The present invention provides a method for preparing an antimicrobial treatment agent for textiles, including steps of: (S1) providing substances of: (a) divalent copper ion salt; (b) ammonia water or ammonium salt; (c) an inorganic alkaline aqueous solution; (d) an organic substance of alcohols or carbohydrates containing only carbon, hydrogen and oxygen elements; (e) water; and (S2) mixing and ageing above solutions using alcohols or carbohydrates as a catalyst to form a compound of a copper ammonium complex. In the method for preparing an antimicrobial treatment agent for textiles of the present invention, the treatment agent does not contain a heavy metal or an organic element that may have toxicity, for example, nitrogen, phosphorus or sulfur, an alkaline material used for treating the textile does not contain a non-volatile or an organic amine compound, an organic substance such as alcohols or carbohydrates is skillfully used as a catalyst, and copper ions form a complex for transition, so that natural textile fibers are grafted to copper ions more tightly and have advantages of safety, environmental friendliness, scrub resistance, a high antibacterial effect and long life of service.
