The invention relates to a textile sheetlike material impregnated with an antimicrobial active ingredient preparation. The active ingredient preparation comprises bispyridiniumalkane, in particular octenidine dihydrochloride. The support material is a polyolefin, in particular polypropylene, which prevents the adsorption of the bispyridiniumalkane on the support material of the sheetlike structure. Moreover, the invention relates to a kit of support material and active ingredient preparation for producing such sheetlike structures.
