The meta-type wholly aromatic polyamide fiber can be produced, for example, by the following method.
The polymerization method of the meta-type wholly aromatic polyamide polymer is not particularly limited. For example, the solution weight described in Japanese Patent Publication No. 35-14399, US Pat. No. 3,360,595, Japanese Patent Publication No. 47-10863, etc. A combination method or an interfacial polymerization method may be used.
紡糸溶液としては、とくに限定する必要はないが、上記溶液重合や界面重合などで得られた、芳香族コポリアミドポリマーを含むアミド系溶媒溶液を用いても良いし、上記重合溶液から該ポリマーを単離し、これをアミド系溶媒に溶解したものを用いてもよい。 The spinning solution is not particularly limited, but an amide solvent solution containing an aromatic copolyamide polymer obtained by the above solution polymerization or interfacial polymerization may be used, or the polymer may be removed from the polymerization solution. You may use what was isolated and melt | dissolved in the amide-type solvent.
ここで用いられるアミド系溶媒としては、Ｎ，Ｎ−ジメチルホルムアミド、Ｎ，Ｎ−ジメチルアセトアミド、Ｎ−メチル−２−ピロリドン、ジメチルスルホキシドなどを例示することができるが、とくにＮ，Ｎ−ジメチルアセトアミドが好ましい。 Examples of the amide solvent used here include N, N-dimethylformamide, N, N-dimethylacetamide, N-methyl-2-pyrrolidone, dimethyl sulfoxide and the like, and in particular, N, N-dimethylacetamide. Is preferred.
上記の通り得られた共重合芳香族ポリアミドポリマー溶液は、さらにアルカリ金属塩またはアルカリ土類金属塩を含むことにより安定化され、より高濃度、低温での使用が可能となり好ましい。好ましくはアルカリ金属塩およびアルカリ土類金属塩がポリマー溶液の全重量に対して１重量％以下、より好ましくは０．１重量％以下である。 The copolymerized aromatic polyamide polymer solution obtained as described above is preferably stabilized by containing an alkali metal salt or an alkaline earth metal salt, and can be used at a higher concentration and at a lower temperature. Preferably, the alkali metal salt and alkaline earth metal salt are 1% by weight or less, more preferably 0.1% by weight or less, based on the total weight of the polymer solution.
紡糸・凝固工程においては、上記で得られた紡糸液（メタ型全芳香族ポリアミド重合体溶液）を凝固液中に紡出して凝固させる。 In the spinning / coagulation step, the spinning solution (meta-type wholly aromatic polyamide polymer solution) obtained above is spun into a coagulating solution and coagulated.
紡糸装置としては特に限定されるものではなく、従来公知の湿式紡糸装置を使用することができる。また、安定して湿式紡糸できるものであれば、紡糸口金の紡糸孔数、配列状態、孔形状等は特に制限する必要はなく、例えば、孔数が１０００〜３００００個、紡糸孔径が０．０５〜０．２ｍｍのスフ用の多ホール紡糸口金等を用いてもよい。
また、紡糸口金から紡出する際の紡糸液（メタ型全芳香族ポリアミド重合体溶液）の温度は、２０〜９０℃の範囲が適当である。
The spinning device is not particularly limited, and a conventionally known wet spinning device can be used. Further, the number of spinning holes, the arrangement state, the hole shape and the like of the spinneret are not particularly limited as long as they can be stably wet-spun. For example, the number of holes is 1,000 to 30,000, and the spinning hole diameter is 0.05. A multi-hole spinneret for ˜0.2 mm sufu may be used.
The temperature of the spinning solution (meta-type wholly aromatic polyamide polymer solution) when spinning from the spinneret is suitably in the range of 20 to 90 ° C.
繊維を得るために用いる凝固浴としては、実質的に無機塩を含まない、アミド系溶媒、好ましくはＮＭＰの濃度が４５〜６０質量％の水溶液を、浴液の温度１０〜５０℃の範囲で用いる。アミド系溶媒（好ましくはＮＭＰ）の濃度が４５質量％未満ではスキンが厚い構造となってしまい、洗浄工程における洗浄効率が低下し、繊維の残存溶媒量を低減させることが困難となる。一方、アミド系溶媒（好ましくはＮＭＰ）の濃度が６０質量％を超える場合には、繊維内部に至るまで均一な凝固を行うことができず、このためやはり、繊維の残存溶媒量を低減させることが困難となる。なお、凝固浴中への繊維の浸漬時間は、０．１〜３０秒の範囲が適当である。 As a coagulation bath used for obtaining fibers, an amide solvent, which is substantially free of inorganic salts, preferably an aqueous solution having a concentration of NMP of 45 to 60% by mass within a temperature range of the bath solution of 10 to 50 ° C. Use. When the concentration of the amide solvent (preferably NMP) is less than 45% by mass, the skin has a thick structure, the cleaning efficiency in the cleaning step is lowered, and it is difficult to reduce the residual solvent amount of the fiber. On the other hand, when the concentration of the amide solvent (preferably NMP) exceeds 60% by mass, uniform coagulation cannot be performed up to the inside of the fiber, and therefore, the residual solvent amount of the fiber can be reduced. It becomes difficult. In addition, the range of 0.1-30 seconds is suitable for the immersion time of the fiber in a coagulation bath.
引続き、アミド系溶媒、好ましくはＮＭＰの濃度が４５〜６０質量％の水溶液であり、浴液の温度を１０〜５０℃の範囲とした可塑延伸浴中にて、３〜４倍の延伸倍率で延伸を行う。延伸後、１０〜３０℃のＮＭＰの濃度が２０〜４０質量％の水溶液、続いて５０〜７０℃の温水浴を通して十分に洗浄を行う。 Subsequently, it is an aqueous solution having an amide solvent, preferably an NMP concentration of 45 to 60% by mass, and a stretch ratio of 3 to 4 times in a plastic stretching bath in which the temperature of the bath liquid is in the range of 10 to 50 ° C. Stretching is performed. After stretching, the film is thoroughly washed through an aqueous solution having an NMP concentration of 20 to 40% by mass at 10 to 30 ° C. and then a hot water bath at 50 to 70 ° C.
洗浄後の繊維は、温度２７０〜２９０℃にて乾熱処理を施し、上記の結晶化度の範囲を満たすメタ型全芳香族ポリアミド繊維を得ることができる。 The washed fiber can be subjected to a dry heat treatment at a temperature of 270 to 290 ° C. to obtain a meta-type wholly aromatic polyamide fiber satisfying the above crystallinity range.

In particular, short fibers having a fiber length of 25 to 200 mm (more preferably 30 to 150 mm) are preferable in blending with other fibers. The single fiber fineness is preferably in the range of 1 to 5 dtex.

If the content of the meta-type wholly aromatic polyamide fiber is smaller than the above range, the flame retardancy may be lowered. Conversely, if the content of the para-type wholly aromatic polyamide fiber is smaller than the above range, the wear resistance may be lowered.
また、布帛の難燃性と耐摩耗性を両立させる上で、布帛を、前記混紡糸Ａと、パラ型全芳香族ポリアミド繊維からなる糸Ｂとで構成することは好ましいことである。その際、前記混紡糸Ａと前記糸Ｂとの重量比が（前者：後者）８５：１５〜９５：５の範囲内であることが好ましい。前記混紡糸Ａの含有量が該範囲よりも小さいと、布帛の難燃性が低下するおそれがある。逆に、前記糸Ｂの含有量が該範囲よりも小さいと、布帛の耐摩耗性が低下するおそれがある。 In order to achieve both the flame retardancy and wear resistance of the fabric, it is preferable that the fabric is composed of the blended yarn A and the yarn B made of para-type wholly aromatic polyamide fiber. At that time, the weight ratio of the blended yarn A and the yarn B is preferably in the range of (the former: the latter) 85:15 to 95: 5. If the content of the blended yarn A is smaller than the above range, the flame retardancy of the fabric may be reduced. On the other hand, if the content of the yarn B is smaller than the above range, the abrasion resistance of the fabric may be lowered.
前記糸Ｂは長繊維（マルチフィラメント）や紡績糸でもよいが、優れた耐摩耗性を得る上で長繊維牽切加工糸が好ましい。長繊維牽切加工糸とは、特開２００７−９２２０９号公報や特開２０１１−２６７２５号公報に記載されているような、長繊維を牽切して得られた加工糸であり、適度な伸度と強度を有している。 The yarn B may be a long fiber (multifilament) or a spun yarn, but a long fiber check thread is preferable in order to obtain excellent wear resistance.

(1) Abrasion strength of fabric JIS L1096 8.9.1. In the measurement of the wear strength defined in the A-1 method (planar method), the number of times until a hole was opened was measured using a polishing paper of paper count # 1200. More than 200 times were accepted.
［実施例１］
カーボンブラック顔料を含む単繊維繊度１．７ｄｔｅｘ、繊維長５１ｍｍのメタ型全芳香族ポリアミド繊維（帝人製、商標名「Ｔｅｉｊｉｎｃｏｎｅｘ」）と、単繊維繊度１．７ｄｔｅｘ、繊維長５１ｍｍのパラ型全芳香族ポリアミド繊維（帝人製、商標名「テクノーラ」）を用いて、メタ型全芳香族ポリアミド繊維：９０重量％、パラ型全芳香族ポリアミド繊維：１０重量％となるように、１／３４番手の紡績糸を作り、双糸合撚加工糸条（混紡糸Ａ）を得た。
[Example 1]
Meta-type wholly aromatic polyamide fiber (trade name “Teijinconex” manufactured by Teijin Limited) with a single fiber fineness of 1.7 dtex and fiber length of 51 mm, and a para-type total aroma with a single fiber fineness of 1.7 dtex and a fiber length of 51 mm 1/34 count so that the meta-type wholly aromatic polyamide fiber is 90% by weight and the para-type wholly aromatic polyamide fiber is 10% by weight, using an aromatic polyamide fiber (trade name “Technola” manufactured by Teijin) A spun yarn was made to obtain a twin yarn twisted yarn (mixed yarn A).
一方、パラ型全芳香族ポリアミド繊維（帝人製、商標名「テクノーラ」）からなる長繊維を用いて、特開２０１１−２６７２５号公報の実施例１と同様にして総繊度４４０ｄｔｅｘ長繊維牽切加工糸「ＧＴＮ」を得て糸Ｂとした。 On the other hand, using a long fiber made of para-type wholly aromatic polyamide fiber (manufactured by Teijin, trade name “Technola”), a total fineness 440 dtex long fiber check-off process in the same manner as in Example 1 of Japanese Patent Laid-Open No. 2011-26725 Yarn “GTN” was obtained and designated as yarn B.
次いで、前記混紡糸Ａと糸Ｂを経糸および緯糸に用いて、経密度５５本／２．５４ｃｍ、緯密度５２本／２．５４ｃｍの織密度で、図１に示す織物組織図の平変化組織織物を製織した。 Next, using the blended yarn A and yarn B as warps and wefts, the plane change structure of the fabric structure diagram shown in FIG. 1 at a weave density of warp density of 55 / 2.54 cm and weft density of 52 / 2.54 cm.
