PROBLEM TO BE SOLVED: To provide a nonwoven fabric for bedding that has an ability to decompose and remove a wide variety of kinds of odor causative substances effectively and persistently.SOLUTION: A nonwoven fabric for bedding is composed of a substance decomposing/removing short fiber and a short fiber other than a substance decomposing/removing short fiber. The substance decomposing/removing short fiber is composed of a short fiber having an air catalyst on a surface of the fiber and a crosslinked acrylate-based moisture-absorbing/releasing short fiber. The air catalyst is composed of a metal composition comprising iron, aluminum, potassium and titanium and the metal composition contains 100-500 ppm of aluminum, 0.5-50 ppm of potassium, and 0.1-50 ppm of titanium based on 100 ppm of iron. The substance decomposing/removing short fiber contains the metal composition in an amount of 0.01 mass% or more and the crosslinked acrylate-based moisture-absorbing/releasing short fiber in an amount of 50 mass% or more.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】幅広い種類の臭気原因物質を効果的かつ持続的に分解除去する能力を有する寝具用不織布を提供する。【解決手段】鉄、アルミニウム、カリウム、及びチタンを含む金属組成物からなり、かつ金属組成物中の金属含有割合が鉄100ppmに対してアルミニウム100~500ppm、カリウム0.5~50ppm、チタン0.1~50ppmである空気触媒を繊維表面に付着した短繊維、及び架橋アクリレート系吸放湿性短繊維からなる物質分解除去短繊維と、物質分解除去短繊維以外の短繊維とからなる寝具用不織布であって、物質分解除去短繊維中の金属組成物の含有量が0.01質量%以上であり、架橋アクリレート系吸放湿性短繊維の含有量が50質量%以上である。【選択図】なし
