Abstract
The preparations of deodorizing fibers using TiO2 have been investigated. The fibers were coated with TiO2 for the purpose of deodorizing by dipping fibers into the TiO2 sol solutions and calcined at 450℃, 500℃ and 750℃ for 1 h after coating. The surface structure of the coated fibers was studied with XRD on the different preparation conditions of calcination temperatures. The deodorizing function of the prepared fibers was studied by the determination of the decomposing capability for NH3, CH3SH and CH3CHO. The deodorant activity(D.A.) of these deodorizing fibers was measured by chromogenic gas detector tubes. The deodorizing effect of the prepared fibers were shown to be similar for the three model compounds; 5wt% TiO2 sol solution calcined at 450℃ < 5 wt% TiO2 sol solution calcined at 500℃ < 5 wt% TiO2 sol solution calcined at 750℃.
