PROBLEM TO BE SOLVED: To obtain an antibacterial/deodorant material having excellent heat resistance, readily processible to a product with small possibility of discoloring or denaturating and useful for a medical and sanitary tool, an air cleaner, a building material, daily needs, etc., by dispersing and attaching metal particles such as metallic silver on titanium oxide particles.SOLUTION: This antibacterial/deodorant material is obtained by dispersing and attaching preferably 0.5-5 wt.% of one kind or two kinds of metal particle selected from metallic silver or metallic copper having nanometer order of diameter, preferably &le4 nm average diameter to anatase-typed titanium oxide particles having submicron size, preferably &le0.04 &mum average diameter and having a photocatalytic property. Preferably, the metal particles contain one kind or two kinds of metal selected from platinum and palladium enhancing a catalytic property of titanium oxide. The antibacterial/deodorant material is contained in fibers (e.g. acrylic fibers) used for medical clothing, etc., to give an antibacterial/deodorant fibers or antibacterial/deodorant clothing.COPYRIGHT: (C)1999,JPO【課題】 耐熱性に優れ、変質が少なく品質安定性にも優れた抗菌・脱臭材料を提供する。【解決手段】 平均粒径が0.04μm未満のサブミクロンサイズの光触媒性を有する酸化チタン粒子に、平均粒径が4nm未満のナノメートルオーダーの金属銀および金属銅のうちから選ばれる1種または2種の金属粒子を0.5重量%以上5重量%以下の範囲で分散付着させてなる抗菌・脱臭材料。
