PURPOSE: To provide an antiseptic material which is quite stable in wide pH ranges wherein the material comprises a graft polymer capable to form a complex with metal ion having an antiseptic action.
CONSTITUTION: A fiber material to be grafted, for example in the case of hydrophobic synthetic fibers, is at first activated by electronic irradiation, and thereafter impregnated into a monomer soln. of glycolic ester such as phosphate of ethylene glycol methacrylate or 8-hydroxyquinoline acrylate, heated, graft polymerized, and then passed continuously through several solutions of metal ions having an antiseptic action such as ionic solutions of copper, zinc, tin and mercury, and complexed, to obtain an antiseptic material which is stable in wide pH ranges. For the cases of hydrophilic fibers, the fibers are impregnated into the monomer soln. at first and thereafter grafted by the electronic irradiation.
