PHOTO-REACTIVE HARMFUL MATTER-REMOVING MATERIAL AND PRODUCTION THEREOF

摘要

PURPOSE: To obtain a photo-reactive harmful matter-removing material utilizing titanium oxide being a photocatalyst, having the decomposition capacity of a harmful substance such as a malodor or antibacterial properties, excellent in processability or handleability and capable of being produced in low cost. CONSTITUTION: A photo-reactive harmful matter-removing material has constitution such that titanium oxide precipitated from a titania sol is supported on a nonwoven fabric containing a thermoplastic resin fiber or a glass fiber and is produced by impregnating the nonwoven fabric with the titania sol and treating the impregnated nonwoven fabric with an aq. soln. of an alkali agent containing alkali metal hydroxide or carbonate and drying the treated nonwoven fabric to support titanium oxide on the surface of the nonwoven fabric as fine floc.
