In order to address the sustainability and environmental issues associated with conventional HVAC filters, inventive HVAC filters have been developed that are completely biodegradable and compostable and exhibit Minimum Efficiency Reporting Value (MERV) ratings that are superior to conventional HVAC filters. More particularly, it has been discovered that biodegradable electrospun nanofibers can be used to produce biodegradable HVAC filters that exhibit superior filtration performance relative to conventional HVAC filters produced from polypropylene electrostatic media or triboelectric nonwoven media.

A long-life in filters is required as filter members for slurry liquid having high-viscosity and high-solid-content ratio. It is provided to solve the problem, the filter element for filtering slurry liquid, wherein nets and non-woven fabrics are alternately layered, wherein each of the nets has first fibers parallelly extending in one direction and second fibers parallelly extending in a direction angled to the one direction and contacting sides of the first fibers, wherein the first and second fibers forms mesh-pores at portions surrounded by the first and second fibers, wherein each of the non-woven fabrics has protrusions on surfaces of the each of the non-woven fabrics in a thickness-direction, the protrusions formed to repeatedly come out on the surfaces of the each of the non-woven fabrics in a surface-direction of the each of the non-woven fabrics.

The present invention aims to provide a nanomesh laminate with which a conductive nanomesh material can be easily placed on a desired site and which is less likely to undergo distortion upon attachment. The object is achieved with a nanomesh laminate including: a mesh-shaped base material (A); and a nanomesh layer (B) containing a polyvinyl alcohol resin as a main component; the mesh-shaped base material (A) and the nanomesh layer (B) being layered next to each other, preferably achieved with a nanomesh laminate including: a nanomesh layer (B) containing polyvinyl alcohol as a main component; and a conductive substance layer (C); on a mesh-shaped base material (A).

A self-adhering drainage-promoting wrap for a building structure includes an elongate, flexible strip of weather-resistive membrane having front and rear faces, a series of separate, spaced-apart, spacer elements bonded to the front face of the membrane and projecting therefrom to a predetermined height, and a layer of adhesive on the rear face of the membrane. Wall and roof assemblies including the self-adhering drainage-promoting wrap are also provided.

An elastic body for holding a cosmetic, which can suppress that the cosmetic included in the elastic body for holding a cosmetic is taken out from the elastic body in a large amount at a time at the initial stage of use, wherein the elastic body for holding a cosmetic has a three-dimensional structure, and at least a dense fibrous surface layer and a sparse fibrous substrate; a cosmetic-containing elastic body in which a cosmetic is included in the elastic body for holding cosmetic; and a cosmetic article having the cosmetic-containing elastic body.

A drainage/ventilation product is placed in a budding structure. The product includes: a weather barrier membrane faces away from the building structure; a drainage structure affixed to and co-extensive with the weather barrier membrane; a moisture resistant layer affixed to and co-extensive with the drainage structure; an adhesive layer, the adhesive layer is a plurality of adhesive strips and/or scatter coated over and co-extensive with the moisture resistant layer, the adhesive is a pressure sensitive adhesive (PSA) and has a pull adhesion in a range of about 10-21 psi, and covers about 40-95% of a surface of the moisture resistant layer; and a release layer releasably covers and is co-extensive with the adhesive layer. Whereby the moisture/ventilation product is placed on the building structure without mechanical fasteners. A method is also disclosed.
