1. An antimicrobial detergent composition, comprising the following components by mass percent:
a compound formed by 0.1-10% of a polyester-polyether polymer and 0.01-2% of an antimicrobial agent with a halogenated phenol structure;
10-50% of a surfactant; and
a solvent,
wherein a 1% deionized water solution of the antimicrobial detergent composition has a pH value of 7.0-9.0,
wherein the compound is formed by pre-mixing the polyester-polyether polymer and the antimicrobial agent with the halogenated phenol structure in the following steps:
a) dissolving the antimicrobial agent with the halogenated phenol structure into the solvent to prepare a solution A with a concentration of 20-40 wt %;
b) dissolving the polyester-polyether polymer into the solvent to prepare a solution B with a concentration of 40-70 wt %;
c) conducting stirring mixing on the solution A and the solution B to obtain a uniform solution; and
d) slowly adding water into the uniform solution obtained in step c) for stirring to obtain a uniform compound solution,
wherein in step a) and step b), the solvent is one or more selected from the group consisting of isopropanol, 1,2-propanediol, dipropylene glycol, diethylene glycol butyl ether and ethylene glycol;
wherein the polyester-polyether polymer comprises a fabric-friendly segment formed by a condensation reaction of a terephthalate and a diol, and a hydrophilic segment comprising a segment consisting of ethylene oxide repeating units;
wherein the antimicrobial agent is one or more selected from the group consisting of 5-chloro-2-(2,4-dichlorophenoxy) phenol, chlorodimethylphenol and 5-chloro-2-(4-chlorophenoxy) phenol.
