Abstract
The present disclosure provides fibrous composition comprising a soluble or a dispersible N-halamine, for example 1-chloro-2,2,5,5-tetramethyl-4-imidazolidinone (i.e., compound I). Additionally, the disclosure provides methods for producing the fibrous compositions comprising a soluble or a dispersible N-halamine as well as methods for protecting a person from an infection using the fibrous compositions comprising a soluble or a dispersible N-halamine. The compositions and methods according to the present disclosure provide several advantages, such as stability, less time to provide sufficient antimicrobial inactivation, and are inexpensive and require lower amount of active concentrations to be effective.
