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.
本发明涉及一种模塑抗菌制品,包括一种渗入的抗菌剂,该抗菌剂在模塑制品中形成短直径为 0.01 &mgr;m 或更大的独立相。抗菌剂是一种吡啶类抗菌剂,其分子量为 200 至 700,无机性质/有机性质值为 0.3 至 1,50% 或更多的抗菌剂在距离模塑制品表面 0.5 &mgr;m 或更大的深度范围内浸润,或 30% 或更多的抗菌剂在距离模塑制品表面 2 &mgr;m 或更大的深度范围内浸润。将纤维制品浸入含有吡啶类抗菌剂的染色液中,同时在加压条件下进行染色处理,或将含有吡啶类抗菌剂的液体以轧制或喷涂的方式涂抹到纤维制品上,然后在 160 至 200 摄氏度的干燥或潮湿状态下进行热处理,即可获得本发明的模塑抗菌制品。
