The present invention provides a nonwoven fabric for bedding, padding for bedding, woven fabric for bedding, or knitted fabric for bedding that has an ability to effectively and sustainably decompose and remove a wide variety of substances which are cause of bad smell.The nonwoven fabric for bedding, padding for bedding, woven fabric for bedding, or knitted fabric for bedding according to the present invention uses substance decomposing and removing fibers which comprises fibers having an air catalyst adhered thereon, and cross-linked acrylate moisture absorbing/releasing fibers, wherein the air catalyst comprises a metal composition containing iron, aluminum, potassium, and titanium, and wherein a proportional content of metals in the metal composition, relative to 100 ppm of iron, is 100-500 ppm of aluminum, 0.5-50 ppm of potassium, and 0.1-50 ppm of titanium. Content of the metal composition in the substance decomposing and removing fibers of the nonwoven fabric for bedding, padding for bedding, woven fabric for bedding, or knitted fabric for bedding is 0.01% by mass or more. Content of the cross-linked acrylate moisture absorbing/releasing fibers is 50% by mass or more.本發明提供一種寢具用不織布、棉胎、梭織物或針織物，其具有有效且持續地分解除去種類廣泛的臭氣原因物質的能力。本發明之寢具用不織布、棉胎、梭織物或針織物係使用物質分解除去纖維，該物質分解除去纖維包含空氣觸媒附著於纖維表面而成的纖維、及交聯丙烯酸酯系吸放濕性纖維，該空氣觸媒包含含有鐵、鋁、鉀及鈦的金屬組成物，且金屬組成物中的金屬含有比例係相對於鐵100ppm，鋁為100~500ppm，鉀為0.5~50ppm，鈦為0.1~50ppm。寢具用不織布、棉胎、梭織物或針織物的物質分解除去纖維中之金屬組成物的含量為0.01質量%以上，交聯丙烯酸酯系吸放濕性纖維的含量為50質量%以上。
