Реферат: An antimicrobial nonwoven wet wipe includes i) a fibrous nonwoven substrate bonded with a cross-linkable VAE dispersion stabilized with one or more cationic protective colloids out of the group of cationic vinyl alcohol -N-vinyl amine copolymers, and ii) absorbed in the nonwoven substrate, an aqueous lotion including one or more cationic disinfectants. No anionic surfactants are present in the antimicrobial nonwoven wet wipe. A method of producing the antimicrobial nonwoven wet wipe includes a) applying a first aqueous composition including a cross linkable VAE dispersion stabilized with one or more cationic protective colloids out of the group of cationic vinyl alcohol-N-vinyl amine copolymers to a nonwoven substrate; b) drying the composition; and c) applying a second aqueous composition to the product of step b). At least one of the first and second aqueous compositions includes one or more cationic disinfectants.
