Description
【０００１】
【発明の属する技術分野】
本発明は、アラミド繊維布帛に耐久性のある吸水・吸放湿、制電性の機能を付加する加工を施し、すなわち、アラミド繊維布帛を改質処理し、このように改質処理したアラミド繊維布帛を用いた難燃性下着又は該アラミド繊維布帛をインナー材として用いた衣服に関する。本発明によれば、着心地に優れた難燃・耐熱あるいは高強力作業衣・肌着等を提供することが可能となる。
【０００２】
【従来の技術】
アラミド繊維布帛を衣料用素材として使用する場合は、アラミド繊維の難燃・耐熱あるいは高強力を利用した防護服や防火・難燃作業服としての用途が主流であったが、アラミド繊維布帛は吸水性や放湿性がほとんどなく、着心地面（風合い・快適性）で問題があり、特に発汗やムレや臭いの問題が解消できなかった。
【０００３】
これらを改良するために後加工を施すと、風合いが硬くなるなどしていわゆる衣料用布帛としての着心地・快適性がそこなわれるなどの問題が起こり、風合いを維持しながら耐久性のある機能をアラミド繊維布帛に付加することは困難であった。

【発明が解決しようとする課題】
本発明の目的は、アラミド繊維本来の機能性・特性（難燃性、耐熱性、高強力な素材）を維持しながら耐久性のある吸水・吸放湿・制電性の機能を付加して衣料用途としての快適性・着心地性に優れたアラミド繊維布帛とし、このアラミド繊維布帛をインナー材として用いた衣服を提供することにある。また、そのような衣服として難燃性下着、作業服又は防火服を提供することにある。
【０００６】
ここで、難燃性下着（難燃性アンダーウエア）は、例えば、難燃作業服の下着、防火服の下着などである。また、アラミド繊維布帛をインナー材として用いた衣服は、例えば、作業服、防火服などである。
【０００７】
【課題を解決するための手段】
本発明は、下記式（１）
【０００８】
【化３】
【０００９】
【化４】
【００１０】
このように改質処理したアラミド繊維布帛を用いるために上記目的の達成が可能となる。
【００１１】
ところで、従来のメタ系９０〜９９％、パラ系１０〜１％の芳香族ポリアミドからなるアラミド繊維布帛（従来品）とそれに本発明の処理を施したアラミド繊維布帛（本発明品）を着用快適性の観点から比較すると下記のようになり、従来品が着用快適性に欠けていることがわかる。

【００２５】
メタ系９０〜９９％、パラ系１０〜１％の芳香族ポリアミドからなるアラミド繊維布帛に繊維処理液を接触させる方法としては特に限定されないが、浸漬処理法やパディング法等が挙げられる。
【００２６】
例えば、パディング法では、アラミド繊維布帛に繊維処理液を接触させた後、必要に応じて繊維布帛を絞り、繊維処理液の付着量を調整する。さらに、必要に応じて５０〜１３０℃程度で加熱乾燥（乾熱処理）する。なお、乾熱処理だけでは重合反応は進行しにくい。
【００２７】
以上の処理を行なった後、重合を行なう。（Ａ）〜（Ｃ）の重合は、繊維処理液が付着したアラミド繊維布帛に対して湿熱処理、電子線照射処理、紫外線照射処理、マイクロ波照射処理等の処理を施すことにより行なうことができる。湿熱処理を採用する場合は、例えば水蒸気を満たした９０〜１４０℃程度の雰囲気中にて１〜９０分間程度処理すれば良い。電子線照射処理、紫外線照射処理、マイクロ波照射処理を採用する場合には、重合反応の際に周囲の雰囲気を窒素等により置換すると、発生したラジカルの消失を防ぎ、重合成分の有効利用率の向上を図ることができるので好ましい。重合反応終了後、アラミド繊維布帛に付着している未反応化合物を除去するため、洗浄を行なうことが好ましい。
【００２８】
つぎに、乾燥を行なった後、例えばピリジン系の抗菌剤をパディング法で付与することも出来る。パディング法では、アラミド繊維布帛に、繊維処理液を接触した後、必要に応じて繊維布帛を絞り、繊維処理液の付着量を調整する。さらに５０〜１３０℃で加熱乾燥を行ない、さらに最終仕上熱処理を１４０〜１９０℃で固定化を行なう。
【００２９】
このピリジン系の抗菌剤は染色時に染料と同時に浸漬処理で固定化することも可能である。この場合はピリジン系の薬剤を０．５〜８％ｏｗｆ濃度で入れることにより、耐久性のある固着を行なうことができる。

[0018]
[Chemical 7]
In the present invention, these (A), (B), and (C) are attached to an aramid fiber fabric made of aromatic polyamide of 90 to 99% meta and 10 to 1% para. For this adhesion, these (A), (B), and (C) may be dissolved or suspended in a solvent to form a fiber treatment liquid, and the fiber treatment liquid may be brought into contact with the aramid fiber fabric. As the concentration in the fiber treatment liquid, (A) is preferably about 1 to 20% by weight, and the blending ratio of (B) and (C) is preferably 1: 0.05 to 1: 0.01-1.
[0020]
The polymerization of (A), (B) and (C) is performed by graft polymerization.
[0021]
Furthermore, an antibacterial agent may be attached in order to impart antibacterial properties to an aramid fiber fabric composed of 90% to 99% meta-based and 10% to 1% para-based aromatic polyamide.
[0022]
Antibacterial agents include inorganic / zeolite / silver, metal copper and other metal salts, organic / phenolic phenols such as alkylenebisphenol sodium salt, benzalkonium chloride, cetyltrimethylammonium chloride, quaternary ammonium salts such as polyyneone, undecylen Esters such as acid monoglycerite, pyranides such as chlorhexidine gluconate, pyridines of zinc bis (2-pyridylthio-1-oxide), terpenes of lemon eucalyptus oil in natural products, sugars such as chitosan, hinokitiol, etc. There are tropolones. Of these, pyridine zinc bis (2-pyridylthio-1-oxide) is preferable because of its good durability. The concentration used is preferably 0.5 to 8% owf concentration in the bath exhaustion method and 1 to 8% mass concentration in the padding method.
[0023]
Next, the modification treatment of the aramid fiber fabric of the present invention will be specifically described.
Modification treatment of the present invention The solvent used in the fiber treatment liquid is not particularly limited, and water and organic solvents (alcohols, dimethylformamides, acetones, etc.) can be used. A solvent may be used individually by 1 type and can also use 2 or more types together. In particular, an aqueous solvent is preferably used as the solvent. Examples of the aliphatic lower alcohol having 1 to 3 carbon atoms include methyl alcohol, ethyl alcohol, isopropyl alcohol and the like, and these may be used alone or in combination of two or more.
[0024]
In addition to (A) to (C) and the solvent, various additives may be added to the fiber treatment liquid. For example, reactive resins such as melamine resins, glyoxal resins, and epoxy resins may be added to crosslink these during the polymerization of (A) to (C). Polymerization initiators such as potassium peroxide, ammonium persulfate, hydrogen peroxide, benzoyl peroxide, azobisisobutyronitrile, and tertiary butyl peroxide may be added. In order to develop a higher moisturizing effect, natural polymers such as sericin, silk fibroin, collagen, and protein may be added. In the fiber treatment liquid, the amount of (A) to (C) can be prepared by adding various additives as necessary.
[0025]
Although it does not specifically limit as a method of making a fiber treatment liquid contact the aramid fiber fabric which consists of a meta type | system | group 90-99% and a para type | system | group aromatic polyamide, Although a dipping treatment method, a padding method, etc. are mentioned.
[0026]
For example, in the padding method, after bringing the fiber treatment liquid into contact with the aramid fiber cloth, the fiber cloth is squeezed as necessary to adjust the amount of the fiber treatment liquid attached. Furthermore, it heat-drys at about 50-130 degreeC (dry heat processing) as needed. It should be noted that the polymerization reaction is unlikely to proceed only by dry heat treatment.
[0027]
Polymerization is performed after the above treatment. The polymerization of (A) to (C) can be performed by subjecting the aramid fiber fabric to which the fiber treatment liquid is adhered to a treatment such as a wet heat treatment, an electron beam irradiation treatment, an ultraviolet ray irradiation treatment, and a microwave irradiation treatment. . When the wet heat treatment is employed, for example, the treatment may be performed for about 1 to 90 minutes in an atmosphere of about 90 to 140 ° C. filled with water vapor. When using electron beam irradiation treatment, ultraviolet irradiation treatment, or microwave irradiation treatment, replacing the surrounding atmosphere with nitrogen or the like during the polymerization reaction prevents the disappearance of the generated radicals and increases the effective utilization rate of the polymerization components. Since improvement can be aimed at, it is preferable. After completion of the polymerization reaction, washing is preferably performed to remove unreacted compounds adhering to the aramid fiber fabric.
[0028]
Next, after drying, for example, a pyridine antibacterial agent can be applied by a padding method. In the padding method, after the fiber treatment liquid is brought into contact with the aramid fiber cloth, the fiber cloth is squeezed as necessary to adjust the adhesion amount of the fiber treatment liquid. Furthermore, heat drying is performed at 50 to 130 ° C., and the final finishing heat treatment is fixed at 140 to 190 ° C.
[0029]
This pyridine-based antibacterial agent can be fixed by dipping at the same time as the dye at the time of dyeing. In this case, durable fixation can be performed by adding a pyridine-based drug at a concentration of 0.5 to 8% owf.
