METHOD FOR PREPARING SILVER NANOCOATED ANTIBACTERIAL FABRIC

摘要

A manufacturing method of antibacterial fiber in which nanosilver particle is coated is provided to control arbitrarily a size and a thickness of nanosilver particle coated on the fiber by controlling a relative concentration of a reactant. A manufacturing method of antibacterial fiber in which nanosilver particle is coated comprises a step of coating the nanosilver particle on fiber containing an alcohol functional group using a mixture including silver ion and aliphatic group or an aromatic amine compound. A pKa of the aliphatic group or the aromatic amine compound is 5 or greater. A relative concentration of the aliphatic amine compound and the silver ion is 1:0.1 or 1:5. A total concentration of the aliphatic amine compound and the silver ion is 10^-6 - 1 mol/liter.
