Abstract
The invention relates to a molded antimicrobial article including an infiltrated antimicrobial agent which forms independent phases of 0.01 &mgr;m or more in short diameter in the molded article. The antimicrobial agent is a pyridine based antimicrobial agent with a molecular weight of 200 to 700 and an inorganic property/organic property value of 0.3 to 1, and 50% or more of the antimicrobial agent is infiltrated in a depth range of 0.5 &mgr;m or more from the surface of the molded article, or that 30% or more of the antimicrobial agent is infiltrated in a depth range of 2 &mgr;m or more from the surface of the molded article. The molded antimicrobial article of the invention can be obtained by immersing a fibrous product in a dyeing liquid containing the pyridine based antimicrobial agent, and treating simultaneously with dye under pressurization, or by applying a liquid containing a pyridine based antimicrobial agent to a fibrous product by padding or spraying, and heat-treating it at 160 to 200° C. in a dry or wet state.
