Abstract
Description
本発明は、フィルター材に関し、多孔質炭素繊維の織布及び不織布の吸着機能に加えて、光触媒作用で、消臭作用を増加させ、抗菌作用も付加して、さらにその相互作用で持続的維持を図るため蒸着加工或いは溶射加工してなる消臭材、空気清浄材、抗菌材、水質浄化材等に有益なフィルター材及びその製造方法に関する。 The present invention relates to a filter material, in addition to the adsorption function of woven and non-woven fabrics of porous carbon fibers, increases the deodorizing effect by photocatalytic action, adds antibacterial action, and further maintains the interaction continuously. The present invention relates to a filter material useful for a deodorizing material, an air cleaning material, an antibacterial material, a water purification material, etc. formed by vapor deposition or thermal spraying, and a method for producing the same.
近年、空気環境や水環境に対する関心が非常に高まり、特に人間の生活空間における悪臭や悪細菌類の除去が必要不可欠の時代になってきた。悪臭の除去や水質の浄化方法として、一般に吸着性を利用した良く知られている物として、活性炭、ゼオライト、セピオライト、麦飯石等の多孔質のセラミックがあり、そのなかでも、吸着力の大きい活性炭が悪臭除去や水質浄化の主流になり、また、特殊なものとして、多孔質炭素繊維の織布或いは不織布があり、空気清浄材や水質浄化材として殆どのものが利用されている。 In recent years, interest in the air environment and the water environment has been greatly increased, and it has become an indispensable era of removal of bad odors and bacteria in human living spaces. Well-known materials that use adsorptivity as a method for removing malodor and water purification include activated carbon, zeolite, sepiolite, barley stone, and other porous ceramics. Has become the mainstream for removing bad odors and purifying water, and as special ones, there are woven or non-woven fabrics of porous carbon fibers, and most of them are used as air purifiers and water purifiers.
悪臭除去の空気清浄器や、水質浄化の浄化器、特に、家庭用の蛇口に取り付ける小型浄化器として、塊状の活性炭を小さな網目容器に詰め込み、悪臭や水中の遊離塩素類を瞬時に通過させて、吸着除去するものであるが、殆どの悪臭や水中の遊離塩素類は高濃度でもあり、瞬時に、小型容器に通過させても、大部分、吸着除去できていないのが現状である。すべての悪臭や水質浄化をするには、循環方式か、通過時間の長い大きな容器に詰め込むしかないのが現状である。また、活性炭等の吸着材を使用しているため、吸着が衡量に達すると、取り替える必要があり、また、高濃度の悪臭の場合、短時間で性能が低下しつつ、吸着できない欠点があった。 Odor removal air purifier and water purification purifier, especially as a small purifier attached to a faucet for home use. However, most offensive odors and free chlorine in water are high in concentration, and even if they are passed through a small container instantaneously, most of them cannot be removed by adsorption. Currently, the only way to purify all offensive odors and water quality is to pack them in a circulation system or a large container with a long transit time. In addition, since an adsorbent such as activated carbon is used, it is necessary to replace it when the adsorption reaches a balance. Also, in the case of a high concentration of bad odor, there is a drawback that the performance deteriorates in a short time and cannot be adsorbed. .
一方、悪臭の除去及び抗菌効果の方法として、注目されるようになってきた光触媒機能材料を使った製品が多く市場にみられるようになった。光触媒機能材料の先行技術が特許や出願或いは市場に販売されている。その中で代表的な下記の３件を挙げる。 On the other hand, as a method of removing malodor and antibacterial effect, many products using photocatalytic functional materials that have been attracting attention have come to be seen in the market. Prior art of photocatalytic functional materials are sold in patents, applications or markets. The following are three typical examples.
本発明において解決しようとする問題点は、高濃度の悪臭を除去する消臭材及び水中の遊離塩素類を除去する浄化材として、小型の容器或いは有形成形品たとえば、平板状型状に、通過させるだけで除去できる素材が必要になってきた点であり、また、活性炭バインダー付着フィルターや光触媒バインダー付着フィルターや活性炭バインダー付着複合フィルターに代わる素材が必要になってきた。また、多孔質炭素繊維フィルターでは、抗菌性がない為、悪臭の除去と同時に、悪細菌も殺菌させ、さらに光触媒の欠点である離れたところでも抗菌効果及び消臭作用が促進されるような素材が必要になってきた。 The problem to be solved in the present invention is that as a deodorizing material for removing high-concentration malodor and a purifying material for removing free chlorine in water, a small container or a shaped product, for example, a plate-like mold is passed. In addition, a material that can be removed simply by making it necessary has become necessary, and a material that can replace the activated carbon binder-attached filter, the photocatalyst binder-attached filter, and the activated carbon binder-attached composite filter has become necessary. In addition, porous carbon fiber filter has no antibacterial properties, so it can disinfect odors at the same time as it removes malodors, and further promotes antibacterial and deodorizing effects even at remote locations, which is a disadvantage of photocatalysts. Has become necessary.
上記問題点に鑑みて、吸着性のある多孔質炭素繊維の織布及び不織布或いはフェルトの両面或いは片面に、光触媒機能材料を蒸着加工或いは溶射加工したフィルター材が、悪臭物質及び悪細菌を吸着すると同時に、吸着した悪臭物質及び悪細菌を光触媒機能作用で、消臭分解及び抗菌作用が維持される機能を発揮し得るフィルター材に到達した。 In view of the above problems, when a filter material obtained by vapor-depositing or spraying a photocatalytic functional material on both sides or one side of an adsorbent porous carbon fiber woven fabric and non-woven fabric or felt adsorbs malodorous substances and bacteria. At the same time, the adsorbed malodorous substance and malodorous bacteria reached the filter material that can exhibit the function of maintaining the deodorizing decomposition and antibacterial activity by the photocatalytic function.
本発明において、多孔質の炭素繊維の織布及び不織布として、織布及び不織布を直接炭化賦活した活性炭素織布及び活性炭素不織布、繊維糸を直接炭化した活性炭素繊維を紡織及び不織布化或いはフェルト化した活性炭素織布及び活性炭素不織布或いは活性炭素フェルトをいずれも使用することができる。市販品として、例えば、商品名カイノール 活性炭素繊維クロス及び活性炭繊維不織布 日本カイノール社製を使用することができる。 In the present invention, as the porous carbon fiber woven fabric and nonwoven fabric, the activated carbon woven fabric and activated carbon nonwoven fabric obtained by directly carbonizing the woven fabric and nonwoven fabric, and the activated carbon fiber obtained by directly carbonizing the fiber yarn are spun and formed into a nonwoven fabric or felted.
