かかる変色を隠蔽するために芳香族ポリアミド繊維は、
他の繊維で被覆してなる被覆糸として使用したり、また
ロープおよび布帛物にした後に、樹脂加工などの保護加
工を施して使用されているのが実情である。Aromatic polyamide fiber in order to hide such discoloration,
Actually, it is used as a coated yarn formed by coating with other fibers, or after being made into a rope or a fabric, it is subjected to a protective treatment such as resin treatment before use.
［発明が解決しようとする問題点］ 芳香族ポリアミド繊維のかかる変色欠点は商品開発に於
て大きな問題である。[Problems to be Solved by the Invention] Such a discoloration defect of the aromatic polyamide fiber is a major problem in product development.
すなわち、該繊維が露出した商品を製造すると、消費者

変色し、初期とは異なった色となり、用途によっては、
その時点で実用できないことになる。特に衣料分野およ
び靴、鞄などのファッション性のある商品においては、
かかる欠点は致命的である。That is, when a product in which the fibers are exposed is manufactured, the color of the product gradually changes until it reaches the hands of the consumer or while the product is in use, resulting in a color different from the initial color.
It will not be practical at that time. Especially in the field of clothing and fashionable products such as shoes and bags,
Such drawbacks are fatal.
また、染色して変色を防止する方法が近年多く提案され
ているが、このような方法は染色に多くの手数を要する
ばかりか、耐光堅牢度が悪いなどの欠点があった。In addition, many methods of dyeing to prevent discoloration have been proposed in recent years, but such methods have drawbacks such as not only a large number of dyeing steps but also poor light fastness.
本発明は、かかる問題点を解消し、紫外線で変色しない
芳香族ポリアミド繊維を提供するものであり、本発明に
よれば簡単な方法で長時間の太陽光線曝露に耐え得る着
色芳香族ポリアミド繊維を提供することができる。The present invention solves the above problems and provides an aromatic polyamide fiber that does not discolor with ultraviolet rays. According to the present invention, a colored aromatic polyamide fiber that can withstand long-term exposure to sunlight is provided by a simple method. Can be provided.
［問題点を解決するための手段］ 本発明はかかる目的を達成するために次のような構成を
採用するものである。すなわち、 （１） 芳香族ポリアミド系成形品がポリエチレンイミ
ンにより茶系色に着色されていることを特徴とする着色
芳香族ポリアミド繊維。[Means for Solving Problems] The present invention adopts the following configuration in order to achieve such an object. That is, (1) A colored aromatic polyamide fiber characterized in that an aromatic polyamide-based molded product is colored in a brown color with polyethyleneimine.
（２） 芳香族ポリアミド系繊維にポリエチレンイミン
を付着せしめた後、100℃以上の熱処理を施して茶系色
に発色させることを特徴とする着色芳香族ポリアミド繊
維の製造方法。(2) A method for producing a colored aromatic polyamide fiber, which comprises depositing polyethyleneimine on the aromatic polyamide fiber and then subjecting it to heat treatment at 100 ° C. or higher to develop a brown color.
（３） 前記ポリエチレンイミン系化合物が、ポリエチ
レンイミン系化合物を0.5〜10重量％含有する処理液に
より付着処理される特許請求の範囲第（２）項記載の着
色芳香族ポリアミド繊維の製造方法。(3) The method for producing a colored aromatic polyamide fiber according to claim (2), wherein the polyethyleneimine-based compound is attached by a treatment liquid containing 0.5 to 10% by weight of the polyethyleneimine-based compound.
（４） 前記熱処理が、温度130〜250℃である特許請求
の範囲第（２）項記載の着色芳香族ポリアミド繊維の製
造方法である。(4) The method for producing a colored aromatic polyamide fiber according to claim (2), wherein the heat treatment is performed at a temperature of 130 to 250 ° C.
ポリエチレンイミンは次のような分岐構造を有する。Polyethyleneimine has the following branched structure.
該化合物の第１級アミン基が芳香族ポリアミド繊維のカ
ルボキシル基と反応してアミド結合をつくり、ポリエチ
レンイミンの表面被膜が形成されるものと考えられる。 It is considered that the primary amine group of the compound reacts with the carboxyl group of the aromatic polyamide fiber to form an amide bond to form a surface coating of polyethyleneimine.
なお、ポリエチレンイミンとは、たとえばエチレンオキ
シドやプロピレンオキシドなどのアルキレンオキシド付
加物も含むものである。The polyethyleneimine also includes alkylene oxide adducts such as ethylene oxide and propylene oxide.
かかるポリエチレンイミンの中でも、発色性と接着性に
優れた性能を発揮するものとしては、活性化水素を有す
る窒素が多い化合物であり、さらに重合度が約100以上
のポリマーが好ましく、たとえば、エチレンイミン単体
およびテロマー（低重合度）は、発色性に劣り、接着性
も弱い傾向がある。Among such polyethyleneimines, those exhibiting excellent performance in color development and adhesiveness are compounds having a large amount of nitrogen having activated hydrogen, and a polymer having a degree of polymerization of about 100 or more is preferable, for example, ethyleneimine. A simple substance and a telomer (low degree of polymerization) tend to have poor color developability and weak adhesiveness.
かかるポリエチレンイミンは0.5〜10重量％、好ましく
は３〜６重量％の範囲で含有する処理液を用いる。0.5
％以下では淡色にしか染色できず、自然老化色の茶系色
（褐色）に着色する効果が小さく、また10％以上では繊
維が硬くなる傾向がある。A treatment liquid containing 0.5 to 10% by weight, preferably 3 to 6% by weight of such polyethyleneimine is used. 0.5
% Or less, only a light color can be dyed, and the effect of coloring to a brown color (brown) which is a natural aging color is small, and if 10% or more, the fiber tends to be hard.
ポリエチレンイミンは約130℃から接着力と発色効果と
の相乗効果を惹起し、約250℃で発色性はほぼ飽和状態
に達する。Polyethyleneimine induces a synergistic effect between the adhesive strength and the coloring effect at about 130 ° C, and the coloring property reaches a saturated state at about 250 ° C.
接着力と発色度は、芳香族ポリアミド繊維をポリエチレ
ンイミン水溶液に浸漬後の熱処理条件に依存し、単に風
乾しただけでは接着力も発色性も満足には達成されない
特徴がある。The adhesive strength and the degree of color development depend on the heat treatment conditions after the aromatic polyamide fiber is immersed in the polyethyleneimine aqueous solution, and there is a characteristic that the adhesive strength and the color developability cannot be satisfactorily achieved only by air-drying.
接着力の測定は、該繊維から成る織物をポリエチレンイ
ミンの水溶液に浸漬、熱処理後、沸騰水中で洗い、その
後の付着ポリエチレンイミン量を塩酸消費量として求め
た。The adhesive strength was measured by immersing a woven fabric composed of the fibers in an aqueous solution of polyethyleneimine, heat-treating it, and then washing it in boiling water, and then determining the amount of adhered polyethyleneimine as the consumption of hydrochloric acid.
固着量は熱処理温度の上昇と共に増すが、この固着量が
接着力と相関関係があり、固着量が多い程接着力は高く
なる。The amount of sticking increases as the heat treatment temperature rises, but this amount of sticking has a correlation with the adhesive force, and the larger the amount of sticking, the higher the adhesive force.
芳香族ポリアミド繊維は耐熱性に優れ、短時間なら300
℃程度まで安定であり、かなりの高熱処理に対しても有
効に処理することができる。Aromatic polyamide fiber has excellent heat resistance and 300 for a short time
It is stable up to about 0 ° C, and can be effectively treated even with a considerably high heat treatment.
