Manufacturing Method of Antimicrobial Fiber Using Nano Silver Powder

Abstract

Disclosed is a method for manufacturing a method for manufacturing antimicrobial fiber using nano silver powder, which can greatly increase the antimicrobial and bactericidal activities of fiber by preparing nano silver particles with high dispersibility and high purity in a continuous and easy manner and allowing fiber yarn to contain the prepared nano silver particles in an optimal manner. The method the steps of: dissolving a silver precursor in solvent; spraying the precursor solution in the form of fine droplets by any one technique selected from ultrasonic spraying, air-assist spray nozzle spraying and pressure nozzle spraying; transferring the sprayed droplet precursor into a thermal reactor or a flame reactor by carrier gas; decomposing the transferred precursor by heating at a temperature of 400-2,000° C. to prepare nano silver particles; collecting the prepared nano silver particles in a collector while cooling with cooling fluid of less than 200° C.; preparing master batch chips using the prepared nano silver particles; and mixing yarn raw material with the master batch chips to manufacture fiber yarn.
