Beschreibung
Zusammenfassung: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.
