本発明は、脱臭材に関し、さらに詳しくは、活性炭素繊
維と植物繊維からなる脱臭材に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a deodorizing material, and more particularly to a deodorizing material made of activated carbon fiber and vegetable fiber.
従来より、脱臭材として、粒状、粉状にした活性炭を容
器に充填したもの１粒状活性炭を布やペーパーなどに粘
着加工し、これを多層構造としたものがある。BACKGROUND ART Conventionally, deodorizing materials include containers filled with granular or powdered activated carbon, and granular activated carbon adhesively processed into cloth, paper, etc. to form a multilayer structure.
しかし、粒状活性炭を容器に充填したものは。However, the container is filled with granular activated carbon.
脱臭性能に劣り、また、粒状活性炭を布やペーパー状に
付着したものは、粒状物が剥離しやすく、かつ脱臭性能
が劣る欠点があった。The deodorizing performance is poor, and when granular activated carbon is attached to cloth or paper, the granular materials tend to peel off easily and the deodorizing performance is poor.
そのため、活性炭素繊維が軽量で優れた吸着能をもち、
かつ、織布、不織布に加工しやすい点を利用して、活性
炭素繊維をフェルトまたはマット状に形成した脱臭材が
開発された（特開昭６２−２５３０７２号公報）。Therefore, activated carbon fiber is lightweight and has excellent adsorption ability.
Also, taking advantage of the fact that it is easy to process into woven or non-woven fabrics, a deodorizing material in which activated carbon fibers are formed into felt or mat shapes has been developed (Japanese Patent Application Laid-open No. 253072/1983).
また、有機バインダーの存在下に、粉末状または繊維状
の活性炭とアスベスト繊維とを混抄して平板繊維紙を調
整し、これを積層結合した吸着ユニット（特開昭５７−
５６０１９号公報）が、さらに、活性炭素繊維とオルト
リン酸とともに抄紙してシート状にしたもの（特開昭６
０−９９９９号公報）等が開示されている。In addition, in the presence of an organic binder, powdered or fibrous activated carbon and asbestos fibers are mixed to prepare flat fiber paper, and this is laminated into an adsorption unit (Japanese Unexamined Patent Application Publication No. 57-119).
No. 56019) was further made into a sheet with activated carbon fibers and orthophosphoric acid (Japanese Patent Laid-Open No. 6
No. 0-9999), etc. are disclosed.
しかし、活性炭素繊維をフェルトまたはマット状に形成
したものは、厚く取扱に難゛がある。However, activated carbon fibers formed into felt or mat shapes are thick and difficult to handle.
また、特開昭５７−５６０１９号公報に代表される従来
の活性炭素繊維を用いるものは、結合材を使用するため
、炭素繊維の性能が結合材により阻害され、特に、アン
モニア等の脱臭機能が劣り、またすべての臭気成分の脱
臭効果を得ることができない欠点がある。In addition, conventional activated carbon fibers as exemplified by JP-A No. 57-56019 use a binder, so the performance of the carbon fiber is inhibited by the binder, and in particular, the deodorizing function of ammonia etc. It also has the disadvantage that it cannot deodorize all odor components.
さらに、特開昭６０−９９９９号公報に示すシート状に
するものは、成形品が脱臭効果を得るためには、積層を
重ねる必要があり、必然的にシーＩ・状物質が厚くなり
、薄くて優れた臭気性能を有する脱臭材を得るのは困難
であるという問題点があった。Furthermore, in the sheet-shaped product shown in JP-A-60-9999, in order for the molded product to obtain a deodorizing effect, it is necessary to stack multiple layers, which inevitably results in thicker and thinner sheets. However, there has been a problem in that it is difficult to obtain a deodorizing material with excellent odor performance.
本発明者らは、これら従来の脱臭材の問題点を解決し、
薄くても、すべての臭気成分に対して優れた脱臭効果を
有する脱臭材を提供することを目的として鋭意研究した

優れた脱臭効果を有するとの知見を得て本発明を完成し
た。The present inventors solved the problems of these conventional deodorizing materials,
As a result of intensive research aimed at providing a deodorizing material that is thin but has excellent deodorizing effects against all odor components, we found that a deodorizing material made of vegetable fiber and activated carbon fiber does not require a binder. The present invention was completed based on the knowledge that the performance of activated carbon fibers is not inhibited by binders and that even if the fibers are thin, they have an excellent deodorizing effect on all kinds of odors.
