Summary:A fibrous web that includes a cationic polymer that contains a cationic monomer comprising a cationic functional group having an affinity for the negatively charged cell walls of bacteria and a hydrophobic monomer comprising a hydrophobic functional group is provided. The molar ratio of the cationic monomer to the hydrophobic monomer is greater than about 1:1. The affinity of the cationic polymer for the bacteria allows the web to capture bacteria, thereby removing them from a surface or liquid, without the use of harsh chemicals, and also inhibiting their spread to other surfaces and liquids that may contact the web. Se proporciona una trama fibrosa que incluye un polímero catiónico que contiene un monómero catiónico que comprende un grupo funcional catiónico que tiene una afinidad por las paredes celulares cargadas negativamente de las bacterias y un monómero hidrófobo que comprende un grupo funcional hidrófobo. La relación molar del monómero catiónico al monómero hidrófobo es mayor que aproximadamente 1:1. La afinidad del polímero catiónico por las bacterias permite que la trama capture las bacterias, eliminándolas de este modo de una superficie o líquido, sin el uso de químicos fuertes, e inhibiendo además su propagación hacia otras superficies y líquidos que puedan ponerse en contacto con la trama.
