Description
本発明は、機能性繊維布帛及びその製造方法に関する。 The present invention relates to a functional fiber fabric and a method for producing the same.
ポリエステルをはじめとする合成繊維は、洗濯を行ってもしわになりにくく、また、収縮等も起こりにくい、乾燥が速い、強度が強い等のイージーケア性を有している。その一方で、静電気が発生しやすく、また、まとわりつきやすい、水（汗）を吸いにくい、脂汚れが付きやすいといった欠点を有している。 Synthetic fibers such as polyester have easy care properties such that they do not easily wrinkle even after washing, are less susceptible to shrinkage, fast drying, and high strength. On the other hand, it has the disadvantages that static electricity is likely to occur, it is easy to cling, it is difficult to absorb water (sweat), and oily stains are easily attached.
そこで、親水性を有するジビニルモノマーやアクリル酸等の単量体とアジリン基を含む単量体とを繊維布帛上で重合させることで、ポリエステル等の合成繊維に、制電性、吸水性、汚れ除去性を付与するという技術が知られている。 Therefore, by polymerizing a monomer such as a divinyl monomer or acrylic acid having hydrophilicity and a monomer containing an azirine group on a fiber fabric, the synthetic fiber such as polyester can be antistatic, water-absorbing, and soiling. A technique for imparting removability is known.
また、絹は、静かな深い光沢、柔らかい風合い、優美なドレープ性等の性質を有し、繊維の中でも頂点素材として高く評価されている。そのため、絹以外の繊維を用いて、絹の特性を有する繊維布帛を製造する技術が検討されており、上記ポリエステル等の合成繊維を用いて絹の特性を有する繊維布帛を製造する技術が提案されている。 Silk has properties such as quiet deep luster, soft texture, and graceful drape, and is highly regarded as an apex material among fibers. Therefore, a technique for producing a fiber cloth having silk characteristics using fibers other than silk has been studied, and a technique for producing a fiber cloth having silk characteristics using synthetic fibers such as the above-described polyester has been proposed. ing.

In addition, it is disclosed that a fiber fabric having silk properties in addition to antistatic properties, water absorption, and dirt removal properties can be obtained by polymerizing these compounds on the fiber fabric using this treatment liquid.
しかしながら、特許文献１に開示された繊維布帛の製造方法は、アクリル酸等の単量体とアジリジン基を含む単量体とを含む処理液を用いなければならず、加工安定性に優れていないという問題がある。 However, the method for producing a fiber fabric disclosed in Patent Document 1 must use a treatment liquid containing a monomer such as acrylic acid and a monomer containing an aziridine group, and is not excellent in processing stability. There is a problem.

The present inventors have found a method for producing a fiber fabric having properties and functionality having excellent durability. That is, in the conventional method for producing a fiber fabric, a monomer such as acrylic acid and a monomer containing an aziridine group are used. By using a carbodiimide-based crosslinking agent in place of these monomers, durability can be improved. It has been found that a fiber fabric having excellent properties such as antistatic properties and water absorption properties and properties close to silk can be obtained.

And a liquid contact step for applying the treatment liquid by bringing the treatment liquid into contact with the fiber fabric, and a polymerization step for polymerizing the hydrophilic compound and the carbodiimide-based crosslinking agent on the fiber fabric. In the present embodiment, the hydrophilic compound and the carbodiimide-based crosslinking agent are simultaneously polymerized on the fiber fabric.
繊維布帛に処理液を接触させる方法としては、特に限定されるものではないが、浸漬処理法やパディング法等が挙げられる。例えば、パディング法では、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。乾熱処理だけでは重合反応は進行しにくいので、さらに必要に応じて、５０〜１３０℃程度で加熱乾燥（乾熱処理）してもよい。 A method for bringing the treatment liquid into contact with the fiber fabric is not particularly limited, and examples thereof include an immersion treatment method and a padding method. For example, in the padding method, after the fiber treatment liquid is brought into contact with the fiber cloth, the fiber cloth is squeezed as necessary to adjust the amount of the fiber treatment liquid attached. Since the polymerization reaction does not easily proceed only by dry heat treatment, it may be further heat-dried (dry heat treatment) at about 50 to 130 ° C. if necessary.
親水性化合物とカルボジイミド系架橋剤との重合方法は、前記の熱処理に限定されるものではなく、乾熱処理を行った後、又は、乾熱処理を行わずに、例えば、処理液が付着した繊維布帛に対して、湿熱処理（水蒸気熱処理）、電子線照射処理、紫外線照射処理、又は、マイクロ波照射処理等の処理を施すことによって行うことができる。 The polymerization method of the hydrophilic compound and the carbodiimide-based crosslinking agent is not limited to the above-mentioned heat treatment. For example, the fiber fabric to which the treatment liquid is attached after performing the dry heat treatment or without performing the dry heat treatment. On the other hand, it can be performed by performing a wet heat treatment (water vapor heat treatment), an electron beam irradiation treatment, an ultraviolet irradiation treatment, a microwave irradiation treatment or the like.
このとき、湿熱処理を採用する場合には、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。また、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、使用する繊維布帛及び処理液に合わせて、照射強度等の条件を適宜調整する。さらに、この場合、接液工程の前にあらかじめ電子線、紫外線、又はマイクロ波を照射しておいても良いし、接液工程の後に照射を行っても良い。また、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ことが好ましい。これにより、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。 At this time, 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. Moreover, when employ | adopting an electron beam irradiation process, an ultraviolet irradiation process, and a microwave irradiation process, conditions, such as irradiation intensity | strength, are suitably adjusted according to the fiber fabric and process liquid to be used. Further, in this case, irradiation with an electron beam, ultraviolet light, or microwave may be performed in advance before the liquid contact process, or irradiation may be performed after the liquid contact process. Further, when an electron beam irradiation treatment, an ultraviolet irradiation treatment, or a microwave irradiation treatment is employed, it is preferable to replace the surrounding atmosphere with nitrogen or the like during the polymerization reaction. Thereby, the loss | disappearance of the produced | generated radical can be prevented and the improvement of the effective utilization factor of a polymerization component can be aimed at.
なお、本実施の形態では、この重合工程において、繊維の表面のみならず、繊維の内部（線異種にもよるが、主に繊維表面近傍）でも重合反応が進行する。また、重合反応終了後、繊維布帛に付着している未反応化合物を除去するために、所定の洗浄を行うことが好ましい。さらに、接液工程の前、同時あるいは重合工程の後に、繊維布帛に対して、抗菌剤、ＳＲ剤、防炎剤、帯電防止剤等を付与することも可能である。 In the present embodiment, in this polymerization step, the polymerization reaction proceeds not only on the surface of the fiber but also inside the fiber (mainly near the fiber surface, although depending on the type of the line). In addition, after the polymerization reaction is completed, it is preferable to perform predetermined washing in order to remove unreacted compounds adhering to the fiber fabric. Furthermore, an antibacterial agent, an SR agent, a flameproofing agent, an antistatic agent, etc. can be applied to the fiber fabric before the liquid contact step, simultaneously or after the polymerization step.

In this case, the water-solubilized peptide of silk and / or silk fibroin is polymerized together with the hydrophilic compound and the carbodiimide-based crosslinking agent in the polymerization step.
