More specifically, the present invention relates to a fiber in which a part of the ion-exchange fiber is replaced with a metal having an antibacterial effect and which simultaneously satisfies the two required performances of the deodorant effect and the antibacterial effect.

ものを設計し製造することが極めて困難であった。However, most of the zeolites carrying the metal ions are in the form of granules, so that the active surface area is small and the effect is unsatisfactory. Further, they are processed into sheets and used. In this case, the manufacturing process is complicated and there is a drawback that a good quality product cannot be obtained.
On the other hand, the one in which the metal ion is held on alumina or activated carbon has problems in deodorizing performance and sustainability of sterilizing power because it is physical adsorption. The silver or copper ion exchange fiber was not satisfactory for both deodorizing and antibacterial properties at the same time, and was also unsatisfactory. Therefore, it has been extremely difficult to design and manufacture a conventional product that sufficiently satisfies both the deodorizing effect and the antibacterial effect.

Ｋ）を用いて同様の試験を行なった（比較例２）。Deodorization rate (%) = (1-concentration at the time of measurement / initial concentration) × 100 Next, a commercially available adsorbent for ammonia (CA104 manufactured by Shigematsu)
The same test was performed using K) (Comparative Example 2).
【００４１】それぞれの結果を表２にまとめて示した。The respective results are summarized in Table 2.

【発明の効果】本発明の消臭抗菌繊維は、社会的要求の
高い消臭と抗菌の両方の効果を同時に満足するものであ
り、さらに効果の持続性、使い易さ、製造の容易さなど
従来のものに比べて優れている。EFFECT OF THE INVENTION The deodorant antibacterial fiber of the present invention satisfies both the deodorant and antibacterial effects which are highly required by society at the same time, and further, the sustainability of the effect, the ease of use, the ease of production, etc. It is superior to the conventional one.
【００４４】このため、各種フィルター素材への適用は
勿論、消臭作用と抗菌作用の両方を必要とする用途に有
効に利用できる。Therefore, it can be effectively applied not only to various filter materials but also to applications requiring both deodorizing action and antibacterial action.
