Abstract: An antimicrobial detergent composition includes the following components by mass percent: 0.1-10% of a polyester-polyether polymer, 0.01-2% of an antimicrobial agent with a halogenated phenol structure, 10-50% of a surfactant and a solvent. A 1% deionized water solution of the detergent composition has a pH value of 7.0-9.0. In the present invention, by introducing the polyester-polyether polymer into the composition, the deposition efficiency of the antimicrobial agent with the halogenated phenol structure on a fabric can be improved, a solubilization effect of the surfactant in a detergent can be reduced, and therefore, a antimicrobial effect is achieved.
