等に抄き込んだ吸着性を有する紙等が提案されている。Conventional filter paper materials have been proposed, such as paper made by mixing powder or granular activated carbon with cotton linter or other fibrous materials, or paper with adsorption properties made by mixing nonwoven fabric.
しかし、これら粉末、粒状活性炭は粒子の大きさの関係
で紙等を横取する繊維で充分保持することができず、活
性炭が脱落する欠点がある。However, due to the size of the particles, these powdered and granular activated carbons cannot be sufficiently retained by fibers that pick up paper and the like, resulting in the activated carbon falling off.
脱落防止のため粉末、粒状活性炭を繊維材料とともに粘

分子物質からなる合皮パルプ等が挙げられる。Other fiber materials in the present invention include natural fibers such as natural pulp and cotton, chemical fibers such as rayon, polyvinyl alcohol, polyester, and polyamide, and synthetic leather pulp made of synthetic polymeric substances.
繊維状活性炭及び他の繊維材料は濾紙の目的に適した繊
維直径、繊維長のものを使用して混合抄紙する。The fibrous activated carbon and other fibrous materials are mixed to form a paper using fiber diameters and fiber lengths suitable for the purpose of the filter paper.
混合比率は吸着性、濾過性、通気性、濾紙強度等の関係
から適宜法められるが、繊維状活性炭は少なくとも10
重量%以上含有させるのがよい。The mixing ratio is determined as appropriate based on adsorption properties, filtration properties, air permeability, filter paper strength, etc., but the fibrous activated carbon should be at least 10%
The content is preferably at least % by weight.
