A molded antimicrobial article comprises an infiltrated antimicrobial agent which forms independent phases of 0.01 µm or more in shorter diameter in the molded article. It is preferable that 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 that 50% or more of the antimicrobial agent is infiltrated in a depth range of 0.5, preferably, 1 µm 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 µm or more from the surface of the molded article. It is also preferable that the molded article is fibers, that the surface area used per 1 g of fibers is 0.1 m2 or more, and that the synthetic fibers are a colored antimicrobial fibrous product.
The molded antimicrobial article of the present invention can be obtained, for example, by immersing a fibrous product in a dyeing liquid containing a pyridine based antimicrobial agent with a molecular weight of 200 to 700, an inorganic property/organic property value of 0.3 to 1.4 and an average particle size of 2 µm or less, and treating simultaneously with dyeing under pressurization, or by applying a liquid containing a pyridine based antimicrobial agent with a molecular weight of 200 to 700, an inorganic property/organic property value of 0.3 to 1.4 and an average particle size of 2 µm or less to a fibrous product by padding or spraying, and heat-treating it at 160 to 200°C in dry or wet state.
一种模塑抗菌制品包括一种浸润抗菌剂,该抗菌剂在模塑制品中形成短直径为 0.01 微米或以上的独立相。抗菌剂最好是基于吡啶的抗菌剂,分子量在 200 到 700 之间,无机性质/有机性质值在 0.3 到 1 之间,50%或更多的抗菌剂浸润在距离模塑制品表面 0.5 微米(最好是 1 微米)或更大的深度范围内,或者 30%或更多的抗菌剂浸润在距离模塑制品表面 2 微米或更大的深度范围内。此外,成型品最好是纤维,每 1 克纤维使用的表面积为 0.1 平方米或以上,合成纤维最好是有色抗菌纤维制品。
本发明的模塑抗菌制品可通过将纤维制品浸入含有吡啶类抗菌剂的染色液中获得,吡啶类抗菌剂的分子量为 200 至 700,无机性质/有机性质值为 0.3 至 1.4 和平均粒径为 2 微米或更小的吡啶基抗菌剂的染色液中,并在加压下与染色同时进行处理,或通过轧制或喷涂将含有分子量为 200 至 700、无机物特性/有机物特性值为 0.3 至 1.4 和平均粒径为 2 微米或更小的吡啶基抗菌剂的液体涂抹到纤维制品上,并在 160 至 200°C 的干燥或湿润状态下进行热处理。
