Process for preparing Antimicrobial Elastic fiber

摘要

Disclosed herein is a process for preparing an antimicrobial elastic fiber. The process comprises: mixing a glass compound, as an antimicrobial agent, containing ZnO, SiO₂, and an alkali metal oxide, and having an average particle size of 0.1 mum to 5 mum, with a dispersant; sand grinding or milling the mixture; and adding the ground or milled mixture to a solution of a segmented polyurethane polymer to prepare an elastic yarn. The process can provide advantageous effects that spinnability is improved and the color of yarn remains unchanged.
