GLASS COMPOSITION FOR IMPARTING ANTIBACTERIAL PROPERTY, ANTIBACTERIAL COMPOSITE MATERIAL, AND ANTIBACTERIAL FIBER

摘要

PROBLEM TO BE SOLVED: To provide a glass composition for imparting antibacterial properties in which problems such as discoloration and dissolution are hard to occur in the production and working processes of fiber, and having high durability, to provide an antibacterial composite material obtained by compounding the same into a chemical fiber, and to provide an antibacterial fiber obtained by spinning the antibacterial composite material and having high fiber strength and antibacterial properties.;SOLUTION: The glass composition for imparting antibacterial properties is composed by adding 0.1-5.0 wt.% Ag₂O to a glass composition consisting of, by mol, 30 to 60% P₂O₅, 5 to 35% of one or more kinds selected from K₂O, Na₂O and Li₂O, 5 to 35% of one or more kinds selected from MgO, CaO and ZnO, 4 to 20% Al₂O₃, 0.01 to 5% of one or two kinds selected from La₂O₃ and Y₂O₃. The antibacterial composite material is composed by adding the glass composition to a chemical fiber.;COPYRIGHT: (C)2005,JPO&NCIPI
