PROBLEM TO BE SOLVED: To obtain the subject polymer raw material exhibiting a wide antibacterial spectrum against a pathogenic bacterium and capable of exhibiting excellent durability by previously introducing a compound having a ligand capable of coordinating to a metal ion and dipping into an aqueous solution of an antibacterial metallic salt. SOLUTION: This antibacterial polymer raw material is obtained by introducing a polyphenol (preferably tannic acid, catechin and flavonoid) as a spacer having an action bondable with a polymer raw material (preferably silk protein, wool, collagen, a cotton fiber, a diacetate fiber or the like) by treating in an acidic aqueous solution of the polyphenol at pH 1-3 and coordinating an antibacterial metallic ion (preferably a silver ion, a copper ion or the like) to the polymer raw material through the spacer. The polymer raw material is obtained by introducing the polyphenol into a polymer raw material and coordinating a metallic ion by dipping into an aqueous solution containing an antibacterial metal. |
