Detailed Description
Hereinafter, embodiments of the present invention will be described in detail. First, the fabric of the present invention includes spun yarns containing meta-type wholly aromatic polyamide fibers, modacrylic fibers, and conductive fibers.
The meta-type wholly aromatic polyamide fiber used in the present invention is a fiber composed of a polymer in which at least 85 mol% of the repeating units are m-phenylene isophthalamide. The meta-type wholly aromatic polyamide may be a copolymer containing the component 3 in an amount of less than 15 mol%.
Such a meta-type wholly aromatic polyamide can be produced by a conventionally known interfacial polymerization method, and is preferably produced by using a polymer having a polymerization degree in the range of 1.3 to 1.9dl/g as measured in an N-methyl-2-pyrrolidone solution having a concentration of 0.5g/100 ml.
The meta-type wholly aromatic polyamide may contain an alkylbenzenesulfonate. As the alkylbenzene sulfonate, preferred are compounds such as tetrabutylphosphonium hexylbenzenesulfonate, tributylbenzylphosphonium hexylbenzenesulfonate, tetraphenylphosphonium dodecylbenzenesulfonate, tributyltetradecylphosphonium dodecylbenzenesulfonate, tetrabutylphosphonium dodecylbenzenesulfonate and tributylbenzylammonium dodecylbenzenesulfonate. Among them, tetrabutylphosphonium dodecylbenzenesulfonate or tributylbenzylammonium dodecylbenzenesulfonate is particularly preferable because it is easily available, has good thermal stability, and has high solubility in N-methyl-2-pyrrolidone.
In order to obtain a sufficient dyeing property improving effect, the content of the alkylbenzene sulfonate is preferably 2.5 mol% or more, and more preferably 3.0 to 7.0 mol% with respect to the poly (m-phenylene isophthalamide).
In addition, as a method of mixing poly (m-phenylene isophthalamide) and alkylbenzene sulfonate, a method of mixing and dissolving poly (m-phenylene isophthalamide) in a solvent, and dissolving alkylbenzene sulfonate in the solvent, and the like can be used, and any of them can be used. The dope thus obtained is formed into fibers by a conventionally known method.
For the purpose of improving dyeability, discoloration and fading resistance, etc., a polymer used for a meta-type wholly aromatic polyamide fiber can be obtained by copolymerizing an aromatic diamine component or an aromatic dicarboxylic acid halide component different from the main structural unit of the repeating structure as the 3 rd component in the aromatic polyamide skeleton containing the repeating structural unit represented by the following formula (1) so as to be 1 to 10 mol% with respect to the total amount of the repeating structural units of the aromatic polyamide.
- (NH-Ar 1-NH-CO-Ar 1-CO) -. formula (1)
Here, Ar1 is a 2-valent aromatic group having a binding group other than in the meta-coordinate or parallel axis direction.
Specific examples of the aromatic diamine represented by the formulae (2) and (3) which can be copolymerized as the component 3 include p-phenylenediamine, chlorophenyldiamine, methylphenylenediamine, acetylphenylenediamine, aminoanisidine, benzidine, bis (aminophenyl) ether, bis (aminophenyl) sulfone, diaminobenzoylbenzene, and diaminoazobenzene. Specific examples of the aromatic dicarboxylic acid dichloride represented by the formulae (4) and (5) include terephthaloyl chloride, 1, 4-naphthalenedicarboxylic acid dichloride, 2, 6-naphthalenedicarboxylic acid dichloride, 4' -biphenyldicarbonyl chloride, 5-chloroisophthaloyl chloride, 5-methoxyisophthaloyl chloride, bis (chlorocarbonylphenyl) ether and the like.
H2N－Ar2－NH2The type (2)
H2N－Ar2－Y－Ar2－NH2The type (3)
XOC-Ar 3-COX, formula (4)
XOC-Ar 3-Y-Ar 3-COX, formula (5)
Here, Ar2 is a 2-valent aromatic group different from Ar1, Ar3 is a 2-valent aromatic group different from Ar1, Y is at least 1 atom or functional group selected from an oxygen atom, a sulfur atom, and an alkylene group, and X represents a halogen atom.
In addition, the meta-type wholly aromatic polyamide fiber preferably has a crystallinity of 5 to 35% in terms of good dye absorbency, less dye usage, or easy adjustment to a target color even if dyeing conditions are weak. Further, it is more preferably 15 to 25% from the viewpoint of being less likely to cause surface unevenness of the dye and having high discoloration/fading resistance and being able to secure dimensional stability necessary for practical use.
In addition, the residual solvent content of the meta-type wholly aromatic polyamide fiber is preferably 0.1 wt% or less (preferably 0.001 to 0.1 wt%) from the viewpoint of not impairing excellent flame retardancy of the meta-type wholly aromatic polyamide fiber.
The meta-type wholly aromatic polyamide fiber can be produced by the following method, and particularly, when the method described below is used, the crystallinity and the amount of the residual solvent can be adjusted to the above ranges.
The method of polymerizing the meta-type wholly aromatic polyamide polymer is not particularly limited, and for example, solution polymerization and interfacial polymerization methods described in Japanese patent publication No. 35-14399, U.S. Pat. No. 3360595, and Japanese patent publication No. 47-10863 can be used.
The spinning solution is not particularly limited, and an amide solvent solution containing an aromatic copolyamide polymer obtained by the above solution polymerization, interfacial polymerization, or the like may be used, or a solution obtained by separating the polymer from the above polymerization solution and dissolving the polymer in an amide solvent may be used.
Examples of the amide solvent used herein include N, N-dimethylformamide, N-dimethylacetamide, N-methyl-2-pyrrolidone, and dimethylsulfoxide, and N, N-dimethylacetamide amide is particularly preferable.
The copolymerized aromatic polyamide polymer solution obtained as described above is preferably stabilized by further containing an alkali metal salt or an alkaline earth metal salt, since it can be used at a higher concentration and a lower temperature. The alkali metal salt and the alkaline earth metal salt are preferably 1 wt% or less, more preferably 0.1 wt% or less, with respect to the total mass of the polymer solution.
In the spinning/coagulation step, the spinning solution (meta-type wholly aromatic polyamide polymer solution) obtained as described above is spun into a coagulation solution and coagulated.
The spinning device is not particularly limited, and a conventionally known wet spinning device can be used. Further, the number of spinning holes, arrangement state, hole shape and the like of the spinneret are not particularly limited as long as stable wet spinning is possible, and for example, a multi-hole spinneret for rayon having a number of holes of 1000 to 30000 and a spinning hole diameter of 0.05 to 0.2mm can be used.
The temperature of the spinning solution (meta-type wholly aromatic polyamide polymer solution) when spun from the spinneret is preferably in the range of 20 to 90 ℃.
As a coagulation bath for obtaining fibers, an amide solvent substantially free of inorganic salts is used at a bath temperature of 10 to 50 ℃, and an aqueous solution having a NMP concentration of 45 to 60 wt% is preferred. When the concentration of the amide solvent (preferably NMP) is less than 45 wt%, the structure becomes thick on the surface, the cleaning efficiency in the cleaning step is lowered, and it is difficult to reduce the amount of the residual solvent of the fibers. On the other hand, if the concentration of the amide solvent (preferably NMP) exceeds 60 wt%, uniform coagulation cannot be performed until the inside of the fibers, and therefore, it is still difficult to reduce the amount of the residual solvent of the fibers. The immersion time of the fiber in the coagulation bath is preferably in the range of 0.1 to 30 seconds.
Then, the fiber is stretched at a stretching ratio of 3 to 4 times in a plastic stretching bath in which the temperature of the bath is in the range of 10 to 50 ℃ in an amide solvent, preferably an aqueous solution having a NMP concentration of 45 to 60 wt%.

Specifically, the method is a method of treatment with a spreading non-tension machine in continuous refining and continuous drying. For example, a Softa relaxer, a tenter frame dryer, a spring Surfer, a short-lift dryer, a Luciole dryer, or the like is used. In some cases, the refining and relaxation steps can be omitted.
Additionally, trimming and/or singeing may be performed in order to enhance other characteristics. Further, various other processes for imparting functions such as an antiperspirant, a water repellent, a heat storage agent, an ultraviolet shielding agent, an antistatic agent, an antibacterial agent, a deodorant, an insect repellent, an anti-mosquito agent, a light storage agent, and a retroreflective agent may be performed.

(8) Residual solvent content
About 8.0g of fibrils were collected, dried at 105 ℃ for 120 minutes, cooled in a desiccator, and the fiber was weighed (M1). Next, the fibers were subjected to reflux extraction in methanol for 1.5 hours using a soxhlet extractor, and the amide solvent contained in the fibers was extracted. The fiber after completion of the extraction was taken out, vacuum-dried at 150 ℃ for 60 minutes, cooled in a desiccator, and weighed (M2). The amount of solvent (amide solvent weight) remaining in the fiber was calculated from the following formulae using the obtained M1 and M2.
Residual solvent (%) [ (M1-M2)/M1 ] × 100
(9) Degree of crystallinity
The fibrils were aligned into a fiber bundle having a diameter of about 1mm by using an X-ray diffractometer (RINT TTRIII, Rigaku corporation), and the diffraction pattern was measured by mounting the fiber bundle on a fiber sample stand. The measurement conditions were carried out by scanning a Cu-Kalpha radiation source (50kV, 300mA) at a scanning angle of 10 to 35 DEG at a width of 0.1 DEG for continuous measurement and scanning at 1 DEG/min. The air scattering and the non-interference scattering are approximately corrected by a straight line from the actually measured diffraction pattern to obtain a middle scattering pattern. Next, the amorphous scattering map is subtracted from the intermediate scattering map to obtain a crystalline scattering map. The crystallinity is determined from the area intensity of the crystal scattering pattern (crystal scattering intensity) and the area intensity of the total scattering pattern (total scattering intensity) by the following equation.
Degree of crystallinity (%) [ crystalline scattering intensity/total scattering intensity ] × 100
