Abstract

The invention discloses antibacterial fibers with a copper-based metal organic framework. The antibacterial fibers with the copper-based metal organic framework are prepared from 80-99.9% of polyester, 0.1-20% of a copper-based metal organic framework material and an antibacterial agent, wherein the antibacterial agent is at least one of a quaternary ammonium salt antibacterial agent of vitamin C at the mass percent concentration of 5-20% and a halamine antibacterial agent of vitamin C at the mass percent concentration of 5-20%. A method for preparing the antibacterial fibers comprises the steps that the copper-based metal organic framework material and polyester are subjected to melt spinning with a spinning machine, and copper-based metal organic framework and polyester composite fibers are obtained; the copper-based metal organic framework and polyester composite fibers are steeped into the antibacterial agent, then rinsing and drying are carried out, and the antibacterial fibers with the copper-based metal organic framework are obtained. The obtained antibacterial fibers with the copper-based metal organic framework have good antibacterial performance and are simple in preparing method.
