Abstract: The invention is directed to a microbiological interception enhanced filter medium, preferably having an adsorbent prefilter located upstream from the filter medium. Preferably, the prefilter is adapted to remove natural organic matter in an influent prior to the influent contacting the microbiological interception enhanced filter medium, thereby preventing loss of charge on the filter medium. The microbiological interception enhanced filter medium is most preferably comprised of fibrillated cellulose fibers, in particular, lyocell fibers. At least a portion of the surface of the at least some of the fibers have formed thereon a microbiological interception enhancing agent comprising a cationic metal complex. A filter medium of the present invention provides greater than about 4 log viral interception, and greater than about 6 log bacterial interception.

Abstract: Carbon or activated carbon nanofibers are made from fibrillated nanofibers having a Canadian Standard Freeness of less than about 100, and/or a fiber diameter of less than or equal to about 400 nm. BET surface areas are greater than about 800 M2/g. The fibrillated nanofibers can be made into a precursor paper and subjected to heat treatment to form carbon or activated carbon nanofiber sheets. A method of making is disclosed wherein carbonization occurs at a temperature of less than about 600 °C. Activation occurs at temperatures greater than about 875 °C in less than or equal to about 30 minutes in an oxidizing atmosphere. Single step carbonization and activation in an oxidizing atmosphere is also disclosed. The carbon nanofibers or structures made therefrom are useful as filter media providing efficient adsorption and interception of microbiological contaminants due to the microporous carbon nanofiber structure.

Abstract: One or more particulate active agents are fused to the surface of a substrate web by mixing the particulate agents with a particulate binder having a particle size not exceeding an average diameter of approximately 40 microns and coating the composite mixture onto the surface of the substrate. Thereafter; the coated substrate is heated to a temperature equal to or greater than the Vicat softening temperature of the binder and compressed within the nip of a pair of pressure rolls to achieve fusion. If desired, a top layer may be placed upon the coated composite prior to the compression step. Also disclosed are various products manufactured by the process.

Abstract: A process for making fibrillated fibers includes preparing a fluid suspension of fibers, low shear refining the fibers at a first shear rate to create fibrillated fibers having a reduced CSF, and subsequently higher shear refining the fibers at a second shear rate, higher than the first shear rate, to increase the degree of fibrillation of the fibers. The refining at the first shear rate may be with a rotor at a first maximum shear rate and the refining at the second shear rate may be with a rotor at a second maximum shear rate, higher than the first maximum shear rate. The process may further include pre-treating the fibers by high shear refining with impact to stress the fibers prior to low shear refining.
