Document Type and Number:
WIPO Patent Application WO2005035866
Kind Code:
A3
Abstract:
Disclosed is an integrated paper wherein the paper has capabilities and functionalities provided by both the fiber and the active agent ingredients, and a method of immobilizing the active agents within the integrated paper. The tight pore structure of the integrated paper of the present invention, a mean pore diameter of less than about 2 microns, provides short diffusion distances from a fluid to the surface of the paper ingredients by adsorption or diffusive interception making it an excellent medium for fluid filtration. The integrated paper of the present.. invention can further -include a microbiological interception enhancing agent. The integrated paper can be formed using, preferably, wet laid paper-making processes for speed and efficiency. Also disclosed are devices utilizingthe integrated paper usëful in fluid filtration.
