The application relates to a process for producing fibrous material with antimicrobial properties, wherein in the first step coniferous resin acid composition is emulsified into aqueous solution with emulsifier and wetting agent, and in the second step thus formed emulsion is transferred into fibrous material by impregnation. Further, the application relates to an aqueous antimicrobial composition for use as a water-soluble concentrate in the treatment of fibrous materials, and to a fibrous material with antimicrobial properties, and to its use in e.g. fabrics, fur, leather, clothes, canvas, tissues, plastics, webs, accessories, packaging materials, wallpapers, food-related products, household products, footwear, construction materials, insulating materials and medical products.

A coating film has a surfactant having a hydrophobic group or a lipophilic group and a hydrophilic group, and a film having holes on a surface thereof capable of carrying the surfactant. The surfactant has the lipophilic group of 5 or more carbon atoms and does not evaporate at room temperature. The film is a porous film. A porosity of the porous film is 5% or more and 60% or less. The surfactant is an abietic acid-based compound. Alternatively, the surfactant is chlorhexidine. A hole diameter of the holes is greater than 10 times as large as a size of a virus.
