〔産業上の利用分野〕
本発明は、消臭機能を有する繊維の製造方法に関するも
のである。更に詳しくは、タンニン酸と遷移金属との反
応生成物が消臭成分として繊維中に固着されてなる消臭
性繊維の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for producing fibers having a deodorizing function. More specifically, the present invention relates to a method for producing deodorant fibers in which a reaction product of tannic acid and a transition metal is fixed as a deodorizing component in the fibers.
アンモニア、硫化水素、メルカプタン類などの悪臭物質
を除去する物質として、ツバキ科植物抽出物や、二価鉄
化合物/L−アスコルビン酸配合物など多くの消臭剤が
開発されている。又、繊維製品自体に消臭機能を付与す
る試みとして、これらの消臭剤を利用した繊維あるいは
、繊維製品が多(開発されようとしている。Many deodorants have been developed as substances that remove malodorous substances such as ammonia, hydrogen sulfide, and mercaptans, such as extracts from plants of the Camellia family and mixtures of divalent iron compounds and L-ascorbic acid. Furthermore, in an attempt to impart a deodorizing function to textile products themselves, many fibers or textile products using these deodorants are being developed.
繊維に消臭機能を付与しようとする場合、その方法には
、大きく分けて二つが考えられる。When attempting to impart a deodorizing function to fibers, there are two main ways to do so.
一つは、合成繊維などを紡糸して繊維を作る場合に、紡
糸原液中に消臭剤を混入しておく方法であり、二つめは
、繊維の状態となったものに後処理の形で消臭剤を付与
するものである。One is to mix a deodorant into the spinning solution when spinning synthetic fibers to make fibers, and the second is to add a deodorant to the spinning solution after it has become a fiber. It provides a deodorant.
紡糸原液中に消臭剤を混入しておく方法においては、消
臭剤自体に紡糸条件に匹敵する耐熱性や耐薬品性が要求
される。更に、混入された消臭剤は、繊維を形成する高
分子の中におおわれている為に、本来の消臭能力を十分
に発揮することができなくなり、より多くの消臭剤が必
要となるなどの欠点を有する。In the method of mixing a deodorant into the spinning dope, the deodorant itself is required to have heat resistance and chemical resistance comparable to the spinning conditions. Furthermore, since the mixed deodorizer is covered in the polymer that forms the fibers, it is no longer able to fully demonstrate its original deodorizing ability, and more deodorant is required. It has drawbacks such as:
更に又、天然繊維など紡糸によらない繊維にこの方法を
適用することもできず、加えて、経済的見地からは、繊
維状態となったものに後処理の形で消臭加工する方が好
ましい。Furthermore, this method cannot be applied to fibers that are not spun, such as natural fibers, and in addition, from an economic standpoint, it is preferable to deodorize the fibers in the form of post-processing. .
一方、後処理による繊維の消臭加工においては、はとん
どの消臭剤が繊維自体への親和性を持たない為に、単に
表面に付与するだけであったり、あるいは、樹脂などに
よって固定するという方法が、はとんどである。On the other hand, when deodorizing fibers through post-processing, most deodorants do not have an affinity for the fibers themselves, so they are simply applied to the surface of the fibers, or are fixed with resin, etc. This is the most common method.
前者の場合、洗濯はもちろん、使用時の物理的な接触や
振動によっても、消臭剤は簡単に脱落してしまう。In the former case, the deodorant easily comes off not only during washing but also due to physical contact and vibration during use.
又、後者の場合には、耐久性は向上しているが、樹脂な
どで消臭剤が被覆されている為、紡糸の場合と同様、そ
の消臭剤本来の消臭能力を十分に発揮することができな
い。更に固定に使用する樹脂などによっては、繊維自体
の持つ機能、すなわち親木性や、かさ高検、更には、風
合をもそこねる場合がある。In the latter case, although the durability is improved, since the deodorant is coated with resin etc., the original deodorizing ability of the deodorant cannot be fully demonstrated, as in the case of spinning. I can't. Furthermore, depending on the resin used for fixing, the functions of the fibers themselves, such as wood-loving properties, bulkiness, and even texture, may be impaired.
一方、後処理において繊維を消臭加工する方法の中に、

れている。On the other hand, among the methods of deodorizing fibers in post-processing,
Development is also underway to use deodorants that have an affinity for the fibers themselves.

しないので、消臭剤の能力が十分に発揮できる点におい
て、優れた方法である。This method depends on the affinity between the fiber and the deodorant, so it can only be applied to certain combinations, but it can be processed in post-processing, and it does not use resin for fixation. This is an excellent method in that it allows the deodorant to fully demonstrate its capabilities.

繊維にも、応用される方法は、未だ開発されていない。As an example, a method is actually used in which metal phthalocyanine is supported on porous rayon.
Other methods have not yet been developed, and methods that can be applied not only to synthetic fibers and recycled fibers but also to natural fibers such as cotton, linen, wool, and silk have not yet been developed.

法を開発した。Therefore, as a result of intensive study, the present inventors found that cotton, linen, wool,
Natural fibers such as silk, as well as some recycled fibers and synthetic fibers, can be processed with a deodorizing agent that has an affinity for them. We have developed a method for producing fibers that have a strong deodorizing function without requiring fixation, thereby causing a deterioration in the performance of the deodorant, and without impairing the original functions of the fibers.

がなされているにすぎない。Conventionally, attempts have been made to utilize tannic acid and tannic acid derivatives to deodorize malodorous substances. (Japanese Patent Application Laid-open No. 54-8725, etc.) It is thought that this effect is responsible for the fact that it can also be used as an additive for cigarette filters. (Japanese Patent Publication No. 54-18358, Japanese Patent Publication No. 57-118
785, etc.) However, these products use tannic acid or tannic acid derivatives as they are in the form of powder or granules, and are simply used in the same way as deodorants such as activated carbon.
我々はタンニン酸と遷移金属との反応生成物が、消臭成

繊維に担持させる検討を行った。We have confirmed that the reaction product of tannic acid and transition metals is very effective as a deodorizing component, and have investigated supporting this deodorizing component on fibers.
しかし、タンニン酸と遷移金属との反応生成物のおおく

ある。However, most of the reaction products of tannic acid and transition metals are water-insoluble and do not have good affinity even when applied to fibers as they are, making it practically impossible to treat them.

担持繊維の製造方法を開発したものである。Therefore, we focused on the fact that tannic acid has a strong affinity for specific fibers, and developed a method in which the relevant fibers are loaded with transition metals in advance, and then the transition metal-loaded fibers are treated with tannic acid. As a result, a method for producing strongly fixed deodorant-carrying fibers without using any fixing agent such as resin was developed.
