Abstract

Provided are an antimicrobial fiber that exhibits predetermined antimicrobial properties even after being washed 50 times or more and a method of manufacturing the antimicrobial fiber. This antimicrobial fiber comprising a thermoplastic resin and antimicrobial glass particles and a method of manufacturing the same are characterized in that the surface of the antimicrobial fiber has cracks along the longitudinal direction of the antimicrobial fiber and each crack holds at least one of the antimicrobial glass particles therein.

Description

technical field [0001] The present invention relates to an antibacterial fiber and a method for producing the antibacterial fiber. In particular, it relates to an antibacterial fiber and a method for producing the antibacterial fiber that exhibit predetermined antibacterial properties even after repeated washing dozens of times. Background technique [0002] Conventionally, in order to impart an antibacterial effect to fiber products, antibacterial fibers containing antibacterial particles in the fibers have been used. [0003] As a method of producing such antibacterial fibers, there are a method of attaching antibacterial particles to fibers after spinning, and a method of mixing antibacterial particles into a resin material before spinning. [0004] As antibacterial fibers obtained by attaching antibacterial particles to fibers after spinning, a method obtained by immersing cotton cloth in a dispersion of silver-containing zeolite particles and polyether resin and then d...
