Antibacterial property imparting glass composition, antibacterial fiber, antibacterial twisted yarn and antibacterial cloth

Abstract

There is provided an antibacterial fiber, an antibacterial twisted yarn and an antibacterial cloth which exhibits high durability to post-processing with water, detergent, staining or the like at a small added amount. In an antibacterial fiber 200, an antibacterial property imparting glass composition 10 is fixed in a form of, for example, a particle on the surface of a fiber substrate 16 and/or dispersed and complexed in the fiber substrate 16. An antibacterial property imparting glass composition 10 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 200 containing such the antibacterial property imparting glass composition 10 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.
