Abstract: Geotextile composite configured to filter liquids and related methods are provided. The geotextile composites include a pre-filter layer, a post-filter layer and at least two intermediate filter layers disposed between the pre-filter layer and the post-filter layer. At least one fibrous web that includes composite fibers and adsorptive particulates is disposed between the at least two intermediate filters. The fibrous web has a structural component, and a thermally-bondable, polymeric component. The geotextile can be placed in a location where a liquid that contains contaminants therein resides. The liquids can pass through the geotextile such that the liquid contacts the adsorptive particulate. The contaminants are then filtered from the liquid through contact of the contaminants with the adsorptive particulate.

Abstract: A deodorizing air filter media which is composed of a web of non-woven fibers having myriad discrete particles of a deodorizing component, such as sodium bicarbonate, uniformly dispersed throughout the thickness of the web. The media is fabricated by a two step process, wherein a non-woven web is passed through a first aqueous solution including a binder, and then dried to cured the binder and anchor the crossing points of the fibers in the web. Next, the dried web is passed through a second aqueous solution having a binder in a reduced concentration, together with a particulate deodorizing component suspended therein. The web is then again dried to cure the newly added binder and anchor the particulate deodorizing component to the fibers.
