Abstract
There is provided a protective media and a method of manufacturing the same. In one aspect, the protective media includes a porous dielectric carrier, an active agent incorporated in the porous dielectric carrier, and an electrostatic charge across at least a portion of the porous dielectric carrier. This innovative media is capable of eradicating microorganisms and/or toxins more efficiently than prior art solutions and can also self sterilize.

A protective media including:
- a porous dielectric carrier;
- an active agent incorporated in said porous dielectric carrier;
- and
- an electrostatic charge across at least a portion of said porous dielectric carrier.
1 more element
A protective media including:
- a first porous dielectric carrier;
- a first active agent incorporated in said first porous dielectric carrier;
- an electrostatic charge across at least a portion of said first porous dielectric carrier;
- a second porous dielectric carrier;
- a second active agent incorporated in said second porous dielectric carrier;
- and
- an electrostatic charge across at least a portion of said second porous dielectric carrier.
4 more elements
A method of making a non-woven material including:
- providing an extruder having an outlet;
- providing a collecting web below the outlet of said extruder;
- providing a hot melt of extrudable material;
- extruding said extrudable material with said extruder to provide a flow of cooling extruded fibers to fall toward said collecting web;
- and
- providing a cloud of an active agent at a location adjacent said outlet of said extruder so that said cloud envelops the cooling fibers while said fibers are still in a quasi-liquid quasi-solid state so that said active agent settles and collects and is intermeshed or entrapped with said fibers on the collecting web forming a media.

A method of making a non-woven material including;
- providing an extruder having an outlet;
- providing a collecting web below the outlet of said extruder;
- providing a reservoir of extrudable material;
- extruding said extrudable material with said extruder to provide a flow of extruded fibers to fall toward said collecting web;
- and
- providing a cloud of an active agent at a location adjacent said flow of extruded fibers so that said cloud envelops the fibers while said fibers are falling so that said active agent settles and collects and is intermeshed or entrapped with said fibers on the collecting web forming a media.
