A non-woven electret fibrous web for electrostatic adsorption and odor elimination and the preparation process thereof. In certain exemplary embodiments, the non-woven electret fibrous web includes a multiplicity of electret fibers, at least one of a plurality of photo-catalytic fibers or a plurality of multi-component fibers; and optionally, at least one of a plurality of chemically-active particulates, a plurality of carbon-based fibers, or a plurality of mono-component thermoplastic fibers. In other exemplary embodiments, carding and cross-lapping or air-laying processes are disclosed for making nonwoven fibrous webs including electret fibers and one or more of photocatalytic fibers, chemically-active particulates, multi-component fibers, mono-component thermoplastic fibers, or carbon-based fibers. In some exemplary embodiments, exemplary non-woven electret fibrous webs of the disclosure exhibit superior gas permeation characteristics, high adsorption characteristics for airborne contaminants, as well as an odor elimination function.

Provided is an injection molded panel having a top side and a bottom side. The panel is configured with at least an elastic portion, the elastic portion including a plurality of undulating deformable strands intersecting with one another at rigid connecting locations, the rigid connecting locations alternatingly extending at opposite sides of the panel at alternating top peaks and bottom peaks, the peaks defining together the respective top side and the bottom side.
