説明する。本発明で使用する合成繊維とは、機能付与剤を付着させることが可能な、ポリエステル繊維、ポリプロピレン繊維、アセテート繊維、ポリ塩化ビニル繊維、或いはアラミド繊維などを主成分とする繊維を言い、これらが糸条、織物、編物、不織布などの繊維構造物とされていても良い。中でも、合成繊維が、繊維の分子構造が非常に緻密なアラミド繊維である場合に本発明の効果が顕著に発現する。 Hereinafter, the present invention will be described in detail. The synthetic fiber used in the present invention refers to a fiber mainly composed of polyester fiber, polypropylene fiber, acetate fiber, polyvinyl chloride fiber, or aramid fiber to which a function-imparting agent can be attached. It may be a fiber structure such as a yarn, a woven fabric, a knitted fabric, or a non-woven fabric. In particular, the effects of the present invention are remarkably exhibited when the synthetic fiber is an aramid fiber having a very dense molecular structure.
ここにいうアラミド繊維の代表例としては、ポリパラアミノベンズアミド、ポリパラフェニレンテレフタルアミド、ポリパラアミノベンズヒドラジドテレフタルアミド、ポリテレフタル酸ヒドラジド、ポリメタフェニレンイソフタルアミド等、もしくはこれらの共重合体からなる繊維を挙げることができる。特に、優れたＬＯＩ値を有するポリメタフェニレンイソフタルアミドを用いることが有用であるが、織物強度を向上させる目的でパラ系のアラミド繊維、すなわち、ポリパラフェニレンテレフタルアミド、あるいは、これに第３成分を共重合した繊維を混合させることがより好ましい。ポリパラフェニレンテレフタルアミド共重合体の一例としては、下記式に示すコポリパラフェニレン・３，４’オキシジフェニレンテレフタルアミドを挙げることができる。 Representative examples of the aramid fibers mentioned here include polyparaaminobenzamide, polyparaphenylene terephthalamide, polyparaaminobenzhydrazide terephthalamide, polyterephthalic acid hydrazide, polymetaphenylene isophthalamide, and the like, or fibers made of copolymers thereof. Can be mentioned. In particular, it is useful to use polymetaphenylene isophthalamide having an excellent LOI value, but for the purpose of improving fabric strength, para-aramid fiber, that is, polyparaphenylene terephthalamide, or a third component thereof is used. It is more preferable to mix fibers obtained by copolymerizing. An example of the polyparaphenylene terephthalamide copolymer is copolyparaphenylene 3,4'oxydiphenylene terephthalamide represented by the following formula.
ここで、添加する極性有機溶媒の量は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、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 polar organic solvent to be added is 0.01 to 10 mol%, preferably 0.1 to 5 mol%. When the addition amount is less than 0.01 mol%, the effect of the present invention is not sufficiently exhibited. On the other hand, when the addition amount exceeds 10 mol%, the solvent remains in the treated fiber fabric or the like. This is not preferable because a post-treatment after removing the solvent is required.
次いで、本発明においては、上記極性有機溶媒を添加した超臨界二酸化炭素流体中に機能剤を添加し、１０〜４５ＭＰａの圧力、及び１００〜２８０℃の温度で処理する。 Next, in the present invention, a functional agent is added to the supercritical carbon dioxide fluid to which the polar organic solvent is added, and the treatment is performed at a pressure of 10 to 45 MPa and a temperature of 100 to 280 ° C.
ここで、機能剤とは、撥水剤、撥油剤、防炎剤、抗菌剤、防臭剤、制電防止剤、紫外線吸収剤、酸化防止剤、柔軟剤、金属錯体など、合成繊維に各種機能を付与できる剤を言い、染料や顔料などの着色機能を除くものである。 Here, the functional agent is a water repellent, oil repellent, flame retardant, antibacterial agent, deodorant, antistatic agent, ultraviolet absorber, antioxidant, softener, metal complex, etc. Is an agent capable of imparting a coloring function such as dyes and pigments.
該機能剤の添加量は、合成繊維の重量に対し０．０１〜２０重量部である必要がある。該添加量が０．０１重量部よりも少ない場合には高い機能性付与ができず目的とする効果が出ない。一方、該機能剤の添加量が２０重量部を超える場合には超臨界処理機械の中に機能剤が多く残存し、洗浄に手間がかかる。 The addition amount of this functional agent needs to be 0.01-20 weight part with respect to the weight of a synthetic fiber. When the addition amount is less than 0.01 parts by weight, high functionality cannot be imparted and the intended effect does not appear. On the other hand, when the added amount of the functional agent exceeds 20 parts by weight, a large amount of the functional agent remains in the supercritical processing machine, and it takes time for cleaning.
本発明における超臨界二酸化炭素流体中での処理圧力は、１０〜４５ＭＰａである。該圧力が１０ＭＰａ未満の場合は、機能剤が繊維に充分に付与されず、本発明の効果が発現しにくくなる。一方、処理圧力が４５ＭＰａ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。また、この際の処理温度は１００〜２８０℃である。処理温度が１００℃未満の場合は機能剤が繊維に充分に付与されず、本発明の効果が発現しにくくなる。一方、処理温度が２８０℃を超えると、繊維や機能剤が劣化する場合があり、加工に要するエネルギーも大きくなる。 The processing pressure in the supercritical carbon dioxide fluid in the present invention is 10 to 45 MPa. When the pressure is less than 10 MPa, the functional agent is not sufficiently applied to the fiber, and the effect of the present invention is hardly exhibited. On the other hand, if the processing pressure exceeds 45 MPa, the apparatus becomes large and the energy required for processing increases. Moreover, the process temperature in this case is 100-280 degreeC. When processing temperature is less than 100 degreeC, a functional agent is not fully provided to a fiber and the effect of this invention becomes difficult to express. On the other hand, when the processing temperature exceeds 280 ° C., the fiber and the functional agent may be deteriorated, and the energy required for processing also increases.
機能剤の付与に要する時間は、使用する機能剤の種類によっても異なるが、通常５〜９０分である。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分以内である。一方、５分未満の時間では、所望の機能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分以上である。 The time required for applying the functional agent varies depending on the type of the functional agent used, but is usually 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, when the time is less than 5 minutes, the desired function is often not obtained, and uneven adhesion to the fiber is likely to occur. More preferably, it is 15 minutes or more.
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.
