Description

本発明は、アラミド繊維の染色方法に関するものであり、さらに詳しくは、アラミド繊維の液流染色を行った後の洗浄方法に関するものである。   The present invention relates to a method for dyeing aramid fibers, and more particularly to a washing method after liquid flow dyeing of aramid fibers.

アラミド繊維は、高い機械強度と耐熱性、並びに難燃性を有し、それらは特に、消防士、宇宙飛行士、及びパイロットのための服のデザインにおいて、火災又は高温と接触する事を意図した織物繊維として広く使用される。
また前記アラミド繊維は、結晶性が高く分子間結合力が強固な分子構造を有しており、そのため難染性を示し、たとえば染色できても洗濯などですぐに染料が脱落してしまうなど、従来の染色技術では着色することが難しいという問題があった。
Aramid fibers have high mechanical strength and heat resistance, as well as flame retardancy, and they are intended to come into contact with fire or high temperatures, especially in the design of clothes for firefighters, astronauts, and pilots Widely used as textile fiber.
In addition, the aramid fiber has a molecular structure with high crystallinity and a strong intermolecular bonding force, and therefore exhibits a difficult dyeing property. There is a problem that it is difficult to color with conventional dyeing techniques.

このような問題を解決する方法として、特許文献1には、カチオン系染料によってパラ系アラミド繊維を染色する場合において繊維膨潤剤(キャリアー)を用いる方法が開示されている。
しかしながら、上記従来の染色方法において、キャリアとしてベンジルアルコールを使用した場合、染色性は向上するものの、染色後のアラミド繊維布帛の難燃性が著しく低下するという問題があった。
As a method for solving such a problem, Patent Document 1 discloses a method in which a fiber swelling agent (carrier) is used when para-aramid fibers are dyed with a cationic dye.
However, in the above conventional dyeing method, when benzyl alcohol is used as a carrier, although the dyeability is improved, there is a problem that the flame retardancy of the aramid fiber fabric after dyeing is significantly reduced.

本発明者らは、上記問題を解決するために鋭意検討した結果、以下の方法により上記の課題を解決できることを見出した。すなわち本発明によれば、が提供される。   As a result of intensive studies to solve the above problems, the present inventors have found that the above problems can be solved by the following method. That is, according to the present invention, is provided.

本発明によれば、アラミド繊維を、液流染色する際に残存するキャリア剤、特にベンジルアルコールが存在することにより懸念されていた、燃焼性低下の問題が解決されたアラミド繊維を得ることができる。   According to the present invention, it is possible to obtain an aramid fiber in which the problem of a decrease in combustibility, which has been a concern due to the presence of a carrier agent, particularly benzyl alcohol, remaining when liquid-dyeing the aramid fiber is solved. .

以下に本発明を詳細に説明する。本発明は、アラミド繊維を染色する方法に関するものである。本発明で用いるアラミド繊維は、合成ポリアミド鎖を含み、鎖中ではアミド基の少なくとも85%が芳香族基に直接結合しているものである。また、本発明で用いるアラミド繊維は、編物、織物、不織布等いずれの形状で使用されても良い。さらに、アラミド繊維は単体で用いても、または、羊毛、ポリエステル、セルロース、ポリアクリロニトリル、絹等と混紡、交織、交編等して用いても差し支えない。   The present invention is described in detail below. The present invention relates to a method for dyeing aramid fibers. The aramid fiber used in the present invention includes a synthetic polyamide chain in which at least 85% of the amide groups are directly bonded to the aromatic group. Moreover, the aramid fiber used in the present invention may be used in any shape such as a knitted fabric, a woven fabric, and a nonwoven fabric. Furthermore, the aramid fiber may be used alone, or may be used by blending, knitting, knitting or the like with wool, polyester, cellulose, polyacrylonitrile, silk or the like.

本発明に用いる、キャリア剤としては、例えば、DL−β−エチルフェネチルアルコール、2−エトキシベンジルアルコール、3−クロロベンジルアルコール、2,5−ジメチルベンジルアルコール、2−ニトロベンジルアルコール、p−イソプロピルベンジルアルコール、2−メチルフェネチルアルコール、3−メチルフェネチルアルコール、4−メチルフェネチルアルコール、2−メトキシベンジルアルコール、3−ヨードベンジルアルコール、ケイ皮アルコール、p−アニシルアルコールおよびベンズヒドロールの中から選ばれる少なくとも一種であることが好ましい。   Examples of the carrier agent used in the present invention include DL-β-ethylphenethyl alcohol, 2-ethoxybenzyl alcohol, 3-chlorobenzyl alcohol, 2,5-dimethylbenzyl alcohol, 2-nitrobenzyl alcohol, p-isopropylbenzyl. Selected from alcohol, 2-methylphenethyl alcohol, 3-methylphenethyl alcohol, 4-methylphenethyl alcohol, 2-methoxybenzyl alcohol, 3-iodobenzyl alcohol, cinnamic alcohol, p-anisyl alcohol and benzhydrol At least one kind is preferred.

Moreover, it is preferable to use benzyl alcohol, especially 2, 5- dimethyl benzyl alcohol or 2-nitro benzyl alcohol from the point which improves whiteness more.

本発明においては、液流染色を行う際の洗浄条件としてキャリア剤であるベンジルアルコール残存量を低減させることが肝要である。
本発明者らは、布帛の残存ベンジルアルコール量を低減させる方法として洗浄条件の検討をしたが、アラミド繊維染色上がり布帛では残存ベンジルアルコール量が多く、十分な難燃性が得られなかった。そこで、さらに検討を進め、染色後にハイドロサルファイトとソーダ灰、界面活性剤を使用した還元洗浄処理することで、液流染色によって布帛残存ベンジルアルコール量の低減が可能となることを見出したものである。
In the present invention, it is important to reduce the residual amount of benzyl alcohol, which is a carrier agent, as a washing condition when performing liquid flow dyeing.
The present inventors examined the washing conditions as a method for reducing the amount of residual benzyl alcohol in the fabric. However, the amount of residual benzyl alcohol was large in the aramid fiber dyed fabric, and sufficient flame retardancy was not obtained. Therefore, further investigation was conducted, and it was found that the amount of benzyl alcohol remaining in the fabric can be reduced by liquid flow dyeing by reducing and washing using hydrosulfite, soda ash, and a surfactant after dyeing. is there.

アラミド繊維の染色後、還元洗浄を施す事によりアラミド繊維からベンジルアルコールを抽出するのに最も効果的な洗浄処理条件である。
また、本発明によれば、アラミド繊維自身が持つ難燃性を染色後も維持することも可能となる。しかもこの方法によれば、液流染色の特徴もそのまま生かすことができる。
This is the most effective washing treatment condition for extracting benzyl alcohol from aramid fibers by performing reduction washing after dyeing of aramid fibers.
Moreover, according to this invention, it becomes possible to maintain the flame retardance which an aramid fiber itself has after dyeing | staining. In addition, according to this method, the characteristics of liquid flow dyeing can be utilized as they are.

一方、洗浄剤濃度として高い程、キャリア剤であるベンジルアルコールの除去に最適だと考えられるが、布帛の変色性の面から十分な染色性を得られない傾向にあり、洗浄剤濃度としてハイドロサルファイト1g/l、ソーダ灰1g/l、アミラジンD1g/lが好ましいと考える。
Examples of the cleaning agent used in the present invention include reductive cleaning such as hydrosulfite, soda ash, and emulsifier. Among them, amylazine D is preferable as the emulsifier.
On the other hand, the higher the detergent concentration, the more optimal the removal of benzyl alcohol, which is a carrier agent, but there is a tendency that sufficient dyeability cannot be obtained in terms of discoloration of the fabric. Phyto 1 g / l, soda ash 1 g / l, and amylazine D 1 g / l are considered preferable.
