Abstract: 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.

Abstract: An antimicrobial composition of coniferous resin acids and solvent, such as alcohol, water, and an auxiliary solvent selected from E and P series glycol ethers is disclosed. The method for manufacturing of the antimicrobial composition is also disclosed, where in the first step coniferous resin acids, alcohol, auxiliary solvent and water are provided; in the second step alcohol is mixed with water; in the third step coniferous resin acids, auxiliary solvent, as well as optionally a wetting agent, water and/or a pH regulator are added into the alcohol-water solution from second step, and mixed until clear; in the fourth step the antimicrobial composition is optionally packaged and/or diluted to obtain an alcoholic antimicrobial composition with coniferous resin acid concentrations more than 0.01 weight-%. The disclosure relates further to the use of the antimicrobial composition as disinfectant for inanimate and/or living surfaces.
