Abstract
An antibacterial property imparting glass composition is provided, which may be fixed in a form of, for example, a particle on the surface of a fiber substrate and/or dispersed and complexed in the fiber substrate. Such an antibacterial property imparting glass composition comprises 0.1 to 5.0% by weight of Ag2O in a composition containing 45-67 mol % of P2O5, 5 to 20 mol % of Al2O3, 1 to 40 mol % of 1 or 2 or more selected from MgO, CaO and ZnO, and 20 mol % or less of B2O3. An antibacterial fiber containing such an antibacterial property imparting glass composition at a ratio of, for example, 0.1 to 5.0% by weight shows high water resistance, acid resistance, alkali resistance and detergent resistance in antibacterial property.
