Antibacterial properties imparting glass composition, antibacterial fiber, antibacterial twist and antibacterial fabric

摘要

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 fiber200, an antibacterial property imparting glass composition10 is fixed in a form of, for example, a particle on the surface of a fiber substratel6 and/or dispersed and complexed in the fiber substratel6. An antibacterial property imparting glass composition10 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 fiber200 containing such the antibacterial property imparting glass composition10 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.
