PURPOSE:To obtain the title anti-fungus agent with high washing fastness by making metallic ions having anti-fungal effect adsorb to a phenolic chelate resin. CONSTITUTION:Firstly, phenolic chelate resin powder is prepared by polycondensation between a phenol, aldehyde and chelating agent (e.g. diethylenetriamine, iminodiacetic acid) at the molar ratio: chelating agent/phenol = 0.1-1.0 (pref. 0.2-0.5). The present powder is then mixed with an aqueous solution containing an anti-fungal metal (pref. silver, copper or zinc) salt, thus obtaining the objective anti-fungus agent. A textile is coated with this anti- fungus agent together with a resinous binder to obtain a cloth having anti-fungal effect with both high washing fastness and persistence. |
